Title: The Innovations of Donald R. Cargille
Introduction
Donald R. Cargille is a notable inventor based in Culver City, CA, with a remarkable portfolio of 13 patents. His contributions to the field of technology have led to significant advancements, particularly in the areas of filter circuits and micro-gyroscopes.
Latest Patents
Among his latest inventions is the "Digitally Tuned Analog Notch Filter Circuit." This innovative circuit includes a first stage that sums a filter input signal with a filter output signal to create a summation signal. The second stage features a first tee network and a second tee network, where the first tee network low-pass filters the input signal, and the second tee network high-pass filters the summation signal. A first multiplying digital-to-analog converter is connected to both networks, allowing for gain adjustments to fine-tune the notch filter frequency.
Another significant invention is the "Microgyroscope with Closed Loop Output." This micro-gyroscope operates with closed-loop functionality, utilizing a control voltage that is demodulated by the output signal of the sense electrodes. This design provides Coriolis torque rebalance, preventing displacement on the output axis. The invention allows for wide-band, closed-loop operation and enables precise tuning to high Q sense axis resonance.
