Abstract: A movement detection device includes a signal transmission device configured to transmit a radar signal transmission toward a target area and to receive reflected radar signals, and a signal analysis device configured to analyze the reflected radar signals to detect a movement in the target area that is indicative of micro-shivering. In response to detecting the micro-shivering, the movement detection device generates an alarm.

Abstract: A device that is ergonomically designed for steering a variety of industrial vehicles is disclosed. The driver may steer the vehicle while keeping his hand flat on the device, which is custom fitted to a particular industrial vehicle. The hand that steers the vehicle is kept flat on the device, allowing the driver of the vehicle to steer it without grasping the steering wheel.

Abstract: The perforations of a pre-perforated tubular are plugged with interior protruding, mostly hollow plugs which temporarily seal the perforations. The plugs are capable of withstanding a significant pressure differential and, when combined with an insert, forming a flotation cavity containing a buoyant fluid. The temporarily sealed tubular is then run into a wellbore, the tubular is set, and the plugs are unsealed. The unsealing is preferably accomplished by drilling out the interior protruding portions. Solid baffles may also be placed in the string to limit buoyant fluid loss in the event of premature unsealing in another embodiment of the invention.

Abstract: A hydraulic setting and release system for run in and cementing of a work string and tubular within a borehole has a small diameter pipe string extending from a release tool through a packer to within the tubular. The system forms at least one annulus between the pipe string and tubular. The pipe string includes a ported nipple and a seat subassembly downstream of the ported nipple. The pipe string allows the packer to anchor the tubular, by being inflated through the port even when the seat is blocked. The pipe string also forms a flotation annulus which is sealed by, and the pipe string is supported by, a drag/seal subassembly downstream of the seat assembly. The system also includes a safety release tool for reliable uncoupling. Uncoupling is accomplished after run in, displacing a cement slurry slug separated by a plug or dart using a following pump down fluid which can land on the seat and block further flow and displacement of cement slurry, and anchoring.
