Abstract: A swim training apparatus has been designed to help swimmers of any age or any type of experience by teaching the right swimming techniques, correcting their swimming bad habits, and enhancing their swimming capabilities. The apparatus is destined to be used under water in a swimming pool or in a natural basin of water and it consists of a plurality of under water steps which are equipped with reference markers.

Abstract: A device is provided to support and position a limb extremity in a desired steady position to enable acquisition of morphological data from the underside and the upper portion of the limb extremity in a substantially non-weight-bearing attitude. The device comprises a stretchable envelope, made of a thin elastomeric membrane, and a support provided with adjustable positioning members such as hooks, pegs or clips comprising a proximal end and a distal end. The envelope is provided with laterally extending positioning member engaging portions disposed on opposite sides along the longitudinal axis of said envelope. Said positioning member engaging portions receive the distal end of said adjustable positioning members and thereby enable adjustable support and positioning of the envelope and, in turn, of the limb extremity inserted therein.

Abstract: An articulated footrest assembly for a seating unit comprises a footrest member moveable between a retracted position and an extended position, a telescopic linkage for extending and retracting the footrest member between the retracted and extended positions, and an actuating linkage. The footrest member comprises proximal and distal portions while the telescopic linkage comprises a stationary support member mounted to the seating unit, a first telescoping arm, and a second telescoping arm. The first telescoping arm has a distal end connected to the proximal portion of the footrest member through a first pivot. The second telescoping arm has a distal end connected to the footrest member between the proximal and distal portions through a second pivot spaced apart from the first pivot. The actuating linkage comprises a first linkage portion interposed between the stationary support member and the first telescoping arm and a second linkage portion interposed between the first and second telescoping arms.
