Abstract: Providing a risk analysis report for an undesired event includes receiving a request comprising undesired event data defining an undesired event, wherein the undesired event data corresponds to an asset, identifying, from an attack database, one or more sets of attack attributes related to the undesired event data, and identifying one or more protection measures relevant to the asset and the attack attributes. The technique also includes performing a first set of Monte Carlo simulations for the undesired event based on combinations of the attack attributes, the protection measures, and the asset, and performing a second set of Monte Carlo simulations for the undesired event based on a subset of the combinations of the attack attribute. One or more combinations of the attack attributes, the protection measures, and the asset which result in the undesired event are provided in accordance with outcomes.

Abstract: Providing a risk analysis report for an undesired event may include identifying an attack type resulting in the undesired event and at least one requirement for a successful attack. Providing the report may further include obtaining protection data associated with protection measures that affect the requirements for a successful attack, performing each simulation in a plurality of Monte Carlo simulations for the attack type a number N of times based on the undesired event, the attack type, and the protection data, and in response to determining that the N performances of a simulation indicate at least one wildcard, performing it an additional N times. Providing the report may also include identifying a vulnerability of the protection measures to the attack type based on the performances of the plurality of Monte Carlo simulations and generating the risk analysis report for the undesired event based on the attack type and the vulnerability.

Abstract: An explosive cartridge actuated cable cutter device is presented which has a housing with a longitudinal axis and an axially extending bore therein where the bore has a circumferential step extending radially into the bore defining a reaction shoulder and a frame carried by the housing which extends axially at the cutting end of the device. A reaction blade is carried by the frame and extends laterally across the longitudinal axis and acts in conjunction with a cutting blade to shear power transmission line or underground cable. The shearing action is achieved through the use of a piston member which has a piston head and piston rod and is slideably mounted within the bore.

Abstract: A cutting type rescue tool having a body with an axis of actuation. A spacer on the body spaces a reaction arm, which reaction arm extends across the axis. An actuator barrel contains a piston from which a piston rod extends to a cutting blade that faces the reaction arm. The actuator barrel is slidably mounted in the body and is retained thereto. Braking shoulders on the actuator barrel and on the body oppose a decelerator device which reduces impact forces between the actuator barrel and the body, after the piston bottoms on the actuator barrel.

Abstract: An arming-firing device that provides handling safety in a rocket motor. arming-firing device provides pyrotechnic (out-of-line) and electrical (open circuit) safety features wherein the arming-firing device is armed by rotating a mechanical rotor by a solenoid that aligns multiple prongs of the barrier with multiple cavities of the rotor and this action simultaneously electrically arms (closes circuits) and mechanically enables the igniter whereupon receiving a firing signal starts the rocket motor. The mating of the barrier prongs with the rotor cavities obviates rebounding, thus affording proper ignition. The mechanical barrier and a solenoid return spring prevents inadvertent firing from any cause.
