A rock climbing wall includes a support wall and a plurality of rock climbing holds attached to the support wall. The rock climbing wall also includes a sensing apparatus that determines that a climber traversing the rock climbing wall has contacted a first one of the plurality of rock climbing holds. In addition, the rock climbing wall includes a control device that, upon receipt of a signal from the sensing apparatus indicative of the climber contacting the first one of the plurality of rock climbing holds, causes at least a second one of the plurality of rock climbing holds to be indicated as an additional hold to be contacted as the climber traverses a climbing route along the wall.

A reciprocating unidirectional electromagnetic resistance device includes a shaft having a flywheel installed to a first end of the shaft, an electromagnetic braking unit, and a first sensing device. A spring return device and a second sensing device are installed at a second end of the shaft, and a pull rope device is installed at the middle of the shaft. The electromagnetic braking unit and the spring return device are integrated into a single module and provided for an operator to perform a reciprocating motion to pull out a pull rope of the pull rope device and drive the shaft, the flywheel and the spring return device synchronously, and the electromagnetic braking unit acts an electromagnetic resistance onto the flywheel, so that the flywheel has the excellent precise resistance of the electromagnetic braking unit. When released, the pull rope can be retracted to achieve the reciprocating motion effect.

A treadmill with an anti-entrapment function allows a user to stand on the treadmill and includes a running unit, a control unit, and a sensing unit. The running unit includes two lateral bases, a driving roller, a driven roller, and a running belt. Each lateral base has a bottom end portion. The sensing unit includes a guard bar pivotally provided at the bottom end portions and at least one sensing member. When the user is accidentally pulled into the gap between the running belt and one of the lateral bases, the guard bar will be subjected to an external force and thus rotated downward about a rotation axis, thereby driving the at least one sensing member to send a warning signal to the control unit, in order for the control unit to control the rotation speed of the driving roller accordingly, lest the user be pulled deeper into the gap.

Treadmill protective cover and methods of use are disclosed herein. An example system includes a protective cover for a treadmill, a sensor associated with the treadmill or the protective cover, the sensor detecting when an object is near or within an entrapping area between the protective cover and a conveyor of the treadmill, and a controller configured to receive signals from the sensor, the controller allowing the conveyor to freely operate when no objects are sensed within the entrapping area and stopping the conveyor when an object is sensed within the entrapping area.

A treadmill with an anti-entrapment function allows a user to stand on the treadmill and includes a running unit, a control unit, and a detection unit. The running unit includes two lateral bases, a driving roller, a driven roller, and a running belt. Each lateral base has a bottom end portion lower than the running belt. The detection unit includes a transmitter for emitting a light wave and a receiver for receiving the light wave. When accidently pulled into the gap between the running belt and one of the lateral bases, the user or a foreign object is moved by the running belt to the space between the transmitter and the receiver, thus keeping the receiver from receiving the light wave. The receiver sends out a warning signal in response, in order for the control unit to control the rotation speed of the driving roller accordingly to prevent continued entrapment.

Embodiments of the present invention are directed to devices, systems, and methods for implementing drills and providing coaching instructions to users. Embodiments may load a drill, measure values obtained from one or more sensors installed on a player's tennis racket and/or worn on the player's body, and use those values to detect various parameters, such as the physical impact of a ball at the player's racket. Embodiments may then output a coaching instruction to the user. Embodiments may also include adding customized coaching instructions to a drill.

A device, method and system improve the breathable air quality of the environment in the region of a specific part of a body, such as around the mouth and nose area of a person buried in an avalanche. The device includes at least one inlet, at least one pump, at least one power resource, a controller, and at least one outlet. An inlet of the pump is constructed to act as a chamber. A first end of the chamber is connected to the inlet and a second end of the chamber is an opening towards the outside of the device. When the pump is activated, the pump will provide a vacuum in the chamber and suck air from the surroundings into the pump through the second end of the chamber and the chamber.

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.

The present embodiments provide systems and methods for aggregating measurements captured by different technologies during a golf swing. By capturing measurements using different technologies, more accurate measurements may be provided to a user by selecting from the measurements, offsetting measurements based on the technologies used, and aligning measurements between devices. Further, by aggregating measurements received from different devices, additional features and functionality may be provided to the user that is absent from any one device used alone. Additionally, by storing the aggregated measurements, users, club fitters and instructors may access and leverage larger databases of measurements to better understand the user's golf swing and to provide better recommendations and instruction to the user.

A handheld exercise device is an apparatus that enables the user to exercise the upper body due to the load applied on the user's arms from the centripetal force created by moving the apparatus using one or two hands. To do so, the apparatus may include an O-ring housing, a crossbar, a bearing assembly, and a control system. The O-ring housing is designed to retain the bearing assembly in such a way that the user can move the bearing assembly in a circular motion within the O-ring housing. The crossbar facilitates the handling of the O-ring housing with one or two hands in order for the user to move the bearing assembly in a circular motion within the O-ring housing. The control system helps the user keep track of the movement of the bearing assembly so that the user can measure the exercise progress while handling the apparatus.
