Title: The Innovations of Douglas Edward Sherry

Introduction

Douglas Edward Sherry, an inventive mind based in Mertztown, Pennsylvania, has made significant contributions to technology through his innovative patents. With a total of two patents to his name, Sherry has demonstrated his expertise in electrical engineering and signal processing.

Latest Patents

One of Sherry's latest patents is the "Apparatus for Detecting Clock Failure within a Fixed Number of Cycles of the Clock." This invention involves a loss-of-clock (LOC) detector circuit that efficiently identifies clock failures within a specified range of clock periods. It generates a loss-of-clock signal, which is vital for maintaining the integrity of electronic systems. The LOC detector utilizes a frequency-to-current converter that produces a charging current in proportion to the input clock frequency, alongside a capacitor to monitor voltage changes. An edge detector processes the input clock signal and a switch, controlled by the edge detector, allows for proper discharging of the capacitor, ultimately triggering a comparator to signal a loss-of-clock condition.

Another noteworthy patent of Sherry's is the "MPSK Demodulator." This invention focuses on decoding passband signal pulses transmitted using an M-ARY phase shift keying modulation scheme. The receiver includes a multiphase sampler that generates digital words representing the phase of sampled pulses, enabling accurate decoding of the transmitted signal. A phase reference register stores one digital word as a reference, facilitating the comparison required for decoding the rest of the signals.
