20110164330 | METHOD AND ARRANGEMENT FOR REDUCING THERMAL EFFECTS IN COMPACT ADJUSTABLE OPTICAL LENSES - The present invention provides thermal compensation for a lens assembly comprising a polymer lens body. Polymers do have different thermal expansion coefficients which makes it necessary to compensate for thermal expansions to keep optical characteristics of such lenses within specifications when used under different environmental conditions. Also, it is necessary to provide thermal compensation during manufacturing of such lenses due to high temperatures during manufacturing steps. | 07-07-2011 |
20110158617 | DEVICE FOR PROVIDING STABILIZED IMAGES IN A HAND HELD CAMERA - Image stabilization devices and methods are disclosed. In various embodiments, image stabilization is achieved by altering the direction of the optical axis through a flexible lens body by activating actuators attached to the flexible lens body, wherein the amount of applied voltages onto the actuators are proportional to signals provided by motion sensors sensing yawing and pitching movements, respectively. | 06-30-2011 |
20110096411 | FLEXIBLE LENS ASSEMBLY WITH VARIABLE FOCAL LENGTH - The present invention is related to a lens assembly comprising a flexible lens body ( | 04-28-2011 |
20100182338 | DIFFRACTIVE TECHNOLOGY BASED METHOD AND SYSTEM FOR DYNAMIC CONTRAST MANIPULATION IN DISPLAY SYSTEMS - A method and system providing dynamic contrast control in scanning line color display systems, and particularly a method and system comprising at least two modulator units is disclosed. One modulator unit is for modulating pixel information in a line to be displayed while the other one provides illumination intensity control over different pixel areas or clusters of pixels of said same line to be displayed by using a tunable diffractive grating element (TDG) in the illumination path to provide image source dependent active brightness level control, i.e. ‘dynamic contrast’, as well as a shutter function for pixels off transition periods. | 07-22-2010 |
20100133230 | METHOD FOR MANUFACTURING ADJUSTABLE LENS - The present invention provides method steps for manufacturing an assembly of adjustable lenses on a wafer. The method steps provide an easy manufacturing of such lenses, minimizing the cost of assembly, and at the same time provide a solution for mass production of compact adjustable lenses for use in mobile phones, etc. | 06-03-2010 |
20100091389 | DESIGN OF COMPACT ADJUSTABLE LENS - The present invention provides a solution for designing a compact adjustable lens assembly, wherein a circular shaped piezoelectric crystal is bending a thin glass cover, thereby providing a shift of focal length of the lens assembly. | 04-15-2010 |
20090284666 | DUAL-LINE CHIP DESIGN OF LIGHT MODULATOR - Doubling the resolution of images in a line scan projection system is possible without doubling the length of the modulator or changing the size of the pixels. By arranging an additional pixel row in the modulator, and merging the rows together with half a pixel offset in both directions in the projected image, the resolution may be effectively doubled without significantly increasing the size or speed requirement for the modulator itself. | 11-19-2009 |
20090221765 | POLYMER FOR USE IN A TUNEABLE DIFFRACTION GRATING (TDG) MODULATOR - The present invention relates to a tuneable diffraction grating modulator based on the principle of total internal reflection comprising an elastomer as a deformable layer to be modulated in a nonuniform electric field. | 09-03-2009 |
