PORTRAITUBAN REFUGEE Andrew WIzson
A recent article on the personality of the Libyan pointed out that "any attempt to characterize all memberso-
composite personality of certain Cuban refugees Is fraught with even greater likelihood of error with respect to Individuals because the sample under study is much less homogeneous than the Libyan was. It ranges from Illiterate peasants to highly educated members of professional groups; the level of intelligence, which is comparable over-all with that found to the United States, runs from nearly deficient to superior. In addition, while the Libyan data were gathered through It; administrationsychological test designed for suchthe data analyzed ln the present study are theof assessments conductedariety of reasons, olten under much less than Idealwo characteristics were common to all members of the group: all had fled Cuba because of their opposition to the Castro regime, and at the time of their assessment all were either candidates for anti-Castro clandestine activity or actively engaged ln such

r. but the general portrait presented below mayrame of reference from which to consider the individualassessment. Successful handling will of coursecareful study of the Individual agent, for how anyreacts to the psychological and environmental forces acting upon him at any given time depends upon his own life history and his current needs and motives.
The Idale: Social Relationships
During his early years the typical Cuban male is Inclined to be highly responsive to the world around him and to the people^ln^lt. Since he^lAjerr sensitive to others' needs and can respond appropriately lo'these needs, people tend to seek him outompanion and cater to him.esult he Is apt to be somewhat spoiled, relatively immature, and over-dependent upon those who take care of him. Be discovers It Is easy to And people who will do things for him and make allowances for his deficiencies. As he grows older, however, and Is expected to show more Independence and self-reliance, he may see, perhaps for the first time in his life, that histo play on others' feelings is not enough; rather than being able to gain support from others for what he Is, he only meets with criticism for what be cannot do. His solution for this problem Is to develop means to keep peopleistance, not only so they will be less demanding of him but also tohis own tendency to become Involved with them. At the same time he learns, unconsciously, to become more rational and leas emotional In his response to his environment
On the surface, then, this representative Cuban exhibits considerable defenslveness andind of detachment in dealing with others. He Is actively social, relating easily to othersuperficial basts, but the chip on bis shoulder Is readily apparent when he Is threatened with becominginvolved. Heery favorable first impression but deliberately holds peopleistance so that they will make no more demands on him than he think! he can If they do demand more, he may withdraw from the situation, thus gaining the reputation of being fickle andIf withdrawal is not possible, he can be actively cruel and hostile toward those with whom he is most intimate, turning on them unexpectedly and violentlyeans of forcing them to retreat. He has at all times tbe potential
for over-responding: he can be loo demonstrative toward and involved with people and activities which by his criteria be finds proper and worthy, and at the same time he can be equally demonstrative against and hostile toward objects which he considers bad or Improper. This sort of loss ofIs often followed by guilt reactions characterized byand apathy, and In this phase there may be rnany expressions of Inferiority or unworthiness
Thereonsiderable number of Cuban males whonatural social skills and interpersonal sensitivityabove. Most members of this second groupieae- *
ceptance. That Is, they try to achieve recognition for what tbey can do, not for what they are. Since they are very much aware of the need to maintain some sort of social adjustment, even though it be superficial, they tend to be much concerned with the impression they make on others. They are quite moody and unpredictable in their prolonged associations with others, reacting strongly to real or Imagined criticism of their behavior. An alternative solution for this group Isimited but reasonably comfortable social role which Is rigidly maintained even if It becomes Inappropriate. Tbe displaced person who does not change his way of behaving ln spite of loss of wealth, rank, position, or status probablyin this subgroup. An example would be the formerofficer who acts toward his civilian colleagues as If he were still In command of troops.
Attitudes tencara Work
At the same time he Is making this adjustment In hiswith other people, the typical Cuban tries to be less emotional and more rational In his view of the workL He tends to Immerse himself In his daily routine and toas if heelf-disciplined individual without need for external direction and control. He admires Intellectual achievement ln others and can himself learn facts andfairly rapidly, but these attributes only make himbetter Informed and intellectually oriented than he is In fact or he himself feels. Since he can retain Information with more ease than he can assimilate or understand it. be tends to be defensive when he meets with any form of testing or criticism. Unless heupervisor whom be respects
and admires, his work productivity tends lo fall off when he Is criticised. On the other hand, he can work quitewithout constant supervision If he knows exactly what he la supposed to do or If he is working alone. It Is stressful for him to be subjected to continual demands to relate to others. His initial reaction to such demands Is furtherand then if the demands persist either violentagainst those making them or flight from the situation.
Theremaller but still numerous group whose outward behavior under normal circumstances is quite similar to that just described but whose reaction to solitude la quite different, TriesWhoTigh alio1 active and'dedicated to' tbeirjjobs.ery tense and agitated when placed in situations which do not allow them to Interact with others. For them stress Is solitude; they require outside distraction and social demands In order to maintain their adjustment.
