20090309852 | TOUCH PANEL INPUT DEVICE AND CONTROL METHOD THEREOF - A touch panel input device includes a touch panel, an analog multiplexer and an embedded controller. The touch panel generates a plurality of analog signals when the touch panel is touched. The analog multiplexer is communicated with the touch panel. The embedded controller is communicated with the analog multiplexer for generating a select signal to the analog multiplexer. The analog multiplexer sequentially outputs one of the analog signals to the embedded controller according to the select signal. The analog signals are converted into corresponding digital signals by the embedded controller. | 12-17-2009 |
20100090970 | ELECTRONIC APPARATUS WITH TOUCH FUNCTION AND INPUT METHOD THEREOF - 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. | 04-15-2010 |
20100097357 | COMPUTER AND METHOD FOR CONTROLLING EXTERNAL DISPLAY DEVICE - A computer has a hardware layer module, a driver layer module, and an application layer module. The hardware layer module has a number of interface ports, and a preset interface port of the interface ports is coupled with the external display device. When the external display device is coupled to the hardware layer module via the preset interface port, the driver layer module outputs a notify message to the application layer module and controls the hardware layer module to read hardware information of the external display device. In addition, upon receiving the notify message, the application layer module can read the hardware information from the hardware layer module via the driver layer module and control the driver layer module to provide multiple displaying modes to the hardware layer module according to the hardware information. Thus, the external display device is enabled to display a video in a suitable displaying mode. | 04-22-2010 |
20100169900 | System and Method for Driving Hardware Device and Processing Data - A system for driving a hardware device and processing data and a method thereof are provided. The system includes a storage unit, a processor, and the hardware device. The storage unit stores a multimedia application interface, a virtual window driving model (WDM) interface, and a multimedia application. The processor is electrically connected with the storage unit and used for executing a multimedia application. The hardware device receives or outputs first format data. When the multimedia application and the hardware device are active, the multimedia application interface and the virtual WDM interface are taken as communication interfaces between the multimedia application and the hardware device, and the virtual WDM interface converts the first format data to second format data and transmits the second format data to the multimedia application via the multimedia application interface, and the second format data is processed by the multimedia application. | 07-01-2010 |
