    Abstract: The disclosure relates and extends to a light source having a strobing or pulsing sequence suitable for use with a CMOS sensor that does not require, have, or use a global shutter. Instead, the CMOS sensor synchronizes the strobing input with the blanking portion of the sensor readout pattern and disables the strobing during sensor readout, or when the strobing would otherwise leave artifacts in the image. The CMOS sensor freezes its readout during the strobing.

    Abstract: A wireless stethoscope is described, having wireless sensors that are enclosed in disposable pads so that the same pads are not used on more than one patient, preventing cross-infection of patients associated with conventional stethoscopes. The present wireless stethoscope also detects pulmonary sounds and cardiac sounds, allowing the user to monitor one or the other without interference. Also described is a method for diagnosing a pulmonary condition using the wireless stethoscope.

  • Patent number: 8979771
    Abstract: Acoustic impulses from a muscle are converted into an electrical signal with a transducer such as a piezo film microphone, and analog or digital signal processing circuitry determines the density of self-similar spectral components of the signal and generating an output signal representative of the contractile force of the muscle based upon the density of the self-similar spectral components. The circuitry is used to determine self-similar spectral components of the signal and the density of those components, and the density is used to provide an output signal filtering. Different embodiments use combinations of filtering, Fourier analysis and correlation or auto-correlation. The self-similar spectral components may be pre-determined or determined through signal processing. The output signal may be used to calculate muscle contractile force, fatigue or other muscle conditions.
