  • Patent number: 11555843
    Abstract: A method for localizing a short circuit between a conductor and an electrically conductive shield of a high-voltage cable comprises providing at least two measuring apparatuses arranged at the high-voltage cable at a known distance from one another and having timers, synchronized with one another, and a measuring device for detecting an electric current flowing in the shield and/or an earthing line connecting the shield and earth. The measuring apparatus transmits pairs of current measurement values and associated values of the timer to an analysis unit, which, upon the occurrence of a current exceeding a threshold value and/or of a current profile over time that satisfies specific stipulations, feeds to a calculation unit the associated values of the timers and also an indication about the location of the measurement, for which first effects of the short circuit occurred.

  • Publication number: 20200329072
    Abstract: Aspects of the present disclosure involve utilizing network threat information to manage one or more security devices or policies of a communication network. The security system may receive threat intelligence data or information associated with potential threats to a communications network and process the threat intelligence data to determine one or more configurations to apply to security devices of a network. The system may then generate a rule or action to respond to the identified attack, such as a firewall rule for a firewall device to block traffic from the source of the attack. The threat intelligence information may include a confidence score indicating a calculated confidence in the identification of the malicious communications, which may be utilized by the system to determine the type of action taken on the security devices of the network in response to the information or data.

  • Publication number: 20070265781
    Abstract: A computer-implemented method for generating an image-textured digital surface model (DSM) for a geographical area of interest including both buildings and terrain may include using a computer to generate a digital elevation model (DEM) of both the buildings and terrain for the geographical area of interest. The method may further include providing a collection of optical images including oblique optical images for the geographical area of interest including both buildings and terrain. The computer may also be used to selectively superimpose oblique optical images from the collection of optical images onto the DEM of both the buildings and terrain for the geographical area of interest and to thereby generate the image-textured DSM for the geographical area of interest including both buildings and terrain.

  • Publication number: 20070195107
    Abstract: Images and video can be produced by compositing or alpha blending a group of image layers or video layers. Increasing resolution or the number of layers results in increased computational demands. As such, the available computational resources limit the images and videos that can be produced. A computational architecture in which the image layers are packetized and streamed through processors can be easily scaled so to handle many image layers and high resolutions. The image layers are packetized to produce packet streams. The packets in the streams are received, placed in queues, and processed. For alpha blending, ingress queues receive the packetized image layers which are then z sorted and sent to egress queues. The egress queue packets are alpha blended to produce an output image or video.

  • Patent number: 6250565
    Abstract: A toy sprinkler with the appearance of an amusing figure or creature with appendages that simulate movement of the appendages of the figure or creature. Liquid carrying conduits extending along appendages of the figure cause the appendages to move either in a planar path when liquid at low pressure passes through the conduits, or randomly when liquid at high pressure passes through the conduits.
