Abstract: A CWUSB, ExpressCard card has a body with an internal slide in the form of a deep rectangular slot. Accommodated in the slot is an aerial unit in two parts pivotally connected together. The slot has sides to the slot and slightly over-hung ends. The first part has a major portion with a width to slide in the slot and a minor portion with a reduced width that is able to protrude between the over-hung ends in an extended position of the aerial unit. The minor portion has pivot points. The second part is longer and has the reduced width whereby it can pass between the overhung ends. The inner end of the second part has complementary pivot points, whereby the parts are pivotally connected. The parts molded to locate a torsion spring, which biases the second part upwards with respect to the first part.

Abstract: A CWUSB interface 1 is shown installed in a printer 2. The interface allows a computer 3 to send print data to the printer, either wirelessly or in a hard wired manner, for which the computer has an auxiliary communication card 4 having an aerial 5 and the usual Type A USB socket 6. A cable 7 is provided for wired connection. The interface 1 has a WUSB controller 8 with an aerial 9 connected to it, which can co-operate with the aerial 5. The interface also has a Type B USB socket 10 for wired connection. A peripheral device controller 11 is connected to either of the socket 10 or the WUSB controller 8 via a pair of switches 12,14. These are under control of the WUSB controller. Being a wireless device, it can communicate with the computer only if the interface is associated with the computer, that is to say the computer as its host has recorded the full ID of the interface, the interface has recorded the full ID of the host and the host and interface have exchanged encryption keys.

Abstract: A peripheral device for a host computer comprises: means for physical connection of the device for its powering by and communication with the host computer; a manual switch on the device for powering down and up of the device; and circuitry in the device enabling it to perform a function of the device, the circuitry being connected to the computer via the physical connection when in use and to the manual switch for communicating to the host computer in response to actuation of the switch: a first signal when the device is powered up for initiating in the host computer a hardware-removal routine causing the peripheral to draw substantially less than normal or no power and a second signal when powered down to cause the host computer to initiate a peripheral-detection-and-power-up routine.

Abstract: A hub has a case with an up-stream Type A USB socket in a top surface and four down-stream Type A sockets in the side surfaces. The hub has internal circuitry interconnecting the ports. Unconventionally for a USB up-stream port, the power contacts of the Type A up-stream socket are provided with a voltage across them for powering the transceiver. However, this is switched off as follows to allow wired transfer of data from the computer, without voltage being passed back the computer.

Abstract: A hand-held electrical device (10) such as a mobile telephone, includes a carrier (11) formed by a thick (over 2 mm) plate of insulative material having a plurality of recesses that receive electronic components. The periphery of the carrier forms most of the periphery of the electronic device. A circuit board (52) with traces thereon lies facewise adjacent to a face of the carrier. Electronic components lying in recesses of the carrier, are connected by resilient blades to conductive traces on the circuit board.

Abstract: A method and system for providing a group of users with a search facility for information stored at a plurality of addressable logical locations is described. A database of index information where information is stored at a plurality of logical locations is provided. The index information includes the address of the logical locations and the descriptive information for information stored at each logical location. The descriptive information matches a common profile of interest to the group of users. Accessing and retrieval of stored information by a user in the group is monitored and descriptive information is derived using the retrieved information. The relevance of the retrieved information is determined by comparing the descriptive information to the profile. If the retrieved information is determined to be relevant, the database is updated using the address and the descriptive information of the determined relevant retrieved information.

Abstract: In a connection assembly (15) of printed-circuit board and connector, a printed-circuit board (16) and a connector (17) can be fixed positionally accurately in relation to one another by means of position holders (36, 37) provided on the connector (17). The position holders are constituted of soldering pins (36, 37) and the printed-circuit board (16) is provided with soldering pads (46, 47) which can be connected to the opposing soldering pins (36, 37) by soldering. There is provided in this manner a connection assembly (15) of printed-circuit board and connector in which the positionally accurate fixing of a printed-circuit board (16) and a connector (17) is more easily produced and more precisely assembled than has been possible to date.

Abstract: A PC card with a circuit board (14) and sheet metal cover parts (16, 17), is provided with a shielded volume (23, 29) where a circuit component (24) is isolated from circuit components outside the shielded volume. An internal shield (18) of electrically conductive material surrounds the shielded volume, and is engaged with a ground trace (28) on the circuit board. The internal shield is flexible so it bends when the sheet metal cover parts bend, to avoid breaking the circuit board. Layers of electrically conductive adhesive (42, 44, 46) couple the internal shield to the circuit board into one of the cover parts. A plate-like shielding device (40) can be provided, that includes a metal foil (41) that is bonded to the internal shield and that lies over the entire shielded volume.

Abstract: A PC card is provided with internal electromagnetic shielding to isolate two or more different circuit component areas of the card, which facilitates mounting of the shielding. In one card which is an extended card having a standard forward portion (102) containing electronic components, and having an extended rearward portion containing an antenna (100) for radiating electromagnetic energy, the shielding includes a strip-shaped portion (22) of electrically conductive material that extends across the width of the circuit board and that has opposite ends that terminate near the intersection between the two card parts, with the shielding having pins (31) that project into holes (150) in the circuit board.
