Dear Heritage Foods USA Supporter,
Thank you for all your positive feedback on our most recent press release. In fact last week's email was so well received, we have included it again below for those who might have missed it!
We also wanted to bring attention to three recently published books that prominently feature Heritage Foods USA and its network! We hope you go out and buy these books! We are happy to see so many books come out about the new revolution in sustainable meats!
Thank you for your support. We look forward to an exciting New Year filled with exciting projects that help producers raising food the right way!
"Deborah Krasner is part of a revolution in food, in agriculture, in nutrition, that is taking place in our nation."
̶ Vermont Senator Bernie Sanders
"Good Meat is a template for all future cookbooks: one that educates on the culinary differences between factory-farmed meats and animals raised on family farms, and the utilization of the entire animal in a sustainable manner."
- Patrick Martins
Both a cookbook and a guide, Deborah Krasner's GOOD MEAT offers a complete look at sourcing, preparing, and cooking sustainably raised meat. Krasner demystifies terms such as grass fed and locavore while demonstrating the connection between responsible agriculture and delicious food.
With more than 200 recipes for pork, beef, lamb, poultry, and game; stunning photos; and easy-to-follow directions for ordering directly from the farm, this groundbreaking book is a must-have for the modern American kitchen. As U.S. Senator Bernie Sanders writes in the foreword, "GOOD MEAT…shows us how, as we eat more healthily and sustainably, we can also cook, and eat, with great delight."
Primal Cuts is written by Marissa Guggiana. Food activist, writer, and fourth generation meat purveyor, Marissa traveled the country to discover fifty of our most gifted butchers and share their favorite dishes, personal stories, and cooking techniques. One of those butchers was our very own: Nick Fantasma, plant manager of Paradise Locker Meats! CONGRATULATIONS NICK!
Butchery was nearly a dead art, until a recent renaissance turned progressive meat cutters into culinary cult idols. Inspired by a nose-to-tail approach to butchery, this new wave of meat mavens is redefining the way we buy and cook our beef, pork, fowl, and game. The momentum of this revived butcher-love has created a carnivorous frenzy, pulling a new generation of home cooks straight into the kitchen—Primal Cuts: Cooking with America's Best Butchers is their modern meat bible.
Laura C Martin's GREEN MARKET BAKING BOOK offers a unique collection of 100 mouthwatering sweet and savory baked treats chosen from the best chefs and bakers from across America. From cookies and cakes to pies and pastries, these delightful goodies are all created from locally produced sustainable whole foods, natural sweeteners, dairy- and gluten-free treats, along with vegan and low-fat variations.
Some of the seasonal recipes included in the book are:
Foreword by Patrick Martins
Ever since the eighteenth century, to be slow was to obstruct progress, civilization. Nature's secrets were unlocked and we discovered her quicksilver side: electricity, the speed of light, the incomprehensible whirl of subatomic particles. We built our civilization upon the assumption that speed is equivalent to efficiency and that efficiency is equivalent to "saving" time, as if seconds can be hoarded and spent later. Progress was good. Faster was better.
Thanks in part to the Slow Food movement, our culture has reevaluated "slow." Now, "taking" time can be as worthwhile as "saving" it, whether seeking out a small business that specializes in a craft or baking a pie with family and friends using fruits from the local farmers' market. Without challenging its value, we now recognize a more sophisticated understanding of efficiency. It is an understanding that, perhaps unsurprisingly, returns our respect for natural rhythms.
The fast-faster-fastest emphasis of commodity culture, coupled with the relentlessness of globalization, fills our world with both frenzy and glut. Many companies have moved faster than their ability to produce decent products. Witness 2007: the "Year of the Recall." Factory farming, mad cow disease, and E. coli spread when reckless speed and profit seeking trumped sounder, but slower, values. When consumers are dying and the environment is being ravished, when workers' rights are compromised and community bonds are dissolving—all as a consequence of our fast-faster-fastest method of doing business—the results can hardly be construed as efficient.
The traditions and simplicity of growing and eating food in time-tested ways have become a mere memory. The fast-faster-fastest mentality is marked by ignoring the qualities people cherish most in order to promote those aspects of a commodity that make it more valuable to store, ship, and sell. Simply proposing an alternative to the global economy will not work—"global alternatives" are abstract figments. The only true alternatives are those that exist within the domain of personal choice. Business practice conforms to the international economy that has emerged like a constellation from the accumulation of millions of personal choices made across the planet every day. The only way we can create change is to work within that economy, and the only way we will succeed in influencing personal choices is by influencing the value system people draw upon when making those choices.
Laura Martin's book describes in great and delicious detail a choice that is very different than those proposed by the world's richest food companies. The proliferation of artificial sweeteners, processed chemicals, and high levels of refined sugars in store-bought food is a tragic circumstance sanctioned by those in power, one that has turned this generation into the first ever to not live longer than the one that preceded it. The answer to satisfying your sweet tooth without poisoning your body is to use local and seasonal fruits, vegetables, and herbs, along with whole grains and natural sweeteners. By eating like this, your destiny is in your hands, and the result is a healthier body, a healthier environment, and healthier local food communities.
Sweets are the very definition of pleasure, and taking the time to bake with family and friends is a way of prolonging that pleasure. I assure you that you will love reading and making the recipes in this book, from chef Linton Hopkins's honey whole wheat or rosemary olive breads, to Alice Waters's famous whole-wheat waffles.
The fast-faster-fastest business of commodities makes similar, but lesser, versions of products and charges little for them, burying the true cross of their charade in a tab that they expect society—and the environment—to pay. By reading this book you will support a virtuous production system, include a little sweetness in your life, and find great recipes that you won't have to pay for later.

Heritage Foods USA was founded ten years ago as a response to dwindling options in the marketplace for high-quality, humanely raised meat products grown by small and medium sized independent farmers. This segment of the agricultural population is being squeezed out of business by a government in harness with trade organizations that support high volume production at grotesquely low prices. As a result of US farm policies, thousands of family farms have gone under, and the loss of cultivated land has put our future domestic food supply at risk. Thanks to the support of our partners, Heritage Foods USA has managed to pump $20 million into small agriculture-related business, slowly but surely helping to reverse this trend.
We now enter 2011 with a new Heritage Foods USA Manifesto! We will continue to build on our milestone triumphs in reviving heritage breeds, increasing awareness of the food supply in the consumer mainstream, and offering farmers a chance to work their farms in a way that best serves the land, the animals, the consumer, and themselves. In addition, we are adding some radical new projects that will continue to change our food landscape for the better:
A SOCIAL BUY of seafood from various regions including the South, where the fishing industry is staggering from natural and unnatural disasters. With the commitment of over 250 restaurant chefs and 30,000 mail order customers, we will organize a Fresh Catch Social Buy, offering a significant influx of cash to seafaring populations. Spearheaded by our Director of Special Projects, Dan Honig, major shipment days will take place on docks across America in the revolutionary sprit of the Slow Food Presidium. The most important aspect to remember here is that the more people that buy, the cheaper each individual order becomes.
NO GOAT LEFT BEHIND: In dairies across America, most male goats are slaughtered and sold for next to nothing while only a few are kept on as breeders. As a result, male goats end up being a burden on dairy farms despite the fact that they descend from some of the best genetics in the world. Led by Communications Director Katy Keiffer, No Goat Left Behind is a project designed to sell every male dairy goat destined for meat use into the mainstream food chain in the New England and Atlantic State region to augment the revenue of dairy farms. No more low commodity pricing!
