Systems, apparatus, and methods for controlling power modes in electronic devices are provided. A system may include an electronic device and an input device that sends power mode selection information via a network to a power mode selection receiving component in the electronic device. The electronic device includes a first power component that powers a first component, and a switching component that controls the first power component. The electronic device may include a second power component that powers a second component. The switching component may control the second power component. The power mode selection receiving component and the switching component may be powered independently of the first and the second component. If the power mode selection information indicates an off mode, the electronic device may provide power to the power mode selection receiving component and the switching component and not to the first and the second component.

This disclosure provides systems, methods and apparatus for waking a wireless power transmitter from beacon mode. In one aspect a wireless power receiver apparatus is provided. The wireless power receiver apparatus includes a receive circuit comprising a receive coil. This receive circuit is coupled to a load. The receive circuit is configured to wirelessly receive power from a transmitter device at a first power level to power the load. The wireless power receiver apparatus further includes an adjustment circuit configured to be powered by using the wirelessly received power. The adjustment circuit is further configured to adjust a characteristic of the load using the wirelessly received power for a period of time to cause a detectable change in an operating characteristic of the transmitter device for the period of time.

A system for switching on an electrical device includes a startup circuit for an associated electrical device. The electrical device has a main power circuit comprising first and second paths and a main switch for selectively connecting the electrical device with an associated power source. The startup circuit uses a pulse of electromagnetic energy transmitted wirelessly from an associated remote control device to form a third path, whereby power is supplied from the associated power source for actuating the main switch.
摘要:
An energy usage coordinator controls the energy usage of individual buildings of a group (or portfolio) of buildings in one or more load zones. These buildings have all contracted with an energy company which controls (directly or indirectly) the energy usage coordinator. By agreeing to lower energy usage during times of peak usage (when the energy company may otherwise have to pay very high prices on the spot or short term market), the owners or managers of the buildings receive a preferential energy rate from the energy company. Such a preferential rate may be in the form of a fixed rate reduction or a variable rate reduction. Alternatively, the energy company may determine that the energy is currently selling for twice what its building portfolio has contracted to pay for it so it requests some portion of the portfolio to reduce usage so that it can sell the excess/saved energy in the market.

A system of one embodiment is disclosed that includes a load, a power supply, and a mechanism. The load is operable in a default mode and an alternate mode. The load has better performance in the default mode than in the alternate mode, and consumes less peak power in the alternate mode than in the default mode. The power supply is connectable to an external power source to provide voltage to at least the load. The mechanism causes the load to operate in the alternate mode upon detecting the voltage provided by the power supply dropping below a predetermined threshold level than a predetermined threshold number of times.
