  • Publication number: 20060255303
    Abstract: A regulator valve includes dual actuators that operate according to different principles to position a valve element to either an open or a closed position. One actuator, which is an electromechanical actuator, operates in response to electrical command signals. The other actuator, which is a pneumatic actuator, operates in response to a fluid pressure.

  • Publication number: 20060255307
    Abstract: The present invention provides a collapsible shaft and control assembly that is useful for transferring rotational control valve movements to a control surface. The invention includes a housing, shaft, and actuator arm. The housing defines a hollow cylinder. The shaft has a resilient end with a plurality of flexible strips capable of radial bending so as to transition between an expanded position and a compressed position. The shaft is positioned in the hollow cylinder, in the expanded position, so that the shaft can rotate. The actuator arm is positioned within the resilient end of the shaft so as to maintain the resilient end of the shaft in the expanded position. Both the actuator arm and shaft include reciprocal engagement means, and the actuator arm and shaft are positioned so as to engage the reciprocal engagement means. A rotational movement of the actuator arm thus causes a rotational movement of the shaft. A flapper affixed to the shaft can direct air depending on the radial position of the shaft.

  • Publication number: 20060179800
    Abstract: A filter bypass valve is disposed in parallel with an aircraft cabin air filtration system air filter. During normal operation, air is filtered through the air filter at an air flow that meets air flow requirements of the system. The bypass valve is designed to remain closed during normal use, and to open if the differential pressure across the air filter reaches a predetermined opening differential pressure to allow airflow to be partially or fully diverted around the air filter.

  • Publication number: 20060142913
    Abstract: A vehicle fleet management information system identifies location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager. Each fleet vehicle has an assigned time slot to transmit its reporting information over a communications network without interfering with transmissions from other vehicles in their own respective time slots. A timing control phase lock loop (PLL) provides precise time synchronization for timing corrections from a global positioning system (GPS) based time reference. A dual band full-duplex interface of the network has TDMA on one-half and broadcast on the other half. Microprocessor time processing units in components of the network perform precise clock synchronization. Space diversity performed on received vehicle transmitted messages avoids data corruption.

  • Publication number: 20050241705
    Abstract: The present invention provides a lounge valve mounting housing and assembly. The housing and assembly are useful for directing air through ducts, and particularly the assembly is useful for directing air, or other fluid, through Y-shaped junctions. The housing comprises in part a plate and a supported platform. The plate mounts to a duct. An actuator assembly can be affixed to the platform. The housing further includes a cylinder; a shaft is disposed within the cylinder and extends into the duct. A flapper affixed to the shaft can direct air depending on the radial position of the shaft. The housing and assembly offers weight and capital advantages over dual valve assemblies.
