  • Patent number: 9774628
    Abstract: An aircraft includes an aircraft network having nodes and links and a sandbox network in communication with the aircraft network. The sandbox network simulates the aircraft network and includes sandbox nodes corresponding to the nodes of the aircraft network, a first set of sandbox links corresponding to the links of the aircraft network, and a second set of sandbox links providing communication between sandbox nodes not in communication via the first set of sandbox links. Computer executable instructions, when executed, perform the steps of: generating network traffic over the sandbox network such that the sandbox network models a behavior of the aircraft network; identifying a suspicious activity on the aircraft network; routing the suspicious activity from the aircraft network to the sandbox network; and analyzing the suspicious activity as the suspicious activity traverses through the sandbox network.

  • Publication number: 20040204450
    Abstract: Quinoline and quinoxaline compounds, pharmaceutical compositions containing such compounds and the use of such compounds to elevate certain plasma lipid levels, including high density lipoprotein-cholesterol and to lower certain other plasma lipid levels, such as LDL-cholesterol and triglycerides and accordingly to treat diseases which are exacerbated by low levels of HDL cholesterol and/or high levels of LDL-cholesterol and triglycerides, such as atherosclerosis and cardiovascular diseases in some mammals, including humans.
