A system for a treadmill with a tread that rotates on front wheels supported on a front axle and rear wheels supported on a rear axle includes a locking mechanism. The locking mechanism comprises a first device associated with one of the front axle or the rear axle and configured to prevent rotation of respective front wheels or rear wheels in a first direction and a second device associated with another of the front axle or the rear axle and configured to prevent rotation of the respective front wheels or rear wheels in a second direction opposite the first direction. The system also includes a controller and a sensor configured to detect a user on the tread. The controller is configured to, in response to the sensor detecting no user on the manual treadmill, engage the locking mechanism to prevent movement of the front wheels and the rear wheels.

An electromechanical device for rehabilitation includes pedals coupled to radially-adjustable couplings, an electric motor coupled to the pedals via the radially-adjustable couplings, and a control system including a processing device operatively coupled to the electric motor. The processing device configured to, responsive to a first trigger condition occurring, control the electric motor to operate in a passive mode by independently driving the radially-adjustable couplings rotationally coupled to the pedals. The processing device also configured to, responsive to a second trigger condition occurring, control the electric motor to operate in an active-assisted mode by measuring revolutions per minute of the radially-adjustable couplings, and cause the electric motor to drive the radially-adjustable couplings when the measured revolutions per minute satisfy a threshold condition, and responsive to a third trigger condition occurring, control the electric motor to operate in a resistive mode by providing resistance to rotation of the radially-adjustable couplings.

A method for ball game training, the method comprising steps executed by at least one computer, the steps comprising: receiving image data of a player and a ball, the image data being captured using at least two cameras, using the received image data, tracking motion of the player and motion of the ball in three dimensions, based on the tracked motions, predicting a position of the player and a trajectory of the ball, and based on the predicted position and trajectory, generating a control command for at least one ball throwing machine.

A preloaded resistance pack and exercise device. The resistance pack includes an elastomeric resistance element coupled to a hub and disposed on a plate. The hub includes a pair of radially extending wings that lie against a surface of the plate. The plate includes a pair of raised tabs that lie within a rotational path of the wings. An initial rotation of the hub relative to the plate causes the wings to slide over and beyond the raised tabs and at least partially stretches the resistance element. Interaction between the tabs and wings prevents the hub from rotating back to an initial position and maintains the resistance element in a preloaded, tensioned condition. The exercise device is configured to detect a number of the resistance packs coupled thereto as well as data associated with exercise movements employing the resistance packs.

The present invention is a ball feeding and throwing apparatus that is capable of feeding multiple ball throwing devices. The present invention feeds balls to each device at a constant rate and allows each ball feed to be independently controlled via a remote control. The present invention comprises a main hull, feeder modules, feeding tubes, and ball throwing devices. The main hull be an all-in-one system which feeds balls via the feeder modules at a constant rate. The feeder modules then transfer the balls through the feeding tubes to each of the multiple ball throwing devices where the balls are thrown towards an athlete.

The present invention allows a single coach to control a number of ball feeds remotely and independently. Thereby allowing a single coach to train a number of athletes at one time. Further, the training experience is improved as the coach is free to control the ball feeds remotely, placing the coach in close proximity to an athlete. The close proximity allowing improved communication, greater observation, and allows for hands on training and demonstration.

A kit comprising at least 2 devices adapted to be easily attached by way of suction to one or more sides or a bottom of a swimming pool, each of the devices having a grab member adapted to be grabbed by a hand of a child player or an adult player, the devices adapted to be easily attached to a side or bottom of the pool. A game can be played with the devices after they are attached at separate points such that a player may grab a first device with one hand and then a second device with another hand, moving along said side or said bottom while remaining under water. The device comprises a housing having an upper grab member having a height, diameter, cross-section, shape, and surface configured to be grabbed by a hand of a child or an adult, an actuator member configured to move up and down within the upper grab member, a spring member within the upper grab member arranged and adapted to urge the actuator member in an upward direction, and a flexible disk shaped member adapted to engage a swimming pool side or bottom by suction. The device is waterproof and is designed to be engaged by suction by pressing a release button while the flexible disk shaped member is pressed against an underwater pool surface

In an aspect, an apparatus is provided and includes an air-tight object having an outer layer, an inner layer, and a cover, and a light module. The opacity of the outer layer is greater than the opacity of the inner layer. The outer layer defines a first aperture and a second aperture. The inner layer and the cover define a first interior region. The inner layer defines a second interior region. The light module is encapsulated within the first interior region and is configured to send light through the inner layer, through the second interior region of the air-tight object, and through the second aperture of the outer layer, wherein the cover is disposed between the light module and the outer layer.

An illuminated cornhole platform comprising a top portion, at least two side portions, a front portion, a hole portion, at least one leg portion, and a back portion. The cornhole platform is illuminated by illumination sources arranged along a majority of an outer perimeter of the rectangular platform, with the plurality of illumination sources outlining the outer perimeter of the rectangular platform.

This disclosure relates to using a hand held target (e.g. tae kwon do paddle) as a tool for providing physical performance instructions according to a digital workout performance template loaded in advance.

A light-emitting golf ball using a small generator includes a core that is a center point of the golf ball; an inner shell formed to surround the core; an outer shell formed to surround an outer surface of the inner shell and struck by a golf club; a generator positioned on one side of the inner shell and generating a current based on a rotational force caused by a stroke; and a light emitting portion located on one side of the inner shell and providing light so that the golf ball emits light based on the generated current. According to the present disclosure, the golf ball emits light, and thus it is easy to track a trajectory of the golf ball. In addition, it is possible to more easily determine the trajectory and position of the golf ball when the day is cloudy or enters the night.
