| 20100290696 | METHOD OF MEASURING MEASUREMENT TARGET - In order to measure a measurement target on a PCB, height information of the PCB is acquired by using a first image photographed by illuminating a grating pattern light onto the PCB. Then, a first area protruding on the PCB by greater than a reference height is determined as the measurement target by using the height information. Thereafter, color information of the PCB is acquired by using a second image photographed by illuminating light onto the PCB. Then, the first color information of the first area determined as the measurement target out of the color information of the PCB is set as reference color information. Thereafter, the reference color information is compared with color information of an area except for the first area to judge whether the measurement target is formed in the area except for the first area. Thus, the measurement target may be accurately measured. | 11-18-2010 |
| 20100295941 | SHAPE MEASUREMENT APPARATUS AND METHOD - A shape measurement apparatus includes a work stage supporting a target substrate, a pattern-projecting section including a light source, a grating part partially transmitting and blocking light generated by the light source to generate a grating image and a projecting lens part making the grating image on a measurement target of the target substrate, an image-capturing section capturing the grating image reflected by the measurement target of the target substrate, and a control section controlling the work stage, the pattern-projecting section and the image-capturing section, calculating a reliability index of the grating image and phases of the grating image, which is corresponding to the measurement target, and inspecting the measurement target by using the reliability index and the phases. Thus, the accuracy of measurement may be enhanced. | 11-25-2010 |
| 20110002527 | BOARD INSPECTION APPARATUS AND METHOD - An inspection method includes photographing a measurement target to acquire image data for each pixel of the measurement target, acquiring height data for each pixel of the measurement target, acquiring visibility data for each pixel of the measurement target, multiplying the acquired image data by at least one of the height data and the visibility data for each pixel to produce a result value, and setting a terminal area by using the produced result value. Thus, the terminal area may be accurately determined. | 01-06-2011 |
| 20110002529 | METHOD FOR INSPECTING MEASUREMENT OBJECT - An inspection method for inspecting a device mounted on a substrate, includes generating a shape template of the device, acquiring height information of each pixel by projecting grating pattern light onto the substrate through a projecting section, generating a contrast map corresponding to the height information of each pixel, and comparing the contrast map with the shape template. Thus, a measurement object may be exactly extracted. | 01-06-2011 |
| 20110191050 | METHOD OF INSPECTING A THREE DIMENSIONAL SHAPE - In order to inspect a three dimensional shape, a predetermined inspection target component formed on a board is selected as the measurement target, a shape of the inspection target component is acquired, a reference point of the inspection target component is detected, relative location information of a polarity mark formed on the inspection target component with respect to the reference point is acquired, and it is judged whether the inspection target component is good or bad by checking whether the polarity mark exists or not by using the relative location information with respect to the reference point. Thus, the location of the polarity mark may be accurately known, and polarity inspection may be more easily and accurately performed. | 08-04-2011 |

| 20090157223 | ROBOT CHATTING SYSTEM AND METHOD - A robot chatting system includes an interface for generating a chatting text including robot motion having a text part and a motion part; a robot chatting server for providing a robot chatting service between chatting persons, using the chatting text including robot motion; a first unit for generating motion control data corresponding to the motion part of the chatting text including robot motion; a second unit for converting the text part of the chatting text including robot motion into speech data; and a robot for outputting the speech data through a speaker and simultaneously motioning based on the motion control data. Therefore, when the user inputs text and its corresponding motions and sends the input text, the other user's robot reads the text and performs the relevant motions, thereby providing the robot chatting service of good quality. | 06-18-2009 |
| 20100316039 | APPARATUS AND METHOD FOR GENERATING RANGING CODE - An apparatus for generating a ranging code extracts a ranging code in each ranging mode, using a ranging code table storing one period data in bytes of the PN code according to a reference UL PermBase number, and an offset table that stores byte offsets for the start positions of the PN codes of the reference UL PermBase number and the other plurality of UL PermBase numbers and bit offsets in the byte including the start positions, on the basis of the PN code according to the reference UL PermBase number. | 12-16-2010 |
| 20110054684 | METHOD AND SYSTEM FOR TRANSFERRING/ACQUIRING OPERATION RIGHT OF MOVING ROBOT IN MULTI-OPERATOR MULTI-ROBOT ENVIRONMENT - In an operating system having a first controller configured to manage one or more robots included in a first region, and a second controller configured to manage one or more robots included in a second region adjacent to the first region, a method for enabling the second controller to acquire an operation right of N robots (where N is a natural number equal to or greater than 1) operated by the first controller, the method includes: transmitting a control mapping status (CMS) containing an operation right change message to the first controller, upon reception of an operation right request signal from a user of the N robots; and checking a connection status of the N robots, upon reception of the CMS containing the operation right change message from the first controller, and acquiring an operation right by providing CMS acquisition information and control mapping information to the robots included in the second region. | 03-03-2011 |
| 20110153073 | FAULT TOLERANCE METHOD AND APPARATUS FOR ROBOT SOFTWARE COMPONENT - An apparatus for performing fault tolerance against a failure occurring during driving robot software components includes: a component executor for executing the robot software components, which are assigned with one thread from an operating system and have a same priority and cycle, by using the assigned thread; and an executor monitor for periodically monitoring the operation of the component executor and determining whether or not there is a failure in the robot software components executed by the component executor. The apparatus further includes: an executor manager for generating the component executor which is assigned with the robot software components having the same priority and cycle and, when the executor monitor determines that there is a failure in the execution of the robot software components, generating a new component executor. | 06-23-2011 |