A CREAMERY in NEW YORK STATE: In New York State over the past two years, thousands of dairy cows have been slaughtered for meat, and dozens of farms shuttered because commodity milk prices are so low farmers cannot afford their cows. Working with Saxelby Cheesemongers, local politicians, and non-profit foundations, we will produce and sell an affordable cheese intended for sandwiches and everyday use, while paying farmers significantly more than commodity pricing for their milk. The goal of this project is that no dairy farmer living close to New York will ever be paid an unfair price for milk.
THE FOOD MUSEUM: Dave Arnold, Director of Culinary Technology at the French Culinary Institute and weekly host of Cooking Issues on Heritage Radio Network, has already launched the concept for a major Food Museum. The project sprang from discussions with the late and much lamented Michael Batterberry of Food Arts Magazine who saw this museum as a critical way to educate and entertain the public about their food supply. Permanent and traveling exhibitions will be modest at first but the eventual goal is that the Food Museum will one day rival the Museum of Natural History as a social force. Stay tuned for information regarding the first fundraising event in spring of 2011.
MAPLE SYRUP: In March, the Heritage team, led by the Director of Mail Order Operations, Andrea Trabucco- Campos, will head to Vermont to work with the Cantor family of Deep Mountain Maple Syrup during the frenetic three-week season when sap runs. The Heritage team will bring needed hands to the harvest, produce informational videos on the true and time-tested art of producing maple syrup, and of course organize a sales campaign to restaurants, home chefs, cure masters, and everyone who just loves maple syrup.
The mission at Heritage Foods USA will always be to support "good, clean, and fair" foods and pricing, as articulated by Carlo Petrini, founder of Slow Food International. As we approach our tenth anniversary and review the success of our mission, we remain steadfast in this commitment.
Heritage Foods USA has been the engine that has helped to revive endangered breeds of poultry and enabled farmers such as Frank Reese to build major new infrastructure and grow his company to include other farmers as passionate as he is about heritage livestock. Many breeds have been upgraded to more stable status on conservation lists. In 2010 we introduced a kosher line of Heritage Turkeys raised on Leaping Waters Farm in Virginia.
We have mobilized farming groups for Berkshire, Red Wattle, Tamworth, and Duroc breeds. We are proud to announce monthly Large Black and Gloucestershire Old Spot supplies starting in Spring 2011. Heritage Foods USA works to make small farms bigger and big farms better. For example Lazy Farm has recently doubled its size to include hundreds of Animal Welfare Approved Six-Spotted Berkshires. Meanwhile Holthaus Farm applied for and received Certified Humane status for its Berkshire supply to comply with our standards. And the Norton family in Missouri has strengthened the Berkshire line on its farm in an effort to achieve 100% Berkshire genetics.
Our wholesale business has given Paradise Locker Meats the opportunity to expand tenfold over the last five years, offering better processing facilities to their region in Missouri as well as new employment opportunities. We sell 200 specialty pigs each and every week, come rain, snow, or national holiday, offering distribution and sales services to American farmers who comply with our standards on genetics and husbandry protocols.
This past year, the Hearst Ranch in California and S. Wallace Edwards and Sons in Virginia allowed us to accomplish major infrastructure changes in our distribution network, thus reducing prices for over 30,000 mail order clients. In the summer of 2011 we will again sell eighth cattle from the Hearst Ranch, the largest grassfed cattle operation in the United States. Sam Edwards is for the fourth year producing European quality prosciutto style hams, from Heritage breed pigs including some raised on peanuts, milk and cranberries.
Perhaps the greatest accomplishments of 2010 has been the growth of HeritageRadioNetwork.com (HRN), a media outlet located in the back garden of Roberta's Restaurant in Brooklyn, NY. HRN was inspired by Carlo Petrini's radio station of the 1970s, Radio Bra Onde Rosse. Led by Executive Producer Jack Inslee, HRN offers programming on our food supply and environment, with guest appearances from the top echelon of talent from multiple disciplines. At years end, we count 21 weekly shows on our Network, which saw its birth in April of 2009. Our newest show, Speakeasy, will focus on the history of the American cocktail hosted by Damon Boelte, bartender at Prime Meats.
Other shows include Dave Arnold's Cooking Issues which discusses new and innovative techniques, equipment, and ingredients, Beer Sessions, an exploration of craft beers from around the world, and Michael Harlan Turkell's, The Food Seen: a nexus of art, photography and the culinary scene. No broadband or internet radio commands the nitty-gritty of food issues, interests, or market trends that HRN routinely explores. Our shows go literally from farm to table, and art to architecture. What's even more impressive is that these shows broadcast weekly thanks to the selfless investment of our hosts and guests who welcome the opportunity to offer more than a three-minute sound byte while investigating complex issues. Discussions are in depth, and totally different from the typical radio experience. HRN is designed as a search engine: just type in a word and find every time it has been tagged as a theme.
We are immensely proud of our staff, our farmers and our radio partners. We will continue to work hard to meet the challenges that lie ahead in our next decade. For more information please contact us at 718-389-0985, email@example.com or email@example.com.

ATLANTA -- After beating up on an FCS team (Western Carolina) and a Sun Belt Conference team (Middle Tennessee State) in its first two games, Saturday's game against Big 12 member Kansas was supposed to be Georgia Tech's first real test of the 2011 season.
Based on the results, consider that test passed with flying colors, particularly the Yellow Jackets' offense, which piled up a school-record 768 yards of total offense to avenge last year's embarrassing loss to the Jayhawks, with a 66-24 victory Saturday before 42,025 fans at Bobby Dodd Stadium.
"I was really proud of our guys," Tech coach Paul Johnson said. "I think they came out in the third quarter and asserted themselves the way we should have.
"A lot of big plays. The skill guys, the A-backs, had a big day. It was fun. Especially after last year, it was fun."
Orwin Smith was the biggest hammer wielded by the Jackets (3-0) and put up ridiculous numbers on the day by amassing 317 all-purpose yards and scoring two touchdowns for the Yellow Jackets.
The 6-foot, 202-pound junior ran for 157 yards on just five carries, caught two passes for 108 more yards and rolled up 49 return yards.
"I'm just doing the same thing I've been doing -- just trying to get better," Smith said. "I feel personally, if I can get better, I can make the team better. And I think everyone should feel that way."
But Smith's numbers weren't the only eye-popping figures for Tech on the day.
Among the Jackets' record yardage total were six scoring plays of 19 yards or more, including four of 52 yards or more, 621 yards on the ground -- including 110 from Embry Peeples and a combine 143 from Roddy Jones and David Sims -- and 196 yards of total offense from quarterback Tevin Washington.
And while the offense was rambling, the defense was wrecking -- at least, in the second half, when Kansas was held to just 116 yards and seven points.
"We tackled better, and I think we played some dime (package)," Johnson said of the difference in the defense in the second half. "But I think the guys just kind of turned it up a notch. I don't think we did a whole lot (different)."
The defense needed a boost after the closing seconds of the first half, when Kansas drove 65 yards in just 37 seconds before Alex Mueller's 28-yard field goal with 2 seconds left sent the Jackets into intermission with just a 24-17 lead.
That quick strike ended a half in which the Jayhawks rolled up 246 yard of their own, including 141 by quarterback Jordan Webb on 9 of 13 passing.
But the Tech offense gave the defense that momentum it needed early in the second half.
A 29-yard return by Smith set up another long burst from his fellow A-back Peeples -- this time, a 63-yard scoring run off an option pitch -- to push the Jackets' lead back to two possessions at 31-17.
"It was momentum," junior cornerback Rod Sweeting, who posted six combined tackles and assists, including one for a loss, on the day, said of the quick score in the third quarter. "It got the crowd (back) into it, and we fed off their energy."
The defense used that energy to its advantage, holding Kansas (2-1) to only a touchdown that came against Tech's reserves with just 2:24 to play with the outcome no longer in doubt.
