An isokinetic oscillation exercise device of an elongated flexible blade having a first and second end and a grip portion coupled to a middle portion of the elongated flexible blade. End caps coupled to said first and second ends adapted to storage. Further, a method is disclosed of manufacturing an isokinetic oscillation exercise device that provides a flexible elongated flexible blade, a grip portion injection molding, a pliable ring injection moldings, and end caps injection molding; slides the pliable rings on the elongated flexible blade separated by a length of the grip portion, overmolds a first-shot of the grip portion over the pliable rings, overmolds a second-shot of the grip portion to the first-shot of the grip portion to the elongated flexible blade, seals the first-shot to the second-shot of the grip portion against the pliable rings; and attaches the end caps to the elongated flexible blade.

The present disclosed subject matter relates to a method for producing a composite component, in particular for a gliding board, roller board or skateboard. The method comprises introducing a bottom mat made of reinforcing fibers, above this a flat core made of plastic, and above this a top mat made of reinforcing fibers into an opened mold, closing the mold, introducing an uncured plastics matrix into the closed mold, allowing the plastics matrix to cure in the closed mold, opening the mold, and demolding the composite component. The core is provided on its lower and upper sides with a plurality of spacer nubs, which keep the bottom and top mats in the closed mold at a distance from the lower and upper sides.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A hockey-stick blade includes a heel region, a toe region spaced longitudinally from the heel region, and a mid-region located between the heel region and the toe region. The toe region includes one or more reinforcing elements, optionally of different lengths, located at different vertical positions within the toe region. The blade further includes a hosel that optionally is tailored to substantially match the strength and stiffness characteristics of an attached or integral hockey stick shaft. The mid-region of the blade exhibits improved feel and flexibility characteristics due to the increased stiffness in the toe region.

Methods for manufacturing articles of footwear are provided. In various aspects, the methods comprise utilizing additive manufacturing methods with foam particles. In some aspects, the additive manufacturing methods comprise increasing the temperature of a plurality of foam particles with actinic radiation under conditions effective to fuse a portion of the plurality of foam particles comprising one or more thermoplastic elastomers. Increasing the temperature of the foam particles can be carried out for one or multiple iterations. The disclosed methods can be used to manufacturer articles with sub-regions that exhibit differing degrees of fusion between the foam particles, thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
