Title: Height adjustment mechanism for a chair backrest
Inventor: SZMADZINSKI JOHN A
IPC: B60N2/02
Filed: 1996-08-05
Abstract: A mechanism is provided for adjusting the height of the backrest (10) relative to a chair seat. The adjustment mechanism for releasably retaining the backrest (10) in a plurality of selected positions relative to a seat permits the chair to be shipped in a "knocked down" condition and easily assembled by the consumer. The adjustment mechanism includes a channel member (30) that is secured to the backrest, and a support member (40) carried by the chair that is slidably received in the channel member (30) and rigidly locked in selected positions. The support member (40) has vertically aligned rack teeth (72, 74) and the backrest has a movable catch (48) having pawls (52, 54) that are adapted to engage the rack teeth (72, 74). Movement of the catch (48) places the pawls (52, 54) into engagement with the rack teeth (72, 74) to prevent the downward movement of the backrest (10) from a selected vertical position.

Title: Data compression for animated three dimensional objects
Inventor: CHEN HOMER H
IPC: G06T13/00
Filed: 1998-02-11
Abstract: Data which represents an animation sequence of a three dimensional object at a series of discrete time frames is compressed by identifying characteristic features of the object; generating a quadrangular mesh representation of the object, whereby the object is mathematically defined by dividing it into one or more regions and hierarchically representing each region by a mesh, each mesh including three coordinate matrices which define the positions of nodes within the mesh; selecting from the mesh representation of the features a set of animation parameters which are capable of specifying changes in the mesh corresponding to the animation of the object; compressing each region mesh by applying pyramid progressive coding to the coordinate matrices for the mesh; storing the initial values for the animation parameters at the beginning of the animation sequence; and, at each time frame after the beginning of the animation sequence, estimating the current values of the parameters and compressing each parameter by estimating the change in the value of the parameter by subtracting its stored value for the previous time frame from its current value, quantizing the estimated difference, applying entropy coding to the quantized difference and updating the stored value with the decoded value.

Title: Mono-allelic mutation analysis for identifying germline mutations
Inventor: PADADOPOULOS NICKOLAS
IPC: C12Q1/68
Filed: 1996-08-23
Abstract: A diagnostic strategy for detection of inherited diseases caused by germline mutations is based on somatic cell hybridization. Each allele of a human gene involved in the inherited disease is isolated in a somatic cell hybrid. The products of the isolated human allele are then observed in the absence of the other allele of the human.

Patent CA-2241161-A1 (CA)
Inventor: JAKAB GYULA
IPC: H03H7/00
Filed: 1998-06-19
Abstract: The present invention relates to a method and apparatus for controlling the analog voltage level, and thereby the analog power level, of analog signals propagating on a data transmission medium. The apparatus comprises a voltage divider including two branches, one of the branches being provided with a bipolar transistor acting as a switch. When the transistor is in a closed condition it conducts and the voltage divider attenuates the input signal. When the bipolar transistor is in the opened condition it does not conduct and the input signal is not attenuated. To prevent the input signal from acquiring a negative polarity (that should be avoided since the bipolar transistor conducts in a single direction), the input signal is combined with a DC component of a magnitude sufficient to avoid any polarity changes. A digital control signal input at the base terminal of the transistor determines its state of conduction and thus controls the level of attenuation manifested by the apparatus.

Title: Method and system for providing password protection
Inventor: JREIJ ELIE A
IPC: H04M1/247
Filed: 1997-02-28
Abstract: Access is granted to a portion of a computing system, such as to a configuration menu of a telephone system. In order to grant access, a password is received from a user. A variable password is also calculated. The variable password varies with time. For example, the variable password varies with a current date and with a time of day stored by the computing system. The password received from the user is compared with the calculated variable password. When the password received from the user is equal to the calculated variable password, access is granted.

Title: R-stat
Inventor: GOSSELIN PIERRE
IPC: B64B1/02
Filed: 1998-10-20
Abstract: Le R-Stat est un dirigeable à air chaud de deuxième génération. Il a la particularité de produire sa chaleur en vase clos, laquelle chaleur sert à la fois à rendre l'appareil plus léger que l'air et à le propulser, surtout à le propulser dans la direction voulue. Sa façon d'être propulsé et sa forme en disque en font un aéronef excessivement facile à manoeuvrer. Cette même forme et son format plus réduit lui permettent aussi d'atteindre des vitesses plus élevées que les dirigeables actuellement disponibles sur le marché. Contrairement à ces derniers, le RStat est beaucoup moins dépendant des caprices de la température et ne nécessite aucune équipe au sol pour décoller, voler et atterrir. Finalement, il devrait pouvoir être produit au quart du prix des dirigeables actuels.

Patent CA-2256193-A1 (CA)
Title: Clamp de surete
Inventor: RENE YVES
IPC: F16L3/13
Filed: 1998-11-25
Abstract: Dans les systèmes de tubulure d'érablière, l'étanchéité des raccords adapteurstubulures, est un facteur primordial dans le bon fonctionnement du système de tubulure en général. L'étanchéité dépend de l'étreinte de la tubulure sur l'adapteur, généralement créée par les barbelures ( barb ) qui se situent sur l'extrémité de l'adapteur (ex : chalumeau, té bouchon ou régulier, union, autre) à être insérée à l'intérieur de la tubulure. Grâce à l'invention du présent clamp de sûreté, la réparation des raccords non ou peu étanche est de beaucoup plus simple et moins risquée. L'étreinte de la tubulure aux adapteurs se trouve accentuée compte tenu de la pression supplémentaire exercée par le clamp de sûreté à l'extérieur de la tubulure contre l'adapteur et ses barbelures.

Abstract: A connecting device for connecting segments of concrete or similar settable material, the device including a plastics connector part (1) of dumb-bell-like form and two housing parts (4) for receiving respective opposite portions (2) of the connector part. Each housing part has an internal tapered form so that, when the housing parts are set in opposed concrete segments to be connected and the connector part is inserted in the housing parts, the taper of each housing part causes the connector part to stretch thereby providing a tensile load between the opposite portions (2) of the connector part. Preferably, the taper has two angles of slope, the leading section causing the connector part to stretch and the hind section of taper causing the connector part to be trapped therein by relieving a measure of the stretch.

Title: Speech recognition manager
Inventor: CATALLO LEO R
IPC: G10L15/22
Filed: 1997-07-24
Abstract: A speech recognition manager receives representations of one or more words from a speech decoding system (106) and interprets the received words based upon the current context state so as to provide extremely accurate, flexible, extendable and scalable speech recognition and interpretation. The speech recognition manager limits the number of words that the speech decoding system (106) can recognize in a given context state in order to increase the speed and accuracy of the speech recognition process. Whenever the context state changes, the manager loads a new list of words that can be recognized for the new context state into the speech decoding system (106) so that while the speed and accuracy of the speech recognition process is increased, the total grammatical structure recognized can be easily increased as well.
