Patent CA-2141016-A1 (CA)
Inventor: OLSON OTIS J
IPC: G01M17/00
Filed: 1995-01-24
Abstract: A vehicle clutch engagement position is disclosed wherein the clutch is moved, under computer control, at a constant rate, from a disengaged position toward a fully engaged position while the transmission is in neutral gear, and the position of the clutch is detected at first and second times (T1 and T2).  Time T1 corresponds to the time when the detected speed of the transmission input shaft is just above the dropout speed of the input shaft speed sensor.  Time T2 corresponds to the time when the detected speed of the input shaft is close to engine speed.  The position of the clutch corresponding to the incipient torque point is extrapolated by subtracting an offset amount from the position detected at time T1.  The offset is equal to the change in position from T1 to T2 multiplied by the square root of the ratio of the input shaft speeds at T1 and T2.

Patent CA-2160167-A1 (CA)
Inventor: TREMBLAY GERARD
IPC: G11C19/30
Filed: 1995-10-10
Abstract: Dans les procédés courants d'emmagasinage de l'information, les données à conserver sont inscrites en des points précis d'un substrat quelconque, pour être ensuite lues ou modifiées à l'aide d'un mécanisme de lecture écriture, ce qui demande la plupart du temps un déplacement du substrat ou médium qui supporte l'information, ou le déplacement de têtes de lecture-écriture, et souvent même les deux, comme dans le cas des lecteurs de disques. Il s'en suit un ralentissement du temps d'accès dans tous les mécanismes ou le matériel implique l'inertie de pièces mobiles, et une limitation de capacité, lorsqu'on considère les puces à mémoire, étant donné la grande prolifération de circuits électroniques nécessaires pour le stockage. Le facteur commun de tous les mécanismes actuels de stockage de l'information étant d'être statique, puisqu'ils contingentent l'information en un lieu fixe du substrat ou de la matière de référence et qu'ils nécessitent la mise en oeuvre d'un mécanisme quelconque pour chercher l'information où elle se trouve. Dans le procédé présenté ici, l'information circule d'un point de départ "A" à un point d'arrivé "B" en passant dans un canal conducteur (par exemple un câble électrique ou optique) pour revenir sans cesse à son point de départ via une unité spéciale de lecture-écriture, accompagnée d'autres mécanismes de traitement, filtrage et correction d'erreurs si nécessaire. L'information est toujours en mouvement et toujours disponible pour être lue ou modifiée (ce qui caractérise ce procédé de tous les autres qui ont cours actuellement). Elle est en quelque sorte vivante, ce qui se traduit par un excellent temps d'accès (puisqu'il n'y a pas de pièces mobiles) et une capacité de stockage importante (parce que l'extension de la capacité de stockage est fonction de la longueur des canaux et de leur nombre, plutôt que de la multiplication des circuits électroniques). Il s'agit donc d'un procédé avantageux, nettement différent de ceux qui font appel à la localisation statique de l'information.
