Abstract: A wireless communication system and portable radio repeater are described. The system includes a portable magazine having multiple portable radio repeaters disposed therein. One or more of the repeaters are automatically or manually ejected based on a received signal strength measurement. Once ejected, each repeater communicates from the ejected location, automatically switching between passive and active receive modes based on received signal strength. The repeater has a sensor to transmit environmental data or a visual or audible locator. The magazine has a dispensing mechanism with a mechanical or electro-mechanical release mechanism that holds the repeater to be ejected in a substantially fixed position. The dispensing mechanism detects when the repeater switches to the active mode and dispenses the repeater in response thereto, as well as detecting the number repeaters remaining within the magazine and communicating this information.

Abstract: A user interface system (102) for a portable electronic device (100) is disclosed. The user interface system includes an interface (202) that is made of a flexible material and has an active position and an inactive position. The interface is coupled with a reservoir (204). The reservoir is used for storing electrorheological fluid (206). The user interface system also includes a source (208) that is coupled to the reservoir. The source is used for applying an electric field to the electrorheological fluid when the interface is in the active position.

Abstract: A wearable imager device comprises an imager body 9, a strap 27 attached to the imager body 9 and adapted to be fitted to and worn by a hand or finger of a user and an indicator light 29 to indicate an operation function of the device 21, wherein the indicator light 29 is incorporated in the strap 27. The strap 27 is conveniently made of a flexible material. The indicator light 29 may comprise a flexible light emitting band formed in the strap 27 in part or substantially all of the length of the strap 27.

Abstract: Mobile computing apparatus includes a portable computer (101) having a display module (105) and an arrangement (500) for providing illumination in the display module, the arrangement including a light source (222) external to the display module, a light guide (223) for guiding light from the light source toward the display module and a coupler (501) for coupling light from the light guide into the display module. The arrangement may be attached to a docking station (200) adapted to receive the portable computer.

Abstract: An antenna structure for use in a wireless communication device, the structure comprising (i) a plurality of antenna portions each having a substantially planar radiating surface and (ii) a conducting ground portion; wherein the radiating surfaces of the antenna portions are substantially parallel to one another in a side-by-side relationship and are substantially parallel to part of the conducting ground portion located behind the antenna portions with respect to a direction of transmission of radiation from the antenna portions, the conducting ground portion comprising a first part galvanically connected to each of the antenna portions and, electrically coupled to the first part, a second conducting part forming at least part of a cover for a wireless communication device.

Abstract: A method of programming a second security token using data stored on a first security token, wherein a privilege to be assigned to the second security token is selected by a user of the first security token. The user selects from privileges derived from a first set of privileges assigned the first security token. A file containing a definition of the privilege to be assigned to the second security token is transferred from an apparatus for programming security tokens to the second security token.

Abstract: A system for illuminating and reading information on a target (12) includes an illuminating device (14) for illuminating the target, separate from the illuminating device a user wearable reader device (11) for capturing an optical image of the target when illuminated by the illuminating device, detector means (30, 35) for detecting the location of the reader device and adjustment means (36, 22) for adjusting the illumination provided by the illumination device in response to a signal provided by the detector means so that a region (33) on the target illuminated by the illuminating means is readable by the reader device. A method of use of the system and an illumination unit for use in the system are also described.

Abstract: This invention relates to electronic equipment comprising microprocessors, and more specifically microprocessors employed within radio receiver circuits, incorporating on-chip memory (301, 302, 303) and which have the ability to operate in either a single chip or expanded mode. The single chip mode restricts microprocessor (300) operation to internal operation and thereby inhibits external addressing and locally generated noise whereas the expanded mode allows external addressing. A software program, comprised from modules of program code, is categorised into a first and a second category of routines. First category routines are related to equipment functions which are affected by generated noise to a higher degree and, when in operation, are stored in the internal memory (301, 302, 303). Second category routines are stored in a memory external to the microprocessor (201, 202) and are related to equipment functions which are affected by generated noise to a lesser degree.
