Title: Michael F Jeffers: Innovator in Amplifier Circuits and Optical Communication
Introduction
Michael F Jeffers is a notable inventor based in Flourtown, PA (US). He holds a total of 4 patents that showcase his contributions to the fields of amplifier circuits and optical communication systems. His innovative work has significantly impacted the way signals are processed and transmitted.
Latest Patents
One of Jeffers' latest patents is an "Amplifier circuit with distortion cancellation." This invention involves a circuit designed to amplify an input signal while effectively canceling distortion. The output amplifier develops an output signal that includes distortion at a first magnitude and phase displacement. The circuit incorporates a further amplifier that operates at similar input and output levels, allowing for the cancellation of distortion in the output signal.
Another significant patent is the "Method and apparatus for redundant communication of optical signals." This invention provides a fiber optic communication system with parallel paths to cancel even order harmonic distortion components. The system utilizes a pair of parallel optical fibers, each connected to corresponding transmitters and receivers. The transmitters are modulated with input signals at a 180-degree phase differential, enabling the recovery of the input signal while canceling distortion products introduced by the transmitters.
