  • Publication number: 20240040309
    Abstract: Various techniques pertaining to non-coherent noise reduction for audio enhancement on a multi-microphone mobile device are proposed. A processor receives a plurality of signals from a plurality of audio sensors corresponding to a plurality of channels responsive to sensing by the plurality of audio sensors. The processor then performs a non-coherent noise reduction on one or more signals of the plurality of signals to suppress one or more non-coherent noises in each of the one or more signals based on a respective signal-to-noise ratio (SNR) associated with each of the one or more signals. The processor further combines the plurality of signals subsequent the noise reduction to generate an output signal.

  • Patent number: 11530455
    Abstract: Methods for human identification using polymorphisms in the Penta E short tandem repeat locus are significant in preventing allelic drop out. An exemplary method encompasses (a) contacting a first primer to a nucleic acid sample to be analyzed, (b) contacting a second primer to the nucleic acid sample, and (c) subjecting the nucleic acid sample, the first primer, and the second primer to an amplification reaction, and thereby forming an amplification product. The first primer, the second primer, or both the first and second primers can be labeled with a non-nucleic-acid label. Additionally, or alternatively, the amplification product can include an adenosine at position 14 from the 5? end of SEQ ID NO:1, a thymidine at position 21 from the 5? end of SEQ ID NO:2, or both an adenine at position 14 and a thymidine at position 21 from the 5? end of SEQ ID NO:3.

  • Patent number: 10651656
    Abstract: A control system and method include a control strategy and a UDE (Uncertainty and Disturbance Estimator)-based controller incorporated into the control strategy to achieve proportional load sharing for parallel-operated inverters. The UDE-based controller regulates the reactive power against the output generated by a reactive power reference unit according to the load voltage to generate the amplitude of the control voltage. The conventional droop method regulates real power to generate the phase of the control voltage. As a result, the model uncertainties (e.g., parameter drifts and uncertain output impedance), and system disturbances (e.g., fluctuating DC-link voltage and load change) can be estimated and compensated for accurate load sharing.
