Abstract: Disclosed herein are microphone arrays for directional reception, along with related system, devices, and techniques. For example, a four-microphone array for directional signal reception may include first, second, and third microphones arranged such that projections of the first, second, and third microphones in a plane provide corners of a triangle in the plane. In some embodiments, a fourth microphone may be arranged such that a projection of the fourth microphone in the plane is disposed in an interior of the triangle. In other embodiments, the fourth microphone may be arranged such that the projection of the fourth microphone in the plane is disposed outside the interior of the triangle, and a distance between the first microphone and the second microphone is different from a distance between the first microphone and the third microphone.

Abstract: Disclosed herein are two-wire communication systems and applications thereof. In some embodiments, a slave node transceiver for low latency communication may include upstream transceiver circuitry to receive a first signal transmitted over a two-wire bus from an upstream device and to provide a second signal over the two-wire bus to the upstream device; downstream transceiver circuitry to provide a third signal downstream over the two-wire bus toward a downstream device and to receive a fourth signal over the two-wire bus from the downstream device; and clock circuitry to generate a clock signal at the slave node transceiver based on a preamble of a synchronization control frame in the first signal, wherein timing of the receipt and provision of signals over the two-wire bus by the node transceiver is based on the clock signal.

Abstract: Disclosed herein are systems and techniques for peripheral device diagnostics and control over a two-wire communication bus. For example, in some embodiments, a slave device may include circuitry to receive a synchronization control frame from an upstream device, receive audio data from the upstream device subsequent to receipt of the synchronization control frame, provide a synchronization response frame toward the upstream device, and provide first data representative of an operational characteristic of an audio device coupled to the slave device subsequent to provision of the synchronization response frame; circuitry to derive timing information from the synchronization control frame; and circuitry to provide the audio data to the audio device, and receive, from a sensor coupled to the slave device, second data representative of the operational characteristic of the audio device.
