Abstract: A scanning device for capturing images, which contains an optical unit comprising a light source (3), a light guide (2), and a light receiver (5). The light guide (2) comprises a substantially parallel sided, transparent member, the member having first opposed ends (10, 13) extending between the parallel sides (11, 12), one of the ends (10) facing the light source and extending non-orthogonally between the parallel sides, the other end (13) facing the image to be scanned in use, and second opposed ends (14, 15) extending between the parallel sides and the first opposed ends. Light from the light source (3) enters the light guide through the one first end (10), is directed onto the image after passing out of the other first end (13), is reflected back into the light guide and then directed by the light guide towards the light receiver (5). The arrangement is such that one portion of the reflected light passes to the light receiver (5) without being reflected by the second opposed ends while another portion of the reflected light passes to the light receiver after being reflected by one or both of the second opposed ends, the two portions being directed to different parts of the light receiver, the device further comprising a filter through which one of the light portions passes while the other does not.

Title: Snatch alarm mounted on carrying strap of bag
Inventor: SCHOFIELD DAVID MICHAEL
IPC: G08B13/14
Filed: 2002-06-25
Abstract: An anti theft alarm for a bag attached to an existing carrying strap 8 comprises a first housing 5 and a second housing 6 held together by an elasticated band 10 (see figs 2 and 4). The first housing contains an alarm (buzzer), a power source and a reed switch. The second housing contains a magnet 7. The housings together form a hole 9 into which the strap 8 is folded (fig 3).

Title: A filter system
Inventor: CASE ANDREW CHARLES
IPC: C02F3/06
Filed: 2002-09-05
Abstract: A filter system comprises a transparent container 1 in communication with the inlet of a non-transparent container 2 that contains two filter layers 7, 8 placed above a bio - medium 9. Below the bio - medium is a sump 10 and the inlet of a pipe 11 which transfers filtered water out of the system. Preferably water enters the filter system through an inlet 3 and is sprayed through spray bars 4 onto a tray 5 supporting a first filter 6. The water then passes through the two filter layers 7, 8 which are preferably made of foam before proceeding through the bio-medium and the sump prior to exiting the system via the pipe 11. Preferably natural ultra-violet light from the sun sterilises the water in the transparent container thus eliminating a need for high energy consuming ultra-violet sterilisers. Advantageously the filter system is ecologically friendly and provides naturally occurring conditions such as sunlight and bacteria to assist the filtration process.

Title: RF base station data repeater
Inventor: SCOTT LOGAN
IPC: G01S19/48
Filed: 2001-06-06
Abstract: A data repeater system (20) is added to a wireless communications network which increases user data rates at the periphery of the cellular coverage area by boosting the downlink (base station to mobile user) signal and uplink (mobile user to base station) signal. The data repeater system (20) includes a signal tagging means (61) which adds a unique electronic signature to the repeated signal such that position determination errors due to a non-line of sight propagation path can be corrected. The repeated signal is received and processed with a location measurement unit to determine the time of arrival and to extract the signal tag of the repeated signal. The time of arrival measurement and recovered signal tag are then processed at a mobile location center to determine the true position of the transmitter.

Title: Screen mounting apparatus
Inventor: FRITSCHE MARK
IPC: G09F15/00
Filed: 2002-09-13
Abstract: The present invention defines a screen mounting apparatus for mounting a graphic display screen for use with display stands or booths, such as those used in trade shows and other exhibitions. The apparatus of the present invention is designed to receive, generally by adhesive affixation, a display graphics screen such that generally the entire length of one of the screen edges is affixed to the apparatus, with the length of the screen edge and the apparatus generally equaling that of the corresponding display frame segment. Additionally, the screen mounting apparatus includes an elastic portion which permits a limited degree of spring-like movement when force is placed upon the screen at assembly and disassembly. This permissible movement, in combination with the discussed distributed affixation technique, means that the tension force required to mount the apparatus and the affixed screen to a display frame is distributed along the entire surface of the apparatus and screen, and not at isolated fastening points.
