Publication number: 20070171386Abstract: A projector comprises a light-emitting device for generating light beams, a reflector for focusing the light beams to a predetermined region, a light integrator positioned at the predetermined region and a brightness-adjusting module for adjusting the brightness of the projector by changing the relative distance of the reflector and the light integrator. Preferably, the reflector is an elliptical reflector having two foci, the light-emitting device is positioned at one of the two foci and the other focus is laid in the predetermined region. The present method for adjusting the brightness of a projector is characterized in adjusting the distance between the light integrator and the reflector to adjust the brightness of the projector.Type: ApplicationFiled: March 24, 2006Publication date: July 26, 2007Applicant: LUMENS DIGITAL OPTICS INC.Inventors: Wen Chin Cheng, Han Chung Chang

Publication number: 20070171393Abstract: A laser straight ruler having a main body and a beam scanner installed on the main body. A laser beam is scanned to form a beam spot on an object. A position sensing device receives a laser beam reflected by the object and senses a position of the beam spot. A signal processing unit drives the beam scanner and processes a signal of the position sensing device. A display displays a change in a distance between the main body and the object and data including a measured distance value from the signal processing unit. An input portion inputs data including adjustment of a scanning width of the beam spot and sets start and end positions of the measured distance. A straight distance of the object is measured or the beam spot having a scanning width corresponding to a measured distance or a predetermined distance is projected to the object.Type: ApplicationFiled: June 30, 2006Publication date: July 26, 2007Inventors: Young-chul Cho, Seok-mo Chang
