Abstract: Systems and methods include a plurality of audio input components configured to generate a plurality of audio input signals, and a logic device configured to receive the plurality of audio input signals, determine whether the plurality of audio signals comprise target audio associated with an audio source, estimate a relative location of the audio source with respect to the plurality of audio input components based on the plurality of audio signals and a determination of whether the plurality of audio signals comprise the target audio, and process the plurality of audio signals to generate an audio output signal by enhancing the target audio based on the estimated relative location. The logic device is further configured to use relative transfer-based covariance to construct directional covariance matrix aligned across frequency bands and find a direction that minimizes beam power subject to distortionless criteria.

Abstract: An operational amplifier includes a first transistor, a second transistor, a third transistor, a first constant current source, an output state, a first switch, and a second switch. The first transistor has a first gate configured to receive an output voltage from an output node. The second transistor has a second gate. The third transistor has a third gate configured to receive an input voltage. The first constant current source is coupled to sources of the first transistor, the second transistor, and the third transistor. The output stage is configured to drive the output voltage on the output node based on a first current through the first transistor, a second current through the second transistor, and a third current through the third transistor. The first switch is coupled between the second gate of the second transistor and the third gate of the third transistor; and the second switch is coupled between the output node and the second gate of the second transistor.

Abstract: A system and method for capacitive sensing comprises driving a first sensor electrode of a plurality of sensor electrodes with a first sensing signal to acquire a first resulting signal with the first sensor electrode during a period and driving a second sensor electrode of the plurality of sensor electrodes with the first sensing signal to acquire a second resulting signal with the second sensor electrode during the period. Further, a third sensor electrode of the plurality of sensor electrodes is driven with a reference signal during the period. Rotational information for an input object is determined at least partially based on the first resulting signal and the second resulting signal.

Abstract: A method and system for securing in-vehicle ethernet links are disclosed. According to one embodiment, a method comprises receiving from an authenticator, via an insecure channel, a public key of the authenticator, a random number, and a challenge. A private key of the peer that was supplied to the peer is accessed from local storage at the peer. A state machine computes a session key for the peer, based on the random number, the public key of the authenticator, and the private key of the peer. The state machine computes a peer response to the challenge using the session key for the peer and a symmetric cipher function.
