Abstract: The present disclosure relates to a power supply management system adapted for use with at least one utility proxy power source, to control powering first and second loads when an AC mains power source is not available to provide power to the loads. The system uses an internal DC bus of a power converter to receive power from a utility proxy, and a DC/DC converter/charger of the power converter to receive power from a short term supplemental battery subsystem. The DC/DC converter/charger is used to supply a first AC output signal to power the first load. An AC/DC rectifier of the power converter uses the DC power from the utility proxy, supplied onto the internal bus, to generate a second AC output signal which is applied independently to the second load to power the second load fully independently of the first load.

Abstract: An intelligent graphic human/machine interface unit (GHMI) for a power controller device detects, via visual sensors, a user proximate to the device and transitions from “sleep” to “command” mode. When in “command” mode, a user may authenticate themselves to the device, and provide (e.g., in “active” mode) control input for executing device functions, either via a touchscreen display of the GHMI unit or via unlock and command gestures manually performed by the user, detected by the visual sensors, and decoded by the GHMI controller. Command gestures may be mapped to specific control functions and/or command sequences commonly executed by the power controller device. By allowing a user to provide authentication and control input via signed gestures, a user wearing protective gloves or other protective gear precluding use of a capacitive touchscreen may interact with, monitor, or manage the power controller device normally.
