  • Motor bearing damage detection via wavelet analysis of the starting current transient
    Patent number: 6727725
    Abstract: An apparatus and method for detecting motor bearing defects obtains motor current transient data during motor start-up, analyzes the motor current transient data via discrete wavelet transform, and compares the wavelet sub-bands to a baseline signature of a bearing-defect-free motor to detect bearing defects.

  • Time reference compensation for improved metering accuracy
    Patent number: 6714881
    Abstract: A method for time reference compensation in a power metering system, the method comprising monitoring a time-dependent characteristic of incoming AC power over a predetermined local time interval, comparing the monitored characteristic over the predetermined local time interval with the expected value of the characteristic based upon the nominal frequency of the AC power, and calculating a correction to one or more of local real-time and time-based measurements of the power metering system, based on the comparing.

  • Motor bearing damage detection via wavelet analysis of the starting current transient
    Publication number: 20020186039
    Abstract: A method for detecting motor bearing defects includes obtaining motor current transient data during motor start-up, and analyzing the motor current transient data to detect changes in RMS levels due to bearing defect-induced resonance.

  • Vehicle interior deicing/defogging system
    Patent number: 4501390
    Abstract: In an arctic vehicle having a heater for the passenger compartment, it is oposed to add an external heat exchanger to remove (condense) moisture from air flowing through the heater. The relatively dry air discharged from the heater into the passenger compartment is less likely to produce fogging or icing on interior surfaces of the vehicle windows. Eliminating or minimizing the fogging-icing condition improves passenger visibility. The invention has special application to military vehicles.
