Abstract: A combustion system includes a fuel and oxidant source that outputs fuel and oxidant, a first perforated flame holder, and a second perforated flame holder separated from the first perforated flame holder by a gap. The first and second perforated flame holders sustain a combustion reaction of the fuel and oxidant within the first and second perforated flame holders.

Abstract: A combustion system includes a distal flame holder, a pilot fuel distributor, a main fuel distributor, an oxidant source, an array of sensors, and a controller. The oxidant source outputs an oxidant. The pilot fuel distributor supports a pilot flame configured to preheat the distal flame holder by outputting a pilot fuel at least when the combustion system is in a preheating state. The main fuel source outputs a main fuel in the standard operating state. The distal flame holder is configured to support a combustion reaction of the main fuel and the oxidant in the standard operating state. The sensors are configured to sense parameters of the pilot flame and the distal flame holder and to output sensor signals to the controller. The controller executes software instructions that include adjusting the flow of the main fuel, the pilot fuel, and the oxidant responsive to the sensor signals.

Abstract: Computer methods and systems provide management of payload data represented by electronic tokens. Applications may relate to asset-backed fungible tokens as well as non-fungible tokens. A payload data file may be added or kept current after initial token genesis by specifying, in token data, a pointer (e.g., as either a TXID specifying a wallet address as an endpoint, or as the wallet address) to one or more transactions that carry, such as in an OP_Return field, a link to a linking payload or to the added or current payload data file. A single transaction specifying the wallet address may thus update or enhance any number of electronic tokens linked to the payload data file.

A combustion system includes a UWB combustion sensor. A method for operating a combustion system includes operation of a UWB combustion sensor.

Abstract: A system provides an immutable record of human creative output as one or more secure disclosure threads. The immutable record may be stored on a blockchain. Addresses to the data corresponding to the one or more secure disclosure threads may be encrypted and stored on a blockchain. The immutable record and the addresses to the data may be stored on the same blockchain. The immutable record and the addresses to the data may be stored on different blockchains.
