Title: Craig J Cornelius: Innovator in Vibrating Beam Technology
Introduction
Craig J Cornelius is a notable inventor based in Redmond, WA (US). He has made significant contributions to the field of vibrating beam technology, holding a total of 3 patents. His work focuses on enhancing the performance and accuracy of transducers used in various applications.
Latest Patents
One of his latest patents is the "Vibrating Beam Transducer Drive System." This invention provides different excitation voltages to the separate beams of a multiple beam vibrating transducer. In this system, an amplified voltage at the resonant frequency of a master beam is applied to a secondary beam, allowing it to vibrate at the same frequency and amplitude. This innovation reduces energy losses to the adjacent mounting structure, resulting in a higher transducer quality factor. Consequently, frequency shifts in the resonant frequency can be measured effectively.
Another significant patent is for "Matched Pairs of Force Transducers." This invention features a matched pair of vibrating beam force transducers designed for instruments like accelerometers. It enhances linearity and common mode tracking while minimizing the risk of lock-in or cross-talk between the transducers. The arrangement allows one frequency to increase while the other decreases for a given acceleration, improving the overall performance of the accelerometer.
