Abstract: The invention relates to a pressure sensor (1) comprising a pressure sensing arrangement (8) and a housing. The housing comprises an intermediate member (2) and a bottom part (3), wherein the intermediate member (2) comprises an aperture (4). The aperture (4) extends through the intermediate member (2), wherein the aperture (4) is on a first end (5) covered by a diaphragm (6) connected to the intermediate member (2). A second end (7) of the aperture (4) is covered by the bottom part (3) comprising the pressure sensing arrangement (8). Task of the invention is to provide a pressure sensor which allows a simplified and cost effective assembly and mounting. The task is solved in that the intermediate member (2) comprises a gripping surface (16) on an outer surface of the housing.

Abstract: The present invention relates to a maritime light source comprising a bottom housing and a lid attached thereto. The lid comprises an integrated lens portion and a button portion, wherein the lens portion is adapted to scatter light from an associated light source over an angle of at least 160 degrees in a substantially uniform manner. The button portion comprises an integrated and flexible push button membrane. A water proof sealing is formed between the bottom housing and the lid.

Abstract: A method and a system for improving the psychovisual experience of watching a display are presented. Measurements on the ambient light are performed by a sensor element, from which characteristics of the ambient light are derived. These are subsequently applied in a light-source adjustment model to determine the output of the light-source element. Moreover, a method and a system for adjusting the output of a light-source element by a feed-back loop involving the output from the light-source element and the input to a sensor element are revealed. In addition, the sensor element is also employed for adjusting the output of an electronic display by applying the results of the measurements to a preference model.

Abstract: The present invention relates to a method and corresponding system for improving the perceived visual quality of images for instance displayed on a color television screen. According to the invention, there is provided a means for carrying out histogram processing (13) for scaling an input video signal (6) such that the maximum dynamic range is utilised and where the quality of the perceived image is also optimised. According to the invention, the histogram processing (13) provides a transfer function for the image pixels to obtain enhanced image dynamics and also to provide a chrominance gain (gc) for scaling the chrominance components, when the luminance has been changed by the histogram processing. According to the invention, the histogram processing can also take variations of the ambient light into account (5).
