  • Patent number: 10876472
    Abstract: A spark-ignited (SI) internal combustion (IC) engine designed to operate on high octane fuels, such as gasoline, is reconfigured to operate on low octane fuels including logistically preferred distillate fuels, such as diesel or JP-8. Design modifications involve coupling a fuel reformer module to the internal combustion engine. Auxiliary components include a system control module, a heat exchange module, a bypass valve to facilitate start-up, and/or a throttle body to control a reformate-oxidizer mixture fed to the engine. Small portable generators having 0.3-3.0 kWe power output are disclosed based upon the modified SI-IC engine design.

  • Patent number: 10738996
    Abstract: A gas-fired burner adapted for use on a liquid fuel. A method for essentially smokeless start-up and steady state operation of a gas-fired burner on a liquid fuel. The apparatus integrates a catalytic liquid fuel reformer with a flame burner designed for operation on a gaseous fuel of high Wobbe Index, e.g., natural gas. The method involves reacting a mixture of a liquid fuel and oxidant in a catalytic reformer to obtain a gaseous reformate having a low Wobbe Index; and thereafter combusting the gaseous reformate, optionally augmented with liquid co-fuel and oxidant, in the gas-fired burner under diffusion flame conditions. The invention allows commercial gas-fired appliances to be operated on a liquid fuel, thereby offering advantages in logistics and camp operations.

  • Patent number: 10147524
    Abstract: A resistor includes a substantially cylindrical resistive element having a resistance of less than about 1 m?, a substantially cylindrical first termination electrically connected to the resistive element and a second termination electrically connected to the resistive element. The substantially cylindrical first termination is hollow to allow for accepting a connection such as from a battery cable. In addition there may be sense leads present on the resistor. A method of forming a substantially cylindrical resistor includes forming a hollow cylindrical resistor body by rolling a flat sheet comprising a resistive element and a first termination and a second termination joined on opposite ends of the resistive element.

  • Patent number: 9760375
    Abstract: A processor core includes even and odd execution slices each having a register file. The slices are each configured to perform operations specified in a first set of instructions on data from its respective register file, and together configured to perform operations specified in a second set of instructions on data stored across both register files. During utilization, the processor receives a first instruction of the first set specifying an operation, a target register, and a source register. Next, a second instruction upon which content of the source register depends is identified as being of the second set. In response, the first instruction is dispatched to the even slice. In accordance with the operation specified in the first instruction, the even slice uses content of the source register in its register file to produce a result. Copies of the result are written to the target register in both register files.

  • Patent number: 9684749
    Abstract: A list of input registers and output registers for a circuit design are provided. The circuit design is modified by traversing output connections paths for each input register and replacing any register in the output connection paths with a wire unless the register is a listed output register. An initial total cycle time value for the modified circuit design is determined. A gate level description for the modified circuit design is obtained by a macro synthesis with the initial total cycle time value. The total cycle time value for the modified circuit design is then varied in order to determine the theoretical limit of the modified circuit design. This theoretical limit is realized when negative slacks are present in a macro synthesis of the modified circuit design for a given total cycle time value. Based on this theoretical limit, the minimum pipeline depth of the circuit design is determined.

  • Patent number: 9523982
    Abstract: A flight control system for at least one tethered gyroglider along a flight path consistent with at least one flight mission is configured to fly the gyroglider within a portfolio of winds, managing an interaction between portfolios of at least four envelopes including wind, gyroglider performance, flight and base station. Every flight mission corresponds to at least one flight path associated with a set containing at least one first value and at least one second value. The control system is provided with a learning and library manager comprising a repository having stored sets of first values and associated second values for each flight path. The current first values associated with a current mission are corrected based on predicted or experienced flight paths and measurable outputs to attain the desired flight path. The corrected, experienced values, flight path and measurable output are further stored in the repository for further learning.

  • Patent number: 9502171
    Abstract: An inductor includes an inductor body having a top surface and a first and second opposite end surfaces. There is a void through the inductor body between the first and second opposite end surfaces. A thermally stable resistive element positioned through the void and turned toward the top surface to forms surface mount terminals which can be used for Kelvin type sensing. Where the inductor body is formed of a ferrite, the inductor body includes a slot. The resistive element may be formed of a punched resistive strip and provide for a partial turn or multiple turns. The inductor may be formed of a distributed gap magnetic material formed around the resistive element. A method for manufacturing the inductor includes positioning an inductor body around a thermally stable resistive element such that terminals of the thermally stable resistive element extend from the inductor body.