Emotional Expression
Another mental mechanism the Cuban male uses tohis tendency toward emotional Involvement withIs denial of his Inherent sensitivity. He avoids thefor expressing his feelings by relying on procedures, rules, and regulations of social Intercourse and work activity. His underlying sensitivity Is evident In his ability to temper this Impersonal behavior with judgment; at tbe same time,he does not have his emotions under complete control, so that he is apt to be somewhat Inconsistent andIn his behavior. He can be cruel or even sadistic when one least expects It or. on the other hand, almost overwhelmed by guilt and remorse at having been cold or cruel to others.
By virtue of the very sensitivity he Is trying to control, the Cubanretains the Imprint of the culture from which he springs: he is apt to be devoted to the traditions and mores of his early surroundings. He has so learned tha rules, regulations, customs, and procedures his society follows that helueprint to guide him In almost every situation he may meet.esult, he Is very cautious about adopting new ways to meet new situations; he does not readily accept new Ideas unless he has some assurance that bis peers understand and accept them. In this sense be lacksand adaptability. He may be prone to prejudgments and logic-tight mental compartmentattoo; that is, he may be
able to recognize that he Is behaving LncoruiLstently andfrom one situation to another.
The Female
In general, the composite Cuban female sampled parallels tbe male In hernitially sensitive, she, too, must learn to become more aloof and less involved with the people in her world But her solution for the problem Is considerably less efficient, psychologically, than that of her male partner.
The typical Cuban female tends to be oriented somewhat less to the Intellectual than the male. This doea not mean that sheds"less intelligent butaware of tbe demands made on her by the environment She tries to reduce these demands by losing herself ln the routine activities ot ber life,ertain lack of procedural skill with sheer conscientiousness and determination.more than the male, then, she can perform boring,and repetitive activities for long periods with littlefatigue or loss of efficiency. Since she Is deliberately not Interested In making herself socially acceptable to moreew persons, she can function quite adequately inwhich most people would consider unfriendly, cold, or unrewarding.
The obterTatlona which follow are tentaUve Indeed; they are buedery small sample, probably not at all representative of Cuban women in general.
W ft 'va--'
At the same time, however, since she Is fundamentallyupon someone In her world for support, guidance, and gratification of her needs, she tends to be loyal toew key Individuals. (The bond she has with them Isermanent ooe, for she can switch heralbeit with considerable initial difficulty, from one to another supportinghus on the one hand shemost approaches to social Involvement by anand fairly rigid adherence to conventional socialor. when particularly pressed, by being activelyor hostile, and on the other she Jealously guards the few more Ultimate relationships which she has cautiouslyand views any threat to these with considerable anxiety and susplciocL In the absence of threat, her long-term relationships are more predictable and less fickle than
jse of the male, but they are no more satisfying. In the lung run, than his disappointing superficiality.
Operational Implications
Given these personalities as generic, what tendencies with respect to major strengths and weaknesses and potentialproblems can be anticipated? The male, especially, mayotential for being particularly adept atand describing the feelings and attitudes of othershimself becoming so involved as to lose his objectivity. To the extent that this ability were verified In the Individual
**Wm-or assess the relationships among membersroup. The female Is much less likely to be adept at such evaluative tasks; she has more often pushed the development of Impersonal work skills at the expense of her fundamental sensitivity.
The main psychological disadvantage of the adjustments we have discussed here Is that theyreat deal of energy to maintain. Both male and female are under considerable pressure to become more Involved with others than they wish to be. Keeping uninvolvcd leads to marked strain and tension which are often relieved by the use of alcohol and drugs,not usually to the point of alcoholism or addiction. Obviously, the case officer must check on his agent's tolerance for fatigue and stress and how he counters these strains.
anagement point of view the Cuban may seem disappointing in long-range performance and at the same time overly sensitive to criticism. The male, seeming morethan he himself feels and being verbally fluent and able to learn procedures quickly, may appear to understandwhen he really does not. Thus he may be overrated during training, and In operations the discrepancy between expected and actual results may be increased by his lack of versatility: once be hasay of doing things he does not readily shift to new patterns which may be demanded by the operational situation. On the contrary, he may persist In partially learned but inappropriate modes of behavior. The female, as we have seen, is somewhat less capable procedurally, but her dogged application covers her Inefficiencies.
Each thereforeotential for underlying feelings of Inferiority. Direction and control are necessary, butand testing, especially from someone who Is not respected

and admired, may be extremelyupervisor must be careful to direct his criticism to the methods and procedures being used rather than lo the performance of the individual But any change of procedures must be preceded by long and careful training.
The biggest problem appears to be that of long-term loyalty and control. Essentially, the Cuban Is loyal only to himself.ew exceptions, he cannot tolerate close relationships for long periods of time; only temporary liaison Is possible. In his relationshipase officer he will tend to viewoUeague rather thanubordinate.
