Patent CA-2192023-A1 (CA)
Inventor: JAMALI HAMADI
IPC: G06V30/10
Filed: 1996-12-04
Abstract: Method and apparatus for separating touching characters within an optical character recognition (OCR) computer (1). An input document (20) is scanned by scanner (2), forming a set of scan lines (3). A segmentation process (4) is performed on the scan lines (3) to create a set of segmented image boxes (5).      Candidate characters within the image boxes (5) are classified by a classification module (6), based upon a library of stored models (7). When the candidate characters have high degree of confidence, they are classified and coded into a binary form (8), such as ASCII. Those candidate characters that are not classified are processed by a touching character decision module (9) to determine whether a series of separation modules (10-14) is to be invoked. The execution of modules (10-13), followed by the reexecution of modules (4) and (6), may or may not cause all of the touching characters to be separated. Any touching characters that remain are subjected to one or more reprocessing cycles. The reprocessing can entail examination (14) of adjacent scan lines (3), shifting of separation threshold T by separation threshold determination module (10), or re-execution of deconvolution step (12) with changed parameters or structure.

Inventor: GIESSUEBEL KATHLEEN A
IPC: H04Q3/00
Filed: 1995-11-20
Abstract: A platform for connecting to a CCS7 network for supporting concurrently running CCS related applications. Copies of the SUs flowing through the network are sent to the platform where the FISUs, LSSUs and MSUs are filtered to provide the desired SU type for each of the applications. The MSUs are filtered by MSU category and MSU type within category into groups of MSUs of particular interest to the applications, respectively. Linked lists of filter elements associated with the respective linksets of the CCS7 network perform the filtering by comparing category and type fields to the MSU categories and types to form the groups. Filter change data received at a user interface is utilized to modify the filters.

Title: Sporting field illuminating lighting fixtures having improved light distribution
Inventor: LEADFORD KEVIN F
IPC: F21S8/00
Filed: 1997-07-31
Abstract: Luminaires intended to deliver maximal light flux to a playing field with improved uniformity, the invention provides primary reflector structures having shaped facets, the several reflectors being capable of maximizing lumen delivery onto the playing field when considered relative to economy of manufacture.  In certain embodiments of the invention, a shielding device or flux manager is employed for producing target extinctions by management of flux to precisely pass flux nearby original arc and through a second bounce off the reflector structure to direct that flux back into the beam.  A virtual arc is thus produced in proximity to the original arc with the virtual arc acting as a second source.          The flux manager acts to reduce glare and "spill" light. Performance optimization is further provided in embodiments using the flux manager through additional use of a multi-faceted reflector insert which re-aims light which would have been incident on portions of the reflector structure and which light is blocked by the flux manager.  The improved light distribution provided by the luminaires of the invention allow use of fewer luminaires for a given playing field lighting performance.

Title: Efficient utilization of chlorine and/or moisture-containing fuels and wastes
Inventor: MURRAY ROBERT G
IPC: F01K3/18
Filed: 1996-06-05
Abstract: A process for enhancing the fuel form, raising the energy content, and lowering the level of impurities of low rank coals and/or carbonaceous wastes, like Municipal Solid Waste (MSW), Refuse Derived Fuel (RDF), and sewage sludge, by providing the low rank fuel, carbonaceous waste, or mixtures thereof ans a slurry in water of processable viscosity. This feed slurry is heated under pressure (118), usually in the presence of an alkali (109), to a temperature at which a significant physical and molecular rearrangement occurs, characterized by the splitting off of a substantial proportion of the oxygen bound in the low rank coal or carbonaceous waste as carbon dioxide (147). At these conditions, solid particles in the feed slurry (103) lose much of their fibrous and hydrophilic character, and are broken up into smaller particles of char, resulting in a slurry of dramatically improved rheology, i.e., capable of a much higher solids concentration (or energy density) at processable viscosity.
