Do you have a quote that guides, inspires, or embodies your training/racing/life?
"Never, never, never give up." - Winston Churchill
Why do you run?
Running honestly makes me a better mother, wife, and friend - it focuses my brain, gives me confidence and helps me shed the stress in my life. Most of all I am happy when I run. I have never, ever finished a run less content than when I began.
What is your favorite place to run?
I love running on the trails in Carolina North, a trail system in Chapel Hill. I ran on these trails 7 years before I moved to NC and they are one of the reasons I moved here!
Running gear you can't live without?
I was going to say my Garmin, but everyone says that, and if i forget mine someone else is bound to have one! Arm warmers. I really think that convertible long sleeves are one of the best inventions ever! Especially arm warmers with thumb holes! Way to go Oiselle!
When you're not running where would we find you?
Spending time with my son or my friends or, far too rarely, my hardworking husband, coaching Girls On The Run or working on my house.
What is your favorite post-race treat?
A latte and, incongruously, a big salad.
Complete the sentence: If I was stranded in a hotel room with one movie and one book, they would be…
Big Fish and Mountains Beyond Mountains.

text: until very recently, my go to stick for steelhead has always been the sage 896 RP. of course this rod, in this material, is no longer made by sage. funny how when they come up with a winner, they change the product. you will occasionally find them on ebay. i have fished with the rod since the 70s and still use it today. my newest steelhead rods are the short skagit variety. kerry burkheimer built me an 11'6" designed for the 550gr skagit line. what a joy this rod is to cast, he does an amazing job of rod construction. he also built, a first for him, a seperate set of the top two sections to enable me to cast a 450gr skagit for the summer fishes. salmon are another whole ball game. for the silvers up to about 12#, the same stuff you use for steelhead works just fine. once you get up into the larger fish, you really should start thinking about a 10wt. when i was river fishing for 20#+ chinook, i never left home without the 11wt, they are just too much to handle on a smaller rod. of course, rod/line weight also should be considered in terms of whether or not you are consumtive fishing or practicing C&R. if the later, you need to beat the fish fast to give them a chance before that lactic acid takes ahold.

Small, but with some genuinely antique artefacts. Not very well presented, but worth the time spent trying to work out how it all fitted together.
Tools and descriptions of many Trades now almost forgotten can be found in this eclectic Museum. The ancient building where Tolls were collected, next to the old Lock up where a Fire Engine was once housed. Volunteers open The Tolsey from April to October daily (not Mondays) 2 - 5pm.
This museum is clearly a labour of love for the locals in Burford. The town has a colourful history and they have collected quite an array of artifacts, presented clearly and logically. The building is charmingly ancient and the staff is quite knowledgeable.
This teeny museum is really interesting. It's an eclectic mix of historical artefacts which tell lots of stories about local life, from witchcraft to buildings to highway men. Well worth a visit if only for 15 minutes!! Not really suitable for children but don't let that stop you!!

Reserve Bank of India Governor Raghuram Rajan has warned that the world economy could be heading towards a crash much like the Great Depression of the 1930s as advanced countries in a bid to pull out of the global downturn are working at cross purposes.
As was the case in the 1930s, the lack of coordination between central banks across the world is producing spillovers that may be difficult to control and could plunge the world's financial system into another crisis, Dr. Rajan said in an interview to the Central Banking Journal on Wednesday.
Dr. Rajan, a former chief economist of the International Monetary Fund, had famously predicted the 2008 global meltdown.
We are taking a greater chance of having another crash at a time when the world is less capable of bearing the cost
The European Central Bank's "very, very accommodative stance" is getting blunted by the ultra-loose monetary policies being pursued by other central banks, including the Federal Reserve, the Bank of Japan and the Bank of England.
To safeguard against such an eventuality, all central banks must unwind their monetary policies in a coordinated fashion, Dr. Rajan recommended.

Following successful runs at the Ustinov Studio in Bath and the Tricycle Theatre in London, Theatre Royal Bath Productions and the Tricycle Theatre will transfer Florian Zeller's Moliere award-winning play, THE FATHER, starring Kenneth Cranham and Claire Skinner, to London's Wyndham's Theatre for a limited season, Wednesday 30th September – Saturday 21st November. In the two weeks prior to the transfer, the production will play a very limited run at Cambridge Arts Theatre, 15th – 26th September
This was my first visit to the Charing Cross Theatre and what a tiny but perfectly formed theatre it is. There is only one level and it is underground with the station up above. The auditorium was hot so I can only imagine how the cast were feeling under the lights, so it is even more credit to them that they did a superb job entertaining us.
Bend It Like Beckham at the Phoenix Theatre is a vibrant new show based on the 2001 film of the same name and is bought to the stage by the same creative team of director Gurinder Chadha and co-writer Paul Mayeda Berges. In addition, the stage production has music by Howard Goodall and lyrics by Charles Hart.
I'm often weary of seeing a show more than once - I feel like nothing can ever be as good the second time as the excitement and suspense is often gone because you know exactly what will happen next. But I have made an exception to this rule for one very special show: Miss Saigon. I've now seen it three times, and each time it just gets better and better. I haven't lost my love for the show at all, if anything it's grown more, and below are just my top five reasons why I love Miss Saigon so much.
The award-winning West End production of Roald Dahl's Charlie and the Chocolate Factory, directed by Sam Mendes, marked its second anniversary with a gala performance and party for cast, crew and special guests.
Based on an original new story by J.K. Rowling, Jack Thorne and John Tiffany, Harry Potter and the Cursed Child, a new play by Jack Thorne, will receive its world premiere in London's West End in the summer of 2016 at the Palace Theatre.