In the approach to theainstaking study of her emotional needs must be made In order toay to win her from those to whom she feels loyalty. The male, on tbe other hand, can often be subverted by appeals to hisorientation and devotion to objectivity. One consequence of these mental mechanisms Is that he usually has quiteJustifications, In his own mind at least, for all hisIt may then be possible to provide him with anrationale for engaging in activities Inconsistent with or contradictory to his usual pattern. If this is done the new action will no longer be perceived as beingand can be carried out with little or no anxiety.Original document.

Hosted by Governor Rick Perry and First Lady Anita Perry, this year's conference will recognize Texas-based, women-owned businesses that lower their companies' environmental impact.ξ More than 75 speakers are leading seminars on personal development, work-life balance and other women's issues at the tenth annual Texas Conference for Women next week.ξ CNBC's Suze Orman says the economy is also an issue for women.
"Money is the foundation of everything right now.ξ You're either happy or sad because you have money or you don't have money.ξ So if there has ever been a time for a woman to be powerful about her money, it's right here and right now.ξ Real estate that is down dramatically.ξ You have 401 (k) plans that have become 201 (k) plans.ξ Even though the stock market has recovered somewhat, it hasn't recovered to where it was in 2007.ξ You have unemployment hitting approximataely ten per cent.ξ It doesn't matter what programs happen to be in existance.ξ All that matters is what you can do to save yourself."
Orman says she's noticed something about those who come to her for financial advice.
"So now the change is they're coming to me not with the fear of them losing their job, not with the fear of their portfolios going down, not with the fear of them buying a piece of real estate that may be wrong, but with the reality that they did lose their job, they did lose money in the stock market, they are in credit card debt.ξ The credit card companies are absolutely — especially the ones from the banks — treating them so horrifically.ξ The major banks, like Citi and Chase and Bank of America — all three of those banks should be so ashamed of themselves as to how they are treating the credit card customer.ξ It's not even funny."
The Texas Conference for Women is set for next Thursday at the George R. Brown Convention Center.ξ Ed Mayberry, KUHF Houston Public Radio News.ξ

It is nestled in a landmark 24-story office complex of two buildings and nine interlocking towers that are home to many of the city's top professional services companies.

The center boasts 24-hour, secure underground parking and has easy access to major freeways. Although there is a restaurant on-site, the center is close to the amenities and entertainment of the city's Arena District, The Short North, Brewery District and German Village. The center neighbors the Ohio Statehouse and government jobs are important to the city, but Columbus is pro-business and has a diverse economy.

Looks like another Hurricane on its way to the gulf coast. Any word on where it's predicted to hit?
looks like between galveston and beaumont
which once again puts me in the part
i gassed up today //should be here around the end ofthis week :grrrrrr:
il be evac. if the track stays the same
I really freakin hope it doesn't hit SE Texas! I don't mean to wish it upon anyone else, but I just went through the headache of evacuating last week!! So many hurricanes this year!
i hear that matt! :lol:
well it looks like it is comming straight towards me! im about 40 min away from galveston (which is where it is projected to hit) !!
still up in the air about evacuating .. ..it cost so much to take the rv anywhere these days (pulling it with a 2500 dodge diesel @ 9 mpg) :grrrrrr:
we have a genny and several cans of fuel..
well see :neutral:
yall all please pray for all of us down here ..its been a while since we have had a bad hurricane..
im so glad im in the northeast, but stay safe guys!!! hope it doesnt get you!!
It'll probably miss central TX just like all of the other hurricanes. But it is heading straight towards south TX (brownsville) area right now.
Current predicted path
Computer models (ie. possible paths)
Looks like it's going to slam into South Texas somewhere, who knows where these things will hit. Best of luck to everyone down there, stay safe and get out if there is an evac. :great:
They said Corpus Cristi on the news a few minutes ago. If that is so, we will be getting some rain around here.
Looks like it's starting to flood in Galveston already, storm isn't supposed to hit until another 12 hours from now ... looks like it's going to be a bad one.
Don't hear warnings like this all the time.
As Hurricane Ike bore down on the Houston area on Friday morning, the National Weather Service issued a stern warning to people living in small houses on Galveston Island that they faced "certain death" from flooding if they remained in their homes.
The gas prices over here are going up because of Ike heading toward texas. The only stations that arent going up are the ones that are getting foreign oil.
Dude should have probably not been here I think ... anything for the perfect angle though. Remember, he's blind by the lights from the camera too. ;-)
IKE is going to be bad. I'm in River Ridge Louisiana -4 miles West of NOLA. 30 mph winds started here at 1pm yesterday ,and are still blowing 21 hours later. IKE has brought a LOT MORE RAIN than Gustav ,and much longer lasting winds. The winds were maybe 60 mph with Gustav, but we were just 60 miles from its center. We were never closer than 260 miles from the center of IKE- it is a much bigger, wetter storm with more surge.
Good luck to Houston metro and Lake Charles. They will have some surge(Galveston will have huge surge), but lots of wind and rain flooding. Their power will be out for days/weeks.
Ike looks like it fills up almost the entire Gulf Coast! How can a storm be THAT big?
