Abstract: A standby power controller that is adapted to remove the electric power from the attached devices when an attached television is determined to be not in use. The controller includes a data communication link adapted to provide data communication with a co-located set top box so as to allow the transfer of usage information from the set top box to the standby power controller.

Abstract: An In Home Display (IHD) device adapted to display electricity usage of a household in data communication with a Smartmeter and in data communication with an intelligent power manager. The IHD provides a channel for the transmission of household descriptive data to the intelligent power manager. The intelligent power manager communicates with a number of IHDs each associated with a respective household. The intelligent power manager will process and compare data from the IHDs prompting a householder to take actions based on said comparison.

Abstract: An electronic device having a light display for communicating messages to a user wherein the light display is a rectangular halo produced by several discrete light sources where the combined width of all the light sources is small in comparison to the length of the perimeter of the rectangular halo.

Abstract: A hub device controls an electrical energy state of one or more appliances, and controls an alternative electricity supply such as a solar generation installation whose output is non-constant such that sometimes the electrical energy available from the alternative electrical supply is greater than the electrical energy demand from the appliances, and at other times the electrical energy available from the alternative electrical supply is less than the electrical energy demand from the appliances. The hub device may control the alternative electricity supply and/or the appliances such that the electrical energy available from the alternative electrical supply is matched to the electrical energy demand from the appliances.

Abstract: An energy saving device monitors computer activity to determine if the computer is in active use, and if not in active use, it commands the computer to power down to a low energy use power state (and cut power to computer peripherals) unless a user indicates otherwise. The device also communicates the computer's energy usage (as well as energy usage of peripherals) to a remote management center associated with the electricity supply network supplying the computer. When electricity usage needs to be reduced in the electricity supply network, the remote management center sends a demand response event request to the computer, with the request commanding the computer to enter a low energy power use state unless its user indicates otherwise. If the user signifies that the low energy power use state should not be entered, the computer instead enters an intermediate reduced energy use power use state.

Abstract: An electrical device is described that is adapted to be installed by connection to a mains electricity supply, the electrical device including communication means adapted to communicate to a monitoring entity, such as an energy company or similar, when the electrical device is installed.

Abstract: A computer implemented system and method for demand management in an energy supply network including aggregation of energy use modification offers from energy consumers in order to meet value offers from energy suppliers.

Abstract: A set top box is configured to detect that a television (or other electrical device) connected to the set top box is not in use, and places the television (or other device) into a lower energy usage state. The set top box includes a controlled power outlet adapted to provide power for the electrical device, a switch adapted to control power to the controlled power outlet, and a sensor adapted to sense at least one characteristic of the power drawn through the controlled power outlet, wherein the switch is operated in response to the sensed characteristic. For example, if the set top box has a television drawing power from the controlled power outlet, and the sensor senses that the television is in a decreased-power “standby” state, the switch may cut power to the controlled power outlet to avoid the parasitic power loss incurred by the standby state.
