  • Publication number: 20160225410
    Abstract: Embodiments are disclosed to create a highlight video clip of a first physical event and a second physical event from one or more video clips based on a sensor parameter value generated by a sensor. Upon a physical event occurring, one or more associated sensor parameter values may exceed one or more threshold sensor parameter values or match a stored motion signature associated with a type of motion. Physical events may be recorded from multiple vantage points. A processor of a device or system may generate a highlight video clip by selecting a first video time window and a second video time window from the one or more video clips such that the first video time window begins before and ends after a first event time and the second video time window begins before and ends after a second event time.

  • Patent number: 5287107
    Abstract: The present invention provides an optical isolation amplifier which generates a low-noise analog output signal linearly related to an analog input signal and which conveniently fits within a conventional 8-pin dual in-line package. The optical isolation amplifier package includes an input chip having a sigma-delta analog-to-digital (A/D) converter for converting an analog input signal to a digital signal. The sigma-delta converter is used to modulate an off-chip LED which optically transmits the signal to a photodetector on a separate output chip having an accurate optical recovery section for reproducing the transmitted signal. Also contained on the output chip is a digital-to-analog (D/A) converter for converting the digital signal to an analog output signal linearly related to the analog input signal.
