  • Patent number: 10844229
    Abstract: Radiation-curable, polyester acrylate-containing compositions (I) obtainable by reacting 0.5 to 20 mol % of a polyester polyol (A) and 0.5 to 30 mol % of a polyester diol (B) with 1 to 10 mol % of phthalic anhydride (C) and 65 to 75 mol % of (meth)acrylic acid (D) in the presence of an acidic esterification catalyst, a hydrocarbon (L), and a polymerization inhibitor. Reaction temperatures range from 60 to 140° C. The hydrocarbon (L) functions as solvent, forms an azeotropic mixture with water, and is removed distillatively after esterification. Water formed in the reaction is removed azeotropically. After neutralization of the esterification catalyst, free (meth)acrylic acid is reacted with an epoxide compound (E) in an amount equivalent to the acid number of the reaction mixture. The compound (E) has at least two epoxide groups per molecule. The compositions are suitable for coating the surfaces of solid substrates.

  • Patent number: 8850239
    Abstract: The network computing cluster includes one or more network computing stations and one or more power autarkic network computing stations supplied by one or more associated local power generators. The power autarkic network computing stations and the local power generators are connected with a local power network. A control signal is sent to a resource managing unit of the network computing cluster via a communication network. The control signal indicates the ability of the power autarkic network computing stations to process IT-services. The resource managing unit receives the control signal via the communication network. Triggered by the control signal, the resource managing unit sends a signal for transferring an IT-service processed by a network computing station of the network computing stations to the network computing station via the communication network. The processed IT-service is transferred to one of the power autarkic network computing stations via the communication network.

  • Patent number: 8601564
    Abstract: The invention relates to a protection unit for protecting a packet-based network from attacks, comprising: a signature analyzer for analyzing a packet stream received in a security border node of the packet-based network and for detecting attacks by comparing signatures of the packet stream with a set of signatures of previously identified attacks, an anomaly detector for detecting anomalies in the packet stream, and a signature interference unit for updating the set of signatures when anomalies in the packet stream are detected, the updated set of signatures being subsequently used for performing the signature analysis. A distribution unit distributes at least one signature of the updated set of signatures to at least one further security border node of the packet-based network. The invention also relates to a security border node comprising such a protection unit, a network comprising at least two such protection units, and a corresponding protection method.

  • Patent number: 7860524
    Abstract: The invention concerns a method of providing a Push-to-Talk (=PTT) service within one or more telecommunication networks (1, 2, 3, 4) by means of a gateway-server (5) which sets up a virtual connection per PTT connection. The virtual connection provides information about the participating terminals (10, 20, 30, 40) of the PTT connection, the service type to reach each terminal (10, 20, 30, 40), and the connection status of each terminal (10, 20, 30, 40). Thus, the gateway-server (5) is capable of providing the PTT service within and/or across different telecommunication networks comprising radio access telecommunication networks (1), fixed wire-line telecommunication networks (2), circuit-switched telecommunication networks (3), and packet-switched telecommunication networks (4).

  • Patent number: 7756260
    Abstract: The invention concerns a method for providing features to the user of a telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) that is connected to a central unit (CU) whereby, if said telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) is currently not interconnected via the central unit (CU), said telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) notifies the central unit (CU) at least about certain kinds of user activities, in case of such notification the central unit (CU) checks whether it is currently interconnected to another telephone assigned to the same subscriber as said notifying telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) and in case of the existence of such interconnection, the notifying telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) is interconnected in parallel to this interconnection, and if said notifying telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) is not a telephone for digital communication, the other telephone is a telephone for digital communication.