Saw this quote: Hurricane Ike is following a track similar to the 1900 Galveston hurricane that killed 8000 people, the deadliest storm in US history
We're fortunate to live in a country that was founded on the principles of helping people, learning about the environment and protecting life. That's why we have evacuations ... an attempt to saves lives.
"Surf's up" in Galveston! I lived in La Porte for 25 years and I was told they evacuated it yesterday (right next door to Deer Park). We were at 14' elevation where I lived and the "surge" is expected to be between 15' to 20'. I sure hope all goes well for those staying.
Just saw video of Hurricane Ike knocking down Geraldo! lol! Why rush into a storm? Too bad the camera wasn't directly on him.
Probably the last lighthearted moment before something big and very damaging hits tonight.
im right smak dab in the path of ike
were suppose to get cat 4 or 5 surge
there are alot of nearby cities that are on the water and they are alrady have lottts of flooding ..and the thing has not even made landfall... my family and i have decided to stay ... i am thinking that is a bad idea .. we have never flooded but this may be the big one.
i am very concerned thatmy truck may get water
my city is not evac but most are that are around us (im in deer park tx )
city officals are expecting us to loose power so it may be a few weeks before i regain power/internet
this one is goin to be bad... is anyone else close to me??
they are expecting the whole island of glaveston to be under water ..
Wow, well I wish you the best. If you can get out, it might not be too late. I looked up Deer Park and your elevation is only 24 feet, so you might get wet it looks like. :neutral:
This storm is HUGE, so it's about to hit you pretty hard. We're expected to get 45 MPH winds starting tomorrow and we're hundreds of miles inland.
Here's Deer Park, it's the red dot in the greater Houston area.
Here's the overall Hurricane:
and booooom
I would like to leave but my family does not want to
we have a generator and plenty of supplies
we boarded up the windows ...with fence pickets :lol:
the Boliver Penn. is under water @ this time ...
the storm is expexcted to hit @ 2am and be a weaker cat 3 with storm surge of a cat 5
i may not have a truck by this time tommrow .. and wont have power
i pray for all in the wrath of this storm
God Bless

Primary ExaminerT. H. Tubbesing Attorney, Agent, or Firm-Christensen, O'Connor, Garrison & Havelka [57] ABSTRACT A transceiver-responder identification system which utilizes a swept frequency spectrum signal in the microwave frequency range. The energy generated by the transceiver portion is transmitted in a predetermined number of discrete frequency steps within a frequency octave. This swept spectrum signal is received by the responder portion, which doubles the stepped frequencies comprising the swept spectrum signal, and then routes the signal through a selective filter arrangement comprising a transmission line bounded by a series of directional ring filters, each filter being tuned to one of the frequencies in the swept spectrum signal. If the ring filter corresponding to a specific frequency is physically complete, the signal energy present at that frequency will be coupled into the ring and subsequently dissipated in a load. if the ring filter corresponding to a specific frequency is not physically complete, the signal energy at that frequency continues along the transmission line. This remaining signal energy is then retransmitted to the transceiver portion. By arranging complete and incomplete rings in a unique pattern for each responder in the system, each responder will then transmit a signal unique to the animal or article bearing the responder, which signal is decoded by the transceiver and converted to a corresponding digital word comprising ones and zeros. This digital word provides a common format for article identification purposes. The ones and zeros correspond to the presence or absence of return signal energy at the various frequencies originally generated and transmitted to the responder.

Patented May 27, 1975 2 Sheets-Sheet I kQWQEAIII RESPONDER FOR USE IN A PASSIVE IDENTIFICATION SYSTEM BACKGROUND OF THE INVENTION A reference is made to copending application Ser. No. 405,744, entitled A Passive Identification System, and which is assigned to the same assignee as the present invention, and which is directed toward a pas sive identification system.
This invention relates generally to identification systems, and more particularly, to identification systems wherein given units in the identification system are passive.
At present, due to increasing automation, there is a significant need for inexpensive, reliable, passive identification systems. Passive identification systems are generally used where it is desirable to maintain selective, individual control over a large number of items comprising an inventory system which is constantly in a state of change. Thus, in a railroad or rapid transit system, for instance, it is desirable to maintain accurate identification and monitoring of the location of individual railroad cars comprising the moving stock of the system. Additionally, with respect to large stock inventories, it is desirable to maintain an accurate locator system for specific items or groups of items in an inven tory which is being continuously updated and/or moved about.
Another example of a significant need for passive identification systems is in traditional farm activities, such as beef cattle farms and dairy farms. Particularly in the large beef feed lots, where cattle are typically fattened up on a special diet for several weeks before they are slaughtered, it is desirable to maintain accurate records concerning the weight growth of individual cattle with respect to the amount and kind of food they are eating. Currently, records are kept, if at all, by human observation and hand recording. Automated types of identification systems to date have either been too expensive or too bulky to place on the individual animals. With respect to beef cattle, it is currently necessary to individually weigh the cattle and maintain weight records by hand. Identification of individual cattle and recording of growth by these methods have led to errors. Because of these errors and the inherent cumbersomeness of the methods, there exists a significant uncertainty with respect to the maximization of further weight gain of individual cattle with respect to the cost of additional feed.
