Title: Michael A Clark: Innovator in Vehicle Detection and Modulation Technologies
Introduction
Michael A Clark is a notable inventor based in Southampton, GB. He has made significant contributions to the fields of vehicle detection and modulation technologies. With a total of 4 patents to his name, Clark's innovations have had a lasting impact on the industry.
Latest Patents
One of his latest patents is the Induction Loop Vehicle Detector. This device comprises an oscillator circuit with multiple capacitors that are switchable in circuit with a road loop. The control of this system is managed by a microcomputer, which determines the oscillator frequency. The microcomputer monitors the frequency and controls the switching of the capacitors to maintain a predetermined value. A counter counts a specific number of oscillator cycles, and the output indicates when a vehicle is detected based on changes in the inductance of the loop.
Another significant patent is the Phase Modulator Circuit. This invention addresses the issue of noise generated during the modulation of high-frequency signals with audio frequency signals. To mitigate this problem, a fast ramp signal is generated by charging a low-value capacitor from a constant current source. The ramp signal is then applied to a level detector, which produces an output edge signal when the ramp signal crosses a defined switching level.
