  • Publication number: 20190159716
    Abstract: An apparatus for generating a quantifier of cognitive skills in an individual includes a user interface, a memory to store processor-executable instructions, and a processing unit communicatively coupled to the user interface and the memory. Upon execution of the processor-executable instructions by the processing unit, the processing unit is configured to: render a first instance of a task with an interference at the user interface, requiring a first response from the individual to the first instance of the task in the presence of the interference and a response from the individual to at least one evocative element. One or more of the first instance of the task and the interference comprises the at least one evocative element. The user interface is configured to measure data indicative of the response of the individual to the at least one evocative element, the data comprising at least one measure of emotional processing capabilities of the individual under emotional load.

  • Patent number: 10274201
    Abstract: A fuel injector for a gas turbine engine is disclosed. The fuel injector includes two primary tubes, a secondary tube, a primary gas gallery, and a secondary gas gallery. The two primary tubes are connected in a parallel configuration to provide a main gas fuel to the primary gas gallery. The secondary tube provides the main gas fuel to the secondary gas gallery independent from the two primary tubes and the primary gas gallery. The primary gas gallery and the secondary gas gallery provide the main gas fuel to a premix passage independently allowing for robust control of the gas turbine engine.

  • Patent number: 10234142
    Abstract: A fuel injector for a combustion engine includes an injector head including a nozzle, a premixer, and a distributor structured to distribute a plurality of different fuels to different sets of fueling orifices in the premixer. A pilot assembly of the fuel injector is coupled to the premixer and includes a first fueling passage for a first fuel and a second fueling passage for a second fuel. Multiple sets of fueling orifices are positioned within the fuel injector, the fueling orifice sets being selectively connectable to a plurality of different fuel supplies, and both located and sized so as to accommodate a wide range of flow rates to enable a combustion engine coupled with the fuel injector to operate on fuels having a range of Wobbe numbers and compositions.

According to an aspect, a method includes using at least one processor and memory for transmitting a request and a baseline timestamp for an updated resource state based on a current resource state, wherein the baseline timestamp defines a time period for the updated resource state. The method also includes determining the updated resource state based on the baseline timestamp and the current resource state. The method also includes providing the determined updated resource state and current timestamp of the determined updated resource state. Additionally, the method includes setting a current baseline resource state based on a current timestamp of the determined updated resource state.
