Patent CA-2228746-A1 (CA)
Inventor: CYPHELLY IVAN
IPC: F17C13/04
Filed: 1996-08-06
Abstract: An injection circuit with an injection pump (7), an injection duct (6) and a double connecting line to the high-pressure bottle (11) to be filled allows the high-pressure bottle to be filled from an intermediate reservoir (1) or directly from the compressor (2) with no significant heating. The injection circuit dissipates the generated heat either by means of heat exchangers (15) or by mixing in the intermediate reservoir (1). The process is automated by means of a differential pressure switch (9) associated to a temperature sensor on the injection duct (6).

Title: Method of enhancing the signal-to-noise within the pixel image of a hand entered symbol
Inventor: MELEN ROGER D
IPC: G06V10/10
Filed: 1998-03-04
Abstract: An input carrier sheet 12C for document distribution system 10 carries input symbols hand entered by the user into pre-existing constraint grids 12. The constraint grids may be printed in continuous tone or halftone. The print only partially covers the underlying carrier, permitting the exposed carrier to reflect light. The grids have sufficient pigment to be visible to the user, but insufficient pigment to form foreground pixels along with the hand-entered stroke when detected during the scanning. The signal (symbol)-to-noise (carrier) ratio is enhanced by  reducing the pigment content of the constraint grids which increases the reflectivity of the grids. The S/N may be further enhanced by placing the strokes of the hand-entered symbols on top of the grid which occults some of the grid pigment. The S/N is further enhanced by highly reflective brightening agents in the grid print, and by aperture effect during scanning.
Patent CA-2232164-A1 (CA)
Inventor: RAZ RYAN S
IPC: G06T7/00
Filed: 1996-09-18
Abstract: A neural network assisted multi-spectral segmentation method and system.  According to the invention, three images having different optical bands are acquired for the same micrographic scene of a biological sample. The images are processed and a cellular material map is generated identifying cellular material. The cellular material map is then applied to a neural network. The neural network classifies the cellular material map into nuclear objects and cytoplasmic objects by determining a threshold surface in the 3-dimensional space separating the cytoplasmic and nuclear regions. In another aspect, the neural network comprises a hardware-encoded algorithm in the form of a look-up table.

Title: Method of identifying recurring code constructs
Inventor: UMANETZ AUTUMN
IPC: G06F9/44
Filed: 1998-11-19
Abstract: A method of identifying recurring or common logical code elements within the source code of a computer application. Parsing of the source code of a set of files within the application produces a syntax tree which is then traversed to identify blocks of code. A fingerprint is created for each block of code, each fingerprint containing a characteristic for each type of statement located within the block. The characteristic consisting of a vector containing: the statement type, the number of occurrences of the statement, the number of bytes of data input to the statement and the number of bytes of data output from the statement.      The user may select that only certain types of statements are to be considered in creating a fingerprint. The user may also chose to aggregate types of statements into a single characteristic when creating the fingerprint. The fingerprints for each block of code are then submitted to a Bayesian classification engine which places the blocks of code into common groups based upon their fingerprints and displays them to the user. The user may then browse the selected groups to determine if there exist modules within the application that may be reused, redeployed or re-engineered.

Abstract: A method and a positioning door jig for selecting a suitable coating door jig is disclosed. A coating door jig is temporarily connected between a door opening at a side of a vehicle body to be coated and a slide door so as to enable forward and rearward movement of the slide door. The coating door jig forms a constrained linkage for guiding the slide door along a predetermined locus. The coating door jig is selected depending on a kind of automobile to be coated by the use of a positioning door jig. The positioning door jig forms a non-constrained linkage comprising mechanismic elements same as those of the constrained linkage and another additional mechanismic element. After temporarily connecting the positioning door jig between the slide door and the door opening, the kinematic pair position connecting the additional mechanismic element and one of the said mechanismic elements is adjusted so as to specify relative positions of the respective mechanismic elements. The suitable coating door jig is selected based on the specified relative positions of the mechanismic elements.

Filed: 1999-04-29
Abstract: A system and method provide a generalized reminder system in an interactive broadcast environment, that enables a viewer to quickly establish reminders for both broadcast events and non-broadcast events, and have such reminders displayed at an appropriate future time. The system includes a broadcast that broadcasts programs, such as television programs and commercial advertisements, and interactive applications associated with various such programs. The interactive applications include reminder interactive applications which have reminder data which describe a future time for displaying a reminder and a description of the event for which the reminder is desired. The broadcast programs and reminder interactive applications are received in broadcast receiver which displays the programs. A viewer viewing a program signals the broadcast receiver to establish a reminder for an event related to the program. The broadcast receiver stores the reminder data from the reminder interactive application, and initiates a timer that expires at the desired future time. When the timer expires, the broadcast receiver displays the event description for the reminder. Reminders may be established and displayed for both broadcast events and non-broadcasts events, as the description of the event is contained in the reminder data.

Title: Actuator assembly with calibration means and electrical power switch apparatus incorporating the actuator assembly with calibration means
Inventor: ULERICH PHILLIP L
IPC: H01H73/36
Filed: 1999-05-07
Abstract: An actuator assembly for an electrical power switch apparatus, the actuator assembly having a housing and a plunger positioned within the housing where the plunger is movable between a set position and an actuated position. The plunger includes a compression spring to provide a pre-load thereto that biases the plunger away from the set position and toward the actuated position. A magnet contained in the housing and positioned proximate to the plunger establishes a magnetic force which overcomes the pre-load of the compression spring and maintains the plunger in a set position. A coil assembly, that when energized, produces an electromagnetic force which bucks the magnetic force established by the magnet allowing the plunger to be propelled by the compression spring to the actuated position. A screw extends through an opening in the plunger for engagement with the compression spring so that rotation of the screw results in the adjustment or calibration of the pre-load of the compression spring.
