Abstract: An advanced telecommunication system is provided for central control of electronic signs (32). A display development kit is provided to create binary display programs which create visual activity on one or more electronic signs. These display programs are stored on the disk drive (18) of a system control computer (16) which periodically runs a system control program to upload display programs to the electronic signs using radiopaging signals. The system control program employs a telephone modem (20) to connect through a public switched telephone network (PSTN) (26) to a paging terminal (22). In accordance with the system control program, the system control computer divides each display program into multiple packets which are transmitted to the paging terminal as alphanumeric radiopages. The paging terminal encodes the packets into radiopaging format, frequency shift key modulates the data, and transmits the pages on a radio frequency channel.  Electronic signs (32) decode the radiopages into data packets. A receiver subsystem (34) in the electronic sign reconstructs the original display programs using the data packets. Data provided in a display program can span across more than one page. The system control program creates packets containing display program data such that blocks of display program data that are greater than one page are transmitted transparently to a paging terminal from the central computer, and from the paging terminal to a paging receiver without requiring hardward or sof-tware modification of existing paging terminals and paging central offices.

Abstract: In a hook structure for a molded surface fastener, in an arbitrary cross section of each of a stem and a hook-shape engaging portion of a hook, the cross-sectional area is divided into front and rear side cross-sectional areas with respect to the center line of the hook, and the front side cross-sectional area is defined to be larger than the rear side cross-sectional area.  Therefore, the neutral plane of the hook is shifted toward the front side of the stem and the inner side of the hook-shape engaging portion to a further extent than conventional to reduce possible tensile stresses in the front part of the stem and the inner part of the hook-shape engaging portion so that, as compared to the conventional hook made of the same resin quantity and having a substantially similar shape, the strength of the hook is increased sharply and, necessarily, both the front part of the stem and the inner part of the hook-shape engaging portion is increased in rigidity as compared to the other part and hence is difficult to deform, thus causing an increased strength as well as an increased engaging strength with a loop of a companion surface fastener.

Title: Detecteur de mouvement a grand angle comprenant un reflecteur a courte distance
Inventor: SANDELL DONALD R
IPC: G01V8/10
Filed: 1994-10-04
Granted: 1999-09-07
Abstract: L'invention concerne un détecteur de mouvement à infrarouges passif, avec un large champ de vision pouvant s'étendre jusqu'à plus de 180 degrés. Ce détecteur peut être obtenu, à moindres coûts, en utilisant un seul capteur. Ce détecteur comprend un capteur à infrarouges plan (12, 46) et deux faces de réflexion à infrarouges (16, 17 et 41, 42) ou davantage qui sont positionnées près d'une partie du capteur et recouvrent au moins une partie de ce dernier. Les faces de réflexion sont configurées de telle sorte que leurs extrémités proches du capteur recouvrent ce dernier au niveau de sa partie médiane. Ces faces s'étendent depuis la partie médiane dans différentes directions, à l'opposé l'une de l'autre, pour réfléchir les rayonnements vers le capteur à partir des différents côtés de ce dernier. Dans une forme de réalisation, les faces de réflexion (16, 17) ont généralement la forme d'un prisme (11). Dans une autre forme de réalisation, les extrémités proximales (43, 44) d'une paire de faces (41, 42) sont déplacées sur le capteur dans le sens latéral, l'une par rapport à l'autre, de telle sorte que les faces recouvrant le capteur obstruent une partie (51, 53) de ce dernier et laissent une partie (52, 54) non obstruée. Cela forme un motif en échiquier de zones obstruées et non obstruées. Les faces de réflexion sont positionnées à proximité du capteur, leurs extrémités proximales étant espacées de ce dernier, au maximum, selon une distance comparable à une dimension transversale caractéristique du capteur. Etant donné que le miroir est placé à proximité du capteur, il n'est pas nécessaire que la surface des faces de réflexion soit très grande et elle peut être même relativement petite. Les surfaces du miroir défléchissent une énergie infrarouge à partir d'un moyen de focalisation approprié (13) sur le capteur à partir d'une pluralité de zones, de manière à étendre les extrémité latérale du champ de vision du détecteur de mouvement. Avec cette configuration, les détecteurs de mouvement peuvent être pourvus d'angles de vision pouvant atteindre jusqu'à 220 degrés, en utilisant un seul capteur. Les faces de réflexion peuvent comporter une base formée à partir d'un seul élément (31, 61) dont la forme est également adaptée pour recevoir et supporter un ensemble de capteurs à circuits intégrés (22). La tête de réflexion et la partie formant base qui constituent un seul élément peuvent être fixées directement sur une plaquette de circuits imprimés (34) et les faces de réflexion sont automatiquement alignées correctement sur le capteur.