Thus, with respect to the beef cattle industry, the dairy industry, railroad and mass transit industries, and other industrial situations involving large inventories of individual items, there is a need for an identification system which is inexpensive, reliable and small enough not to interfere with the movement of the animals or articles in the monitored system.
In accordance with the above, it is a general object of the present invention to provide a passive identification system which overcomes the disadvantages of the prior art.
Another object of the present invention is to provide a passive identification system responder which is small enough to be located on the article to be identified without interfering with its use or activities.
Another object of the present invention is to provide a passive identification system responder which does not require its own power source.
Other and further objects, features and advantages will become apparent as the description proceeds.
SUMMARY OF THE INVENTION Accordingly, the invention is a passive responder for use in a particular identification system. The responder 0 includes generally an antenna to receive a series of stepped frequencies from a system transceiver, a transmission line connected to the antenna along which the received frequencies are propagated, and a plurality of coupling means which are aligned along the transmission line and which are individually arranged such that the signal energy present at the received frequencies is coupled into selected ones of the associated couplers. The signal energy present at those received frequencies which do not have an operable associated filter continues along the transmission line to a second antenna, from which it is retransmitted to the transceiver for processing and pattern identification.
DESCRIPTION OF THE DRAWINGS A more thorough understanding of the invention may be obtained by a study of the following detailed description taken in conjunction with the accompanying drawings in which:
FIG. 1 is a block diagram of the transceiver portion of the passive identification system.
FIG. 2 is a signal diagram showing the relationships between the transmitted and received signals for a given responder code.
FIG. 3 is a signal diagram of the output of one stage of the transceiver portion of the passive identification system.
FIG. 4 is a pictorial representation of the responder portion of the passive identification system.
FIG. 5 is a diagram of one directional ring filter used in the responder.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 1 and 4, diagrams of a transceiver l0 and a responder 20 of the passive identification system of the present invention are shown. The transceiver 10 (FIG. I which is located typically at a fixed position in the identification system, uses a voltage controlled oscillator 11 under the control of logic circuitry 12 to generate a series of frequencies in the microwave range. The signal energy generated by the VCO sweeps through a predetermined octave range of frequencies or spectrum, the transmitted signal frequencies 15 varying in successive steps within that frequency octave range.
This swept spectrum signal energy is transmitted to a selected individual responder unit 20, which is located on the animal or other article which is to be identified within the system. The responder must be within the effective range of the transceiver, on the order of five to ten feet. Each animal or article in the system is provided with its own responder unit. The output of the VCO 11 is, simultaneously with transmission to the responder 20, applied to a multiplier 13, which doubles each signal frequency in the swept spectrum output of VCO II, the output of the multiplier 13 in turn being applied to a mixer 14. A local oscillator 16 supplies a second input to the mixer 14. The output of the mixer 14 (sum and difference frequencies) is applied to a filter 17, where the difference frequencies are removed, the output of filter l7 typically being the doubled VCO spectrum frequencies plus the frequency of the local oscillator 16. This series of signals is applied to a second mixer 18, the other input 19 of which is a signal re ceived from the responder unit 20 (not shown in FIG. 1) which initially received the transmission 12 from the transceiver.
The operation of the responder 20 and the characteristics of the signal 19 from the responder 20 to mixer 18 will now be briefly explained, and in more detail in following paragraphs. The signal energy from the VCO 11 is, as explained above, transmitted to a given responder unit 20 such as shown in H6. 4. The swept spectrum signal energy is received by a receiving antenna 21 and applied down a transmission line 22 to a diode frequency multiplier 23, which doubles all of the frequencies in the received swept frequency signal. The doubled signals are then transmitted back along the transmission line 22, where they encounter a series of directional ring filters, 26 -26,, which are successively positioned along the transmission line, and successively tuned to the individual frequencies comprising the now doubled swept frequency spectrum. if a given directional ring filter is tuned to a particular frequency present in the swept spectrum, the signal energy present in the transmission line at that frequency will be coupled into the ring, from which it is coupled into a load 27 and there dissipated.
Typically, each frequency in the doubled swept spectrum has an associated ring filter positioned along transmission line 22. However, selected ring filters may be physically distorted, thereby preventing the coupling of signal energy present at that frequency into the ring. The signal energy present at those predetermined frequencies continues back along the transmission line 22 and is reradiated by a transmitting antenna 28 back to the transceiver 10. This transmitted signal 19 from the responder is a plurality of predetermined doubled frequency signals, comprising those frequencies which were not coupled into their associated filter rings.
