Abstract: A modular dimmer assembly, including a communications circuit configured to send and receive wireless communication, a control circuit configured to receive an AC input at a first pulse width and adjust the brightness of at least one lighting device, in response to the communications circuit receiving a signal, by producing an AC output at a second pulse width, a regulation circuit, controlled by the AC output, including a flyback switch mode power supply (SMPS) and a capacitor, wherein the flyback SMPS charges the capacitor and the control circuit monitors a voltage of the capacitor to determine the second pulse width, and wherein the modular dimmer assembly is a two-wire device.

Abstract: One example embodiment relates to a water heater controller. The water heater controller includes an operating conditions circuit structured to receive temperature measurement signals indicative of temperatures over time of water in a tank of a water heater, and occupancy measurement signals indicative of whether individuals are present in an area proximate the water heater. A drift threshold circuit is structured to, in response to the occupancy measurement signals indicating that an individual is present or not present, define a plurality of drift threshold levels to trigger operation of a heating element of the water heater. A control circuit is structured to controllably operate the heating element based on the occupancy measurement signals and on the plurality of drift threshold levels.

Abstract: Systems and methods for interfacing a power line communications (PLC)-enabled communication device in a building with a power network are disclosed. In various embodiments, a system can include a specially-configured coupler that enables a common PLC communications signal to be injected into the same power phase line of the power network, but at different service panels.

Abstract: Devices and system for interfacing a power line communications (PLC)-enabled communication device in a building using three-phase power and two separate electric power meters are disclosed. In various embodiments, the system can include a specially-configured coupler that enables PLC communications signals to pass to all power lines but without interfering with the operation of the electric power meters.

Abstract: Devices and system for interfacing multiple power line communications (PLC)-enabled communication devices in a building are disclosed. In various embodiments, the system can include a high-frequency transformer coupled to a high-frequency communications device, a low-frequency transformer coupled to a low-frequency communication device, and one or more components adapted to appreciably abate distortion and/or attenuation of high-frequency signals passing through the first coupling device.

Abstract: A network topology and packet routing method for implementing a Local Area Network (LAN) using low-voltage (120/240VAC) power wiring as the transport medium. An Access Point (AP) having a Power Line Carrier (PLC) interface and one or more IEEE 802.3 Ethernet interfaces connects to the logical center of the Power Line medium via its PLC interface. Multiple User Terminals (UT) send to and receive from their associated AP, which in turn routes data packets toward the appropriate destination. Large networks may contain more than one AP, in which case each UT selects its AP based on a metric representing connection quality between the UT and the AP.

Abstract: A method and apparatus for modifying a three-phase power distribution network in a building in order to provide data communication by using a Power Line Carrier (PLC) signal to an approximate electrical central location point of Wye-connected and Delta connected power distribution system remote from the data entry point of the building. A passive coupler device is attached to a centrally located service panel. The passive coupler receives the Power Line Carrier (PLC) signal from the remote entry point in the building and conditions the signal for entry at the service panel onto each phase of the three phase power distribution network.
