  • Crash attenuation system for aircraft
    Patent number: 7954752
    Abstract: A crash attenuation system for an aircraft, the system having an airbag carried by the aircraft and inflatable generally adjacent an exterior of the aircraft. The airbag has at least one vent for releasing gas from the interior of the airbag. A first gas source is in fluid communication with the interior of the airbag for inflating the airbag with gas generated provided by the first gas source. A vent valve is provided for controlling a flow of gas through each vent, each vent valve being selectively configurable between an open state, in which gas can pass through the associated vent from the interior of the airbag, and a closed state, in which gas is retained within the interior of the airbag. A second gas source is provided for at least partially re-inflating the airbag after venting of gas through the at least one vent.

  • HYDROCARBON CONVERSION PROCESS
    Publication number: 20110123406
    Abstract: A process is provided to produce an ultra low sulfur diesel with less than about 10 ppm sulfur using a two-phase or liquid-phase continuous reaction zone to convert a diesel boiling range distillate preferably obtained from a mild hydrocracking unit. In one aspect, the diesel boiling range distillate is introduced once-through to the liquid-phase continuous reaction zone over-saturated with hydrogen in an amount effective so that the liquid phase remains substantially saturated with hydrogen throughout the reaction zone as the reactions proceed.

  • Method and system for the assignment of security group information using a proxy
    Patent number: 7840708
    Abstract: A method and system for the assignment of security group information using a proxy is disclosed. The method includes receiving an address of a network device at a first network device, receiving a security group of the network device at the first network device and associating the address information and the security group information with one another at the first network device. The first network device is coupled to a second network device. The address is represented by address information, which is received from the second network device. The security group is identified using the security group information, which indicates the network device is a member of the security group. The address information and the security group information are associated with one another by storing the address information and the security group information at the first network device.

  • Distributed forwarding in virtual network devices
    Patent number: 7839843
    Abstract: A virtual network device sub-unit includes an interface to a virtual network device link and a distributed forwarding module. The interface receives a packet, and the distributed forwarding module forwards the packet received by the interface. The distributed forwarding module performs an ingress lookup if the packet includes a multicast destination address and an egress lookup if the packet includes a unicast destination address. If the packet includes a multicast destination address, the distributed forwarding module replicates the packet for each of several outgoing VLANs associated with the multicast destination address. If an additional multicast packet is received via an interface that is not coupled to a virtual network device link, the distributed forwarding module sends at most one copy of the additional multicast packet via the virtual network device link.

  • NETWORK TRAFFIC RATE LIMITING SYSTEM AND METHOD
    Publication number: 20100287303
    Abstract: A system and method is provided for rate limiting network traffic flow of an untrusted application. A master module in a server environment manages network traffic flow restrictions. A slave module executes client applications in the server environment. A services module in the server environment executes a trusted application to validate the client application to the master module. A traffic restriction module on the master module sets network traffic restrictions when validation has not been received for the client application on the slave blade, and receives client application validations from the trusted application to unrestrict network traffic flow for the client application on the slave blade.

  • Soft in-plane tiltrotor hub
    Patent number: 7828525
    Abstract: A rotor hub assembly for a rotary-wing aircraft has a central member and a plurality of blade grips adapted for attaching rotor blades to the central member. The blade grips are pivotally attached to the central member and are capable of pivoting about a pivot axis generally normal to a plane of rotation of the blades. The pivoting allows for in-plane motion of the blades relative to the central member. A damper is operably connected to each blade grip for damping the in-plane motion of the associated blade, each damper being selectively switchable between at least two spring rates.
