Abstract:
A power-saving remote control apparatus (40) includes a remote control receiving unit (1022) and a main control unit (104). The main control unit (104) is configured to control the power-saving remote control apparatus (40) to enter a working mode when a controlled apparatus (30) needs to be turned on. The main control unit (104) is configured to control the power-saving remote control apparatus (40) to enter a sleeping-power-saving mode when the controlled apparatus (30) stops working, and then for every first predetermined time, the main control unit (104) is turned on to wake up the remote control receiving unit (1022) to scan a plurality of wireless signals (52). The main control unit (104) is configured to control the power-saving remote control apparatus (40) to enter the working mode if the wireless signals (52) include a wireless starting signal (54) for starting the controlled apparatus (30).
Abstract:
Disclosed herein is a remote control apparatus for communicating with an electric apparatus by radio communication, including: a plurality of operation keys; a transmission/reception section for transferring a signal to and from the electric apparatus by the radio communication; and a control section having at least a power control function for controlling the power of the remote control apparatus; the control section controlling the transmission/reception section to a normal power state until a predetermined period of time elapses after a signal is inputted thereto by an input of any of the operation keys to enable transfer of a signal from the electric apparatus by the transmission/reception section, the control section controlling the transmission/reception section to a low power consumption state after the predetermined period of time elapses.
Abstract:
A center device performing power feed control generates a control signal for controlling supply and suspension of power to a main load of a remote terminal and transmits the control signal by superimposing the control signal on the power to be supplied to the remote terminal. The remote terminal includes a power-receiving side unit, a switch that connects the power-receiving side unit with the main load when the switch is on and disconnects the power-receiving side unit from the main load when the switch is off, and a control signal receiver that receives the control signal superimposed on the power transmitted from the center device to turns the switch on or off in accordance with the control signal received at the control signal receiver.
Abstract:
A wireless control device may include an antenna and a power harvester configured to generate power for the device from a radio frequency signal incident on the antenna. The device may further include an upconverter stage comprising a first port to receive a control signal to be upconverted and a second port to receive the incident radio frequency signal and to output the upconverted control signal at upper and lower sideband frequencies. The antenna may be coupled to the second port.
Abstract:
A remote control for an electronic device includes a plurality of keys, a power supply, a power control unit, a code modulating unit, and a transmitter. The plurality of keys generates different first electrical signals when actuated. The power supply is operable to power the remote control. The power control unit detects a voltage of the power supply, and generates a second electrical signal when the voltage of the power supply falls below a predetermined value. The code modulating unit generates different key code signals according to the different first electrical signals, and a switch code signal according to the second electrical signal. The transmitter converts the different key code signals and the switch code signal into different wireless signals, and transmits the different wireless signals to the electronic device.
Abstract:
The present invention is related to a multi-function remote control which is supplied power by a rechargeable battery. The multi-function remote control comprises a micro controller unit (MCU), a residual power display, a button unit, a current detector and a voltage detector. The MCU couples to the rechargeable battery and then charges or discharges the rechargeable battery. The current detector measures the current of the rechargeable battery and correspondingly outputs a current-value signal (Si) to the MCU. The voltage detector measures the voltage of the rechargeable battery and correspondingly outputs a voltage-value signal (Sv) to the MCU. Then, the MCU obtains the residual power of the rechargeable battery by means of analyzing the current-value signal (Si) and voltage-value signal (Sv), and then reveals the corresponding residual power by the residual power display. Whereby, the multi-function remote control might have functions of remote control, charging and revealing residual power.
Abstract:
A receiving module, checking module, and a controller are provided. The receiving module is configured for receiving external wireless signals. The checking module is configured for checking whether a current wireless signal comprises checking codes of a control signal which is configured for controlling the electronic device and, if yes, generating an activation signal. The controller is configured for switching the electronic device into a power-saving mode if no external wireless signal is received after a predetermined time period and switching the electronic device into a normal mode if the activation signal is received.
