Abstract: An intelligent water-monitoring system includes a water-monitoring device installable inline with a building water system (e.g., at an inlet of the system). A plurality of sensors of the water-monitoring device are configured to sense properties of the building water system, such as water pressure and water flow. The water-monitoring device has a valve and a controller configured to automatically shut the valve in response to sensed data indicating a possible problem in the building water system. The intelligent water-monitoring system may include an app executable by a computing device to display information based on the sensed data.

Abstract: An AC fixture has one or more AC sockets, and a port powering or charging device with one or more ports. The port powering or charging device has a circuit board with a power circuit which is configured to convert AC power, from AC wires connected to the AC socket, to DC power. The power circuit is configured to deliver the DC power to the one or more ports, which may be a USB, FireWire, mini-USB, HDMI or other port or combination of ports. In a further example, a communication circuit provides signal and data connections over the AC wiring, to one or more of the ports. In a still further example, a lamp or other indicator visible on a faceplate of the device is activated upon a reversed connection of the AC wires, to alert an installer or a user of a wiring fault.
