Disclosed are implementations of a sensor enabled exercise slider configured to detect movement and applied force. A sensor enabled exercise slider is a limb-actuated, linearly and circularly moveable, apparatus configured to facilitate a variety of exercises. An example limb-actuated exercise slider comprises: a housing that is smoothly slidable across a contacted surface in contact with an undersurface of the housing; and an electronic circuit carried by the housing. The electronic circuit is configured to detect movement of the housing and to detect force applied to a top surface of the housing. In some implementations, the undersurface in contact with the contacted surface has a friction coefficient permitting the sliding.

A walking training system according to the present embodiment includes: a treadmill; a load distribution sensor that is provided on a lower side of a belt of the treadmill so as not to move together with the belt and that detects a distribution of a load received from a sole of a trainee riding on the belt of the treadmill; an extraction unit that extracts a load distribution in a region corresponding to a position of the sole of the trainee during walking training, out of a load distribution detected by the load distribution sensor; and a determination unit that determines a walking state of the trainee based on the load distribution extracted by the extraction unit.

A tensile strength training device having a handheld housing with a curved electronic display panel defining a housing channel and with a left side panel and a right side panel each flanking and coupled to the curved electronic display panel, each with a sidewall defining a concave cavity, two opposing handle apertures, and two opposing bracket apertures. Left and right U-shaped handle brackets are disposed within the respective wo opposing bracket apertures and coupled to a handle member disposed within the concave cavity thereon for grasping by a user and disposed within the two opposing handle apertures. The device includes a printed circuit board electrically coupled to a power source, a force sensor operably coupled to the left and right U-shaped handle brackets, and operably configured to measure a tensile force applied thereto that is able to be displayed around at least 180° of the curved electronic display panel.

Apparatus and methods for providing breath training. In illustrative embodiments, an operator creates a pressure, either positive or negative, in the lungs. This pressure is transferred through a mask assembly to a breathwork apparatus, which utilizes pistons moving within cylinder volumes to provide numerical feedback to an operator regarding the operator's breathing. Through breath control exercises, the operator of a breathwork apparatus can develop deeper and slower breathing habits which are more efficient. One embodiment provides a breathwork apparatus comprising an exhalation side; a transfer case; an inhalation side; and, a mask assembly, wherein the exhalation side and inhalation side are joined by transfer case which comprises a plurality of channels, such that at least a first channel of a plurality of channels terminates in an exhalation rate meter, and at least a second channel of the plurality of channels terminates in an inhalation rate meter.

A mobile device associated with a user and a smart fitness equipment unit are provided, where the mobile device is a central device and the smart fitness equipment unit is a peripheral device in communication with the mobile device.

An item of sports equipment includes a guy line to which is applied a mechanical tension and which ensures the stability or the rigidity of the item of sports equipment. The sports equipment includes a measuring apparatus which is fastened to the guy line such that the guy line tension is applied to it, the measuring apparatus including a sensor adapted to deliver an electrical signal corresponding to representational information on the guy line tension. The measuring apparatus is fastened to the guy line all the time, making it possible to obtain representational information on the guy line tension at any instant.

A method for manufacturing a golf ball. The method includes creating a core with a cavity therein and positioning electronics in the cavity. The method further includes filing the cavity with a fill material while the electronics are positioned in the cavity such that the core, the electronics, and the fill material together form a spherical body, and such that when the fill material is cured the spherical body is balanced about a center thereof. The method further includes curing the fill material and covering the spherical body with an exterior cover.

The present invention may be embodied as a system or method for dynamically exercising a user's neck muscles. The system includes a headset, an arm attached thereto, a weight, and at least one motor to move the weight, for example, about the arm. The weight may be mounted eccentrically on a radial track that is rotatable by one motor and moved linearly by another motor. The direction of the arm, the distance between an apex of the headset and the weight, the eccentricity of the weight on the axis, and the speed of rotation of the motor are all parameters that can be adjusted by the caregiver or user, either manually or via controlling software.

A smart ball-machine uses artificial intelligence to train a player or to play with a player. For example, the ball-machine can adjust the tennis ball speed, topspin, bounce according to the player's successful ball return rate. The ball-machine can be preconfigured with a profile of a player. For example, the ball-machine may download a complete profile of a tennis player from a game recording, or may download a file with a customized profile of a player to train a player using the ball-machine. The ball-machine is equipped with a plurality of wheels, motors, and shafts to provide a fully customizable launch of one or more balls. For example, the ball can be launched from the machine from one side of a tennis court to another side of a tennis court with a variety of speeds, trajectories, topspin, bounce etc.

Electromechanical rehabilitation of a user can include receiving a pedal force value from a pedal sensor of a pedal; receiving a pedal rotational position; based on the pedal rotational position over a period of time, calculating a pedal velocity; and based at least upon the pedal force value, a set pedal resistance value, and the pedal velocity, outputting one or more control signals causing an electric motor to provide a driving force to control simulated rotational inertia applied to the pedal.
