Title: Neutron warhead with very high speed fragmentation
Inventor: JOHN ERNEST ANDERSON
IPC: G21B1/03
Filed: 2018-04-14
Abstract: A pure fusion neutron warhead with high speed fragmentation is disclosed for use in the field of defence to, for example, intercept ballistic, aeroballistic and hypersonic missiles. Electromagnetic energy from its explosion accelerates lightweight fragments to sufficient velocity to intercept a target despite not being launched before that point. Apparatus for providing the electromagnetic energy comprises a shock cavity filled with high-pressure gas. Detonation of an array of explosive lenses causes the dissociation of said gas, thereby generating electromagnetic radiation which is focussed and directed by at least one ‘eye-mirror’ 8 towards a cryogenic spherical target 121 for inertial confinement fusion 121, said target being provided in a hohlraum 120. An ablator 68 and at least one fragment 69 to be accelerated are also provided.

Title: Methods and devices for double-spend relay in a blockchain network
Inventor: STEVEN PATRICK COUGHLAN
IPC: G06Q20/38
Filed: 2020-04-03
Abstract: Relaying double-spend attempt notifications in a blockchain network. A double-spend notification is received from a node in the blockchain network, such as a mining node that has detected a double-spending attempt. The notification contains two transaction identifiers and is signed by a miner identifier. Transaction data is obtained for the two transactions associated with the identifiers. A determination is made as to whether the two transactions have at least one matching input. If they do have a matching input, the double-spend notification is confirmed as valid and it is transmitted/relayed to at least one other node in the network. Otherwise, the notification is invalid and is not propagated. Invalid notifications may have a negative impact on a reputation score of the associated miner. A repudiation notice may be generated by a node that determines a double-spend notification is invalid.
