Abstract: A method and apparatus for imparting continuous passive motion to one or more joints, ligaments, or tendons is disclosed. The apparatus has a housing, an actuator, and a flexion/extension assembly. In preferred form, a main flexion cable links the actuator to a joint support member pivotally attached to flexion/extension assembly. Reciprocating motion of the main flexion cable causes the support member to oscillate. A restoring force, preferably a second main cable cooperative linked to the actuator, is present so as to urge the support member to its initial position. The path of motion of the support member can be altered, while the apparatus is in operation, by a cable deflecting assembly. By controlling the degree of cable deflection, the degree of support member motion can be altered. Variations to the apparatus include providing for multiple flexion cables, each linked to the main flexion cable, and multiple cable deflecting assemblies; a cable deflecting assembly associated with the second main cable for controlling the degree of extension; and a heat source affecting the area surrounding the flexion/extension assembly.

Abstract: A portable ice rescue craft includes a plurality of locking raft sections that are foldable for storage and transport. A drive unit includes a drive wheel driven by an electric motor via a drive belt. The drive wheel may include a plurality of spikes configured to engage ice and a plurality of paddles that are centripetally urgeable outward to pull the rescue craft through water. A forward raft section may include a pair of outboard pontoons to provide stability and minimize lateral rocking. An aft raft section includes at least one rudder. A pair of rudders may be mounted to a plate on a pivoting, biased system. The rudders automatically fold upwardly when the ice rescue craft is on ice or land. The rudders automatically activate downwardly when the ice rescue craft is in water.