LeSean McCoy will return to the lineup for the Philadelphia Eagles on Sunday against Washington after missing four games with a concussion. Meahwile, quarterback Michael Vick will be the Eagles' No. 3 quarterback behind starter Nick Foles and Trent Edwards and might not be uniform Sunday, The Philadelpia Inquirer reported Wednesday. Vick has sat out five games because of a concussion. Coach Andy Reid said McCoy will rotate in the backfield with Bryce Brown, but McCoy will start. Reid decided to use McCoy after the four-year veteran told him that he wanted to play before the end of the season. "I'll keep a close eye on McCoy," Reid said. "It won't be a normal workload like you'd see." McCoy has rushed for 750 yards on on 177 carries in 10 games this season. Brown has played in all 14 games and and has 528 yards rushing on 103 carries.

Deftly handling matters on both sides of the ball, the Marcellus football has earned a share of the Class B West division regular-season championship.
The Mustangs went to Hannibal Saturday afternoon with the knowledge that Westhill had already beaten Skaneateles the night before, and that Homer was trying to claim its share of first place at Phoenix - which it did with a 33-19 victory.
So Marcellus had to win to get a shot at a playoff home game - and it did, keeping Hannibal off the board until the fourth quarter and breezing to a 34-14 victory over the Warriors.
And as the tie-breaker worked out, Marcellus finished second in B West, ahead of Homer but behind Westhill. Still, that means the Mustangs will host Holland Patent, the third-place team from C East, in Friday's opening round, with the winner to get Cazenovia or Skaneateles in the semifinals.
A big part of this victory was seeing quarterback Kyle Hastings air it out. Hastings had enormous pressure on him when the season began as the successor to Will Fiacchi, the Mustangs' all-time leading passer. And while Marcellus had started 5-1, Hastings had, at times, settled for a supporting role behind the ferocious Mustang defense and its solid ground game.
At Hannibal, though, Hastings did not let anyone get in his way as he threw for four touchdowns, three of them in the first half as Marcellus raced out to a 21-0 lead. Better yet, he made the Warriors pay for all the defensive attention given to top Mustang receiver Chaz Hayes.
In the first quarter, Hastings moved Marcellus to Hannibal's nine-yard line, then found R.J. Linder in the end zone to put his team ahead 6-0. Later in the period, Hastings, from the Warriors' 31, tossed a short pass to Allie Ragovin, then watched Ragovin weave his way in for the TD. Nick Nye's extra point made it 13-0.

"Where do I start! I got a Genesis and it is
super fast and runs really well! Along side of the great computer was
the outstanding customer service! My sales representative was Jake
Netta. He was always their when I needed help and helped me when their
were problems with my configuration to get it fixed as soon and easily
as possible! The customer service is some of the best I have ever used!
After joining the Origin family, I know I will never leave it!"

"Great customer service, and top of the line product. Would recommend to anyone wanting to step up there game."
What others have said. The customer service
was great; I was kept informed when my order was delayed due to a high
volume of orders and generally felt up-to-date about my build. The
computer arrived a day earlier than the expected arrival date and it is
amazing. I could not ask for a better experience.
Nothing but a perfect experience! PC is
balls fast. Awesome support 24/7 (people speak English and actually know
how to help you). Just buy your new PC with Origin and I promise you
will be happy!!!
Great company to work with, keep you
informed throughout the process and handle those last minute changes
with a "no problem". Refreshing experience and the product is
I rarely ever leave positive feedback (but
am quite prone to leave negative feedback when I'm disappointed). And
I've been purchasing high-end gaming PCs for 20 years. I am demanding as
any customer out there when it comes to purchasing high-performance
systems. I want to be able to customize a system as much as possible,
not get gouged (I'm happy to pay for top end products but don't want to
buy stuff at 150%+ of retail), and I want excellent customer service.
These are premium products and we high-performance PC purchasers should
expect premium customer service. And for the last 6-8 years I have been
very frustrated with PC companies. I have tried many of the so-called
"high end" shops and been consistently disappointed. Some might have
great components but absurd prices and horrific customer service. Others
have great prices but the computers are unreliable and the customer
service is non-existent.
So it's remarkable for me to be leaving positive feedback in general.
But after purchasing just one computer from OriginPC I can confidently
say I've found the company I'll be purchasing computers from for a long
time and I'm very happy to leave them positive feedback. First, the
provide a huge amount of customization options rather than some of the
other companies which only provide you with a few boilerplate systems
and very little flexibility to customize. Second, OriginPC's prices are
very reasonable. When you are building an extremely high-end system you
aren't going to be spending $1k or anything like that but you don't feel
like you are being taken to the cleaners by these guys. Third, the
communication once I placed my order was outstanding. And the computer
was delivered on time and was everything I expected it to be. Fourth,
they follow-up was excellent. That there was any follow-up at all is
great because many companies don't follow-up at all. But OriginPC has
been very attentive and interested in ensuring I am pleased with my
Purchased the Genesis tower, have to say I
love it! The design and the amount of space it provides is perfect for
air flow. The reps I have worked with are not only helpful but friendly
too, this is customer service done the right way. I will definitely purchase from Origin PC in the very near future!
I bought an Origin PC recently have been
very happy with everything - the delivery, the communication with the
sales and customer service departments, with the PC itself. Moreover,
due to the reason outside company control I had a problem and contacted
the tech support. The issue turned out to be caused by me connecting a
good but apparently too old for the latest Nvidia GeForce video card
monitor which caused Window failing to start. The response was great:
the person on the other side of the line did not waste time asking
too many general questions, but simply asked me to start up Windows in
safe mode, logged into my computer using the pre-installed TeamViewer
(using a randomly generated pwd I supplied over the phone), identified
the issue by uninstalling the Nvidia drivers, recommended connecting
a newer monitor (which I did), reinstalled the drivers and got my
machine up and running, all in 10-15 minutes - very professional, no
nonsense, tech support.
