Title: The Innovative Contributions of David Glenn Lashley

Introduction

David Glenn Lashley is a notable inventor based in Cartersville, Georgia, with a remarkable portfolio of 11 patents. His work primarily focuses on advancements in telecommunications, particularly in enhancing the functionality and performance of amplified telephones.

Latest Patents

Among his latest innovations is the patent for "Adaptive Duplexing for Amplified Telephone." This invention presents systems and methods aimed at reducing squealing or feedback on amplified telephones. The telephone system includes a receiver in communication with a receive signal path and a transmitter in communication with a transmit signal path. A receiver gain detector is configured to detect the receiver gain on the receive signal path. The controller operates the telephone system in full duplex when the receiver gain is approximately less than a receiver stability level and switches to adaptive duplex when the receiver gain exceeds this level. The adaptive duplex mode applies an attenuation level alternately on the receive and transmit signal paths, depending on how much the receiver gain surpasses the stability level.

Another significant patent is for an "Isolated High Gain Line Amplifier Circuit." This invention includes a first and second microphone transmit line, along with a light-emitting diode that has a controllable variable light output. A photo-resistor cell is coupled across the microphone transmit lines and is designed to attenuate gain on these lines in response to the light output from the diode.