And the offense continued to build even more energy, following a pair of defensive stops with Washington hooking up with Smith on a 67-yard scoring strike and Jones on a 52-yard TD completion to balloon the lead to 45-17 with 6:55 left in the third quarter.
The only question after that was how high Tech's offensive total would reach.
The Jackets didn't quite get to the 800 mark that the student section kept calling for late, but it was still a satisfying afternoon, especially in the wake of last year's 28-25 loss in Lawrence, Kan., that in some ways defined Tech's 6-7 season.
"They beat us last year, so I guess they thought coming off the win, they could stop us again," said Washington, who was 4 of 7 for 164 yards and two TDs. "I definitely don't think we were as prepared to go out and play (last year). coming into this year, we wanted to make sure we were ready to play.
The Jackets seemed quite ready to play from the onset.
For the third straight game, Tech's offense got started with a bang.
On its first play from scrimmage after taking a punt from his own 5-yard line, Smith swept around the right end, took advantage of a big block by right tackle Phil Smith to break free and followed another block by receiver Tyler Melton downfield to finish off a 95-yard touchdown run.
It was the longest run in Tech history, breaking the old record of 88 yards by Jonathan Dwyer just three years ago.
It also marked the third straight game the Jackets scored on their first snap of the game, and gave them a 7-0 lead just 2:27 after the opening kickoff.
The score turned out to be just the opening salvo in the Jackets offensive assault.

The decisive signal
With the aid of the mouse-ear cress (Arabidopsis thaliana), a frequently used model plant, Ive De Smet and Valya Vassileva in Tom Beeckman's group have been studying how a plant determines which cells will trigger offshoots. To do this, the VIB researchers in Ghent have employed a special technology that makes it possible to make synchronous offshoots develop at different moments. This allowed them to isolate the cells that induce the formation of offshoots. They found out which genes are active in these cells and compared them with the genes that are crucial to normal cell division. In this way, the researchers identified a specific set of genes that control asymmetric cell division and send the signal for the formation of offshoots.
ACR4: control over asymmetric division
The researchers then examined one of these genes more closely. The ACR4 gene contains the DNA code for a receptor, a protein that is often located on the exterior of a cell to pick up signals from the outside and transmit them to the controlling mechanisms within the cell. When the researchers disrupted the function of ACR4 in plant cells, the precisely orchestrated asymmetric cell division was also disturbed. From this finding, De Smet and Vassileva inferred that ACR4 plays a key role in the creation of offshoots. Because the protein has a receptor function, triggering the formation of offshoots depends on its reaction to signals from the environment.

California was rain. At turns soft and steady and other times torrential, filling the concave places curbside with wide lakes the color of coffee, to be splashed at unsuspecting passer-by as cars churned passed.California was palm trees and bougainvilleas and trumpet flowers and a wild abundance of deciduous trees still with golden leaves even in early December, the sidewalks strewn with flecks of yellow like so many fallen stars. It was a trip on the tail-end of the stomach flu; it was dizziness at the airports and sleeping in uncomfortable positions on the plane, and all of it was worth it to see my dearest friends with new babies, and to do a reading in a beautiful loft, celebrating my book with the people who knew me when I was who I was then: a California girl, back in high school, with windy hair and a crooked-toothed smile.
I hadn't seen some of them in 16 years, but seeing them again felt familiar in the way riding a bike is familiar after not riding for years. You just know. You remember. There is body memory to the hugs; and a timber and depth to the laughter. It was the first time, really, that I felt myself reveling, a little bit, in the accomplishment of writing a book. It was a lovely way to wind the season down: seeing my book in the hands of friends and loved ones.
And now I'm back, with rain here too at the end of this dirt road. The warmest winter we've had here in my memory; the ground still soft and the air sweet with decomposing leaves and ozone as the wind blows in and the clouds lift, revealing the cerulean bowl above. In the morning, the boys run down the hall to find what the Advent Fairy has brought. She slips into our house on fairy wings, bringing special notes and tiny gifts; and after dinner the boys write loving notes to her: Bean, with uneven printing and phonetically spelling and a zillion questions about her wings and adventures and magical names; and Sprout, who has just learned to write the letters of his name, practices them gleefully on snippets of colored construction paper that he carefully cuts.
There are just a handful of days really; two weeks exactly before we slip away again for a holiday adventure as a family. And between now and then a hundred things, the least of which is laundry–though it's taking over our lives. I can't remember the last time it was all folded and put away; still every night we have dinner together and over shrimp tacos with lime and mango, T and I laugh and listen and map our future–here, and then somewhere beyond here–and then the laundry doesn't really matter at all. Instead what matters is going to bed early, the warm coffee-colored fur of the dog against my hand, silverware standing like soldiers in tidy rows in the dishwasher to be cleaned, and plotting creative collaborations with friends. Here's a peak at some new work. Nothing makes me happier lately than having a brush in my hand.
How have you been? What does this time of year look like for you?
Working on illustrations for the book. Mixed media collage + digital + graphite sketches.
Also: A midsummer migrane; cicadas singing into late evening.; trying to remember to drink enough water + follow garment care instructions for washing; wishing for decompression; wrapping up projects for the summer semester; singing songs to Sprout until he falls asleep in my arms (a rare occasion for us both.)
It has been stormy the past few days: dark skies, fierce winds, rain at the slightest suggestion, then tempestuous blue skies all over again, and this, friends, is where I am at too.
Earlier this week I got news that financial aid for school may be a question and it's such a complex situation, our lives, our finances, the lot of it…and so here I am again, in limbo, opening my heart up wide to the universe.
I want to trust, to believe that all will be as it should; that things will align and fall into place. But oh, must it be this intense, this tenuous, this thinly threaded? Must everything come like the rains, abrupt and last minute, tearing down dead branches, and leaving everything rinsed and and astounded and green? This seems the way now, that things unfold around here.
So. A little more wondering.
More fingers kept crossed.
More breath held.
It's their busy time in the financial aid office, and so I don't get my answers any faster than anyone else gets theirs. Seven to ten days, more or less. Damn.
Will you cross your fingers for me?
PS: I hardly have the words, for grinning, at how all your lovely offers for my art made me feel. THANK YOU. I'll be shipping the pieces tomorrow–and enjoying more space in my studio to create new things.
It's been twenty days since I launched A Field Guide To Now, and in those twenty days I have been more intensely creative than I've been in over a year.
I've been forced way outside my comfort zone. My word for the year was action, and this project has forced me to take action on behalf of my career as a writer and artist in ways I couldn't have conceived of when I first took the plunge. I've had to learn how to query and research and push the limits of my ability to create at night after small boys go to sleep. I'm working on this book project, my novel, paintings, and a few other big projects that are under wraps with fingers crossed.
(I am also working part time, at a job that is pushing me to learn In Design and Photoshop, always under deadline. The child-free hours of my day are spent thusly: designing ads and view books and writing press releases. The rest of my day is spent juggling, with a single-minded focus pounding in my head like jungle drums.)
I am compelled, determined, wired, moody, thrilled, exhausted, inspired. When I sleep my mind is active in a way that is almost new to me. It's frenetic and repetitive: gnawing away at the creative tasks I've left off from before bed. This past week I've begun dreaming of whales—and they've inspired some of the newest art for A Field Guide To Now. Here is a glimpse (in progress.)
Incidentally, when I looked up what it means to dream about whales, this is what I found: Whale reintroduces us to our creative and intuitive energies to show us a talent we've forgotten about or haven't been aware existed. How spot-on is that?
I've had more coffee and less sleep; more wine, more sex, more dreams and less rhythm. I'm spending less time on laundry and dishes (and the house is in probable shambles because of it) and more time perched on the stool in my studio painting, with gauche on my fingers. Less time taking leisurely walks with my boys; more time trying to multi-task while they're under foot.