I will preface this
by saying I have been in the PC industry for 20 years; I am seasoned, I know
what I am doing. I have built machines of every type and size, for every
purpose both home recreation, business professional, and gaming performance.
First of all, the packaging. The packaging alone made the wait worth it - It
felt like an indestructible brick. I will freely and openly admit that I paid
Origin a lot more than I paid [ibuypower] for a machine of comparable
specifications, but the adage in business is that you get what you pay for -
and I certainly did. The whole "wooden crate" thing, I do not know
how much of that overhead went into that cost, but I am extremely glad it was a
forced option and not an electable one. It did make hauling the machine home
from the delivery point a great deal more difficult, but that was still worth
it to know that whatever arrived was firmly, securely, and powerfully packaged.
So far, I have had no problems. It has worked like a dream. Visual Studio runs
like smooth butter even with thousands of projects loaded on this machine (as
it should, per the calculations I made in picking the parts I did) and the video
cards are exactly what we wanted (they were specific chipsets that I wanted for
an extremely specific set of emulative operations.) What was of particular
interest to me was not the performance, though, but the build quality. I'll
start with the visible. Just the metal plating on the SLI cable was an amazing
touch that, again, makes the higher cost worth it. To a veteran computer
builder like myself, I strongly appreciate it when people do not cut corners. I
experienced a lot of corner cutting with [ibuypower], stock cables, everything
loose and dangling, but from the instant I was able to inspect the Origin
machine, and saw the customized, metallic SLI ribbon I knew I was dealing with
a computer built by someone - or a group of someones, after my own heart. This
trend followed true as I explored the other cables as well. The case - whoever
built this series of case needs to be congratulated.
If there is any way to actually communicate with the people who conceived,
designed, and produced this series of case, I really want my appreciation to
get to them. The brilliance in its design is a cacophony of brilliant genius
that was clearly built with the assistance of an HVAC engineer - I should know,
I am surrounded by them all day, and that is what our company does. I was
amazed at the brilliance in the way the airflow system is engineered, and the
modular layout of the case was simply stunning. Moving along, though still on
the topic of the case build and construction - I have assembled, selected parts
for, and completely engineered from the ground up over 600 computers in my
career and I must attest that among them all - between every case I have
purchased, perused, and even some that I custom cut or modified myself, this is
by far and large the most impressive work I have ever seen for a good case. The
"evil eye of Sauron" on the front of the case is a nice touch, and I
am still exploring for the button that allows its nether-filled lidless gaze to
strike laser beams at small flying pests like gnats and moths, but have not yet
been able to locate this feature. The included documentation did not guide me
to such either, but judging from the level of luminescence radiating from it, I
am completely certain that I hear the dark speech of Mordor upon turning the system
on. The way the cables are pulled correctly taught needs to be commented on. I
detest cables. The cabling in cases is among the primary reasons I was forced
to stop building machine, managing and wrangling them was irritating and when I
lost effective use of one of my arms, it became a hassle to build people
efficient and well thought out cases. While I am sure that a look behind the
hidden side panel will reveal a lot of wires I'm uncomfortable seeing, the
machine does not feel as if it is "bursting" at the seams, so to
speak. This is important to me, as with the [ibuypower] machines I bought, the
motherboard-side plating was "bulging", as if it was struggling to
contain the overstuffed cables. While the interior of their machines "looked"
clean - any and all need to perform the slightest maintenance made it quickly
apparent that they were doing everything possible to force as much into that
tiny space as they could.
But it was more than that, not only were the cables clean, they were pulled
CORRECTLY taught. They were not pulled so tight that there was no wriggle room
- there was enough slack in order to move and unplug, rearrange, and do
whatever was necessary – but they were appropriately pulled to ensure
absolutely minimum clutter. This is EXTREMELY important to me. The fact that
the expansion bays were already plugged in and ready to accept new drives was
extremely appreciated. I myself had a hybrid 1 TB HDD that had an 8 GB NRAM
cache that I really wanted to use for some of my programs. I was dreading the
amount of work it would take to add this to the system because I knew it would
involve a lot of plumbing and reworking (when you only have one semi-healthy
arm, any amount is "a lot") - but no, it took none of this. I
literally just unlatched the removable bay, put my internal Hybrid-HDD in, and
it worked. I was fascinated. The machine I ordered had a "custom"
motherboard - that is to say, I asked for a motherboard that was not offered on
their site. They accommodated that request brilliantly, and if the words
"custom" had not been written next to it on the invoice, no one would
be the wiser. They even optimized it specific to the motherboard, instead of a
stock optimizing process. Whoever put that board in there read its instructions
carefully and knew what they were doing. I was even greeted with an excellent
print out of the results of a myriad of tests, benchmarks, and other analysis
run on the machine. This was important to me, because it showed that an actual
person went through the process of installing Windows, installing the drivers,
and then performing intense operations for a period of time long enough to
catch most of the possible early breaking points. The only "flaw", if
it can be called one, is that the 20-pin adapters for the front panel USB 3.0
components were not plugged into the motherboard by default. However after
analysis and physical assessment, I asserted that, due to the sturdy inner-foam
packaging supplied, plugging them in would have been unsafe and risked bending
them. I must surmise then that the decision to leave them unplugged was a
conscious one - and it was a wise one at that. If I had any critique to give,
it would be for the company to note this on the large "poster" that
has the "setup" instructions, as the typical home user will not be
aware to plug them in. I also found that the "Fan Control" dial on
the case is unmarked, as I do not know which direction is "faster" or
"slower". This is a detail easily rectified by an email though, but
it should be printed on the poster-insert. In short, this computer is a marvel
of workmanship by a technical engineer after my own heart, and I am extremely
pleased with my purchase. The build time, and ship time, was extremely long
(almost a month and a half), but it was worth every cent. It was put through
the tests so that when I got it, it did not fail me. The elegance of this
machine is a symphony of technical expertise. As a seasoned, veteran
programmer, system builder, technician, and lover of all things
"computer", this box goes to 11. It cost more than anywhere else I
shopped from, but I absolutely got what I paid for, and more.

