Abstract:
A phased array antenna system on an aircraft that incorporates a choke plate that significantly attenuates sidelobes of the antenna beam pattern at elevation angles that would cause RF interference with ground-based terrestrial wireless networks. The choke plate includes a plurality of choke grooves that substantially circumscribe the antenna aperture. The choke plate has an upper surface that is positioned generally coplanar with the upper surface of the antenna aperture. The grooves of the choke plate may be filled with a dielectric material. The choke plate provides a smooth aerodynamic component that significantly attenuates beam scattering, and thus the radiation pattern sidelobes of the antenna at or below the horizon, when the aircraft is in flight.
Abstract:
An object tracking module establishes relationships between different types of data objects associated with application programs while a particular activity occurs. Contextual information associated with the data objects and the activity is collected to establish the relationship. The contextual information may include data objects that are accessed or created while the activity is in progress, or any other information associated with the activity. When an event related to the activity occurs, the object tracking module locates data relevant to the event based on the established relationships. The relevant data is presented in the same information space where the event occurs. A user may easily access the relevant information without manually searching for the data. The object tracking module may determine the degree of relevance between the data objects and the event such that only the most relevant objects are displayed.
Abstract:
A system for validating communications between a plurality of processors is disclosed. The system includes a plurality of loop back paths, and each of the loop back paths is coupled to a corresponding one of the plurality of processors. In addition, each loop back path is configured to attenuate one of a plurality of signals transmitted from each of the corresponding ones of the plurality of processors so as to generate a plurality of loop back signals. A plurality of signal transmission paths are configured to carry a corresponding one of the plurality of signals from one of the plurality of processors to another of the plurality of processors, and a plurality of comparators compare the plurality of loop back signals to the plurality of transmission signals so as to enable the validity of each of the plurality of signals to be assessed.
Abstract:
An auxiliary system for cooling a spent nuclear fuel pool through a submersible heat exchanger to be located within the pool. In each train or installation, a single loop or series of loops of cooling fluid (e.g., sea water or service water) is circulated. The system is modular, readily and easily installed during an emergency and can be self operating with its own power source. Multiple trains may be used in parallel in order to accomplish the required degree of spent fuel pool cooling required.
Abstract:
Architecture for emphasizing changes in collaborative or shared documents. A user can now quickly see what content was changed (hence, unread content) since the last time the user viewed the document or page. A tool automatically tracks and annotates the new content and author of the content for collaboration users. The architecture provides author highlighting on a page or document, which is turned on automatically when the user goes to the page or document. Widgets are displayed in association with the unread content that indicate which user authored all or portions of new unread content. Synchronization of the content update document content so that other users can readily see what is new and the author. A master file is created that stores the emphasis information and associated author information. The file can be stored at any location that is accessibly by the collaborative clients.
Abstract:
Content that is received by an application is delivered to a default location that may be dynamically updated. This default location for content may be updated without interfering with the functionality of a process or application that interacts with the default location. An API allows processes to request the current location of default location and then send and access content at the default location. A user interface allows a user to change the default location within a file system. The default location may be local to a computing device or remote from the computing device.
Abstract:
An apparatus and method for winding a towpreg having a spool winding machine having a rod-shaped body for mounting a core of a spool, wherein the core is shuttled on the rod-shaped body to allow the towpreg to maintain a straight path substantially normal to an axis of the rod-shaped body are disclosed.