The signal energy radiated by responder 20 is received by transceiver 10 and applied to mixer 18 (FIG. 1). The output of mixer 18 (sum and difference frequencies) is filtered by filter 31, resulting in the difference frequencies between the output of filter 17 and responder signal 19 being applied to a conventional detector 32, which determines which frequencies are absent from the original spectrum of doubled transmitted frequencies, and which frequencies are still present. The output of the detector 18 is then applied to a comparator 33 which compares the output of detector 32 with a clock 34 output. The comparator 33 assigns ones and zeros to the individual positions, in time, of the frequencies of the original swept frequency signal 15, depending on whether a received frequency is present or absent with respect to the original transmitted signal. The comparator thus generates a digital word, the value of which is dependent upon the action of the responder ring filters 26 -26,. The output of the comparator 33 is applied to an appropriate display 35 or other processing apparatus for identification or record keeping of the article or animal bearing the responder unit.
More specifically, referring to FIG. 1, the voltage controlled oscillator (VCO) 11 generates a series of stepped frequencies within a single frequency octave, referred to as a swept frequency spectrum. The generated signals are in the microwave frequency ran ge, with a typical frequency octave coverage being between 2 and 4 gigahertz.
The number of discrete frequencies within the frequency octave is a function of the size (in terms of bits) of the digital word required to uniquely identify every article or animal in the system, and also depends to an extent upon current technological limits with respect to minimum frequency separation to maintain adequate ring filter coupling in the responder units. In the present invention a 2.6 percent frequency spacing is maintained between successive frequencies in the swept frequency spectrum transmitted to the responder. A closer spacing may be achieved with current technology, although the 2.6 percent spacing results in a suitable safety factor for coupling purposes in the responder. A sufficient number of individual frequencies are present with this spacing in the 2 to 4 gigahertz frequency range to allow for a digital identification word having a 26-bit capacity (n=26 in FIG. 4). Thus, the number of individual elements which can be uniquely identified in such a system is 2, a number sufficiently large to handle any contemplated system size at the present time.
Within the given octave frequency range of 2 to 4 gigahertz, the individual frequencies are generated by the VCO 11 under the direction and control of the logic and control circuitry 12, typically from the high frequency in the octave through the low frequency, at a predetermined rate. Typically, the repetition rate for the sweeping of the frequencies within the given range will be between and 1,000 repetitions per second. Other repetition rates, however, may be utilized, depending on the particular application.
The swept frequency spectrum generated by the VCO 11 is simultaneously transmitted to a responder unit and applied to a X2 multiplier circuit 13 in the transceiver 10. The transmitted signal typically has an effective range of between 5 and 10 feet. The responder unit (FIG. 4) is sufficiently small to easily fit under the skin of animals, such as cattle or the like, or they may be easily secured to articles in an inventory system. The size of the responder unit 20 is approximately 1% inches long by V2 inch wide by V4 of an inch deep when a substrate material with a dialectric constant of 40 is used. Material of other dialectric constants, tag. 20, may be used, although this would increase the size of the responder. The circuitry on the substrate, e.g., the transmission lines and ring filters, are comprised of gold which has been deposited and then selectively etched. It is a fully passive responder in that'it has no power source of its own, but rather utilizes the signals from the transceiver 10 for power to transmit the appropriate signals back to the transceiver.
In use, signal energy radiated from the transceiver 10 will impinge on a standard slot antenna 21 in the responder unit 20. The signal energy transmitted by the transceiver l0 and picked up by the slot antenna 21 is applied down a transmission line 22 in the responder 20 to a diode multiplier 23, which functions as a harmonic frequency generator. This diode multiplier 23 doubles the frequency of each individual frequency in the transmitted spectrum received by antenna 21.
This frequency doubling, which is also accomplished in the transceiver by multiplier 13, allows for significantly more precise and clearer reception by the transceiver 10 of energy transmitted by the responder 20. Any background noise present at the transceiver 10 which is reflected by the animal or article bearing the responder unit may be effectively filtered out, because the reflected signal energy will be at the original trans mitted frequencies. Transmitted signal energy from the responder unit 20, being frequency doubled, is thus easily ascertained and detected by the transceiver.
After the frequencies present in the swept frequency spectrum are doubled by the diode multiplier 23, approximately 10 percent of the initial impinging signal energy on the diode multiplier 23 is transmitted back along transmission line 22. Arranged along both sides of transmission line 22 are a series of directional ring filters, 26 -26 as shown in FIG. 5. Each ring filter has a length equal to the wavelength of one of the doubled frequencies, although, as mentioned above, selected filters are inoperative due to a severing of the ring. Signal energy at those frequencies which have an operable associated ring filter is coupled into those filters, while the remaining energy continues along the transmission line. The ring filters tuned to the highest frequency in the spectrum are nearest the diode multiplier 23 and successively located rings are tuned to successively lower frequencies, until the rings 26 and 26,, nearest the slot antenna 21 are tuned to the lowest frequencies present in the spectrum.
