Abstract: A device for controlling and integrating multiple types of signal transmission cables includes a multi-signal transmitter module and a multi-signal receiver module. The multi-signal receiver module is connected to the multi-signal transmitter module via a network cable for receiving a first and a second differential signal sequentially transmitted by the multi-signal transmitter module. The multi-signal receiver module also performs a differential solution process for the received first and second differential signals, so as to get a first control instruction and a video signal, which are then sequentially transmitted to at least one electronic device for the same to execute a corresponding operation. With these arrangements, multiple signals can be transmitted and received with reduced quantity of cables, and the controlling and integrating device can be installed and maintained with reduced labor cost.

Abstract: An energy-saving audio-amplifier control device is electrically connected to an amplifier for sensing an audio signal input state at a sound-source input end of the amplifier and controlling the on/off of the amplifier accordingly. The control device includes a signal detection module, a control module and a power control module. The signal detection module detects the state at the sound-source input end and generates a first signal to the control module. Based on the first signal, the control module controls the power control module to control the on/off of the amplifier. With these arrangements, it is able to automatically control the amplifier to off when the audio signal input to the amplifier is ended, and accordingly, achieve the purpose of saving energy, reducing power consumption, and minimizing loss of components.

Abstract: An energy-saving control device for remote image receiver is disclosed. The control device is electrically connected to an image receiver, and includes a detection module, a control module, and a power control module. The detection module detects a differential signal transmission state at the remote image receiver, and generates a detection signal to the control module accordingly. The control module generates a control signal according to the detection signal, so as to control the power control module to control on/off of power supply to the image receiver. With these arrangements, it is able to control the image receiver to automatically turn off when the differential signal transmission stops, so as to achieve the effects of energy saving and extended service life of the image receiver.
