  • Patent number: 11368046
    Abstract: The present disclosure relates to a power supply management system adapted for use with at least one utility proxy power source, to help control powering a load when an AC mains power source is not available to provide power to the load. The system has a power converter forming an uninterruptible power supply, and includes a controller configured to control operation of the power converter. A supplemental battery subsystem is included which is in communication with the power converter for supplying DC power to the power converter. The controller monitors the application of power from the utility proxy to the load and uses the DC power supplied by the supplemental battery subsystem, when needed, to supplement the generation of power by the power converter, to thus assist the power converter in powering the load along with the power being provided by the utility proxy.

  • Patent number: 11246207
    Abstract: Smart switch devices, systems, and methods for modifying an existing electrical system to utilize the power state output of a physical switch as an indicator or signal for the operation of a smart home device or system or network of such devices to facilitate interoperability of physical switches with smart devices. The smart switch detects or determines the power state of a circuit and infers the corresponding state of a mechanical switch that operates the circuit. This information is then transmitted to associated smart devices, which may not be physically connected to the circuit controlled by the switch. When the mechanical switch is operated, it can control both electrically attached loads, such as a conventional light appliance, and wirelessly control unconnected smart devices.
