  • Patent number: 8481887
    Abstract: A method for laser machining through micro-holes having desired geometric cross-section requirements in a thin, substantially homogenous material.
    Type: Grant
    Filed: April 29, 2008
    Date of Patent: July 9, 2013
    Assignee: Electro Scientific Industries, Inc.

  • Patent number: 8173931
    Abstract: To better address these problems, one or more characteristics are measured from a work piece (28). The measurement information is used to select a preferred predetermined laser processing recipe from a lookup table. The laser processing recipe is then used to process the work piece (28). The lookup table of laser processing recipes can be established from theoretical calculations, from trial an error by an operator, from an automated systematic recipe variation process with post process testing, or from some combination of these or other methods. An automated process can also reduce operator errors and may store measurement values for convenient tracking of work piece characteristics.

  • Patent number: 7437207
    Abstract: An apparatus and method performing a sequence of processing steps on a load supported by a processing plate. The load can include a single sheet on which a plurality of applications are performed or can include a plurality of panels on which respective applications are performed. For each application, at least one coarse target and at least one panel target are used to adjust the programmed coordinates for that application. After the first application of the load is processed using the coarse and panel targets, coarse and panel targets are located for the second application. Using the alignment provided by these targets, the second application is processed. Each subsequent application is similarly aligned and processed.

  • Patent number: 6224926
    Abstract: The present invention, provides natural-source compositions having consistent, effective antibrowning and antioxidant characteristics. Additionally, the present invention provides methods for making the antibrowning/antioxidant compositions of the present invention. More specifically, the present invention provides natural-source, browning and oxidizing inhibitor compositions comprising S-sinapyl-L-cysteine, N-L-&ggr;-glutamyl-S-sinapyl-L-cysteine, S-sinapyl glutathione, or various mixtures thereof. Methods for making such natural, antibrowning/antioxidant compositions from pineapple juice and/or from pineapple processing plant waste streams include efficient and effective separation of the present invention compositions from unwanted sugars, acids, phenolic compounds, and other undesirable compounds present in pineapple juice and/or pineapple processing plant waste streams.
