Abstract: A method of separating a downhole tubular includes running a tool into a wellbore to a predetermined location on a work string and actuating flow actuated slips. The method also includes maintaining slips in a set position by providing a first upward force on the work string. The method further includes rotating the work string to separate an upper portion of the tubular from a lower portion using a cutter assembly disposed on the work string below the slips and pulling the upper portion of the tubing and the tool from the wellbore.

Abstract: A method for conducting a survey or poll includes receiving authentication data from a plurality of users. The received authentication data is evaluated for each user to determine if the authentication data is valid. In response to determining that the authentication data is valid for a particular user, that user is provided access to a plurality of voting options. Voting information is received from at least some of the plurality of users. The received voting information identifying selected one of the plurality of voting options is analyzed in real time. Voting results are presented to at least some of the plurality of users based on the analyzed voting information.

Abstract: A modular LED grow light system is provided that includes one or more LED grow light modules. Each of the LED grow light modules includes one or more connecting ports and an LED. The one or more connecting ports are configured to connect to another LED grow light module. A power source is connected to one of the connecting ports of the one or more LED grow light modules. The LEDs of the one or more LED grow light modules provide light to a portion of a plant.

Abstract: A foil assembly for a watercraft includes a base assembly, a fin rotatably connected to the base assembly such that the fin can rotate longitudinally, and a slider attachment configured to connect to a fin box of a watercraft wherein the base assembly is configured to be removably disposed within the slider attachment such that the base assembly and the fin can be removed and rotated laterally to a folded position and still be retained by the slider attachment to the fin box.

Abstract: A downhole tool including a tubular body having an upper connection and a lower connection and an axial borehole therethrough, wherein the upper and lower connections are configured to connect to a drilling assembly, at least one expandable component coupled to the tubular body and configured to selectively extend radially therefrom, and an actuation assembly configured to selectively actuate, deactuate, and reactuate the at least one component. A method of selectively actuating a downhole tool, wherein the downhole tool comprises a tubular body with an axial borehole therethrough and at least one component, the method including circulating a drilling fluid in the axial borehole of the downhole tool, actuating the at least one component, deactuating the at least one component, and reactuating the at least one component.

Abstract: A method and apparatus for transcribing composite images. In one embodiment, a method comprises projecting a first image onto a surface, wherein a first coordinate system defines positions within the first image and a second coordinate system defines positions on the surface. The method further comprises forming a second image on the surface by using a stylus, and recording the formation of the second image relative to the first image by periodically detecting the position of the stylus relative to the second coordinate system by receiving and processing signals transmitted from the stylus. The method also comprises translating the position of the stylus relative to the second coordinate system to a position relative to the first coordinate system, and storing the composite image comprising the first image and the second image as machine-readable data.