When the signal energy is transmitted back along the transmission path 22, the energy present at the individual frequencies in the spectrum, as discussed above, will be coupled into their associated directional ring filters. Additional transmission lines 37 are provided on the outer sides of the ring filters, such that the energy present in the tuned rings may be coupled into a load 27 and dissipated. This coupling and subsequent dissipation of energy at selected frequencies in the doubled frequency spectrum occurs when there is a first coupling between the transmission line 22 (see FIG. 5) and a ring filter 26 which is tuned to one of the spectrum frequencies, and a second coupling from ring 26 to transmission line 37 into load 27. However, for those frequencies which are not coupled, because the ring filter is physically broken or inoperable because of some other reason, the associated signal energy will continue along the transmission line 22 back to transmitting antenna 28, where it is transmitted back to the transceiver 10.
Referring to FIG. 2, a transmit-receive signal diagram is shown for an original spectrum comprising six fre quencies f f.,-, and a given responder ring configuration. The solid stepped line 41 is representative of the frequency spectrum of the signal transmitted by the transceiver (doubled), which is thus substantially the signal spectrum reflected back from the diode converter 23 in responder 20, while the dashed line 42 indicates the frequency spectrum of the signal transmitted by the responder 20. The sharp dips in the signal from the responder indicate an absence of signal energy at those frequencies.
The spectrum "openings" at F and F in the signal from the responder are demonstrated by the dashed lines of FIG. 2. The slight separation between the solid line and dashed line in FIG. 2 are for purposes of explanation clarity only. The dashed lines of FIG. 2 show that, at predetermined frequencies, no signal energy is radiated back toward the transceiver 11 by the responder 20. Each responder unit in the system has a different configuration of complete versus incomplete ring filters, such that each responder will radiate a unique pattern of energy back to the transceiver with respect to the originally transmitted frequency spectrum.
Referring again to FIG. I, the energy radiated back from the responder unit 20 (not shown) to the transceiver 10 is applied as one input 19 to mixer 18. The other input to mixer 18 is the output of filter 17. The source of this output signal is VCO 11, the output of which is applied to a X2 multiplier circuit 13, which doubles all the frequencies in the swept frequency spectrum generated by the VCO 11, identically to that of the diode converter 23 in the responder 20. Thus, the output of the multiplier 13 in transceiver I0 is substantially identical in frequency coverage with the output of the diode converter 23 in the responder 20.
The output of multiplier 13 is applied as one input to a conventional mixer 14, which, in combination with the signal from local oscillator 16, provides a frequency offset of the multiplied frequency spectrum output from multiplier 13, thereby resulting in improved recognition by the transceiver of the signal 19 from exist ing background noise. The local oscillator 16, under the control of logic and control circuit 12., generates a signal having a frequency on the order of 30 megacycles. The output of the mixer 14 is the sum and difference frequencies between the doubled frequency signals from the multiplier 13 and the frequency of the local oscillator 16. The sum and difference frequencies are then applied to a filter circuit 17, which typically filters out the high frequencies, e.g., sum frequencies, and passes the low frequencies, e.g., difference frequencies, to mixer 18. Thus, if the output of the VCO 11 at any one point in the frequency spectrum is arbitrarily defined as F the output of multiplier 13 at that frequency point will be 2F the output of mixer 14 will be 21% r 30 megahertz, and the output of filter 17 will be 2F 30 megahertz. F in the present invention would be in the range of 2-4 gigahertz.
As mentioned above, the other input to mixer 18 is the signal 19 transmitted by the responder 20, which signal is the doubled frequency spectrum similar to the output of filter 17, except with energy openings" at those frequencies where energy was coupled away from transmission line 22 in the responder 20 by complete filter rings. This predetermined deletion of energy at certain frequencies may be considered to be a type of modulation of the responder doubled frequency spectrum. The signal 19 present at mixer 18 at any frequency F can then be defined as 2F plus the responder modulation at that frequency. The output of mixer 18 will be the sum and difference frequencies between the two inputs. Filter 31 will remove the sum frequencies, and provide as an output the difference frequencies. Thus, the output signal frequency of filter 31 at each step in the spectrum will be equal to 21'], 3O megahertz (2E, modulation), where F refers to the original VCO frequency of each step. Referring to FIG. 3. the idealized output of the filter 18, in terms of amplitude v. time. is shown for the frequency response diagram of FIG. 2.
The output of filter 3| depends on the presence or absence of returning frequency energy from the responder 20 at the successive doubled spectrum fre quencies. The presence of energy at a particular frequency in the signal from the responder, when mixed in mixer 18 with the output of filter 17 will result in a small frequency difference signal L in that time slot of the spectrum equal to the frequency output of local oscillator 16. In operation, it is significantly easier to detect lower power signals, such as those typically transmitted by the responder, when the mixer 18 output is not allowed to go to DC. Thus, the local oscillator 16 forces the output of the mixer 18 to be always offset from the DC level, thus making the received signal easier to detect from the background noise.
