摘要:
A security element for securing valuable articles comprises an optically variable layer (18) that conveys different color impressions at different viewing angles, and a color-constant layer (17, 24). The optically variable layer (18) and the color-constant layer (17, 24) are stacked in a covering region (20), while at most one of the optically variable layer (18) and the color-constant layer (17, 24) is present outside (22) the covering region. The color impression of the stacked layers (18, 17, 24) in the covering region (20) and the color impression of the one layer (18) outside (22) the covering region are matched with each other when viewed at a predetermined viewing angle. Further, the color-constant layer comprises an ink layer (17) and a metal layer arranged below the ink layer (24).

The invention relates to a security element for security papers, bank notes, ID cards or the like, having at least one plastic layer on which at least two metal layers of different color are so disposed side by side and on the same side of the plastic layer that the different colors are visually checkable.
摘要:
A method for an emergency call from a vehicle to an alarm centre, including receiving a wireless initiation signal from a portable alarm unit, evaluating the initiation signal, and sending, based on the result of the evaluation, a wireless alarm signal from a vehicle communication system arranged in the vehicle to the alarm centre. If the owner of the vehicle or some other person gets into an emergency, for instance is assaulted, in the immediate surroundings of the vehicle, it is thus possible to send an alarm signal to an alarm centre via the vehicle without first entering it. The personal safety for the individual is therefore increased. In addition, in the case of an assault, the perpetrator can be frightened away by sound and/or light signals emitted by the vehicle.
摘要:
The present invention relates to a method for producing, for the depiction of a specified motif, a micro-optical depiction arrangement that exhibits a colored motif grid, composed of a plurality of micromotif elements, and a focusing element grid, composed of a plurality of microfocusing elements that reconstructs the specified motif when the micromotif elements are viewed.
摘要:
The invention relates to a method for encoding digital data, in particular of data processed in a microprocessor unit. In the method according to the invention for a respective data word (A, B, C) of a series of data words to be encoded subsequently a parity code (P(A), P(B), P(C)) is computed on the basis of the data of the respective data word (A, B, C). Further the respective data word (A, B, C) is altered with the aid of the data word (A, B, C) preceding it in the series, wherein the altered data word (Aa, Ba, Ca) and the parity code (P(A), P(B), P(C)) represent the encoded data word (Ac, Bc, Cc) and the encoded data word (Ac, Bc, Cc) can be decoded with the aid of the data word (A, B, C) preceding it in the series.
摘要:
A controllable valve is provided for a low-flammability fluid within an aircraft with at least one magnetic coil which, upon brief electrical excitation, moves a structural element provided therein from a first position to a second position in which the structural element is held by a permanent magnet after completion of the electrical excitation of the magnetic coil.
摘要:
Into a plastic card (1) of polycarbonate layers (10; 11; 12) there is laminated a security thread (3) by applying pressure and temperature, the security thread itself having a carrier foil (5) of polycarbonate and a coating (6) that is borne by the carrier foil and conveys holographic information. The connection of the polycarbonate carrier foil (5) of the security thread with the polycarbonate layer (10; 11; 12) of the data carrier adjoining said carrier foil takes place without using an adhesive or primer.
摘要:
An embossing foil (100) for transferring labels (2) to documents of value (1) includes at least a carrier foil (10), a label layer (20) and an adhesion promoter layer (30). The dimensions of the adhesion promoter layer (30) are limited to the contour of the labels (2) to be transferred from the embossing foil (100).
