Patent CA-2352644-A1 (CA)
Inventor: HUNT ANDREW WILLIAM
IPC: H03M13/37
Filed: 2001-07-06
Abstract: A class of codes and associated methods and devices are provided. Advantageously, such codes when used as constituent codes in composite codes intended for iterative decoding, as compared to the standard practice of using convolutional codes, may allow better error-correcting performance to be achieved, especially at low error rates and high code rates, for a given decoder complexity. State sequencing in these codes is driven not by source data alone, as is the case with convolutional codes, but rather by a sequence that includes both the source data and so-called "inserted" data elements, the inserted data elements having a linear dependence on the state sequencing state. In decoding, state transition intervals involving one or more inserted data elements are handled in a special way.

Title: Hydrocarbon reservoir testing
Inventor: ROBINSON JAMES
IPC: G06T17/20
Filed: 1999-12-15
Abstract: A reservoir in a payrock (2) is analysed using finite element simulation. A reservoir engineer selects an appropriate model from a set of template model s, each comprising a set of polygons (51) in plan and layers (53) in elevation.  The polygons are defined in objects instantiated from classes by control points and the layers as depth values of control points. A pattern object sweeps rotationally about a wellbore in a wellbore polygon to define a patte rn of elements, fewer in number with distance from the wellbore. A polygon obje ct also sweeps linearly from a generator line in the direction of a base line. The generator and a base lines correspond to polygon boundaries. Finite element simulation is performed with the model so derived.

IPC: F41H13/00
Filed: 2001-08-24
Abstract: Training, maintaining proficiency and certifying people in techniques for using non-deadly force in a way that minimizes the chance of bodily injury to an individual being subdued comprises teaching a number of techniques to trainees, wherein the techniques involve applying tactile pressure to nerve locations while applying leverage to the body of an individual in order to subdue the individual. The trainees are then certified as having learned the techniques and are qualified as practitioners of the techniques. The practitioners are recertified periodically in order to maintain proficiency. Since the techniques are non-deadly and minimize risk of bodily injury; police officers, security personnel and their employers are far less likely to be sued if the techniques are employed, which of course lessen the likelihood that excessive force will be used, with all of its unfortunate implications.

Abstract: L'invention concerne un récipient auto-chauffant (10) pourvu d'une cavité interne (22) destinée à son contenu et d'une cavité externe (20) destinée à un système de chauffe, constitué par exemple de première et seconde matières réagissant chimiquement qui sont disposées pour être mélangées, quand on veut déclencher le système de chauffe. Un dispositif de fermeture (30) ferme la cavité externe (20). Lorsqu'on actionne le système de chauffe pour mélanger les produits chimiques, on provoque une réaction exothermique, de la vapeur, telle que de la buée ou de l'air chaud est produit. Le dispositif de fermeture (30) comporte une bride d'étanchéité annulaire (100) qui met en contact un rebord annulaire (102) du récipient. Ladite bride (100) crée un joint étanche avec la cavité externe vis-à-vis de l'air environnant et maintient la réactivité des produits chimiques à l'intérieur de ladite cavité. Toutefois, la bride d'étanchéité (100) est enlevée du rebord (102), lorsque la génération de vapeur fait augmenter la pression dans la cavité externe (20), la vapeur est alors éventée dans l'atmosphère.

Abstract: In this lift equipment a lift cage (2) is on the way down, wherein a halt at the bottom storey is scheduled. If the lift cage (2) does not halt at the bottom storey according to plan, the lift cage (2) in its further travel is caught by buffers (26). In that case a safety brake (16) can be tripped due to the inertia of a speed limiter (13) and a limiter cable (19). So that the undesired tripping of the safety brake (16) can be avoided in the case of buffer travel, there is provided in the lift shaft (1) a blocking element (27) which blocks the movement of a blocking lever (25) as soon as the lift cage (2) has gone down past the bottom storey. The blocked blocking lever (25) blocks one double lever (14) and, by way of a linkage (18), the other double lever (14). Tripping of the safety brake (16) is thus precluded.
