  • Patent number: 11931799
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a movable directed energy source to melt hardened metal drops and form an oxidation layer. A metal support structure can be formed over the oxidation layer, an object feature can be formed over the oxidation layer, or both a metal support structure and an object feature can be formed over oxidation layers located at opposite sides of a metal support structure. The oxidation layers weakly attach the metal support structure to the object feature supported by the metal support structure so the support structure can be easily removed after manufacture of the object is complete.

  • Patent number: 9330342
    Abstract: A system includes a pressure sensitive material that provides an indication of applied pressure for multiple locations on the material, and an analysis device in communication with the pressure sensitive material. The analysis device receives the indication of applied pressure, determines, for each of multiple measurement periods, a pressure image from the indication of applied pressure such that a sequence of pressure images is determined, and constructs a manifold representing the sequence of pressure images.

  • Patent number: 9106692
    Abstract: A system and a method for advanced malware analysis. The method filters incoming messages with a watch-list, the incoming messages including attachments, if an incoming message matches the watch-list, forwards the message to a malware detection engine, strips the attachments from the forwarded message, the one or more attachments including one or more executable files, launches a plurality of sandboxes, executes each of the executable files in the plurality of sandboxes, the sandboxes generating analysis results that may be used to determine whether each executable file is malicious, normalizes the analysis results, evaluates the risk level of the attachments to the forwarded message based on the normalized analysis results of the executable files in the attachments to the forwarded message, and, if the risk level of an attachment to the forwarded message is above a certain level, determines that the forwarded message is malicious and permanently quarantines the forwarded message.
