METHODS AND APPARATUS FOR ELECTRONIC DEVICE POWER

摘要

Improved mechanisms for automated control of harvested energy delivery are described. A device harvests and stores energy and activates a controller when a sufficient level of stored energy is achieved. The controller retrieves previous power-off state information determines status information, and activates and powers a powered device. Just before insufficient energy remains to power the powered device, the controller stores shutdown status information and enters a power-off state.
