Wireless identification system using a directed-energy device as a tag reader
First Claim
1. A wireless identification system, comprising:
- a directed-energy device configured as a reader, comprising;
a charged particle generator configured to generate plural energized particles; and
a charge transformer configured to receive the plural energized particles that include charged particles from the charged particle generator and to output a wavefront including energized particles that include particles having substantially zero charge;
andan identification tag configured to be activated when impinged by the wavefront from the reader so as to transmit a signal configured to be used by the reader.

Abstract
A wireless identification system can include a directed-energy device configured as a reader. The reader can include a charged particle generator configured to generate energized particles and a charge transformer configured to receive the energized particles that include charged particles from the charged particle generator and to output a wavefront including energized particles that include particles having substantially zero charge. The system can also include an identification tag configured to be activated when impinged by the wavefront from the reader so as to transmit a signal configured to be used by the reader. A method of using a directed-energy device as a tag reader in a wireless identification system can include generating a wavefront that includes particles at substantially zero charge, impinging an identification tag with the wavefront so as to activate the identification tag so as to send a signal and detecting a signal transmitted by the identification tag.

27. A method of using a directed-energy device as a tag reader in a wireless identification system, comprising:
-
generating a wavefront that includes particles at substantially zero charge; impinging an identification tag with the wavefront so as to activate the identification tag so as to send a signal; and detecting a signal transmitted by the identification tag; wherein generating the wavefront that includes particles at substantially zero charge comprises; generating an RF signal; combining the RF signal with an excitation signal to produce a modulated signal; generating a modulated photon wave associated with the modulated signal, the modulated photon wave including plural energized particles; directing the modulated photon wave to an incident surface of a charge transformer; transforming the plural energized particles within the charge transformer, wherein the transformed particles are at substantially zero charge; and generating a wavefront at an exit surface of the charge transformer that includes the transformed particles at substantially zero charge. - View Dependent Claims (28, 29)
