Abstract

Official abstract text for this publication.

A method, device, and system for controlling power delivered to a power-consuming device. The device can harvest power from a conductor carrying a high voltage using a power harvesting device. The device can include a power storage device to power a hardware processor and a communication component when there is no voltage flowing through the conductor. The device can determine when a control event is to occur. At such time, the device terminates control power delivered to the power-consuming device and continues to withhold the control power until the control event expires. When the control event has ended, the device allows control power to flow to the power-consuming device. The device uses a timer and the communication component to send and receives signals associated with a control event to a user. The device can also operate in a limited mode to conserve power when the device is not in use.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for controlling power delivered to a power-consuming device, the method comprising: receiving, from a current transformer, a low voltage energy signal harvested from a high voltage energy signal generated by an energy source; conditioning, using a power storage device conditioner of a load control switch, the low voltage energy signal to generate a trickle charge; charging a power storage device of the load control switch using the trickle charg…
