    摘要： A delivery system includes a reservoir for storing pressurized fluid and a piston rod passing through the reservoir and having an end portion with a dimension larger than the piston rod. A sleeve is configured to engage the end portion of the piston rod such that when the piston rod is advanced, the end portion seals an opening in the sleeve. The sleeve and the end portion function as a piston for extracting fluid from a delivery chamber. When the piston rod is retracted, the sleeve engages a portion of the end portion to permit the reservoir to communicate with the delivery chamber through the opening. Methods of use are disclosed.

    摘要： The invention constitutes a unique hardware zero overhead interrupt and task change mechanism 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.

    摘要： Pulse communications using precision timing includes detecting a pulse stream from a pulse code modulated carrier signal; transforming the pulse stream into a reshaped pulse stream; transforming the reshaped pulse stream into a counter gate stream; and recovering a data stream from the counter gate stream. The reshaped pulse stream is transformed into the counter gate stream with a digital circuit.

    摘要： 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.
