A device, sometimes mobile, which simulates human motion, such as an omnidirectional sensing target. The target that can detect and differentiate between projectile (bullet) hits to the head, body, and one or more peripheral regions (e.g., arms, pelvis, legs) of a humanoid-form target, elicit a physical response from the mobile device based upon the sensing data, and provide real time feedback to a user (shooter) via a user-friendly interface. The target includes multiple layers of conductive material separated by one or more insulating layers. Forming can be by wrapping planar sensing panel into a three-dimensional configuration such that the panel occludes a three-dimensional volume and presents surfaces sensing projectiles from all directions. Associated circuitry is configured to have a bullet pass through multiple zones and to electronically detect the bullet path based on a combination and/or sequence of zones detecting bullet passage.

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

A knee rehabilitation system includes a plurality of compressible resistance members, a knee garment, and a resistance member receptacle. Each compressible resistance member in the plurality of compressible resistance members has (i) a same size and a shape as each other compressible resistance member in the plurality of compressible resistance members, and (ii) a compression resistance different from each other compressible resistance member in the plurality of compressible resistance members. The knee garment has a knee garment ventral portion and a knee garment dorsal portion. The resistance member receptacle is coupled to the knee garment dorsal portion, and the resistance member receptacle is sized to carry each compressible resistance member in the plurality of compressible resistance members, one at a time.

The present invention is a portable resistance machine that allows a user to perform rowing, skiing, paddling, or any other physical activities at any suitable location. The portable resistance machine contains a housing, a pulley, a flywheel, a planetary gear assembly, an anchor, a retraction mechanism, and a pull cord. The housing contains a central gear support. The pulley, the flywheel, the planetary gear assembly, and the retraction mechanism are positioned within the housing. The central gear support is positioned within the housing. The planetary gear assembly is positioned within the central gear support. The pulley and the flywheel are axially connected opposite to each other along the planetary gear assembly. The retraction mechanism is operatively connected to the pulley, where the retraction mechanism is configured to retract the pull cord into a spooled state around the pulley. The anchor is externally connected to the housing.

An exercise device having a unique asymmetrical shape with rounded ends of differing radii to provide stability and added resistance.

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.

Inflatable toys and related methods are generally described. In some embodiments, an inflatable toy may be multifunctional, allowing a user to use the toy for multiple activities or games. In some embodiments, the toy may include a removable body, which may be removed from the toy to allow the user to switch between various games. In some embodiments, the removable body may include one or more projections which may receive one or more rings for a game of ring toss. In some embodiments, the toy may include a depression in which it may receive one or more projectiles for a game of cornhole. The inflatable toy may be used while floating on water or placed on solid land.

Inflatable toys and related methods are generally described. In some embodiments, an inflatable toy may be multifunctional, allowing a user to use the toy for multiple activities. In some embodiments, the toy may be used to play a game, such as ring toss, and may also have an added functionality of fluid sprinkling. In some embodiments, the toy's functionalities may be used in parallel or separately. In some embodiments, the toy may include one or more projections which may receive one or more rings. In some embodiments, the toy may include a nozzle which may be configured to expel pressurized fluid (e.g., water) to cool the surrounding environment.

AirBags are constructed out of heavy-duty “dropstitch” material to the same size and specifications as competitive cornhole boards. They are inflatable in design which will allow them to be quickly and easily inflated/deflated and rolled up into a backpack type of carrying case. This makes for easy and efficient transport. In order to appropriately position the board, two heavy duty rubber “legs” are screwed into the board for elevation and stability of the playing surface.

An American-style football may include a prolate spheroidal shaped bladder having a longitudinal axis, an outermost layer about the bladder, a lacing surface featuring a series of parallel projections from an exterior of the outermost layer and an intermediate sandwiched between the bladder and the outermost layer, wherein the intermediate layer is configured to decrease a MOI of the football.
