REMOTE COMMUNICATION AND CONTROL OF ACOUSTIC DETECTORS
First Claim
1. A control system for controlling a function of an acoustic detector, comprising:
- a memory that stores a reference power spectrum of a reference acoustic signal, the reference power spectrum being associated with a mode of operation of the acoustic detector;
a receiver including an analog signal conditioning circuit that receives an acoustic sound signal, the acoustic signal includes a tone and harmonic tones; and
a detector that performs the mode of operation when a comparison of the real-time acoustic power spectrum with the reference acoustic power spectrum indicates that the acoustic sound signal is a control signal;
wherein the receiver generates a real-time acoustic power spectrum in response to the receiving of the acoustic sound signal.

Abstract
A method of controlling a function of an acoustic detector includes storing a reference power spectrum of a reference acoustic signal, the reference power spectrum being associated with a mode of operation of the acoustic detector; receiving an acoustic sound signal, the acoustic sound signal including a tone and harmonic tones; generating a real-time acoustic power spectrum of the acoustic sound signal responsive to the receiving of the acoustic sound signal; and performing the mode of operation when a comparison of the real-time acoustic power spectrum with the reference acoustic power spectrum indicates that the acoustic sound signal is a control signal.
