Patent number: 7453596Abstract: A fully digital pulse width modulator substantially doubles resolution in a laser printer by outputting data to the laser on both the rising and falling edges of the clock cycle. A counter and the clock itself are used to select input to a multiplexer, and consequently, the data output to the laser from the multiplexer. A data selector code, generated by concatenating the binary value of the counter and the inverted clock bitwise, selects which of the 16 bits representing a pixel to place onto the data line, so that all 16 bits are output to the laser serially and sequentially in eight clock cycles. By using both the rising and falling edges of a clock cycle, the clock speed of the device is effectively doubled, without increasing actual clock speed. Device resolution is improved simply and inexpensively without major modification of printed circuit boards.Type: GrantFiled: December 13, 2005Date of Patent: November 18, 2008Assignee: Electronics for Imaging, Inc.Inventor: Marc Blumer

Patent number: 7453619Abstract: Disclosed herein is an optical delay line. The optical delay line includes a body and at least one wing, which constitute a rotating body that rotates around a rotational axis. The rotational wing includes a retroreflective curved surface, which is formed so that light can be vertically reflected by a reflective surface of the rotational wing. The retroreflective curved surface is formed so as to reversely reflect the light while varying an optical path difference at a predetermined speed when the rotating body rotates at a regular angular velocity. Thus, a long time delay value can be effectively generated.Type: GrantFiled: October 31, 2007Date of Patent: November 18, 2008Assignee: Korea Electrotechnology Research InstituteInventors: Geun Ju Kim, Yun Sik Jin, Seok Gy Jeon, Jung Il Kim