It's made me think about my identity, about who I am and how I define that. For a while, after Sprout was born, I slipped wholly into the identity of mother, and felt my world narrow to the small, domestic orbit of that life. It was restful, to be there. For a while. Sprout was such an easy baby that I enjoyed his babyhood in a way that I never fully did with Bean—who cried more and was more needy, just as I was newer and more anxious at the whole mommy thing.
But now, Sprout is walking. Bean is 5. The house is littered with legos (Sprout holds lego helmets in his mouth like a chipmunk. I've checked his diaper but he's never actually swallowed one. Go ahead call me neglectful. YOU just try to keep legos off the floor with two boys in the house, four years apart.) There is a constant stampede of activity and peanut butter sandwiches and glasses of milk that get spilled. The vacuum is out all day long. Money is tight. Bean has outgrown all his pajamas. Sprout is starting to say words.
And in the midst of all this messy, simple, regular domesticity, I've begun to long fiercely for myself. For myself not as a mother, but as someone entirely separate from my children.
Truthfully, I've always had an uneasy relationship with the definition of motherhood, and now, more than ever, I am enjoying my boys and wanting to be distinct from them, in my own right. A writer. An artist. Right now my mind is preoccupied with the craft of writing, with images, and also about self-doubt, and longing…
How do you define yourself? Where does your definition of motherhood (if you are, or want to be a mother) shape you? What are the words you use to tell yourself the story about your life as it is at this current moment?
I did it. Days of mapping out details and collecting information and editing video clips (whoa, no small thing!) and finally, here it is. A Field Guide To Now.
It kind of feels like giving birth. A lot like it in fact: the risk, the unknown, the realization that it's all beyond my control even though I'm going to give it every single thing I've got.
It's the first time I've ever taken a leap like this. Plunged with a fluttering heart towards a dream.
Please support this.*
And also: I have two birthday boys this week! Bean's birthday is the 16th and Sprouts four days after. This is the week that has changed my life, twice, momentously. It felt so utterly right to launch this project today. (Still. I'm nervous.)
*Things are tenuous financially, and this would make a huge difference. Please Share this project with everyone you know.

Transnational educational spaces: The transformation of HE in Hong Kong and the new (im)mobilities of Chinese students
Dr Johanna Waters, Department of Geography, University of Liverpool
Wednesday 02 June 2010, 1300-1400
LEC Training Room 1
Society and Environment Research Theme Seminar
The last 10 years have seen the deepening and expansion of the process of internationalisation in relation to higher education (HE). There are many different aspects to this, including the proliferation of language schools catering to international students, "satellite" university campuses, distance- or e-learning, international MBA programmes, and the development of national education "brands". Governments and HE institutions are becoming increasingly entrepreneurial when it comes to promoting their educational "products" overseas. The international mobility of tertiary-level students is one of the more conspicuous elements of internationalisation in relation to HE. In this seminar, I draw upon the preliminary findings of a research project (funded by the ESRC and RGC in Hong Kong and conducted jointly with Dr Maggi Leung at the University of Hong Kong) examining another facet of internationalisation - the increasing overseas presence of UK higher education institutions (HEIs) in East Asia. More specifically, I consider here the experiences of students in Hong Kong undertaking 'British' degree programmes (in situ). I discuss their decision-making around attaining a British degree, their experiences of their programme to date, and their plans on completion of their degree. Conceptually, the project considers the relationship between international higher education and (im)mobility. Transnational educational programmes of the kind reported here ostensibly undermine the assumed relationship between overseas education and international travel. In this study, we examine the extent to which physical mobility is integral to the experience of international education.
Biography: Johanna is a lecturer in human geography at the University of Liverpool whose research specializes in the the internationalisation of education and on issues of education and mobility, as well as transnational migration and the experience of immigrants in different countries. In the past she has undertaken extensive research for the B.C. Ministry of Multiculturalism and Immigration in Canada. She is currently undertaking research funded by the British Academy and ESRC-RGC grants on the experiences of students in Hong-Kong taking "British" degree programs and the implications of this, which will be the subject of this seminar.

The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.
The present invention relates to a method and apparatus for the measuring of power and current flowing through transmission lines, and of the power generation or consumption of a facility.
As the traditional monopolies of electric utilities have been relaxed in the United States, there has developed a growing market in wholesale electric energy. Utilities, independent power producers, and power marketers are some of the participants in this volatile market. Among other variables, such as time of day and year, and temperature, electricity pricing in a given region is dependent on the operational status of the electric generation and use facilities in that region, and the transmission capacity of critical transmission paths.
Participants in the electric power markets, accordingly, would find real-time information on the operational status of important generation, use, and transmission facilities in a region to be useful in developing trading strategies and responses to power system events. Likewise, relaxation of the monopoly status of traditional utilities has resulted in increased competition for customers amongst suppliers of electric energy. Information on the electric power use of potential customers would be useful to those involved in bidding for electricity supply contracts. It would be further advantageous to determine information on the supply and demand of electric energy without having to directly connect to the transmission and distribution lines conducting electric energy.
It is, therefore, an object of the present invention to provide a methodology whereby real-time information on transmission line power flow, generation facility power output, substation power input and output, and facility power use may be obtained remotely and transmitted to an end-user of such information. It is also an object of this invention to provide an apparatus capable of accomplishing this task It is a further object of this invention to collect and provide this information accurately, regardless of changing environmental conditions, over the long-term, and with a minimum of human involvement. Furthermore, it is an object of this invention to provide this information to an end-user in such a form as to permit the end-user to act in a logical and timely fashion to real-time events on the power system.
Towards the accomplishment of these objects, disclosed is a method for determining in real-time the net electric power and current either generated or consumed by a facility or substation, and the electric power and current transported by an electric transmission line. This is accomplished, in part, through the use of one or more apparatuses for monitoring the magnitude and direction of electric power or current flow in a single electric current carrying conductor or in multiple current carrying conductors operating in a poly-phase arrangement. The present invention thus relates generally to a method and apparatus for the long-term, real-time, remote monitoring of the electric power and current flow to, from, or in a monitored facility.
For the purpose of the following discussion, the terms "transmission line" and "electrical line" will generally refer to a set of at least three conductors operated in a poly-phase arrangement for the purpose of transmitting electric energy. Each of the three conductors comprising the transmission line is energized with a sinusoidal voltage 120 degrees out of phase with the other two conductors comprising the transmission line. "Bundled" conductors, which consist of multiple wires in close proximity to one another that are operated electrically in parallel, will be referred to and treated as a single conductor.
Current and power monitoring according to the present invention may be accomplished by placing one or more of the apparatuses described herein in proximity to each of the electrical transmission lines that provide service to a monitored facility. Generally, it is desired that an apparatus be located within approximately 200 feet of the monitored line, though the actual location of the apparatus is dependent on terrain, line geometry, and other factors unique to the particular line. It is to be understood that the present invention may be used to measure characteristics from single or multiple lines, instead of a facility.
Each individual apparatus transduces magnetic fields emanating from the monitored power line and determines the phase relationship to another signal that is synchronized to power system frequency. This signal, in an exemplary embodiment, may be the electric field emanating from the monitored line. It may also be a measure of the voltage derived from some electrical connection to the power system such as that obtained from an electrical wall outlet. By this synchronization, a measure of the direction of current flow in the line is determined. Because any given distribution or transmission line is operated at near uniform voltage, a measure of the current flow in a line is also a measure of the complex power flow in the line. The power flow can be divided into its real and reactive components through use of the phase angle relationship between the monitored magnetic fields and the synchronized signal.
