Abstract: Video containers are expanded to encapsulate auxiliary data and metadata linking video content with relevant portions of auxiliary data for download during playback of particular video content. Auxiliary data is parsed into areas of interest and associated with the video content including the same areas of interest. During playback a viewer is provided access to relevant portions of the auxiliary data according to the encapsulated metadata describing the relevant portions.

Abstract: A processor may receive, from two or more nodes in the blockchain, respective consideration from each of the two or more nodes at a first time. The processor may receive respective updates from each of the two or more nodes at a second time. The processor may determine whether a single node of the two or more nodes is available after the respective updates. The processor may designate the single node as the block generator node.

Abstract: A distributed transaction processing system, comprising a peer node associated with a blockchain network. The peer node may be adapted to record join-time parameters for a plurality of blockchain nodes, compare a first join-time parameter for a first node of the plurality of blockchain nodes to a remainder of the join-time parameters for a remainder of the plurality of blockchain nodes, calculate, based on the comparison, a transaction signature probability (TSP) for one or more nodes within the plurality of blockchain nodes, select according to the calculated TSPs, a signature node from among the one or more nodes having calculated TSPs to sign a transaction block, and calculate, by the selected signature node, a digital signature for the transaction block.

Abstract: A hydrogen closed-cycle hardening unit is disclosed that consisting of a vacuum oven with an internal quenching and circulation system, adjusted to operate under a pressure of 2 MPa, fitted with conduits and valves for feeding and discharging of quenching atmosphere. The oven, fitted with a hydrogen and/or nitrogen inlet line and an operating gas outlet line, is connected to two conduits, between the conduits' valves, and, through these conduits, to a unit of two containers. The first container, which is connected to an external hydrogen source, contains a metal alloy absorbing hydrogen as a high-pressure hydride, while second container contains a metal alloy absorbing hydrogen as a low-pressure hydride. Both containers are connected by another conduit.
