The invention relates to a digital display device (10), comprising a display (12) for a scene (14), a means for displaying a virtual tool (18) for selecting at least one point (20) of the scene (14), and a touch-sensitive means for controlling said screen (12) coupled to the display means in order to move said virtual tool (18) on said scene (14). The virtual selection tool (18) includes at least one first display area (18A) for locating said point (20) on said scene (14), and a second display area (18B) for the touch-sensitive control of the movement of said tool (18) on said scene (14). The first (18A) and second (18B) display areas are separate and interconnected with one another.

The invention relates to a pressure sensor (10) that can both be easily calibrated and have a high measurement accuracy. The pressure sensor (10) comprises an elastically deformable membrane (1) that is fixed at the edge thereof and can be deflected on the basis of a pressure difference, and at least two deflection sensors, wherein the deflection sensors detect the deflection of surface regions of the membrane that are spaced differently with respect to the middle of the membrane. The pressure sensor comprises a calculating device which calculates a value for the pressure difference on the membrane out of a deflection in the middle of the membrane from the deflections detected by the deflection sensors.

The invention relates to a protective helmet (1) with a hard outer dome (2), an interior fitting (3), a foldable facial protection unit (4, 5) on the outer dome (2), and a camera unit (6) that is fastened onto the protective helmet (1). The facial protection device (4, 5) is coupled to a switching device (8), by means of which the camera unit (6) can be activated and/or deactivated.

The present invention relates to a method for producing a silico-alumino-phosphate, comprising the step of reacting a phosphorous source with a synthesis mixture having a template containing, aqueous-alkaline suspension of a SiO2-powder and an aluminum hydroxide powder at increased temperature, a silico-alumino-phosphate that can be obtained according to the method and that is doped with one or more transition metal(s) if applicable, and an associated catalytic compound and an associated catalyst molded body.

The invention relates to an image generation system for generating an image of a region of interest. The image generation system comprises a measured data providing unit for providing measured data of the region of interest, a reconstruction unit (12) for reconstructing a first and a second image of the region of interest from the measured data using a first and a second reconstruction method, a noise determination unit (13) for determining first and second noise values for first and second image elements of the first and second image, and an image element combining unit (14) for combining corresponding first and second image elements into combined image elements forming a combined image based on the first and second noise values. By combining corresponding image elements of two differently reconstructed images based on determined noise values, a combined image of a region of interest can be generated with an improved quality.

The invention relates to a force gauge (7) for isometrically measuring the muscle force of a person using a training device acting on the training device, wherein the training device comprises a plurality of weight bodies (6) for generating the training resistance, and a displaceably disposed weight bar (2), to which the weight bodies (6) can be releaseably connected, comprising a pin (8) in which at least one force gauge element (11) having at least one sensor area (H') is disposed. The sensor area (11) is thereby disposed on the outer side of the pin (8), and the pin (8) can be inserted into a corresponding opening (4) of the weight bar (2) implemented corresponding to the cross section of the pin (8). When the pin of the force gauge (7) is brought into contact with a fixed stop of the training device, the force applied by means of the weight bar (2) is detected isometrically, thereby also preventing the displacement or further displacement of the weight bar (2).
