Abstract: A transaction block in a blockchain is generated. The transaction block in the blockchain comprises a token that points to blockchain data in a tokenization table. An event is detected (e.g., an administrative event). The event is to forget the blockchain data in the tokenization table. In response to detecting the event, the blockchain data in the tokenization table is forgotten. For example, forgetting the blockchain data may comprise permanently deleting the blockchain data in the tokenization table and/or permanently deleting an encryption key for the blockchain data in the tokenization table.

Abstract: A heat dissipation structure for a belt starter generator (BSG) which reduces the temperature of one or more ground screws used to connect a printed circuit board (PCB) to a cooling device of the BSG. The PCB is part of an inverter, and the inverter of the BSG is grounded using two ground screws that fix the PCB to the cooling device. A heat dissipation bridge is connected to the two ground screws, the PCB, and the cooling device. The heat dissipation bridge is connected to the grounds screws such that the heat dissipation bridge is located and in contact with an area of the cooling device where the coolant is flowing through a flow cavity. The heat dissipation bridge absorbs the colder temperature from the cooling device therefore lowers the temperatures of the ground screws to a safe level for the components of the PCB.

Abstract: In a distributed replicated storage system, an active server may, during normal operation, service requests from clients, and back up its persistent storage to a backup server. The backup server may be configured to become an active server autonomously if the active server fails. If a network connection between the active server and the backup server fails, severing the connection between the active server and the backup server, the backup server may become a second active server and begin to service requests from clients, and the original active server may continue to service requests from clients. This may result in inconsistencies in the persistent storage of the original active server and of the second active server. As such, a system and method for intelligent merging of primary and backup data in a distributed replicated storage system are provided.

Abstract: Hypochlorite salts and substantially dehydrated acid-form cation exchange resin beads are combined at specified ratios within a porous enclosure such as a pouch or sachet. Hypochlorous acid solutions are produced on demand by introducing the mixture-containing pouch into a chemical excess of water. Spontaneous exchange reactions occur at room temperature within a few minutes to produce aqueous hypochlorous acid, while the cations from the hypochlorite salt are simultaneously sequestered by the resin beads. The resin beads remain contained within the original porous enclosure to allow mechanical isolation or separation from the resulting solution.
