A method and system for using a low resolution image of a golfer's swing for analysis is disclosed. Cameras obtain images of various portions of a golfer's swing. A computer calculates parameters associated with a golfer and a golf club from the images. Parameters include body angles, head position, shoulder positions, arm positions, hand positions, leg positions, foot positions, club shaft angles, and club head position. Different portions of the swing are captured using the cameras, including a static initial address, a backswing, a downswing, a forward swing, and a follow-through. A computer uses measured parameters from two or more portions of the swing to determine comparative parameters during different portions of the swing. The computer uses the parameters to generate swing analysis outputs, including swing characteristic information and/or swing profile information. A correlation table relates identified swing analysis outputs to particular recommendations to the golfer to improve the swing.

An exercise device comprises a flywheel, a driving assembly, and a control assembly. The driving assembly drives the flywheel to rotate. The control assembly comprises an angle sensor for measuring the change of angular displacement of the flywheel during a specific period of time. The control assembly calculates the angular velocity or the angular acceleration of the flywheel by the measured angular displacement during the specific period of time. The control assembly determines if the flywheel is to be stopped according to at least a criterion.

A fitness structure includes a bar having a first end portion and a second end portion, a pair of bar support portions provided at each side of the bar and having a plurality of bar support members to place the bar at a plurality of heights, a first load portion and a second load portion spaced apart from the bar to a certain degree and facing each other, a first cable coupled between the first end portion of the bar and the first load portion, a second cable coupled between the second end portion of the bar and the second load portion. Heights of the first load portion and the second load portion vary depending on a height of one of the plurality of bar support members at which the bar is detachably placed.

An adjustable dumbbell system may include a handle assembly, at least one weight, at least one sensor, and a computing device. The at least one weight may be selectively fixedly connectable to the handle assembly. The least one sensor may be positioned on the handle assembly. The at least one sensor may be configured to detect a handle assembly attribute indicative of whether the at least one weight is fixedly connected to the handle assembly. The computing device may be in communication with the at least one sensor and may be configured to receive information regarding the handle assembly attribute from the at least one sensor.

A golf club fitting apparatus and a method for fitting using the apparatus are provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle, effective loft angle, stroke plane, and aiming verification information. That golf club fitting apparatus includes a first opening for receiving a shaft, second openings for receiving a collimated light source, third openings for receiving angle indicators, and a recess for securing the collimated light source in an alternate configuration.

A resistive therapeutic device is disclosed such that upon a user applying torque a controller emits a signal to an electromagnetic resistance generating member. The controller detects a maximum torque applied by a user detects if the maximum torque applied by a user is less than or equal to a resistance setting. The torque resistance is variable from a neutral position to a maximum position, and the controller increases the resistance setting as a user moves a torque application member in a direction away from the neutral position that represents an increase in torque applied by the user. A control and user interface for a resistive therapeutic device includes an evaluation display of torque strength applied and displays an angle of rotation clockwise or counterclockwise directions ranging from 0 degrees to 360 degrees and a count of repetitive times a user has rotated at least 360 degrees in either direction.

A motion sensor package with an elastomer layer that encases the sensor electronics, including the sensors, a processor, an antenna, and a battery. The elastomer layer may provide shock isolation and water resistance to protect the enclosed electronics. Embodiments may also include an outer housing into which the elastomer encased package is installed. The outer housing may for example comprise two cylindrical sections that screw together to close the outer housing. In one or more embodiments part of the outer housing may be integrated into an item of sports equipment. Embodiments for golf may also include a golf club grip adapter that is inserted into the top of a grip, and which attaches to the outer housing containing the elastomer enclosed sensor package.

A sport combat training machine including a base assembly; a post; a shaft assembly having a spring adaptor; a mounting frame that mounts onto the post; a lower striking assembly having a first motor with a respective first adaptor having a first spring attached to a respective first lower striking arm; an intermediate striking assembly; an upper striking assembly including a second motor, with a second adaptor having a second spring attached to a respective first upper striking arm; and an electrical system having at least one computer configured with software to operate the first and second motors and a pedal for controlling the at least one computer. The intermediate striking assembly includes a body having a target area and at least one sensor. The sport combat training machine further includes a top plate assembly having at least one sensor.

Disclosed herein is a dynamic pendula stool possessing a foot, a leg secured to the foot, and a seat secured to the top end of the leg. The leg has a telescopic column that includes a lower part secured to a spherical foot with a diameter of 20-cm or less and an upper part with a free end having an articulation. The articulation has three degrees of freedom and is secured to the underside of the seat so that when a user rests against the seat, the leg forms an angle between 30 and 90 degrees with respect to the horizontal, thereby allowing an isometric contraction of the muscle groups of the lower limbs and of the abdominal girdle in the seated position. The stool is further provided with one or more sensors configured to send data signals to a remote electronic device.

An electronics module in a gaming device includes an inertial measurement unit (“IMU”) for detecting acceleration motion, angular movements, and an optics assembly to optimally calculate a moment of impact and to predict a virtual trajectory of a virtual golf ball or other hypothetical object. The virtual trajectory of the target object may be displayed on a display screen either on the gaming device itself, on a computer, or on a television display. A haptics member, such as a vibration or sound element is positioned in the shaft housing and actuated to simulate a ball impact when the shaft housing is indicative of a swing.