Referring to FIGS. 2 and 3, the presence of energy at a particular frequency in the signal transmitted by a responder will result in the output of filter 31 during that time period being a small amplitude signal having a frequency L equal to that of the local oscillator, as ex plained above. However, when there is an absence of energy at a particular frequency in the responder transmitted signal, such as shown for frequency f in FIG. 2, indicating that energy at that frequency has been coupled into its associated ring filter in the responder and dissipated, the amplitude of the difference frequency output of the filter 31 will increase significantly, as shown.
The presence of energy at a particular frequency in the signal transmitted by the responder 20 will thus result in a low amplitude, small frequency signal, which may be conveniently defined as a binary zero, While the absence of energy at a particular frequency in the signal from the responder will result in a relatively high amplitude output at that frequency, which signal may be conveniently defined as a binary one.
The output of filter 31 is applied to a detector 32, (FIG, I) which distinguishes in time the large amplitude pulse one" output from the low amplitude zero" output. The output of detector 32 is then ap plied to a comparator circuit 33 which compares the output of detector 32 with a clock signal having a predetermined frequency and amplitude from clock circuit 34. The comparator 33 assigns a one to the time slot in the spectrum where a large amplitude pulse appears and assigns a zero" to that time slot in the spec trum where no pulse appears. Thus, a digital word is created with ones" corresponding to an absence of signal energy from the responder at a particular frequency in the spectrum, and zeros" corresponding to a presence of signal energy from the responder at a particular frequency. This arrangement may, of course, be inverted for convenience Thus, the digital word for the example of FIGS. 2 and 3 would be 010010. This digital word. .vl'llCl'l uniquely identifies a particular responder and hence the animal or article on which it is located with respect to all other responders in the system, is then applied to standard display circuitry 35. The display circuitry typically consists of either visual display means, such as neon tubes or the like, or a printing de vice, for readout of the actual number of the animal or article being identified. Additionally, the number may be applied to a computer for processing of individual records For instance, if an animal is weighed automatically immediately after it is identified, a computer can be used to address the animal's weight records, and the weight measured may then be entered immediately into the animals records. Evaluation of growth rate versus feed costs for a particular animal may then be easily made, so as to maximize decisions regarding the animals future feeding, and to determine the most appro priate time to put the animal to market.
Thus, a system has been described which is capable of uniquely identifying one animal or article from a large number of similar animals or articles. Each article bears a passive responder device, which, in conjunction with a single transceiver, is capable of uniquely identi fying its bearer. This allows for identification of animals and articles in an accurate and inexpensive manner.
Although a preferred embodiment of the invention has been disclosed herein for purposes of illustration, it should be understood that various changes, modifications and substitutions may be incorporated in such embodiment without departing from the spirit of the invention as defined by the claims which follow.

THE fire service says that the acid in the chemical drum is under control and the public is in no danger following the incident in Sutton earlier this morning.
Tests are ongoing to determine the exact nature of the substance but no one has been evacuated and no safety measures have been put in place.
ROBINS Lane has been closed after steam was seen pouring out of a chemical drum at the side of the road.
Firefighters were called at 7.41am to discover a five gallon drum lying in the gutter.
A safety cordon has been put in place and firefighters wearing gas suits are carrying out an inspection.
They also placed special mats over drains near the drum to prevent any of the substance entering the drain.
Specialist fire officers are on scene to identify the substance.
Two fire appliances are at Robins Lane close to Ellen Street along with the Incident Management Team.
A council spokesman said that no schools have been closed.

There's a new theory making the rounds on the internet about the disappearance of Malaysia Airlines Flight 370, and unlike Brandon Wenerd's stupidly logical scenario, this one's got some grounding.
Did Pitbull make the plane go disappear?
We're not saying he's personally responsible, but intrepid YouTubers noticed some similarity between lyrics in his song 'Get It Started' and what happened 11 days ago.
The lyrics go:
No Ali, no Frasier, but for now it's off to Malaysia
Two passports, three cities, two countries, one day
Now that's worldwide, if you think it's a game, let's play, dale
Let's break it down.
Some would say No Ali is referencing the famous boxer. But the co-pilots name was fAriq abduL HamId. A L I. And now he's gone. No Ali.
Two passports is much more clear. The two Iranian men who boarded with two fake passports. Three cities. Kuala Lumpur, Beijing and whatever city the plane is hidden in now. Two countries. Malaysia and China (furthering Slate's theory that the plane is in Northern China).
Now that's worldwide. The hunt is now worldwide. And Pitbull's saying it ain't no game.
Shit just got real.

New Orleans Restaurants
Gautreau's Review
This vine-covered neighborhood bistro doesn't have a sign, but that hasn't stopped the national food media from finding it. Lauded chef Sue Zemanick cooks with elegant confidence in a classic French style, but with surprising bursts of understated creativity, evidenced in dishes like seared tuna with peach salsa and fried plantains. At Gautreau's, even the simple roasted chicken satisfies, and everyone should indulge in the caramelized banana split at least once. An older crowd of well-dressed regulars monopolizes most of the tables in this dark, quiet space that once housed a pharmacy, but if you can get a reservation, you'll feel like you've gained admittance to an elite club.
