The present invention provides an apparatus for expanding a serial communication port. The apparatus includes a first serial port, a second serial port and a processing and control module. The first serial port is used to transmit a first signal, and the second serial port is used to transmit a second signal. The processing and control module is coupled between the first serial port and the second serial port. The processing and control module includes a first serial bus host controller, a second serial bus host controller, a data forwarding unit and an expansion unit. The apparatus is connected between an electronic device and multiple peripheral devices, so that via the expansion unit, each peripheral device generates its own communication port on the electronic device.

System, apparatus and method for wirelessly expanding serial communication port between electronic computing device and its peripheral device

A signal adapter device for a display system which enables turning on and off the display device for energy conservation. The signal adapter has a signal input port coupled to a signal source, a signal output port coupled to a display, and an adapter port coupled to a sensor. Corresponding pins of the input and output ports are electrically connected to each other, except that the hot plug detect pin of the input port is electrically disconnected from that of the output port but is electrically connected to a hot plug detect pin of the adapter port. The sensor senses environmental conditions such as the presence of viewers within a certain distance, and generates a voltage signal for the hot plug detect pin. Based on this signal on its hot plug detect pin, the signal source determines whether to transmit multimedia data to the display device.
