Abstract:
An audio signal switching apparatus at least comprises an audio jack, a speaker jack, a detection circuit and a control circuit. The audio jack and the speaker jack are separately configured in a computer system. The detection circuit detects whether the computer system is turned on or turned off. The control circuit is connected to the detection circuit and electrically connects the audio jack to the speaker jack when the computer system is turned off.
Abstract:
A computer device includes a controller, a power supply circuit and a universal serial bus (USB) module. The controller is used for transmitting a data signal. The power supply circuit is used for supplying operating power. The USB module includes a USB bridge and a core circuit. The USB bridge is used for transmitting the data signal, and it operates according to the operating power generated by the power supply circuit. The core circuit operates according to the operating power generated by the power supply circuit.
Abstract:
An electronic apparatus with a touch function includes a screen and an input device. The input device includes a transparent plate and a signal detector. The transparent plate and the signal detector are disposed on the screen, and the signal detector is electrically coupled to the electronic apparatus through a connecting interface. The signal detector has a detecting range on the transparent plate and detects a location of a target object located within a detecting range by a non-touch detecting way to generate a first coordinate data, such that the electronic apparatus controls an operation thereof according to the first coordinate data.
Abstract:
A power control method is used with a video camera of a computer system. The power control method includes steps of executing a virtual web camera software to load a virtual web camera, executing a video application program such that the virtual web camera software generates a power-on message, and providing electric energy to the video camera in response to the power-on message.
Abstract:
A portable device integrated with external video signal display function is provided. The device includes a video input interface, a display panel, a display chip, and a panel controller. The video input interface receives an external video. The display chip outputs an internal video. The panel controller includes a first input interface, a second input interface, and an output interface. The first input interface is coupled to the video input interface to receive the external video. The second input interface is coupled to the display chip to receive the internal video. The output interface is coupled to the display panel. Whether the display panel displays the external video or the internal video is determined according to an internal instruction.
Abstract:
A computer system and an auxiliary message displaying device and method thereof are provided. The auxiliary message displaying module applied in a computer system comprises a processing unit, a display unit and a display driving unit. The computer system comprises a host, a main monitor and an operating system. The processing unit receives and processes a first data and then outputs a second data. The display unit is for displaying a message. The display driving unit controls the display unit to display message according to the second data. The driver of the operating system retrieves a message from the operating system and obtains the font corresponding to the message from the font database, and then the message is processed to generate the first data. When the host is at a standby mode, the auxiliary message displaying module operates and displays message using the standby power of the host.
