A sports ball includes sensing electronics embedded therein. The electronics are supported on an inner surface of the wall of the ball within an elastomeric boot that extends inwardly toward the center of the ball. The elastomeric boot is configured to protect the electronics from damage due to shock as the ball is used, and to have little if any effect on the performance characteristics of the ball.

An open field game arrangement includes glowing targets and provides responses, such as lights and sounds, when the targets are hit.

The present specification discloses an exercise system comprising a stable support purchase, such as a ballet barre, and an unstable support apparatus, such as a ball or a roller, wherein an individual may support a limb on the unstable support apparatus and selectively contact the stable support purchase for balance while performing an exercise, such as a ballet position, and an associated method comprising the steps of positioning at least one limb on the unstable support apparatus and simultaneously performing the exercise.

Disclosed is a swimming assistance apparatus, which is worn on a user's both feet to provide the user with buoyancy, such that the user can float on water and swim in a good swimming style while repeatedly moving the waist from side to side like a fish, thereby reinforcing the user's waist muscles. Persons who have knee joint arthralgia or backache or persons who have disability in the lower body can use the swimming assistance apparatus for medical purposes, such as pain relief or treatment.

A balance trainer having a dome and a base formed integrally is provided. Besides, a mold assembly for manufacturing the balance trainer that has a dome mold, a girdle, and a cover is provided. The girdle is sleeved on the dome mold and the cover is fixed on the girdle and thereby a cavity is formed in the mold assembly. Furthermore, a manufacturing process of the balance trainer is also provided. The process has the following steps: preparing ingredients of the dome and the base; feeding the ingredients of the dome into the dome mold; fixing a membrane on the dome mold via the girdle; feeding the ingredients of the base; sealing the ingredients via the cover; and then rotational molding. With the process and the mold, the rotational molding step can mold two materials at the same time, so the product can have two parts with different hardness.

An exercise and therapeutic device includes a treadmill comprising a running belt coupled to a treadmill frame and an offloading system coupled to the treadmill. The offloading system includes an air chamber surrounding the running belt adapted to be selectively inflated between a deflated condition and an inflated, operating condition, a user seal coupled to the air chamber, adapted to receive a user so that, in an operating condition, at least a portion of a user is received in the user seal and positioned within the air chamber and to seal the air chamber around the user, a pump operable to inflate the air chamber, at least one strap coupled to the treadmill frame and adapted to restrict the expansion of the air chamber and adjust a spacing of the user seal relative to a running surface of the running belt when the air chamber is inflated.

A remotely operated blood flow occlusion or restriction cuff for use as a muscle building device or a compact medical emergency reperfusion tourniquet. A module on the cuff housing an air pump, a controller operating the air pump and power supply. The inflation and deflation of the cuff controlled using a smart device in communication with the controller. In the preferred embodiment this is via a Smartphone app and Bluetooth protocol. The tourniquet operating in conjunction with a Doppler ultrasound and/or pulse oximeter to monitor arterial inflow.

Described herein is a golf bag with a collapsible pocket assembly. The golf bag can comprise a first pocket, a second pocket, and a third pocket, wherein the third pocket comprises a wall. The third pocket wall can comprise a first region and a second region, wherein the first region of the third pocket wall is the same wall as at least one of the sidewalls of the second pocket. When shipping golf bags, the golf bag flats oftentimes must be shipped separately from the golf bag tops. The instant golf bag can be collapsed for shipping, allowing the golf bag tops to be partially installed onto the golf bag flats prior to shipping, reducing shipping and assembly labor costs.

A compression device for applying controllable compression to a portion of the anatomy of a user, includes a body, at least one memory wire embedded in the body and configured to contract in length upon application of a current so as to reduce an effective length of the body and apply a compressive force to the portion of the anatomy of the user, and a controller configured to selectively apply current to the memory wires to contract the memory wires and reduce the effective length of the body. The controller includes a circuit board supported by the body and a microcontroller mounted to the circuit board, the microcontroller programmed to actuate the memory wires according to a compression protocol stored in a memory associated with the microcontroller. Each memory wire has a first end fixedly connected to the circuit board and a second end fixed relative to the body.

Disclosed herein are various forms of hybrid baseball bats comprising a wood shell having a radial wall and an outer radial surface profile defining a baseball bat. The wood shell having a central core with a central surface thereon extending from a distal end of the bat. The central surface being profiled with a taper that in some embodiments extends entirely through to the proximal end. A fibrous construct is housed in the central core and infiltrated with an epoxy resin. In some forms, the fibrous construct is in the form of a sleeve. Disclosed are various manufacturing techniques for manufacturing hybrid baseball bats including a low pressure bladder method, a high pressure bladder method, and a centrifugal force method.
