Abstract: A dual-interface computer interface card includes a circuit board. The circuit board includes an ExpressCard connector, a USB connector, a control circuit, a converter, two USB signal traces, two DC traces. The two USB traces are electrically connected with the ExpressCard connector and the USB connector respectively. The two DC traces are electrically connected with the converter and respectively with the ExpressCard and USB connectors. The control circuit, subject to the required DC operation voltage, is optionally connected with one of the two DC traces, while another DC trace is connected with the converter to convert its DC voltage level into the DC voltage level required by the control circuit. Accordingly, the computer interface card can be connected with the computer system optionally by one of the connectors thereof for transmission of USB signals therebetween.

Abstract: An information device includes a control board having a retaining portion mounted thereon, a shell sleeved onto the control board and having an end contacting against the retaining portion, and a sealing cap sleeved onto the other end of the shell. The sealing cap is engaged with the control board, relatively securing the sealing cap and the control board in position and confining the shell between the retaining portion and the sealing cap.

Abstract: An information means with waterproof and transmitting light characteristic is disclosed to include a connector, an electric device connected to the connector for data storage and transmission, a transparent waterproof member surrounding the connector around the electric device for protection against outside water, an outer layer surrounding the waterproof member and a part of the connector and the whole area of the electric device for protection against external heat energy, and a light guide extending from the transparent waterproof member to the outside of the outer layer for guiding light from electric device to the outside for visual check of the operation status of the electric device.
