Title: Telecommunications apparatus
Inventor: BARNES NIGEL EVERARD
IPC: H04M1/733
Filed: 1991-01-23
Abstract: Telecommunications apparatus is provided for use in the cordless telephone environment where a number of handsets are arranged to communicate with a plurality of base stations. When a handset indicates that it wants to communicate with a base station it may be recognised by a base station which is not necessarily the nearest one for best reception. The base station, before setting up a link, compares the received signal strength with a predetermined stored threshold level. If the signal strength is above the level, the base station immediately attempts to set up a link. If it is below the level, the identity of the handset is stored and if the same base station receives a subsequent request from the same handset it then attempts to set up a link with that handset. <IMAGE>

Title: Detecting particular constituents in an atmosphere using electron capture      detectors
Inventor: FOX SHAW GRANT
IPC: G01N33/00
Filed: 1992-03-26
Abstract: A sample of the atmosphere is drawn along two flow paths, each containing a respective electron capture detector 27, 28. The two electron capture detectors are run in parallel using different carrier/purge gases in each. One detector uses a carrier/purge gas eg N2 that produces relatively low energy electrons which are easily captured while the other detector uses a carrier/purge gas eg Ar that produces relatively high energy electrons which are difficult to capture. The gas of interest may be drawn from the atmosphere through a membrane 22 which does not pass oxygen, into a carrier gas such as argon. The flow path may contain a common (42) or individual chromatographic columns 25, 26. The system may be used to detect explosives which are delayed relative to halogenated hydrocarbons in the columns 25, 26. The relative response of the two detectors distinguishes explosives, which are strongly electron capturing from other compounds with lower electron capturing ability. <IMAGE>

Title: Deletion of entries from the channel mapping list of a videocassette recorder.
Inventor: HAILEY JAMES EDWIN
IPC: H04N5/7826
Filed: 1992-04-27
Abstract: In a videocassette recorder including VCR PLUS TM  capability and autoprogramming capability, the channel-mapping procedure may be greatly simplified by using the autoprogramming feature to locate and program all active channels, and then by mapping only those channels which are active, instead of requiring the user to select all 125 possible channel-programming positions. It is desirable that the autoprogramming scan list and the channel guide list be independently modifiable. In one embodiment, the performance of an autoprogramming function resets the lists to a state in which both lists contain identical data. The channel mapping is between expected transmission channel and actual channel when, for example, the programme is transferred to cable. <IMAGE>

Title: Subjective eyesight and visual display unit visibility test
Inventor: MURRAY IAN JAMES
IPC: A61B3/08
Filed: 1993-04-22
Abstract: A computer-based procedure uses a combination of software and ancillary equipment to test various aspects of the computer user's eyesight and screen quality. Test patterns are presented on the screen 2 while the ancillary equipment (e.g. linear polarising filters 5, 6 mounted on the screen 2 and 3, 4 in front of the user's eyes) allows control over which pans of the test patterns are seen by each eye. By determining the smallest size of test pattern that can reliably be identified, monocular or binocular visual acuity can be estimated. By detecting misalignment of detail seen by each eye, ocular co-ordination can be estimated. The visibility of detail on the screen can be assessed by presenting targets at various screen locations. Areas where the user cannot accurately identify detail indicate localised impairment of visibility, due to such factors as on-screen glare from light sources, or poor or uneven screen quality.   <IMAGE>
