Patent number: 6293026Abstract: A method of measuring the height of a foot arch precisely and easily using two essential heights of the foot arch is disclosed. In the method, a foot cast is primarily cast by pouring plaster into a foot mold. Thereafter, a first intersecting point and a second intersecting point are determined. The first intersecting point is determined by making a first line and a third line intersect. The second intersecting point is determined by making a second line and the third line intersect. The first line is a straight line extending from the center of the second toe to the center of the heel end. The second line is a straight line extending from the center of the big toe to a point spaced apart inwardly from the center of the heel end by ⅛ of the total distance of the heel end. The third line is a center line of the transverse arch of the foot. Finally, a first height and a second height are measured while the foot pattern is set in an upright position.Type: GrantFiled: December 8, 1999Date of Patent: September 25, 2001Assignee: Osan CollegeInventors: Eun K.

Patent number: 5635991Abstract: A color signal processing system for a color television receiver which can improve the transition characteristic of a color difference signal, using the transition region of a luminance signal. The system includes a differentiator for differentiating the transition region of an input luminance signal, and a color difference signal processor for processing an input color difference signal by controlling the transition region of the color difference signal in accordance with the differentiated luminance signal. Thus, the transition characteristic of the color difference signal is compensated for in proportion to the transition characteristic of a luminance signal.Type: GrantFiled: March 3, 1995Date of Patent: June 3, 1997Assignee: Goldstar Co., Ltd.Inventor: Dong H.
