Abstract: A training device includes a force receiving component, a location detector, a resistance generator, and a controller. The force receiving component moves along a closed trajectory. The location detector is configured to detect a location of the force receiving component in the closed trajectory and to output a location signal. The resistance generator is configured to exert a resistance on the force receiving component. The controller controls the resistance generator to adjust the resistance based on the location signal.

Abstract: A free weight training protection device includes a rack, two transmission modules, a control module and a barbell. The rack includes hanger structures which are configured to be laterally symmetrical to each other. The two transmission modules are configured to be laterally symmetrical to each other. Each transmission module includes a motor, sprockets, chains, pulleys and ropes. When a controller executes a fitness program, the controller operates the motor, so that the rope maintains a basic tension which is a very small tension and will not affect the hand feel of heavy training. If the barbell has an abnormal position or displacement, the controller will start a protection program to prevent the barbell from falling and move the barbell upward, so as to provide protections to users.

Abstract: A treadmill includes sensors on a console at the front of the treadmill. The sensors sense the lateral position of a user relative to the edge of the exercise deck and/or the exercise belt. If the user is close to the edge of the exercise deck, then an alert is displayed on the console.

Abstract: A protective cover and system for detecting objects within or near an entrapment area on a treadmill or devices that incorporate a conveyor belt. A controller enables the treadmill to operate normally when no objects are detected within or near an entrapment area and is designed to stop the conveyor when an object is detected within or near the entrapment area.

Abstract: A weightlifting machine includes a frame assembly having a plurality of pulleys that are connected to a user grip and plurality of weighted panels. A plurality of proximity sensors are positioned along the frame assembly and function to identify a specific number of weighed panels being lifted during an exercise routine. A location sensor is provided along the frame assembly and functions to identify the speed and distance at which the weighted panels move. A system controller is communicatively linked to each of the sensors, and a motor is connected to the cable and pulley assembly. The system controller includes functionality for selectively activating the motor to aid or resist the user in moving the weighted panels based upon the sensor information. The system controller further including a memory and communication unit for storing exercise information of the user.

Abstract: A manual stair step exerciser that simulates the exercise derived from climbing stairs including a support frame with a chain sprocket assembly having multiple equal spaced deployable steps thereon. A drive shaft pulley and belt assembly interconnects to an adjustable magnetic resistant flywheel for sustained user step input of kinetic energy for sustaining self-propelled tread induced motion during exercise.

Abstract: A safety barrier for use with a play apparatus such as a trampoline includes at least one support pole and a barrier element. A portion of the barrier element is detachably connectable directly or indirectly to the support pole, the barrier element having an erect configuration and a collapsed configuration. In the erect configuration the portion of the barrier element is connected directly or indirectly to the support pole and in the collapsed configuration the portion of the barrier element is not connected directly or indirectly to the support pole.

Abstract: An electromagnetically controlled wheel resistance adjusting device includes a motor, a magnetic tile, a potentiometer, a circuit board, a socket, a connecting rod and an output gear. The socket, the motor and the potentiometer are electrically connected to the circuit board, respectively. An external controller may, through the socket and the circuit board, provide power to the motor and control operation of the motor. The external controller may, through the socket and the circuit board, provide power for the potentiometer and receive an output voltage sent by the potentiometer. The motor drives the magnetic tile to move through the output gear and the connecting rod. The output voltage of the potentiometer varies with the rotation angle of the output gear. The external controller may drive the magnetic tile to rotate through the motor, and determine the moving angle of the magnetic tile through the output voltage of the potentiometer.

Abstract: 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 two 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.

Abstract: The present invention relates to an apparatus (100, 1001, 1002) for physical activity, comprising: a frame (101); a plurality of rollers (203, 204) rotatably connected to the frame (101); a belt (200) mounted on the plurality of rollers (203, 204) and revolving to define moving belt surfaces (201, 202) comprising: an activity belt surface (201) being configured for physical activity of at least one user (301, 701) and delimited by a side of the frame (101), and a return belt surface (202) being configured for revolving the belt (200) in a never-ending loop; the return belt surface (202) is elevated with respect to the activity belt surface (201).

Abstract: A motorized treadmill includes a base, an endless belt movable relative to the base for allowing a user to exercise thereon, a motor coupled to the endless belt for driving the endless belt to rotate, a current sensor coupled to the motor, and a controller in communication with the motor and the current sensor. The current sensor is configured to detect a motor current of the motor when using the motorized treadmill. The controller is configured to analyze fluctuations of the motor current to determine whether objects or children interfere with rotation of the endless belt. When the current sensor detects a current change not associated with the user of the motorized treadmill, the controller determines that the endless belt is interfered by objects or children and stops operation of the motor to slow or stop rotation of the endless belt.

Abstract: A strength training grip device including at least two joined segments, the joined segments dimensioned to at least partially surround a handlebar of a weight training equipment. Each segment includes an inner surface and at least one force sensor disposed across the inner surface, the at least one force sensor to measure force in at least one direction.
