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

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.

Innovative apparatuses and methods for a novel training device is provided that includes a base, a frame, a material attached to the frame, wherein the material comprises a non-solid material; and an image affixed to a first side of the non-solid material, wherein the image is viewable on the first side of the non-solid material and viewable on a second side of the non-solid material.

A protective liner, attachable to the inner surface of a helmet, comprising an inner face and an outer face oriented towards the inner surface of the helmet, wherein the joining of faces gives rise to a plurality of inflatable chambers permeable to water vapour and connected by means of pressurised air distribution channels. The chambers and channels form a single body extending at least along the inner surface of the helmet above the Frankfurt plane. The outer face comprises a layer of rigid material while the inner face comprises a layer of elastic material, whose area expands when the chambers are filled with air, such that the expansion in volume occurs mainly by means of the deformation of the elastic layer.

A wearable massage and/or compression device for applying controllable scrolling or intermittent sequential forces, such as compression forces, to the body and limbs of a user comprises one or more shape-memory wires integrated into an article of clothing and configured to apply a compression pressure to the limb through the fabric body upon changing shape in response to a stimulus, a pre-tensioning apparatus in the form of a bungee cord associated with each shape memory wire, and a micro-processor based controller for selectively actuating the one or more shape memory wire to reduce the length of the shape memory wire to thereby apply pressure to the wearer's body.

An exercise device and an inflatable alternative are provided. The exercise device is composed of a planar base attached to block(s). The block(s) may serve as cushioning or weighted items to enable a variety of exercises. The planar base is securable against a structure such as a door frame. The planar base is also convertible to a bench with shaft(s) that connect block(s) to form legs for the bench. The inflatable alternative includes a top end that is securable to the structure. A bottom end of the inflatable alternative is securable to a user through an ankle cuff. The ankle cuff provides the user a measure of control over a mobility of the inflatable alternative during an exercise.

A training ball includes a resilient shell having an outer surface and an inner surface defining an interior chamber therein. Weighted filler material is disposed within the chamber. A valve stem extends radially inwardly from the shell inner surface and into the interior chamber. An opening along the valve stem extending from the interior chamber to the outer surface of the shell, with a valve disposed in the opening. A transition between the valve stem and an inner surface of the outer shell is curved, tapered, or otherwise graduated to reduce stress at the transition such that a widest portion of the transition is at least twice as wide as a narrowest portion of the valve stem. The transition can be curved with a fillet radius of between about 5-15% of the outer diameter of the ball, and/or between about 4-10 mm.

A neck gaiter system configured to be received on the neck of a wearer that includes a gaiter member that includes a neck portion and a clavicle portion, a sensor system that includes at least one gyro sensor positioned on the gaiter member, an actuation system in electrical communication with the sensor system, and a bladder positioned on at least the neck portion of the gaiter member. The bladder is in fluid communication with the actuation system. When the sensor system senses a predetermined rotational change, the actuation system inflates the bladder.

An exercise device includes a resilient compression member configured to resist a compressive force from a user, and a resilient tension member configured to couple to opposing sides of the compression member. The resilient tension member is also configured to form a first portion of a loop around the compression member and the user, and resist a tensile force from the user. The exercise device also includes an extension member configured to connect with opposing ends of the tension member to form a second portion of the loop around the compression member and the user.

A swim lane apparatus having one or more attachment or tethering devices. The one or more attachment or tethering devices are configured to couple or affix to a foundation of the pool. The swim lane apparatus has a first sidewall. The first sidewall is coupled to the one or more attachment or tethering devices. The first sidewall is configured to form a channel and direct a flow of water out of the channel when the flow of water enters the channel.
