Abstract: A wireless power system may use a wireless power transmitting device to transmit wireless power to a wireless power receiving device. The wireless power transmitting device may have microwave antennas that extend along an axis in a staggered arrangement. In the staggered arrangement, the microwave antennas are positioned on alternating sides of the axis. Each microwave antenna is elongated along a dimension that is perpendicular to the axis. Multiple antennas may overlap a wireless power receiving antenna in the wireless power receiving device. Control circuitry may use oscillator and amplifier circuitry to provide antennas that have been overlapped by the wireless power receiving antenna with drive signals. The drive signals may be adjusted based on feedback from the wireless power receiving device to enhance power transmission efficiency. The system may have a wireless power transmitting device with inductive wireless power transmitting coils.

Abstract: A mobile charging device may be used to move a battery or a power cord to a target device. The target device may be a vehicle or other equipment with a battery. Power from the power cord or battery in the charging device may be used to provide power to the target device to recharge the battery in the target device. The charging device may couple a power cord to the target device, may couple a connector in the charging device to the target device, or may use a wireless power transfer element such as a coil antenna to transfer power wirelessly to the target device. Sensors may be used to facilitate alignment between the charging device and target device. Sensors may also be used to dynamically detect and avoid foreign objects in the path of the charging device.

Abstract: Wireless power may be transferred using wireless power elements such as coil antennas for inductive wireless power transfer technology or patch antennas for capacitive wireless power transfer technology. These antennas in source equipment may couple in a near-field region to antennas implemented in target equipment. Wireless power may also be transferred from the source equipment to the target equipment using radiating antennas in their far-field regions. Wireless power transfer may be optimized by performing channel estimation operations. Foreign objects can be detected and located using sensors or by analyzing the quality of wireless channels. Optimum power transfer settings may be used to maximize wireless power transfer to a set of the antennas in the target equipment while minimizing power transfer to the foreign object.

Abstract: Electronic devices may include unshielded connectors that convey radio-frequency signals with external devices. A first electronic device may include transmitter circuitry that transmits radio-frequency signals to phase shifting circuitry. The phase shifting circuitry may pass the radio-frequency signals to a first conductive contact of a connector on the first device, may generate modified signals by applying a phase shift of approximately 180 degrees to the radio-frequency signals, and may provide the modified signals to a second conductive contact on the connector. To mitigate undesirable resonance and radiation at the connector, the connector may concurrently convey the radio-frequency signals and the modified signals to an external device over the first and second contacts while mating contacts on a connector of the external electronic device are in electrical contact with the first and second conductive contacts.

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: 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.

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.
