Abstract: A host computer system can be monitored to track its system performance data with respect to internal system parameters, and this monitoring can be performed when the host computer system is known to be under a cyberattack and when it is known to not be under the cyberattack. The system performance data for the host in these conditions can be comparatively analyzed by host level data analytics to find a subset of the internal system parameters and their corresponding data values that discriminatively correlate to the cyberattack. From this information, a cyberattack signature can be generated. The host system can thereafter be monitored based on its system performance data to determine whether this system performance data matches the cyberattack signature to support determinations as to whether the host is under cyberattack.

Abstract: A chain lock has a chain engagement portion including a slot configured to allow a link of the chain to pass therethrough with the chain engagement portion engaging an adjacent link of the chain. The chain lock has a pivoting member with a proximal and distal end. The pivoting member pivots about the proximal end such that the distal end is movable between a first position in which the pivoting member distal end is spaced from the slot in a manner to allow a chain to be received in and removed from the slot and a second position in which the pivoting member distal end extends across the slot to prevent the chain from being received in and removed from the slot. The pivoting member has a pivot axis spaced from and parallel to the chain engagement portion.

Abstract: The method improves the signal-to-clutter ratio of an airborne earth penetrating radar for distinguishing subsurface objects from surface clutter or above-ground objects. The method relies on the dispersive response of the signals returned from an subsurface object to distinguish these subsurface signals from the non-dispersive response signals returned by surface clutter. The electromagnetic response from a subsurface object is spread out over time in comparison to the response from surface clutter. A correlation coincidence detection methodology discriminates surface clutter based on the temporal persistence of a subsurface object. The correlation procedure produces a sequence of values which are used as the basis for detection. If the radar pulses detect a subsurface object, the sequence of values persists beyond the interval of integration containing the clutter response.
