摘要： Method and apparatus for controlling the power consumption of a wireless device are provided. A wireless device may include a configurable radio frequency (RF) front-end that may be configured to use fewer hardware stages and/or processing steps to reduce power consumption based at least in part on a signal quality, detected interference, or system information associated with a received RF signal. In some implementations, the configurable RF front-end may be configured to consume less power while receiving strong RF signals and configured to consume more power while receiving weak RF signals.

摘要： Method and apparatus for wirelessly transmitting and receiving power between devices are provided. A first device may convert power into RF energy and transmit the RF energy to a second device. In some implementations, the first device may steer the RF energy using beamforming techniques to the second device. The second device may receive and convert the RF energy into power for the second device. In some implementations, the second device may be powered solely or in part by power transmitted by the first device. In some implementations, the first device may include two or more RF energy harvesters and a power combiner. The power combiner may combine power from the two or more RF energy harvesters to power the second device and/or charge a battery.

摘要： Method and apparatus for generating and receiving a paging signal are provided. The paging signal may be received by a wireless device in a low-power state. The paging signal may include a target identification (ID) that may be associated with the wireless device. If the target ID is associated with the wireless device, the wireless device may leave the low-power state, enter an active power state and communicate with other wireless devices. The wireless device may include power harvesting circuitry to convert RF energy from the paging signal into power to operate a portion of the wireless device.

摘要： A wearable wireless device includes a wireless transceiver coupled to a first antenna, an energy harvester coupled to a second antenna, and a supercapacitor coupled to the energy harvester. The wireless transceiver may be configured to receive a first wireless signal from a paired wireless communication device via the first antenna. The energy harvester may be configured to convert radio-frequency (RF) energy received by the second antenna into a charge. In some instances, the energy harvester may be further configured to charge the supercapacitor in response to a presence of the RF energy. The supercapacitor may be configured to store the charge converted by the energy harvester and provide power to the wireless transceiver. In some instances, the supercapacitor may be further configured to power one or more electronic components of the wearable wireless device with the stored charge.
