Abstract: A system and an apparatus for controlling electric power supply and methods therefore are described. In particular, a system and an apparatus for powering down an electronic device and methods therefore comprises a device and a sensor. The sensor is configured for transmitting a sensing signal to the device via a communication protocol. The device comprises a processing module for receiving and processing the sensing signal, and powering down operation of the device in an event the sensor detects that the device is operating in an absence of the user.

Abstract: A system and an apparatus for controlling electric power supply and methods therefor are described. In particular, a system and an apparatus for powering down an electronic device and methods therefor include a device for communicating with a user, a processor for determining electric power supply to the device, and a sensor for monitoring presence of the user.

Abstract: The present invention generally pertains to a sensor (101), more particularly the present invention pertains to sensors for saving energy, wherein the sensor (101) comprising at least one input (11) for receiving signal, at least one output (12) for transmitting signal, and at least a sensing module (14) for sequentially sensing at least one activity of a user and determining power supply to at least one appliance by tracking a sequential predetermined period of time and detecting at least one activity.
