Abstract: An ExpressCard device is applied to a computer system, and comprises a USB connector, an ExpressCard interface connector, and a control unit. The USB connector is used to connect with a USB interface provided by the computer system, the ExpressCard interface connector is used to connect with an ExpressCard interface provided by the computer system, and the control unit is used to transmit data to the computer system via either the ExpressCard interface connector or the USB connector at the same time. The ExpressCard interface connector is based on the USB standard so that the ExpressCard interface connector or the USB connector is connected with the control unit via a same USB signal pin. Thereby, the present invention allows a single ExpressCard device without an adapter to be applied to the computer system with different connection interfaces.

Abstract: A plug used for connection with a USB receptacle. The plug contains a plurality of metal contacts, which is used for contacting metal contacts of the USB receptacle when the plug is connected to the USB receptacle. It also contains a loader, which is used for loading the metal contacts of the plug. The plug has a thickness that is smaller than an ordinary USB plug, so it can be utilized by electronics that have a thickness less than an ordinary USB plug.

Abstract: A touch panel apparatus with optical detection for location has at least one photographic fetching unit and a signal analysis unit. The photographic fetching unit is used to photograph a surface of the panel and a touching object on the panel, and then export a video signal. The analysis unit receives the video signal and analyzes it to obtain a location of the touching object on the panel. The panel can be a liquid crystal panel or a planar screen of a display or a projected plane by a projector.

Abstract: An input system for coordinate and pattern includes a pen and a photographic device affixed on the pen, suitable for use on a panel. The photographic device can photograph the panel by a photographic image region and is coupled to a control unit. According to the image pattern of the photographic image region, an image discerning analysis is performed for detecting the coordinate of the photographic image region. The displacement, speed, handwriting, and direction can also be analyzed out. Moreover, the photographic device can photograph the image pattern, and serve as a scanner when the pen moves. The pen can also touch the panel with at least one setting pattern, and exports a keyboard button signal, so as to simulate a keyboard function. The system can also include at least a detection device and a control button for use in operation.

Abstract: A touch panel display aiding interface performs the operations of a computer pointing device on a touch panel display screen. The touch panel display aiding interface comprises a pointing object, at least a button object and a rolling-action object shown on the touch panel display screen. When the user by means of a pointing member touches the button object on the touch panel display screen, the aiding interface simulates a mouse pressing. When the user touches the rolling-action, the aiding interface simulates a mouse rolling. When the user touches the button object while moving the pointing member, the pointing object moves along with the pointing member.
