Abstract: There is provided herein a method of seismic acquisition that utilizes an arrangement of marine sources where each source is positioned at a water depth shallow enough for the surface ghost notch to fall at a frequency greater than or equal to the maximum radiated frequency of interest. If the marine seismic source has a ratio of signal bandwidth to maximum frequency that is less than one half, then it is possible to deploy it at a greater depth at which ghost notches fall below and above its frequency band but not in it. Further, by placing two or more sources at different depths for the same frequency, any undesired nulls in the radiation pattern caused by the deeper tow can be filled in.

Abstract: A user interface event is received by way of a user interface. A software component adapted to process the user interface event may be pushed onto a memory stack, and the user interface event may be processed using the software component on the stack, or with a software component that is not on the stack. The software component on the stack, if used, may then be popped from the memory stack. In addition, a plurality of software components may be pushed onto the memory stack, and in that case, at least one of the components may be selected to process the user interface event. The user interface event is processed using at least one of the plurality of software components, and one or more of the plurality of software components are popped from the memory stack.

Abstract: Embodiments of the present invention relate to methods, systems, and computer-readable media for editing an object displayed by a computer system. Editing comprises detecting an edit operation for an object displayed on a video display of a computer system. An edit operation request is then sent to an abstraction layer via an interface provided by the abstraction layer to initiate editing of the object by the abstraction layer. The abstraction layer receives the edit operation request and determines the type of container in which the object is displayed based on properties related to the object to be edited. The abstraction layer reads a set of properties related to the object and the container in which the object is displayed. The abstraction layer may then edit the object based the properties of the container and object by modifying one or more of the properties of the container and object.

Abstract: An API and method for processing a user interface event is provided. The user interface event may take place in any environment of a software application, and may result from any type of user or software action. An embodiment also provides a framework for customizing the processing of a user interface event without the need to maintain accountability of computer states. In the method, an application process user interface event is processed using an operating system process. A user interface event is received by the application process by way of a user interface. A software component adapted to process the user interface event is pushed onto a memory stack by the operating system process. The operating system process processes the user interface event using the software component, and pops the software component from the memory stack.

Abstract: A system and process for capturing and rendering ink is described. An ink canvas object may contain none, one, or more objects or elements and may specify the z-order of the objects or elements. The ink canvas object may host a variety of objects or elements and, therefore, provide ink functionality to the objects or elements, even though the objects or elements themselves may not have ink functionality.

Abstract: Architecture for validating input. A control is associated with a data source via a Binding. The control is arranged to receive user input with which to update the data source. In addition, zero or more validation rules are associated with the Binding and executed to validate the input. If the user input is invalid or an exception occurs while converting the input or updating the data source, a validation error object may be created and attached to the control. To provide feedback to the user, a control defines additional user interface elements to adorn the control and display the created validation error information to the user.

Abstract: Supply state information associated with a peripheral device that is shared over a network while coupled to a local network resource is obtained and a representation of the supply state information is stored in a data repository that is accessible by remote network resources.

Abstract: Described are collection view objects, which provide a user interface view over a data collection, where each view may have its own sort order, filter and/or grouping criteria, as well as current item semantics. A user interface element is bound to a data collection, such as via markup language (e.g., XAML). At runtime, a collection view object is instantiated as an indirection between the data collection and the user interface element, whereby a collection of data items is viewed according to how each collection view object is currently configured with respect to sorting, filtering and/or grouping. Multiple collection views may be specified on the same data collection, whereby distinct simultaneous views of the data items may be presented in different user interface elements. The collection view object dynamically updates the displayed data as changes are made in the data collection. A current item may be selected within the collection view.

Abstract: Described is a mechanism for providing scoped modular services (SMS) through an API. A common set of services is provided by the API that may be enabled or disabled by each component. The services are managed using a property system in the same manner as element properties are used, such as properties relating to text formatting. This helps to ensure fine control and a high degree of customization for a user interface. The use of the services is not limited to editing in the common sense of the word. The SMS is a mechanism for controlling access to implementation of services contained within a tree of components. Services may also be created by developers that are managed by a service manager along with the common services.

Abstract: A process for making a composite tube uniquely suited for use in ethylene pyrolysis furnaces wherein the tube comprises an outer shell made from a wrought or cast Fe—Ni—Cr heat resistant alloy and an inner core made from INCOLOY® alloy MA956 powder. The outer shell and powder core are heated and simultaneously extruded to form a composite tube. The process is carried out at temperature, and time at temperature, preferably less than 1200° C. so as to prevent recrystalization of the very fine grain structure in the alloy MA956. This un-recrystalized fine grain structure permits pilgering and/or cold drawing of the extruded composite tube to final size. The composite tube provided by the present invention is uniquely suited for use in the petrochemical and chemical process industries, so as to increase the efficiency and productivity of their respective processes.
