  • Self-healing coatings using microcapsules
    Publication number: 20060042504
    Abstract: Self-healing coatings incorporate microcapsules of about 60-150 microns diameter that contain film formers and dust suppression compounds suitable for controlling spalling of lead dust, for example. In one embodiment, a primer paint is mixed with these microcapsules and applied by brushing or rolling. After the coating has cured, any physical compromise of the coating results in microcapsules bursting to release liquid that fills and seals the compromised volume. The microcapsule contents protect the underlying substrate from damage and repair some of the outer coating. In one application, embodiments of these self-healing coatings seal existing lead-based paint for suppression of lead dust. In another embodiment, microcapsules are provided separately to enhance commercially available products.

  • Methods and apparatus for real-time business visibility using persistent schema-less data storage
    Publication number: 20050228805
    Abstract: The invention provides methods for enterprise business visibility that transform any of marketing, e-commerce and transactional from a plurality of legacy and other databases into resource description framework (RDF) syntax. This information can be time-stamped (e.g., with expiration dates) and stored in a central data store. Answers to queries are discerned by applying genetic algorithm-based search techniques to the holographic store, with the confidence levels of those answers is based in part, for example, on the time-stamps of the triples.

  • System and Method for the Identification of Chemical Mechanical Planarization Defects
    Publication number: 20050223805
    Abstract: The present invention presents a novel application of a wavelet-based multiscale method in a nanomachining process chemical mechanical planarization (CMP) of wafer fabrication. The invention involves identification of delamination defects of low-k dielectric layers by analyzing the nonstationary acoustic emission (AE) signal collected during copper damascene (Cu-low k) CMP processes. An offline strategy and a moving window-based strategy for online implementation of the wavelet monitoring approach are developed.

  • Methods and apparatus for querying a relational data store using schema-less queries
    Publication number: 20050187926
    Abstract: The invention provides, in one aspect, a method of searching an RDF triples data store of the type in which the triples are maintained in accord with a first storage schema. The method includes inputting a first query specifying RDF triples that are to be identified in the data store. That first query assumes either (i) that the triples are stored in a schema-less manner (i.e., with no storage schema) or (ii) that the triples are maintained in accord with a second storage schema that differs from the first. The method further includes generating, from the first query, a second query that specifies those same RDF triples, yet, that reflects the first storage schema. That second query can be applied to the RDF triples data store in order to identify and/or retrieve the desired data.

  • Rapid coating process and its application to lead-acid batteries
    Patent number: 6889410
    Abstract: A precursor chemical compound is applied to a surface sought to be coated, and subjected to a rapid thermally activated chemical reaction process (RTACRP) in which the temperature is quickly raised and lowered. The desired coating is formed from the precursor chemical compound by a chemical reaction at the elevated temperature. The structural/chemical integrity of the surface is preserved due to the use of RTACRP. The approach may be used to manufacture a high-energy density lead-acid battery.
