A treadmill has a treadmill frame and a treadmill belt movably mounted on the treadmill frame. An air space exists between the treadmill belt and a support surface on which the treadmill is placed at a rear of the treadmill belt. A disconnect switch is positioned to engage an object entering the air space. The disconnect switch is operatively connected to the treadmill motor so that the treadmill motor automatically shuts off when the disconnect switch is activated.

A treadmill has a front or rear set of pulleys and a looped running belt. The pulleys rotate with the movement of the belt, e.g., when a user walks, jogs, or runs on the treadmill. The pulleys are mounted on a rotating roller tube so that the roller tube rotates with the pulleys. The roller tube is mounted on a stationary shaft using bearings on each side and a one-way device that allows the pulleys to rotate in one direction. The rotation direction corresponds to the movement of the top of the belt from the front to the rear of the treadmill. The one-way device prevents the pulleys from rotating in the opposite direction, preventing the top of the belt from moving from the rear of the treadmill to the front. The one-way device may be a sprag clutch. The treadmill may be a motor-less, curved treadmill.

A configurable golfing apparatus including a rectangular handle portion. The rectangular handle portion includes a golf club shaft that is securely mounted within the configurable golf club handle. The rectangular shape provides new and additional hand placement and new and additional configuration capabilities for both right handed and left handed golfers. The configurable golfing apparatus allows different golf club heads (e.g., drivers, irons, putters, etc.) to be inserted and removed from the configurable golfing apparatus. The golf club shaft inside the rectangular handle portions complies with straightness, bending and flexibility, and twisting and torque, properties and attachment to a golf club head requirements for a golf club shaft required by the United States Golf Association (USGA) and Royal and Ancient (R&A) Golf Club of St Andrews rules and functions in a manner similar to a golf club shaft not enclosed in a rectangular handle portion.

Measuring device / sensor system for measuring, transferring and processing of relevant performance data from training and competition in contact sports, in particular the physical contact and its force effect

In practice and as far as possible, performance data in contact sports, in particular those of factual contact and force effect of relevant objects and persons to each other, are not surveyed separately but evaluated subjectively. In contact sports like martial arts this is especially critical, because an occurred contact and its force effect are the significant success data in these sports. In other types of contact sports, e.g. ball sports one is concentrated on the performance data, that lead to goal achievement (e.g. goal scoring) and is not looking objectively into the performance of participants for, for example, draw conclusions about the correct technique execution at any time in a game or competition. Though there are already measuring devices for some contact sports for detecting force effect and contact, these are limited to several defined single sensors and applications. Therefore it may be possible to make objective measurement but in case of doubt, a subjective evaluation of technique and point assignment is still necessary. This invention contains a system of measuring devices, that can, especially in martial arts sports, improve the point assignment and in other contact sports the evaluation of techniques. These special measuring devices for contact measuring and its movement and acceleration sensors, display systems and hardware interfaces can be combined with software interfaces and be tailored to fit different applications. In case of martial arts sports, the configuration of protective equipment with these measuring devices is one use case, in which the measuring devices detect all relevant data like contact, force effect and movement direction, that can be used for competition decisions.

This invention is embodied by a controlled, variable tension line, payout reel machine. A system of sensors detect line tension and line distance paid out, location, and transmit through wired and unwired communication to a microprocessor. The microprocessor is co-located with the reel structure, which in turn applies, via a brake feature, resistance to the reel which is paying out the line being pulled by the user. This invention pertains to all applications where it is desirable to control the tension in a line paid out from a reel or reel. As stated, the payout motive force is supplied by the person, animal or apparatus attached to the end of the line, opposite the reel. The invention applies to the field of precise and measured control of line tension for sport, sport training, performance testing.

A system for a manual treadmill having a tread that rotates around a front axle and a rear axle and side rails on opposing sides of the tread includes a brake configured to slow rotation of at least one of the front axle or the rear axle, a controller, and a first presence sensor in communication with the controller, the first presence sensor positioned on a side rail and configured to detect a user on the side rail. The brake is not normally engaged during operation of the treadmill when the tread is moving and the first presence sensor does not detect the user on the side rail. The controller is configured to, in response to the first presence sensor subsequently detecting the user on the side rail, engage the brake.

An Internet of Thing (IoT) sport device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

An integrated multi-purpose hockey skatemill with a movable skatemill belt (2) comprising a stationary area of the artificial ice (1) with a front face of the work area wherein a movable skatemill belt (2) is built in by means of barrier-free transition areas with a system of spaced signalization/display elements (5) hung on the tiltable/sliding brackets (5a) at the frontal and lateral sectors with respect to the center of the movable skatemill belt (2). There is a safety restraint system (3) and a stabilization system (4) anchored above the movable skatemill belt (2). A tensile/compressive force measuring system (8) is suspended from above in the longitudinal axis of the movable skatemill belt (2). The said skatemill comprises an electronic control unit (9) ECU controlling the operation of the movable skatemill belt's (2) drive system, the system of signalization/display elements (5), the system of optical scanning cameras (6) and the tensile/compressive force measuring system (8). There are two puck feeders (7) located on the border line defining the front side of the work area. There is a hockey goal structure with target zones impact detection sensors located on the edge of the work force in front of the movable skatemill belt (2). Two laser markers (12) used to define the width of a skate track may be located on the stationary area of the artificial ice in front of the movable skatemill belt.

Disclosed are biofeedback methods and devices suitable for providing biofeedback useful for helping a user control an own breathing, for example, to help in inducing deep breathing, and such biofeedback devices further comprising a dispenser for dispensing an inhalable substance.

A force measurement mechanism comprises two force input members (105, 106), a pair of cantilever springs (101, 102), and a force measuring means (107). One portion of each cantilever spring is held by a first constraint means (103) and one portion of each cantilever spring is held by a second constraint means (104) with each cantilever spring having an unconstrained length between the first and second constraint means that is free to bend. The constraint means (103, 104) hold the cantilever springs (101, 102) in a parallel and spaced apart arrangement. The force input members (105, 106) are attached via the constraint means so that relative movement of the force input members bends the cantilever springs (101, 02), and the force measuring means (107) is arranged to measure force applied between the force input members.
