Abstract

Short range communication systems and techniques are described. In an implementation an interrogator held near a person interrogates multiple transponders and receives information separately from the transponders. The interrogator and/or the transponders may be held in an article of clothing or in a personal effect of the person. The transponders may transmit identifying information and/or information associated with the states of the articles of clothing or personal effects of the person. Such a system enables the clothes worn by a person to communicate with a plurality of items and obtain useful information. In addition, a network system may be configured so that any particular transponder may communicate with another transponder or group of transponders of other locales to activate functions, cause actions or otherwise share data and/or information.

Claims

1. A method comprising:

carrying signals associated with an interrogator and transponder in conductive elements in at least two different articles of clothing or personal effects, and

transferring the signals between the at least two articles of clothing or personals effects radiatively.

2. The method of claim 1 in which the conductive elements comprise electrical conductors.

3. The method of claim 1 in which the conductive elements comprise insulated wires.

4. The method of claim 1 in which the conductive elements comprise insulated conductive fibers.

5. The method of claim 1 in which the articles of clothing or personal effects comprise at least one of pants, shirt, jackets, coats, earphones, glasses, listening devices, necklaces, rings, watches, bracelets, hats, walking sticks, hockey sticks, shoes, ties, underwear, outerwear, pens, pencils, personal digital assistant devices, laptop computer, desktop computer, bags, backpacks, luggage, wallets, money clips, timepieces, wristwatches, cell phone, desk phones, pedometers, temperature sensors, global positioning devices, environmental sensors, biological sensors, whether worn on the garments or below the epidermal skin layer of the human body or embedded or mobile within the human body, fitness devices, and other appliances and equipment.

6. A short-range communication system, comprising;

an interrogator,

a first network of coupling ports in a first material;

a web of communication lines in the first material connecting the first network;

a second network of coupling ports in a second material;

a web of communication lines in the second material connected to the networks; and

transponders for establishing communication with the first and second networks and with the interrogator.

7. The system of claim 6, further comprising electronic components and circuitry to increase the sensitivity of the coupling ports.

8. The system of claim 6, further comprising at least a third network of coupling ports in a third material and a web of communication lines connecting the third network, wherein transponders are operable to communicate with any of the networks and with the interrogator.

9. A method of extending the range of a short-range communication system, comprising;

installing a first network of coupling ports in a second material; and

installing a second network of coupling ports in a second material; and

installing a plurality of communications lines in the first and second materials such that communications are possible between coupling ports of the first and second networks.

10. The method of claim 9, further comprising installing at least one electronic component to increase the sensitivity of at least one coupling port.

11. The method of claim 9, further comprising utilizing transponders to communicate with the coupling ports, at least one of the transponders configured to transmit activation signals.
