Abstract:
A system and method for remotely controlling the power states of a device. A system comprises a power supply, and a wireless receiver. The power supply supplies main power and standby power. The wireless receiver is coupled to the power supply. The wireless receiver receives wirelessly transmitted signals to cause the system to transition between an "OFF" state in which main power is disabled and an "ON" state in which main power is enabled, and between the "ON" state and a "SLEEP" state in which system power consumption is reduced in relation to the "ON" state.
Abstract:
System comprising at least one master unit and a plurality of slave units, wherein said master unit and said slave units comprise means for performing communication via radio frequency channels. The at least one master unit comprises means for transmitting control signals to said slave units, and the slave units are each provided with a unique address and are each associated with a controllable device. The at least one master unit comprises means for executing a sequential transmission of control signals to at least one of said slave units.
Abstract:
[Object] To provide an electronic apparatus and a control method therefor, that are capable of reducing power consumption. [Solving Means] The electronic apparatus having a normal mode in which first electric power is consumed and a power-saving mode in which second electric power lower than the first electric power is consumed includes a first sensor and a second sensor whose power consumption is lower than that of the first sensor. In the power-saving mode, supply of power to the first sensor is restricted, the second sensor is set to the power-saving mode, a trigger for restoring the power-saving mode to the normal mode is detected by using the second sensor set to the power-saving mode, and the power-saving mode is restored to the normal mode based on the detected trigger.
Abstract:
System comprising at least one master unit and a plurality of slave units, wherein said master unit and said slave units comprise means for performing communication via radio frequency channels. The at least one master unit comprises means for transmitting control signals to said slave units, and the slave units are each provided with a unique address and are each associated with a controllable device. The at least one master unit comprises means for executing a sequential transmission of control signals to at least one of said slave units upon activation of a function control key. The master unit is configured for transmitting a status request signal to a slave unit that has received a control signal, which status request signal is transmitted after a time delay corresponding to the time taken by the slave unit to perform an operation in response to the received control signal.
Abstract:
The invention describes a method of actuating a switch (S) between a device (Di) to be controlled and a power supply (P), which method comprises the steps of generating a first electrical signal (14) in a remote control unit (10) and converting the first electrical signal (14) into electromagnetic radiation (EM) by means of a first transmitting antenna (Ti) of the remote control unit (10). A first detecting antenna (Ri) of a remote control interface module (20) of the device (Di) to be controlled detects the electromagnetic radiation (EM) to obtain a second electrical signal (24), which is passively converted into a switch actuating signal (25). The switch actuating signal (25) is actuated to switch the device (Di) to be controlled between an operating mode in which current is drawn from the power supply (P) by the device (Di) during operation, and an inactive mode in which the device (Di) is completely disconnected from the power supply (P) so that no current is drawn by the device (Di). The invention further describes a system (1) for actuating a switch (S) between a device (Di) to be controlled and a power supply (P). The invention also describes a remote control interface module (20) and a remote control unit (10).
