Latest Patents

Yumi Yoshida holds a patent for a "Method and apparatus reducing output noise in a digitally rebalanced accelerometer." This invention involves a closed-loop accelerometer that incorporates apparatus within an associated digital rebalance loop to minimize low-frequency moding noise in the accelerometer output. In one embodiment, the digitized corrective signal is applied to a moving average filter. In another embodiment, the corrective signal is modulated with a random function. Additionally, in a third embodiment, the digitized corrective signal is both randomized and applied to a moving average filter. Each of these embodiments significantly reduces the periodic moding noise that results from the analog-to-digital conversion within the rebalance loop, improving upon prior art systems. Yumi has 1 patent to her name.