Standard transmission or distribution lines typically consist of at least three current carrying conductors. Multiple monitoring devices devoted to each line may give increased sensitivity in determining the current flow in the individual conductors using methods such as that described in U.S. Pat. No. 5,438,256, the disclosure of which is hereby incorporated by reference. However, because the method of operation of most transmission lines is predictable, it is possible to monitor a single poly-phase line with a single apparatus, as disclosed herein. Furthermore, multiple poly-phase circuits that are carried on the same transmission structure may be individually monitored using the apparatus and methods disclosed herein.
In an exemplary embodiment of the present invention, magnetic fields may be transduced either through the use of coil probes or Hall effect sensors. Electric fields may be transduced through the use of a free-body meter, or a ground-reference type meter, as described in IEEE Standard 644-1994.
After transduction, signals representing the electric and magnetic field strength may be magnified and filtered. The magnitudes and relative phase angles of these signals are then converted to digital signals, evaluated, and, in an exemplary embodiment, stored by use of a microcontroller or microprocessor, at least one analog to digital (A/D) converter, and digital memory. The microprocessor may be programmed to analyze and record the data received through the A/D converter.
Included in an exemplary embodiment of the apparatus according to the present invention is a device that permits communication between the remote apparatus and a central computing facility. This communication device may comprise, for example, a cellular telephone and modem connected to the microcontroller. Similarly, a radio-frequency, or microwave connection may be made between the apparatus and the central computing facility. Satellite communication between the apparatus and the computing facility is also realizable. Algorithms in the microcontroller determine when and if the apparatus should communicate with the central computing facility, or provide some other form of communication, such as an event-notification alarm, directly to an end-user.
Where environmental concerns exist, the apparatus may include an enclosure that protects the components of the apparatus from the elements. This enclosure may be constructed of material that will not interfere with the strength or the measurement of electric or magnetic fields, such as wood, fiberglass, plastic, or the like. Likewise, if low temperatures are likely to interfere with proper operation of the apparatus, a heating element may be included in the enclosure. The apparatus may be battery powered and may include a solar charger to permit long-term, unattended operation
The central computing facility may be comprised of a digital computer such as a typical PC and at least one communications device. The central computing facility receives communications from all of the remote apparatuses monitoring a facility, facilities, line, or lines under measurement. The data received from the apparatuses is processed to determine the magnitude and direction of current and power flow in each monitored line. The net power and current flow into or out of the facility may then be calculated as the sum of the individual line flows. Once computed, the net facility power-use or generation, as well as the power and current flows in individual lines can be transmitted in a secured fashion to the end-user. This communication could be made via a direct computer-computer connection, a digital pager, Internet, LAN, WAN, or the like. The central computing facility may provide additional communications such as event-notification-alarms after the recorded data has been analyzed and found to meet certain prescribed conditions.
In a broad aspect, the present invention may include an apparatus for remotely measuring current in an electrical line (or lines) comprising: a magnetic transducer to convert the magnetic field of the current at a remote location, into a magnetically transduced signal; and a first conditioning circuitry coupled to the magnetic transducer to prepare the magnetically transduced signal for analysis. In an exemplary embodiment, the conditioning circuitry may include some or all of the following elements: an amplifier(s); a filter(s), a rectifier(s), all of which may be serially coupled. Of course, multiple apparatuses may be used to measure a plurality of lines.
In exemplary embodiments, the apparatus may also include an electrical transducer to convert the electric field of the line at the remote location into a reference signal; and second conditioning circuitry coupled to the electrical transducer to prepare the reference signal for analysis. Alternately, the reference signal may be synchronized to a frequency of a power system connected to the line. Also, the present invention may include one or more measuring circuits coupled to the conditioning circuits to evaluate magnitude of the magnetically transduced signal and/or phase angle between the magnetic field and reference signal.
Further, an apparatus according to the present invention may include additional elements, including a data storage device to store data, one or more communication devices to transmit the data to a central facility (for processing, maintenance, or further distribution) and/or end users. In exemplary embodiments, the magnetic transducer may comprise a coil probe or a Hall effect sensor, and the electrical transducer may comprise a free-body meter or a ground-reference meter.
Another broad aspect of the present invention includes a method for remotely measuring current in an electrical line (or lines), comprising the steps of placing one or more apparatuses including a magnetic transducer in proximity to the line; receiving magnetic field emanating from the electrical line with the magnetic transducer; and processing the magnetic field to determine a magnitude of the current. Data representative of the magnetic field may be relayed to a central station for some or all of the processing. Further, information representative of the current (i.e., magnitude and/or direction) may be transmitted (via different mediums including, fax, computer, modem, Internet, LAN, WAN, or the like) to an end user.
In addition to the magnetic field, an electrical signal synchronized to a frequency of a power system connected to the line (which may be an electric field emanating from the line, or it may be obtained from a wall outlet), for example) may be received and used to determine a phase angle between the magnetic field and the electrical signal to ascertain the current's direction.
In certain embodiments, the line may be coupled to a facility, and the information informs the end user of power consumption or power generation of the facility (including net current power flow in a plurality of lines connected thereto).
It has only been recently that there have developed markets for the wholesale trading of electric energy. The power marketers, independent power producers, and others who participate in this market are finding that transmission line loading and the operational status of electric generation and use facilities in a region are important in determining the price and quantity of electricity traded in a region. Access to such information is limited. Utilities operating power systems have always required precise knowledge of transmission line current and power flows, and facility power usage or generation in order to best operate the power system. These utilities have access to the conductors comprising the transmission lines and the equipment to which they are connected. Consequently, systems have been developed that attach directly to electrical line conductors and measure very precisely the current and power how in the conductor. However, generally, the information from these systems is withheld from market participants.
Because the electric power markets are dependent on the physical status of important facilities and lines, there is a clear market need for the collection and dissemination of operational information regarding said lines and facilities. One of the objects of the present invention is to provide a system to allow the collection and transmission of such information to market participants without connecting to the utility system or requiring the placement of equipment in utility right-of-ways or easements. The present invention accomplishes this by disclosing an apparatus that may be located a distance from a transmission line under surveillance to be used to measure remotely the current or power flow. The method by which information from such an apparatus is used to determine the transmission line current is also disclosed. Additionally, the present invention describes a method for using such information to determine the net power generation or use (or current flow) to or from a monitored facility. All of this information is collected in an automated way that allows for a minimum of required human intervention and is thus well-suited for the long-term, real-time collection of information desired by power market participants. The information may be centrally collected, processed, and then sent in a useful form to a plurality of market participants.
Given the ease of computer to computer communications and the familiarity that market participants already have with computer based information systems, such information may be sent via the Internet, or a LAN, WAN, or the like, to a computer where such information could be displayed to an end-user. The end-user could choose to dedicate a computer monitor or monitors to the display of such information. The system may allow the end-user to view a graph of the power and current flow in a particular transmission line, or set of transmission lines. Similarly, the system may allow the end-user to monitor a graph of the flow of power into or out of a monitored facility or facilities. Such information could be viewed as the information is updated. The system may also provide the end-user a "snap-shot" view of the operational status of lines or facilities at a single moment in time. Information may be stored so that historical patterns and trends could be used to develop trading strategies.
Events, such as the outage of a generation, transmission, or use facility, unexpected or otherwise, may be highlighted to the end-user through the use of event notification alarms sent either from the central computing facility, or directly from the distributed monitors. A transmission line reaching its operational limits might also result in an alarm. Such alarms could consist of computerized audible and/or visual warning on the dedicated monitor(s). Additionally, warnings could be sent to a pager or telephone. The alarms could inform the end-user of the date, time and nature of the event.
