What changed

This document is a publication of a patent application filed by Lutron Technology Company LLC. The application describes a supplemental power supply system for battery-powered devices. The system is designed to intelligently manage power by switching between the primary battery and a supplemental source (e.g., solar, RF power) to power control and communication circuits, potentially extending device operational life or reliability.

This is a patent application, not a regulation, and therefore does not impose direct compliance obligations. However, it represents innovation in power management for battery-operated devices. Companies involved in manufacturing such devices, particularly those incorporating advanced power management or alternative energy sources, may find the disclosed technology relevant for competitive analysis or potential licensing opportunities.

Abstract

A battery-powered device, such as a motorized window treatment, may provide power to an electrical load, such as a motor. The device may also include a control circuit and a communication circuit. In addition to the battery, the device may be configured to receive power from a supplemental power source, such as a solar cell or wireless RF power supply, through which to power the control and communication circuits. The device may include a voltage monitor and a switch to intelligently control whether the battery or the supplemental power source is powering the control and communication circuits.
