Abstract: An intelligent network comprises switching units (54, 56) interconnected to provide connections between originating users (50) and terminating users (52).  The intelligent network includes a set of SCPs (60 to 70) which can be accessed by the switching units through a signalling network (58). The SCPs contain individual service profiles which define the individual services provided to users of the network as originating users and individual service profiles which define the individual services provided to the users as terminating users. During call set-up, a service control program which acts as agent for the originating user is generated from the service profile for the originating user as an originating user and a service control program which acts as agent for the terminating user is generated from the service profile for the terminating user as a terminating user. The two service control programs then enter into a dialogue with each other in order to generate call control instructions.

Title: Five beveled point geometry for a hypodermic needle
Inventor: DOYLE JUDITH L
IPC: A61M5/158
Filed: 1997-06-12
Granted: 2000-11-28
Abstract: A hypodermic needle featuring a multi-beveled point geometry is disclosed. In one embodiment, the multi-beveled point features a primary bevel, a pair of tip bevels, and a pair of middle bevels each intermediate the primary bevel and a respective one of the tip bevels. The primary and middle bevels are provided at angles of inclination, measured between the central axis and a reference plane that are substantially identical. The tip bevels are formed at an angle of inclination respective to the central axis which is not equal to the angle of inclination at which the primary and middle bevels are formed. The resulting five-beveled point geometry contributes to a more continuous bevel face free of abrupt intercepts or transitions between the respective bevel faces, lessening the penetration force required to urge the needle point through skin, flesh, or other material.

Abstract: Le système de diffusion analogue à un disque (80), selon l'invention, assure la diffusion de données sans fil selon une technique AMRT/AMF (accès multiple à répartition dans le temps/accès à multiplexage de fréquence), et est divisé en données élémentaires agencées par tranches de temps et à répétition périodique, analogues à des secteurs sur un disque rotatif, et sur plusieurs fréquences de diffusion, analogues aux pistes d'un disque. Les données élémentaires (1 - 14) sur le disque de diffusion peuvent être classifiées en fonction du domaine d'intérêt de l'utilisateur, du profil de l'utilisateur ou de sondages relatifs aux préférences de l'utilisateur, par exemple par surveillance d'une liaison montante pour des requêtes d'utilisateur. La surveillance de la liaison montante peut être effectuée avec une durée inférieure à la période de rotation du disque de diffusion. On peut empêcher que les utilisateurs ne demandent des données déjà présentes sur le disque pendant un intervalle de temps prescrit. La classification des données élémentaires peut être faite en fonction du niveau de popularité, calculé itérativement par une fonction objective qui échange des données élémentaires pondérées et classées selon un rang, sur le disque de diffusion, en vue de l'obtention de la valeur d'ordres de classification candidats qui optimisent la fonction objective.

Abstract: There is provided a new and useful device for use in a centrifugal clutch assembly in which the clutch assembly comprises a shaft which carries a first sheave axially moveable on the shaft and a second sheave axially fixed on the shaft, a drive belt between the first sheave and the second sheave and a return spring operating on the first sheave. A roller is fixed relative to the first sheave and a pivot pin is fixed on and moveable with the first sheave. The device further comprises a body having an arcuate outer surface constructed so as to provide a cam surface relative to the roller. An aperture is provided in the body and is constructed so as to mate with the pivot pin to allow the device to pivot relative to the pivot pin. A hollow chamber is positioned internally within the body and moveable weighting means are positioned within the chamber. In use, the first sheave rotates at a variable speed, so as to generate a centrifugal force upon the device whereupon at a predetermined engagement speed, the device pivots from a rest position to a full engagement position thereby transferring a force to the first sheave to axially move the first sheave into engagement with the second sheave to transfer rotation from the first sheave to the second sheave.

Abstract: A motion estimation and compensation technique is provided for interlaced digital video such as video object planes (VOPs). Predictor motion vectors for use in differentially encoding a current field coded macroblock (700) are obtained using the median of motion vectors (MV1, MV2, MV3) of surrounding blocks or macroblocks (712, 722, 732). When a surrounding macroblock (820) is itself interlaced coded, an average motion vector for that macroblock is used, with fractional pixel values being mapped to the half-pixel. When the current block (912) is not interlaced coded but a surrounding block (820) is, the field motion vectors may be used individually or averaged.   In a repetitive padding technique for an interlaced coded VOP (1,010), the even (0, 2, ..., 14) and odd (1, 3, ..., 15) lines of the VOP and surrounding block (1,000) are grouped.  Within each field (1,210, 1,220), exterior pixels (1,6) are padded by setting them to the value of the nearest boundary pixel (0,6), or to an average of two boundary pixels (0,6; 1,7).  The lines are then reordered to provide a single padded reference VOP image.
