    Abstract: A method of operating a pressure compensated fuel injector includes: filling a fuel chamber with a charge of fuel by closing an injector valve and circulating a fuel from a fuel source through a plurality of recirculating valves and a cap valve; then isolating the fuel chamber and the charge of fuel from the fuel source; then equalizing a pressure within the fuel chamber to a rising pressure outside the fuel chamber by reducing a volume of the isolated fuel chamber; and then activating a solenoid that is coupled to the injector valve, opening the injector valve; and then further reducing the volume of the isolated fuel chamber to apply an over pressure within the chamber, pumping fuel from the fuel chamber through the injection orifice.

    Abstract: An automated test equipment interface system, e.g., for attaching a handler to a test head, includes a device interface board assembly. The device interface board assembly includes a stiffener frame having a frame body that is configured for attachment to a test head, alignment brackets connected to the frame body, and cam followers connected to the alignment brackets. The system also includes a docking device. The docking device includes a docking plate that is configured for attachment to a handler, pull-down ramps connected to the docking plate and movable between a retracted position and an extended position, an actuator operable to initiate movement of the pull-down ramps, and a coupling that translates movement of the actuator to corresponding movements of the pull-down ramps. The pull-down ramps can include cam surfaces that are configured to engage the cam followers of the device interface board assembly during movement between the retracted and extended positions to pull the device interface board assembly towards the docking plate.

    Abstract: Methods and apparatus are described for a reciprocating combustion engine. A method includes operating a dual-piston engine including introducing a gas into a pair of combustion chambers; introducing a fuel into the pair of combustion chambers; compressing the gas; combusting the gas and the fuel; and exhausting combusted gases. Each of the pistons drives a reciprocating crankshaft that protrudes through a cylinder wall and cooperatively rotate a pair of rotors by engaging substantially sinusoidal cam tracks on the rotors. An apparatus includes a cam driven, concentric drive rotary-valve dual-piston engine.

    Abstract: The invention constitutes a unique hardware zero overhead interrupt and task change system for the reduction or elimination of interrupt latency and task change processing overhead delays in computer architectures. Without loss of time, the system performs complete task state saving and restoration between one cycle and the next without software intervention. For each Central Processing Unit (1) register, the invention uses one or more auxiliary latches (3, 4) wherein one latch (3, 4) is used as the "running" latch and one of the auxiliary latches is attached to task storage memory. The invention swaps connections between alternate "running" registers and auxiliary registers while transferring other tasks to and from task storage memory (2). The invention provides a task linking system to allow the linking of tasks for the mandatory sequential execution of the linked tasks. Further, the invention includes a priority "impatience" counter system to increase the relative priorities of various tasks as they approach their task deadlines.
