Abstract: A fireplace system can comprise a firebox and a heat exchanger. The heat exchanger may be in fluid communication with ambient air and may comprise an inlet configured to draw air into the front of the heat exchanger. Operation of a fireplace system comprising a heat exchanger may produce airflow through the heat exchanger by natural convection. The airflow through the heat exchanger may reduce heat transmission from the firebox and the fireplace system.

Abstract: A fireplace system can comprise a first safety barrier and a second safety barrier disposed across a firebox opening and defining an interbarrier space. A fireplace system can also comprise a heat exchanger in fluid communication with the interbarrier space. The interbarrier space and heat exchanger may further be in fluid communication with ambient air. Operation of the fireplace system may produce natural convection through the interbarrier space, resulting in cooling of the safety barrier and the fireplace system.

Abstract: A well-logging tool may be positioned within a borehole of a subterranean formation. The well-logging tool may include a housing having an interior defining a dual-detector receiving chamber extending longitudinally, and having first and second portions, and a first azimuthal radiation detector carried by the first portion of the dual-detector receiving chamber. The first azimuthal radiation detector may include a first gamma-ray detector and a first photodetector associated with the first gamma-ray detector. The well-logging tool may include a second spectral radiation detector carried by the second portion of the dual-detector receiving chamber. The second spectral radiation detector may include a second gamma-ray detector and a second photodetector associated with the second gamma-ray detector.

Abstract: Systems and methods are disclosed that provide a flexible file capable of storing rich content. A flexible file may include a section object, one or more tile objects stored within the section object, and one or more clip objects associated with each tile object. A clip objects may store a content item. Alternatively a clip object may store one or more references to a content item, the content item being stored externally to the flexible file. The disclosed flexible file allows an application to adjust the atomicity based upon the needs of a user or application.

Abstract: Methods and systems are provided for dynamically configuring document solutions and for obtaining desired or required components of such document solutions for use with computer-generated documents. If a document is associated with a document solution, a request for components of the solution is sent to a manifest of document solutions. Identification of a user of the document is also passed to the manifest. At the manifest, identification information for the user is used to query a user database to determine a profile of the user such as the user's job description, location, security clearance, and the like. Based on the user's profile, the document solution is configured dynamically to include solution components most helpful to the particular user. A manifest collection is provided for serving as a repository of document solution location information for many different namespaces (schemas) that may be associated with one or more user documents.

Abstract: A mechanism is provided for embedding an object in a receiving or client document such that a client application may operate on the embedded object to include interrogation and modification of data contained in the embedded object. When a given document object is embedded into a receiving document, data representing the embedded object is saved to a data stream storage for the receiving document. When the embedded object in the receiving document is subsequently requested in response to an operation executed on the embedded object, the receiving application obtains the data representation of the embedded object from the data stream storage. Once the receiving application obtains the data representation of the embedded object, the receiving application may perform operations on the embedded object by accessing the embedded object via its data representation.

Abstract: An application has its own namespace or namespaces and a schema, or a set of schemas, which can be used by applications to generate and/or validate documents in a unique format. The application can uniquely define the format (and properties) of content in a document such that the document is represented in a native format. The document can be stored externally as a markup language file in accordance with the schema of the application. When the format is stored in a markup language, other applications can validate the document stored in accordance with the native format. The other applications can represent the lists in accordance to the degree to which they are aware of the unique properties of the application used to generate the document.

Abstract: Methods and systems are provided for separating the data of a structured document from markup structure applied to the document and for linking the separately maintained data with associated markup structure applied to the document. The data stream in an Extensible Markup Language (XML) represented document is moved outside of the document structure into a data file that is linked to the document structure. The data file and the XML-represented document structure are maintained in association with a single file (e.g., document), but in separate object models. Links are established between XML elements applied to the document and data ranges of the data file. Each of the XML structure file and the data file may be accessed and edited separately without affecting the structure or data of the other file until the two files are merged for presenting the associated document.

Abstract: An open file format is used to structure the features and data within a document associated with a word processing application. The file format simplifies the way a word processing application organizes document features and data, and presents a logical model that is easily accessible. The file format is made up of a collection of modular parts that are stored within a container. The content included in the modular parts are XML that is based on ASCII. The XML schema provides a definitional framework for how the modular parts relate. This content allows tools to interrogate a word processing document to examine and utilize content and ensure that the file is written correctly. Each of the modular parts is capable of being interrogated separately regardless of whether the application that created the document is running. Information may also be changed, added, and deleted from each of the modular parts.

Abstract: Methods and systems provide for breaking a computer-generated document into a number of components where the components have explicit relationships with each other. A relationship representation is generated for the components of the document. A user may then navigate the relationships between the components to quickly understand the nature of the document and its components and to locate particular portions of the document that are important to the user. In addition, the user may open, edit and reuse particular components of the document apart from the rest of the document and without having to open or edit the document.

Abstract: Portions of an Extensible Markup Language document, such as individual paragraphs or groups of paragraphs or fragments of text, are provided self-describing properties such as styles, fonts, list types, and the like. If such a portion of a document is subsequently copied or moved to a second document or to a different location in the first document, the self-describing properties provided for the portion travel with the portion to the second document or to the different location in the first document.

Abstract: The present invention represents header and footer structures in a markup language (ML) document. The ML document may be parsed by applications that understand ML other than the application that generated the ML document. The ML document may be manipulated on a server or anywhere even when the application creating the ML document is not present. The header or footer originally used in the ML document may be manipulated when the ML document is parsed by other applications. Header and footer information (i.e., properties) are saved in a markup language (ML) document without data loss, while allowing the header and footer structures to be parsed by ML-aware applications and to be read by ML programmers.
