  • Patent number: 7606773
    Abstract: A genetic algorithms rostering system (20) with a workload and shift setting optimizer (22), a GA rostering engine (24) and a storage medium (26) is described. The GA rostering engine (24) dynamically shifts one or more shift lists of an initial shift list matrix based upon a shifting factor associated with each of the shift lists. Thereafter, the GA rostering engine (24) obtains an intermediate shift list matrix that is then fine-tuned by swapping individual shifts for each of the shift lists in the intermediate shift list matrix. A swapping factor for fine-tuning is associated with each of the shift lists and indicates a gene group with two or more genes. Each of the genes in the gene group is associated with an individual shift. Output of the rostering system (20) are rosters (28) represented in a matrix form.

  • Patent number: 7551762
    Abstract: The present invention provides a unique low cost vision inspection and classification system and methods for automatic inspection and classification of a microarray slide without manual intervention. The method first performs morphological dilation operation several times such that internal microarray spots are merged as a big connected component; then, the orientation of the merged spots, with respect to the X-axis and Y-axis is computed by computing the angle of the external boundaries of the connected component using Sobel XY operators for both edges and orientation determination, or using the moment-based algorithm for direct orientation determination; and the translational offset is determined by finding the X and Y centroids of the connected component. Moreover, the present invention provides threshold methods for classifying spots into normal spots, weak spots, missing spots, or overlapping spots.

  • Patent number: 7256598
    Abstract: A hybrid non-abrasive electrical test contact element of a test socket is taught. Unlike cantilever contact elements of the prior art, the contact element of the present invention is able to contact a lead of an integrated circuit device under test without abrading the plating on the lead. This is achieved by the contact element possessing multiple loops to allow the tip of the contact element to move not only downwards, but also sideways in a rocking and non-sliding motion. The tip of the contact is also shaped to contact the lead at only a radius corner of each lead so as not to affect the solderability of the lead. In addition, tests have shown that the contact element of the present invention has at least twice the working life span compared to another contact element of the prior art.
