  • Publication number: 20120218902
    Abstract: The present invention provides a complete virtual multi-vendor EMS based network that behaves identical to the network elements of the EMS clients. A virtual network simulator is built that has the ability to faithfully simulate the behavior of any vendor's EMS to represent the data objects required by the TMF 814 specification. This allows automatic provisioning and maintenance of the Operation Support Systems to fully test new functionality against complete EMS based network without depending upon the availability of any physical equipment, thereby providing much quicker, low cost, extremely life-like testing environment.

  • Patent number: 8155097
    Abstract: A system and method for predicting future interference power in packet-switched networks is disclosed, allowing improved performance in such networks via optimized link adaptation and power control. In an embodiment for use in a cellular network, Kalman filtering can be used to provide the interference estimation through identification of the number of active co-channel interferers in the cellular networks and correlation of the interference power with the number of active interferers. A two-dimensional Kalman filter can be used to exploit that correlation to enhance prediction accuracy. In an alternative embodiment, a one-dimensional Kalman filter can be used where the number of active interferers is not considered.

  • Patent number: 8092914
    Abstract: A heat sink substrate has a composite structure including a three-dimensional network structure of SiC ceramic having pores infiltrated with Si, and has a thermal conductivity of not less than 150 W/m·K and an oxygen content of not greater than 7 ppm. The heat sink substrate is easily allowed to have an increased surface area. Further, the heat sink substrate has a higher thermal conductivity and a coefficient thermal expansion close to that of the SiC. Therefore, the heat sink substrate is superior in the efficiency of heat conduction from a semiconductor device. The heat sink substrate is produced by infiltrating a thermally melted Si into the pores of the three-dimensional network structure in a non-oxidative atmosphere in the presence of an oxygen absorber.

  • Patent number: 8046577
    Abstract: A protocol framework for a Secure IP Access (SIA) method, and supporting components deployed on IP hosts and IP networks. Using this method, an IP host can establish a secure data channel within an IP network over an insecure shared link while requesting IP address and networking configuration parameters from the IP network. A system administrator can implement strong access control against various attacks that an edge IP network may have to face, such as a denial-of-service attack that exhausts assignable IP addresses. This is a lightweight, scalable, and backward-compatible solution that can improve security performance for public and corporate LANs having open access such as wireless access points and Ethernet jacks.

  • Publication number: 20110175922
    Abstract: A system and a computer-readable medium are provided for controlling a computing device to define a set of computer animation parameters for an object to be animated electronically. An electronic reference model of the object to be animated is obtained. The reference model is altered to form a modified model corresponding to a first animation parameter. Physical differences between the electronic reference model and the modified model are determined and a representation of the physical differences are stored as the first animation parameter. Altering of the reference model and determining of the physical differences are repeated. The stored parameters are provided to a rendering device for generation of the animation in accordance with the stored parameters. Determining physical differences between the electronic reference model and the modified model and storing a representation of the physical differences as the first animation parameter include comparing vertex positions of the reference model.
