The system is comprised of a display device and sensors having strain gauges attached to a weight lifting bar. The system will determine and display the actual weight lifted by a user with or without a spotting force, and a spotting force applied.

A Vertical Running Machine called a VARRI—Vertical, Anti-Gravity, Re-habilitation, Recovery, and Impact Resistant. It relates to the field of bio-mechanical technology, human physiological facts, and the relationship of gravity and the functionality of the body in motion. This is a Vertical, Anti-gravity device created for Recovery from injuries, physical therapy Rehabilitation with the functional characteristics of Impact-free conditioning and by providing a non-impact system to improve the conditioning or recovery of the user, the patient or the elderly. The device provides a method of a more rapid and safer recovery from injuries and surgery and also is capable to provide enhanced athletic performance by using a vertical, non-impact system which alleviates the damages on the muscles and skeletal structure of the body from the continuous impact of horizontal running on the ground.

Controlling access to a stationary exercise machine. In one aspect of the disclosure, a method may include establishing one or more authorized users of a stationary exercise machine having one or more moveable members, automatically locking the one or more moveable members of the stationary exercise machine, and receiving a request to perform a workout on the stationary exercise machine. In response to the receiving of the request to perform the workout on the stationary exercise machine, the method may include automatically determining whether any of the one or more authorized users is proximate to the stationary exercise machine. In response to automatically determining that one of the one or more authorized users is proximate to the stationary exercise machine, the method may include automatically unlocking the one or more moveable members of the stationary exercise machine to enable the workout to be performed on the stationary exercise machine.

A method includes providing a first video file to a plurality of exercise machines, the first video file including content associated with an exercise class. The method also includes receiving user data from the plurality of exercise machines, the user data including respective settings associated with a common performance metric. In such a method, the respective settings are used on the plurality of exercise machines during playback of a particular part of the first video file. The method also includes identifying a timestamp associated with the particular part of the first video file, and generating an executable control corresponding to the performance metric. The method further includes generating a second video file comprising the content and the executable control. In such methods, playback of the second video file causes display of the executable control at a part of the second video file corresponding to the timestamp.

A system for measuring vertical jump is disclosed, in accordance with one or more embodiments of the present disclosure. The system may include a vane assembly comprising a plurality of vanes movably coupled to an extendable member at a plurality of heights relative to a ground level, each being vane displaceable from an original position to a displaced position in response to contact from a user. The system may also include a measurement device configured to obtain at least one of: a baseline height from a first vane of the plurality of vanes to the ground level; a user height; a user reach; or a displacement height, wherein the displacement height is the height of the uppermost vane in a displaced position relative to the ground level. The system may also include a controller communicatively coupled to the measurement device.

A rehabilitation feedback system is used during rehabilitation of one or more body appendages of a user. The system includes four finger tracking elements and a thumb tracking element supported for movement relative to one another so as to allow a user to performs a gripping motion when the elements are coupled to the fingers and thumb of a user. A biasing member provides a resistance force acting to urge each tracking element towards a starting position thereof. A visual barrier is adapted to hide the hand of the user at a first side of the visual barrier from direct visual sight by the user at a second side of the visual barrier. A sensor at the first side of the visual barrier detects movements of the tracking elements and communicates with an indicator element detectable by the user from a second side of the visual barrier.

A method for calculating distance information according to the present invention includes: acquiring a current location; reading out map information of a golf course corresponding to the current location; calculating a horizontal distance to a target of the golf course from the current location by using the map information; calculating two first direction intersection where a straight line in a first direction, connecting the current location and the target, and a green boundary line of the golf course meet; calculating two second direction intersection where a straight line, which is perpendicular to the first direction and passes through the target, and the green boundary line meet; and calculating edge distances between the target and the two first direction intersection and between the target and the two second direction intersection.

The present invention relates to selectively adjustable speed and incline levels for treadmills. An example treadmill includes a platform around which a belt rotates, a drive motor for controlling a speed of rotation of the belt, a linear motor for controlling an incline of the platform, a human machine interface configured to receive from a user a first selection regarding at least one of the speed of rotation of the belt and the incline of the platform, at least one manual lever configured to receive from the user a second selection to respectively refine the first selection, and at least one controller that selectively changes the speed of rotation of the belt or the incline of the platform based on the first selection received by the human machine interface, and selectively and respectively refines the first selection based on the second selection received by the at least one manual lever.

A putter head having an upward-facing surface portion and a diffusely reflecting area of at least 5% of a total upward-facing area, which is also has a low gloss value and preferential CIELab L* value, an alignment feature delineating a transition between a first portion of the upward-facing surface having an area of contrasting shade or color with a shade or color of a portion of the face adjacent the upward-facing surface, and a face with at least a portion adjacent the upward-facing surface having a diffusely reflecting face surface area with a low gloss value and preferential chroma value. The alignment feature may have a preferential contrasting color difference between the first portion of the upward-facing surface and a portion of the face, and preferential CIELab ΔL difference value between a portion of the face and the diffusely reflecting surface of the upward-facing surface.
