Patent number: 9546926Abstract: A method for inspecting a light source module for defects includes preparing a board on which a light emitting device and a lens covering the light emitting device are installed. A current is applied to the light emitting device to turn on the light emitting device. The lens is imaged with the light emitting device turned on. A central symmetry denoting a symmetry of light emission distribution from the center of the lens is calculated based on the obtained image, and the calculated central symmetry is compared with a reference value to determine whether unsymmetrical light emission distribution has occurred. Various other methods and apparatuses for inspecting light source modules are additionally provided.Type: GrantFiled: December 23, 2014Date of Patent: January 17, 2017Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Won Soo Ji, Oh Seok Kwon, Dae Seo Park, Ka Ram Lee

Publication number: 20040198524Abstract: In a golf simulation system, a setting plate for locating a golf ball is provided in a striking zone, and a setting plate adjusting means is provided below the setting plate. A control section calculates moved distance and stoppage position of golf ball based on the flying trace of golf ball sensed by the flying trace sensing means, and inputs signals reflecting the three-dimensional images of the golf course along the flying trace into the projector, so that the three-dimensional images are displayed on the projection screen. Also, the control section controls the setting plate adjusting means in accordance with the height and inclined angle of the stoppage position, so that the setting plate can be automatically adjusted to the height and inclined angle equal to those of the stoppage position. Therefore, a golfer can exercise golf in various inclined angles and topographical conditions like a real golf course.Type: ApplicationFiled: February 23, 2004Publication date: October 7, 2004Inventor: Oh Seok Kwon
