Abstract: Various embodiments include an “Intuitive System” which detects the state of grid power at home or in commercial places and/or regions and manages the operation of various electrical and electronic systems accordingly. In various embodiments, a server may receive data from devices positioned throughout the grid. The server may aggregate, analyse, present, and/or act upon the received data. The system may enable providers to manage the health of grid power, monitor reports of power failures, analyse causes and durations of failures, engage in demand response, determine peak power demands, etc. The system may actively reduce demands for power, including, for example, by selectively reducing grid power available to constituents. However, constituents may have the capability to turn to back-up power systems, whose existence may be a determining factor in which constituents receive reduced grid power. The Intuitive System may also reduce grid load by turning down high-power devices.

Abstract: An apparatus, system and method for measuring quantity of a material are disclosed. One or more sensors are used to measure the quantity of the material are measured and error causing parameters are also measured. Error causing parameters are processed by executing one or more correction methodologies to determine a correction output. The quantity of the material is measured by using the correction output. One or values associated with the quantity of the material are measured and displayed. The one or more values are transmitted to a server and informative messages are received from the server.

Abstract: In the field of appliances connected to the power grid, it is sometimes desirable for such appliances to function even in the absence of grid power. Example applications include emergency lighting or public address systems. It is sometimes further desirable that such appliances be controllable in the absence of grid power, for example responding to commands to turn on or off. Appliances are described that can function in the absence of grid power, yet remain under control of a switch, actuator, or other control device. A control device may be local or remote. Appliances may be controlled via power-line communication. Appliances may sense the state of a switch even where other appliances are connected on a local circuit.
