Title: The Innovations of John A Geen
Introduction
John A Geen is a notable inventor based in Wrentham, MA (US). He has made significant contributions to the field of sensor technology, holding a total of 3 patents. His work primarily focuses on advanced gyroscopic and accelerometer systems, which have applications in various industries.
Latest Patents
One of Geen's latest patents is the micromachined accelerometer gyroscope. This integrated rate and acceleration sensor features a substantially planar silicon body. The design includes a micro-silicon accelerometer that consists of a first frame and a proof mass suspended by flexures. The accelerometer has sensitive and rate axes that are orthogonally arranged. Additionally, the sensor incorporates a structure for dithering the proof mass along a dither axis, which is perpendicular to both the sensitive and rate axes. This innovative design utilizes interdigitated electrodes to exert electrostatic forces on the planar body, enhancing its functionality. Another significant patent is the multiple axis ring laser gyroscope with longitudinal excitation. This gyroscope employs RF excitation to induce gas discharge, differing from the conventional DC excitation used in traditional models. The external surfaces of the gyroscope's body are metallized to form electrodes, allowing for effective coupling of RF signals to the gas reservoirs.
