The present embodiments relate to a particle therapy system having an accelerator unit for providing a particle beam and having a particle beam transport system for guiding the particle beam. The particle beam transport system has a first subarea by which the particle beam can be guided out from a level of the accelerator unit. A gantry-based radiation room is connected to the first subarea of the particle beam transport system. The present embodiments may also relate to a particle therapy system having foundations, where the foundations are dimensioned at one point such that a gantry-based radiation room can be retrofitted at the one point. In particular the foundations at the one point are located essentially at the same height as the foundations underneath an accelerator unit and/or underneath a particle beam transport system.

Method of scanning register marks produced in multicolor printing which includes generating signals by means of at least one photoelectric receiver from register marks which are applied, respectively, in one color, in a register mark track on a print carrier transportable past the receiver, the register marks differing sharply in contrast with the ink on the ink carrier, determining in a circuit arrangement amplitudes of the signals from the register marks, and bringing a filter arrangement into a radiation path between a light source and the receiver for contrast matching, further includes automatically bringing one defined color filter of the filter arrangement into the radiation path and, after scanning at least one group of register marks wherein all of the colors present in the print are contained, determining a scattering of intensity maxima of the signals generated from the register marks of the one group of register marks, the defined color filter automatically brought into the radiation path having a capability of producing a minimal scattering of the intensity maxima of signals generated by scanning register marks of at least another group of register marks succeeding the one group of register marks.

A method of activating a Multi-String inverter for photovoltaic generators (1a, 1b) of a photovoltaic plant (6), the Multi-String inverter incorporating on the input side a separate DC-DC converter (2a, 2b) for each generator string (photovoltaic generator) (1a, 1b) and each output of the DC-DC converters (2a, 2b) being connected in parallel and to an input of a DC-AC converter (3) and the DC-AC converter (3) being connected with an alternating current mains (4) for feeding into the mains aims at improving efficiency. This is achieved in that one or several electrical variables, namely input current, input voltage and/or input power are measured at each DC-DC converter (2a, 2b) and at least one of the DC-DC converters (2a, 2b) changing its operating condition as a is function of this measurement when a limit value and/or a range is exceeded in such a manner that its power loss is reduced so that the energy yield of the photovoltaic plant (6) is increased.
摘要:
A configuration for detecting a physical parameter at a stack of sheets resting on top of each other obtains signals from inside a stack in a wireless manner. At least one sensor that responds to changes in the parameter, is disposed between two sheets in the stack and is connected to a stationary evaluation unit. The sensor and the evaluation unit are connected by a wireless connection.
摘要:
A method for positioning a register mark sensor in a sheet printing machine, wherein a register mark sensor is moved in direction perpendicular to the direction of the movement of the sheet for detecting a register mark arrangement on the sheet, wherein the register mark sensor is moved until it is positioned in a defined scanning position relative to the register mark arrangement, the method of which includes the steps of: placing on the sheet a preliminary register mark, a given known distance A, perpendicular to the direction of the movement of the sheet, from a given register mark line, and after printing at least one sheet, positioning the preliminary mark sensor in relation to the preliminary mark.
摘要:
An image is recorded of the edge of a moving object, in particular a sheet, in a machine processing printing material. The illumination is carried out with an illuminating device, and an image is recorded of at least one part of the edge with an image recording device. The use of the illuminating device and/or the image recording device is substantially synchronous with the movement of the object and substantially parallel to the direction of movement of the object. A preferred illuminating device has a row or array of light sources which in each case are switched on and off synchronously with the movement of the object. The constant shadow or shadow strip produced by the illumination moves with the object and ensures adequate contrast between the brightly illuminated object and the dark background, so that the object can be segmented reliably, at least in the region of the edge, and its position, orientation and movement can be determined.

Data records contain identification data and user data and are either contained in a highest grouping level or are directly subordinate to precisely one data record group. Each data record group is either contained in the highest grouping level or is directly subordinate to precisely one data record group. Each data record group is in this way either empty or contains at least one directly subordinate element, which is either a data record group or a data record. A selection criterion is specified to a computer by a user, whereupon the computer displays to the user via a display device a list of at least the elements contained in the highest grouping level. The list is sorted according to an ordering criterion independent of the selection criterion. The identification data of each data record fulfilling the selection criterion and contained in the highest grouping level is displayed, and each data record group contained in the highest grouping level and to which at least one data record which fulfils the selection criterion is in turn directly or indirectly subordinate, is displayed. All other elements contained in the highest grouping level are not displayed. With regard to each displayed element, which is not contained in the highest grouping level, the data record group directly superordinate to the displayed element is displayed as well.
摘要:
A raster cutting apparatus and method for producing accurately formed, aspheric ophthalmic lenses having a good quality surface finish. The accurate form and good surface finish are obtained by using a substantially spherically shaped cutting tool having a large radius. The methods include utilizing a cutting path which provides substantially constant cutting-force, such as a constant surface-cutting-speed raster pattern.
摘要:
A color-matching apparatus for visual on-light evaluation of flexible copies includes a support for at least one copy having a supporting surface being concave as viewed by an observer. An areally radiating illumination configuration emits light of a defined type onto copies and generates a defined intensity of illumination in the supporting surface. The illumination configuration has a radiating surface being substantially convex, as viewed by the observer.
