An apparatus includes a training area in the form of an enclosed space in which light levels can be controlled, at least one physical element related to a task for which an individual is to be trained, and a lighting arrangement. The lighting arrangement generates a background luminance level in the training area sufficient to cause the vision system of the individual to function in the mesopic or low photopic range of vision, and the physical elements are themselves illuminated by an illumination means. The luminance level of the physical elements is greater than the background luminance level.

Provided is a wearable device to provide guidance to a user related to a movement trajectory path of an exercise. The wearable device includes a band, a plurality of vibration motors, at least one processing unit, and a processor. The band is configured to be disposed on a body part to be moved in the exercise. The vibration motors are connected about the band and configured to vibrate when activated. The processing unit is connected to the band and is configured to determine motion data of the motion processing unit as the body part is moved in the exercise. The processor is configured to determine three-dimensional orientation of the band in relation to the trajectory path based on the motion data of the at least one motion processing unit, and configured to activate one or more of the vibration motors to provide guidance to the user based on the trajectory path.

Golf stroke training apparatus, as well as methods and systems to train a golfer to improve golf strokes, including putting strokes, wherein the golf stroke training apparatus provides a planar surface that can be levelled statically to the surface below it and can be adjusted by adding slope and/or pitch in quantifiable measurements and with a high degree of accuracy, wherein the repeatable golf stroke environments so provided permit repeatable and quantifiable golfer stroke actions and analysis and leading to golf stroke consistency.

A system and method for brainwave entrainment therapy that allows for targeted treatment of particular areas of the brain, particular neurological functions, particular neurological states, and combinations of areas, functions, and states. The system and method receive a neurological assessment identifying areas of the brain or neurological functions to be treated, select one or more treatment modalities and frequencies, select a treatment regimen, and apply brainwave entrainment using the modalities, frequencies and regimen while the subject engages in dual-task activities selected to stimulate the areas of the brain, neurological functions, or neurological states to be treated, enhanced, or altered.

An exercise rating and improvement system comprising: a feature amount extraction unit for extracting, from information obtained from a subject, a feature amount about exercise efficiency; an rating unit for rating exercise efficiency of the subject by comparing the extracted feature amount and a feature amount to be compared; and an improvement information providing unit for providing, on the basis of the rating result, information such that the feature amount of the subject approaches the feature amount to be compared.

A racket dampener swing sensor apparatus to obtain measurements of parameters relative to the player's performance while reducing vibration includes a dampener body having a body front side, a body back side, and a body perimeter. The body perimeter has a string channel to selectively engage a plurality of strings of a tennis racket. The dampener body absorbs vibration from the plurality of strings. An accelerometer and a microcontroller with memory are coupled within the dampener body to measure hit velocity for each shot type (forehand, backhand, serve, topspin, slice, or flat). A vibration sensor is provided to detect when a ball is struck. A transceiver is coupled within the dampener body to wirelessly communicate with an app on a smartphone or computer. A battery is coupled within the dampener body and a charge port is in operational communication with the battery.

A method may include obtaining sensor data from one or more activity sensors, each of the activity sensors being coupled to a respective area of a sports user. The method may include obtaining image data of the sports user and each of the activity sensors coupled to the sports user. The method may include identifying, by a machine learning module and based on the sensor data and the image data, a respective muscle associated with each respective area to which the activity sensors are coupled. The method may include identifying movement of the sports user based on the sensor data from the activity sensors and the identified body part. The method may include analyzing the identified movement of the sports user including evaluating a body posture of the sports user, identifying one or more movement patterns of the sports user, and/or performing an injury assessment for the sports user.

A system and method for evaluation, detection, conditioning, and treatment of neurological functioning and conditions which uses data obtained while a person is engaged in simultaneously in a range of primary physical tasks combined with defined types of associative activity, such as listening, reading, speaking, mathematics, logic puzzles, navigation of a virtual environment, recall of past stimuli, etc. The data from the physical and associative activities are combined to generate a composite functioning score visualization indicating the relative functioning of areas aspects of neurological functioning; including those in which deficiencies may be present, which are early indicators of possible neurological conditions. Through algorithmic recommendations combined with expert and user input, a conditioning regimen targeting neurological aspects of interest paired with periodic testing allows the user to track their progress in these areas over time.

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 a means for gripping and securing a ball positioned at the fore end, and 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.

A system for analyzing starts and acceleration phases in squat-style track and field events has: a launching stand, a plurality of wireless cameras, a technical analysis host, two foot tracking devices and a gyro group. The launching stand has at least one acceleration sensor and an adjusting support connected to two pedals. The technical analysis host is connected to the acceleration sensor and the wireless cameras, the acceleration sensor actives the wireless cameras to collect instantaneous speed data of a runner, and the technical analysis host generates a 100 m speed curve L1 of the runner, and the 100 m speed curve L1 includes a continuous reduced acceleration section L2. The two foot tracking devices are installed on two feet of each runner. The gyro group have a first gyro, a second gyro, a third gyro and a fourth gyro.
