Abstract: A control system may include a direct-current (DC) power bus for charging (e.g., trickle charging) internal energy storage elements in control devices of the control system. For example, the control devices may be motorized window treatments configured to adjust a position of a covering material to control the amount of daylight entering a space. The system may include a DC power supply that may generate a DC voltage on the DC power bus. For example, the DC power bus may extend from the DC power supply around the perimeter of a floor of the building and may be connected to all of the motorized window treatments on the floor (e.g., in a daisy-chain configuration). Wiring the DC power bus in such a manner may dramatically reduce the installation labor and wiring costs of an installation, as well as decreasing the chance of a miswire.

Abstract: A non-impact exercise machine which can be used by people of all ages, requiring no special dexterity or athletic ability to perform and exerting minimal impact on the muscles and joints of the user, providing a light weight, collapsible, and affordable indoor exercise machine for simulating walking. One embodiment of the exercise machine comprises a support structure; and, right and left platforms for standing on by the use's right and left foot respectively in an approximately horizontal position; and, right and left linkage assemblies pivotably disposed on the support structure about a right and left upper pivot axis and the right and left platforms, the platforms movable in a fixed path below the right and left upper pivot axis; and, a resistance system for resisting the movement of the right and left platforms.

Abstract: An exercising apparatus for simulating skating and skiing motion in which outward and opposite unilateral movement of the user's feet ultimately drives a momentum storage member which can be a flywheel. The apparatus has a base for supporting a track having left and right distal ends. The track positions and restrains foot carriages to approximately horizontal movement. The foot carriages support the user's feet so that when the user's left foot extends outwardly and to the left of user's body the left carriage moves towards the left distal end of the track, and when the user's right foot extends outwardly and to the right of user's body the right carriage moves towards the right distal end of the track. A driven pulley is supported by the base and drives the momentum storage member. The apparatus has a first subassembly having unilaterally acting first engaging member and first transmission, and a second subassembly having unilaterally acting second engaging member and second transmission.

Abstract: A shock-free exercising machine, which can be used by the young and elderly, the small and large structured person, and the inexperienced and experienced exerciser for both aerobic and anaerobic exercise, that provides a rhythmic fluid motion to the body of the user and particularly to the legs, pelvis and spine which is completely free of shock and impact stress on the joints, bones and muscles in which, at all times, the user remains in an upright standing position. In one embodiment the exercise simulates clinging motion of the user's legs with synchronized push-pull motion of the user's arms.

Abstract: An exercise apparatus which simulates stair climbing, is adjustable to achieve various levels of difficulty and adjustable to accommodate individuals of all heights. The exercise apparatus has a support structure, left and right foot levers pivotally connected to the support structure, a rotatable shaft rotatably attached to the support structure, and left and right clutches drivingly connected to the rotatable shaft. The left and right clutches independently drive the rotatable shaft in a drive-rotational direction when either of the clutches is rotated in the drive-rotational direction. Each clutch overrides the rotatable shaft when rotated in the counter drive-rotational direction. Pulleys or sprockets are mounted on each of the clutches. A rope or chain drivingly engages the pulleys or sprockets and causes their rotation when the foot levers are moved. A worm gear, which is driven by the rotatable shaft, is part of a resistance assembly mounted on the support structure.

Abstract: An exercise apparatus having a unique support frame including a base, a first upwardly extending member having a handgrip mounted on its upper end, and a second buttress member extending from the base to a point between the ends of the first member. A pair of foot beams pivotally mounted on one of the upwardly extending members. A rope interconnecting the foot beams and extending over a pully mounted on the support frame above the foot beams, a pair of shock absorbers pivotally connected to the foot beams at one end and connected to the support frame at a point above the foot beams at their other end.

Abstract: In a preferred embodiment the full body, shock-free exercising machine of this invention comprises a base member; a vertical frame member fixedly attached to the base member, right and left lower levers pivotally mounted on the lower part of the vertical frame member, the free ends thereof being operable for standing on by users; right and left upper levers pivotally mounted on the upper part of the vertical frame member; right and left tie rods pivotally mounted at the upper distal ends thereof to the right and left upper levers, respectively, and pivotally mounted at the lower distal ends thereof to the right and left lower levers, respectively, such that rotation of the lower lever on either side of said machine in one direction causes rotation of the upper levers on the same side of the machine in an opposite direction rocker arm for synchronizing the movement of the lower levers, the rocker arm being operable when one of the lower levers is moving downwardly to cause the other one of the lower levers to
