摘要:
Memory device having a memory for storage of data to be shifted, as well as a unit for encryption of data based on an asymmetric encryption method using a public key of a second memory device, to which the data which is to be shifted and is stored in the memory is to be shifted. In addition, a deletion unit is provided for deletion from the memory of the stored data which is to be shifted, once the data which is to be shifted and is encrypted with the public cryptographic key of the second memory device has been formed. A copying unit copies the shift message to the second memory device or to a third memory device, with the data no longer being available in the first memory from a time before the copying of the shift message to the second memory device or to the third memory device.
摘要:
A communication conference including at least one unambiguously identifiable conference media data flow. The access right within the communication conference is assigned by taking into consideration the conference media data flow.
摘要:
Communications right allocation information is additionally contained within a telecommunications conference control message, the allocation information specifying an event on whose occurrence a communications right is withdrawn from or allocated to the telecommunications terminal within the scope of the telecommunications conference.
摘要:
A method for processing digital media content in a mobile device, wherein the digital media content is protected using digital rights management, wherein a digital rights protection removing unit is assigned to the protected digital media content and which digital rights protection removing unit is used to remove the protection from the protected digital media content. The method includes the steps of receiving a presentation request for presenting stored digital media content, retrieving the digital rights protection removing unit from a memory card of a mobile device or from a User Identity Module unit of a mobile device, verifying that the digital rights protection removing unit allows removal of the protection from the protected digital media content, and removing the protection from the protected digital media content using the digital rights protection removing unit, thereby generating unprotected digital media content for presentation using the mobile device.
摘要:
Media data from a first communication session and media data from a second communication session are received by a unit in the communication network and are combined therein to form at least one combined media data stream which contains the media data from the two communication sessions. The combined media data stream is sent to the communication terminal.
摘要:
A voting message which includes a voting question is coded in accordance with a transport-protocol control protocol, for example in accordance with the real-time transport control protocol, and is sent in the course of a conference, in order to initiate a voting.
摘要:
A dual-mass flywheel includes a primary-side first sheet-metal shaped part configured to be fastened centrically with respect to an axis of rotation. The primary-side first sheet-metal shaped part contributes to a primary mass. A secondary-side second sheet-metal shaped part is mounted rotatably about the axis of rotation in relation to the primary-side first sheet-metal shaped part. The second sheet-metal shaped part contributes to a secondary mass. A torsion damper device connects the primary-side first sheet-metal shaped part and the secondary-side second sheet-metal shaped part to one another in a torsionally elastic manner. A mass ring with a large diameter contributes to the secondary mass. A sheet metal element connects the mass ring directly to the secondary-side second sheet-metal shaped part at a small diameter.
摘要:
The invention relates to biocidal polymers based on guanidine salts characterized in that they are representatives of a number of polyoxyalkylene guanidines and their salts and are a product of a polycondensation of guanidine salts with diamines which include two amino groups and polyoxyalkylene chains therebetween.In addition to a high bactericidity, these new polymer products are provided with a relatively low toxicity, an increased hydrophily, a quick and complete dilution in water, increased values of relative molar mass, and distinct characteristics of polymer surface active substances.
摘要:
What is described is a structural part comprising a mounting surface (M) for mounting the mounting surface to an attachment surface, wherein means for adhesive-bonding the mounting surface (M) with the attachment surface are provided, in order to glue the structural part to the attachment surface, and wherein spacers are provided on the mounting surface (M), said spacers causing a predetermined gap (S) between the mounting surface (M) and the attachment surface when attaching the structural part to the attachment surface and being removable and/or deformable by pressing the structural part onto the attachment surface.
摘要:
A reactor for the thermal cleavage of monofunctional and/or polyfunctional carbamic esters into the corresponding isocyanate and hydroxyl components in the liquid phase having devices for introduction of heat into the reactor, where the devices are heat exchanger plates through which a heat transfer medium flows and have a geometry defined by the ratio of the degassing area to the volume and arrangement of the heating surfaces which makes it possible for the cleavage to be carried out in a two-phase mixture which has a gas content of over 50% by volume.
