Abstract: A boat, having a transom, includes one or more aft-facing seats. Each aft-facing seat is positioned proximate to the transom and includes a seat bottom that is inclined at a downward angle in a direction extending from aft to fore, a seatback, a headrest, a seat support structure having at least one hidden compartment therein, and at least one pivot mechanism attached to the seatback and the headrest and configured to allow the seatback to move between a first position in which the seatback is capable of supporting the back of a person seated in the seat and a second position in which the seatback is pivoted upwardly to allow access to the compartment and the headrest to move between an upright position and a folded position. A plurality of handles may be provided for each aft-facing seat, with one at an outboard side and another at an inboard side.

Abstract: Golf clubhead (1) made from metal, having a strike face (2) which has a loft angle &agr; of greater than 45°°, said strike (2) face having has a plurality of parallel grooves (10), characterized in that the strike face (2) has a surface roughness Ra of less than 0.25 micrometre, and in that the Vickers hardness of the strike face (2) is greater than 5 GigaPascal.

Abstract: A cosmetic procedure for hair transplantation is carried out with an apparatus (50) comprising a magazine (52) with a plurality of compartments (53) each containing a sample of de-epithelialized tissue having at least one hair shaft attached to a hair bulb. The magazine (52) is loaded in an apparatus (50) having a tapered hollow lumen (57) aligned with a pusher rod (56). With the hollow lumen (57) penetrating a recipient graft site to a predetermined depth and the pusher rod (56), the hollow lumen (57) and a compartment (53) in axial alignment, pusher rod (56) moves through compartment (53) and into the hollow lumen (57) to deposit a portion of donor tissue in the recipient graft site.

Abstract: A releasable tool holder (75) for quickly interchanging tools usable by a conventional robot (50) having one or more articulatable arms (60, 65, 70). The tool holder (75) is mounted to an arm (70) of the robot (50) and is provided with a plurality of variable fulcrum clamping levers (110) capable of engaging a surface (215) of a ring (205) mounting a preselected tool. A fluid motor (95) is connected to a translatable center link (105) that is pivotably attached to the variable fulcrum clamping levers (110) whereby when the motor (95) causes the link (105) to translate, the variable fulcrum clamping levers (110) engage the surface (215) of the tool mounting ring (205). A novel tool mounting ring (205) and a releasable fluid coupling (125) are also provided.
