  • Publication number: 20220297774
    Abstract: A track assembly mounted to a rotating wheel drive of a vehicle that includes a frame with inboard and outboard frame members having a center gap between them. A bearing housing is mounted to the outboard frame member. A hub adaptor has a peripheral wall forming a hollow interior that receives the wheel drive. Separate annular flanges are connected to and extend away from inner and outer surfaces of the peripheral wall and connect to the wheel drive and a sprocket surrounding the hub adaptor. As the hub adaptor rotates within the bearing housing, the sprocket rotates within the center gap of the frame. Idler are rotatably connected to opposed ends of the frame. An endless track is routed over the sprocket and around the idlers. The endless track engages with and is driven by rotation of the sprocket in order to circulate the track about the frame in a generally triangular path.

  • Patent number: 10677377
    Abstract: A conduit clip for use in a conduit clip arrangement together with a conduit includes: a ring member adapted to be placed around the conduit, the ring member having a through axis, a circumferential radially internal surface, and a circumferential radially external surface, the ring member comprising semi-circular ring portions connected by a living hinge. The circumferentially external surface has a circumferentially smooth envelope. Each side wall of the ring member is provided with a clamping device that cooperates with an attachment member. The circumferential radially internal surface has at least one upstanding projection configured to engage a groove in the conduit sheath when placed around it.

  • Patent number: 8392997
    Abstract: Among others, techniques and systems are disclosed for analyzing security threats associated with software and computer vulnerabilities. Stakeholder values relevant for a software system are identified. The identified stakeholder values are quantified using a quantitative decision making approach to prioritize vulnerabilities of the software system. A structured attack graph is generated to include the quantified stakeholder values to define a scalable framework to evaluate attack scenarios. The structured attack graph includes two or more nodes. Based on the generated structured attack graph, structured attack paths are identified with each attack path representing each attack scenario.
