Title: Method and device for assessing the service quality of transmission channels in a digital transmission system
Inventor: PLECHINGER JORG
IPC: H04L1/20
Filed: 1998-07-29
Abstract: The invention relates to a method and a device for assessing the service quality of transmission channels in a digital transmission system, wherein turbo-coding for channel coding is carried out in a turbo-coder on the sender side and turbo decoding is performed using a turbo-decoder with soft decision output signals on the receiver side. Service quality is determined on the basis of variances in the soft decision output signals in the turbo-decoder. When a MAP symbol evaluator is used in the receiver side, the service quality is determined on the basis of the variances .sigma.2LLR of the soft decision output signals of the turbo-decoder. The bit error rate is calculated on the basis of the variances .sigma.2LLR to measure service quality. An RCPTC is used as turbo-code in the method and in the device.

Title: Dispositif d'interface souris et procede permettant d'ameliorer la commande du curseur
Inventor: ROSENBERG LOUIS B
IPC: G06F3/038
Filed: 1998-08-21
Abstract: L'invention concerne un dispositif d'interface à retour d'effort (14) qui est couplé à un ordinateur hôte (18) et qui comprend un objet de manipulation (12), tel qu'une souris, que l'on peut déplacer sur un espace de travail local (24). Une position du curseur (222) dans le cadre d'affichage (28) est communiquée à l'ordinateur hôte (18) par rapport à une position de référence (204) de la souris (12) dans le cadre local (30), puis l'hôte (18) affiche le curseur (180). On peut par exemple calculer la position du curseur (222) au moyen d'un algorithme de balistique (206) basé sur la vitesse de la souris, afin de permettre un positionnement précis ou un déplacement grossier du curseur (180). Un effort (216) est exercé sur la souris (12), l'effort (216) étant déterminé d'après les données de référence souris ou les données balistiques curseur, en fonction du type d'effort, de manière à réduire la distorsion entre les sorties visuelles et les sorties d'effort. Des efforts accessoires et des fonctions d'indexation permettent en outre d'améliorer la commande du curseur.

Filed: 1998-10-06
Abstract: A railway truck leveling valve arrangement for improved railway car floor height control comprises a pneumatic level regulating valve (26), a rigid, lightweight bar (14), and a leveling valve linkage (12). The level regulating valve (26) is connected to and mounted above a secondary air spring suspension (30). The rigid, lightweight bar (14) extends between the axleboxes (16) of the railway truck wheelsets (19), the railway truck wheelsets (19) being coupled to a primary suspension (28). The level regulating valve linkage (12) connects the level regulating valve (26) and the rigid bar (14). The level regulating valve (26) senses spring deflection in both primary and secondary suspensions (28, 30) and signals the secondary air spring suspension (30) to compensate for both deflections. Consequently, the correction of the overall railway car floor height by the secondary suspension provides more precise car floor to station platform height control.

Title: Novel lentiviral packaging cells
Inventor: LEBOULCH PHILIPPE
IPC: C12N15/867
Filed: 1999-05-13
Abstract: Novel packaging cell lines which produce recombinant retrovirus, free of detectable helper-virus are disclosed. Also disclosed are methods of making the cell lines and methods of producing recombinant retroviruses from the cell lines. Retroviruses produced by the cell lines include lentiviruses, such as HIV, capable of transfering heterologous DNA to a wide range of non-dividing cells. The packaging cells contain at least three vectors which collectively encode retroviral gag, pol, and env proteins, wherein the gag and pol genes are separated, in part, onto two or more different vectors. This is made possible by fusing Vpr or Vpx to pol proteins separated from gag so that the proteins are targeted to assembling virions. Among other advantages, the packaging cells provide the benefit of increased safety when used in human gene therapy by virtually eliminating the possibility of molecular recombination leading to production of replication-competant helper virus.
Patent CA-2328437-A1 (CA)
Title: Method of and apparatus for isochronous data communication
Inventor: BAKER MATTHEW P J
IPC: H04L12/70
Filed: 2000-01-24
Abstract: In order to enable isochronous data to be transmitted over communications systems which may introduce timing jitter each packet of isochronous data is provided with a timestamp which indicates to a receiver the time at which a packet should be processed. The receiver notes the time the first packet of a data stream arrives and adds a given offset time which is greater than or equal to the maximum jitter to produce a time t1. Each succeeding packet is processed at a time t- t1 +(Tn-T1), where T1 is the timestamp in the first data packet and Tn is the timestamp in the current packet. Thus the processing at the receiver is dependent on the relative times of arrival of the packets rather than the absolute times defined by the timestamps.
