Patent CA-2174767-A1 (CA)
Title: Improvements in and relating to carrier particles for use in dry powder inhalers
Inventor: STANIFORTH JOHN NICHOLAS
IPC: A61K9/72
Filed: 1994-10-26
Abstract: In a method of producing particles suitable for use as carrier particles in dry powder inhalers, particles (1) of a size suitable for use as carrier particles in dry powder inhalers are treated so as to dislodge small grains from the surface of the particles, without substantially changing the size of the particles during the treatment. The treatment gives improved efficiency of redispersion of active particles from the surfaces of carrier particles.
Patent CA-2174782-A1 (CA)
Inventor: GAUTHIER ANDRE
IPC: B62D33/06
Filed: 1996-04-23
Abstract: Dans le domaine du transport de bois en longueur on sait que l'emploi d'un protège cabine est une structure de prévention indispensable pour offrir au conducteur d'un camion une certaine protection en cas d'accident. Actuellement on sait que la conception du protège cabine est faite soit entièrement en acier ou entièrement en aluminium. L'inconvénient d'un protège cabine entièrement en acier est que celui-ci est trop lourd et que celui-ci rouille prématurément. Dans le cas d'un protège cabine entièrement en aluminium les parties soudées ont tendance à se rompre trop facilement ce qui rend le protège cabine insuffisamment sécuritaire. Dans la présente invention le protège cabine en aluminium est muni d'une structure en acier laquelle est recouverte d'un enduit caoutchouté qui la protège de la rouille. La structure en acier est fixée aux montants du protège cabine en aluminium au moyen de vis et de boulons. Cette structure en acier permet au protège cabine d'aluminium de résister adéquatement aux impacts causé par le déplacement de la charge de bois en longueur sur celui-ci lors d'un accident.

Abstract: Selon une forme d'exécution de la présente invention, un dispositif de commande à domicile reçoit des signaux d'un système de télévision par câble et utilise un démodulateur de câble accordé à la fréquence RF du canal qui transporte les informations/données. Le démodulateur du câble démodule les signaux RF codés en forme numérique, dans une bande de base usuelle, et ces signaux numériques sont transmis vers un récepteur de paquets qui décode les paquets adressés à des utilisateurs individuels. Lorsqu'un paquet est adressé à l'utilisateur, le récepteur de paquets transmet les données correspondantes, par exemple par un émetteur-récepteur ETHERNET, vers l'ordinateur personnel de l'utilisateur. On peut utiliser un dispositif de commande des communications pour assurer l'interface entre l'ordinateur personnel et le démodulateur du câble, ce qui permet à l'ordinateur personnel de choisir le canal auquel le démodulateur du câble est accordé, pour permettre l'utilisation de canaux de données multiples.
Patent CA-2186452-A1 (CA)
Title: A method and apparatus for processing batteries
Inventor: YOUNG MALCOLM
IPC: G01R31/36
Filed: 1995-03-28
Abstract: A method and apparatus for processing rechargeable batteries are disclosed including using processor means (100) arranged to monitor the voltage of a battery when it is being discharged and to terminate the discharge after detecting that the rate of change of the voltage has passed through a termination pattern indicative of exhaustion of a cell of the battery.  The determination is made by monitoring the voltage during discharge and detecting when the voltage curve thereof exhibits first convexity followed concavity.  The degree of convexity (3) and concavity (4), and the time interval within which they must occur, are determined by the processor means.  The discharge is also terminated if the voltage reaches a predetermined voltage or if, after the termination pattern is detected, and before the voltage has reached said predetermined voltage, a predetermined amount of charge is removed from the battery.  The invention also envisages recharging the battery first at high rate until the amount of charge returned to the battery is no more than the charge removed from the battery before the discharge was terminated.  The charge may then be continued at a lower rate until the battery is overcharged to a predetermined extent.

Inventor: GRAYER WILLIAM
IPC: B60L50/16
Filed: 1995-05-15
Abstract: In a shared processor control system for a power train of a hybrid electric vehicle operating responsive to operation of an accelerator pedal (7) and a brake pedal (8) and including a gas turbine (1b) powering a first motor-generator (1c), a flywheel (2b) powering a second motor-generator (2a), and a traction third motor-generator (3) operatively coupled for selectively driving and being driven by vehicle wheels (11), each of the first, the second and the third motor-generators being commonly connected to a high voltage bus (12) via respective rectifier-inverters (6) controlled by a single controller. The control system is operated by a method including steps for operating the accelerating pedal (7) to produce a substantially instantaneous increase in output torque with an increase in the bus (12) by the traction motor (3) to thereby produce a voltage drop, initiating increased power output from the flywheel motor-generator (2a) in response to the voltage drop to hold up the bus voltage, thereby decreasing flywheel shaft speed, and subsequently producing a proportional increase in the speed of the gas turbine (1b) in response to the decreasing shaft speed to thereby cause an increase flow of fuel to the gas turbine (1b) so as to permit an increase in voltage provided by the first motor-generator (1c). A method for providing compressive braking is also described.

Patent CA-2200135-A1 (CA)
Title: Multipriority data flow control techniques
Inventor: CHONG SONG
IPC: H04L12/56
Filed: 1997-03-17
Abstract: Methods for controlling multipriority data flow in a communications systems having a switch fabric and one or more port cards. Each port card has, or is coupled to, a buffer. The buffer is adapted for coupling to, or is integrated into, the switch fabric. Multipriority data refers to a plurality of data types, wherein each data type is assigned a priority ranking relative to other data types. A first method monitors the occupancy of a buffer. If the occupancy exceeds a second threshold, transmission of a group of second-priority bit streams is disabled until the occupancy drops below a first threshold. If the occupancy exceeds a fourth threshold, transmission of a group of first-priority bit streams is disabled until the occupancy drops below a third threshold. A second method differs from the first method in that control is applied to, and removed from, all bit streams of a given priority level, not just a group of bit streams at this priority level, if the occupancy crosses the previously-described thresholds. A third method is a combination of the first and second methods. To start, the first method is performed. Once the occupancy exceeds a fifth threshold greater than the fourth threshold, performance of the first method ceases and performance of the second method commences.

Patent CA-2201460-A1 (CA)
Title: Joint detector for multiple coded digital signals
Inventor: MOHER MICHAEL L
IPC: H03M13/00
Filed: 1997-04-01
Abstract: A method for the joint detection of multiple coded digital signals that share the same transmission medium in a manner that causes mutual interference. The method is comprised of two steps that are applied to preliminary estimates of each digital signal, one or more times. The first step is to obtain reliability estimates for each data element of each digital signal by combining the preliminary estimates, a statistical model for the interference, and any a priori information regarding the data elements. The second step is to revise these reliability estimates for each digital signal based on the forward error correction code used for that digital signal. When the steps are repeated, the revised reliability estimates from the second step are used as a priori information for the first step.
