Abstract: A system and method for operation of an autonomous vehicle (AV) yard truck is provided. A processor facilitates autonomous movement of the AV yard truck, and connection to and disconnection from trailers. A plurality of sensors are interconnected with the processor that sense terrain/objects and assist in automatically connecting/disconnecting trailers. A server, interconnected, wirelessly with the processor, that tracks movement of the truck around and determines locations for trailer connection and disconnection. A door station unlatches/opens rear doors of the trailer when adjacent thereto, securing them in an opened position via clamps, etc. The system computes a height of the trailer, and/or if landing gear of the trailer is on the ground and interoperates with the fifth wheel to change height, and whether docking is safe, allowing a user to take manual control, and optimum charge time(s). Reversing sensors/safety, automated chocking, and intermodal container organization are also provided.

Abstract: Fuses can store different delay states to cause execution of a command to be staggered for different memory dies of a memory package. Fuse arrays can be included in the memory package and programmed to cause execution of a command to be delayed by different amounts for different dies. The fuse arrays can be fabricated and then programmed to cause different delays for different dies.

Abstract: An electrohydraulic servo system to actuate the power shaft of a fuel control system from the cockpit throttle including electrical devices responsive to the position of the throttle that actuates a hydraulic piston for moving the power shaft together with a backup system that assures a shaft position proportional to the throttle position. This permits the use of electrical lines from the cockpit to the engine rather than mechanical cables and linkages.

Abstract: The 3-D cam utilized for acceleration scheduling of a fuel control for a turbine type of power plant is also utilized to schedule the position of the stator vanes of the power plant and to provide speed and temperature schedules for idle and maximum speed. A single follower responding to the same profile on the cam controls both stator vane position and idle speed. The stator vane and idle speed contour on the 3-D cam controls idle speed through a single linkage and readjusts the W.sub.f /P.sub.3 ratio lever to adjust fuel flow.

Abstract: For a fuel control for a turbine type of power plant a throttle valve servo piston combination including a servo control valve operated off of a multiplication lever system wherein said throttle valve servo piston combination is rotated resulting in a smaller unit and achieving a reduction in its size and that of the control valve and lever system. A gear secured to the rotatably supported mechanism is located in a judiciously selected position within the drain portion of the control and the maximum fuel flow limit changes the feedback system from a force balance one to a position one during maximum limiting.

Abstract: This invention relates to an electromechanical pumping and fuel metering means interfacing an electronic fuel control adapted for small engines. A centrifugal engine driven pump and electrically driven pump are combined such that the electrically driven pump pressurizes the fuel at low crank up speeds and continuously meters fuel to the burner section and the centrifugal pump pressurizes the fuel at all other times, so as to utilize the centrifugal pump during its high efficiency regime and the electrically driven pump when the centrifugal pump is not at its high efficiency regime.

Abstract: A load on the flyweight transmitted through the pilot valve to preload the thrust bearings of a speed sensor serves to prevent the fuel control for a turbine type of power plant from shifting to its emergency schedule from the starting or normal schedule or vice versa at an indeterminant speed. Thus, the preload assures that the transition from one schedule to the other always occurs at a predetermined compressor rotational speed.
