Abstract: An ice crampon designed to be attached to a footwear item includes a front portion which has at least one pair of front tips; a rear portion which has at least one pair of rear tips; at least one flexible link which connects the front portion and the rear portion to each other; and at least one intermediate portion which is mounted on the flexible link by being positioned between the front portion and the rear portion. The at least one intermediate portion has at least one pair of intermediate tips. The pairs of front tips, rear tips, and intermediate tips are configured to prevent the ice crampon from sliding on ground, particularly on frozen ground. The front portion, the rear portion, and the intermediate portion are articulated independently of each other, and the position of the intermediate portion are adjustable in relation to the flexible link.

Abstract: A chlorine generator apparatus wherein a housing is adapted to be mounted in an exterior, user-accessible surface of a spa and a chlorine generating electrode cartridge carrying a pair of electrodes is configured to be installable by a user in the housing and to thereafter be removeable by the user for replacement.

Abstract: One embodiment of the present invention relates to an assisted braking belay system with a housing, camming mechanism, and clutch mechanism. The housing may include a substantially enclosed rope channel through which a rope may extend to the climber. The camming mechanism is moveably coupled to the housing and configured to automatically engage a camming surface upon the rope across the rope channel if the rope translates through the channel at a particular acceleration rate. The clutch mechanism may function as a secondary locking mechanism to engage the camming surface of the camming mechanism upon the rope across the rope channel.

Abstract: An automatically locking carabiner system including a frame, a gate, a gate biasing system, and a gate locking system. The frame and gate form a continuously enclosed inner region in a closed configuration with respect to the frame. When in an engaged state, the gate locking system is configured to automatically lock the gate in the closed configuration with respect to the frame. The gate locking system may include a trigger coupled to the frame such that the position of the trigger corresponds to the state of the gate locking system. The trigger may be positioned on an opposite side of the frame from the gate with respect to the inner region. The force required to disengage the gate locking system may be substantially opposite that which is required to transition the gate to the open configuration with respect to the frame.

Abstract: One embodiment of the present invention relates to an assisted braking belay system with a housing, a camming mechanism, and a lever mechanism with a lever disengagement mechanism. The housing may include a substantially enclosed rope channel through which a rope may extend to the climber. The camming mechanism is moveably coupled to the housing and configured to automatically engage a camming surface upon the rope across the rope channel if the rope translates through the channel at a particular speed. The lever mechanism enables a belayer to selectively disengage the camming mechanism and release the camming surface from the rope thereby allowing the rope to translate through the rope channel. The lever disengagement mechanism is configured to automatically disengage the lever mechanism from the camming mechanism thereby enabling the camming mechanism to automatically reengage the camming surface upon the rope across the channel.

Abstract: One embodiment of the present invention relates to a user based carrying system capable of independent transportation of a load including a hip-based user attachment system. The carrying system includes an enclosure member having an internal region encased by an internal surface. A user attachment system releasably secures the carrying system to the user for independent transportation without requiring muscular engagement. The user attachment system includes a hip attachment system with a dorsal articulation member and a strap member. The dorsal articulation member includes a front and rear member three-dimensionally moveably coupled to one another. The rear member is coupled to the enclosure member and the front member is coupled to the strap member. The three-dimensional moveable coupling between the front and rear members includes three restricted degrees of freedom configured to efficiently absorb corresponding user hip movements and directly support other user hip movements.

Abstract: An adjustable support assembly for an orthopedic brace has a support arm, a housing and a locking mechanism. The housing includes a travel track which slidably receives the support arm. The locking mechanism includes a lock lever which selectively applies a sufficient force to the support arm to prevent slidable displacement of the support arm in the travel track.

Abstract: A hinge for an orthopedic brace has two rotation plates, a pivotal connector connecting the rotation plates, a rotation limiting mechanism, and a rotation locking mechanism. The rotation limiting mechanism includes a rotation limiting face formed in one of the rotation plates and a rotation limiting assembly which has a stop face engageable with the rotation limiting face upon rotation of the rotation plates in a given direction to limit further rotation in that direction. The rotation locking mechanism includes a series of lock notches formed in one of the rotation plates and a rotation lock pin positionable within one of the lock notches to lock the rotation plates in a fixed position.

Abstract: A hinge is provided for an orthopedic brace having a first rotation plate, a second rotation plate, a pivotal connector connecting the first and second rotation plates, a rotation limiting mechanism, and a rotation locking mechanism. The rotation limiting mechanism includes a rotation limiting face formed in the peripheral edge of the second rotation plate and a rotation limiting assembly selectively positionable in a fixed position relative to the first rotation plate. The rotation limiting assembly has a stop face engageable with the rotation limiting face upon rotation of the first and second rotation plates, which limits further rotation in a first rotation direction. The rotation locking mechanism includes a rotation lock pin and a series of lock notches formed in the peripheral edge of the second rotation plate.
