Patent CA-2150353-A1 (CA)
Title: Detection tag
Inventor: BATTERINK HENRI
IPC: G08B13/24
Filed: 1993-11-12
Abstract: Detection tag for a resonance de-tection system, comprising a support consisting of electrically insulating ma-terial and a resonant circuit supported thereby. The resonant circuit consists of an inductive element formed by a con-ductor track disposed on the support in a predefined pattern and of a capacitive element formed by at least two capacitor electrodes which are kept apart by the support and are constructed as electro-conductive electrodes regions. The ends of the track are connected to the one and to the other capacitor electrode, respec-tively. At least one electroconductive is-land region (6) is disposed on the support (1) so as to be adjacent to, and in the same plane as, one of the capacitor elec-trodes (7). The edges of the island re-gion (6) and the capacitor electrode (7), which face one another, are situated at such a distance from one another that a discharge gap is delimited therebetween.
Patent CA-2154978-A1 (CA)
Title: Data compression system
Inventor: CLARK ALAN DOUGLAS
IPC: G06F5/00
Filed: 1995-07-28
Abstract: A real-time method for improving data compression. The correlation between data characters being provided a modem (10) is determined. Two measures are used to determine the correlation between data characters: the shape of tree(s) (6) in encoding table (16) and the compression ratio (96). Once the correlation between data characters is determined using the two measures, the size of the encoding table (16) can be changed. If the data characters are not correlated, meaning the data is random or pseudo-random, the size of the encoding table is decreased. If the data characters are highly correlated, changing the size of the encoding table reduces time spent attempting to compress incompressible data and increases data compression for compressible data.

Abstract: Procédé d'accès radio utilisé pour faciliter la communication entre au moins une première station et une pluralité de deuxièmes stations. Tout d'abord, chaque signal destiné à être envoyé est tamponné au niveau d'une première station, puis les signaux sont divisés en segments de même longueur. Les segments de signaux destinés spécifiquement à une des deuxièmes stations prédéfinie sont envoyés à l'aide d'une tranche de temps correspondante (tranche 1) dans une trame multiplex temporelle se répétant de manière régulière. Les segments de signaux envoyés par la première station sont reçus au niveau d'au moins une des deuxièmes stations et les segments de signaux sont assemblés à partir des tranches de temps correspondantes successives (tranche 1) pour reconstruire ledit signal voulu. Une voie de fréquence d'émission (F1) spécifiquement associée à la tranche de temps de réception correspondante (tranche 1) est déterminée au niveau de la deuxième station. Pour terminer, un signal destiné à être envoyé à la première station est tamponné dans la deuxième station et comprimé pour être envoyé à l'aide de la voie de fréquence d'émission (F1) pendant presque toute la période pendant laquelle la deuxième station ne reçoit pas de signal.

IPC: G01P3/36
Filed: 1995-12-13
Abstract: An optical projection system is provided which may be used to build a compact, rugged, non-contact optical, length and/or speed measuring apparatus based on Laser Doppler Velocimetry (LDV). Such an apparatus may be used to measure the length and/or speed of continuously moving targets or industrial products produced continuously.

Title: Pilot control valve having means for recovering exhaust fluids
Inventor: ELLIOTT ANDREW C
IPC: F04B9/125
Filed: 1996-01-26
Abstract: A pilot control relay valve to change the directional flow of fluid to a piston (such as, for example, the piston of a chemical injection pump for injecting chemicals at a slow or rapid rate over a long period of time), but also allow the recovery of exhaust fluids under significant back pressure. The pilot control relay valve comprises an elongated valve member shiftable within a valve body between a first and second position. The first position allows communication of control fluid to a first pressure receiving surface while allowing exhausting of fluid from a third or opposing pressure receiving surface, thereby to initiate movement of the valve member against the back pressure of the exhaust fluid from its first position to a position equalizing the pressure acting on a second pressure receiving surface with the pressure of the control fluid, thereby causing the valve member to move to its second position. The valve member when it is in its second position allows communication with the third pressure receiving surface while allowing exhausting of fluid from the first pressure receiving surface for initially moving the valve member against the back pressure of the exhaust fluid from its second position while equalizing the pressure acting on the second pressure receiving surface to move the valve member to a position equalizing the pressure acting on the second pressure receiving surface with a pressure lower than the pressure of the control fluid for moving the valve member from its first position, whereby the operation is repeated ad infinitum.      Piping is connected to threaded exhaust ports in the valve body to communicate exhaust fluid to a reservoir where it is collected under pressure for further use.

Inventor: TONI DARRYL MARK
IPC: B29D24/00
Filed: 1994-08-29
Abstract: A composite sandwich structure which includes upper and lower skin structures (20, 22), first and second honeycomb core structures (24, 29), and an intermediate portion disposed between the first and second honeycomb core structures. The intermediate portion comprises a composite laminate (30), a barrier member (32) and a foaming adhesive layer (34) disposed between the composite laminate and the barrier member.  The foaming adhesive layer is of a type designed to expand when exposed to an elevated temperature.  The composite laminate and the barrier member operate to limit the expansion of the foaming adhesive layer into the open cells of the first and second honeycomb core structures.  The foaming adhesive layer, upon expansion,  applies pressure against the composite laminate. This pressure, acting concomitantly with the applied curing pressure and the elevated temperature, cures the laminate.  Furthermore, the expansion of the foaming adhesive urges the composite laminate and the barrier member apart so as to fill any core discrepancies, i.e., mistrimmed or damaged core, thay may exist in the honeycomb core structures.

IPC: G01B21/00
Filed: 1996-06-13
Abstract: An alignment and lighting system aligns and lights an optical fiber termination so that an inspection system can measure the eccentricity of an optical fiber core relative to the termination. The inspection system has an imaging system comprising a feature imager and one or more boundary segment imagers but preferably four in number, amachine vision system connected to the imaging system, and an alignment and lighting system for aligning the termination with the imaging system and lighting the termination without having to launch light therethrough. The feature imager is positioned to capture an image of the fiber core endface, and the one or more boundary segment imagers are positioned to capture an image of a corresponding boundary segment of the termination endface. The machine vision system determines the offset, or eccentricity, based upon the feature image and the one or more boundary segment images. The alignment and lighting system includes an alignment apparatus and a unique lighting scheme. The alignment apparatus has a plurality of alignment arms that are spaced apart via spacings to form a cross-shaped aperture that is engaged with the termination endface. Light is projected toward the exposed regions at a light projection angle that is outside the light acceptance angle associated with the fiber core. As a result, light is not generally received by the core, and light is scattered within and reflects out from the fiber cladding and the termination support material surrounding the cladding.
