A therapeutic, fitness, and sports enhancement device which includes a cylindrically shaped body having a predetermined density and predetermined diameter, the body including a plurality of projections of a predetermined shape. One or more of the predetermined density and the predetermined diameter in combination with the predetermined shape of the projections optimize mobilization of soft tissue structures of the human body.

The present disclosure is directed to a rotor blade assembly for a wind turbine having a first rotor blade segment with a first spar cap segment and a second rotor blade segment with a second spar cap segment. The first and second spar cap segments are arranged together at an interface and are constructed of a composite material. Further, the rotor blade assembly includes a joint assembly at the interface of the first and second spar cap segments. The joint assembly is constructed of a first metal joint secured to the first spar cap segment and a second metal joint secured to second spar cap segment. Moreover, the first and second metal joints are welded together at a weld area.

A method for manufacturing a thermoplastic composite product includes: providing a first and second thermoplastic composite component made from a consolidated stack of thermoplastic composite plies, said first and second component having a first and second ply drop off, respectively. The first and second components are positioned such that the first ply drop off and the second ply drop off are aligned, and the first and second components are fixedly connected by means of heating. The stacks of plies for the first and second components are constructed by stacking the plies in a stacking direction wherein the plies are arranged such that plies at a different position along the stacking direction are laterally offset relative to each other for the purpose of forming the first ply drop off and the second ply drop off, respectively, before consolidating.