intelligence, a city ruled over by Sihon, king of the Amorites (Josh. 3:10; 13:17). It was taken by Moses (Num. 21:23-26), and became afterwards a Levitical city (Josh. 21:39) in the tribe of Reuben (Num. 32:37). After the Exile it was taken possession of by the Moabites (Isa. 15:4; Jer. 48:2, 34, 45). The ruins of this town are still seen about 20 miles east of Jordan from the north end of the Dead Sea. There are reservoirs in this district, which are probably the "fishpools" referred to in Cant. 7:4.

This invention relates to a small bell-shaped latex rubber protector that is designed to be placed over the top of, e.g., an endoscope prior to its passage into a body cavity through a tract thereof. Once it is passed in a folded back position, a sharp, pointed or cutting foreign object can be retrieved from the cavity using a forceps or other accessory. The protector hood is then flipped into the open position by pulling the instrument back through, e.g., the lower esophageal narrowing. The bell-shaped latex protects, for example, the esophagus and posterior pharynx from the foreign body during its removal.
1. A method of removing a foreign object from an internal track of a body, such as a human body, without damaging the wall defining the track, the method comprising the steps of:
inserting a probe into the track in a first direction with an inverted bell-shaped, flexible shield fixed thereto, the bell-shaped shield having an opening facing opposite the first direction and having a peripheral edge engaging the wall of the track;
grasping the object with a tool extending from the probe;
inverting the bell-shaped shield to cover the now grasped object by moving the probe in a second longitudinal direction opposite the first direction with the peripheral edge of the shield in engagement with the wall of the track, and
removing the object from the track while preventing engagement of the object therewith by continuing longitudinal motion of the probe in the second direction.
2. The method of claim 1 further including the step of constricting the edge of the shield to completely enclose the foreign object within the shield.
3. A method of removing a foreign object from an internal track of a body, such as a human body, by using an endoscope, catheter, grasping tool and flexible shield, the method comprising the steps of:
folding the flexible shield, which is bell-shaped with a free edge when expanded, into the catheter and over the grasping tool with the free edge thereof facing in a first direction;
inserting the catheter with the flexible shield folded therein in to an accessory channel within the endoscope;
inserting the endoscope through the body track and into proximity with the foreign object;
removing the catheter to expand the flexible shield;
grasping the foreign body with the grasping tool;
enveloping the foreign body within the bell-shaped shield; and
withdrawing the endoscope from the track along with the shield enveloping the foreign body to remove the foreign body from the track while preventing the foreign body from engaging the track during withdrawal.
4. The method of claim 3 further including the step of constricting the free edge of the shield after enveloping the object to completely enclose the object within the shield.
5. The method of claim 14 wherein the step of constricting the free edge of the shield comprises pulling a draw string disposed around the free edge to substantially close the free edge.
This invention relates to a device for use in removal of foreign objects from a tract of the human body such as the gastrointestinal tract.
It is often the case that foreign objects will enter the human body through regions such as the gastrointestinal tract, for example, by swallowing. Typically, when it is desired to remove a foreign object through the tract of the human body, often damage is caused by removal of the object. Up to now no device has been designed for use, for example, with an endoscope or other like device for removing such objects.
One prior art device which at first glance appears similar in structure, but fails to provide the necessary function is disclosed in U.S. Pat. No. 3,719,190. This patent discloses a heart stimulation eletrode with a conical positioning parachute. The structure of the parachute responds to the blood flowing in a vein to draw the electrode into the heart. When the electrode is withdrawn from the heart the parachute inverts allowing for withdrawal of the electrode without damage to the vein tissue. However, this patent fails to disclose a device for permitting withdrawal of a foreign body from the human cavity and instead, the functioning of the parachute is merely for the purpose of preventing damage caused by the parachute itself. There is no means provided for covering the electrode upon withdrawal through the vein.
Also related is the device disclosed in U.S. Pat. No. 724,913 which relates to a syringe nozzle suitable for irrigating, for example, the rectum. The syringe nozzle includes a bell-shaped member secured to the tip of the syringe with the bell-shaped member sealing against the which the syringe is being employed. This device merely provides a sealing function and the problems of removing a foreign object, with a device which inverts to provide a protective function, from the human cavity through a passage thereof is not addressed.
It is thus an object of the present invention to provide a device for facilitating removal of foreign objects from cavities and through tracts in the human body while preventing damage to the passage tract or cavity of the human body caused by the foreign object upon removal.
It is another object of the present invention to provide such a device for use in combination with an endoscope and instruments for facilitating grasping and removal of the foreign objects from the human cavity. Upon further study of the specification and appended claims, further objects and advantages of this invention will become apparent to those skilled in the art.
In accordance with the invention a device is provided for protecting an internal tract of a human body during removal of a foreign object therethrough. The device comprises protecting means which is movable between a first-position to permit passage thereof into and through the tract of the human body to the region wherein a foreign object is located, and a second position for covering the foreign object when being removed for preventing contact between the foreign object and the walls of the tract of the human body. In addition, attachment means is provided for attaching the protecting means to an instrument to be passed through the human tract to retrieve the foreign object.
