Systems, methods, and computer program products which facilitate the ability of a user to monitor and assess the location of and forces transferred to various joints, muscles, and limbs and their relative positions at each and every moment during normal daily activities, training loads of an exercise, or a competitive or high intensity athletic endeavors, in order to mitigate and reduce the risk of injury as well as to track fitness performance elements are disclosed. In an aspect, systems, methods, and computer program products are disclosed which utilize at least one sensor in order to capture a user's movement information during various tasks and exercises. This movement information may then be analyzed in order to determine quantifiable values for the user's likelihood of experiencing an injury and/or the user's overall fitness, generally. The systems, methods, and computer program products of the present disclosure may also be used to measure a user's neuromuscular efficiency and help the user make improvements thereto.

A quick install skateboard hanging device designed to lower damage to the wall, the skateboard deck, and the graphic design on the skateboard deck. The hanger is configured to allow small adjustments to the positioning after the first installation. Hanger device includes a base, a set of pins, and a set of adhesive or hook and loop strips for attaching the base to the wall. In one embodiment, the device has a cradle and a ball adapter, wherein the ball adapter is attached to the base and the cradle is removably fastened to the ball adapter, the ball adapter is positioned between the base and the cradle, wherein clamps of the cradle are extendable to accommodate skateboard of different sizes.

A modular accessory system for altering surface topography on boards, handles, and other contact platforms used in sports, fitness, and consumer applications. The system comprises attachable elements that vary in shape, texture, height, or material and are positioned in contact zones to modify grip, traction, slide, or tactile feedback. Elements are secured via adhesives, fasteners, magnetic couplings, hook-and-loop systems, or UV-curable resins. The system supports modular customization across diverse platforms, including but not limited to sporting equipment, recreational boards, tools, gaming devices, fitness gear, and wearables. Users can selectively place, reposition, or replace accessories to suit maneuvers, ergonomic needs, or training goals. Optional inserts or embedded electronicssuch as sensors, lights, or hapticsenable real-time feedback, interactivity, or performance tracking. The system allows post-manufacture integration and interchangeable use across platform types, transforming passive surfaces into adaptive, performance-enhancing, and feedback-capable interfaces for training, recreation, rehabilitation, or interactive use.
