摘要： A quantitative process for monitoring female fertility cycle wherein the process involves directing a laser beam, preferably generated by a diode laser, onto an area of a slide containing an air-dried sample of a female body fluid. The diffraction pattern resulting from the sample is detected by a two-dimensional photo diode array and analyzed by a microprocessor. If a ferning pattern exists, such pattern will generate a characteristic structure in the diffraction pattern which is then detected by the photo diode array. If no ferning occurs, the corresponding diffraction pattern will be structureless. The microprocessor is programmed with an algorithm to produce a quantitative index of ferning indicating quantitatively the ferning level. Preferably, a plurality of spots on the sample are measured to determine the ferning level at each spot, and the microprocessor then makes a final determination as to final ferning level on the basis of the test results of all of the spots. This significantly increases the reliability of the final test result, since a defect at one test spot or anomaly of one test result will not be fatal to the final result.

摘要： A motor control system for controlling operation of an electric motor associated with a motor-operated vent in a vehicle. The system monitors and stores data relating to the operating current and detects occurrences of abnormal loads applied to the vent by determining whether the monitored operating current exceeds one of several predetermined thresholds. The predetermined thresholds are dynamically modified in accordance with monitored condition variations of the operating current. The dynamically modified thresholds are initially based on either a value associated with the stall current of the vent motor or the start spike current of the vent motor. In addition, an embodiment is provided for monitoring and storing data relating to ripple current waves associated with the operating current, so that occurrences of abnormal loads may be detected by determining whether the frequency of the monitored ripple current waves is less than a predetermined value.
