US07841008B1 Threat personalization
A determination is made as to whether there is a correlation between a user's security risk profile and a personalized threat profile of an actual or spreading threat. If there is a correlation, a personalized reactive alert is issued in the case of an actual threat. The personalized reactive alert informs the user of specific suspected data that may have been compromised by the threat and the specific non-computer related action that the user should take. Further, if there is a correlation, a personalized proactive alert is issued and/or personalized proactive protective action taken in the case of a spreading threat. The personalized proactive alert informs the user of the spreading threat that the user and/or the user's host computer system is particularly susceptible to. Further, the personalized proactive protective action taken provides automated risk mitigation.

US07839769B2 Method for the organization of network nodes in a packet-switched network
There is described a method to organize a network, wherein if for a first router set up as the default gateway an inaccessibility of an assigned network element is detected at an interface of the first router a second router is set up as the logical default gateway. In this case a provision is made such that in the course of setting up the second router as the default gateway a check on the interface metric is performed at the first and/or second router and that in consequence of the inaccessibility detected for the interface an adaptation of the interface metric is carried out. The interface metric is propagated for example by way of the routing protocol OSPF and/or EIGRP and/or IS-IS to other routers. When using the method it is possible in a failure scenario with divided Layer-2 networks to avoid an occurrence of “black holes”, in other words gaps in communication. Moreover asymmetric routing, which is caused by a changeover of the logical gateway from the first router to the second router, can be eliminated. The danger of an excessive exchange of unicast messages, which can result in a high failure level of all participating network nodes and network node elements, is thus also excluded.

The sign of each offset error, i.e., sign (Xk−Xmean), is then used to drive an adaptive algorithm whose output represents an offset correction value for the corresponding ADC. The offset, gain, and phase correction outputs from the adaptive algorithm is fed to an array of Digital-to-Analog converters (DACs) whose outputs are voltages or currents that directly or indirectly controls the offset, gain or phase setting of each individual ADC.
