Title: Alan Gordon: Innovator in Acoustic Telemetry
Introduction
Alan Gordon is a notable inventor based in San Diego, CA (US). He has made significant contributions to the field of acoustic telemetry, holding a total of 4 patents. His work focuses on improving data transmission capabilities in undersea communications systems.
Latest Patents
One of his latest patents is the Precision Doppler Effect Compensator. This invention provides Doppler compensation in acoustic transmission by simultaneously sending a known reference signal along with an information signal. Both signals undergo identical Doppler effects, allowing the compensator to use the Doppler-shifted reference signal to sample the analog Doppler-affected information signal. The analog information signals are then digitally converted and stored in a first-in-first-out (FIFO) shift register. The samples are read out at a rate corresponding to the frequency of a non-Doppler shifted reference signal, enabling precise reconstruction of the transmitted information signal. The samples are reconverted from digital to analog form for further processing by a receiving modem.
Another significant patent is the Synchronous/Asynchronous Independent Single Sideband Acoustic Telemetry. This undersea communications system enhances data transmission capabilities by allowing two separate sources of information to modulate the upper and lower sidebands of an acoustic carrier. The discretely modulated sidebands can be transmitted simultaneously without the acoustic carrier, or the carrier can be added for asynchronous or synchronous demodulation. The separation of information in the two sidebands is achieved by shifting the modulating information to ultrasonic regions and filtering out the upper and lower sidebands. A phase-locked loop in the receiver ensures synchronous demodulation, while a crystal oscillator allows for asynchronous demodulation.
