Passive voice-activated microphone and transceiver system
First Claim
1. A system for providing sound wave activated control of an electronic device, comprising:
- an interrogator unit for generating a signal and transmitting a pulse of the signal, for receiving a modulated signal, for determining a difference between the signal and the modulated signal corresponding to a sound wave signal containing instructions for controlling the electronic device, and for controlling the electronic device using the instructions of the sound wave signal; and
an acoustically driven microphone unit spaced from the interrogator unit, the acoustically driven microphone unit receiving the signal pulse from the interrogator unit, modulating the signal pulse with the sound wave signal to form the modulated signal and transmitting the modulated signal to the interrogator unit.

Abstract
A voice-activated microphone and transceiver system includes an interrogator unit for transmitting a signal, receiving a modulated signal, and demodulating the modulated signal such that the difference between the transmitted signal and the modulated signal correspond to a unique sound wave signal. An acoustically driven microphone unit is also included for receiving the signal from the interrogator unit, modulating the signal with the sound wave signal, wherein the sound wave signal contains instructions for controlling an electronic device, and transmitting the modulated signal back to the interrogator unit for analysis by a signal processor.
