Abstract: A method for seismic surveying comprises deploying a plurality of seismic receivers proximate an area of subsurface to be surveyed. At least one seismic energy source moves in a path that circumscribes a center, wherein positions of the plurality of seismic receivers remain fixed. At least one of a distance between the path and the center changes monotonically as seismic energy source traverses the path, or the center moves in a selected direction as the seismic energy source traverses the path. The source is actuated at selected times as the at least one seismic energy source traverses the path, such that a spacing between positions of the source along the source path and transverse to the source path varies between successive actuations of the source. Seismic energy is detected at the plurality of seismic receivers resulting from actuating the at least one seismic energy source.

Abstract: The present invention is directed towards group communication enabled tool tips in software application programs that allows the content of tool tips to be created, extended, and modified by users of the group. This invention advances the common practices of providing software users with context sensitive advice on parameter selection to encompass one or more interactive threads of group communication such as social media conversation. The invention is applicable to software programs whether executed locally or executed remotely and delivered to the user through a browser or remote server window.

Abstract: Method and system for improving azimuth distribution. The system includes plural streamers towed by a streamer vessel; a central source towed by the streamer vessel; first and second front sources located in front of the plural streamers along a traveling direction of the streamer vessel; and first and second tail sources located behind of the plural streamers along the traveling direction. The offset distance between the first and second tail sources, along a cross-line direction, is larger than an offset distance between the first and second front sources.

Abstract: Methods and systems are disclosed for delivering content to users. In one embodiment, a computer system obtains text associated with a content item, where the text comprises: text from a transcript associated with a content item, when available; text from a web feed (e.g., an RSS feed, etc.) associated with the content item, when available; text from a webpage associated with the content item, when available; and text that is returned from a call to an application programming interface (API) of a provider of the content item, when available. The computer system then determines a set of entities based on the obtained text.
