Title: The Innovations of Robert L. Nelson, Jr.
Introduction
Robert L. Nelson, Jr. is an accomplished inventor based in Austin, TX. He has made significant contributions to the fields of pressure sensing and digital signal processing. With a total of 2 patents to his name, his work showcases a blend of mechanical and electrical engineering principles.
Latest Patents
One of his latest patents is a pressure sensor that features a mechanical part with a fluid pressure chamber. This chamber includes a magnetic, electrically conductive diaphragm that moves in response to pressure changes. The diaphragm makes contact with a stationary contact when pressure is absent or when energized by a magnetic coil. The electrical circuit connected to the coil utilizes a clocked flip-flop, which outputs a high signal when the contacts are open and a low signal when they are closed. This innovative design allows for a digital measurement of pressure that can be easily integrated into computer systems.
Another notable patent is a digital phase detector and method. This invention includes a hard limiter that converts an incoming signal of known frequency into a binary signal. A reference generator produces two binary references at the same frequency, with one reference shifted 90 degrees in phase. The binary signal is then exclusive-ORed with each reference, controlling two counters that register counts analogous to trigonometric functions of the signal phase angle. This design incorporates a phase modulated clock, allowing for corrections to be made for errors introduced by the quantized nature of digital computations.
