Off-site factory built structure employs a chassis including two interior longitudinal beam members joined at their ends to a perimeter structure. A floor system is integrated within the chassis perimeter. A ledger member is fixed to the inner surface of each longitudinal perimeter member so that a top surface lies in a plane coincident with top surfaces of the interior longitudinal beams. Lateral members are coupled to the tops of the interior longitudinal beams and to the top of the ledger members. The lateral members include secondary stiffening members such as C-channel members, metal Z-channel members, or other metal members of similar structural capacity, spaced apart from each other by a maximum distance S, related to the width of the floor system W, by the equation:

S 12−½W.

The apparel is an athletic garment formed from textiles for use as a resistance training tool that works by increasing the fluid resistance such as aerodynamic drag or hydrodynamic drag on an athlete in a predetermined event.

A speaker enclosure including a compact quarter wavelength transmission path in the shape of a closed spiral that expands radially outward from a centrally located loudspeaker mounting location. The height of the transmission path has a minimum height that is equal to the height of the basket of the desired speaker. The quarter wavelength transmission path spiral of the provides an aerodynamic path for air flow therein which reduces the turbulence of air flow to a minimum that in turn provides even resistance to the air flow within the transmission line (Exhale vs. Inhale).

This new invention is a frame and servo assembly for attaching to massage chair seats manufactured without an existing servo assembly. It includes a frame body, on which there is sliding rack, a screw drive, a positioning stabilizer bar, and a connecting plate. The sliding rack is coupled to various motor brackets, the screw drive, a driving block, a screw drive stop block, and a plurality of wave shaped massaging wheels. The various motor brackets are coupled to two motors. One of the motors utilizes an axle with an off-center axis on both ends. There are multiple connecting brackets installed on the off-center axle, with wheel brackets installed at the end of the connecting brackets. Various “wave” shaped wheels at the end of the wheel brackets aid to simulate the natural feel of human hand joint movements to a user. At the two ends of the additional motor assemblies are bases for joint assemblies. These joint bases are connected to the connecting brackets via connecting joints. The wheels are located on the two ends of the sliding rack. The positioning stabilizer bar is affixed inside the frame body for stability.

Adjustment in the elevation of a user's forearm via adjustment of the actuator arm is provided. The actuator arm includes an adjustable elbow cup and adjustable hand grip. The device does not store potential energy or produce sufficient momentum to oppose a user's immediate and safe termination of motion.

The invention relates to a method for producing a steel tube, wherein a steel sheet (4) is formed into tubular body (1.2) having a round cross section in a bending process (a), welded in a subsequent welding process (b) along the longitudinal edges facing each other for producing a continuous longitudinal seam, and then subjected to a stress-relieving treatment. The production quality is improved, with reduced production time, in that the stress-relieving treatment is performed in a process (c) for concentrically truing along the circumference in at least one segment relative to the longitudinal axis thereof, while cold forming by compression (FIG. 1). The mechanical technological properties of the material are also thereby improved.

An adjustment device includes a casing to which a movable member and two positioning members are movably connected. Two links are connected between the movable member and the positioning members. Each positioning member has a magnetic member connected thereto and the flywheel has a magnetic operation face. When the movable member moves from a second position to a first position, the links drive the positioning members and the magnetic members from a close-to-center position to an off-center position, and the flywheel cuts the magnetic field of the magnetic members to generate a first resistance to the driving device and the flywheel. When the movable member moves from the first position to the second position, the positioning members and the magnetic members move from the off-center position to the close-to-center position to generate a second resistance that is different from the first resistance.