In a more specific aspect, the invention is directed to a protecting means sized for passage through a relatively large human body tract such as the gastrointestinal tract. The attachment means is adapted for attaching the protecting means to an endoscope and/or forceps or other like retrieving devices used to retrieve the foreign objects from the human cavity. In a preferred embodiment, the device is a latex hood which is sufficiently flexible to be passed in a folded back position through the gastrointestinal tract to the location of a sharp pointed or cutting foreign body. The protector hood, once the foreign object is grasped by forceps or other accessory is then automatically flipped into the open position by pulling the instrument back through the lower esophageal narrowing. The bell-shaped latex protects the esophagus and posterior pharynx from the foreign body during its removal.
When used with an endoscope, the device provides advantages by flipping back during insertion to permit full visualization. The narrowing at the junction of the esophagus and stomach are then used to cause automatic straightening out of the bell-shaped hood. In addition, the narrow end of the hood is such that it easily attaches to the endoscope by stretching over the end and then securing it in place. A rubber band can also be used to additionally secure it in place.
Various other objects, features and attendant advantages of the present invention will be more fully appreciated as the same becomes better understood when considered in connection with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
FIG. 1 is schematic diagram showing the device of the invention as mounted, for example, retracted or folded back position on a device such as an endoscope after having grasped an object in the human body cavity.
FIG. 2 is a schematic diagram of the device of the invention in retracted or folded back position attached to an endoscope and ready for insertion through a tract of the human body;
FIG. 3 is a view showing the device of the invention after having been folded back into the open position for protecting the walls of the human body tract from damage by the grasped object;
FIGS. 4a and 4b respectively show a view from the open end of the device of the invention and a cross-sectional view of the device of the invention showing the structural details thereof; and
FIGS. 5 and 6 illustrate another embodiment of the invention showing actuation with a drawstring.
As shown in FIG. 1, the device of the invention is shown in a retracted position after having been inserted through the tract of a human body with a foreign object attached to the instrument, for example, a probe such as an endoscope 1, for being retrieved from the human body cavity. As shown in FIG. 1, the device of the invention 7 which is a foreign object protective hood 7 would generally be attached at a tubular flexible extension 15 to the endoscope 1. It includes a generally bell-shaped section 13 which opens into a wide mouth area 17 having a peripheral edge which engages the wall of the track so that when being retracted it folds back into a protective position by bending at a generally more flexible region 9 of the bell-shaped portion 13 with the wide expanding portion of the bell-shaped portion 13 being a thicker region 11. In this embodiment, the endoscope is shown with a magnetic attaching means 5 which is used to secure a pin 3, for example, which has been swallowed by a child.
The figure of FIG. 2 shows the device 7 attached to the endoscope 1 in position for being passed through the tract of the human body just prior to entering the cavity region wherein the object to be retrieved is located in much the same manner as shown in FIG. 1.
As shown in FIG. 3, the device of the invention is shown in a protective position. The inversion of the hood 13 was caused typically by contact with the walls of the tract of the human body upon withdrawal, and preferably a narrowing of the walls which is sufficient to exert enough force upon retraction on the more flexible region 9 of the bell-shaped portion 13 to cause it to invert upon retraction of the device by means of retracting the endoscope 1 with the foreign object to be removed firmly protected and secured within the hood portion 13.
As shown in FIG. 4a, the wide open mouth 17 of the device tapers into a connecting portion 15 for attachment to for example, an endoscope 1. Other uses can be as an atachment to forceps or other like devices for retrieving foreign objects from the body.
FIG. 4b shows a cross section view along the side along lines FF of FIG. 4a showing the various detailed features of the invention. As shown therein, there is a connecting portion 15 which has a wall thickness of sufficient rigidity to be securely attached by frictional engagement to a device such as an endoscope for passage of the protecting hood into the body cavity. However, the wall thickness of connecting portion 15 must also be of sufficient flexibility to permit stretching thereof for passage over the end of the endoscope 1 to be attached thereto. A region 9 having internal radius of curvature R' combined with external radius of curvature R2 generally shown by a region designated as C is provided which is of reduced thickness to permit flexibility in flipping the protecting hood from one position to the other. The selection of the wall thickness and flexibility is well known to one of ordinary skill in the art once the body cavity within which the protective hood is to be used is known.
For example, a body cavity connected by a tract which does not substantially reduce its diameter would require a region C of greater flexibility and thus thinner wall thickness which would move from one position to the other with little or no force depending on the movement of the endoscope in the tract of the body and with minimal wall engagement. On the other hand, a tract which decreases in diameter on withdrawal would not require such a reduced wall thickness as compared to the rest of the device since the frictional engagement with the walls upon retraction could be employed to generate sufficient force to cause the inverting from one position to the other of the protective hood. Region B of the protective hood 7 hood portion 13 generally flares outwardly expanding toward the wide mouth 17 and terminating in a region A which generally tapers into parallel extension with the portion 15 used to connect to the endoscope.
As noted, the device can be made of latex or other flexible material with latex being the preferred material. The material employed must be such that the hood is sterilizable since it is to be used within the body to prevent the risk of infection. To this end, the materials which can be employed are conventional and would be well known to those of ordinary skill in the art.
Included among these materials are such as silicone rubber, shaped by an injection molding techique. More particularly, any material that is bio-compatible, flexible and elastic would be suitable.
In addition to the above discussed embodiment, the hood can be made of a size such as to fit into a catheter small enough to fit through the accessory channel of an endoscope. In this case the hood will be positioned over, e.g., a grasping type forceps or other instrument, to grasp a foreign body. By withdrawing the hood into the catheter, this will cause it to fold onto itself.
