Abstract: An example ram air turbine stow abort assembly includes a release pin movable between an engaged position that prevents rotation of a drive shaft and a released position that allows rotation of the drive shaft. A release lever is rotatable about an axis in response to the release pin being in the engaged position or the released position. A pawl has a link to the release lever. The link causes the pawl to move toward the axis from a locking position to a clearance position. The pawl is positioned to engage a lock when in the locking position to prevent movement of the ram air turbine assembly to a stowed position when the turbine blades are misaligned.

The database includes a plurality of records, each record representing a respective virtual storage media and including at least: a respective unique identifier assigned to the virtual storage media; a respective Private key and certificate assigned to the virtual storage media; a current content value, and a log of content transfers. The controller executes transfer-in and transfer-out processes in respect of each of the virtual storage media. The transfer-in process includes steps of: receiving a content transfer message including at least a message content to be transferred and the respective identifier assigned to a recipient virtual storage media; accessing the record representing the recipient virtual storage media; and storing the message content in the current content of the recipient virtual storage media.

Abstract: A turbine having a cam follower operable to control turbine blade pitch in association with a position thereof is provided and includes an axially movable plate, a rotational and axially movable flyweight and a system operably coupled to the plate and the flyweight whereby, at low RPMs, the system prevents flyweight rotation such that the plate and the flyweight position the cam follower at a first position, at medium RPMs, the system permits flyweight rotation such that the plate and the flyweight position the cam follower at a second position, and, at high RPMs, the system prevents further flyweight rotation and permits initial axial movement of the plate and the flyweight such that the plate and the flyweight position the cam follower at a third position.

Abstract: An assembly includes an actuator assembly having a housing, a piston positioned at least partially within the housing and movable relative to the housing for an overall actuation stroke, a first spring operatively engaged between the piston and the housing to provide actuation biasing force therebetween, a second spring operatively engaged with the piston, and a spring guide. The spring guide is operatively engaged with the first spring and operatively engaged with the piston via a sliding connection. The spring guide is further configured to limit a stroke of the first spring such that the first spring contributes actuation biasing force between the piston and the housing for only a fractional portion of the overall actuation stroke of the piston.

Abstract: A ram air turbine (RAT) in which a cam follower is operably coupled to turbine blades such that a cam follower position determines turbine blade pitch.

Abstract: An example ram air turbine generator assembly includes a generator housing that holds a generator in axial alignment with a hydraulic pump. The generator housing includes a wall having contacting portions that contact a stator of the generator and spaced portions that are radially spaced from the stator. The generator wall is designed to be strong enough to withstand HLSD and windmilling vibrations, while flexible enough to accommodate thermal expansion.

Abstract: A secure asset storage and transfer system. A first display displays a first bar code encoding a request message including an asset value amount to be transferred. A first camera-equipped device is configured for: reading the first bar code, decoding the first bar code to recover the request message; generating a value transfer message for transferring asset value amount to be transferred from a storage medium associated with the camera-equipped device; encoding the value transfer message to generate a corresponding second bar code; and displaying the second bar code on a second display. A second camera-equipped device is configured for reading the second bar code, and decoding the second bar code to recover the value transfer message.

Abstract: A ram air turbine assembly is provided including a release cable coupled at a first end to a turbine release pin and coupled at a second end to a release lever. Aluminum tubing surrounds a portion of the release cable. An upper cable bracket supports the aluminum tubing adjacent the first end of the release cable. A lower cable bracket supports the aluminum tubing adjacent the second end of the release cable. The lower cable bracket includes a threaded bushing having an axial bore for receiving the release cable. The threaded bushing is in direct contact with an end fitting coupled to the aluminum tubing.

Abstract: An electronic content exchange system includes a communications medium and at least two storage media. Each storage media includes an interface configured to send and receive messages, a memory storing a current content, a respective unique identifier, and a log of content transfers; and a controller. The controller receives a content transfer message including at least a message content to be transferred, and executes a Transfer-in process to increase the current content by the message content to be transferred and record information of the transfer in the log. The controller receives, via the interface, a content transfer request message including at least a message content to be transferred, and executes a Transfer-out process to generate and send a content transfer message including the message content to be transferred, decreasing the current content by the message content to be transferred; and recording information of the transfer in the log.

Abstract: A ram air turbine assembly includes a preferentially located mass that modifies the resonance frequency of the assembly so that vibration is reduced to desired levels. The example mass can be fixed in a specific location on the ram air turbine or can be deployable once the ram air turbine is moved to an operating position.

Abstract: A data mashup system having information extraction capabilities for receiving multiple streams of textual data, at least one of which contains unstructured textual data. A repository stores annotators that describe how to analyze the streams of textual data for specified unstructured data components. The annotators are applied to the data streams to identify and extract the specified data components according to the annotators. The extracted data components are tagged to generate structured data components and the specified unstructured data components in the input data streams are replaced with the tagged data components. The system then combines the tagged data from the multiple streams to form a mashup output data stream.

Abstract: A hydraulic system for a ram air turbine includes a hydraulic pump having a high pressure fluid outlet port, a housing, a pivot post arranged to pass through the housing and defining a mechanical pivot relative to the housing about an axis, a transfer tube positioned between the high pressure fluid outlet port of the hydraulic pump and a port in the housing for the high pressure fluid outlet path, and seal elements positioned at or near opposite ends of the transfer tube. A fluid inlet path and a high pressure fluid outlet path pass through the housing and the pivot post. The transfer tube has a crowned end.

Abstract: An Internet marketing venue focused around a Web-based casual game. The game is an entertainment site designed for simplicity of play with low commitment. Sponsors provide prizes and rewards, which are made available to the highest-scoring players. These winners select the prizes they most prefer, while non-winners earn points to be “spent” on rewards they choose. In this way, sponsors are connected to customers with both a proven interest and emotional investment in their products.
