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. The apparatus comprises a shift lever to receive shift range selection manipulating force of a driver; a manual valve to control oil pressure of the automatic transmission; and a linkage unit for connecting the shift lever and the spool of the manual valve to enable the spool to identically form an interconnection state of ports according to pivot of the shift lever in ranges P and N. A method of separating the upper hull structure from the lower module includes disconnecting the lower module from the lower end of the upper hull structure, and then allowing the weight of the mooring line assemblies to sink the lower module. According to another embodiment, a system for pre-analyzing a digital signal for encoding at least one digital watermark using a digital filter is disclosed. The electrically conductive portion of the sound transducer constitutes a portion of the ground plane of the antenna. The increased helium ionization enables formation of helium ion beams having a high beam currents suitable for implantation.
