Abstract: Apparatus and associated methods relate to an attritable torch ignition system for a gas turbine engine. The attritable torch ignition system includes a fuel pre-heating component, a solenoid valve and an ignition controller. The ignition controller is configured to cause the solenoid valve to direct fuel to the pre-heating component during an ignition phase and to direct stop fuel from being directed to the fuel pre-heating component after the fuel has ignited. Ignition is caused when preheated fuel is mixed with air with sufficient energy from the heating element and directed into a combustion chamber of the gas turbine engine.

Abstract: Implementations described and claimed herein provide systems and methods for detection, tracing, and prediction of frac hits (or other type of fracture driven interactions) via automated approaches using a variety of multi-disciplinary data. In some implementations, frac hits may be automatically detected in real-time using production data including pressure and production water, gas, and oil rates, as well as other in-well and well-head measurements via both deterministic and AI-based methods. The detected frac hit information may then be combined with completion data to identify likely subsurface location candidates for frac hit origins. Those location candidates can then be compared with subsurface fault distribution to identify the communication pathways for fluid and/or pressure. The above steps form a complete “Monitoring-Tracing-Prediction-Alerting” loop for frac hit diagnostics which can be used to support the completion and production of wells in real-time or in historical context.

Abstract: An assembly is provided for a gas turbine engine. This assembly includes a fuel injector. The fuel injector includes a nozzle and a plurality of discrete fuel circuits. The discrete fuel circuits include a first fuel circuit, a second fuel circuit and a third fuel circuit. The nozzle extends axially along an axis to a nozzle tip. The first fuel circuit includes a first fuel outlet disposed at the nozzle tip. The second fuel circuit includes a plurality of second fuel outlets arranged circumferentially about the axis at the nozzle tip in a second fuel outlet array. The third fuel circuit includes a plurality of third fuel outlets arranged circumferentially about the axis at the nozzle tip in a third fuel outlet array.

Abstract: A fuel pre-heating component in a gas turbine engine includes a component housing extending around a central axis from a first end to a second end, wherein the component housing includes walls that define an inner chamber, a heating element positioned inside the inner chamber, and a plurality of internal fuel channels disposed within the component housing and configured to be heated by the heating element.

Abstract: A downhole check valve may be used in a wellbore to allow a variety of pressure diagnostics to be easily captured and compared within a single monitor well. Pressure responses from below the check valve are open to the formation and provide detailed stress shadowing, poroelastic pressure response, and other sensitive pressure measurements from the open toe, allowing ingress from the wellbore while additional responses can be obtained above the check valve provided the pressure events below do not overcome the pressure above or the spring setting of the valve. This allows for an increase in available data points from the monitor well and a direct comparison of geomechanical and mechanical responses.

Abstract: A connecting table Tete-A-Tete system in one embodiment includes a connecting table with two arm receptacle portions each configured to removably receive an arm of a respective seat. The system includes a coupling bar movable between a first position whereat the arms can be inserted into or removed from the respective arm receptacle portions and a second position whereat the arms cannot be inserted into or removed from the respective arm receptacle portions.

Abstract: Applications that run on an overlay network-based managed service achieve high performance gains using a set of TCP optimizations. In a first optimization, a typical single TCP connection between a client and an origin server is broken into preferably three (3) separate TCP connections. These connections are: an edge-to-client connection, an edge-to-edge connection, and edge-to-origin connection. A second optimization replicates TCP state along the connection to increase fault tolerance. In this approach, preferably a given TCP connection is maintained on two servers. When a packet is received by one server, called the primary, its state is updated and then passed to a second server, called the backup. Only when the backup sends an acknowledgement back to the primary can it then send a TCP acknowledgement back to the host that originally sent the packet. Another optimization reduces connection establishment latency.

Abstract: A relay service enables two peers attempting to communicate with one another to each connect to a publicly-accessible relay server, which servers are associated with an overlay network and are selected by a directory service. After end-to-end connectivity is established, preferably the hosts communicate with each other by relaying data packets via the overlay network relay servers. Communications (both connection control messages and data being relayed) between a host and a relay server occurs at an application layer using a modified version of the TURN protocol.

Abstract: An electronic guitar pick, system, system and method may include an enclosure forming a cavity, the enclosure having a first end that is substantially pointed and a second end opposite the first end that is substantially flat, the enclosure having a thickness proximate the cavity greater than a thickness proximate the first end. The electronic guitar pick, system, and method may further include a sensor contained, at least in part, within the cavity and configured to generate a sensor output based on an interaction with the enclosure and a sensory output device, communicatively coupled to the sensor, configured to output a sensory output based, at least in part, on the sensor output.