Abstract: Un modèle de simulation du comportement d'un gisement souterrain est défin i à partir de la connaissance géologique initiale et des données disponibles. Il permet de faire des prévisions de production à partir de paramètres représentatifs des données initiales. - La méthode consiste essentiellement à définir un ou plusieurs scénarios possibles d'évolution de la production en créant, pour chacun de ces scénarios, des données nouvelles de production correspondant à des hypothèses sur les états futurs du gisement. On cherche alors, pour chaque scénario envisagé, s'il est possible d'ajuster les paramètres disponibles du modèle de simulation, compte-tenu des contraintes du modèles géologique initial, pour que le modèle de simulation restitue à la fois les données de productions mesurées et les données rajoutées. La méthode peut être utilisée pour quantifier les incertitudes sur les prévisio ns de production en recherchant les extrêmes min/max des valeurs futures de la production. - Application à la production d'hydrocarbures par exemple.

Abstract: An automatic beverage brewing apparatus including a brew chamber assembly with a throat in a top portion, a drain in a bottom portion, and a filter positioned therebetween.  A movable piston controllably opens and closes the throat and drain during brewing and flushing cycles.  A discharge line from the brew chamber has a controllable discharge valve to direct flow from the brew chamber through a dispensing line, a waste line, or to prevent flow through either line.  Water may be controllably accumulated in the brew chamber by controlling the discharge valve to prevent flow through either line.  At the initiation of the brewing cycle the valve is operated to block the dispensing line and the waste line, whereupon a brewing substance and brewing water are introduced into the brew chamber.  The brewing substance floats on and steeps in the brewing water which is accumulated in the brew chamber.  A pressurized water line dispenses water into the throat to rinse the throat.  After the brewing cycle is complete, a flushing cycle begins to thoroughly flush the spent brewing substance from the brew chamber.  The discharge valve blocks the discharge line to retain water in the brew chamber to float the spent brewing substance off of the filter.    Upon floating the brewing substance, the drain is opened to remove the float water and substance.

Abstract: Prior to completing a telephone call, a database is accessed within a telecommunications network to determine whether the call should be completed. The billing number to which the call is to be charged is compared to a customer record assigned to the billing number and stored in the database.          The customer record is checked against a treatment category code which combines geographic call restrictions and thresholding. A call may be identified as potentially fraudulent and blocked if the customer record associated with the billing number indicates that the account is in arrears. In addition, at predetermined intervals during the progress of the call and at the end of each allowed call to be charged to that billing number, the time and/or cost of each call is estimated and added to the total stored in a user-defied threshold counter in the database. When the total stored in the counter exceeds a predetermined threshold limit, a potentially fraudulent call is identified. In this manner, call authorization is performed on a per call basis to prevent fraudulent telephone calls

Abstract: In prior art three-phase electric machines with a layered winding, the conductor elements either make non-optimum use of the space in the slot or the conductors for each phase are in the form of large elements designed to be fitted into each other and whose manufacture is complicated and costly.  The invention calls for the conductors (5-7) for each phase in the three-phase conductor layer (11) to be identical in construction and for the construction to be repeated every four pole pitches.  While the phase conductors (5-7) occupy the full height of the layer within the magnetic field, two phase conductors (5-7) superposed one above the other in the slot share the space at the coil ends (9).  At the slot exit, the conductor cross-section increases and only later, at the coil end (9), halved from only one side at each passage through the coil end.  In order to alternate the layer halves, contact surfaces are available which are large in comparison to the conductor cross-section and the two winding ends (9) are uniformly utilized by virtue of the plaiting of the layers.  The production of three-phase conductor layers by laying alternate conducting and insulating layers is particularly suitable for small electromagnetic machines, giving uniform space utilization and hence high effectiveness and a high power density at low cost, and requiring only a few operations.
