Abstract: The invention relates to a method for the secured use of transportable data storage media in a closed network. The invention further relates to a transportable data storage medium comprising a rewritable memory for use in a closed network and to a closed network. The closed network (1) formed of at least two data processing devices (2, 3) is contactable by a transportable data storage medium (4). In order to allow data exchange between the closed network (1) and the transportable data storage medium (4) only when the transportable data storage medium (4) is also authorised for use, respective programs (7, 8, 9) are installed on both the data processing devices (2, 3) and the transportable data storage medium (4), by means of which programs an identification data set (7.1) stored on the transportable data storage medium (4) can be found, checked, transmitted, compared with a comparison data set (9.1) and can be replaced by a new identification data set (7.2).

Abstract: A method for efficiently handling e-mail traffic using an e-mail system includes sending an e-mail and a weighting and status table stored with the e-mail to a recipient. The weighting and status table includes a weighting, entered and selected by the sender, that pertains to the e-mail. An assessment of the weighting selected by the sender is received from the recipient of the e-mail. The assessment is entered into the weighting and status table as a statistical quantity so as to provide an updated weighting and status table. At least a diverging assessment is made available to the sender based on the updated weighting and status table. The previous weighting and status table is overwritten with the updated weighting and status table, which is provided to the sender for entering another weighting upon creation of a new e-mail for the same recipient.

Abstract: Laser protection arrangement with a safety cutoff comprising a passive laser protection wall which stores the radiation energy of impinging radiation of a laser of a laser material processing installation, a laser protection foil which causes a detectable change when struck by laser radiation and which is arranged in front in direction of the laser radiation, and at least one sensor which is connected to the laser by a threshold switch in order to switch off the laser when the received detector signal exceeds or falls below a threshold value.

Abstract: The present invention relates to a laser machining system with a protective enclosure wherein the protective enclosure is basically formed by a protective hood which encloses a workpiece that is mounted on a mounting device in such a manner that a laser head can be moved within the protective hood through the slit-shaped opening by means of a robot arm.

Abstract: The present invention relates to an adhesive security tape and to a method for its production. The adhesive security tape comprises first and second substrate layers that are connected to each other by means of a second adhesive layer and which can be attached by means of a first adhesive layer to an adhesive surface. The first substrate layer 2 has severing lines that completely penetrate at least part of the first substrate layer along the severing lines. The severing lines are preferably created with a laser beam, and the profile of the severing lines is designed so that the severing lines constitute an identifier.

Abstract: The aim of the invention is to provide positioning and mounting options with improved handling characteristics even at places that are difficult to access or in other difficult conditions. Said aim is achieved by using functional elements comprising at least one area that can be foamed by supply energy. At least one of said areas is used as a positioning element for positioning an object or for stiffening flexible or easily bendable materials in a shape-stabilizing manner.

Abstract: An arrangement for machining workpieces by a laser, particularly for cutting, perforating, notching, engraving, drilling and inscribing workpieces with three-dimensional structures of different sizes. The laser beam is directed to the workpiece, which is fixed on a holding device, by means of a robot-guided articulated mirror arm and a laser scanner. The laser beam is guided by a coordinated time-controlled and position-controlled deflection of the articulated mirror arm and of the mirror elements of the laser scanner.

Abstract: Procedure to produce a tear seam in thin sheets and thinly shaped pieces that are manufactured using a thermal shaping procedure, in which the surface shape is firmly applied to at least one side of the thin film or thinly shaped piece (hereafter called the outer side) by application onto the surface of a mold, and that the material is in a liquid state for a certain time, and that the tear seam is formed during the plastic phase.

Abstract: An airbag cover is defined by a predetermined breaking line which is introduced into a shaped flat material in a recessed manner. The recesses are achieved by removing material by means of laser radiation. According to the invention, the flat material is provided with a barrier layer. The barrier layer, by reason of its material properties, has greater resistance to removal of material by laser action than the material of the rest of the flat material. The recesses made by removing material extend along the predetermined breaking line in the flat material up to the barrier layer. The barrier layer makes it possible to produce a predetermined breaking line by means of laser machining which allows an exact residual wall thickness of the airbag cover in the area of the predetermined breaking line, so that the tearing strength can be adjusted very accurately, which is critically important for a reliable deployment of an airbag.
