  • Method for manufacturing adjustable lens
    Patent number: 8883019
    Abstract: 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.

  • Flexible lens assembly with variable focal length
    Patent number: 8390939
    Abstract: The present invention is related to a lens assembly comprising a flexible lens body (10) inside a cavity bounded by a sidewall (11) and a first transparent cover (13), and a second transparent cover (14), wherein both covers (13,14) are in contact with respective surfaces of the lens body (10). Piezo electric elements (12) shapes the lens body (10) when activated, thereby adjusting the focal length of the lens assembly.

  • Compact adjustable lens
    Patent number: 8045280
    Abstract: 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.

  • Sensor element especially for pressure sensors
    Patent number: 6595063
    Abstract: A system and corresponding method for bulge testing films (e.g. thin films, coatings, layers, etc.) is provided, as well as membrane structures for use in bulge testing and improved methods of manufacturing same so that resulting membrane structures have substantially identical known geometric and responsive characteristics. Arrayed membrane structures, and corresponding methods, are provided in certain embodiments which enable bulge testing of a film(s) over a relatively large surface area via a plurality of different free-standing membrane portions. Improved measurements of film bulging or deflection are obtained by measuring deflection of a center point of a film, relative to non-deflected peripheral points on the film being tested. Furthermore, membrane structures are adhered to mounting structure in an improved manner, and opaque coatings may be applied over top of film(s) to be bulge tested so that a corresponding optical transducer can more easily detect film deflection/bulging.
