Title: Liaison de donnees integrees et protocole associe

Abstract: Liaison de données pour appareil de stimulation tissulaire sous-cutané, et protocole associé. Durant la stimulation, sous le contrôle d'impulsions dont la durée à l'intérieur d'une trame de données détermine la largeur des impulsions de stimulation, les données sont en fait émises et traitées de façon à déterminer les paramètres de la stimulation suivante. L'émission des données se fait simultanément à la stimulation. Les données sont représentées par des séquences comportant plus de 1 que de 0, chaque 1 étant représenté par plusieurs cycles R.F. successifs et un 0 seul par l'absence de plusieurs cycles R.F. Ceci permet d'obtenir un cycle opératoire de 75 %, capable de transférer à l'implant l'énergie nécessaire. Les variations des conditions de la liaison, par exemple du degré de résonance, sont compensées par le réglage du décalage des bobines émettrices et réceptrices transcutanées. De ce fait, le signal oscillant qui persiste dans le circuit récepteur durant la transmission d'un 0 est déphasé par rapport à l'émission R.F. reçue pour le 1 suivant. Dans la bobine réceptrice, le signal induit par l'émission d'un nouveau 1 annule la résonance déphasée due à l'émission antérieure, ce qui fait tomber l'amplitude de l'oscillation en-dessous d'un niveau de détection et assure la détection d'un 0 émis antérieurement pendant l'émission du 1 suivant. Un décodeur binaire recueille de manière non équivoque le nombre de 1 pour une plage spécifiée de conditions de la liaison. L'invention concerne également un système d'émission qui utilise des trames de longueur variable représentant à la fois les données numériques et les informations d'intervalle de temps, et un système d'émission dans lequel chaque trame comporte à la fois des informations de commande analogiques et des informations de commande numériques pour les circuits d'utilisation choisis.

Granted: 2000-09-12
Abstract: A means of connecting a plurality of essentially identical active devices (Q1, Q2, Q3, Q4) is presented for the purpose of multifunction and multiple function operation. These devices (Q1, Q2, Q3, Q4), mounted on a chip (66), are flip-mounted to a circuit motherboard having large passive elements. A  push-pull amplifier (50) is presented as an example in which the multiple function operation is the combining of amplifiers (56, 58) whose active devices (Q1, Q2, Q3, Q4) are on a single chip (66). The electromagnetic coupling, impedance matching and signal transmission are variously provided by the use of striplines (82, 88), slotlines (94, 100), coplanar waveguides (116, 130), and a slotline (180) converted into a coplanar waveguide (176, 178). In particular, a conversion of a split coplanar slotline (170) to dual coplanar waveguides (176, 178) provides signal transmission to a pair of transistors (166) flip-mounted onto the coplanar waveguides (176, 178).

Title: Process for analysing traffic location in a cellular radio communication network
Inventor: HO-A-CHUCK OLIVIER
IPC: H04W16/18
Filed: 1997-04-15
Granted: 2004-06-22
Abstract: In order to analyse the location of the traffic of a base station in a cellular radio communications network, the process uses measurements of radio parameters made by mobile stations in respect of the said base station and neighbouring base stations. Statistical processing of these measurements, together with cartographic data on the prameters measured, make it possible to determine traffic density in the cell, at least in areas of high traffic density. These results enable the operator of the network to choose the best locations for the installation of new base stations, including microcells.

Title: Process for producing milk infused cereal grain ready-to-eat products
Inventor: ZUKERMAN RACHEL B
IPC: A23L1/164
Filed: 1999-10-20
Granted: 2002-05-14
Abstract: RTE, dry, puffed cereal pieces and refrigerated fluid-milk have traditionally been consumed from a bowl with a spoon. They cannot be picked up and consumed hand-held because the RTE, dry, puffed cereal pieces absorb the fluid-milk and become soggy. In addition there always remains an excess amount of fluid milk in the bowl because the RTE, dry, puffed cereal pieces have a very small and limited fluid-milk absorption capacity. The present invention relates to a process for producing a ready-to-eat cereal and fluid-milk breakfast food product having a firm surface and an interior comprised of fully cooked, soft and moist, fluid-milk-infused cereal grains joined together. The cereal and fluid-milk products of the present invention can be picked up and eaten hand-held because their textures do not become soggy even when the cereal grains have been infused with all the added fluid-milk. In the process of the present invention, 200 to 400 lbs. of a fluid-milk solution which contains starch complexing agents, flavors and sweeteners, are infused into each 100 lbs. of cereal grains at temperatures above 180 F until the cereal grains become infused with all the fluid-milk solution, fully cooked, and soft and moist in texture. The proteins of the cooked fluid-milk together with the gelatinized starch of the cooked cereal grains provide the needed fluid-binding and cohesive properties which synergistically act together to both cause the individual fully-cooked cereal grains to become joined to one another and in addition, to bind and retain all the infused fluid-milk solution within the cereal grains' interiors. The fluid-milk-infused cereal grains are then shaped into units with low shear forming equipment, and oven-baked to firm their surface texture and develop their golden brown surface color while still retaining their soft, moist, fluid-milk-infused interior texture.
