Title: Method of and apparatus for inspecting end of object for defect
Inventor: MINATO NOBUHIRO
IPC: G06T1/00
Filed: 1992-01-13
Granted: 2001-07-31
Abstract: A method of and an apparatus for inspecting an end of an object for a defect by which not only a defect caused by deformation of an end of an object in a horizontal direction but also another defect caused by deformation in a vertical direction can be detected with a high degree of accuracy. Light from an end portion of an object is received by a pair of one- or two-dimensional image sensors and disposed at a predetermined angle relative to each other, and brightness outputs of individual picture elements of the image sensors are stored into memories. From the stored signals, a bright line produced by light from an edge of the object end portion is detected for each image sensor, and a position of the bright line is calculated as a digital amount from a number of picture elements for each image sensor. Then, the digital amounts are added and subtracted between the image sensors. A defect is judged from results of the addition and subtraction.

Patent CA-2064859-C (CA)
Inventor: BARAN JOZEF B
IPC: H05K1/14
Filed: 1990-08-22
Granted: 2000-01-11
Abstract: A multi-layer printed circuit board is constructed to suppress radio frequency interference (RFI) generated by high frequency clock and data signals therein. Suppression is achieved by positioning clock lines (254) carrying the clock signal on a first voltage reference layer (152) proximate to a second voltage reference layer (154). The two layers shield the clock signal from the signal lines on other layers. Noise may be further reduced by forming bridges (270) in the second voltage reference layer (154) proximate to the clock lines so that the bridges (270) span the width of the clock line. Capacitors are also preferably utilized to further suppress radiated noise. The capacitors provide AC coupling between the first and second voltage reference layers (152, 154) so that a low impedance path is provided for high frequency noise generated by the clock signal. The second voltage reference layer (154) thus operates as an effectively continuous shield between the bridges (270).

Title: Methods and apparatus for selecting semantically significant images in a document image without decoding image content
Inventor: WITHGOTT M MARGARET
IPC: G06V30/40
Filed: 1992-09-01
Granted: 1999-02-23
Abstract: A method and apparatus for processing a document image,  using  a  programmed  general  or  special  purpose computer, includes forming the image into image units, and at least one image unit classifier of at least one of the image units is determined, without decoding the content of the at least one of the image units.   The classifier of the at least one of the image units is then compared with a classifier of another image unit.  The classifier may be image unit length, width, location in the document, font, typeface,  cross-section,  the  number  of  ascenders,  the number  of  descenders,  the  average  pixel  density,  the length of the top line contour,  the length of the base contour,  the  location of  image  units  with respect  to neighboring  image  units,  vertical  position,  horizontal inter-image unit spacing, and so forth.   The classifier comparison can be a comparison with classifiers of image units of words in a reference table, or with classifiers of other image units in the document.  Equivalent classes of image units can be generated, from which word frequency and significance can be determined. The image units can be determined by creating bounding boxes about identifiable segments  or  extractable  units  of  the  image,  and  can contain a word, a phrase, a letter, a number, a character, a glyph or the like.

IPC: B29C45/17
Filed: 1993-07-27
Granted: 1997-01-28
Abstract: A process for injection molding of thermoplastic materials which includes a nozzle body having a bore to provide a flow path for molten thermoplastic.  One end of the nozzle body is adapted for connection with a sprue of an associated mold body, and the other is adapted for connection with an end of an associated injection molding machine.  The nozzle body has a shut-off valve fluid pin housing adapted for reciprocating movement in the nozzle bore to control the flow of plastic through the nozzle body.  The shut-off valve fluid pin housing also includes a body having an adjustable fluid pin with a tip portion and a fluid passage formed in the body and open at the tip portion and the other end of the fluid passage communicating with a source of two pressurized fluids, one in vapour and liquid phase and another in gas.  The shut-off valve is actuated to allow thermoplastic material to flow and subsequently a first pressurized fluid vapour is allowed to flow to form a hollow cavity in the thermoplastic material and then terminated and a second fluid which is a gas is allowed to flow into the cavity followed by the liquid of the first fluid.  The fluid flow is controlled by the fluid pin shape and stroke adjustments.  After the thermoplastic material has set, the pressurized fluid is vented through the fluid pin housing passage into a fluid condenser for recovery of the vapour and liquid and then into atmosphere.

Title: Device and process for measuring solid concentrations in liquids
Inventor: KANNGIESSER HARTMUT
IPC: G01N21/51
Filed: 1993-06-01
Granted: 1998-12-15
Abstract: In a method for measuring solid concentrations in liquids, the light from two differently modulated sources (Q1, Q2) directed on the liquid is measured at the same time and processed in a combined multi-beam measuring process consisting of a 90.degree. light scatter (Q1, P, D4; Q2, P, D3) and back-scatter process (Q1 P1, D1; Q2, P3, D2) and the solid concentration is found therefrom. The process is suitable for the simultaneous measurement of both extremely low and extremely high solid concentrations by using a 90.degree. light scatter process for low concentrations and a back scatter process for high concentrations. The multi-beam process which is based on two measurements through exactly the same window areas makes it possible effectively to compensate for undesired soiling of the window areas. Mechanical devices for cleaning the window areas and to eliminate interfering light scatter are proposed.
