| 20090245619 | IMAGE DENSITY-ADAPTED AUTOMATIC MODE SWITCHABLE PATTERN CORRECTION SCHEME FOR WORKPIECE INSPECTION - An image correction device for use in a pattern inspection apparatus is disclosed, which has automatic adaptability to variations in density of a pattern image of a workpiece being tested. The device is operable to identify a two-dimensional (2D) linear predictive model parameters from the pattern image of interest and determine the value of a total sum of these identified parameters. This value is then used to switch between a corrected pattern image due to the 2D linear prediction modeling and a corrected image that is interpolated by bicubic interpolation techniques. A pattern inspection method using the image correction technique is also disclosed. | 10-01-2009 |

| 20120022690 | ROBOT CONTROL APPARATUS - In an embodiment of the present invention, with the purpose of more accurately calculating a disturbance torque generated by an external force acting on a robot, friction parameters contained in algorithms, such as a friction coefficient and a dead-zone threshold value, are dynamically changed based on the mode of operation, the operation speed, and the like. In this manner, a drive torque is estimated with high accuracy. | 01-26-2012 |
