359436000 | SCALE OR INDICIA READING | 6 |
20080231950 | Reading Machine with Camera Polarizer Layers - A reading machine includes an image input device including a lens and a polarizer disposed over the lens, a flash and a second polarizer disposed over the flash. The image input device also includes a computing device coupled to the image input device for capturing images, the computing device, including a processor to execute instructions and a computer program product residing on a computer readable medium, the computer program product comprising instructions for causing the processor to process the captured images to recognize features in the captured images. | 09-25-2008 |
20080266660 | Transparent meter register cover with integral light pipe - The invention provides a method and a transparent housing cover for a meter index for communicating optical signals through an optical port formed on a front face of the transparent housing cover, for further communicating optical signals in a straight line past one side of the meter index; and for re-directing the optical signals at an angle of approximately ninety degrees to or from an optical transceiver. The cover includes an integrally formed light pipe, the light pipe further forming the optical port near the front of the body and the light pipe extending along one side of the body and behind the meter index; and the light pipe includes a surface at a back end for reflecting light at approximately ninety degrees to and from a light transceiver positioned behind the meter index. | 10-30-2008 |
20110310477 | DISPLAY DEVICE FOR VEHICLE - A display device for a vehicle includes a front face cover that covers a front face of a display section for displaying information of the vehicle, and an antireflection film provided on a surface of the front face cover. The surface of the front face cover has a curved face which is formed so that an observation color of the curved face viewed from an eye range of a person sitting on a seat of the vehicle differs depending on an observation position in the eye range due to a difference in an interference wavelength of reflection light reflected by the antireflection film, the reflection light advancing toward the eye range from the front surface. | 12-22-2011 |
20160178807 | METHOD FOR FABRICATING A DISPLAY DIAL FOR A PORTABLE OBJECT SUCH AS A TIMEPIECE AND DISPLAY DIAL OBTAINED THEREBY | 06-23-2016 |
359437000 | Polarizer | 1 |
20100182685 | Combination Instrument - A combination instrument has a disk that is transparent for light in the visible range and that has a dial region and an indicator region. It further has a dial imprint, which is applied to the back of the transparent disk in the dial region. In addition, a polarizing filter disk is provided, which is disposed on the back of the transparent disk aligned with the indicator region and comprises a circular polarizing filter. An optical indicator unit is provided, which is disposed in alignment with the indicator region on the back of the transparent disk and the polarizing filter disk. | 07-22-2010 |
359440000 | Lens | 1 |
20080278803 | Dimensional Enhancement Lens - A lens for use with a display panel configured to emit light and display images is provided. The lens has a light-emitting surface and a plurality of enhancement portions. A first enhancement portion is configured to physically correspond to a first image displayed on the display screen. The first enhancement portion is further configured to collect at least a portion of the light emitted by the display screen and emit the light through the light-emitting surface of the lens. A second enhancement portion is configured to physically correspond to a second image displayed on the display screen. | 11-13-2008 |
