Abstract

Methods and devices are provided. One device includes an antenna, a microcontroller, and a power source. The power source configured to generate power in response to ambient energy received at a first frequency during a cycle of energy harvesting using the antenna. The power is transferred to a power storage cell such that when the power storage cell has an amount of power the microcontroller of the device processes at least a part of a processing task to be sent to an end node, and a result of processing of said at least said part of the processing task is stored. During one or more additional cycles of energy harvesting, using generated power to process one or more additional parts of the processing task to assemble a payload or process a wireless transmission of the payload. The wireless transmission of the payload is sent over a second frequency to the end node.

Dependent claims

A device, comprising,

an antenna;
a microcontroller;
and
a power source configured to generate power in response to ambient energy received at a first frequency during a cycle of energy harvesting using the antenna, the power being transferred to a power storage cell such that when the power storage cell has an amount of power the microcontroller of the device processes part of a processing task to be sent to an end node when the processing task is complete, wherein a result of processing of said part is stored before the amount of power is exhausted;
wherein during one or more additional cycles of energy harvesting, using additionally generated power that meets the amount of power for the microcontroller to continue performance of said processing task that was previously started, said continuance of performance causes processing of one or more additional parts of the processing task to assemble a payload for said processing task when complete so that a wireless transmission of the payload is triggered, wherein the wireless transmission of the payload is sent over a second frequency to the end node.
