  • Publication number: 20140253145
    Abstract: System and method for testing the reliability of a fuse blow condition. The fuse blow detection circuit includes a fuse circuit comprising a fuse having a first end coupled to ground. A common node is coupled to the second end of the fuse. A pre-charge circuit is coupled to the common node for pre-charging the common node to a pre-charged HIGH level. An inverter includes an inverter output and an inverter input, wherein the inverter input is coupled to the common node. A feedback latch is coupled between a voltage source and ground, and includes a latch input that is coupled to the inverter output and a latch output coupled to the common node. A test circuit is included that is coupled to the common node, wherein in a normal mode the test circuit adds strength to the feedback latch for purposes of maintaining the common node at the pre-charged HIGH level, such that in a test mode the feedback latch is weaker than in the normal mode for purposes of maintaining the common node at the pre-charged HIGH level.

  • Publication number: 20140214266
    Abstract: Systems, media, and methods are provided for oscillation monitoring. An aircraft system includes a first oscillation monitoring module and a second oscillation monitoring module. The first oscillation monitoring module is configured to select first oscillating portions of an input signal, generate a frequency signal that indicates a frequency of the first oscillating portions, and generate a first failure signal in response to the frequency of the first oscillating portions exceeding first oscillatory fault detection requirements for the input signal. The second oscillation monitoring module is configured to select second oscillating portions of the input signal based on the frequency signal generated by the first oscillation monitoring module and to generate a second failure signal in response to a frequency of the second oscillating portions exceeding second oscillatory fault detection requirements for the input signal.

  • Publication number: 20140200366
    Abstract: The present invention provides a method for reducing accumulation of solid materials when manufacturing a (meth)acrylic acid ester having low biacetyl content (less than 2 ppm) by adding an aromatic diamine under conditions which provide sufficient residence time and thorough mixing to react up to 100% by weight of the biacetyl in the crude (meth)acrylic acid ester stream, prior to separation and purification. A feedback method is also provided for reducing solids accumulation in the separation and purification equipment of such processes by measuring the biacetyl content and adjusting the aromatic diamine addition rate so that excess aromatic diamine can be minimized. A third embodiment provides a method for reversing an accumulation of solid materials during such processes, while still producing a (meth)acrylic acid ester having low biacetyl content (less than 2 ppm), by reducing or ceasing the addition rate of aromatic diamine for a period of time.

  • Patent number: 8690075
    Abstract: A common rail fuel injector includes a needle valve member that moves to open and close nozzle outlets for a fuel injection event responsive to pressure in a needle control chamber. Between injection events, the needle control chamber is fluidly connected to the fuel inlet by a first pathway that includes a Z orifice, and fluidly connected to the fuel inlet by a second pathway that includes an F orifice, an intermediate chamber and an A orifice. During an injection event, the needle control chamber is fluidly connected to a drain outlet by a third pathway that includes the A orifice, the intermediate chamber an E orifice and a buffer chamber, which may assist in avoiding cavitation erosion in a sensitive area associated with a flat control valve seat. Different performance characteristics are achieved by adjusting the sizes of the respective of F, A, Z and E orifices.
