Title: Mark A Rosswurm: Innovator in Microprocessor Control Systems

Introduction

Mark A Rosswurm is a notable inventor based in Ada, OH (US). He has made significant contributions to the field of microprocessor control systems, holding a total of 4 patents. His innovative work focuses on enhancing the reliability and functionality of electronic control units.

Latest Patents

One of his latest patents is the "Random pattern lock and key fault detection scheme for microprocessor." This invention utilizes a microprocessor-based electronic control unit that detects failures in the system being controlled or the control unit itself. The system is programmed to receive a random data word and output the same data word while performing various tests. This results in a data stream that can be combined with the random data word to form a predetermined data word necessary for maintaining microprocessor control. If the microprocessor fails to generate the correct data stream, the control unit output is locked into a predetermined state.

Another significant patent is the "Tracking filter for sensing DC content in an AC waveform." This invention detects the DC content of an AC waveform using a digital filter that partially filters each phase of the waveform. The filtered waveforms are applied sequentially through a multiplexer to a sample and hold circuit, which measures the instantaneous value of each phase at two points spaced an exact odd number of half cycles apart. The measured values are processed by a microprocessor system to generate a signal corresponding to the DC content for each phase.