Information updates to the end-user may be dependent on the transmission of data from the distributed monitors to the central computing facility. Data from an individual monitor may be sent either continuously or after a fixed amount of time has transpired since the last data transmission. Additionally, the monitor may be programmed to transmit data when other conditions are met such as a rapid change in the collected data or the penetration of some threshold. For example, the monitor might immediately transmit data when this data falls below a threshold value suggestive of a transmission line outage. The data may also be processed by the central computing facility to immediately transmit the location and nature of the event and its significance to the end-user, allowing the end-user to act on this knowledge in a timely fashion. Likewise, the end-user may have the option of requesting information from a particular monitor or set of monitors.
Through the use of state-estimation techniques, the power flow information collected by multiple monitoring apparatuses may be used to predict or estimate the power flow, generation, or consumption in other parts of the power system not directly monitored by these apparatuses. State-estimation is a mathematical process and may be performed at the central computing facility. The results can then be transmitted to an end-user of this information. An apparatus in accord with the present invention may also be used to measure, at a given location from a line, the strength of the magnetic field emanating from the line. Such information may be useful, as long-term exposure to magnetic fields may raise health concerns.
Referring to FIG 3, there is shown a facility, 10, whose electric power generation or use is to be monitored. In typical uses of the present invention, facility 10 may be an electric generation plant, manufacturing plant, office building, substation or any other power consuming or generating environment This facility is connected to the electric power system 15, by electrical transmission (or distribution) lines 11 and 12. Lines 11 and 12 provide electrical service, typically at 60 Hz. The power system 15 consists of the network of electrical conductors, loads, and generators connected to provide or utilize electrical service in a region. Generally each transmission line will be comprised of three separate conductors, the voltage of each varying sinusoidally at the same, or nearly the same, peak value. The voltage between each conductor and ground differs by 120 degrees (of power-line operating frequency) in phase from that of the other conductors. As discussed, the monitored facility 10 may either be consuming, generating electric power or both, though the net generation or consumption is to be monitored.
To perform the methods of the present invention, apparatuses according to the present invention, shown here as monitors 13 and 14, are placed in proximity to lines 11 and 12. Generally, these apparatuses will be placed within approximately 200 feet of the lines to be monitored. Specific placement is dependent on a number of factors unique to the particular line being monitored including line geometry, terrain and obstructions. For example, to monitor a line in a dense urban area, the apparatus may be located more closely to the line than if the monitored line were located in a field, free of obstructions that could interfere with the electromagnetic signals emanating from the line. It is desirable to place the apparatus in such a position that the power frequency signals transduced by the device can be certain to be derived from the monitored line. This generally means locating the device within a lateral distance of 100 feet, and more specifically 60 feet, of the monitored lines. The monitors 13 and 14 record information on the electromagnetic fields generated by the voltages and currents associated with the respective lines.
As discussed in more detail herein, monitors 13 and 14 each include a transducer (not shown in
The computing facility 16 processes data from monitors 13 and 14 and determines the flow of current and power in lines 11 and 12 by calculation. The computing facility 16 also determines, by calculation, the net flow of current and power into and out of the monitored facility 10. It is to be understood that in alternate embodiments, the processing may occur within the monitors themselves or by the end-user, thus obviating the need for a computing facility 16.
Using state-estimation techniques and the data from the monitors 13 and 14, the central computing facility 16 can also estimate power flows, generation and consumption at points on the power system 15 not specifically monitored by the apparatuses. Some, or all, of this information is then transmitted (as represented by data-flow 19) to the end-user of the information at location 20. The end-user includes anyone for whom information about the power flows in lines 11 or 12 or the net power use of facility 10 is useful. End-users may include, for example, power marketers, energy traders, energy producers, or energy consumers. It is to be understood, of course, that information may be provided to a plurality of end users or locations. Information is transmitted from central facility 16 to the end-user's location 20 via some form of communications equipment such as the Internet, modem and telephone, direct computer-computer connection, LAN, WAN, by modem and pager, or the like.
Power systems are operated at a fixed nominal frequency about which only small deviations in frequency are permitted. In the United States, this nominal frequency is 60 Hz. Discussion will be limited to currents and voltages at or near nominal power system frequency. It is also to be understood that the following discussion assumes that, at the monitor location, the transmission or distribution lines under surveillance are the principal source of power frequency magnetic and electric fields. Sensors are physically removed from other magnetic and electric field sources such as electrical power lines not under surveillance.
In order to understand the means by which current and power flow is calculated by the central facility 16 it is necessary to refer to
During steady-state operation, the electric fields emanating from the individual conductors vary sinusoidally at power frequency. At a given point in space, the net electric field is the vector sum of the electric fields generated by the conductors (and, as we shall see later, the conductor images) and is itself a sinusoid. During steady-state operation, the voltage magnitudes of the phase conductors to ground, and the phase difference between conductor voltages, vary only minimally. Thus, the net electric field at a point in space away from the monitored line can act as a fixed reference signal synchronized to power system frequency.
The net electric field generated by a transmission line at a point in space is computed as follows. A single conductor h meters over the earth is modeled electrically as a line charge of q coulombs/meter with an image line charge located h meters beneath the earth with charge −q coulombs/meter. The relationship between conductor voltage to ground (Vag) and line charge is given in EQ. 1,
All measurements of distance in EQ. 2 and following are made in the plane normal to the transmission line.
In matrix form, the voltage-charge relationship between all conductors is,
Alternatively, EQ. 3 can be written more simply as
EQ. 6 yields a phasor representing the sinusoidal variation of electric field at the point in space f (labeled 143 in
Thus, it is possible, given the spatial geometry of the line, the phase relationship of the conductors, and the voltage magnitude at which the line is operated to calculate the net electric field generated by the line at a general point in space. For instances where ground lines or other conductors are present, the process for solving electric field is the same. The order of the matrices increases accordingly. Large objects such as trees, transmission line structures, and fences affect electric field magnitude and phase angle. Thus, if it is important that the above equations accurately predict electric field magnitude and phase angle, care should be taken to make such measurements away from such objects.
Likewise, the current flowing in each conductor generates a magnetic field related to the magnitude of current flow. The net magnetic field at power frequency at a specific point in space is a function of the line geometry, the relative position of the point in question to the line, and the magnitude and phase angle relationships of the currents in the overhead conductors.
Specifically, the magnetic field emanating from a single transmission line can be computed as follows. A current I conducted by a long straight wire generates magnetic flux density, {overscore (B)}f, at a point f distance ρ meters, from the wire according to EQ. 7.
When solving for the net magnetic field generated by a set of multiple current carrying conductors, it is possible to account for the return currents associated with the overhead conductor currents using the method of complex images. The image distances, however, are usually located on the order of hundreds of meters beneath the ground plane and thus contribute negligibly to the magnetic field strength near most lines. The principle of superposition applies to the computation of the magnetic field resulting from a transmission line. Thus, neglecting the return currents, the magnetic flux density at a point f resulting from current flows in the multiple overhead conductors depicted in
Typically, the currents Īx of EQ. 8 are sinusoids. It is customary to perform the arithmetic of EQ. 8 using phasor representations of the currents. Thus, the magnetic flux density is computed to be a time varying sinusoid. Magnetic flux density is also a vector quantity. It is desirable to operate the line in a "balanced" fashion, in which, at power frequency, the currents in each of the conductors are nearly equal in magnitude and vary is in phase by 120 degrees from the others. Assuming balanced operation, EQ. 8 reduces to EQ. 9.
In the case where a single transmission line is the source of magnetic field, the measurement of magnetic field at a single location (and in a single orientation) can be used in conjunction with EQ. 9 to solve for current flow in the line. Precise measurements of the relative positions of the conductors comprising the line and the position of magnetic field measurement are required and can be obtained with a measuring tape, and transit. The measurement of magnetic field may be accomplished through the use of a single coil probe oriented in a known direction relative to the transmission line.
