  • Patent number: 11644929
    Abstract: Provided are a capacitance detecting circuit, a touch control chip, a touch detection apparatus and an electronic device. The capacitance detecting circuit, by configuring a first input side of an operational amplifier as a preset voltage, and utilizing the same characteristics of voltages at two input sides of the operational amplifier, enables that an output voltage in a touch sensor is configured as a preset voltage by a second input side of the operational amplifier, and by changing a position of a drive of a coding voltage, mutual-capacitance and self-capacitance detection can be realized with the same circuit. After replicating a single-channel current signal output by the operational amplifier into a multi-channel current signal, a current subtracting circuit is used to determine a differential signal of current signals output by two adjacent channels, and the differential signal is converted into a voltage through a charge amplifying circuit.

  • Patent number: 11450336
    Abstract: A system and method are described for automatic acoustic feedback cancellation in real time. In some implementations, the system may receive audio data describing an audio signal, which the system may use to determine a set of frames of the audio signal. Spectral analysis may be performed on the one or more frames of the audio to detect spectral patterns of two or more frames indicative of acoustic feedback. An additional delay identification test may be performed to identify a consistent delay indicative of acoustic feedback. In some implementations, a state machine is advanced based in part on accumulated delay votes. Decisions can be made to mute the acoustic feedback and cease the muting operation when silence is detected.
