Patent number: 6526180Abstract: A pixel image enhancement system which operates on color or monochrome source images to produce output cells the same size as the source pixels but not spatially coincident or one-to-one correspondent with them. By operating upon a set of input pixels surrounding each output cell with a set of logic operations implementing unique Boolean equations, the system generates “case numbers” characterizing inferred-edge pieces within each output cell. A rendering subsystem, responsive to the case numbers and source-pixel colors, then produces signals for driving an output device (printer or display) to display the output cells, including the inferred-edge pieces, to the best of the output device's ability and at its resolution.Type: GrantFiled: June 3, 1999Date of Patent: February 25, 2003Assignee: Oak Technology, Inc.Inventor: Adam L.

Patent number: 6525164Abstract: Macrocyclic oligoesters and compositions comprising macrocyclic oligoesters are prepared from intermediate molecular weight polyesters. In one embodiment, a diol is contacted with a dicarboxylic acid or a dicarboxylate in the presence of a catalyst to produce a composition comprising a hydroxyalkyl-tenninated polyester oligomer. The hydroxyalkyl-terminated polyester oligomer is heated to produce a composition comprising an intermediate molecular weight polyester which preferably has a molecular weight between about 20,000 Daltons and about 70,000 Daltons. The intermediate molecular weight polyester is heated and a solvent is added prior to or during the heating process to produce a composition comprising a macrocyclic oligoester. An optional step is to separate the macrocyclic oligoester from the composition comprising the macrocyclic oligoester.Type: GrantFiled: August 31, 2001Date of Patent: February 25, 2003Assignee: Cyclics CorporationInventor: Gary R.

Patent number: 6521041Abstract: A SiGe monocrystalline etch-stop material system on a monocrystalline silicon substrate. The etch-stop material system can vary in exact composition, but is a doped or undoped Si1−xGex alloy with x generally between 0.2 and 0.5. Across its thickness, the etch-stop material itself is uniform in composition. The etch stop is used for micromachining by aqueous anisotropic etchants of silicon such as potassium hydroxide, sodium hydroxide, lithium hydroxide, ethylenediamine/pyrocatechol/pyrazine (EDP), TMAH, and hydrazine. For example, a cantilever can be made of this etch-stop material system, then released from its substrate and surrounding material, i.e., “micromachined”, by exposure to one of these etchants. These solutions generally etch any silicon containing less than 7×1019 cm−3 of boron or undoped Si1−xGex alloys with x less than approximately 18. Alloying silicon with moderate concentrations of germanium leads to excellent etch selectivities, i.e.Type: GrantFiled: April 9, 1999Date of Patent: February 18, 2003Assignee: Massachusetts Institute of TechnologyInventors: Kenneth C.

Patent number: 6522365Abstract: A method of recovering a pixel clock for generating a digital image from an analog video signal is presented. The on and off-transition times for the active video portion of a digital image and the image size defined in a video standard are used to generate a pixel clock. The analog video signal is digitized according to the pixel clock and the image size of the resulting digital image is compared with the image size defined in the video standard. The pixel clock frequency is adjusted in response to the image size comparison. The optimum phase of the pixel clock relative to the analog video signal is determined through a repetitive phase adjustment technique. A first image coordinate is determined for a pixel clock at one phase and a subsequent image coordinate is determined for a pixel clock after decrementing the phase of the pixel clock. The first image coordinate and the subsequent image are compared.Type: GrantFiled: January 27, 2000Date of Patent: February 18, 2003Assignee: Oak Technology, Inc.Inventors: Vladimir Levantovsky, Daniel J.

Patent number: 6517995Abstract: Elastomeric stamps facilitate direct patterning of electrical, biological, chemical, and mechanical materials. A thin film of material is deposited on a substrate. The deposited material, either originally present as a liquid or subsequently liquefied, is patterned by embossing at low pressure using an elastomeric stamp having a raised pattern. The patterned liquid is then cured to form a functional layer. The deposition, embossing, and curing steps may be repeated numerous times with the same or different liquids, and in two or three dimensions. The various deposited layers may, for example, have varying electrical characteristics, interacting so as to produce an integrated electronic component.Type: GrantFiled: March 14, 2000Date of Patent: February 11, 2003Assignee: Massachusetts Institute of TechnologyInventors: Joseph M.

Patent number: 6516540Abstract: The present invention discloses a ground-contacting system including 3D deformation elements having interiors filled with either a compressible fluid, such as a gas, or filled with other materials such as liquids, foams, viscous materials and/or viscoelastic materials. The 3D elements are designed to deform, distort,l or deflect in three mutually orthogonal directions simultaneously and are associated directly with the surfaces that routinely come in direct contact with a ground surface such as the underside of the sole and side portions of the shoe upper near the sole. The 3D elements are also designed to decrease the amount of force transferred to the wearers feet, legs, back, and joints due to their ability to distort three dimensionally and to dissipate the energy of foot fall into thermal energy.Type: GrantFiled: February 28, 2001Date of Patent: February 11, 2003Assignee: Adidas AGInventors: Roland Seydel, Simon Luthi, Richard Fumi, Kevin A.
