  • Publication number: 20140055341
    Abstract: A control system for controlling an external device based on images obtained by a control device comprises a detecting module, an obtaining module, and a determining module. The detecting module generates an obtaining signal when the control device establishes a communication with the external device. The obtaining module obtains an image of the current environment around the external device in response to the obtaining signal. The determining module determines whether at least one predefined object contained in the obtained image. When there is no predefined object contained in the obtained image, the determining module further determines whether the external device is in a first state and generates a first control signal when the external device is not in the first state. The external device switches to a first state for powering off the backlight of the external device in response to the first control signal.

  • Publication number: 20130346779
    Abstract: A waking device for controlling an electronic device connected to the waking device from a first state to a second state. The electronic device receives signals from a portable external device and is unable to execute a corresponding operation based on the received signal. The waking device comprises storage with a predetermine parameter, a processing module, and a triggering module connected to the processing module. The processing module processes the received signal from the portable external device to obtain a waking parameter and compares the waking parameter with the predetermined parameter in the storage. When the waking parameter matches the predetermined parameter, the processing module generates a waking signal, and the triggering module controls the electronic device to switch from the first state to the second state in response to the waking signal, the electronic device is enable to execute a corresponding operation based on the received signal.
