An apparatus for natural torso and limbs tracking and feedback for electronic interaction with fall safety support. The apparatus comprises a body harness worn on the body of a user, a support structure designed to bear the weight of the user in the event of a stumble, trip, or fall, and a plurality of tethers attached at one end to the harness and at the other end to the support structure. One or more sensors are integrated into the system to measure aspects of the user's movement and used as input to control a computer system. In the event of stumble, trip, or fall, all of, or a portion of, the user's body weight is borne by the tethers as a safety mechanism to prevent injury. The system is designed to be used with virtual reality systems wherein the user's vision is blocked or obscured by a virtual reality visor.

A system and methods for custom-fitting golf clubs and golf club components is disclosed. Data is generated by a tracking device as a plurality of golf swings are performed by an individual. The data comprises motion and orientation information associated with a golf ball and with a golf club. The data is displayed using a graphical user interface. A plurality of shot characteristics is determined from the data. The shot characteristics are used to recommend golf clubs and golf club components that adjust a golfer's swing where the golfer exhibits the plurality of shot characteristics.

A display board system for football coaching applications is provided. The system enables football coaching staffs to communicate any convey information to on-field players, such as the personnel types of the opposing team or the specific play call for the ensuing play. The system includes a visual display board, a control device, and a control application. The display board includes one or more rows of illuminating numbers that displays any selected set of one or more numerical digits for viewing by the on-field players. The control device is in electronic communication with the display board via wired or wireless connection and is configured for use by the coaching staff to input the desired information for display on the display board. The control application is a programming application configured to run on the control device to enable operation of the control device to display information on the display board.

The present disclosure is directed to a body-worn sensor-based system for evaluating the biomechanics and the motor adaptation characteristics of postural control during a sport activity such as a golf swing. Various embodiments use sensors such as accelerometers, gyroscopes, and magnetometers to measure the three-dimensional motion of ankle and hip joints. In several embodiments, additional sensors attached to other body segments are used to improve the accuracy of the data or detect particular instants during the swing (e.g., top of back swing, instant of the maximum speed of arm, and instant of ball impact). In a golf embodiment, the system combines the measured data in conjunction with a biomechanical model of the human body to: (1) estimate the two-dimensional sway of the golfer's center of mass; (2) quantify and evaluate the golfer's balance via his/her postural compensatory strategy; and (3) provide visual feedback to the golfer for improving dynamic postural control.

An expiratory, vibratory therapy device (100, 200 300, 400) includes a compliance meter (104, 204, 304, 404) having a cylinder (110, 210, 310, 410) with a piston (111, 211, 411) movable along its length. The piston is urged by a spring (116, 226) to one end of the cylinder. The opposite end of the cylinder has an air inlet (120, 123, 219) normally closed by a springloaded occluder (129). The occluder (129) is moved to open the air inlet when the patient exhales in the prescribed manner. This allows some air to enter the cylinder and enables the piston to be displaced. The piston is coupled to a flag (106, 206, 306, 406) visible to the patient. When the correct number of prescribed breaths have been made the piston displaces the flag to indicate completion of the therapy.

An apparatus and method of providing heat to hand-holding locations on a lacrosse stick shaft including a heating emitting element and a user-operable control. The apparatus and method may include one or more resistive heating elements connectable to a power source such as a battery. Charging of the power source may be by plug in charging, kinetic energy charging, contact charging, inductive charging, or by replacement of a battery. The apparatus and method may be configured for mounting within the stick shaft, for being mounted in an end piece at the butt end of the shaft, or being positioned on the outside of the shaft as a sleeve or wrap. The apparatus and method may include a chemical heating apparatus or phase change heating apparatus positioned within or on the stick shaft. The user control may be mounted in or on the end piece at the butt end of the shaft. An indicator may provide information to a user regarding status states of the operation of the lacrosse stick shaft heating or recharging.

A treadmill includes a deck, a first pulley disposed in a first portion of the deck, a second pulley disposed in a second portion of the deck, a tread belt surrounding the first pulley and the second pulley, and a platform incorporated into the deck.

A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a brake that is structured to apply a selectively variable resistance against rotation of the shaft relative to the structural frame. A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a gripping member mounted to the structural frame and structured to adhere to an external support surface. A method includes operating the FEPS device by rotating the shaft.

Exercise systems are provided that comprise at least a weight-supporting apparatus, the weight-supporting apparatus being configured for use with an upright exercise equipment apparatus and for at least one of receiving or supporting a weight-bearing component, an integrated scale and an integrated weight sensor, a digital display configured to at least display a weight data detected by the integrated scale and the integrated weight sensor, the weight data including at least an indication of a weight supported on the weight-supporting apparatus, a distributed network, and a server comprising a processor and one or more memory storage areas, the processor being configured to transmit the weight data over the distributed network to one or more remote devices, the one or more memory storage areas being configured to store the weight data on the server. A method of using an exercise system is also provided.

A treadmill system includes a deck, an endless tread belt covering at least a portion of the deck, a position sensor that senses a position of a user when the user is on the tread belt, and a control module that adjusts a speed of the tread belt in response to an output of the position sensor.
