Title: Donald C. Lokerson: Patents in Satellite Communications and Speech Analysis.
Introduction
Donald C. Lokerson is an inventor associated with New Carrollton, Maryland. His work spans optical satellite communications and speech-signal analysis. He is credited with 2 patents.
Latest Patents
**Multi-Access Laser Communications Transceiver System.** This invention describes an optical communications network in which as many as six low Earth orbiting satellites send data to a geosynchronous satellite, which relays it to a ground station. The geosynchronous satellite terminal uses a ring assembly and pivoting arms to track individual satellites without a gimbal, positioning optical pickups for communication.
**Speech Analyzer.** This invention analyzes speech using formant filters and pulse trains that represent characteristics of the first, second, and third formants. It normalizes selected pulse trains against the second-formant signal, then supplies the resulting data to memory for phoneme identification or transmits it as a narrow-bandwidth signal.
Career Highlights
Lokerson’s listed patent work connects two distinct technical fields: satellite-based laser communications and the electronic analysis of speech. The supplied information associates his work with the United States of America, represented by the Administrator of NASA, and Laser Data Technology, Inc.
Collaborations
The provided information names Daniel D. Meyer and Monte Ross as Lokerson’s coworkers.
Conclusion
Donald C. Lokerson’s two patents reflect inventive contributions to optical links between satellites and automated speech analysis.
