  • Publication number: 20180366359
    Abstract: A method and apparatus for de-chucking a workpiece is described that uses a swing voltage sequence. One example pertains to a method that includes applying a mechanical force from an electrostatic chuck against the back side of a workpiece that is electrostatically clamped to the chuck, applying a sequence of voltage pulses with a same polarity to the electrodes, each pulse of the sequence having a lower voltage than the preceding pulse, each pulse of the sequence having a lower voltage than the preceding pulse, and determining whether the workpiece is released from the chuck after the sequence of additional voltage pulses and if the workpiece is not released then repeating applying the sequence of voltage pulses.

  • Patent number: 10117949
    Abstract: A recombinant fusion protein comprising a human erythropoietin peptide portion linked to an immunoglobulin peptide portion is described. The fusion protein has a prolonged half-life in vivo in comparison to naturally occurring or recombinant native human erythropoietin. In one embodiment of the invention the protein has a half-life in vivo at least three fold higher than native human erythropoietin. The fusion protein also exhibits enhanced erythropoietic bioactivity in comparison to native human erythropoietin. In one embodiment, the fusion protein comprises the complete peptide sequence of a human erythropoietin (EPO) molecule and the peptide sequence of an Fc fragment of human immunoglobulin IgG1. The Fc fragment in the fusion protein includes the hinge region, CH2 and CH3 domains of human immunoglobulin IgG1. The EPO molecule may be linked directly to the Fc fragment to avoid extraneous peptide linkers and lessen the risk of an immunogenic response when administered in vivo.

  • Patent number: 10049277
    Abstract: A method and apparatus for tracking an object, and a method and apparatus for calculating object pose information are provided. The method of tracking the object obtains object feature point candidates by using a difference between pixel values of neighboring frames. A template matching process is performed in a predetermined region having the object feature point candidates as the center. Accordingly, it is possible to reduce a processing time needed for the template matching process. The method of tracking the object is robust in terms of sudden changes in lighting and partial occlusion. In addition, it is possible to track the object in real time. In addition, since the pose of the object, the pattern of the object, and the occlusion of the object are determined, detailed information on action patterns of the object can be obtained in real time.
