  • Publication number: 20150310212
    Abstract: The subject disclosure is directed towards running script through a malware detection system including an emulator environment to detect any malware within the script. Statistics are collected as part of processing the script, with parameterized heuristic analysis used to determine whether to run the emulation. The processing through the malware detection system may be iterative, to de-obfuscate layers of obfuscated malware. The emulator may be updated via signatures.

  • Patent number: 9102046
    Abstract: A hand tool impacting device may include a drive shaft, an impaler disk, and a floating pin positioned in an aperture of the drive shaft. Circular ramps along an outer edge of the impaler disk may interact with a stationary pin to translate the drive shaft and generate an impacting motion. A pair of springs placed against a side of the floating pin may allow a tool bit to engage or disengage the impaler disk, for selective use of translational impacting motion or rotational torque. An impact bit for engaging the impaler disk may include a tool head that may engage a work piece and a tool shaft inserted into the drive shaft to engage the floating pin.

  • Patent number: 8377010
    Abstract: A medical access device provides needleless access to patient fluid lines such as intravascular catheters. A retaining ring at the top end of the housing of the medical access device is molded around a septum that provides access for a tubular portion of a medical device such as a male luer taper of a syringe. Alternatively, the retaining ring may also be molded around the body or around both the body and the base of the housing. The molded retaining ring and septum are attached by mechanical attachment and/or chemical adhesion to minimize axial and rotational movement between the septum and the housing.

  • Patent number: 8219713
    Abstract: A network controller in a communication device may be operable to route local host-management traffic between a local host and a management controller within the communication device, wherein the local host may be operable to utilize its network processing resources and function during communication of the local host-management traffic. A dedicated management port may be configured in the network controller to enable receiving and/or transmitting local host-management traffic communicated from and/or to the local host separate from the local host's network traffic communicated via the network controller. The host-management traffic is communicated between the network controller and the management controller via NC-SI interface. The management controller may be assigned Internet protocol (IP) based addressing information for use during routing of local host-management traffic.
