Abstract: A temperature drift compensation method includes pre-aging a thermocouple, during which the thermocouple is subjected to temperatures and/or pressures that cause or facilitate an oxidation growth on the conductor elements of the thermocouple. During the pre-aging, temperature readings of the thermocouple are recorded, and a model including a time-based exponential expression is derived from the temperature readings. In addition, a temperature sensor system includes a pre-aged thermocouple, and a temperature compensation circuit that modifies initial temperature readings from the pre-aged thermocouple according to a model including a time-based exponential expression.

Abstract: A gas turbine engine fuel additive control system includes a sensor positioned to sense an operational parameter of a gas turbine engine that includes a compressor section, a combustion section, and a turbine section. The system also includes a control valve positioned to supply a fuel additive to a fuel line. The fuel line contains fuel for supply to the combustion section of the gas turbine engine to which the fuel additive is selectively added by injection into the fuel line. The system also includes a controller configured to monitor the operational parameter in real time during operation of the gas turbine engine and adjust the control valve to dynamically modulate an amount of the fuel additive being supplied in the fuel in accordance with operation of the gas turbine engine.

Abstract: An example engine control system may include an oxygen intake sensor; a fuel delivery device to control a rate of fuel delivery to the engine combustor; a combustor pressure sensor; a combustor temperature sensor; and a controller to receive at least one of an oxygen intake signal, a combustor pressure signal, and a combustor temperature signal; determine at least one of a reference specific fuel consumption (SFC) of the engine or a reference amount of a respective exhaust gas of a plurality of exhaust gases based on the oxygen signal, the pressure signal, and the temperature signal; compare at least one of the reference SFC or the reference amount of a respective exhaust gas to a respective threshold value; and control the fuel delivery device to control the rate of fuel delivery based on the comparison.

Abstract: A stockbutt system for rifles to abate shock during the firing of a rifle is disclosed, having a butt at the near end. The system includes a rifle and an insert with the butt having a near most first end in a generally planar configuration perpendicular to the axis of the barrel. The first end of the butt has a concave configuration when viewed from the side and a teardrop configuration when viewed from the end. The teardrop shape includes an upper semicircular curve at the top with a diameter essentially equal to the diameter of the widest portion of the butt. The teardrop shape further includes downwardly tapering side edges terminating in a U-shaped configuration at the bottom. The lower semicircular curve has a diameter less than the upper semicircular curve. The insert has an essentially flat far most face in its size and shape to correspond to the rearmost face of the butt. The insert is provided being fabricated of an elastomeric material to abate vibrations during the firing of a rifle.

Abstract: An air bag and steering lock device including a housing. The housing has a top half and a bottom half that allows the housing to be positioned around a column of a steering wheel for replacing the covering of the column. A J-bar member is provided. The J-bar has a back bar with a pair of lateral extents projecting in a forward direction. One of the lateral extents has an interior side with a plurality of catch slots adjacent an end. Lastly, a locking means is fixedly attached to the top surface of the top half of the housing. The locking means is capable of receiving the one lateral extent of the J-bar for locking the J-bar over the steering wheel to limit the steering wheel's movement and disassembly.
