Latest Patents

One of Johnson's latest patents is the Temperature-compensated surface micromachined angular rate sensor. This advanced motion sensor features a micromachine sensing element and electrodes formed on a silicon chip. The design includes a sensing ring supported above a substrate, allowing for an axis of rotation that is normal to the substrate. The configuration of the sensing ring and electrode structures is such that it enables partial cancellation of the effects of differential thermal expansion, making the sensor's performance largely insensitive to temperature variations. Additionally, the sensor incorporates circuitry that creates and detects electrostatic forces, ensuring that temperature changes have a minimized impact on sensing performance.

Another significant patent is the Method and apparatus for detecting failure in vibrating sensors. This yaw sensor, designed for automotive controls, utilizes a microstructure vibrating ring that is excited by a driving circuit. The circuit includes an amplitude control loop that delivers voltage pulses at the resonant frequency of the ring. By comparing sensed vibration amplitudes to desired levels, the system can detect failures in vibration and replace the yaw output signal with ground potential when necessary.
