Electromagnetic tags
View Patent ↗An electromagnetic tag includes a communication component, which includes an optical transmitter/emitter that transmits/emits optically encoded information.
1. An electromagnetic tag, comprising:
a communication component, including
an optical transmitter/emitter that transmits/emits optically encoded information; and
an optical receiver that detects at least one of an optically encoded signal including at least one of a request, a query, an instruction, an application, data, an algorithm, and an activation command;
wherein the detected optically encoded signal includes authentication information.
2. The electromagnetic tag as set forth in claim 1 , wherein the optically encoded information transmitted/emitted by the optical emitter is at least one of modulated incident light and data stored within the electromagnetic tag.
3. The electromagnetic tag as set forth in claim 1 , wherein the optically encoded information is transmitted/emitted based on a predetermined frequency.
4. The electromagnetic tag as set forth in claim 1 , wherein the transmitted/emitted optically encoded information includes light within the visible or non-visible regions of the electromagnetic spectrum.
5. The electromagnetic tag as set forth in claim 1 , wherein the detected optically encoded signal includes a predetermined authorization pattern of at least one of one or more photons, bursts of photons, and streams of photons.
6. The electromagnetic tag as set forth in claim 1 , wherein the detected optically encoded signal invokes the optical transmitter/emitter to transmit/emit the optically encoded information.
7. The electromagnetic tag as set forth in claim 1 , further including a photo-detector that detects light from at least one of the visible and the non-visible regions of the electromagnetic spectrum.
8. The electromagnetic tag as set forth in claim 1 , wherein the communication component further transmits/emits at least one of electrically and mechanically encoded information.
9. The electromagnetic tag as set forth in claim 1 , further including an optical power element that derives power from light and powers the components of the electromagnetic tag.
10. The electromagnetic tag as set forth in claim 1 , further including a presentation component that provides at least one of visual, audible, thermal, and tactile information.
11. The electromagnetic tag as set forth in claim 10 , wherein the presentation component includes at least one of a light emitting diode (LED), a liquid crystal display (LCD), and a seven segment display.
12. The electromagnetic tag as set forth in claim 1 , further including at least one of radio frequency identification (RFID), contact smart card, magnetic card, and contactless smart card componentry.
13. An electromagnetic tag, comprising:
a transmitter/emitter that transmits/emits information; and
a power component that receives light, generates power from the received light, and provides the generated power to energize at least the transmitter/emitterU
an optical receiver that receives at least one of an optically encoded signal including at least one of a request, a query, an instruction, an application, data, an algorithm;
wherein the received optically encoded signal includes authentication information.
14. The electromagnetic tag as set forth in claim 13 , wherein the power component includes at least one a solar cell, a photo-voltaic cell, a photo-transducer, and a photo-diode for receiving the light and generating the power.
15. The electromagnetic tag as set forth in claim 13 , wherein the power component includes at least one of a rechargeable and a non-rechargeable battery that energizes at least the transmitter/emitter.
16. The electromagnetic tag as set forth in claim 13 , wherein the power generated by the power component charges an internal battery that energizes at least the transmitter/emitter.
17. The electromagnetic tag as set forth in claim 13 , wherein the transmitter/emitter transmits/emits at least optically encoded information.
18. An electromagnetic tag, comprising:
an optical receiver that receives optically encoded information;
an optical transmitter/emitter that transmits/emits optically encoded information; and
an optical power component that converts light into energy that powers the optical receiver and the optical transmitter/emitter;
wherein the received optically encoded information includes a predetermined authorization pattern of at least one of one or more photons, bursts of photons, and streams of photons.
