Abstract: The invention refers to a method and an apparatus for producing multi-level components with conform target density from powdered material. The powdered material is filled into a mould die, which includes a multiple of lower and upper relatively movable punches, and the filling height of the column over each punch is associated to the geometrical levels of the final component. The material is optionally pre-compacted by individual static pressure acting on each punch and is compressed by at least one shock or impact device from at least one direction. Compensating adjustments for powder flow between columns and for density gradients are made during the pre-compression and shock compression.

Abstract: A machine for producing a body with desired shape of a workable material through dynamic forging under impact and finally with energy retention while the shock wave fades out. The machine includes a machine stand, a dynamic outer impact system having an upper unit, and a lower impact unit, which includes a counter-impact device, and possibly one or more dynamic side impact units, and a static inner press system having an upper unit and a lower unit, possibly with additional one or more static side compacting units, with a central unit in between. The lower units of the outer and inner systems can be exchanged with a common stationary anvil for a single direction machine instead of a counter-acting machine.

Abstract: A method of producing a body from a particulate or solid material comprises filling a precompacting mould with the material, optionally vibrating the mould, pre-compacting the material and compressing it by at least one stroke with high kinetic energy in order to cause coalescence or high density of the material.

Abstract: An object (3) is imaged and, after image processing, an image is displayed on a head-mounted display (10) in front of the eyes of a user of the display. The display (10) is constructed with two display modules (13, 14) for displaying the image, designed to be positioned in front of each eye within a limited section of each eye's field of vision, the display modules being arranged each to show a separate image and being designed to leave the field of view free towards the surroundings at least downwards and to the sides of the user. The display modules (13, 14) are advantageously arranged to show two different images, one in front of each eye, so that the user experiences a stereoscopic image with a perception of depth in a part of his field of vision at a predetermined distance in front of his eyes.

Abstract: A method of producing a ceramic body by coalescence, wherein the method comprises the steps of a) filling a pre-compacting mould with ceramic material in the form of powder, pellets, grains and the like, b) pre-compacting the material at least once and c) compressing the material in a compression mould by at least one stroke, where a striking unit emits enough kinetic energy to form the body when striking the material inserted in the compression mould, causing coalescence of the material. A method of producing a ceramic body by coalescence, wherein the method comprises compressing material in the form of a solid ceramic body in a compression mould by at least one stroke, where a striking unit emits enough energy to cause coalescence of the material in the body. Products obtained by the inventive methods.

Abstract: A method of reducing noise in a video signal which includes a plurality of video frames being composed of a plurality of pixels, the method comprising the steps of: comparing video information contained in a current video frame and a plurality of temporally adjacent video frames; selecting from the current video frame and the adjacent video frames the video information that according to a predetermined condition is likely to be correct for the current video frame; and finally assigning the selected video information to the current video frame to thereby produce a video frame wherein noise has been reduced.

Abstract: An ignition transformer for gas discharge bulbs, or tubes, including a core, a primary coil, and a secondary coil. The transformer windings are wound axially along a rod-shaped core (1). The secondary winding includes two or more mutually concentric and axially extending windings (5, 6, 7), where each winding includes only one single layer. The primary winding (11) includes an axially extending winding that lies concentrically outside the outermost secondary winding (7).
