Abstract: In one embodiment, a power supply comprises: a conversion circuit that outputs an output voltage at a first end of a cable; a remote voltage sensor measures a load delivered voltage from a second end of the cable; a control logic, wherein the power conversion circuit regulates the output voltage based on a signal from the control logic; a current sensor that measures current flow through the cable; and a resistance measurement circuit that computes a resistance of the cable as a function of the load delivered voltage, the current flow and the output voltage.

Abstract: In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. The processing circuitry receives coded information of a current block in a current picture from a coded video bitstream. The coded information includes a syntax element with a value indicative of a merge with motion vector difference (MMVD) mode being applied on the current block. The processing circuitry determines, in response to a motion vector predictor of a merge candidate being a bi-predictor, whether the merge candidate for the current block satisfies a requirement for applying a bi-prediction motion refinement. The processing circuitry can constrain the merge candidate for use in the MMVD mode when the merge candidate for the current block satisfies the requirement. Then, the processing circuitry reconstructs the current block in the MMVD mode with the merge candidate being constrained for use in the MMVD mode.

Abstract: Hearing instruments, such as hearing aids, may improve a quality of presented audio through the use of a binaural application, such as beamforming. The binaural application may require communication between the hearing instruments so that audio from a left hearing instrument may be combined with audio from a right hearing instrument. The combining at a hearing instrument can require synchronizing audio sampled locally with sampled audio received from wireless communication. This synchronization may cause a noticeable delay of an output of the binaural application if the latency of the wireless communication is not low (e.g., a few samples of delay). Presented herein is a low-latency communication protocol that communicates packets on a sample-by-sample basis and that compensates for delays caused by overhead protocol data transmitted with the audio data.
