Title: Piston for internal combustion engine
Inventor: OVERSBY GRAHAM
IPC: F16J1/04
Filed: 2000-10-07
Abstract: An engine piston 10 has a crown portion 12 generated about a longitudinal piston axis 14 and, extending axially from the crown, a pair of gudgeon pin bosses 26, 28 defining a pin axis 30 and spaced apart at opposite sides of an orthogonal thrust axis 40. A circumferentially discontinuous skirt defines lateral thrust and non-thrust bearing regions 34 and 36, respectively, centred on the thrust axis, each joined by convexly bowed reinforcement ribs 62, 64, 66, 68 to the bosses. The bearing region 36 on the non-thrust side of the piston is circumferentially shorter than thrust region 34, reducing piston mass to one side of the piston, and the reinforcement ribs are offset in pin axis direction where they intersect the bosses. Mass reducing recesses 106, 108 are formed in the underside of the crown between the unskirted periphery 37, reinforcement ribs and bosses, the offset ribs 66, 68 permitting the recesses to extend further as at 110 and permit greater reduction in mass. The asymmetry of mass reduction permits bosses and pin axis to be offset towards the thrust region 34 whilst having the centre of mass of the piston acting through or near the pin axis.

Title: Assay of micro-organisms in cell cultures
Inventor: BRADBURY DAWN ANN
IPC: C12Q1/04
Filed: 2000-11-08
Abstract: Micro-organisms which over-produce ATPase, especially mycoplasmas in a sample of a cell culture, are detected by making use of the ATPase activity to convert cellular or externally added ATP to ADP. The decrease in ATP externally added or the increase or absolute level of ADP produced from cellular ATP can then be detected or measured. For example, if a reagent such as phosphenol pyruvate/pyruvate kinase is added to convert that ADP back to ATP, the resulting high level of ATP can be detected bioluminescently using the reaction:<BR> <BR> Luciferin + luciferase enzyme + ATP   T   h  n   + products.

Patent GB-2384355-A (GB)
Title: Biometric sensor
Inventor: SWATTON STEWART NATHAN RIDGLEY
IPC: G06K9/00
Filed: 2002-01-18
Abstract: A biometric sensor (50) comprises a detector array (52) and a planar slab waveguide (56). Diode laser arrays (58, 60) are arranged to couple light into the planar slab waveguide. A ridge of an individual's fingerprint or palmprint, when in contact with the planar slab waveguide at a point of contact therewith, causes a fraction of the light within the waveguide to become unguided at the point of contact, said fraction being detected by the detector array. The sensor has reduced complexity compared to similar sensors employing fibre-optic faceplates and also provides for removal of noise in fingerprint images formed by the sensor, said noise arising from accumulation of dirt or grease on the sensor. An interference filter (55) acts to reduce the solid angle of diverted light arriving at the CMOS detector (52) improving resolution.

Patent GB-2394385-A (GB)
Title: Provision of services via a mobile telecommunications network
Inventor: BROOKES MARK ANDREW
IPC: H04W4/02
Filed: 2002-10-15
Abstract: When a user makes a location specific request to a service provider, the user's request is intercepted by the network which generates a "user tag". The network stores user information in the tag, encodes it and transmits it to the service provider in a form which the service provider is unable to obtain the users identity. All of the data exchanges between the user and the service provider are routed through the network, using the user tag to identify the user. In this way, information identifying the user is never provided to the service provider who cannot therefore directly access the user. The user tag may have a predetermined short lifetime to provide further security. The lifetime of the user tag is extended if the user makes further requests relating to the same service, so that all requests relating to a service are dealt with by using one user tag.

Title: Matching information over a network by comparing profile data between different terminals
Inventor: RAFF ADAM
IPC: H04W4/02
Filed: 2003-01-14
Abstract: A communications system for matching information from compatible terminals in order to facilitate the matching of user interests. Possible applications include finding possible partners, searching for a retailer with a particular item in stock, searching for suitable property, etc. A plurality of user terminals 2 (which may be e.g. personal computers, PDAs, palmtops, mobile telephones) each store at least one profile, with different profile types being stored for different intended purposes. Each profile contains: attributes - personal data of the user and a set of characteristics of the user or of something offered by the user; requirements - the user's search criteria; and predetermined introduction information comprising introduction attributes and requirements. The introduction server compares introduction information with reference to one instance of an active profile, and registers two profiles as being "compatible" when the introduction requirements of one profile are satisfied by the introduction attributes of the other. A match processor, located at the terminal on whose profile the search was based or at the introduction sewer, then performs a frill profile match of the compatible profiles (again, on a one-to-many basis). The attributes are never shared between the terminals during the matching process. Methods for initiating communication between matching terminals are also described.
