Patent CA-2353453-A1 (CA)
Inventor: WALTSON J ROD
IPC: H04W92/00
Filed: 1999-12-03
Abstract: Lorsque le trafic dans le réseau est insuffisant pour maintenir la synchronisation de cette façon, d'autres méthodes doivent être mises en oeuvre. Une approche consiste à effectuer des mesures directes de la synchronisation entre des stations de base (602, 604). Pour ce faire, deux méthodes sont possibles. La base peut interrompre ses transmissions dans tous les secteurs pendant une brève durée au cours de laquelle elle détermine le moment d'arrivée de signaux provenant d'autres stations de base (602, 604). La connaissance des autres emplacements des stations de base permet de déduire des erreurs de synchronisation par rapport à toutes les stations de base (602, 604) restantes. Selon l'autre méthode, la base peut envoyer un signal bref à grande puissance dans la bande de l'émetteur mobile. L'heure d'arrivée de ce signal est mesurée par les stations de base environnantes et les erreurs de synchronisation entre des paires de stations de base sont calculées. Dans certains cas, une station de base (602, 604) peut être isolée suffisamment de toutes les autres stations de base du réseau de sorte qu'une mesure entre bases soit inopérante. Dans ce cas, une unité mobile fixe (606) est disposée à un emplacement dans la zone de transfert entre la cellule isolée et une autre cellule du réseau. L'unité mobile fixe (606) soit effectue des mesures sur des pilotes de station de base contrôlant la base et transmet les informations de synchronisation, soit envoie une transmission par rafales à un moment et à un niveau de puissance précis destinés à être mesurés par les stations de base.
Patent CA-2354178-A1 (CA)
Inventor: SATOU MASAHIRO
IPC: F02D9/02
Filed: 2001-07-26
Abstract: A controller for an internal combustion engine detects a demand variable showing a demand from a driver, and controls an intake air volume to the internal combustion engine according to the detected demand variable. When trouble is detected in a system controlling the intake air volume, the controller switches a driving control of a vehicle to a emergency driving mode. In the emergency driving mode, the controller keeps the intake air volume to the internal combustion engine constant. The controller calculates a emergency driving control variable according to the detected demand variable, and controls the driving of the vehicle according to the calculated emergency driving control variable.  The emergency driving control variable is a control variable different from the intake air volume. Thus, in the emergency driving mode, the driving of the vehicle can be controlled by the control variable different from the intake air volume, and a better drivability is ensured. -40-

Inventor: ZANKER KLAUS JOACHIM
IPC: G01F1/66
Filed: 2001-12-17
Abstract: A silencer for use with ultrasonic meters to reduce stray ultrasonic noise that could cause measurement inaccuracies. The silencer comprises a tubular body having at least two baffles spaced apart from one another. The baffles are preferably formed of an open-cell, reticulated metal foam material that absorbs noise in the ultrasonic range of frequencies under high-pressure operating conditions. The silencer is a reasonable flow conditioner and can be mounted directly to the meter without disturbing the flow. The silencer reduces the level of ultrasonic stray noise by absorption.  Ultrasonic noise waves are partially reflected between the baffles and along their length as the waves move between baffles. With each reflection, the baffle material absorbs energy that is lost by friction in the pores of the foam material. Through this process of the ultrasonic waves being reflected and the noise being incrementally absorbed, the energy of the ultrasonic wave is attenuated.

Title: Stabilization of cooked pasta compositions using whey from nisin-producing cultures
Inventor: BROOKS SCOTT
IPC: A23L7/109
Filed: 2002-01-24
Abstract: The present invention provides fully cooked, ready to heat and serve pasta compositions which are stabilized against the development of toxins from pathogenic bacterial contaminants under refrigeration conditions for 120 days or more. The stabilized pasta compositions are attained by the incorporation of nisin-containing cultured whey derived from a nisin-producing culture. The cooked pasta compositions of this invention, which include both filled and unfilled pasta compositions, are stable at refrigeration temperatures for 120 days or longer and require no further cooking (i.e., the pasta is fully hydrated and only requires warming before serving). The nisin-containing whey can be prepared by forming an aqueous composition comprising sweet whey from the fermentation of a cheese, whey protein concentrate, and a protein hydrolysate; fermenting the aqueous composition with a nisin-producing culture until the pH attains about 5.5; maintaining the pH of the fermenting composition at about 5.5 for 8-10 hrs; and allowing the pH of the fermenting composition to drop to 4.8 or lower. The nisin-containing cultured whey can also be prepared by a inoculating a pasteurized dairy composition with a culture of a nisin-producing microorganism, incubating the composition until the pH attains a value between about 6.2 and about 4.0 and a whey and curd mixture is formed, and separating the whey from the whey and curd mixture to give the separated whey which is the nisin-containing cultured whey. The pasta of the present invention is prepared from pasta dough comprising about 55 to about 80 percent high protein wheat flour, about 1 to about 5 percent wheat gluten, 0 to about 20 percent egg product, 0 to about 3 percent dough conditioner, sufficient nisin-containing cultured whey to provide about 200 to about 1200 IU nisin/g pasta dough, and sufficient water to provide a total moisture content of about 25 to about 35 percent. Sauces and/or fillings included with the pasta compositions are preferably prepared using the same or similar nisin-containing cultured whey compositions to provide increased stability.
