Abstract: Attributes for point cloud compression may be predicted according to a space filling curve. An order for selecting points of a point cloud to be compressed in order to predict attributes of the points may be determined according to values of a space filling curve applied to spatial information for the points. A point of the point cloud may be selected according to the determined ordering. A prediction technique may be performed with respect to the selected point based on a set of neighboring points in the point cloud also selected according to the ordering. Predicted attribute values and correction values may be determined for the predicted values. The correction values may be encoded as part of a compressed version of the point cloud.

Abstract: A circuit and method for protecting from reverse current is disclosed. A reverse current protection circuit is coupled to a pass transistor of power circuitry (e.g., a power switch or voltage regulator), the pass transistor being coupled between first and second voltage nodes, the first voltage node being coupled to a power supply circuit. The reverse current protection circuit includes a sensing circuit that is configured to sense an amount of reverse current flowing through the pass transistor (from the second voltage node to the first voltage node). Responsive to the amount of reverse current exceeding a threshold value, the reverse current sensing circuit activates a shunt circuit, which redirects at least some of the reverse current to a reference node (e.g., ground).

Abstract: In an embodiment, a method includes receiving, by a processor of a mobile device, raw pedometer data from a pedometer included in or coupled to the mobile device. The processor receives raw GNSS data from a GNSS receiver included in or coupled to the mobile device. A first filter uses the raw pedometer data to estimate a step frequency of a user wearing or holding the mobile device. The processor determines a pace change from the estimated step frequency. Responsive to the pace change, the processor adapts a bandwidth of a second filter and estimates, by the second filter, an estimated pace or speed of the user.

Abstract: An interface circuit in an electronic device may provide rate feedback. During operation the interface circuit may transmit one or more packets or frames associated with a data stream that are intended for the recipient electronic device, where the data stream is associated with a video encoder. Then, the interface circuit may estimate a communication performance metric associated with at least the transmissions. For example, the estimated communication performance metric comprises an effective capacity associated with a wireless link between the electronic device and the recipient electronic device. Moreover, the effective capacity may be estimated based at least in part on an efficiency of the wireless link. Next, the interface circuit may provide the rate feedback intended for the video encoder based at least in part on the estimated communication performance metric. In some embodiments, when beamforming occurs, the rate feedback may be reset.

Abstract: Systems and processes for selectively processing and responding to a spoken user input are provided. In one example, audio input containing a spoken user input can be received at a user device. The spoken user input can be identified from the audio input by identifying start and end-points of the spoken user input. It can be determined whether or not the spoken user input was intended for a virtual assistant based on contextual information. The determination can be made using a rule-based system or a probabilistic system. If it is determined that the spoken user input was intended for the virtual assistant, the spoken user input can be processed and an appropriate response can be generated. If it is instead determined that the spoken user input was not intended for the virtual assistant, the spoken user input can be ignored and/or no response can be generated.
