Abstract: One or more devices providing improved security for any database including a smart contract or distributed application executing on a virtual machine. Embodiments provide monitoring and incident response for execution of the smart contract or distributed application running on a blockchain, or any other distributed ledger technology. An aspect of some embodiments is detection of anomalies when executing the smart contract or distributed application in real-time. Embodiments may immediately respond to the detected anomalies, e.g., by switching control to a human operator, a reactive machine, or a machine learning operator. In an embodiment, operator response may include i) freezing execution, ii) resuming execution, or iii) reverting execution.

Abstract: The invention includes a method of joining two components. The method includes providing at least two components to be joined, a reactive multilayer foil, and a compliant element, placing the reactive multilayer foil between the at least two components, applying pressure on the two components in contact with the reactive multilayer foil via a compliant element, and initiating a chemical transformation of the reactive multilayer foil so as to physically join the at least two components. The invention also includes two components joined using the aforementioned method.

Abstract: The present inventors have observed that in some applications of reactive composite joining there is escape of a portion of the molten joining material through the edges of the joining regions. Such escape is not only a waste of expensive material (e.g. gold or indium) but also a reduction from the optimal thickness of the joining regions. In some applications, such escape also presents risk of short circuits or even fire. In this invention, two approaches are taken toward preventing damage to surroundings by the escape of molten joining material. First, escape may be prevented by trapping or containing the molten material near the joint, using barriers, dams, or similar means. Second, escape may be reduced by adjusting parameters within the joint, such as solder composition, joining pressure, or RCM thickness.

Abstract: A method for joining component bodies of material over bonding regions of large dimensions by disposing a plurality of substantially contiguous sheets of reactive composite materials between the bodies and adjacent sheets of fusible material. The contiguous sheets of the reactive composite material are operatively connected by an ignitable bridging material so that an igniting reaction in one sheet will cause an igniting reaction in the other. An application of uniform pressure and an ignition of one or more of the contiguous sheets of reactive composite material causes an exothermic thermal reaction to propagate through the bonding region, fusing any adjacent sheets of fusible material and forming a bond between the component bodies.
