Patent CA-2342139-A1 (CA)
Inventor: DALRYMPLE LARRY VERL
IPC: E21B47/10
Filed: 1999-08-25
Abstract: L'invention concerne un câble chauffant (10) déroulable dans un puits de forage utilisé pour y augmenter la température de façon que la température du puits de forage soit supérieure à celle du liquide environnant et à celle de la formation. Le câble chauffant qui comporte et achemine au moins un fil à fibres optiques, est placé sur toute la longueur voulue du puits de forage. Au moins un fil à fibres optiques mesure la température du câble chauffant à plusieurs emplacements distincts. On peut utiliser un autre fil pour déterminer la température du puits de forage. Dans un mode de réalisation de cette invention, le câble chauffant est chauffé à une température supérieure à celle du puits de forage. Le liquide, qui s'écoule de la formation vers le puits de forage, diminue la température du câble aux emplacements d'entrée. Le fil à fibres optiques permet d'obtenir des mesures de la température le long du câble chauffant. On détermine le débit du liquide à partir du profil des températures du câble chauffant, généré par les capteurs à fibres optiques.
Patent CA-2342409-A1 (CA)
Inventor: TAI KING LIEN
IPC: B81B7/00
Filed: 2001-03-29
Abstract: The specification describes packaging assemblies for micro-electronic machined mechanical systems (MEMS). The MEMS devices in these package assemblies are based on silicon MEMS devices on a silicon support and the MEMS devices and the silicon support are mechanically isolated from foreign materials. Foreign materials pose the potential for differential thermal expansion that deleteriously affects optical alignment in the MEMS devices. In a preferred embodiment the MEMS devices are enclosed in an all-silicon chamber. Mechanical isolation is also aided by using a pin contact array for interconnecting the silicon support substrate for the MEMS devices to the next interconnect level. The use of the pin contact array also allows the MEMS  devices to be easily demountable for replacement or repair.

Title: Forward link transmission power control during soft handoff
Inventor: BENDER PAUL E
IPC: H04B7/02
Filed: 2000-05-25
Abstract: Forward power control for a mobile communication system is provided on a frame by frame basis during a soft handoff of a mobile station from a source base station to a target base station. Each base station runs independent but identical algorithms. A selector runs the same power control algorithm as each base station and coordinates power control between the two base stations and the mobile station during the soft handoff. The results of the algorithm run by the selector are delayed because of backhaul. The selector provides the base stations with traffic gain and frame delay information corresponding to the traffic gain. The base station ASIC, modifies the base station power output according to the SNR data received from the mobile station and the traffic gain and frame delay information received from the selector. Providing the frame delay information permits forward power control even when there is delay from when the selector computes the traffic gain and the traffic gain is programmed into the base station application specific integrated circuit.

Abstract: The present invention proposes a transmission method for transmission of data in a telecommunication network, said network comprising a core network (CN) and an  access network (AN), with said access network (AN) comprising at least one access system (RAN; BSS) of a GSM based access system type; wherein data are transmitted between said core network (CN) and said at least one access system (BSS) of a GSM based access system type of said access network (AN) via an Iu interface (Iu-I/F). Also, the present invention aims to provide accordingly adapted network elements. By virtue of the present invention, substantial savings concerning resources can be obtained by supporting data formats of GSM coded speech on the open, i.e. not network operator proprietary, Iu interface according to UMTS/3rd generation specification.      Thus, GSM transcoders and 3rd generation transcoders as well as GSM base station controllers and 3rd generation radio network controllers can be integrated, so that the same hardware resources can be used for both systems, i.e. for GSM as well as for~ 3rd generation.

Abstract: L'invention concerne un procédé de préparation de riz absorbeur d'eau permettant une absorption d'eau rapide et uniforme par le riz qui n'a pas été complètement gélatinisé. Après son immersion dans l'eau, le riz est introduit dans une solution aqueuse et soumis à un chauffage par agitation, les grains de riz individuels étant amenés à circuler en "sautillant" vers le haut et vers le bas. Ensuite, le riz est placé dans un récipient éventuellement étanche à l'air conjointement avec la solution aqueuse, puis recouvert ou enfermé (dans le cas d'un récipient étanche à l'air) avant d'être refroidi. En chauffant le riz absorbeur d'eau ainsi préparé dans un four à micro-ondes, par exemple, on obtient un riz uniforme présentant une odeur de riz fraîchement cuit et ne comprenant aucune masse solide.
