Abstract: A method for testing insulation resistance of a stator and performing post-processing includes preparing a sample by an operator, testing insulation resistance by measuring whether a resistance value is equal to or greater than a predetermined value by applying a predetermined test voltage after settling the sample in purified water and maintaining the sample under a predetermined pressure; removing moisture at a predetermined rotation speed for a predetermined period of time by putting the tested sample in a device providing rotational force, removing moisture from the sample by applying compressed air for a predetermined period of time; removing moisture by applying heat for a predetermined period of time, drying and removing moisture by applying hot air to the sample for a predetermined period of time; stabilizing the sample, and removing the sample that has completed all of the steps and putting the sample into a manufacturing line by the operator.

Abstract: A notching apparatus for a secondary battery includes a lower body configured to support an electrode plate which includes a first area coated with an active material and a second area not coated with the active material, the electrode plate to be transferred in a first direction, an upper body configured to vertically move above the lower body, a die on the lower body and arranged to face the second area, a punch hole passing through the die and including a first punch hole, a second punch hole, and a third punch hole sequentially arranged in the first direction, and a punch on the upper body, insertable into the punch hole as the upper body moves downward, and configured to cut the second area.

Abstract: Provided are a stepped battery and a method and device for manufacturing the stepped battery, and more particularly, a stepped battery and a method and device for manufacturing the stepped battery, which processes a tent part of a separation film formed on a stepped part of the stepped battery, to prevent a defect from occurring during a subsequent process. A stepped battery manufacturing method includes preparing a stepped battery (10) having a tent portion of a separation film (16) formed on at least one stepped surface (18), and pressing the tent portion by using a press tool (30) having a shape corresponding to the stepped surface (18) of the stepped battery (10).

Abstract: Techniques, apparatus and systems are described for selecting the recommended image among sequentially captured images. In aspect, a method of selecting the recommended image includes measuring a brightness value and a sharpness value for each of sequentially captured images. The measured brightness and sharpness values are combined for each image to obtain a combined value for each image. The recommended image is selected from among the sequentially captured images based on the obtained combined values.

Abstract: A method of correcting image distortion and an apparatus for processing an image using the method are provided, where the method can overcome the disadvantages of the conventional methods of correcting lens distortion and can minimize image quality degradation at outer portions,. The method includes: receiving an image from a wide-angle lens; extracting a distortion coefficient of the distortion in the image caused by the wide-angle lens; correcting the distortion of the image by using the extracted distortion coefficient; and displaying a corrected image. The apparatus includes: a wide-angle lens for receiving an image; an image processing unit comprising a distortion coefficient extracting unit for extracting a distortion coefficient of distortion in the image caused by the wide-angle lens and a distortion correcting unit for correcting the distortion of the image using the extracted distortion coefficient; and a display unit for displaying a corrected image.
