    摘要： A sensing device comprised of a sensing circuit which changes its operating characteristics when an object comes near it. The sensing circuit produces a change in output voltage proportional to the change in relative distance between the sensing circuit and an object. The actual output voltage is a function of both target distance and control circuit input voltage. The control circuit includes a comparator for comparing the steady state output voltage to a reference voltage and adjustment system for adjusting the input voltage to change the steady state output voltage such that the steady state output voltage approximately equals the reference voltage. The control circuit reacts only to reductions in the steady state output voltage, indicative of mechanical wear, and not to increases in output voltage, indicative of currency thickness measurement.

    摘要： An apparatus for sensing a target characteristic, such as relative distance between the apparatus and target, target thickness, target material, or lateral position between the apparatus and the target, includes a coil for directing an electro-magnetic field at the target. A voltage controlled oscillator energizes the coil at a resonant frequency which is functionally related to the target characteristic. The coil has an effective impedance value at resonance functionally related to the target characteristic. A frequency monitor measures the resonant frequency. An impedance monitor determines the impedance value when the drive frequency is at the resonant value. A PROM or controller determines the target characteristic in response to the measured resonant frequency and the determined impedance value. The PROM or controller provides a signal responsive to the determined target characteristic.

    摘要： A target has leading and trailing edges which are boundaries between a retroreflector and a non-retroreflector. The target is used in target determining apparatus for distance, width, azimuth, gauging, profiling, object detection, and particular target identification. A laser light source scans along a scanning path across the target. The retroreflector reflects light back toward the scanning means where it is received in a photoreceptor to determine the angles of the target edges. The distance to the target and the width are inversely proportional to the length of time that the light beam scans across the target. The laser light also scans across a reference point and the length of time between this reference point and the reflection from the target is directly proportional to the azimuthal position of the target relative to the reference. Further, the target may include a plurality of reflective and non-reflective strips transverse to the scanning path to establish binary indicia on the target. This results in a series of pulses from the photoreceptor as the beam scans the width of the target. This information is then decoded to determine the binary indicia and hence identify that particular target. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

    摘要： A detector for a deposit accepting apparatus of an automated banking machine or for another sheeting handling system includes an ultrasonic transmitter driven by a driving signal operative to cause the ultrasonic transmitter to transmit an ultrasonic sound signal through a sheet pathway of the detector. The detector also includes an ultrasonic receiver operative to generate a receiver signal responsive to the ultrasonic sound signal. The detector further includes first and second correlation filters. The first and second correlation filters are operative to generate first and second outputs responsive to the receiver signal. At least one processor is operative responsive to the first and second outputs of the correlation filters to determine information associated with changes in phase of the ultrasonic sound signal and to distinguish between single and multiple sheets in the pathway responsive to the information associated with changes in phase.
