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: An electronic device may include an inverter. The inverter may convert direct current (DC) power to alternating current (AC) power. The inverter may use a clock signal at a given frequency to output corresponding alternating current signals at the given frequency. The inverter may receive a dithered clock signal that is frequency dithered using a modulating signal. The dithered clock signal may have at least three different frequency levels during a repeated cycle of the modulating signal. The at least three different frequency levels may include a fundamental frequency, a first frequency that is lower than the fundamental frequency, and a second frequency that is higher than the fundamental frequency. The dithered clock signal may be, during the repeated cycle of the modulating signal, at the fundamental frequency for fewer total periods than at the first frequency and for fewer total periods than at the second frequency.

Abstract: 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.

Abstract: 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.

Abstract: During operation, a first radar transmitter in an electronic device may provide, via a switch, a first set of electrical signals (such as pulses) during a first time interval to a transmission path, which may result in transmitting of the first wireless signals by an antenna. Then, a second radar transmitter may provide, via the switch, a second set of electrical signals (such as pulses) during a second time interval to the transmission path, which may result in transmitting of the second wireless signals by the antenna. Moreover, N radar receivers in the electronic device may receive first wireless-return signals corresponding to the first set of wireless signals and second wireless-return signals corresponding to the second set of wireless signals. These wireless-return signals may be combined to create a virtual array MIMO radar having an antenna aperture size of 2N.
