Abstract: A trailer hitch system for a vehicle such as a car, truck, or SUV, and trailer comprising an overcab portion substantially parallel to a roof of the truck. The overcab portion comprises a roof connector located generally equidistant from either lateral side of the roof and is aligned with a door pillar, and a hitch for connecting the trailer. The overcab portion further comprises a forward frame portion extending from the overcab portion with a forward frame connector and a rearward frame portion extending from the overcab portion with a rearward frame connector, both of which connect to the frame of the vehicle.

Abstract: The present disclosure provides a helmet for a user's head, comprising a shell configured to at least partially surrounds the user's head, an energy-absorbing layer, and a plurality of collapsible modular elements that are individually removably attached to and detached from the helmet. Collapsible modular elements, as used herein, are elements attached to the helmet that collapse or otherwise crush and permanently deform or to temporarily deform upon receiving an impact force of a particular pre-determined amount. By collapsing, energy from the impact is more effectively absorbed instead of being transferred to the user of the helmet.

Abstract: The present disclosure is directed to a barrel comprising cast metal, composite or plastic for use in a bat assembly; a bat assembly comprising a barrel portion, an end cap and a handle; and a ball bat. The barrel may have uniform wall thickness or may include structural elements disposed on an inner surface to improve stiffness and reduce weight. The barrel and bat may further comprise a weighted insert for an asymmetrical center of gravity, allowing controlled spin to be imparted on a struck ball based on the angular orientation of the bat.

Abstract: A golf club head in accordance with various aspects of the present invention, may have a higher volume and/or higher strength. The golf club head may also comprise a variously configured and/or detachable face, allowing various faces of differing materials to be attached to the body. A detachable face further allows the head to be tuned via placement/rearrangement of weights within the head to change the center of gravity and moment of inertia.

Abstract: An optimized composite bow limb is provided wherein the bow limb is composed mainly of thin sheets of resin impregnated laminates. In a method for making the composite bow limb, laminates are selectively distributed throughout the limb so as to aid in equalizing the stress throughout the working area of the limb and so as to increase the stiffness in the fork section of the limb. The laminates are layed up as part of a bundle in a mold such that some portions of the bundle have more fabric weaves than other portions of the bundle, and thus have increased thickness. The desired thickness of the limb is defined such that the fork portion has an increased thickness to provide increased stiffness for the tines.
