The interface device may have a waiting or a reset or an interrupting member coupled to the integrated circuit.

Abstract: A housing for computer or the like includes a front wall, a refractive planer member attached to the housing and having a rib or a swelling engaged into the housing, and a light device disposed in the housing for generating light through the planer member and toward the rib and the swelling, and for allowing the light to be seen through the rib or the swelling. The rib has two curved ends for flushing with the curved sides of the housing. The planer member includes a curved recess formed in a bulge and facing toward the light device for receiving the light generated by the light device.

Abstract: A computer facility includes a synchronizing interface device coupled between a high and a low speed processing devices for allowing the processing devices having different operating speeds or velocities to be suitably coupled and communicated with each other without occurring errors. The synchronizing interface device includes a read/write device coupled between the high and the low speed processing devices, and a delay counting device coupled between the processing devices and the read/write device for suitably communicating between the high and the low speed processing devices.

Abstract: A compact flash card device includes a board received in a housing, an L-shaped antenna member attached to the board and received in the housing, and a cover secured to the housing, to retain the antenna member and the board in the housing. Both the antenna member and the circuit board may be received and concealed within the housing such that the antenna member will not be exposed and will not increase the volume of the CF card device, and will not be stricken by the other objects, and will not be disengaged from the housing of the card device. A welding member may further solidly secure the antenna member to the board.

Abstract: A wireless network access facility includes one or more IEEE frequency devices, one or more multi-function actuating devices, and a processor device which includes a control device coupled to the IEEE frequency devices for determining a single or a multi-frequency mode, and a transmitting device coupled to the control device for checking identifications of users. An organizing device may be used for selectively operating various modes. A frequency control device may be used for converting frequencies and for transmitting with different frequencies.

A keyboard facility includes an interface device coupled to the interface facility, an electric power supply device coupled to the interface device to receive electric power from the computer facility, and a keyboard matrix device to detect and send signals of the keyboard assembly to the computer facility. A blue tooth facility is coupled to the interface facility, and includes a signal transforming device and an antenna to receive and send signals.

Abstract: A protective shielding device includes a circuit board having a notch and one or more holes formed in one side, and a shielding member engaged onto the circuit board for shielding the circuit board and having a leg extended from one side for engaging through the notch and for extending toward the lower portion of the circuit board. The leg includes one or more catches for engaging into the holes and for latching the shielding member to the circuit board. The other sides of the shielding member and the circuit board may then be secured together with fasteners.

Abstract: A circuit board includes an antenna having an extension extended from one end and secured to the circuit board and having a free end. A supporting member may be secured on the circuit board and disposed below the antenna for supporting the free end of the antenna. The extension of the antenna is preferably higher than the supporting member, for supporting the antenna member in an inclined position relative to the circuit board. The antenna preferably includes two or more legs engaged into and secured to the circuit board for solidly securing to the circuit board.

Abstract: A circuit board device includes a secondary circuit board supported on a primary circuit board and parallel to the primary circuit board for forming a compact structure. The secondary circuit board includes one end coupler for coupling to another coupler of the primary circuit board, and the other end having one or more rods supported on a frame for allowing the secondary circuit board to be stably supported on the primary circuit board. A housing may prevent the secondary circuit board from being interfered by the electromagnetic field of the primary circuit board.
