Title: Intercalador de código turbo utilizando sequências lineares congruentes
Inventor: ROWITCH DOUGLAS N
IPC: H03M13/27
Filed: 1999-12-03
Abstract: Patente de Invenção: "INTERCALADOR DE CóDIGO TURBO UTILIZANDO SEQUêNCIAS LINEARES CONGRUENTES". Um intercalador de código turbo (100) utilizando seq³ências congruentes lineares pode ser empregado como um intercalador bidimensional (16) em um turbo codificador (10) que inclui também primeiro e segundo codificadores constituintes (12, 14). O intercalador (16) e o primeiro codificador (12) estão, cada um, configurados para receber bits de alimentação. O primeiro codificador (12) produz símbolos de saída (22, 24) a partir dos mesmos. O intercalador (16) recebe os bits de alimentação (20) seq³encialmente por fileira. Um algoritmo recursivo de seq³ência linear congruente no interior do intercalador (16) serve para rearranjar, ou embaralhar, pseudo aleatoriamente os bits no interior de cada fileira do intercalador (16). Os bits (26) são a seguir emitidos a partir do intercalador seq³encialmente por coluna. O segundo codificador (14) está configurado para receber os bits intercalados provenientes do intercalador. O segundo codificador (14) produz símbolos de saída (28) a partir dos mesmos. As duas correntes de símbolos emitidos (22, 24) são multiplicadas, com o puncionamento (punching) adequado. Caso desejado, a seq³ência recursiva congruente linear pode ser gerada em reverso. Além disso, caso desejado, uma técnica de inversão de bits pode ser usada no intercalador (16) para rearranjar, ou embaralhar, as fileiras do intercalador (16).

Title: Inhibiting fraudulent transactions
Inventor: WARD JOHN
IPC: G07F19/00
Filed: 2000-05-23
Abstract: Fraudulent transactions are inhibited by using a personal parameter of the transactor as verification, or otherwise, of identity as the authorised person to sign a cheque or to use a bank or credit card. When the transaction involves the use of a cash-dispensing machine 30, the identity of the person wishing to withdraw money is established by insertion of a forefinger in a scanner 40 that sends a corresponding signal along a transmission line 41 to a comparator 38 which also receives a signal along a transmission line 37 from a card inserted in a slot 35. The comparator 38 compares the identity of the person wishing to withdraw money with the pre-recorded identity of the authorised card holder held in a data base 39. If the identities do not match, a signal is sent along transmission line 42 to prevent cash being dispensed through slot 34 or otherwise to terminate the transaction. The data base 39 also includes the identities of known fraudsters. The details of each attempted fraud are stored in the data base. The comparator 38 is additionally able to send a signal along a transmission line 43 to operate a light showing that the transacation has been aborted and/or a video camera 40 to record a picture of the person illegally using the cash dispenser.

Patent GB-2365156-A (GB)
Title: Generating coordination messages for use in distributed test scripts
Inventor: BAKER DOMINIC PAUL
IPC: G06F11/36
Filed: 2000-07-24
Abstract: A set of coordination messages are generated from a system specification for use in distributed test scripts in order to synchronise the testing of parallel components. In use events not relevant to the system under test are removed and the resultant system specification pre-processed. Each event is examined to see if it forms an initial event of a program path through the system. The coordinating messages are determined by making a copy of the specification, listing the initial events and adding coordinating messages to force each event to occur prior to the other events in the list to produce a sub specification. The same listing technique is reapplied to the sub-specification using the list with the original event removed to produce further sub specifications. An "after join" step is then applied to determine the feasibility of adding a coordinating message to force the event to occur before the others in the list. The coordinating messages determined by this process are then implemented as a set of distributed tests for which a verdict is determined. Preferably each test will correspond to the sub-specifications produced by the method. A further test may also be applied to ensure that the test produced is data race free.

Title: Surface passivation of organic polymers and elastomers
Inventor: SIGRIST HANS
IPC: C08J7/12
Filed: 2001-01-16
Abstract: Surface treatment of organic polymers (e.g PDMS) with oligo- or polysaccharide (e.g. aminodextran or chitosan) as passivation agent for deliberate alteration of the sorption properties, the diffusion barrier function, lubricative wetting and/or biocompatibility of organic polymers. The passivating agent is derivatized with chemical entities that allow tight adsorption and/or covalent binding of the passivating agent to organic polymers or elastomer surfaces. The passivating agent may be derivatized with a primary functional group to allow covalent surface passivation by photo- or thermal activation of the derivative. The passivating agent may comprise one or more secondary functional groups that allow covalent binding of probe molecules and receptors to the passivated surface. The surface treatment improves the biocompatability of medical devices and the performance of bioanalytical systems. Its application for heterogeneous affinity based assays, biosensor analysis platforms, microcontact printing, and lubrication of medical devices is described. Devices comprising surface passivated PDMS organic polymer are also described.

Patent GB-2357515-A (GB)
Title: Displays
Inventor: HAJTO JANOS
IPC: F21V8/00
Filed: 1999-07-29
Abstract: The present invention describes a fluorescent dye doped polymer based optical wave-guide structure. The described polymers can be used to fabricate a range of display elements and illumination systems which work without the use of external electrical power. This is due to the process of the fluorescent dyes absorbing ambient light and then subsequently emitting light which is conducted by the polymer host material to a point where it is emitted. The emitted light can be of a range of colours depending upon the type of dye that polymers are doped with. There is a constant contrast between the light power flux emitted for the wave-guide structure and the light power flux of the ambient light. There is also provided a method in which a dielectric stack mirror layer fabricated on the surface of the polymer which can be used to improve the efficiency and the contrast of those optical elements.
