  • Patent number: 6947176
    Abstract: A method is provided for correcting lightness of an image using a multiscale retinex. Lightness of a subject pixel of an original image is corrected using a convolution operation of a surround function and surround pixels with respect to the subject pixel of the original image, and the convolution operation is performed over a plurality of scales. The surround function has a simplified model such that a value of the surround function is changed in a stepwise way along two axes orthogonal to each other.

  • Patent number: 6937347
    Abstract: A lateral-shear interferometer utilizes two relatively thick glass plates bonded together in a single block with a tilted air gap between opposing inner surfaces. The thickness of the glass plates is selected to be sufficiently large to separate the output beams from the light reflected from the top and bottom surfaces of the block, thereby eliminating the need for antireflection coatings. The shear interferometer is combined with an external mirror mounted on a tilt stage actuated by a computer-controlled tilt actuator to perform phase-shifting interferometric analysis in conventional manner.

  • Patent number: 6799120
    Abstract: The present invention includes methods for generating combinatorial libraries on solid phase supports in which increased productivity is achieved by pooling all common steps in synthesis without using a tracking or coding system to record the synthetic history of each compound. Methods for generating combinatorial libraries in which containers with random mixtures of solid phase particles are divided and combined together in non-random ways without the exchange of particles between containers are also provided. Various products are optionally produced in multi-stage syntheses according to the invention, such as oligomers and synthetic non-repetitive organic molecules. The methods additionally relate to the identification of each library component without adding extra synthetic, physical, optical, or electronic encoding steps during library synthesis. Combinatorial synthetic systems are also provided.

  • Patent number: 6674312
    Abstract: A differential signal reception device and method for supporting variable threshold levels. The device flexibly makes an input to the decision circuit appear to an outside driving circuit as if the decision circuit were a purpose-built input network supporting a fixed impedance input into either a floating or fixed DC termination voltage. The device further allows the internal decision process to support a variable threshold level when deciding logical 1/0 values and to attenuate the users input signal range for the purpose of making sure the range of the user's signals do not exceed the operating range of readily available decision circuit (limiting amplifier) integrated circuits.

  • Patent number: 6625546
    Abstract: Methods of identifying predicted or actual structures of members of a chemical or physical library are provided. The methods provide for the direct identification of compound structure following combinatorial synthesis using molecular mass measurements of individual compounds, thereby eliminating the necessity of encoding synthetic steps. The analysis of mass spectrometric data for sets of related compounds reveals compounds that are missing in a group of related compounds and identifies compounds that do not belong to a group of related compounds due to unexpected chemical, physical, or biological transformations. The methods may be applied to any group of compounds originating from chemical reactions where one reactant is common to the synthetic transformation. One particular application of these methods is in the analysis of the products of combinatorial synthesis. Systems, computer programs products, and kits are additionally provided.

  • Patent number: 6006022
    Abstract: A cross-linked development and deployment system that links system design, simulation, real-time emulation, integration, and in-system verification to system implementation in the field, creating final products that are field programmable systems on printed circuit boards or field programmable systems on silicon. In a preferred embodiment, hardware and software models are created and verified in an integrated co-development environment. These models can be synchronized with each other and can also be used for in-circuit emulation and in-system verification of the system under development. Once the system has gone through verification and completed system integration, the system design database that has been generated from that testing is used to program either a field programmable printed circuit board or a field programmable system on silicon.
