Abstract: Disclosed is a weld portion inspection method using thermal image sensing, wherein the method includes heating the weld portion using Joule heat; and determining whether the weld portion is defective based on a temperature increase pattern of the weld portion by the heating.

Abstract: Provided are a virtual optical input device and a method of controlling the same. In the method, a portion of an input means such as a finger, and a portion of a shadow of the input means generated by a light source are detected through image processing. Physical variations formed between them are used to detect the touch contact of the input means, calculate the position of the input means, and input the corresponding command. Accordingly, it is possible to provide various input patterns.

Abstract: A system for programming an interactive learning device, such as electronic toy, using a web server includes a first processing unit having a web server for providing a control module used for remote processing, a second processing unit linked to the first processor through the communication medium to exchange data with the first processor, an interactive device, such as a robot toy pet, having at least a processor and a memory and adapted to communicate with the first processing unit. The interactive device includes a sensor for collecting data and formulating a learned module. The interactive device receives the control module from the first processing unit and sends the learned module. The control module is updated with more advanced function to be performed by the interactive toy in response to the content of the learned module.

Abstract: An apparatus and a method for discriminating between analog and digital video signals in a high definition VCR are disclosed.

Abstract: An improved tape tension control apparatus for a VCR capable of preventing tape from getting out of a tension post due to the rapid movement of a tension arm by providing a tension arm movement delay member at the time of loading/unloading the tape, which includes a tension arm movement delay member disposed at a predetermined portion of the tension arm for preventing a rapid movement of the tension arm at the time of loading/unloading the tape.
