Title: The Innovations of Raymond J. Wilfinger

Introduction

Raymond J. Wilfinger is a notable inventor based in Lagrangeville, NY (US). He holds a total of 5 patents that showcase his contributions to the field of technology. His work primarily focuses on advancements in optical and electronic systems.

Latest Patents

One of Wilfinger's latest patents is the "Solid State Electro-Optical Track Follower Array." This invention involves directing reflected light from an optical disk player at a string of photo-sensitive diodes. The outputs from two adjacent diodes are summed to generate the output signal for the optical disk player. Additionally, the outputs are subtracted to create a differential signal for tracking purposes. This differential output helps in determining how much light from the selected portion of the track reaches each diode. When the differential output exceeds a preselected value, the decode circuitry adjusts the combination of adjacent diodes to generate the necessary video output signal and difference signals.

Another significant patent is the "Universal Transversal Filter Chip." This specification describes a charge-transfer device transversal filter chip that processes an input signal in parallel across multiple channels. Each channel contains an analog shift register, a signal splitter, and a polarity selector. The unequal lengths of the shift registers provide different delays through each channel, while the signal splitter creates multiple signal paths. The polarity selector determines whether a path in a channel is added or subtracted during the summation, influencing the gain of that channel.
