  • Publication number: 20100198621
    Abstract: A method, a mobile data medium and a system are disclosed for transferring medical findings data in configured form as configured data to a client. In at least one embodiment, findings data together with further data is configured here such that it is stored specifically for the respective application on a data medium as configured data. The configured data is created as a function of the analysis of a workflow and/or as a function of metadata relating to a patient examination. The configured data is written to the data medium.

  • Patent number: 7534318
    Abstract: A textured, layered mold-formed body is produced with a foil laminate in which a top foil of at most partially crosslinked polymer materials and a sub-foil containing a polymer foam material with a density between 35 and 120 grams per liter and a gel content of less than 80 percent are laminated together. The foil laminate is embossed with a texture and treated with electron beams to give the texture enough stability for a subsequent deep-drawing step in which the mold-formed body is produced.

  • Patent number: 7422240
    Abstract: A deformation device, especially for the steering column of a motor vehicle. The deformation device comprises a deformation tube (2), which can be deformed in a defined manner, as well as a deforming cone (1) associated with the deformation tube (2). The deformation device has at the deforming cone (1) at least one elevation (13, 28) or recess, whose edges (8) engage edges (9) of at least one impression (23, 25) or recess (10), whose shape corresponds to the elevation of the cone or the recess of the cone at the cone-side end of the deformation tube (2), in a positive (material blocking) manner, as a result of which essentially any desired high torque can be transmitted between the deformation tube (2) and the deforming cone (1) without any change in the good behavior in a collision.

  • Patent number: 6663738
    Abstract: A method for the preparation of a polyolefin foil by developing a foil from mass having a content of polyolefin and with subsequent treatment of the foil by an electron beams beam. The polyolefin foil prepare according to the invention specific method distinguishes itself vis-à-vis the state of the art by favorable price, concurrent with excellent ability of being laminated and embossed as well as having high grain stability.

  • Patent number: 6343812
    Abstract: A process is disclosed for fixing a motor vehicle steering column. The, motor vehicle steering column is adjustable in the axial and/or vertical direction and has a steering shaft and a housing accommodating the steering shaft, on a bracket of the steering column of the motor vehicle, which bracket is a rigid part of the body. In the case of an accident, a positive-locking connection is established by pyrotechnical device between the adjustable steering column housing and the bracket of the steering column, at the moment of the impact of the motor vehicle against an obstacle. A device for carrying about the above-mentioned process is disclosed, in which at least one pyrotechnical module and at least one element, which can be controlled by the pyrotechnical module, are present for the positive-locking connection between the steering column and the bracket, which is a rigid part of the body.
