  • Publication number: 20170100263
    Abstract: The invention relates to a method for producing an artificial foot, comprising a medial plane (M) in a longitudinal axis, in which a nominal foot length (1) is defined as a distance from a heel to a foot tip of a natural foot replaced by the artificial foot, and designed having a top side connecting piece (4) for torsionally rigidly connecting a foot insert (2) extending substantially over the length of the foot (1), and contacting two contact surfaces (6, 7) over the length (1), of which a first heel side contact surface (7) is located in the heel area and a second hall side contact surface (6) is located in the hall area, and designed so that the connecting part (4) is connected to the contact surfaces (6,7) of the foot part by means of spring connections.

  • Patent number: 9498352
    Abstract: The invention relates to a method for producing an artificial foot, comprising a medial plane (M) in a longitudinal axis, in which a nominal foot length (l) is defined as a distance from a heel to a foot tip of a natural foot replaced by the artificial foot, and designed having a top side connecting piece (4) for torsionally rigidly connecting a foot insert (2) extending substantially over the length of the foot (l), and contacting two contact surfaces (6, 7) over the length (l), of which a first heel side contact surface (7) is located in the heel area and a second ball side contact surface (6) is located in the ball area, and designed so that the connecting part (4) is connected to the contact surfaces (6, 7) of the foot part by means of spring connections.

  • Patent number: 7426183
    Abstract: The invention relates to a method for determining the load in a communication network provided with network elements such as internal nodes and links and with access nodes, respectively comprising an input node and an output node, which derive and transfer data packets from connected terminals and/or other networks. The internal nodes and links from paths according to routing algorithms and the internal nodes provide data packets with a load-dependent marking. According to the invention, the output nodes separately count up the data packets arriving from the communication network and the markings contained therein according to paths, deriving therefrom a value for the relative load along the respective path, and the values derived from all output nodes are introduced as parameters into system of equations describing the communication network with the internal nodes access nodes, whereby the solution thereof results in a determined relative network element load.

  • Publication number: 20050083951
    Abstract: The invention concerns a method for determining the load in a communication network (1) provided with network elements such as internal nodes (5, 6, 9) and links (10, 11, 12) and with access nodes (2, 3, 4), respectively, comprising an input node (21, 31, 41) and an output node (22, 32, 42), which derive and transfer data packets from connected terminals and/or other networks. The internal nodes and links form paths according to routing algorithms and the internal nodes provide data packets with a load-dependent marking (M).

  • Publication number: 20050033859
    Abstract: In a method for access control to a communications network with internal nodes and access nodes whereby each of the access nodes consists of an ingress node and an egress node, and which sends and receives data packets from connected equipment and/or other networks whereby the internal nodes using routing algorithms direct the data packets from an ingress node to an egress node, and whereby the internal nodes provide data packets with a load-dependent mark, it is provided that the egress nodes count the data packets and the marks contained therein arriving from the communications network separately by ingress node, and thereby form load reports from the particular time interval during which the counting occurs, and that data for access control are derived from the load reports.
