  • Patent number: 10665082
    Abstract: This application is directed to techniques and processes for notifying a user about power levels of electronic devices. For example, a first electronic device may receive data representing the power level of a second electronic device. The first electronic device may then determine that the power level is below a threshold power level. After the determination, the first electronic device may detect a user and/or a client device located within a threshold distance to the first electronic device and/or the second electronic device. The first electronic device may then send data to the second electronic device, wherein the data includes a command to emit light according to a pattern indicating that the power level is below the threshold power level. Additionally, the first electronic device may send a message to the client device, where the message indicates that the power level is below the threshold power level.

  • Patent number: 9948113
    Abstract: Systems (100) and methods (500, 600) for adaptively managing power for an Energy Harvesting System (“EHS”). The methods involve: measuring a light intensity level available in a surrounding environment; wirelessly communicating a first wireless signal from the EHS (100) to a remote device (700) for causing the light intensity level to be increased by remotely turning on a light source (106, 108) or opening a cover preventing light emitted from the light source from reaching the EHC, when the light intensity level is below a pre-specified level; using an Energy Harvesting Circuit (“EHC”) to recharge a rechargeable battery (310) when the light intensity level rises above the pre-specified level; and wirelessly communicating a second wireless signal from the EHS to the remote device for causing the light source be turned off or the cover to be closed, when the capacity or state-of-charge of the rechargeable battery reaches a pre-specified value.

  • Patent number: 9942854
    Abstract: An example computer-implemented method includes determining, by an electronic device, that the electronic device has not received a user activity for an interval of time. The method also includes determining, by the electronic device, a contextual state of the electronic device, and adapting, by the electronic device, a sleep delay value based on the determined contextual state of the electronic device. The method also includes determining that the interval of time has exceeded the sleep delay value, and responsive to determining that the interval of time has exceeded the sleep delay value, transitioning, by the electronic device, from a first power state to a second power state, where the first power state is higher or lower than the second power state.

  • Patent number: 9853458
    Abstract: The embodiments described herein include a transmitter that transmits a power transmission signal (e.g., radio frequency (RF) signal waves) to create a three-dimensional pocket of energy. At least one receiver can be connected to or integrated into electronic devices and receive power from the pocket of energy. The transmitter can locate the at least one receiver in a three-dimensional space using a communication medium (e.g., Bluetooth technology). The transmitter generates a waveform to create a pocket of energy around each of the at least one receiver. The transmitter uses an algorithm to direct, focus, and control the waveform in three dimensions. The receiver can convert the transmission signals (e.g., RF signals) into electricity for powering an electronic device. Accordingly, the embodiments for wireless power transmission can allow powering and charging a plurality of electrical devices without wires.

  • Patent number: 9847199
    Abstract: The switch device includes a control switch that turns on/off an electrical connection between an apparatus and the power supply, a condition judging circuit that judges conditions of driving the control switch, an electric wave reception circuit that receives an electric wave, and a power supply circuit that generates power from the electric wave received by the electric wave reception circuit. An electric wave transmission device that transmits an electric wave for making the switch device operate is arranged in a space, whereby the electric wave can be received by the electric wave reception device in the specific space. The switch device controls the control switch to be turned off/on when the electric wave is received. Alternatively, when the electric wave is not received, the switch device turns on/off the control switch.
