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 marine seismic source comprises a housing having a central axis, an open end, and a closed end opposite the open end. In addition, the seismic source includes a piston extending coaxially through the open end of the housing. The piston is adapted to axially reciprocate relative to the housing. Further, the piston has a first end distal the housing and a second end disposed within the housing.

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:
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 marine seismic source comprises a housing having a central axis, an open end, and a closed end opposite the open end. In addition, the source comprises a piston coaxially disposed within the housing. In addition, the source comprises a flywheel disposed within the housing and axially positioned between the closed end and the piston. The flywheel is configured to rotate about a rotational axis. Further, the source comprises a connecting rod moveably coupling the piston to the flywheel. The connecting rod has a first end pivotally coupled to the piston and a second end pivotally coupled to the flywheel. The second end of the connecting rod has a first position at a first distance measured radially from the rotational axis, and a second position at a second distance measured radially from the rotational axis. The first distance is less than the second distance.

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:
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.