In actual use, once the catheter is passed through the endoscope, it is withdrawn, allowing the hood to expand to provide protection against the foreign body. In this case the hood will not flip into a protecting position since it will already be in the protecting position. Instead, it will be sufficiently flexible to be collapsible so as to be in a collapsed position when located in the catheter. When the catheter is withdrawn, it expands to provide the protection desired. This embodiment will look very much like that of FIGS. 3, 4a and 4b, except that it will not flip back as shown in FIGS. 1 and 2.
A still further embodiment is shown in FIGS. 5 and 6 involves the use of a drawstring arrangement. As shown in FIG. 5 the arrangement includes a channel 19 at the open end of the hood 7. A drawstring 21 extends through the channel 19, and backward along the endoscope 1 and is held in proximity thereto by string support means 23. The string support means are shaped as blunt as possible to avoid injury to the body cavity in which it is employed.
As shown in FIG. 5, when the foreign object is safely contained within the hood 7, the string 21 is pulled to close the open end of the hood 7 into a sacklike configuration.
From the foregoing description, one skilled in the art can easily ascertain the essential characteristics of this invention, and without departing from the spirit and scope thereof, can make various changes and modifications of the invention to adapt it to various usages and conditions.

Carnegie Mellon University Undergraduate Admission
Choose Your Program. Change the World.
All applicants for the undergraduate Bachelor of Architecture degree program must submit one of the following two options for review by the architecture admission committee: either the architecture portfolio of creative work or the architecture design project. The architecture admission committee will value the architecture portfolio of creative work or the architecture design project submissions equally, so you should choose the option that best fits your needs.
The architecture portfolio is the best option for applicants who would like to present a body of creative work completed within the past four years. The portfolio submission will include the completion of two forms and the compilation of ten different creative works. If you decide that the portfolio is not the best option for you, the architecture design project submission may be a better fit for applicants with limited portfolio work to demonstrate creative problem-solving ability.
If you choose to submit the architecture portfolio, please keep in mind the following:
Review the architecture portfolio preparation tips for more information about the content of the architecture Portfolio.
All architecture portfolios are submitted electronically on Carnegie Mellon's SlideRoom portal. You must first register/create an account in order to begin uploading the content of your portfolio. Architecture portfolios must be submitted according to the deadline for your portfolio to be reviewed by the architecture admission committee.
Visit the SlideRoom Architecture Portfolio Portal to electronically submit your portfolio to the School of Architecture.
The School of Architecture strongly recommends that applicants visit campus for an on-campus portfolio review. As part of an on-campus review, you'll come to campus to interview with architecture faculty about your previously submitted portfolio or design project, and receive an introduction to the school. You'll be able to ask questions and engage with faculty, students and staff within the School of Architecture. (The School of Architecture faculty doesn't critique or evaluate portfolios outside of the scheduled on-campus reviews noted below.)
The School of Architecture requires an online submission of your architecture portfolio or design project even if you plan to come to an on-campus review. Your previously submitted work will be available during your review. Visit SlideRoom to electronically submit your work.
2014-15 On-Campus Portfolio Review Dates:
November 9 (Early Decision Applicants Only)
January 18
January 25
If participating in an on-campus portfolio review:
When preparing your architecture portfolio, keep in mind that we're interested in understanding your creativity in all its facets – invention, creation, process, and composition. As a result, we require you to submit a variety of creative works that demonstrate your inquisitive nature, innovative ideas, spatial reasoning, visual thinking and your desire to make and build things. Your portfolio is intended to expose your ability to analyze, problem-solve, think critically and synthesize.
We're also interested in determining your commitment and motivation to study architecture. We advise that you consider the process of assembling and submitting your creative/inventive work:
All architecture portfolios are submitted electronically, so please prepare your work for digital submission by photographing and/or scanning high quality images of your work. The School of Architecture allows the submission of ten different works; you'll only be able to upload one image of each work, so please select the image that best represents your work.
Please keep in mind that the architecture admission committee who will be reviewing your portfolio is more interested in understanding your creative intent and design process than your mastery of specific skills or techniques. For this reason, you should avoid submitting drafting work (CAD) as part of your portfolio of creative work.
How do I submit my architecture portfolio for review?
Submit your architecture portfolio electronically on Carnegie Mellon's SlideRoom portal. You must first register/create an account in order to upload your portfolio.
What if I've already registered/submitted an online portfolio through another institution's SlideRoom portal?
Many institutions use SlideRoom as their applicant portfolio management system, so if you've already created an account, you don't need to create another one to submit to Carnegie Mellon. You may use the email and password that you've already created on SlideRoom to submit a portfolio to Carnegie Mellon. Please note that the SlideRoom system only allows applicants one email account.
Who do I contact if I'm having a technical issue?
Once you've registered, you'll see a Help tab on the online portal. From this section of the website you'll be able to submit your technical questions and a representative from SlideRoom will contact you. Technical issues with submitting your online portfolio should not be sent to Carnegie Mellon.
Do I need to submit multiple portfolios if I'm applying to more than one area at Carnegie Mellon?
Yes. Architecture, Art and Design at Carnegie Mellon are individual schools, with separate majors, faculty and admission processes, and therefore, different portfolio requirements. You can indicate which school you wish to submit your portfolio to upon registering/creating your SlideRoom account. Portfolios submitted to only one area will not be viewed for other programs.
How much does submitting an online portfolio cost?
Each portfolio submission requires a $15.00 fee that is paid online. For example, if you're submitting your portfolio to the School of Architecture and the School of Design, you'll be charged $15.00 for each school or a total of $30.00.
The architecture submission section of SlideRoom will only allow me to submit 10 images. Can I submit more?
No. The architecture portfolio consists of 10 different works, no more, no less.
