Abstract: A device is disclosed for crankshaft-synchronous detection of a periodically changing variable of an internal combustion engine, for example the load, which is measured by a sensor whose output signal which is preprocessed or filtered in a suitable fashion is sensed with a selectable timing pattern. The start of sampling is resynchronized for each segment, the signal of a CA sensor being used for synchronization, the said CA sensor sensing a disc connected to the crankshaft and outputting one signal edge per segment. The combination for crankshaft-synchronous sampling with constant timing with respect to the segment permits the use of different load detection sensors with improved accuracy in comparison with previously used methods. The average value of the load for each segment can be determined from the sampled measured values and the quantity of air inducted per power cycle can also be determined.

During operation of the position sensor, the rotor is free from direct contact with either the supporting arms or any other stationary part of the position sensor. Only the contactors engage the stationary components. This design eliminates the need for bearings and return springs prevalent in the prior art.

Abstract: A non-destructive method and apparatus for determining the structural integrity of materials by combining laser vibrometry with damping analysis techniques to determine the damping loss factor of a material. The method comprises the steps of vibrating the area being tested over a known frequency range and measuring vibrational force and velocity as a function of time over the known frequency range.
