Abstract: A reaction arm for use with a torque generating device, the reaction arm including a reaction bar, and a body portion having a first internal diameter, and having formed on an internal surface thereof a female spline having a second internal diameter and a guide bushing having a third internal diameter, the first, second, and third internal diameter being distinctly sized.

Abstract: Embodiments of a solid free form printer and a discrete deposition head are disclosed. The solid free form printer may include one or more discrete deposition heads. A discrete deposition head includes a feeder configured to feed a target material in solid form to a deposition assembly. The deposition assembly is configured to create a deposition piece from the target material and dispense the deposition piece onto a portion of the printed object, wherein the deposition piece is in solid form within the deposition assembly. The discrete deposition head also includes a target heat source that heats the portion of the printed object where the target material is to be placed.

Abstract: A portable rolling massager is provided that includes a spindle, a roller rotatably mounted on the spindle, and a covering for the roller that features a comfortable surface when applied to the skin and pressure is applied to muscles underlying the skin. Heating and cooling of the cover provides other therapeutic benefits. Storage in the spindle accommodates weights, flashlights, key storage, music devices, and the like. Hand grips having distal ends are designed to provide the ability to massage trigger points that develop in the muscles.
