Title: Line draw method.
Inventor: MARTIN KEVIN BAYARD
IPC: G06T11/20
Filed: 1992-01-27
Abstract: Disclosed is a line-draw method and apparatus that draws lines at fast speeds. Lines are drawn a pixel at a time and a number of algorithms are employed to determine the pixels to be drawn. The line-draw method determined is a function of line length, typical length categories are short (49), medium (199), and long (248). For short lines (49), a table look-up method is employed (111). For longer length lines (199, 248), a multi-pixel segment (burst method) is employed (247 603). Burst methods are line-draw methods which draw lines using a plurality of multi-pixel segments to draw the lines where each segment is characterized as having a number (U) of unconditional pixels which are always drawn and an actual number (A) of conditional pixels which are drawn. The actual number (A) is any number up to a maximum number (C) of conditional pixels which can be drawn.

Patent EP-0602119-A4 (EP)
Title: Photo-acoustic leak detection and method.
Inventor: MCRAE THOMAS G
IPC: G01M3/20
Filed: 1992-08-20
Abstract: An apparatus and method for the rapid detection and location of a gas leak. A collimated beam of light is scanned across the component under test which has been pressurized with a tracer gas that strongly absorbs the light. When the light passes through the gas emerging from the source of the leak, the light energy absorbed by the gas produces an acoustic emission which is detected by a microphone. The resulting signal may be processed either as an alarm to notify the operator that a leak is present, or, it may be processed in coordination with the beam scanning mechanism to indicate exactly where the leak is located on the component.

Title: Compressible ply for printing blankets.
Inventor: CASTELLI FRANCESCO
IPC: B29C35/02
Filed: 1993-03-24
Abstract: A laminated printing blanket having compressible and resilient properties and a method for its production are provided. The compressible characteristics are provided by disposing an intermediate layer having substantially uniformly distributed voids of substantially uniform size between the base ply and the working surface of the printing blanket. The voids of the compressible intermediate layer are formed by introducing high melting point microspheres formed from thermoplastic resins into an elastomeric matrix, coating said microsphere containing elastomeric matrix upon an upper surface of the base ply and then vulcanizing the coated base ply at a temperature of between about 80-150° C. for between about one and six hours to form the compressible layer having substantially uniform compression characteristics. Once all of the layers of the blanket are stacked, a final vulcanization treatment at between about 132-160° C. for between about 30 minutes to sixteen hours at a pressure between about atmospheric and 6 kg/cm2 in a known manner completes the curing of all the layers to produce a laminated printing blanket.

Title: Membrane dielectric isolation ic fabrication.
Inventor: LEEDY GLEN J
IPC: G11C29/00
Filed: 1993-04-02
Abstract: General purpose methods for the fabrication of integrated circuits (24, 26, 28,... 30) from flexible membranes (20, 36) formed of very thin low stress dielectric materials, such as silicon dioxide or silicon nitride, and semiconductor layers. Semiconductor devices (24, 26, 38,... 30) are formed in a semiconductor layer of the membrane (36). The semiconductor membrane layer (36) is initially formed from a substrate (18) of standard thickness, and all but a thin surface layer of the substrate is then etched or polished away. In another version, the flexible membrane is used as support and electrical interconnect for conventional integrated circuit die bonded thereto, with the interconnect formed in multiple layers in the membrane. Multiple die can be connected to one such membrane, which is then packaged as a multichip module. Other applications are based on (circuit) membrane processing for bipolar and MOSFET transistor fabrication, low impedance conductor interconnecting fabrication, flat panel displays, maskless (direct write) lithography, and 3D IC fabrication.

Title: Pit detector and method.
Inventor: ROGERS JOHN E
IPC: G01N33/02
Filed: 1993-09-10
Abstract: A method and apparatus for detecting the presence of an impurity within a substantially spherical object, such as a pit within a piece of stone fruit as it passes through an inspection zone. An infrared point source light emitting diode positioned on one side of the inspection zone transmits a single light beam across the inspection zone. A linear CCD array for generating a signal that is proportional to the intensity of the light transmitted through the fruit as the fruit passes through the inspection zone is provided and an optical slit for collimating the light beam on the CCD array are provided. An infrared filter is positioned between the lens and the CCD array. Thus, as the fruit passes through the inspection zone and is illuminated by the infrared light source and the intensity of the light transmitted through the fruit is received by the CCD array, a two-dimensional analyzable bit map representative of the cross-section of the object's density is produced.

Dans un autre mode de réalisation, les emplacements présélectionnés sur la plaque de fond (97) sont des puits à rebords (98) remplis de facteurs chimiotactiques (105-1) et de témoins (105-2). Le revêtement hydrophobe (109) est utilisé pour limiter le mouvement du fluide sur la membrane du filtre (101) ainsi que sur la plaque de fond (97). Dans des modes préférés de réalisation, des matériaux d'occlusion ou des monocouches de cellules sont utilisés pour limiter encore la circulation du fluide par gravité.
