Title: David L Richardson: Innovator in Satellite Tracking Technology
Introduction
David L Richardson is a notable inventor based in Arlington Heights, IL (US). He holds a total of 13 patents that showcase his contributions to the field of technology, particularly in satellite tracking systems. His innovative designs have significantly advanced the capabilities of tracking technologies.
Latest Patents
One of his latest patents is the Energy Conserving Satellite Tracking Tag. This invention is designed to receive radio frequency location data signals from global positioning satellites and communicate with a tracking system. The tag features a receiver circuit, a customer ID module, a transponder circuit, and a power circuit that can connect to both a battery power supply and an external power source. Additionally, it includes a programmable microprocessor that collects and processes location data, identification signals, and command signals to produce a composite output signal. This output is then transmitted to the tracking system via a radio carrier wave.
Another significant patent is the Radio Tag for LFM Radar. This RFID system utilizes encoded digital information with pulsed linear frequency modulation (LFM). The LFM waveform is transmitted from an aircraft or satellite and received by a transponder. The system demodulates the waveform using both AM and FM receivers, validating and decoding the data against preprogrammed criteria. Algorithms within the transponder calculate frequency deviation and the direction of the LFM input signal, ensuring accurate data transmission.
