Abstract: An electronic device that selectively performs a predefined action is described. The predefined action can be any action performed by the electronic device, such as changing the power state of the electronic device or a component, change the state of a display, initiating a process, ending a process, etc. During operation, the electronic device may transmit a wireless signal. Then, the electronic device may receive a wireless-return signal associated with an object, which can indicate a time-of-flight of the wireless signal between the electronic device and the object. Moreover, the electronic device may determine a range between the electronic device and the object based at least in part on the wireless-return signal. When the range between the electronic device and the object is less than a threshold value, the electronic device may determine: whether the range between the electronic device and the object is varying and/or whether to perform the predefined action.

Abstract: Wireless power transmitting equipment may transmit wireless power signals to wireless power receiving equipment. The wireless power transmitting equipment may have a wireless power transmitter coupled to a wireless power transmitting coil. The wireless power receiving equipment may have a wireless power receiving coil coupled to wireless power receiving circuitry such as a rectifier. Foreign object detection coil arrays may be formed from arrays of metal traces on printed circuit substrates that overlap the wireless power transfer coils. Control circuitry in the transmitting equipment and the receiving equipment may monitor signals from foreign object detection circuitry that is coupled to the coil arrays. The foreign object detection circuitry may produce in-phase and quadrature signals that are indicative of whether a foreign object is overlapping a foreign object detection coil array.

Abstract: An electronic device that performs radar measurements is described. This electronic device includes independent, co-located radar transceivers, and the independent radar transceivers are not synchronized with each other. Moreover, the radar transceivers may have different fields of view that partially overlap. During operation, the radar transceivers transmit radar signals and perform the radar measurements. Then, based at least in part on the radar measurements, the electronic device determines a location of an object in an environment around the electronic device. For example, the location may include an angular position that is determined from the amplitudes of the radar measurements performed using at least a subset of the radar transceivers. Furthermore, the object may be an individual, and the electronic device may identify the individual based at least in part on the radar measurements. Note that the radar measurements performed by a given radar transceiver do not provide angular information.

Abstract: A wireless power system uses a wireless power transmitting device to transmit wireless power to wireless power receiving devices. The wireless power transmitting device has wireless power transmitting coils that extend under a wireless charging surface. Non-power-transmitting coils and magnetic sensors may be included in the wireless power transmitting device. During wireless power transfer operations, control circuitry in the wireless power transmitting device adjusts drive signals applied to the coils to reduce ambient magnetic fields. The drive signal adjustments are made based on device type information and other information on the wireless power receiving devices and/or magnetic sensor readings from the magnetic sensors. In-phase or out-of-phase drive signals are applied to minimize ambient fields depending on device type.
