Abstract: Geophysical data can be acquired while sailing in a first direction along adjacent lines of a first continuous subarea of a survey area, sailing in a second direction along adjacent lines of a second continuous subarea of the survey area, sailing in the first direction along alternating lines of a third continuous subarea between the first continuous subarea and the second continuous subarea, and sailing in the second direction along each of a second plurality of alternating lines of the third continuous subarea.

Abstract: A motion compensation system for a helipad on a vessel includes a sensor for measuring a parameter related to at least one or pitch and roll of the vessel. The system includes a first actuator functionally coupled to the helipad to move the helipad translationally with respect to the vessel in response to the measured at least one of pitch and roll of the vessel.

Abstract: A telescopic container includes a first enclosure section defining a first interior volume and being open on one side. A second enclosure section defines a second interior volume and is open on one side. The open sides face each other. The second section has exterior dimensions enabling movement thereof into the first enclosure section. A plurality of telescopic units connect the first and second enclosure sections. The telescoping units having operable length such that when fully extended, the first and second enclosure sections are separated from each other and a work surface is defined having an area exceeding a combined surface area of the first and second enclosure sections. The operable length is such that when fully retracted, the second enclosure section is nested in the first enclosure section to define a total interior volume less than the sum of the first and second interior volumes.

Abstract: Devices are disclosed for telescopic containers. In one example embodiment, a device for a telescopic container includes a first portion having a top surface connected to a bottom surface by one or more sides. Further, the device includes a second portion also having a top surface connected to a bottom surface by one or more sides. Further still, the device includes more than one telescopic units, which are located on the top and bottom surfaces of the first and second portions, that expandably connect both the first top surface to the second top surface and the second bottom surface to the second bottom surface. Whether rectangular or wheel shaped, for example, the container may store items in a contracted state, and, in an expanded state, the container transforms into a working surface with an increased surface area as compared to the container in its contracted state.
