Abstract: A method and system for early detection of incipient faults in an electric motor are disclosed. First, current and voltage values for one or more phases of the electric motor are measured during motor operations. A set of current predictions is then determined via a neural network-based current predictor based on the measured voltage values and an estimate of motor speed values of the electric motor. Next, a set of residuals is generated by combining the set of current predictions with the measured current values. A set of fault indicators is subsequently computed from the set of residuals and the measured current values. Finally, a determination is made as to whether or not there is an incipient electrical, mechanical, and/or electromechanical fault occurring based on the comparison result of the set of fault indicators and a set of predetermined baseline values.

Abstract: The present invention is directed to method and apparatus for detecting base station (BS) transceivers malfunctions in a cellular telecommunications system. A Transceiver Malfunction Detector (TMD) receives and stores information related to the service performance of the BS transceivers and sorts the information on a per transceiver basis, for generating a service quality value for each transceiver. The TMD computes a service quality threshold value proportional to the average performance of the BS transceivers, and compares the service quality value of each monitored transceiver with the threshold, for determining the acceptability of the transceiver performance. The TMD also detects the cause of a malfunction in a transceiver, by assigning the frequencies used by an adequate transceiver to a transceiver suspected to be malfunctioning and by further monitoring the activity of the initially malfunctioning transceiver.

Abstract: A radar based sensor detection system comprises a microwave source operative to provide a continuous wave signal at an output. A pulse-former is coupled to the output of the source and is operative to provide at an output a variable length pulse that increases the transmitted energy of the radar system according to the range of object detection. A modulator is coupled to the output of the pulse-former for providing a modulated pulse signal. A transmit receive switch coupled to the output of the modulator is selectively operative between a first transmit position and a second receive position. A transmit channel coupled to the transmit receive switch transmits the pulse signal when the switch is operated in the transmit position. A receiving channel coupled to the transmit receive switch receives the modulator signal when the switch is operated in the receive position.
