A follower apparatus mounted on a track running parallel to an axis of rotation of a spool. The apparatus has a base with a roller mounted thereon and having an axis of rotation parallel to the rotational axis of the spool, the roller providing support and guidance to the material being wound. A pulley is rotatably mounted to receive material from the roller and redirect the direction of material traveled. Light beams and detection apparatus are positioned to detect material excursions to pre-determined off center portions of the roller. The follower positioning apparatus responds to signals detecting the material by repositioning the follower to place the material back on to a center zone of the roller.

An apparatus for transferring material winding between spools. The apparatus includes spindels for positioning first and second spools in a co-planar arrangement with parallel axes of rotation. With the material initially secured to the base of a first spool with tape, a winding mechanism is energized to turn the spools. When the first spool is filled, a first sheave directs the incoming material to the second spool which is rotated at the rate of material supply. A tape applicator is then directed to apply a section of tape over the material, pressing it against the base of the second spool. A small wire is included on the base of the tape being applied. The applicator force on the wire against the material is designed to be sufficient to sever the material, separating the material on the first spool from the material being wound on the second.

A watering can includes a pump and a snorkel which can be used to draw water out of a vessel and into the watering can. The snorkel device is put into a vessel from which water is to be evacuated and the pump is cranked in order to start the flow of water from the vessel and into the reservoir of the watering can. In some embodiments, the pump is a peristaltic pump which includes a mode where the pump is fully disengaged and fluid may flow freely from the snorkel, through the pump, and into the reservoir of the watering can. This allows the operator to use the pump to start a siphoning process which evacuates the remainder of the water from the vessel without further pumping. When not being used to draw water out of a vessel, the watering can may be used in the ordinary manner.

A power generating leg, configurable to be coupled to a person's lower limb, comprising a thigh link, a shank link, a knee mechanism, a torque generator, and a power unit. The knee mechanism is connected to said thigh link and said shank link, and configured to allow flexion and extension movements of said thigh link and said shank link relative to each other. The torque generator is configured to generate torque between said shank link and said thigh link. The power unit is coupled to said torque generator, and configured to cause said torque generator to generate torque. When said power unit is in a power regeneration mode, said power unit causes said torque generator to generate a torque that opposes the angular velocity of said thigh link and said shank link relative to each other and said power unit converts a portion of the power associated with the product of said torque and said angular velocity of said shank link and thigh link relative to each other into electrical power to be stored in a storage device.

A lower extremity exoskeleton, configurable to be coupled to a person, comprises two leg supports configurable to be coupled to the person's lower limbs and configured to rest on the ground during their stance phases. Each leg support comprises a thigh link, a shank link, and two knee joints. Each knee joint is configured to allow flexion and extension between the respective shank link and the respective thigh link. The lower extremity exoskeleton also comprises an exoskeleton trunk configurable to be coupled to the person's upper body. The exoskeleton trunk is rotatably connectable to the thigh links of the leg supports allowing for the flexion and extension between the leg supports and the exoskeleton trunk. In this exemplary embodiment, the energy required for flexion and extension movement between the shank link and the respective thigh link of a leg support over a cyclic knee motion is provided by the person.

The lower extremity exoskeleton comprises two leg supports connectable to person's lower limbs and configured to rest on the ground during their stance phase. Each leg support comprises a thigh link and a shank link; a knee joint configured to allow flexion and extension between the shank link and the thigh link. The lower extremity exoskeleton further comprises an exoskeleton trunk connectable to the person'supper body. The exoskeleton trunk is connectable to the thigh links of the leg supports allowing for the flexion and extension between the leg supports and the exoskeleton trunk. Two torque generators are coupled to each of the knee joints. A power unit, capable of providing power, is coupled to the torque generators. In operation when a leg support is in a stance phase and climbing a slope or stairs, the power unit injects power into the respective torque generator thereby extending the respective knee angle. When a leg support is in stance phase and not climbing a slope or stairs, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to resist flexion of the respective knee joint.

A semi-actuated above knee prosthetic system, which is mostly passive in nature and includes a shank link coupled to an artificial foot, a knee mechanism connected to the shank link and a thigh link attached to an above-knee remaining lower limb of an amputee, is operable in either an actuated mode or an un-actuated mode controlled by a signal processor linked to various prosthetic mounted sensors which may include combinations of knee angle, stance, thigh angle and shank angle sensors. Power is delivered through an electric motor connected to a battery source and employed to drive a hydraulic pump which is part of an overall hydraulic power unit including the torque generator. A signal processor selects a swing state from at least forward, combination forward and descent, combination forward and ascent, reverse, combination reverse and descent, and combination reverse and ascent swing states.
