The medium can be coupled to the muscular-skeletal system or be part of the muscular-skeletal system. A sensor comprises one or more transducers, an edge detect circuit or a reflecting surface. A parameter is applied to the medium and the parameter affects the medium. A transducer receives an energy wave that has traversed the medium and generates an energy wave signal. The edge-detect receiver receives the energy wave signal signal from the transducer and generates a pulse upon sensing a leading edge corresponding to a wave front of the energy wave. The edge-detect receiver comprises a preamplifier, a differentiator, a digital pulse circuit, and a deblank circuit. The transit time, phase, or frequency is measured of the propagating energy waves and correlated to the parameter being measured.

  • Publication number: 20140283607
    Abstract: The adjustable voltage regulator under control of a microcontroller applies controlled amplitude voltage in the range of 5 to 9 VDC to the sensor transmitter to adjust the output amplitude of the transmitter. The adjustable amplitude transmitter allows an occupancy sensor to have its total output energy adjusted to reduce environmental noise-induced false triggering and to conform to the area to be covered. Lowering the total ultrasonic energy in the monitored space lowers the sensitivity of the receiver to inappropriate activations. Lowering the input power to the transmitter also lowers the total internal system noise and provides an improved signal to noise ratio in the receiver.

  • Patent number: 8668646
    Abstract: A sensing assemblage (1) for capturing a transit time, phase, or frequency of energy waves propagating through a medium is disclosed to measure a parameter of the muscular-skeletal system. The sensing assemblage (1) comprises a transducer (2) and a waveguide (3). The transducer (2) is coupled to the waveguide (3) at a first location. A second transducer (11) can be coupled to the waveguide (3) at a second location. An interface material that is transmissive to acoustic energy waves can be placed between transducers (402, 404) and a waveguide (414) to improve transfer. The interface material (408, 410) can affix the transducers (402, 404) to the waveguide (414). Alternatively, a reflecting feature (5) can be placed at a second location of the waveguide (3) to reflect acoustic waves back to the transducer (2) where transducer (2) emits energy waves into the medium and detects propagated energy waves.

  • Patent number: 8661903
    Abstract: A machine has at least two wheels (at least one of them driven) arranged on a base body and connected with a revolving belt. A transmitter and a receiver are arranged on the base body. The transmitter transmits contactless to the belt a transmitted signal having an oscillation frequency, with the receiver from the belt a reflected signal in response to the transmitted signal. An evaluation device connected to the receiver checks if the reflected signal received by the receiver satisfies an acquisition condition indicating that a speed of the belt is in a predetermined speed range. The evaluation device determines, if the acquisition condition is satisfied, a frequency spectrum which is based of the oscillation frequency and the reflected signal in the predetermined speed range and indicative of a mechanical oscillation characteristic of the belt, and generates a control signal based on the evaluated frequency spectrum.
