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.

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.

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.

Abstract: A system (10) for automatically inspecting a stream of matter (12) for varying composition, comprising an emitting device (16) serving to emit a detection medium, which comprises electromagnetic radiation of a substantially constant intensity, to an irradiated zone (I) of the stream at which the medium penetrates a surface of the matter (12), the irradiated zone (I) extending continuously across substantially the width of the stream, the medium penetrating the surface being varied by the matter (12), a receiving device (32) for receiving the varied medium emanating from the matter (12) at a detection zone (D) substantially separate from the irradiated zone (I), and a detecting device (34) serving to generate detection data in dependence upon the varied medium, the arrangement being such that, in use of the system (10), at least the majority of the varied medium received at the receiving device (32) can be transflected medium.

Abstract: A device and a method for detection of characteristic features of a medium that is wholly or partly transparent, wherein said medium is placeable in an observation area in a light path extending between a light source and a light detector, wherein said medium is illuminated by the light source in the observation area, wherein at least one light-directing optical element is arranged in connection with the observation area. Light transmitted through said medium, which is deflected by said medium when it is in said area and thus causes a change of light direction in said area, is detected. Characteristics of said medium are determined by spectrometry of the received light-deflected light, and a wavelength-sensitive element is used at a position in the light path, either at or as a part of the light source or the light detector.

Abstract: Apparatus and method for optical inspection of a pipeline (2) for transporting fluid (3) by internal surveying. Light source means (4) are adapted to form one or more beams of light (5) illuminating a line (L) of a surface part (9) of said pipeline (2). Optical receiving means (6) are positioned outside a plane formed by said beams (5) and arranged to have in its field of view (7) the line (L) formed on the internal wall of the pipeline (2) by the beam (5). The receiving means (6) are adapted to form a two-dimensional indexed images (20k) each comprising intensity data for a predetermined number of pixels in each of a predetermined number of lines (M) of said image (20). A data processing unit (100) including an image analyzer module (110) is adapted for extracting a depth profile of said surface (9).
