Abstract: A USB (Universal Serial Bus) hub with built-in storage device is comprised of an upstream interface port to be operated under the USB (universal serial bus) transmission control protocol for serving as a data-switching communication port of relevant devices; a hub device, further comprising a hub control unit, a packet-switching unit, a router, a built-in storage device, and a repeater; and a downstream interface port to be operated also under USB transmission control protocol, being provided with a plurality of interface ports to serve as a data-switching communication port of relevant devices. Therefore, the USB hub of the present invention can serve as an interface for switching connection between USB interfaces with different transmission speeds, such as USB1.1 and USB2.0, for data transmission.

Abstract: A multi-functional electronic card with a multi-I/O interface has a plurality of interface ports for connecting to a host, at least one functional device, and a multi-interface and multi-functional controller. When an interface prot is inserted into the host, other interface ports are off-line automatically. The multi-interface and multi-functional controller is connected to a multi-I/O interface and the functional devices for selecting one functional device. Signals of the multi-I/O interface are converted into signals of the selected functional device so that the host can access the selected functional device.

Abstract: A separable multi-interface I/O card device comprises an I/O bridge and an I/O device. The I/O bridge includes a host interface for coupling to an electronic device, a bridge unit, and a first I/O bus, wherein the bridge unit is adapted to either convert signals from the host interface into signals of the first I/O bus or convert signals from the first I/O bus into signals of the host interface, and supply power from a power pin of the host interface to the first I/O bus. The I/O device includes an I/O functional unit and a second I/O bus mated with and separably coupled to the first I/O bus so as to send power, I/O, data, and control signals from the host interface to the I/O functional unit.

Abstract: There is disclosed a global positioning system electronic card capable of dynamically plugging navigation information, which includes a multi-interface controller, a dynamic insertion/removal card interface for being dynamically inserted with a memory card stored with map data, a GPS module, and a host interface. When the memory card is inserted into the dynamic insertion/removal card interface, the dynamic insertion/removal card interface notifies the multi-interface controller for further informing the host device through the host interface to read the map data in the memory card, thereby displaying a corresponding map. After determining the positioning coordinate, the GPS module notifies the multi-interface controller for further informing the host device through the host interface to read the positioning coordinate determined by the GPS module, which is compared with the map data read previously, thereby labeling a coordinate position on the map.

Abstract: The present invention discloses an electronic card with multiple interfaces, which includes a first and a second interface connection port, an interface signal converter, a first and a second switch device and a card loading detection device. The interface signal converter converts second interface connection port signals to predetermined interface signals. The first switch device is arranged between the second interface connection port and the interface signal converter. The second switch device is arranged between the interface signal converter and the predetermined interface. The card loading detection device detects whether the first interface connection port is connected to an electronic device. If the first interface connection port is connected to an electronic device, the card loading detection device turns off the first and second switch devices.
