System integration of wireless power transmission subsystem
First Claim
1. A system, comprising:
- a power source integrated with a host computing device, and configured to provide power to the host computing device;
a wireless power transmission module, coupled to the host computing device, configured to wirelessly transmit power derived from the power source, wherein the wireless power transmission module is to derive power from the power source during a plurality of operational states of the host computing device including a powered-off state; and
a controller to control power transmission by the wireless power transmission module including terminate active power transmission by the wireless power transmission module when a time duration during which the wireless power transmission module is kept active exceeds a time duration threshold, and terminate active power transmission by the wireless power transmission module when a remaining power level of the power source is below a power level threshold, wherein, to terminate active power transmission, the controller is to determine whether or not a control signal is detected on a Universal Serial Bus connection between the wireless power transmission module and the host computing device.

Abstract
In accordance with various aspects of the disclosure, systems, methods, and devices are disclosed that include a power source integrated with a host computing device, and configured to provide power to the host computing device, and a wireless power transmission module coupled to the host computing device. The wireless power transmission module is configured to wirelessly transmit power derived from the power source independent of whether the host computing device is in a powered-off state or not. The host computing device may be configured to stop the wireless power transmission based on a determination that at least one of one or more predetermined transmission policies has been violated or that an unrecoverable error has occurred at the host computing device.
