Abstract: 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.

Abstract: Each of a plurality of acoustic sensors (acoustically coupled to a structure for monitoring) is connected to a network bus system via a preamplifier for capturing, processing and reporting acoustic events in a structure, for example aircraft structures. Each of the preamplifiers processes the acoustic event signals received from the sensors when an acoustic emission resulting from an acoustic event (defect in a structure, impact on the structure etc), and passes digital processed signal data relating to the detected acoustic event to a Remote Data Concentrator over the network for collation. The collated data is then stored and/or further processed (at a later time or in near real-time) to determine the source and/or location of detected acoustic emissions in the structure.
