摘要： A wireless power system has a wireless power transmitting device and a wireless power receiving device. A clock signal may be provided to inverter circuitry in wireless power transmitting circuitry at a power transmission frequency. The clock signal may cause transistors in the inverter circuitry to turn on and off to create AC current signals through the wireless power transmitting coil. The clock signal may be processed to mitigate electromagnetic interference in the system.

摘要： An electronic device may utilize various methods or systems to determine whether the electronic device is indoors or outdoors. The electronic device transmits wireless signals (e.g., radio detection and ranging (RADAR) signals). The electronic device receives reflections of the wireless signals. Using these received reflections of the wireless signals, the electronic device determines whether a power amplitude of the reflections is greater than or equal to a threshold value. In response to a determination that the power amplitude is not greater than or equal to the threshold value, the electronic device operates in an outdoor mode or an indoor mode.

摘要： An electronic device includes M separate radar transmitters and N separate radar receivers co-located in the electronic device, where the M radar transmitters and the N radar receivers are arranged in a circular architecture providing 360° coverage in a horizontal plane. Moreover, the N radar receivers are synchronized, e.g., using a clock signal. During operation, subsets of the M radar transmitters sequentially transmit radar signals and, when a given subset of the M radar transmitters is transmitting, at least a subset of the N radar receivers performs radar measurements. Furthermore, at least the subset of the N radar receivers can perform the radar measurements using circular beamforming. 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, where the location includes a range and an angular position.
