A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).

Systems and methods are described for generating a three-dimensional track a ball in a gaming environment from a single camera. In some examples, an input video including frames of a ball moving in a gaming environment recorded by a camera may be obtained, along with a camera projection matrix associated with at least one frame that maps a two-dimensional pixel space representation to a three-dimensional representation of the gaming environment. Candidate two-dimensional image locations of the ball across the plurality of frames may be identified using a neural network or a computer vision algorithm. An optimization algorithm may be performed that uses a 3D ball physics model, the camera projection matrix and a subset of the candidate two-dimensional image locations of the ball to generate a three-dimensional track of the ball in the gaming environment. The three-dimensional track of the ball may then be provided to a user device.

A ball bat configured for impacting a ball. The ball bat extends along a longitudinal axis and includes a bat frame and a pivot joint. The bat frame includes a handle portion coupled to a barrel portion. The barrel portions has a distal region. The pivot joint is coupled to the distal region of the barrel portion. The pivot joint movably supports the barrel portion relative to the longitudinal axis such that the distal region of the barrel portion may pivot towards and away from the longitudinal axis about the pivot joint.

A method of making a ball bat may include forming a bat frame with a handle and an inner barrel structure, providing spacer elements extending radially outwardly from the inner barrel structure, and forming a barrel shell having a main barrel and a tapered section. An inner diameter in the tapered section may be equal to an outer diameter of a first one of the spacer elements. The method may include mechanically locking the barrel shell to the bat frame by passing the handle through the barrel shell and moving the barrel shell toward the inner barrel structure until the barrel shell contacts the first one of the spacer elements. A gap is maintained between an outer diameter of the inner barrel structure and the barrel shell. The barrel shell may deflect during a hit to create a trampoline effect, while the inner barrel structure limits the deflection.

Embodiments of golf gloves having a cut out portion and methods to manufacture gloves having a cut out portion are generally described herein. Other embodiments of gloves may be described and claimed.

An exercise apparatus includes an adjustable frame being attachable to an assistive ambulation device. The adjustable frame includes removable handles, fitting arms located on a lower portion of the adjustable frame to receive a fitness attachment, and attachment points on located on the lower portion of the adjustable frame to couple a resistance device. A jump rope trainer includes a handle; flexible tubing including a handle fastener to connect the handle to the flexible tubing; and a soft sphere shaped object. The flexible tubing includes a soft sphere shaped object fastener to connect the soft sphere shaped object to the flexible tubing.

A sporting good implement, such as a hockey stick or ball bat, includes a main body. The main body may be formed from multiple layers of a structural material, such as a fiber-reinforced composite material. One or more microlattice structures may be positioned between layers of the structural material. One or more microlattice structures may additionally or alternatively be used to form the core of a sporting good implement, such as a hockey-stick blade. The microlattice structures improve the performance, strength, or feel of the sporting good implement.

A baseball or softball bat includes a barrel extending from a handle. A chamber is formed in the bat, such as in the knob attached to the handle, or an end cap attached to the barrel. A liquid or gel at least partially fills the chamber and dissipates vibrations created when the bat strikes an object.

A system and method for monitoring performance of a physical exercise routine. The system comprises a plurality of motion and position sensors configured to generate sensory information including at least a rate of movements of a user performing the physical exercise routine; a database containing routine information representing at least an optimal execution of the physical exercise routine; a training module configured to: compare the generated sensory information to the routine information to detect at least dissimilarities respective thereof, wherein the dissimilarities indicate if the pace of performing the physical exercise routine is incorrect; provide feedback to the user with at least instructions related to correcting the pace of performing the physical exercise routine; and a display for displaying the feedback.
