摘要： An active vibration absorber is provided for absorbing vibrations in a member (21). An inertial mass (22) is mounted on the member with a stiffness (24) between the member and the mass. A force actuator arrangement (23) applies a force between the inertial mass and the member. A damping arrangement provides for damping of a resonance of the active vibration absorber. A first sensor arrangement (29) provides at least one first signal indicative of at least one movement and/or stress related parameter for the member and a second sensor arrangement (25) provides for at least one second signal indicative of a reaction of the inertial mass. A control arrangement (30) is provided for controlling the force actuator arrangement using the at least one first signal and the at least one second signal.

摘要： The present invention generally relates to proximity sensor monitors and proximity monitor systems incorporating proximity sensor monitors. A proximity sensor monitor measures the impedance or other electrical characteristics of a proximity sensor component to determine the presence of a target. The proximity sensor monitor performs this measurement independently of a separate proximity sensor. The proximity sensor monitor is configured to compensate for differences between the measurement frequency of the proximity sensor monitor and the driving frequency of the proximity sensor.