When two different transmission lines, transmission line 1 and transmission line 2, are in close proximity to one another, such as is the case when a single transmission structure supports two different lines, the relationship between transmission line currents and magnetic fields is described by EQ. 10,
In general, the monitoring of n lines will require n magnetic field sensors. A single electric field sensor may act as a synchronized phase angle reference to all distributed magnetic field sensors. In the case of a single tower supporting two different transmission lines, it is possible to locate the two magnetic field sensors on opposite sides of the tower. The two sensors may be attached to one of the exemplary apparatuses described herein, or two different apparatuses may be employed to make the measurements. In the instance where only one apparatus is used with multiple probes, the probes may be directly connected electrically to the apparatus or a radio-frequency, microwave, optic, or some other such link could transmit magnetic field data from the sensor to the apparatus. Similarly, two orthogonally oriented coil probes located in roughly the same position could be directly attached to a single apparatus to provide the required magnetic field data.
For the case of two transmission lines in close proximity to one another, the current flow in each of the lines is determined by simultaneous solution of EQ. 10 at the two locations occupied by and in the two orientations of the magnetic field sensors. This requires precise knowledge of the position of the conductors comprising the transmission lines and the location of the sensors. These locations are determined using equipment that may include a range-finder, measuring tape, and transit. Knowledge of the phase angle relationships amongst the various conductor voltages and amongst the line currents is also required. These relationships are referred to as phasing.
In the following discussion the ground beneath the transmission line in the plane perpendicular to the path of the line is assumed to be flat. Vertical magnetic field refers to the component of magnetic field perpendicular to the ground. Horizontal magnetic field refers to the component of magnetic field parallel to ground and perpendicular to the path of the transmission line.
Thus, the current magnitudes and phase angle relationships to conductor voltages are determined. If the phase angle between line current and voltage is not desired, the process above can be stopped after Step 7 and a would yield a measure of the current magnitudes and phasing, and phase angle between the two transmission line currents.
The same process may be followed for the case where a single transmission line is the source of electric and magnetic fields. In this case, Steps 4 and 6 assume only one line is the source of fields. In this case, the preceding steps could be followed to determine the current flow in the transmission line at a particular instant in time, Īi, and EQ. 12 used to relate subsequent measurements of magnetic field to line current.
In the case of a single transmission line, phasing is not important in determining the magnitude of current flow. Consequently, if the magnitude of current flow is all that is desired, Step 1 and the PhFind program may be used to determine the magnitude of transmission line current. The magnitudes of both sides of EQ. 12 could be equated and the resulting equation would relate subsequent measurements of magnetic field magnitude to current magnitude. For the single line case, the phase angle between current magnetic and electric field, in the absence of electromagnetic disturbances external to the transmission line, varies in a one-to-one relationship with the phase angle relationship between conductor current and conductor voltage to ground.
As stated earlier, for the case where two transmission lines are the sources of electric and magnetic fields, two simultaneous measurements of magnetic field are required to compute the current in the transmission lines. These measurements can be made by two sensors attached to one of the exemplary apparatuses described herein, or by two different exemplary apparatuses placed in the vicinity of the lines. The sensors or devices are placed in different, known locations relative to the transmission lines. The monitors, as will be detailed later, give measures of the magnitude of magnetic field and the angle by which magnetic field leads electric field at the probe position. EQ. 13 relates the relationship between measurements recorded by the monitor(s) and transmission line currents.
The calibration constants C1, C2 are determined from EQ. 13 after first computing the constants α, β, and the conductor currents I1, and I2 from the process described in Steps 1–8. Henceforth, the line currents are determined from EQ. 12 and subsequent measurements of magnetic field S1 and S2. If the phase angle between conductor current and line to ground voltage was not obtained from Steps 1–8 an approximation of transmission line currents may be obtained. Assuming a value of the phase angle between transmission line current 1 and conductor voltage, and then advancing the second transmission line current by θ as determined in Step 7 allows the solution of EQ. 13 for currents as before.

The electrical power dynamics of a facility refer to the flow or flows of current or power into or out of a facility. This flow or these flows may be in one or more electrical lines connecting the facility to the power system that supplies electric service to the facility. The term may also refer to the net flows into or out of the facility amongst any combination of lines supplying electrical service to the facility. The central computing facility may perform the computation of the electrical power dynamics from the data transmitted from the distributed apparatus or apparatuses.

In an exemplary embodiment, this voltage may then be conditioned for analysis by appropriate conditioning circuitry. Specifically, in the embodiment shown in
In an exemplary embodiment, the microcontroller 34 may be a Motorola MC68HC11 microcontroller. Other suitable microcontrollers might include the Motorola MC68HC12, the Intel 8051 series, the Micromint PIC series, or the BASIC series from Parallax. The principal requirements of the microcontroller are that it sample and record signals and control a communications device to telemeter recorded data to the central computing facility. The microcontroller 34 is connected to the gain controls of the amplifier 24 via a pair of the output ports 31 of the microcontroller 34. Algorithms programmed into the microcontroller attempt to maintain the output voltage of the rectifier 27 between zero and five volts, a level compatible with the operational limits of the on-board analog-digital converter of the microcontroller.
The rectified signal from operational amplifier 27 is connected to an A/D converter (not shown in
In order to determine the phase relationship between conductor voltage and monitored conductor current, and the direction of current flow in the line, an electric field transducer 28 may also be included in the monitoring apparatus. Because electric field is related to the voltages on the conductors comprising the monitored line, and these voltages in steady-state operation vary little from their nominal values, the transduced electric field can provide, in the absence of other electric fields, a fixed reference signal synchronized to power system voltage. This transducer may be a free-body meter, or a ground-reference type meter, as defined in IEEE Standard 644–1994. A synchronized signal could be provided by a direct connection to some element of the power system such as could be accomplished through an opto-electronic link, a transformer, or a wire-to-wire connection to a wall outlet. Any such connection may provide a signal synchronized to power system frequency and would suffice as an input signal for this stage. In the exemplary embodiment, two parallel (to each other and ground), metallic, isolated plates vertically separated are used and the voltage between the plates 28 varies in proportion to the ambient electric field generated by the transmission or distribution line at the point in space occupied by the probe. In the exemplary embodiment, this signal is fed to a non-inverting operational amplifier 29 and then filtered by a low-pass op-amp based filter 30. The gain on the amplifier 29 may be set so as to generate a square wave from the electric field signal in order to aid in the detection of a voltage rise. A transistor based amplifier or buffer may replace amplifier 29 and filtering may not be necessary if the electric field probe does not pick up much high-frequency noise or if the electrical signal at the apparatus input from the probe is not noisy. From the filter, the electric field based signal is rectified by the op-amp-diode combination 50 and is sent to one of the on-board A/D converters (not shown) of the microcontroller 34. Further shown in
The microcontroller samples the analog inputs 25 and 26 representing the conditioned signals from the electric field and the magnetic field probes. Software programmed into the microcontroller waits for a voltage rise on the A/D converter connected to the signal from the electric field probe 26. A counter is begun that stops counting when a voltage rise is detected on the A/D converter that is connected to the conditioned magnetic field signal 25. This count is a measure of the phase angle difference between the magnetic and electric field probes. In the exemplary embodiment, this process is repeated a set number of times and the average phase angle difference between the signals from the magnetic and the electric field sensors is computed. An additional amplifier (not shown) may be attached in parallel between the rectifier 27 and another A/D converter (not shown) to convert the magnetic field signal to a square wave in order to aid in the detection of a voltage rise. In this case, two A/D converters would be required for the magnetic field signal, one to measure magnitude and the other to measure the time of voltage rise. Alternatively, the signals 25 and 26 may be fed to the input capture ports of the microcontroller 34 and a measure of phase angle determined using the microcontroller's internal clock.
