Abstract

Power consumption of an appliance under remote control is minimized. The appliance receives a wireless energy burst having a wireless magnetic resonating power coupling characteristic transmitted by a remote control device. The appliance is powered up from a powered-down state to a standby mode if the appliance is in the powered-down state when the wireless energy burst is received and the energy burst is of sufficient energy to activate a switched mode power supply of the appliance.

Claims

1. A remote control device, comprising:

a wireless power transmitter operable to transmit a wireless energy burst having a wireless magnetic resonating power coupling characteristic;

a processor and control element; and

a user interface having a power ON activation element;

wherein in response to activation of the power ON activation element of the user interface, the processor and control element controls the wireless power transmitter to transmit the wireless energy burst having the wireless magnetic resonating power coupling characteristic.

2. The device of claim 1, wherein the wireless power transmitter further comprises a magnetic resonator having a resonating frequency.

3. The device of claim 2, wherein the magnetic resonator comprises an inductor coil element and a capacitance plate element.

4. The device of claim 3, wherein the shape of the inductor coil element determines the resonating frequency of the wireless power transmitter.

wherein in response to the wireless power transmitter of the remote control transmitting a wireless energy burst that is received by the power antenna receiver of the appliance when the appliance is in a powered-down state, the processor and control element controls the switched mode power supply to power on the appliance from the powered-down state to a standby mode.

8. The system of claim 7, wherein the wireless energy burst beamed by the wireless power transmitter of the remote control is a magnetic resonating wireless transmission.

9. The system of claim 7, wherein the wireless power transmitter further comprises a magnetic resonator having a resonating frequency.

10. The system of claim 9, wherein the magnetic resonator comprises an inductor coil element and a capacitance plate element and wherein the shape of the inductor coil element determines the resonating frequency of the wireless power transmitter.

11. The system of claim 9, wherein the remote control device further comprises:

a processor and control element; and

a user interface having a power ON activation element;

wherein in response to a user activating the power ON activation element of the user interface, the processor and control element controls the wireless power transmitter to transmit the wireless energy burst having the wireless magnetic resonating power coupling characteristic.

12. The system of claim 7, wherein the wireless energy burst having the wireless magnetic resonating power coupling characteristic is beamed within a mid-range distance of the remote control device.