I have a piece of work that consist of more than one picture, like a 20 page illustrated book. Is it possible to submit multiple images of one work?
We realize that many applicants have works that cannot be shown in their entirety. It's up to each applicant to edit and present their work in the way that best shows what they're doing within the limited frame of the application portfolio. What you choose to include and exclude can show reviewers something about what you consider to be important about your own work. Please select one image that best represents each work.
Am I able to provide a description of each work?
Yes. SlideRoom allows you to provide a description of each work including a title.
As there are size limitations to what I can submit, am I permitted to send a couple DVDs of higher quality by mail in addition to the versions uploaded onto SlideRoom?
No. The portfolio reviewers are not accepting any mail-in portfolios or supplements and will only review work submitted electronically through SlideRoom.
I plan to come to campus to show my portfolio, do I still need to submit my portfolio electronically?
Yes. The School of Architecture will only accept portfolios submitted through SlideRoom and your electronically submitted portfolio will be made available during your on campus review.

A method is described that enables a system to estimate the individual times of arrival of multi-path signals components in a received signal while blind to the particular angular response characteristics of an antenna array. Additionally, a system is described that estimates the impulse response of the modulation channel.

Digital signals are often filtered using a pulse shaping filter prior to transmission. This is typically done to contain the signal bandwidth and minimize intersymbol interference between signal components corresponding to different digital symbols. This is shown in
An artifact of this signal generation provides an unintended feature that has been the focus of recent investigation. If the digital signal is passed through a multi-path channel, the channel output is an aggregate of delayed, possibly faded and phase shifted replicas of the original digital signal. In practice, this occurs if a multiplicity of reflections of the transmitted signal are contained in the received signal. The delays can either be absolute, if the time of arrival of the direct path signal is known, or could be relative delays between the multi-path components. If these multi-path signals are received at the antenna array, the received signal can be mathematically formulated as a space-time signal.
When the characteristics of the pulse shaping filter and the antenna array are known, a theory of signal processing can be applied to estimate the multi-path delays of the signal components and their particular directions of arrival. This signal processing analysis is referred to as space-time processing. Space-time processing is a group of techniques that may be applied to resolve the received space-time signals into a sum of faded space-time signals. Each of these space time signals corresponds to the particular angle of arrival and time delay of one of the original multi-path signal components.
It is advantageous to develop a mathematical description of the prior art technique to convey the manner in which multi-path delays and angle of arrival ("AOA") are currently calculated to fully appreciate the distinctness of the to be disclosed subject matter. The prior art method is illustrated in
A column vector rk denotes the received signal at antenna k of an antenna array with m antennas, where k=1, 2, . . . m. An impulse response hk of the multi-path channel is derived from rk, represented in block 201. The derivation of the column vector hk can be achieved by various methods and implemented with signal processors through software and/or hardware.
If the source data associated with this received block is known, a simple means of extracting hk is via the delay matrix corresponding to this source data. The delay matrix Z is formed by stacking symbol shifted copies of the source data in rows to a depth that defines the extent of the desired impulse response and truncating its longer dimension to match the length of rk. An estimate of hk is given by: hk=(ZZH)−1Zrk.
Alternate means for estimating the impulse response may provide better or worse estimates, depending on the particular modulation format of the data, the block length, the fading characteristics of the multi-path channel and possibly other parameters. Some of these other methods are blind to the actual data transmitted, using properties of either the signal modulation and/or of the channel instead.
Having estimated the impulse response of the multi-path channel from the source to antenna k of the array, a vectorized space-time impulse response over the entire array is formed, in block 202, by stacking the individual impulse response estimate hk into a long column vector {right arrow over (I)}, given by:
Theoretically, {right arrow over (I)} can be expressed as
Any particular Ii is of the form Ii=βiηα(θi)
The vectors α and g can be expressed as:
In the equation for g(τi), l denotes the sampling depth of the pulse shaping function and Ts is the sampling time.
Given this formation of the space-time impulse response, when the number of multi-path components is smaller than the dimension of the symbol sampled impulse response vector I, it is possible to estimate the multi-path delays τi and the multi-path arrival angles θi.
The prior art approach to estimating the delays and arrival angles relies on an explicit knowledge of the aggregate of all vectors:
The observation that Ii is contained in K leads to a primary objective of space-time processing: searching the manifold K for weighted linear combinations of vectors Ii such that a best fit to the observed space-time impulse response {right arrow over (I)} is generated as shown in block 204. A variety of techniques may be applied for this purpose, such as Multiple Signal Classification (MUSIC), The Method of Alternating Projections (APM), etc, which can be implemented through software and/or hardware. Other mathematical descriptions for jointly estimating the angle of arrival ("AOA") and time delays can be found in Ziskind, I., Wax, M., "Maximum likelihood localization of multiple sources by alternating projection", IEEE Trans. Acoust., Speech, Signal Process. vol. 36, no. 2 (October 1988), 1553-1560; Van Der Veen, M, Papadias, C. B., Paulraj, A.

An object of the disclosed subject matter is to obviate the deficiencies of the prior art by removing the dependency of the time delay estimates from the spatial and gain characteristics of an antenna array thus allowing multi-path delay estimates to be obtained for any generic antenna array. This object is achieved by recasting the array manifold in a spatially blind manner so as to be independent of the array characteristics.
It is another object of the disclosed subject matter to present an improved method for estimating the multi-path delays in a signal received at any k array element. The method includes estimating an impulse response at each k antenna, generating a space-time impulse response, and forming a covariance matrix and resolving the covariance matrix with a known antenna array manifold. Additionally, a novel improvement to known methods includes the step of resolving the covariance matrix with a fictitious antenna array manifold.