As shown in
The entire system depicted in
Algorithms may be programmed into digital memory 32 to control the microprocessor 34 as follows. The microprocessor samples the time from the real-time clock 33 and records the time in digital memory 32. Subsequently, the microcontroller 34 samples the rectified voltage from the amplifier-diode combination 27, determining an average value of the waveform over several cycles. This measure is, likewise, stored in digital memory 32.
The microcontroller 34 then samples the conditioned electric field signal 26. This continues until the microcontroller 34 detects a rising voltage. A counter is started at this point. Subsequently, it begins to sample the conditioned magnetic field signal 25. When a rising voltage is detected, the counter is stopped. This process may be repeated several times and the average of the counter values is recorded in digital memory 32 as a measure of the phase angle difference between electric and magnetic field.
The microprocessor 34 then determines from the set of recorded values whether to power-up the communications equipment 36–38 and communicate the stored data The microprocessor 34 can choose to communicate its recorded data continuously, or it can be programmed to wait prescribed intervals of time between communications. Additionally, algorithms can be programmed into the microprocessor 34 to detect changes in the recorded values of magnetic field strength or phase angle relationship that result in a data transmission.
The real-time clock 33 also contains a set of programmable alarms. These alarms allow for algorithms that turn off power to the analog circuit elements 22–24, 27, 29, 30, and 50, and place the microcontroller in a minimum-power standby state, thus reducing power drain on the battery power system. The alarms in the real-time clock 33 periodically force the microprocessor 34 from its standby state into full-power operation. In this state, the system engages in the sampling and communication processes described above before returning to the minimum-power standby state. In an exemplary embodiment, the system alternates between minimum-power and full-power once every minutes.

Pegasystems late Thursday posted weaker than expected third quarter financial results – and also announced the coming departure of chief financial officer Craig Dynes.
For Q3, the business process management software company reported revenue of $101.7 million and profits of 13 cents a share; Street consensus had been $114 million and 19 cents.
The company noted that results were affected by "economic headwinds." Dynes said in a statement that economic conditions have resulted in "an extremely back-end loaded year with customers appearing to delay execution of large license agreements until the end of their budget period."
Dynes also said that he will leave the company following the filing of the 2012 10K, "ideally to work with a promising late stage private company."
In after-hours trading, PEGA fell $1.14, or 5.7%, to $19.

Control towers at 149 small airports to stay open
WASHINGTON (AP) -- The Federal Aviation Administration will keep open for now the 149 control towers at small airports that were slated to close as the result of governmentwide automatic spending cuts imposed by Congress, the Transportation Department said Friday.
The towers, which are operated by contractors for the FAA at low-traffic airports, had been scheduled to close June 15. They will now remain open at least through Sept. 30, the end of the federal budget year, the department said in a statement.
A bill hastily passed by Congress last month to end air traffic controller furloughs also makes enough money available to keep the towers open, the statement said. The bill gave the FAA authority to shift $253 million from accounts with unspent funds to keep controllers on the job. The furloughs at all FAA-operated airport towers and air traffic control facilities caused widespread flight delays across the country for nearly a week before Congress stepped in.

The first items that many individuals reach for when donating to a food drive or food pantry are canned or boxed non-perishable items. Now many community organizations in Berkshire County are reaching for shovels as a means to stretch donations and provide those in need with a source of nutritious, organic, locally-grown produce.
Each Tuesday morning the parking lot at the Berkshire Community Action Council (BCAC) springs to life as organizations arrive in pick-ups, vans, and sedans as a tractor trailer filled with food donations from The Food Bank of Western Massachusetts arrives. But, also waiting to be loaded into those waiting vehicles are over 600 pounds of fresh organic produce, harvested three hours earlier less than five miles away. Donations of cabbage, tomatoes, greens, carrots, potatoes, onions, and others make a surprising addition to the food sent out to pantries and allow the creative cooks at meal sites to add another dimension of nutrition to their meals.
Russell Moody, the minister at The Church of Christ in Pittsfield has created the "Giving Garden," A 200-by-80 foot organic garden proudly displayed on the rolling hill in front of their building. This is the first year for the Giving Garden. With an average weekly donation of 500 pounds the crop yield has peaked at nearly 800 pounds, all going directly to local food pantries and meal sites. The entire garden is supplemented and maintained through donated plants and 100 percent volunteer-driven harvests. Dozens of volunteered man-hours go into producing those 600-plus pounds of food each week.
The Church of Christ is not the only organization localizing food donations in Pittsfield. The Unitarian Universalists of Pittsfield also have a dedicated garden space, along with a mobile chicken coop to provide much needed protein to the local agencies. You can listen to the Unitarian Universalists Garden radio webcast, and find more information about the program here!
There are also community gardens popping up throughout the Berkshires. Schools, housing complexes, and little swaths of green space have been allocated for organic gardens with some or most of the harvest going directly to local food pantries and meal sites.
With fresh, organic produce speed is of foremost importance. On Monday August 20th, The Food Bank of Western Massachusetts received a large donation of organic eggplant. The produce was sorted and inspected at 9am Monday morning and later packaged and organized for shipment. On Tuesday morning The Food Bank's tractor trailer arrived at BCAC at 10:25am. By 12:30 as the First Methodist Church in Pittsfield is beginning to prepare it its Harvest Table meal for the evening, food pantry clients are choosing that very same eggplant that was donated to The Food Bank only one day earlier.
With so many new and exciting ideas to assist your local food pantry and The Food Bank of Western Massachusetts find out how you can donate in your community and fight hunger in your backyard.Comments Off

Quick Twitt | Bisping Has Substantial Amount of Weight to Cut | UFC News
UFC on FX 7 headliner, Michael Bisping shared via his Twitter today that he has started his weight cut (along with the help of a legal weight cutting aid) of twelve pounds in the wake of Saturday's middleweight main event against Vitor Belfort
Here is Bisping's tweet, asking for some much needed luck in making a healthy cut:
The UFC on FX 7 card takes place in Ibirapuera Arena in Sao Paulo, Brazil. With a win, Bisping has been promised a title shot against Anderson Silva.
The two middleweight superstars shared a heated exchange at today's press conference to promote the event. Belfort touched Bisping's face during a staredown to which Bisping responded with a slap to Belfort's arms and some choice words that we've come to expect from Bisping when his emotions are on high.
The two have been vocal adversaries of one another and things only worsened during the past few days of media coverage including at the open workouts when the fans got into the action.
Hopefully the weight cut leaves Bisping healthy enough to come in 100% tomorrow to level the playing field.
For the sake of his health and tomorrow's fantastic main event, I can speak for the whole BJPENN.com staff in wishing Bisping the best of luck in his weight cut.

pretty hard to cut weight when your that full of sh@t…lol
He is already making excuses for when he gets knocked out!
More like, he is going to beat the sh@t outa Belfort…lmao
Don't count out Belfort! I say if it stays standing I think Vitor will take the win.
i really think bisping takes this fight
I honestly don;t even know if Bisping wil make that cut. That is real tough on the body, and even if he does re hydrate he will have lost so much energy from the cut he will get mopped. I guess we will see….but he should have been more around 8 lbs off.
thats not a big cut for bisping. hes never failed to make wieght
That cut is barely more than I do as a distance runner (distance runners lose several pounds of sweat on large runs) I weigh 170, and often finish at 162. This is nothing; GSP sweats from 190…
I honestly see this fight being a letdown because Bisping will do to Belfort what he did to Stann and outwrestle him.
The tweet about the weight cut and everything is probably just a ploy.
WHAT?? Have any of you girls ever cut weight?? 12lbs is no le asi…
this isnt news, its just something bisping put on twitter.
