  • Low energy system for sensor data collection and measurement data sample collection method
    Patent number: 10571989
    Abstract: A data collection system includes one or more input sensing devices and a data collection device. The data collection device includes data collection circuitry that is continuously activated to capture measurement data samples from the one or more input sensing devices and locally store the measurement data samples. The data collection device also includes a digital processor that is coupled to the data collection circuitry and is activated to locally perform a sample analysis of the measurement data samples, wherein the sample analysis is a regular analysis of routine measurement data samples when the measurement data samples are without a triggering event, and wherein the sample analysis is an event analysis when the measurement data samples include a triggering event. A data collection integrated circuit and a measurement data sample collection method are also included.

  • Real-time microphone array with robust beamformer and postfilter for speech enhancement and method of operation thereof
    Patent number: 9538285
    Abstract: A microphone array processing system and method carried out in the system. In one embodiment, the system includes: (1) a beamformer configured to perform adaptive beamforming on gain-compensated signals received from a plurality of microphones, the adaptive beamforming including dynamic range compression and diagonal loading of a sample correlation matrix based on order statistics and (2) a postfilter configured to receive an output of the beamformer and reduce noise components remaining from the beamforming.
