Self-powered devices and methods
First Claim
1. A device, the device comprising:
- a processor;
a memory storing instructions, which, when executed by the processor, implement one or more power management procedures for selecting one of a plurality of power-consumption modes of operation of said device, wherein the instructions for selecting one of the plurality of power-consumption modes of operation include instructions for conserving power by transitioning a portion or an entirety of one or more sub-systems of the device from at least a first power-consumption mode of operation to a second power-consumption mode of operation to meet a current power budget of said device; and
an energy collector configured to collect energy to power the device from an environment surrounding the device, wherein the energy collector is configured to operate at a pre-determined or adaptively-determined optimal operating point, such that an output voltage at a desired output current is designed to yield maximum power from available input energy collected by the collector from the environment.

Abstract
The self-powered device is configured to be powered by energy collected from a surrounding environment. The self-powered device includes an energy collector, and a memory having instructions for selecting one of a plurality of modes of operation. The energy collector is configured to collect energy to power the self-powered device from a surrounding environment in which the self-powered device is located. The plurality of modes of operation include: (i) a low-power mode of operation in which the self-powered device consumes less than a pre-determined or adaptively-determined amount of power and the self-powered device uses less than its full capabilities, and (ii) and a high-power mode of operation in which self-powered device consumes more than the pre-determined or adaptively-determined amount of power and the self-powered device uses its full capabilities. The instructions for selecting one of a plurality of modes of are configured to (a) select the low-power mode of operation when available energy becomes insufficient to fully power the self-powered device, and (b) select the high-power mode of operation when sufficient energy again becomes available to fully power the self-powered device.
