Title: The Innovations of James H. Leveque
Introduction
James H. Leveque is a notable inventor based in Ellicott City, MD (US). He holds a total of 5 patents that showcase his contributions to telecommunications technology. His work has significantly impacted the field, particularly in noise reduction and signal processing.
Latest Patents
One of his latest patents is the "Trunk Dialing Converter." This invention includes a digital FSK trunk dialing converter with M and E lead control. It features an FSK detector that responds to consecutive half-period intervals of a received FSK signal. Additionally, it incorporates a digital signal-to-noise (S/N) detector that inhibits the E-wire signal lead in the presence of noise signals. The FSK detector consists of two digital circuits that generate pulses to indicate whether the received FSK signal is above or below the center frequency. These pulses are integrated to trigger a flip-flop, providing a demodulated digital FSK output.
Another significant patent is the "Method and Apparatus for Reducing Noise in a Linked Compressor-Expander." This invention addresses noise fluctuation in a linked compressor-expander telecommunications system. It involves injecting an artificial tone signal into the demodulator to bias the output toward self-quieting. The artificial tone is designed to be effective below a threshold level, ensuring that it does not negatively impact normal communication transmission.
