Device with dual power sources
First Claim
1. A method comprising:
- at a wearable device that includes at least one sensor, a primary power supply and an auxiliary power supply, receiving a signal indicative of an availability of the auxiliary power supply to provide power to the wearable device; and
responsive to receiving the signal, the wearable device operating the auxiliary power supply to supply power to the wearable device, wherein the primary power supply uses a first type of energy to power the wearable device and the auxiliary power supply uses a second type of energy to power the wearable device, wherein the first type of energy is different from the second type of energy.

Abstract
A wearable device includes a sensor, auxiliary electronics, a primary power supply configured to harvest radio frequency (RF) radiation received from an external reader and use the harvested RF radiation to power the sensor, and an auxiliary power supply configured to harvest energy other than that received from the external reader and use the harvested energy to supply power to the sensor and/or the auxiliary electronics. The external reader may supply less power in response to operation of the auxiliary power supply. Additionally or alternatively, in response to a determination that the auxiliary power supply is unable to supply power, the wearable device may disable all auxiliary electronics but for the sensor. In response to a determination that the primary power supply is unable to supply power but the auxiliary power supply is able to supply power, the wearable device may retain operating parameters in the memory storage unit using the auxiliary power supply.

21. A non-transitory computer readable medium (CRM) having instructions stored thereon that, when executed by one or more processors associated with a wearable device, cause the wearable device to perform operations, the operations comprising:
-
receiving a signal indicative of an availability of an auxiliary power supply to provide power to the wearable device, the wearable device including at least one sensor, a primary power supply and an auxiliary power supply; and responsive to receiving the signal, operating the auxiliary power supply to supply power to the wearable device, wherein the primary power supply uses a first type of energy to power the wearable device and the auxiliary power supply uses a second type of energy to power the wearable device, wherein the first type of energy is different from the second type of energy. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
