Abstract: The automatic diving tending system (ADTS) includes a buoyant sealed torsional apparatus having a plate with a perimeter seal to which is affixed a cover with a perimeter flange forming a dry buoyant cavity. On the plate is mounted a bridge supporting a drive shaft, a locking mechanism, a constant torque spring motor, and an overdrive transmission linkage. A tether spool apparatus is mounted on the exterior bottom side of the plate. It includes a frame with a guide, a spool, and coaxial connecting structure that connects to the drive shaft. A line wound on the spool that is pulled off tightens the spring motor, enabling the full length of the line to be rewound back onto the spool and to be stopped at any time by a diver.

Abstract: A force feedback cuff system, method, and apparatus may include receiving force feedback signal from an external, remotely controlled device; processing the force feedback signal to determine a correlated amount of pressure; applying a correlated signal to air pump equipment to inflate or deflate an inflatable cuff on an operator; and continuing the receiving, processing, and applying while the operator controls the external, remotely controlled device to provide haptic feedback to the operator in an intuitive and non-obtrusive fashion.

Abstract: A tool sled having a body with a concave top surface and a convex bottom surface is provided and includes a flat plate and a handle. The bottom surface is symmetric about a transverse axis and passes through the body in a direction perpendicular to a direction of movement of the sled. A flat plate in contact with the top surface along two contact lines runs across the concave surface where each contact line is parallel to the transverse axis. A handle attached to the body extends upwardly from the top surface and outwardly from the body along a longitudinal axis parallel to the direction of movement of the sled.
