An AlN thin film on an Al2O3 substrate is used as a piezoelectric layer in the sensor system and produces the necessary energy for its operation. Sputtered molybdenum and aluminium layers are used as lower and upper sensing electrodes,

The upcoming GLAST mission will detect several hundred radio quiet Gamma-Ray pulsars. We present a fast method for finding the spin parameters of Gamma-Ray pulsars in a blind search. The sensitivity of our new method was determined with a simple pulsar simulation and simulated GLAST data. We also demonstrate the benefits of the new method on EGRET data.

For bidirectional switches where the current flow is controllable separately for both directions this paper proposes new commutation strategies. Based on the measurement of the current direction and the signs of the line to line input voltages commutation in
