Abstract: A portable electronic apparatus and a connection method therefore are disclosed. The portable electronic apparatus comprises a connector, a processing circuit, and a switch module. After a plug is plugged into the connector, the processing circuit reads a voltage value of the plug via the switch module. When determining that the voltage value of the plug is within a first voltage range, the processing circuit outputs switch signals to the switch module, so that an input signal of the plug is able to be transmitted to the processing circuit via the connector and the switch module. When determining that the voltage value of the plug is within a second voltage range, the processing circuit outputs other switch signals to the switch module, so that an output signal of the processing circuit is able to be transmitted to the plug via the switch module and the connector.

Abstract: An ExpressCard solid-state storage device is disclosed herein, which receives an access command coming from a computational device and accesses data accordingly. The ExpressCard solid-state storage device includes a circuit board, an ExpressCard interface, a flash memory, and a controller. When the ExpressCard interface of the storage device is inserted into a corresponding interface of the computational device, the ExpressCard solid-state storage device is electrically connected with the computational device. Then the controller receives a write, read or erase command, which is from the computational device and through the ExpressCard interface, and writes data into the flash memory or reads/erases data from the flash memory accordingly.

Abstract: A protection mechanism for terminals of memory stick adapter includes two outer casings, a circuit board unit, and a framework. Multiple plugging terminals disposed to one end of the circuit board unit for connecting to the memory stick are covered up or exposed by means of a mobile protection cover. A locating groove is disposed on a sliding plate each provided on both sides of the cover An elastic arm on an inner edge of each of both sides of the framework is disposed with an inclined protruding block to secure the cover in conjunction with the locating groove. The block breaking away from the locating groove as the elastic arm moves out upon insertion of the memory stick to retreat the cover and expose those plugging terminals for facilitating insertion of the memory stick.

Abstract: A card reader with multiple slots to convert data stored in electronic cards in different format into the interface format of Express Card™ and to output the converted data to a computer includes an insulation casing, two slots, one Express Card™ connector, and data relay unit to convert the data storage format of an electronic card into the interface format of Express Card™ and to output the converted data through the Express Card™ connector; each slot being divided into multiple terminal sets to respectively connect to multiple electronic cards for reducing the space of the card reader, facilitating portability, and better adapting to expansion medium used by mobile commerce or traveler.
