Abstract: A method for security and/or automation systems is described. In one embodiment, the method may include receiving, at a power adapter, power from a power supply, routing a first portion of the power received from the power supply to the doorbell unit, and routing a second portion of the power received from the power supply to both the device of the doorbell unit and the doorbell chime when the doorbell button is being actuated. In some cases, the power adapter is wired, via doorbell wiring, to at least one of a doorbell chime, a doorbell unit, and the power supply. In one example, the first portion of power is routed to power a device of the doorbell unit when a doorbell button of the doorbell unit is not being actuated.

Abstract: A system and method of managing the operation of a remotely controllable control unit for an appliance in a building during peak power demand hours with an application on a mobile device further in communication with a vehicle having a rechargeable battery capable of providing power to a power grid is disclosed. The application determines a state-of-charge of the rechargeable battery in the vehicle, and determines a location of the vehicle and whether the vehicle is within a threshold distance to the building. The building is preconditioned using the appliance to a preferred state if the vehicle is within the threshold distance to the building. When the vehicle arrives at the building, it is electrically connected to the power grid to provide electricity from the rechargeable battery to the power grid to replace the power used during the preconditioning.

Abstract: A system may have a power adapter with multiple ports for supplying power to electronic devices. The electronic devices may include devices such as cellular telephones, wristwatch devices, laptop computers, and tablet computers. The power adapter may supply power using wired links and wireless links. An online user account that is maintained on computing equipment in the system can communicate with the electronic devices or power adapter over a communications network. The power adapter and other components of the system may gather information such as user device charging priority settings, battery charge state information, device type information, usage history information, calendar information, and other information. This gathered information may be used in identifying an optimum power transfer strategy for the power adapter to use in transmitting different amounts of power to each of the electronic devices.

Abstract: A wireless power supply system includes a power transmission device having a power transmission coil and a power receiving device having a power receiving coil. The power receiving device calculates a first efficiency based on a transmission power command value and the electric power supplied to the battery. The power transmission device calculates a second efficiency based on a phase difference between a voltage and a current supplied to the power transmission coil. The power transmission device controls electric power supplied to the power transmission coil according to the transmission power command value, and regulate the electric power supplied to the power transmission coil when the first efficiency falls to a predetermined first threshold efficiency or less or when the second efficiency falls to a predetermined second threshold efficiency or less.

Abstract: A charging method is provided for an electronic device. The charging method includes monitoring a current capacity of a battery coupled to a first electronic device to obtain a current level of remaining power in the battery and receiving a control command. The control command is used to instruct the first electronic device to enable a charging module and then to use the charging module to charge a second electronic device based on the current level of the remaining power in the battery. The charging method also includes receiving an operation command. In response to the operation command, the charging method further includes determining a first capacity of the battery based on the current level of the remaining power in the battery, and then controlling the charging module to provide electric power for the second electronic device based on the first capacity of the battery.

Abstract: A charger including a class E power driver, a frequency-shift keying (“FSK”) module, and a processor. The processor can receive data relating to the operation of the class E power driver and can control the class E power driver based on the received data relating to the operation of the class E power driver. The processor can additionally control the FSK module to modulate the natural frequency of the class E power transformer to thereby allow the simultaneous recharging of an implantable device and the transmission of data to the implantable device. The processor can additionally compensate for propagation delays by adjusting switching times.
