Abstract: A conveying apparatus with a first conveyor and a second conveyor is used a the welding apparatus and a welding method for container bodies and in particular can bodies between which conveyors the object to be welded is handed over. A control unit determines the take over position and/or the conveying travel of the second conveyor and controls the conveyors accordingly, so that the take over occurs at the determined position and/or with the determined conveying travel of the second conveyor. This allows an easy and swift changing of the welding apparatus to different sizes of the objects to be welded.

Abstract: The invention relates to a projection display having at least one light source and also regularly-disposed optical channels. The optical channels comprise at least one field lens, to which respectively one object structure to be imaged and also at least one projection lens are assigned. The distance of the projection lenses from the assigned object structures corresponds to the focal distance of the projection lenses whilst the distance of the object structures to be imaged from the assigned field lens is chosen such that a Köhler illumination of the assigned projection lens is made possible. Then the individual projections are superimposed to form the total image.

Abstract: In an embodiment, a method is provided for updating a computer program. In this method, a record related to a data structure being effected in the updating of the computer program is identified. Here, the data structure is accessible by the computer program. Additionally, a request is received during the update of the computer program to access a further record related to the data structure. The further record in the request is identified to match the record effected in the updating of the computer program.

Abstract: A device for the homogenization of radiation, preferably light, using chirped microlens arrays (cMLA) from the established regular microlens arrays (rMLA), chirped microlens arrays are an arrangement of non-identical lenses in one array. Non-identical means that the lens parameters of the lenses of the array, such as e.g. the radius of curvature, the free diameter, vertex position, and others, can vary from lens to lens or cell to cell. The parameters of each lens or cell can be determined by functions (analytically, numerically), the functions preferably being dependent upon the position of the cell or the lens in the array.

Abstract: During the bending of sheet metal sections (1, 2) for forming can bodies by means of a bending machine, the sheet metal characteristics of the individual sheets are measured, e.g. the thickness and/or the strength of the sheets. The measured value is used to control the bending machine (4). This permits a substantially constant bending result to be achieved, even with varying sheet metal characteristics.

Abstract: The invention relates to an arrangement for optically determining the distance of a reflecting surface that can be used, in particular, for determining slight variations in distance such as can frequently occur in vibrating systems. Such an arrangement can also be used as optical microphone or hydrophone. The arrangement according to the invention is designed in this case such that light from a light source is directed onto a reflecting surface via a first optical fiber, and light reflected therefrom is directed onto at least one statically arranged optical detector via the first optical fiber or at least one further optical fiber. An optical element collimating in the direction of the reflecting surface is arranged between the reflecting surface and the one or more optical fibers.

Abstract: An apparatus positions sheets preferably moving in a combination folding machine and defines a trailing edge range. A trailing edge of the sheet is to be positioned in a transport direction, depending on the dimensions of the sheet. The apparatus has positioning devices, by which the trailing edge can be positioned. The positioning devices are fixed to a carrier, and also a carrier actuating device is provided, by which the carrier can be moved by a predefined actuating travel in the transport direction of the sheets, so that the trailing edge is positioned within a trailing edge positioning range. The positioning devices are fixed to the carrier such that the respectively different trailing edge positioning ranges of the individual positioning devices in total cover the entire trailing edge range but each respective trailing edge positioning range is shorter in the transport direction than the trailing edge range.

Abstract: The invention relates to an illumination module for color display, preferably for use in data or video projectors as well as rear projection television sets, in which the light from at least three luminescent diodes (LEDs) or LED arrays of the base colors red, green and blue is collimated at a point provided for connection to a display unit and ranged on an optical axis of the illumination module.

For the purpose of color mixing, the LEDs and LED arrays of the other base colors are attached in such a way tat their beam paths (Lg, Lb) are laterally input in sequence under input angles (?, ?) of <90 degrees into the beam path (Lr) of the first base color.

Abstract: The present invention relates to a digital image recognition system having a minimum constructional length of less than one millimetre. The image recognition system hereby comprises a microlens array, a detector array and optionally a pinhole array. The mode of operation of this image recognition system is based on a separate imaging of different solid angle segments of the object space by means of a multiplicity of parallel optical channels. The optical axes of the individual optical channels thereby have different inclinations so that they represent a function of the distance of the optical channel from the centre of the side of the image recognition system orientated towards the image, as a result of which the ratio of the size of the field of view to the image field size can be determined specifically. Detectors are thereby used with such high sensitivity that the detectors have a large pitch with a small active surface area.
