There is described an integrated unweighted gait training system having an unweighting system comprising a computer controller; a gait measurement system in communication with the controller; and a display in communication with the computer controller adapted and configured to provide real-time feedback to a user of the integrated unweighting gait training system. The unweighting system may be a differential air pressure (DAP) unweighting system or a non-DAP unweighting system.

Climber exercise machine comprises a frame connected to a base through a base connection, the frame pivotable about the base connection. A right handle and a left handle are connected to respective right and left sides of the frame, the right handle moving within a first range of motion, the left handle moving within a second range of motion. A right pedal and a left pedal are connected to the respective right and left sides of the frame, the right pedal moving within a third range of motion, the left pedal moving within a forth range of motion. The right handle, the left handle, the right pedal, and the left pedal movable generally in the same plane. An angle between the frame and a plane parallel to an underside of the base is adjustable while the climber exercise machine is mounted by a user.

A swing practice device for emitting light at impact through self-generation enables an impact moment to be checked with the naked eyes without needing a battery by emitting light at an impact time point through self-generation during swinging by using a golf club, a baseball bat, and the like. The swing practice device includes a power generation magnet provided to a shaft so as to slide in the longitudinal direction of the shaft during swinging; a power generation coil provided on the circumference of a section in which the power generation magnet moves; a light-emitting lamp connected to the power generation coil so as to be turned on by the movement of the power generation magnet; and a magnet control means for preventing the movement of the power generation magnet at a set swing speed or lower.

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.

A system for analysis of user gait and to provide correction in form of haptic and visual feedback. This system comprises a motion and force sensors and a haptic actuator embedded in the user shoe insoles in communication with a smart-phone based analysis application, configured to calculate motion and orientation of the user feet in relation to the value, location and distribution of ground reaction forces measured by sensors located in the shoe insoles and after analysis of said forces and motion, to provide haptic feedback to the user foot instructing about the location (and timing) of pressure the user must apply to achieve an optimal gait.

A golf ball with embedded electronics to allow proximity to be tracked and to monitor golfer performance is disclosed. The golf ball comprises a processor connected to an accelerometer, communications circuitry, a spin detector, and memory, wherein the processor stores accelerometer data from the accelerometer and rotation data regarding rotation of the spin detector in the memory. The processor converts the data regarding the rotation of the spin detector into a rotation speed and a rotation direction, said rotation speed determined by a frequency of the data, and said rotation direction determined by a magnitude of the data. The communications circuitry is configured to communicate the accelerometer data, the rotation direction, and the rotation speed to a central interrogator for analysis of a golfer's performance.

A pitching interactive training system having of a mat against which a ball is thrown. The mat has an embedded electronic display of a strike zone broken down into subsidiary “zones” and an exterior perimeter of “zones” just outside the strike zone. The embedded sensors and electronics when hit with a pitch register a point value on a scoreboard. Assignment of values may be adjusted for each pitch by remote control for each batter depending upon the game situation. The electronic scoreboard registers whether a ball or a strike and values for each pitch and maintains a total score with a reset for each new batter. The embedded electronics and scoreboard are powered by battery and rechargeable via an attached electric cord plugged into a standard electrical outlet. An optional radar gun records the speed of each pitch. An optional high speed sports camera attached to the system allows measurement of pitch spin rotations, pitch release point, and captures the entire pitch delivery process for replay to aid coaching and visualizing pitch command.

Controlling weight during a movement includes receiving a set of parameters comprising a nominal weight. It further includes detecting speed during a concentric phase. It further includes progressively adjusting weight during the concentric phase based on the detected speed and the nominal weight.

Dynamic strength loading per movement includes determining progress within a given state of an exercise. It further includes controlling, as a function of the progress within the given state of the exercise, a force generated by a motor of an exercise machine.

An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.
