Patent CA-2109073-A1 (CA)
Inventor: BALFANZ ECKHARD
IPC: G01N33/00
Filed: 1993-02-25
Abstract: The invention concerns a process and a device for taking samples in particular from waste gases containing substances of moderate and low volatility in a gas or aerosol phase. To this end, partial current is diverted and conducted into a separation area, where the substances to be tested from the partial current, either in dust-bonding form or in the condensate, undergo a separation process and are fixed. When applied to a specific sample for the analysis of organic substances of medium to low volatility, in particular polychlorinated dibenzo(p)dioxins (PCDD) and polychlorinated dibenzofurans (PCDF), the separation process can be restricted according to the invention in such a way that the partial current, together with the gaseous and liquid water portion contained in it, undergoes a two-stage separation process, where it is drawn through an inert dust-filter region, and drawn through a region filled with an adsorber such as a synthetic adsorbent resin with a multi-reticular structure. The gaseous water contained in the waste gas is not removed before being drawn into the adsorber region, nor is the dew point lowered by dilution.

Inventor: DRAKE DONALD J
IPC: B41J2/135
Filed: 1994-06-07
Abstract: An improved thermal ink jet printhead is formed by the alignment and bonding of an anisotropically etched silicon wafer channel plate, containing a plurality of channel grooves, to a silicon wafer heater plate, containing a plurality of heating and addressing elements which are covered by a patterned thick film layer. The printhead enables better bonding of the two plates by compensating for raised lips or edges formed on the outside edge of opposing last pits in an array of pits located in the thick film layer that are created while photofabricating the pits in the insulating layer. The fabrication sequence compensates for the raised edges by including a non-functional straddling channel that nullifies the standoff created by the raised edge and a corresponding additional non-functional pit that positions the raised edge away from the functional channels and nozzles.

Title: System and method for processing test measurements collected from an internal combustion engine for diagnostic purposes
Inventor: MARKO KENNETH A
IPC: G01M15/05
Filed: 1994-07-15
Abstract: Abstract A system and method for processing test measurements collected from an internal combustion engine that is cold-tested for diagnostic purposes. Test measurements are collected from an engine. The test measurements are "pre-processed" by filtering and subsampling techniques so that Principal Component Analysis can be applied to condense the quantity of test measurements while still retaining a statistically accurate indication of a majority of the original measurements. The pre-processed test measurements are then passed through one or more classifiers including: a Neural Network classifier, a Fuzzy Logic classifier, a cluster-based classifier (or "Spherical"classifier) and a Genetic Program classifier. Results from these classifiers canbe used to obtain a verdict about an engine (i.e., whether the engine is "normal" or "faulty").

Patent CA-2137491-A1 (CA)
Title: Automated benchmarking with self customization
Inventor: WACLAWSKY JOHN G
IPC: H04L12/26
Filed: 1994-12-07
Abstract: The method enables realtime establishment and maintenance of a standard of operation for a data communications network.  The process begins by monitoring the network over some period of time to build benchmark data sets.  The benchmark data sets contain a standard of operation for the network, which is historicallycategorized by either traffic type or activity.  This standard of operation is accumulated by the intelligent monitoring facilities.   After a period of accumulation, the benchmark is used to determine whether data taken from currentmonitoring activity indicates normal network behavior.   Network monitoring information is analyzed using criteria in modules that have an interface to an expert system.  The criteria modules evaluate the current monitored data againstthe prior benchmark collected data.   The criteria module determines if the current network operating characteristics are outside the bounds of normal behavior.  If they are, then alerts and logs of information can be sent to the expert system.  The expert system can perform network control routing changes, or close down applications, or allocate additional bandwidth as required.  In addition, the expert system can modify the characterization of the currently monitored data for historical purposes by supplying information to the benchmarkmanager regarding traffic types, activity, heuristic accuracy and changes between current and past behavior.  In this manner, auto benchmarking can be accomplished with self customization, in an improved manner.
