Title: Donny F Rojo: Innovator in Accelerometer Technology
Introduction
Donny F Rojo is a notable inventor based in Redmond, WA (US). He has made significant contributions to the field of microelectromechanical systems (MEMS) accelerometers. With a total of 3 patents to his name, Rojo continues to push the boundaries of technology in his area of expertise.
Latest Patents
Rojo's latest patents include innovative designs that enhance the functionality of accelerometers. One of his key inventions is the "Extended-range closed-loop accelerometer." This device features extended operational capabilities beyond a closed-loop saturation. The invention combines the closed-loop feedback signal and the measured proof-mass position into a hybrid acceleration measurement. This effectively provides an operating range equal to the traditional closed-loop operating range plus the sensor's mechanical open-loop range.
Another significant patent is for "Systems and methods for vibration rectification error reduction in closed-loop accelerometer systems." This invention focuses on controlling a closed-loop accelerometer system. It includes an accelerometer with a driver that responds in a nonlinear manner and a rebalancing controller in signal communication with the driver. The rebalancing controller features a proportional-integral-derivative (PID) control portion with at least one variable gain component. The method involves sensing the movement of a proof mass, determining a static g field based on the sensed movement, and rebalancing the proof mass using the PID controller.
