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: A multi-functional electronic card capable of detecting removable cards includes at least one functional device, a controller, a host interface, and a removable card interface. The host interface has a card detecting pin fixed at a level representing that a card is inserted. The removable card interface has an elastic switch connected to the device detecting pin of the controller. The controller detects event and status of a card insertion and removal by a level change of the device detecting pin for setting the event and status in a status register, and informs the host device through the host interface so that the host device reads the status register to determine whether the removable card is inserted or removed.

Abstract: A multi-function electronic card has a host interface, a multi-functional controller and a plurality of function devices. Each function device is connected to the host via the host interface by issuing an interrupt request to the multi-functional controller. The multi-functional controller has an interrupt queue and an interrupt status register, each bit of the interrupt status register corresponding to a function device. When a function device issues an interrupt request, an identification number of the function device is stored into the interrupt queue, and only when all the bits in the interrupt status register are zeros, a corresponding bit in the interrupt status register is set as 1 for issuing an interrupt request to the host. When the host has serviced the function device, the interrupt queue is updated and the interrupt status register is cleared.

Abstract: An electronic card capable of changing communication functionality of a coupled electronic device is disclosed. A removable interface has at least a card detection pin which is set at a first state or a second state based on the coupled electronic device. A functional module provides a communication functionality via an access bus or a specific application bus based on whether the card detection pin is at the first state or the second state. A bridge is provided for bridging and converting signals of the interface bus on the removable interface into signals of the access bus or the specific application bus, or vice versa. A multiplexer device selects signals of the access bus or signals of the specific application bus based on whether the card detection pin is at the first state or the second state for being switched to the interface bus.

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.
