A golf launch monitor is configured to determine a flight characteristic of a golf ball. The golf launch monitor includes two low-speed cameras, a trigger device, and a processor. The trigger device is configured to detect a golf swing. The processor is configured to instruct, upon the trigger device detecting said golf swing, the first camera to capture the first ball image; instruct the second camera to capture the second ball image after a time interval, wherein the time interval is less than the first frame rate and the second frame rate; and determine, based at least in part on the first ball image and the second ball image, the flight characteristic of the golf ball.

A system and process for training a user's sports swing to maintain arm position and body rotation so as to promote a proper swing arc. The system includes a waist wrap having one or more attachment area on an outer surface. The system also includes one or more training blocks configured for attachment to the attachment area depending upon the type of swing being practices. The process promotes a proper swing arc by indicating incorrect arm position and/or body rotation through excessive contact between the user's arms and the training blocks during the swing. The goal of the system and process is to train a user's muscle memory for the correct arm position and body rotation in a proper swing arc.

An isokinetic rotational exercise device provides for training and collection of information of a knee joint as it rotates. The isokinetic rotational exercise device includes vertical supports attached to a base frame that provides for an inclusion of rotational foot plates. The rotational foot plates are connected to cables of a pulley system that allows for an ability to add resistance of free weights and resistance tubing. Bottoms of the rotational foot plates include sensors to measure rotational degree, and the corresponding information is sent to a processor for display on a monitor on the isokinetic rotational exercise device or to an external device. A degree of force used to turn the rotational foot plates when the resistance is added is data collectable through force sensors in the cables of the pulley system.

A tennis ball retriever for retrieving a tennis ball on and about a tennis court and for controllably releasing the ball includes a front-end ball collector having two spaced-apart blades defining a ball collection space. The retriever includes one or more detents for retaining the collected ball in the collection space until a programmed or manually-directed release toward a target location such as a tennis baseline. The retriever includes a processor-controller for controlling and directing the retriever during a retrieval session. The retriever may be remote-controlled such as by voice commands.

Disclosed is a belay device for climbing including an automatic winder including a pulley and a rope. The device includes an electric motor configured so as to apply a torque to the pulley and an encoder coupled to the pulley. The motor is controlled using the encoder according to the rotation of the pulley so as to modulate the torque applied to the pulley according to at least: —an assistance mode in which the torque applied by the servomotor to the pulley drives a pulling of the rope which assists the climber in his climb; and —a fall mode in which the torque applied by the servomotor to the pulley blocks a fall of the climber or slows it to a speed less than 3 m/s. Also disclosed is a climbing game system with virtual or augmented reality using such a belaying device.

An automatic ball launcher includes a ball feed control system that includes a meter wheel with radially-spaced ribs or grooves to selectively block and pass balls to the flywheels of the launcher. The meter wheel rotates to selectively block and release a single ball to pass at a time. The controller of the launcher can be programmed to stop the meter wheel when a ball has been metered by monitoring the current at peak of the motor driving the meter wheel. A meter-event can be determined to have occurred when the current of the drive motor drops to a trough by a pre-set magnitude following a rise to a peak value. A remote control can be provided for the user to operate the launching machine and adjust a plurality of parameters.

An apparatus, system and method for ski training are disclosed herein for providing feedback to a skier regarding the orientation of their skis. The apparatus, system and method measure various distances between a first ski and a second ski, determine an angle between the first ski and the second ski based on information representative of various distances; and provide an indication of the measured angle.

Apparatus, systems, and methods are provided for measuring and analyzing movements of a body and for communicating information related to such body movements over a network. In certain embodiments, a system gathers biometric and biomechanical data relating to positions, orientations, and movements of various body parts of a user performed during sports activities, physical rehabilitation, or military or law enforcement activities. The biometric and biomechanical data can be communicated to a local and/or remote interface, which uses digital performance assessment tools to provide a performance evaluation to the user. The performance evaluation may include a graphical representation (e.g., a video), statistical information, and/or a comparison to another user and/or instructor. In some embodiments, the biometric and biomechanical data is communicated wirelessly to one or more devices including a processor, display, and/or data storage medium for further analysis, archiving, and data mining. In some embodiments, the device includes a cellular telephone.

A method, apparatus, or system for reducing gait asymmetry is disclosed. The method, apparatus, or system may include measuring one or more gait parameters of an individual; calculating a joint metric based on the measured one or more gait parameters; and signaling an adjustment of an amount of one or more perturbation techniques based on the joint metric for reducing asymmetry in a gait pattern of the individual. The one or more perturbation techniques include asymmetric rhythmic auditory cueing making a first audible cue with a first cue duration for one leg of the individual and a second audible cue with a second cue duration for another leg of the individual. Here, the first cue duration is different from the second cue duration. Other aspects, embodiments, and features are also claimed and described.
