Abstract: A micro card and the passive commutate device suitable for micro card, wherein the micro card is a micro card designed in a theory of micro and is configured with micro controller and substrate of repeating read-write memory and transmit part connect electrically with the substrate. The transmit part of the micro card is designed into a universal interface to support the transfer of sign of interface of various application device. The micro card link with a pre-set passive commutate device, a first standard interface disposed on the passive commutate device. The first standard interface is for memory card interface, and connect electrically with universal interface and couple with memory card of application device. By micro card sense automatically, judge the interface type supported by the passive commutate device to switch to corresponding work model to save outer date to repeating read-write memory of micro card.

Abstract: A universal micro memory card having a unique common transmission interface designed according to USB specifications and equipped with both USB pins and data transmission pins; said universal micro card detects the type of system interface connected to it with the initialization signals sent from the system end via the USB pins (D+ and D−), and then switches to the corresponding working mode; in that way, said universal micro memory card enables signal transmission from/to different memory card systems via said common transmission interface.

Abstract: The XD memory card adapter of the present invention is comprised of an adapter board, a first pin set, a second pin set and a plurality of connecting lines; it can be used in cooperating with a memory card reading/writing device. The memory card reading/writing device has at least an insertion slot having therein a memory card electric interface, and is characterized by that: the adapter board can be inserted into the insertion slot to make connection of the first pin set with the memory card electric interface in the insertion slot; and the adapter board is provided on the side in opposition to the first pin set with the second pin set, the first pin set is connected with the second pin set via the connecting lines.

Abstract: The present invention discloses a high-speed serial bus power supply device to connect a 4-PIN cable receptacle and a USB interface socket on a notebook. It includes a first connector, which is a common 6-PIN cable receptacle and can be connected to an appropriate interface; a second connector, which is a 4-PIN cable plug connected to the first connector and can be inserted into the said 4-PIN cable receptacle of the notebook; and a USB plug, which is also connected to the first connector and can deliver power to the serial port through said USB interface socket which is connected to the notebook.

Abstract: A card switch device comprises a base plate and a base frame at least, and the base plate is electrically connected to a socket on the side thereof. The base frame has a groove retaining contact elements of memory cards of not less than two standards. Thus, the card switch device can provide use for one or more memory cards.

Abstract: This invention provides a device combining a slim CD-ROM drive and a flash memory card drive, which utilizes the unused space in a slim CD-ROM drive to mount a flash memory card socket to form a combined device. It comprises of a seat with the first containing space and the second containing space. The first containing space hosts a circuit board and a driving unit, a standard CD-ROM drive with a panel on the front and the panel has a opening against the second containing space, a flash memory socket in the second containing space and its slot faces against the said opening of the panel. The socket can hold multi types of flash memory cards, including SD, MMC, and MS cards. Furthermore, there are multi PINs in the socket and they are connected to the circuit board on one end and contact the flash memory card on the other end to support access to the flash memory card.

Abstract: This invention relates to a large volume storage device with a memory card-adapting interface to transfer data from/to digital electronic devices with a second socket. The said storage device comprises of a circuit board, a power supply unit connected to the circuit board to deliver power to the said storage device, a storage media connected to the circuit board through a transfer interface, and an simulated card adapting interface that has a standard plug structure on one end to connect the said large volume storage device to the said socket and a interface cable on the other end, which is connected to the circuit board. With the help of the operating interface (display, browse, or delete) of the said digital electronic device, the standard instructions and control commands of the simulated card can be translated into instructions and control commands that can be identified by the storage device through the simulated card-adapting interface, in order to transfer data from the card to the storage device.
