Abstract: An event marking device marks the real time at which notable events occur. When a notable event occurs, a user causes the event marking device to generate a trigger signal. The event marking device includes a real-time clock. When the user causes a trigger signal to be generated, a microcontroller of the event marking device reads the real-time clock and writes trigger event data to a memory indicating a real time at which the trigger signal was generated. The event marking device outputs the trigger event data to an external device.

Abstract: A system presents a media playback. The system receives a plurality of time stamped trigger data. The system reads a plurality of media segments from a media capture device. Each media segment corresponds to a respective time stamped trigger datum. The system outputs the plurality of media segments as a playback including the plurality of media segments.

Abstract: A perforated flame holder and burner including a perforated flame holder provides reduced oxides of nitrogen (NOx) during operation. The perforated flame holder includes a pattern of elongated apertures extending between a proximal and a distal surface of the flame holder relative to a fuel nozzle. The perforated flame holder can provide a significantly reduced flame height while maintaining heat output from the burner.

Abstract: A system and method allows a user to enter a command capture audio, video, and/or still pictures that commence at a moment in time earlier than entering the command.

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: A computer method for establishing a commodity price index includes receiving, via a web server, transactions for a plurality of first electronic currency denominated commodity or commodity future contracts, and recording, with a server computer operatively coupled to the web server, settlement prices for the plurality of the first electronic currency denominated commodity or commodity future contracts on a distributed ledger. The computer method includes reading, with the server computer, from the distributed ledger, at least a portion of the first electronic currency denominated commodity or commodity future contracts settlement prices, and determining a current electronic currency index price from the at least a portion of the first electronic currency denominated commodity or commodity future contracts settlement prices. The computer method includes displaying the current electronic currency index price on an electronic display.

Abstract: A computer method and graphical user interface (GUI) for transferring a commodity includes establishing a smart commodity contract carried on a distributed ledger for transfer of a commodity requiring plural steps before delivery, issuing a plurality of electronic tokens representing a completed delivery of the commodity, and displaying, on an electronic display of a user device, a GUI including an identity of the commodity contract with a future delivery date. A payment to a first party is transacted for at least a portion of costs corresponding to completion of a first step by executing a transaction on the distributed ledger. The payment to the first party may be made by transferring a portion of the issued tokens to an electronic wallet of the first party.
