摘要:
Described is a multi-layer body (11, 12) having a replication lacquer layer (22). A first relief structure (25, 125, 65) is shaped into the replication lacquer layer (22) in a first region of the multi-layer body in a plane defined by co-ordinate axes x and y and an electrically conductive coating (23l, 23n, 123n) of a constant surface density is applied to the replication lacquer layer (22) in the first region of the multi-layer body (11, 12) and in an adjacent second region of the multi-layer body (11, 12). The first relief structure (25, 125, 65) is a structure with a high depth-to-width ratio in respect of the individual structure elements, in particular with a depth-to-width ratio>2. At least one perpendicular or almost perpendicular flank extends over the entire or almost the entire depth of the relief structure, the flank in that way reducing or suppressing electrical conductivity of the coating.

The invention concerns a security element (11) in the form of a multi-layer film body, a security document having such a security element and a process for the production of such a security element. The film body on a carrier film (10) has a release layer (20), a protective lacquer layer (21), a replication lacquer layer (22) with relief structures (25, 26), a metal layer (23) and an adhesive layer (24). A first relief structure (25) has a depth-to-width ratio of >0.5, whereby the metal layer (23) is more transparent in the region of the first relief structure (25). A second relief structure (26) has a low depth-to-width ratio whereby the metal layer (23) is less transparent or is opaque in the region of the second relief structure (26).
摘要:
In a method for controlling the acquisition and/or evaluation operation of image data in medical examinations, using a statistical model of the target volume based on data about real anatomy, spatial information (in particular position, orientation and shape) of the target volume are automatically determined in a previously-acquired planning image data set wholly or partially showing a target volume, and the acquisition and/or evaluation operation is controlled using the spatial information.
摘要:
A method and apparatus for mapping a texture to a surface of a computer generated object dependent upon the geometric shape of the object. The method includes the steps of approximating a true pixel color by performing a number of texturing operations and averaging the results of the texturing operations. The apparatus including a texturing unit comprising a control unit for determining a set of N footprint textel locations, a RAM for determining N sets of textel values with each set of textel values being associated with one footprint textel location, an interpolator for interpolating the N sets of textel values for each textel location, and an averaging unit for determining an average value from the interpolated values for each textel location.
摘要:
A layer arrangement is proposed, particularly for transfer films or laminated films, which exhibits at least two superposed synthetic resin layers, between which there is provided an interface surface having a refractive structure producing a lens-like effect, the novelty claimed being a special design of the structure having a diffractive effect.

In order to improve target illumination, a light source (2) of an emitter, which has a laser diode (3) configured as an edge emitter with a wavelength of 1,550 nm, has beam forming optics (4) mounted downstream in relation thereto, which comprise a cylindrical lens (7) and a first deflection element (8) with three fields having different diffraction structures. Said deflection element are located next to one another and crosswise in relation to the first fields and which also have different diffraction structures. Said deflection element directs the partial beams to the aperture of a collimator (1) in such a way that the partial beams substantially fill said aperture. The first deflection element (8) and a mount (6) for the cylindrical lens (7) are integral and, alike the second deflection element (10), are made of plastic. Both parts are glued to opposite sides of the frontal areas of a block (5) made of glass.
摘要:
In the method according to at least one embodiment of the invention, a first segmentation of a structure in an image data record is firstly carried out, and a first final segmentation result is obtained therefrom. A region in the image data record is selected based on the first final segmentation result obtained. A first band is placed at a first, outwardly pointing distance from the selected region. This first band characterizes a background region. A second band is placed at a second, inwardly pointing distance from the projected first final segmentation result of the first segmentation. This second band characterizes a structure region. A further segmentation is carried out based on the characterized background region and the characterized structure region, and the final segmentation result of the further segmentation is saved and/or displayed. Furthermore, an image processing unit for carrying out the method is disclosed.
摘要:
The invention concerns a film, in particular a stamping film, laminating film or sticker film, which has at least one anisotropic polymer layer of an at least partially oriented liquid crystal material. The anisotropic polymer layer has one or more first regions which form a first security feature and in which the anisotropic polymer layer has properties which linearly polarise or which rotate the direction of rotation, and one or more second regions which form a second security element and in which the anisotropic polymer layer has circularly polarising properties. The first security feature is visualised when viewed through a first polariser and the second security feature is visualised when viewed through a second polariser responsive to a different polarisation state from that of the first polariser.
