  • Highly-reliable micro-electromechanical system temperature sensor
    Patent number: 9039280
    Abstract: A micro-electromechanical system-type (MEMS) sensor arrangement for wirelessly measuring temperatures is disclosed. The MEMS sensor arrangement includes a multimorph sensor, a sensor coil coupled to the multimorph sensor, and a readout coil configured to be magnetically coupled to the sensor coil to i) energize the sensor coil, and ii) provide a readout of the natural frequency of the multimorph sensor, the sensor coil and the readout coil.

  • Damage detection using laser vibrometry
    Patent number: 8656779
    Abstract: Methods and apparatus for exciting a structure and determining its structural integrity. In particular, methods of nonlinear analysis are used to compare first and second response datasets, each dataset resulting from a different excitation amplitude that the other dataset.

  • METHODS AND APPARATUS FOR DIAGNOSING FAULTS OF A VEHICLE
    Publication number: 20110257900
    Abstract: A rubber cleat is instrumented with two triaxial accelerometers to measure the multi-directional response of the cleat due to the forces within the tire footprint of a ground vehicle. The cleat data is used to detect faults in the front and rear suspension in addition to the wheel tire despite variability in the data. This offboard diagnostic technique is proposed to enable condition-based maintenance.

  • Vibration isolation mount
    Patent number: 6302385
    Abstract: A vibration isolation mount particularly usefull for a hydraulic automotive vehicle braking system includes a shear mount, a rate washer, and a bolt and nut for clamping the shear mount and rate washer together and to the vibrating member. The shear mount is shaped to engage an opening in a support structure, such as a mounting bracket, and thereby connect the vibrating member to the support. In automotive applications, the mount reduces the amount of noise and vibration that is transmitted to the passenger compartment over prior art mounting systems while restricting travel of the accumulator plate with respect to the vehicle bracket within predetermined limits.
