Abstract: The present invention includes a housing for carrying the components or circuits. The housing include a first part that is located in the slot when the present invention is inserted into the computer. The second part of the housing extends outside the slot of the computer. A wireless transmission module is set in the second part for transmitting the signal. A SIM is set also in the second part of the housing. A hot swapping protector is located in the first part of the housing and electrically coupled to the SIM for protection. A card reader is connected to the hot swapping protector and a power control module is connected to the card reader, the hot swapping protector for providing the power.

Abstract: The present invention provides a sucking disk type USB extension socket for plugging with a USB device. The USB extension socket comprises a USB seat and an extension transmission cable. The USB seat has a connection socket therein, which is electrically connected to one end of the extension transmission cable. The other end of the extension transmission cable has a USB connector. At least a sucking disk is disposed on the USB seat. The USB seat can be fixed at any position through the design of the sucking disk type fixing structure thereof. The present invention has the advantages of high space usage and convenient and flexible use.

Abstract: The present invention discloses a saving power architecture for card reader and network apparatus. The present invention includes PCMCIA interface and a main power source coupled thereto. A network power and a card reader power are respectively connected to the PCMCIA interface and the main power source for operating the card reader and network. Network apparatus is connected to the network power and the card reader is also connected to the card reader power for reading the information stored in the memory card. Associated software or driver is coupled to the PCMCIA interface for driving the network apparatus or card reader. A control unit is used to control the driver or the software.

Abstract: A dual-purpose connector assembly includes a stand, a first electrical connector, an electrical cable and a second electrical connector. The stand has a base adapted to be placed on a table surface, and a prop formed with a first cable passage that extends along a vertical axis. The base has a surrounding wall, and is formed with a second cable passage that extends from the first cable passage to the surrounding wall. The first electrical connector is mounted on the prop and is adapted to connect electrically with the peripheral device. The electrical cable has a first end connected to the first electrical connector, and a second end opposite to the first end, and extends through the first and second cable passages. The second electrical connector is connected to the electrical cable and is adapted to connect electrically with an electronic device.

Abstract: A stack-type expansible electronic device includes a primary circuit board unit and at least one auxiliary circuit board unit. The primary circuit board unit includes a primary substrate having first and second major surfaces, which are respectively formed with substrate terminals and board terminals that extend transversely therefrom. One of the first and second major surfaces is further formed with a signal distribution circuit that is connected electrically to the substrate and board terminals. The auxiliary circuit board unit includes an auxiliary substrate having third and fourth major surfaces, and a set of conductive vias that extend from the third major surface through the fourth major surface and that permit the substrate terminals to extend respectively therethrough such that the auxiliary substrate is spaced apart from the primary substrate and such that the conductive vias are connected electrically to the signal distribution circuit via the substrate terminals.

Abstract: A PC card having automated Drag and Sleep function is equipped with Drag and Sleep control circuit to connect to the controller of the PC card, a connector unit and the other devices. As the connection of the connector unit to the external system (the external networks or devices) is cut off, the Drag and Sleep control circuit generates and transmits interrupt-signal to the controller to enable the PC card to get into sleep state; when the disconnected connector unit is once again connected to the external system (such as the external networks or devices), the Drag and Sleep control circuit generates and transmits interrupt-signal to the controller to enable the PC card to resume normal state, thus the PC card can effectively save energy because it can greatly lower the electric current consumption under the sleep state.
