A treadmill with a safety monitoring function includes a running unit and a detection unit. The running unit includes a driving roller and a running belt for a runner to stand and run thereon. The detection unit includes a sensor for detecting whether the runner exists at a predefined height on the running belt. The detection unit can be moved to change the predefined height. A safety monitoring function for a treadmill includes adjusting a height of the sensor, detecting whether the runner exists at the predefined height above the running belt, and generating a first monitoring output. Through detecting whether the runner exists at the predefined height, it determines whether the driving roller can be driven by the driving unit to prevent accidental activation by a child. Since the detection unit can be moved to change the predefined height, it allows the use by runners of different body shapes.

A treadmill with a safety warning function includes a miming unit, a driving unit, a detection unit and a control unit. The running unit includes a driving roller and a running belt provided for a runner to stand thereon. The detection unit includes a camera arranged at a predefined height range on top of the running belt for photographing images. The control unit determines a height of the runner based on the images photographed. The safety monitoring method for the treadmill includes obtaining an image above the running belt and determining whether the height of the runner is greater than the predefined height. By determining whether the height of the runner is greater than the predefined height, it is able to determine whether the driving roller can be driven by the driving unit to rotate, thereby preventing the hazard of accidental activation by a child of insufficient height.

A treadmill may include a deck, a first pulley incorporated into the deck, a second pulley incorporated into the deck, a tread belt surrounding the first pulley and the second pulley, a motor in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction, and a runaway mitigation mechanism in at least indirect mechanical communication with the motor. The runaway mitigation mechanism at least mitigates a motor runaway condition.

This disclosure relates to a relatively compact smart ball launching system and associated methods for using the same. In various embodiments, the disclosed ball launching system may comprise a collapsible ball hopper that can store a larger number of balls while maintaining a relatively compact size. In certain embodiments, brushless motors may be used to improve power efficiency while allowing for accurate launch speeds and/or spins. In some embodiments, a pre-launch chamber may be included in a ball dispensing mechanism that may facilitate on-demand shots and/or power savings by shutting the ball launching system down when the ball hopper is empty. In further embodiments, the ball launching system may be controlled, at least in part, via a mobile device. In some implementations, the ball launching system may include and/or otherwise interface with a camera system to facilitate improved calibration and/or record user actions.

A digital slope meter includes: a shaft extended in a longitudinal direction thereof and having a rolling groove formed on top thereof in the longitudinal direction thereof to allow a golf ball placed thereon to be moved down therealong, when the rear side thereof is tilted up in a state where the front side there is located on a green, and to then roll on the green from a discharging end formed at the front end thereof; and a measuring module located on the shaft to measure a moving distance and an isolated angle of the golf ball rolling on the green from the discharging end when the rear side of the shaft is tilted up.

A direct-drive bicycle training system and methods of using the same are provided. The system includes a bicycle trainer that rests on a support surface and supports a bicycle frame in an upright manner with respect to the support surface. The bicycle trainer includes a stator, a rotor that rotates with respect to the stator, a cassette affixed to the rotor, a support frame supporting the stator, rotor, and cassette, and a resistance applying mechanism that operatively couples to a portion of a drivetrain of the bicycle frame and applies varying levels of resistance to the portion of the drivetrain. The support frame moves with respect to the support surface in response to a force applied to the drivetrain of the bicycle frame during use of the bicycle training system, generating a more natural movement of the bicycle and simulating on-road use.

A treadmill according to the present invention includes: a frame; an endless belt; an endless-belt drive unit; a plurality of cameras provided on the frame such that the orientations and/or locations thereof can be adjusted; a motion-data acquisition unit that markerlessly acquires motion data of a subject by using image information obtained with camera images; a motion analysis unit that analyzes the motion of the subject by using the motion data; and a control unit that controls the endless-belt drive unit based on the motion data.

A haptic simulation exercise device includes a frame, a contact point supported by the frame, and an actuator. The contact point is configured to allow user contact with the exercise device during use of the exercise device. The actuator is configured to displace the contact point relative to the frame.

A walking support system is a walking support system which supports walking of a user, and includes a display unit, a landing timing detection unit configured to detect landing at the time of walking of the user, a target landing timing setting unit configured to set a target landing timing of the user on the basis of an output of the landing timing detection unit, and a display control unit configured to cause the display unit to display an auxiliary image prompting the user to land at the target landing timing.

A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive a physiological measure. The processor is further configured to display, via the display system, the physiological measure, wherein the display system is disposed in the eyewear so that the physiological measure is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle α from a forward direction.
