Self-powered devices and methods
First Claim
1. A self-powered device configured to selectively communicate with a remote computing device, the self-powered device comprising:
- a power circuit electrically coupled to a bus;
a processor electrically coupled to the bus;
a memory electrically coupled to the bus, said memory comprising;
instructions for selecting one of a plurality of modes of operation, wherein the plurality of modes of operation include a first mode of operation in which the self-powered device consumes less than a pre-determined or adaptively-determined amount of power and a second mode of operation in which self-powered device consumes more than the pre-determined or adaptively-determined amount of power;
instructions for conserving power by alternating between the first mode of operation and the second mode of operation, such that the self-powered device is in the second mode of operation during pre-determined or adaptively-determined time intervals, and wherein a duty-cycle of the second mode of operation relative to the first mode of operation is in accordance with a power budget for the self-powered device; and
instructions for communicating with the computing device only during the second mode of operation.

Abstract
A system includes a computing device that selectively communicates with a self-powered device. The self-powered device has several modes of operation, including a first low-power mode of operation and a second high-power mode of operation. The self-powered device is to communicate with the computing device when the self-powered device is in the second mode of operation. The self-powered device may conserve power by alternating between the first mode of operation and the second mode of operation such that the self-powered device is in the second mode of operation during pre-determined or adaptively-determined time intervals. A duty-cycle of the second mode of operation relative to the first mode of operation may be in accordance with a power budget for the self-powered device.
