Abstract: METHOD FOR USE OF MORPHOLOGICAL INFORMATION TO CROSS REFERENCE KEYWORDS USED FOR INFORMATION RETRIEVAL     Abstract A data processing method is disclosed for storing and retrieving text.  The storage part of the method includes the  steps  of  compiling  a  vocabulary  list  of  words occurring in the text and augmenting the vocabulary list with lemmas of the words in the text, as an augmented word list.   It then continues with the steps of compiling a cross reference table relating the lemmas of the words to locations of the words in the text and storing the text, the augmented word list and the cross reference table. The retrieval part of the method includes the steps of inputting a query word to access a portion of the stored text, searching the augmented vocabulary list using the query word as a search term,  and accessing the cross reference table with a lemma of the query word to locate the portion of the stored text.  The resulting invention enables a faster performance for "fuzzy" searches of text in documents, while enabling the cross reference lists used in the retrieval process, to be compactly stored.

The preferred method of closing the container comprises about any product contained therein between the open end of the container to substantially close the container.  The gathered portion is then twisted and open end of the container is folded about the gathered portion and secured to any site on the container by means of the adhesive strip. A pressure sensitive adhesive utilized in conjunction with the strip quick-tack and quick-peel characteristics and does not permanently adhere to itself.  The strip is usable over a broad range of temperatures and enables reclosing of a variety of containers both easily and effectively.
Patent CA-2008378-A1 (CA)
IPC: H05K13/08
Filed: 1990-01-23
Abstract: Abstract Inspection of a circuit board to detect missing and misaligned active and passive surface-mounted components and, respectively, is accomplished by first illuminating the board with top light to enhance the image of the passive components. The circuit board is then displaced, relative to a linescan camera trained on the board, so that the camera captures the image of successive strips of surface area running across the board perpendicular to its direction of movement. The images captured by the camera are stored and thereafter processed by an image-processing system to determine whether any passive component is missing or misaligned. The circuit board is then illuminated with side light to enhance the image of the active components. The circuit board is again displaced relative to the linescan camera so the camera captures the image of successive strips of surface area on the board. The captured images are stored and then processed by the image-processing system to detect whether any of the active surface-mounted components are missing or misaligned.

Title: A tachometer system for an internal combustion engine which senses an electromagnetic signal produced by a firing of the engine
Inventor: KRZYWICKI STANLEY J
IPC: G01P3/44
Filed: 1990-06-05
Abstract: A tachometer system for an internal combustion engine. The tachometer system uses one of two electromagnetic pulse sensing means to detect an electromagnetic signal produced by a firing of the engine.  The sensing device may be an antenna or an inductive pickup.  One of the signals is chosen and processed.  A parameter indicative of pulse timing in the output signal is determined.  This parameter is most advantageously a time between different ones of the output signals.  The parameter is then converted into a value indicative of revolutions per unit time of the engine. The converting structure is advantageously formed by a personal computer.

Abstract: A clamping assembly for releasably holding a tool holder having a shank includes a tool support member having a bore extending along a longitudinal axis. A locking mechanism is disposed in the axial bore for securing the tool holder to the support member. The locking mechanism includes a lock rod having first and second contact surfaces mounted in the support member. The lock rod moves along the longitudinal axis between a locked position and a release position. A wedge rod is mounted in the support member for reciprocal movement along an axis angularly disposed with respect to the longitudinal axis. The wedge rod has first and second wedge surfaces which incline in parallel fashion from opposite edges of the wedge rod. First and second force transmitting elements are interposed between the wedge surfaces of the wedge body and the contact surfaces of the lock rod. When the lock rod is moved in first direction, the first force transmitting element is moved outward with respect to the transverse axis into contact with the first support surface and pushes the lock rod towards a locked position. When the wedge rod is moved in a second direction, the second force transmitting element is moved outward with respect to the transverse axis into engagement with the second contact surface of the lock rod and moves the lock rod towards a release position.

Filed: 1991-04-26
Abstract: ABSTRACT OF THE DISCLOSURE          A control system for guiding a free-steered vehicle such as a dump truck used in a mining environment along a path.  In one preferred embodiment there is a scanning laser directed upwardly to scan a coded reference of retroreflective material mounted above the vehicle on a mine roof.  There is a sensor to detect laser signals retroreflected from the reference, the sensor and laser forming a laser unit.  The vehicle is center-articulated and there is a laser unit on each of the bogeys.  The rear bogey has a dump box and the rear unit is retractably mounted on the underside of the dump box.  The units are connected to a microprocessor to which are relayed signals from the laser sensor and which directs vehicle operations in response thereto.  The coded reference has a central longitudinal guidance strip and on each side there is a set of bar code markers and speed markers.  When travelling in one direction along the path the guidance strip and one of the sets of bar code markers and speed markers provide instructions for guidance of the vehicle and to direct other operations such as dumping.  When travelling in the other direction along the path the guidance strip and the other set of markers provide instructions for the microprocessor.  In another preferred embodiment the path is endless and only one guidance strip and set of markers is required.  Further optional aspects of the system include a microwave based collision avoidance system, and an infrared signal-based remote control system.
