If a USB device is turned off or is not active, the device may be electrically disconnected from a USB host controller. The device may be electrically disconnected through a physical interface on the device. In some embodiments, if the device becomes active during a wait period (e.g., 2-3 seconds) prior to electrically disconnecting the device, the device may not be electrically disconnected. In some embodiments, when the device is electrically disconnected from the USB host controller and no system activity of a bus mastering peripheral is occurring, the CPU may enter a low power state if other conditions are met. In some embodiments, if the USB device becomes active after electrically disconnecting, the electrical disconnection may be discontinued.

A dual-sided smart card reader, and method for operating the same, is disclosed. The dual-sided smart card reader permits the simultaneous insertion of at least two different smart cards from opposing sides. The dual-sided smart card reader may additionally include a biometric verification device, such as a fingerprint scanner, for comparing biometric information from an operator of the reader to biometric information stored on a smart card.

The housing of a card reader has a connector to be inserted into an electronic equipment. When using a moving member movable in the inserting and removing directions (inserting direction and removing direction) of the connector and inserting the connector into the housing of the electronic equipment, the moving member is pushed by the circumferential portion of the counterpart connector of the electronic equipment connecting to the connector and moved in the removing direction of the connector to prevent a medium from being removed.

An electrical connector assembly for use with an input/output card comprises a cartridge defining a receiving space by a pair of side walls. The cartridge defines a front entrance for receiving a complementary connector and a rear portion for receiving a printed circuit board. A connector is assembled in the receiving space for mating with the complementary connector and includes a base plate having a mounting block formed thereon. The block defines a plurality of terminal passageways therein and a plurality of terminals is assembled in the terminal passageways for bridging the complementary connector and the printed circuit board. Latches formed between the cartridge and the connector near the front entrance releasably position the complementary connector therein. Hooks formed between the cartridge and the connector fixedly assemble connector to the cartridge. Mounting slots defined between the cartridge and the input/output card moveably and releasably assemble the cartridge to the input/output card.

A contact block for a smart card reader includes a plurality of contacts having first ends electrically connected to a printed circuit, and portions arranged to project beyond a surface of a contacts carrier and engage terminals of the smart card when the smart card is in an end position. A one piece switching contact also includes a portion that projects beyond the surface of the contacts carrier, the projecting portion extending into a path of the smart card to be engaged and moved by the smart card as the smart card is moved to the end position. A second portion of the one piece switching contact faces the printed circuit and is moved into engagement with a conductive path of the printed circuit as a result of engagement and movement of the first portions ofthe switching contact in response to movement of the smart card into the end position.

An IC card reader/writer having a body which includes an IC insertion slot and an operation display section. The body is separable into an upper cover and a lower portion. The upper cover and the lower portion are displaced from each other to form a step on the side of the body formed with the IC card insertion slot. Further, a rack recessed from the step is formed on the portion of the body having the IC card insertion slot. Furthermore, the surface of the upper cover is curved upward in the direction away from the IC card insertion slot in such a manner as to increase the thickness progressively toward the side of the body far from the IC card insertion slot, and a display section is located on the slope of the curved portion. The operating area of the IC card reader/writer has function keys.

A board adapter for electrically connecting an electrical card connector to a mother board, comprises 68 signal holes, 100 conductive pads, a plurality of signal traces, a first grounding means, a transforming unit and a second grounding contact. The first grounding contact surrounds the signal holes and is electrically connected with a corresponding grounding contact of the electrical connector, for providing the signal holes and the electrical connector with grounding protection. The second grounding contact is alternately juxtaposed with every two of the signal traces for providing grounding protection. The conductive pads are electrically connected with either the signal traces or the grounding contacts. The transforming unit includes two power traces to separately bear two different strength voltage induced currents. When either of the traces bears a corresponding voltage induced current, the other trace can be transformed into a grounding trace to protect the bearing trace.

A card read and write controller for use in a personal computer according to the present invention includes a voltage generator for supplying a power voltage to the chip-in card when the chip-in card is inserted into a card insertion slot; a clock generator for supplying an initial clock signal to the chip-in card. A bus interface serves the host controller, while a serial port accommodates serial data communication with the host controller. A bootable read-only-memory (ROM) provides a booting control program, a common random-access-memory (RAM) stores operational and program data, and a central processing unit (CPU) controls activation of a light-emitting-diode (LED) indicating the insertion or ejection of the chip-in card, generates the interrupt signal, and checks whether data transmitted to the card and data received from the card are identical with each other to determine that the inserted chip-in card is an authorized card for the personal computer system.