It is still another object of the disclosed subject matter to present a novel method for estimating the multi-path delays in a signal using a spatially blind antenna array. The method includes generating an impulse response hk for each antenna k in the antenna array and determining a vectorized space-time impulse response I over the antenna array. The method further includes creating a covariance matrix C, a fictitious manifold Af, where Af is spatially blind and independent of the array characteristics, and then resolving the covariance matrix C with the fictitious manifold Af to estimate the multi-path delays τi in a manner independent of the array characteristics.
It is yet another object of the disclosed subject matter to present a method of estimating the multi-path delays of a sequence of j blocks of a signal received at an antenna array comprising k antenna elements independently of the spatial array characteristics of the antenna array. The method includes deriving a channel impulse response estimates hj,k for each block j at each antenna k and determining a vectorized aggregate space-time impulse response I for each block j. The method includes the steps of forming an estimated covariance matrix for the sequence of j blocks, forming an array manifold Af void of spatial information; and then resolving the covariance matrix with the fictitious array manifold Af to determine the multi-path delays τi.
It is also an object of the disclosed subject matter to present a novel system for estimating the multi-path delays in a signal using a spatially blind antenna array. The system includes an antenna array, a means for generating an impulse response hk, a means determining a vectorized space-time impulse response I and a means for creating a covariance matrix C. The system also includes a means for creating a fictitious manifold Af, wherein Af is spatially blind and independent of the array characteristics; and a means for resolving the covariance matrix C with the fictitious manifold Af to estimate the multi-path delays τi independent of the array characteristics.
These objects and other advantages of the disclosed subject matter will be readily apparent to one skilled in the art to which the disclosure pertains from a perusal or the claims, the appended drawings, and the following detailed description of the preferred embodiments.
The present disclosure presents a system and method for a technique for determining the individual times of arrival of multipath signal components in a received signal. The delays in the multipath components are determined by creating a fictitious array manifold Af in which the directional knowledge of the array is absent. As discussed earlier, the vector a is produced with the knowledge of all the vectors for all angles θi, is represented as:
To remove the dependence on θi, each dimension of the array takes all possible complex numbered values. The independent aggregate vector is then given by:
As discussed above, the signal processing flow for the established prior art technique is shown in
The signal processing flow for the above-discussed subject matter, on the other hand, employs a fictitious array manifold as shown in
To facilitate understanding of the novel techniques described herein, an example follows for the case of a signal received at a two antenna array in which the established prior art space-time techniques derive delay estimates on a multi-path signal, followed by estimates developed by use of a spatially blind antenna array according to an embodiment of the present disclosure.
A sequence of blocks of signal received concurrent in time at the two antennas are denoted by rjk where k=1, 2 and j=1, 2, . . . J, the index j counts the blocks and of course the index k references the antennas, two in this case. It is, of course, to be understood by those of skill in the art that the present discussion is exemplary only and that the techniques described herein are in no way limited to antenna arrays composed of only two antenna elements. The disclosed techniques are applicable to antenna arrays of an arbitrary number of antenna elements. If the source data associated with each block is known, possibly from demodulating the received signal at either or both of the antennas, or by demodulation at some other receiver, the delay matrix can be developed as illustrated in the previous section and this can be used to derive channel impulse response estimates for each block at each antenna. Thus hj,k=(ZjZj H)−1Zjrj,k, where hjk is the impulse response estimate for block j and antenna k, and Zj is the delay matrix for block j.
The vectorized aggregate space-time impulse response for block j is given by
Most known methods for extracting an arrival angle do so by operations on C. Other methods that operate on the sequence {Ij} differently can also be used.
All established techniques for estimating the path delays and arrival angles in the space-time context require knowledge of the array manifold A which is the aggregate of all possible vectors:
Most established prior art techniques estimate the delays and arrival angles of the multi-path signals by decomposition of the covariance matrix into a sum of estimated impulse responses. This is done using the space-time manifold:
The estimated covariance matrix is resolved into estimates of the impulse responses associated with each multi-path component. Each estimated impulse response is drawn from K and therefore points directly to a particular delay and arrival angle.
In accordance with an embodiment of the disclosed subject matter, an example using a spatially blind estimation techniques for the time delay estimates is illustrated below for the same scenarios as described above.
To obtain the delay estimate without knowledge of the antenna array or an explicit knowledge of the antenna gains, a fictitious array manifold is used, A′f, given by the aggregate of all vectors,
The process estimates the delays without knowledge of the actual array manifold A by using instead the fictitious manifold A′f, so that A′f replaces A in the space-time manifold K=A
The estimated covariance matrix is resolved in order to estimate the impulse responses associated with each multi-path component. Each estimated impulse response is drawn from Kf and maps directly to a particular τ and complex vector [α1,α2]′. The signal processing flow for this embodiment is shown in
The earliest arrival time is of particular interest in many applications such as cellular geo-location. This technique, termed BLind Space Time ("BLST") permits the estimation of relative delays in multi-path signal components using arbitrary configurations of antennas in an array. This, for example, allows one to apply the method to antennas that are separated by arbitrary distances and with arbitrary gain characteristics. Existing antenna configurations in the cellular wireless network can be used without the need for calibration of the array. Calibration is a tedious task that needs to be updated often as a known array is required for signal processing according to the prior art. Thus the use of Blind-Space Time for estimating multi-path delays allows for the application to any arbitrary antenna array without requiring calibration.
While preferred embodiments of the present inventive system and method have been described, it is to be understood that the embodiments described are illustrative only and that the scope of the embodiments of the present inventive system and method is to be defined solely by the appended claims when accorded a full range of equivalence, many variations and modifications naturally occurring to those of skill in the art from a perusal hereof.
