Abstract: A method of forming circuit lines on a substrate by applying a roughened conductive metal layer using a copper foil carrier. The copper foil is etched away, leaving the roughened conductive metal embedded in the surface of the substrate. The conductive metal may be treated to remove an oxide layer. A photoresist may also be applied over the treated conductive metal layer to define a fine line circuit pattern. The photoresist defining the fine line circuit pattern is then removed to expose trenches in accordance with the desired circuit pattern. Copper is applied into the trenches over the exposed conductive metal, and the remaining photoresist, and conductive metal underlying the remaining photoresist, is removed to finish the fine line circuit pattern.

Title: Small catalyst particle addition to slurry reactor
Inventor: HOWSMON GREGG JOHNSTON
IPC: C07C29/156
Filed: 1999-10-29
Granted: 2010-01-26
Abstract: Small particle size catalysts having an average particle size of less than 20 or 10 microns, which agglomerate when contacted with a hydrocarbon liquid, are easily dispersed in the hydrocarbon liquid by first forming a mixture comprising the catalyst particles and one or more non-acidic, liquid polar oxygenates, such as an alcohol, ketone, ester, ether or mixture thereof. The mixture is contacted with the hydrocarbon liquid in which the particles then readily disperse. This process is useful for adding fresh or regenerated small particle size catalyst to catalytic hydroprocessing process slurries, including a reactive Fischer-Tropsch hydrocarbon synthesis slurry. One to four carbon atom alcohols are preferred oxygenates for use with a Fischer-Tropsch slurry.

Abstract: A camera-based touch system includes at least one pair of cameras having overlapping fields of view and a touch surface encompassed within the overlapping fields of view across which a pointer is moved. The cameras of the at least one pair acquire images at intervals asynchronously. In order to estimate the position of the pointer relative to the touch surface from image data acquired by the at least one pair of cameras, the images are synthetically synchronized. During this process, for each camera in the pair, each acquired image is processed to determine the position of the pointer therein and the position of the pointer is recorded together with a timestamp representing the time elapsed between a reference point common to the cameras and the time the image was acquired. Successive pairs of recorded positions are interpolated to generate interpolated positions and the interpolated positions are recorded together with synchronization times representing times the images would have been acquired had the cameras been synchronized. Interpolated positions generated by the cameras having equivalent associated synchronization times are determined and these interpolated positions are triangulated to estimate the position of the pointer relative to the touch surface.
