Patent CA-2190164-A1 (CA)
Title: A real time handwriting recognition system
Inventor: JOURJINE ALEXANDER
IPC: G06K9/22
Filed: 1996-03-27
Abstract: A handwritten character recognizer having an input cluster buffer and a point buffer with dynamic and static stroke feature extraction and segment analysis byconical boundaries for identification of stroke segments (dynamic stroke featureextractor, static stroke feature extractor).  A stroke recognizer compares single copies of idealized stroke representations with hierarchically approximated multiple scaled topological representations of a current stroke, followed by stroke proportion discrimination comparing a selected topological representation of the current stroke with boundaries defined by linear combinations of features of direct and reversed ideal stroke prototypes to provide a stroke identification.  A cluster recognizer maintains a time ordered current stroke buffer and previous stroke buffer and constructs a per stroke area of influence list.  The time ordered buffers are scanned to generate a spatially ordered window buffer.  A position discriminator assigns character meanings to clusters of strokes in the window buffer.  The buffer scanner is responsive to a current stroke having spatial coordinates located between previous strokes for reordering the stroke buffers and determining a new cluster meanings.  An editor is responsive to an editing gesture or combination of two strokes for directing the stroke buffer controller to modify the strokes in the stroke buffer accordingly.

Title: Lifeline-fire safety training unit
Inventor: SHAW OWEN COVERLY
IPC: G09B19/00
Filed: 1996-12-04
Abstract: Every year fires occur in occupied residences and institutions - hospitals, long term care centres, chronic care facilities, apartment buildings and hotels. Employees in most of these facilities are required to initiate an alarm or take other steps to save lives and property. This requires familiarity with the fire alarm system. However, many employees simply panic during an emergency because they are not sufficiently practiced in the use of the fire alarm system. This fire alarm training unit called LIFE LINE was designed to provide efficient mass training of employees and residents in the identification and use of the fire protection devices.
Patent CA-2192588-A1 (CA)
Inventor: BLAKELY JOHN H
IPC: G01R19/02
Filed: 1996-12-10
Abstract: The dynamic range of a current transformer (CT) is increased without reducing the scaling of measurements at the low end of the dynamic range by designing the core of the CT to saturate only after about 90 electrical degrees of the maximum current to be measured. The measurements taken during this first 90 electrical degrees before the core saturates are doubled to in effect add measurements representing the mirror image of the first 90 electrical degrees. Timing of the digitized samples taken during the first 90 electrical degrees is adjusted to account for core reset energy errors, by determining the rate of change of current just after a zero crossing and selecting an empirically determined value of current for timing the start of the measurement samples.

Patent CA-2206166-A1 (CA)
Title: Sub-pixel dataform reader
Inventor: WANG YNJIUN
IPC: G06K9/50
Filed: 1996-10-10
Abstract: Sub-pixel processing of image data representing a dataform, such as a 2D bar code, enables reading of dataforms including more data/smaller elements, without costly increases in sensor and memory capacity. Whole pixel processing is employed for pixel-per-element resolutions of two or better. Sub-pixel cell edge transition location in image data is enhanced by use of a dynamically implemented noise margin applied with bands of gray scale values (150, 152) designated within the enveloppe of applicable gray scale maximum (119) and minimum (120) values. Sub-pixel cell edge transition location employs selection of transition segments (121-124), subject to the noise margin, and determination of a dynamic threshold (158) for each relevant transition segment (122). The intersection of the threshold (158) and the transition segment ( 122) is then indicative of the location of the cell edge transition along a sampling line crossing the dataform. The process is repeated for successive cell edges along image data sampling lines crossing successive rows of dataform elements. Run length data representing cell edge transition locations is constructed and usable for dataform decoding.
Patent CA-2207231-A1 (CA)
Title: Programmable membrane switch input/output system
Inventor: STRUTHERS RICHARD JOHN
IPC: H01H13/70
Filed: 1997-06-06
Abstract: A programmable membrane switch input/output system is disclosed.  The system comprises a membrane switch having a matrix layout embedded in a plastic film with a plurality of switches located at specific locations on the film. Output lines from the matrix layout are electrically connectable to a conversion unit which converts the output signals from a first code dependent on the matrix layout and the position of the switches to a second code which is independent of the position of the switches and the matrix layout.  The conversion unit can convert the output signals into a serial code which can be transmitted serially from the conversion unit to a processing device located remotely from the membrane switch. By transferring the output signal serially from the conversion unit to the processing device, the cable can have fewer lines and less space is taken on the processing device for the connection. The conversion unit comprises a microprocessor and a memory unit which stores a conversion table to convert the output signals from the first code to the second code.  The memory means is re-programmable so that the conversion unit can be re-programmed to convert output signals from the first code into a third code, different from the first code and the second code.  The conversion unit can also filter the signal and end key rollover by transmitting only one output signal to the processing  device  in  a  predetermined  time  period.    The conversion unit drives LEDs and seven segment displays on the membrane switch in response to signals received from the processing device to output information.   By locating the conversion means proximate the matrix layout the noise caused by the resistance of the cable is decreased, thereby improving the signal and the reliability of the system.   A method of inputting information from a membrane switch to a processing device by utilizing the conversion unit is also disclosed.

Title: Apparatus and method for preventing ink resoftening on a printed web
Inventor: HANSEN DANIEL J
IPC: B41F23/04
Filed: 1996-03-20
Abstract: An offset printing apparatus (10) has a fluid-cooled nip roll (52) which, in use, is specially designed to press a hot, rapidly moving, endless printed and dried web into intimate contact with the first downstream chill roll (20) while avoiding damage to the web (14), nip roll (52), or chill roll (20), and while avoiding ink picking by the web surface contacted by the nip roll.  Employing the nip roll in the system also permits the use of a substantially shorter dryer and fewer chill rolls as compared to a conventional system operating at the same web speed. A coolant circuit (300) for the nip roll (52) preferably includes a warmup loop (331) which temporarily circulates warm fluid through the nip roll (52) when the system is first taken off-line, thereby preventing condensate formation or frost formation on the nip roll (52).

Title: Vessel with a disconnectable riser supporting buoy
Inventor: ISNARD JEAN-LOUP
IPC: B63B22/02
Filed: 1997-09-19
Abstract: The invention relates to a vessel which is attached to the sea floor by at least one anchor line.  A riser support buoy (9) is releasably connected to the vessel.  The anchor line or anchor lines are attached to the vessel outside the area of the riser support buoy (9) such that the buoy can be detached from the vessel independently from the attachment of the anchor lines.  By releasing the riser support buoy while maintaining the anchor lines in place, the buoy can be released for maintenance purposes, inspection of the buoy body or the riser without the vessel going adrift.  Also are the forces between the vessel and the buoy reduced as the anchor lines are not attached to the riser supporting buoy.  The riser supporting buoy may be provided with stabilisation lines (45, 45') which on one end comprise a ballast weight (46, 46').
