Abstract: In a roller gap measurement system and a roller gap measurement method using the roller gap measurement system, the roller gap measurement system includes a light source, a refractive part, a sensor part and an image processing part. The light source is configured to provide an incident light toward the gap between first and second rollers. The refractive part is configured to receive a complex light passing through the gap between the first and second rollers, and configured to refract the complex light. The sensor part is configured to receive the refracted light and configured to image a complex pattern. The image processing part is configured to obtain a gap information between the first and second rollers, based on the imaged complex pattern.

Abstract: A connector assembly having a moving plate to protect terminals and maintain alignment within a first connector is provided. The connector assembly includes a first connector having a coupling space formed therein and having a plurality of first terminals disposed in the coupling space, a moving plate movably installed in the coupling space and having a terminal hole through which the first terminal passes, and a second connector coupled to one side of the first connector and having a holder moving the moving plate in the coupling space. A cam groove is formed in an external surface of the moving plate. A moving pin, insertable and movable in the cam groove, is formed on the holder, and when the moving plate and the holder are coupled, the moving plate moves in a direction, perpendicular to a coupling direction.

Abstract: A connector assembly has a movable plate for protecting terminals and maintaining alignment in a first connector. The connector assembly includes a first connector having a coupling space formed therein and having a plurality of first terminals disposed in the coupling space, a moving plate movably installed in the coupling space and having a terminal hole through which the first terminal passes, and a second connector coupled to one side of the first connector and moving the moving plate in the coupling space. A step portion is formed on the inner surface of the first connector. A hinge portion is formed on a side surface of the moving plate to rotate at a predetermined angle, and an end of the hinge portion can be locked or released from the step portion.

Abstract: A method for providing a video signal, and a descramble card and a video apparatus using the same are disclosed. The video apparatus includes a first interface which receives a scrambled video signal, and outputs the scrambled video signal, a second interface which transmits the scrambled video signal to a storage medium connected with the video apparatus, and a controller which controls the first interface to transmit the scrambled video signal to the second interface. Accordingly, a personal video recorder (PVR) function is provided to a premium broadcast content.

Abstract: A display apparatus includes: a display unit; a receiving unit which receives a broadcasting signal including a program having a viewer rating and extracts the viewer rating from the program; an image processor which performs image processing on the received program; and a controller which compares a user-specific viewable rating with the extracted viewer rating, and controls the image processor to display a predetermined image when the extracted viewer rating is not included in the viewable rating.

Abstract: A display apparatus and method is provided having a display part for receiving an image signal from the outside and displaying an image, comprising a user window generator for generating a history window comprising at least one display parameter for determining a display state of the image displayed in the display part, and at least one history of prechanged values corresponding to the display parameters, and a controller for controlling the user window generator so that the history window is displayed in the display part by receiving a control signal for changing the display parameter. Thus, the display apparatus and control method can be used for facilely adjusting a plurality of display parameters using changed and prechanged values discernable from a history window and which determine a display state of a displayed image.
