Title: The Innovations of Fred W. Caspari
Introduction
Fred W. Caspari is a notable inventor based in South Bend, Indiana, recognized for his contributions to technology with a total of four patents. His work primarily focuses on advancements in electronic systems, particularly in the fields of data decoding and television tuning.
Latest Patents
Among his latest patents, Caspari developed a microprocessor-controlled system for decoding serial data into parallel. This apparatus is designed to decode a serial data stream that includes remote control information. The system utilizes a microprocessor that samples data at a rate exceeding two times the data rate. It counts the number of consecutive samples of zero bits between samples of a one bit, loading a register with a one bit whenever a one is sampled, and a zero bit when the number of consecutive zeros exceeds a predetermined threshold.
Another significant invention is an electronic system for automatically tuning to a selected television. This all-electronic tuning system establishes the frequency of a local oscillator in a television receiver. Upon channel selection, a number representing the desired channel is entered into a memory circuit. A first plurality of frequencies is generated in response to the channel selection, causing a voltage-controlled oscillator (VCO) to increase in frequency. The system compares the VCO frequency with a second plurality of frequencies, recording a count when a predetermined difference exists. This count is then compared to the memory circuit to stabilize the VCO frequency until the next channel selection.
