Patent CA-2141011-A1 (CA)
Title: Stylus-Based Keyboard Key Arrangement
Inventor: HANSON KARRIE J
IPC: G06F3/0488
Filed: 1995-01-24
Abstract: A small, stylus-based keyboard in which the arrangement of the keys is a function of predetermined estimated probabilities of the occurrence of variouspossible sequences of keystrokes. Sequences of keystrokes which are estimated tohave a high likelihood of occurrence result in the associated keys being placed adjacent to one another. In this manner, the ease, speed and accuracy of use of small, stylus-based keyboards may be improved. Multiple keys representing the same character may be provided to increase the likelihood that keys included in high probability sequences will be adjacent. The probability estimates may be determined based on a statistical analysis of a preselected sample of text. In addition, keys may be color-coded for ease of identification and grooves may be cut into the housing between adjacent keys for ease of stylus operation. Lights (e.g., light-emitting-diodes) may also be inserted between adjacent keys or beneath the keys for purposes of word identification or next letter prediction.

Title: Audio visual dubbing system and method
Inventor: CHEN HOMER H
IPC: H04N5/93
Filed: 1995-03-16
Abstract: A system and method for replacing the original sound track of a video or film sequence depicting a dubbee with an audio signal indicative of substituted utterances by a dubber associates frames of a stored or transmitted sequence with facial feature information associated with utterances in a language spoken by the dubber. The frames of thesequence are modified by conforming mouth formations of the dubbee in accordancewith the facial feature information using a look up table relating detected dubber utterances to a set of speaker independent mouth formations or actual mouth formations of the dubber. In accordance with the present invention, a viewer of a currentlytransmitted or previously stored program may manually select between viewing theoriginal broadcast or program or viewing a dubbed version in which a second audio track indicative of utterances in a language different than that of the dubbee is reproduced. Once such a selection is made, the second audio track is utilized toconform the mouth movements of the dubbee to those of someone making the dubber's utterance.

Title: Reagent for immunoagglutination and immunoanalytical method
Inventor: UENO TAKAHISA
IPC: G01N33/544
Filed: 1994-02-01
Abstract: An immunoagglutination reagent comprising the carrier liposomes covalently immobilizing an antigen or an antibody to assay an antibody or an antigen on the basis of the agglutination level is provided, which is characterized in that assaying can be done at a high sensitivity in a region of short wave length where the change in turbidity caused by the agglutination can be measured in an enhanced fashion. Liposomes are used as the carrier of the reagent for immunoagglutination.  An antibody or an antigen is immobilized onto the surface of the liposome, and a water-soluble compound or a gelled compound is entrapped in the liposomes.  The substance entrapped in the immunoagglutination reagent enhances the change in turbidity via the agglutination caused by the antigen-antibody reaction.

Patent CA-2154367-A1 (CA)
Title: Process for pretreatment of non-isotropic cylindrical products
Inventor: LEACH DAVID COLIN
IPC: B29C43/32
Filed: 1994-02-04
Abstract: Many thermoplastic polymers suffer from time dependent deformation when used at elevated temperature. The present invention relates to a method of preconditioning a non-isotropic composite cylindrical member (11). The method involves fitting the cylindrical member (11) onto a mandrel having an outside diameter greater than the inside diameter (I.D.) of the cylindrical member (11) and heating the mandrel and cylindrical member (11) to a temperature sufficient to cause thermal deformation of the mandrel and substantially irreversible thermal deformation of the cylindrical member (11). This allows thermoplastic polymers to be used more extensively, for example, as a replacement for more conventional metals.

Title: Carburation device in particular for internal combustion engines
Inventor: PICCININI GIUSEPPE RAOUL
IPC: F02M9/10
Filed: 1995-10-24
Abstract: In order to obviate the drawbacks of fluid-dynamic character which affect the traditional carburettors equipped with control valves of throttle or of guillotine type, the carburation device (1, 1A, 1B, 1C) provides for the feed duct (6, 6A-6C) to be a tubular portion made of an elastic material constrained at its ends and that at least one pair of relatively movable blades (10) act on said elastic feed duct (6, 6A-6C) on its outer surface, squeezing it in a perpendicular direction relatively to its axis (8). The surface area of the cross-section of the inner bore of said duct (6, 6A-6C) varies taking (relatively to the fuel stream flowing through it) a gradually convergent-divergent shape, i.e., without sharp changes in said inner bore cross-section surface area, and the fuel stream has hence a fluid-dynamically optimal motion independently from the actual revolution speed of the engine.

Inventor: QI HUA
IPC: G06F19/00
Filed: 1996-03-22
Abstract: An apparatus for simulating an ocular optical system simulates a retinal image produced by a human eye through an optical lens. Optical system data are produced from an optical system including a cornea, a pupil, an intraocular lens, a retina, etc. Based on the optical system data, point spread functions each indicative of a distribution on an image plane of light emitted from a certain point are calculated by PSF (Point Spread Function) calculating means. Image data are subjected to convolutional integration with the point spread functions, determining retinal image data. The retinal image data are converted into display data, which are supplied to a display unit to display a retinal image thereon. The retinal image displayed on the display unit is an image that would be actually formed on the retina of the human eye, and provides an accurate objective indication of how the image is seen by the patient.

Title: Method for Applying Zipper to Film at Tube on a Form-Fill-and-Seal Machine
Inventor: VAN ERDEN DONALD
IPC: B65B9/20
Filed: 1996-03-26
Abstract: A method for manufacturing reclosable packages on a form, fill and seal machine includes the step of providing a continuous sheet of thermoplastic material with  a  Z-fold extending longitudinally therealong before the sheet is wrapped around a filling tube for forming and filling the packages.   The Z-fold is maintained on the tube of thermoplastic material thus-formed until it reaches a loop opener on the outside surface  of  the  filling  tube.    The  loop opener transforms  the  Z-fold  into  a  loop  extending longitudinally along and outwardly from the filling tube and  from the tube of thermoplastic material wrapped therearound.   Simultaneously,  a continuous plastic zipper having a pair of mutually interlocking profiles is directed into the tube of thermoplastic material along a channel on the outside surface of the filling tube.   The zipper is ultimately guided out from the channel, through the loop opener and into the loop, and is sealed thereto to form the reclosable openings for the plastic packages being manufactured.
