Aspects of the disclosure relate to methods, apparatus, and systems for optimizing an energy exerted on a performer falling from an elevated platform and impacting an airbag. A system is configured to determine a weight of the performer to fall from the elevated platform toward the airbag, measure a distance between the elevated platform and the airbag, and set an air pressure of the airbag based on the weight and the distance prior to the performer falling toward the airbag. The system is further configured to determine, while the performer falls toward the airbag, a velocity the performer will reach upon impact with the airbag, and adjust the air pressure of the airbag based on the velocity while the performer falls toward the airbag to optimize an energy exerted on the performer when the performer impacts the airbag.

A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive an activity metric. The processor is further configured to display, via the display system, the activity metric, wherein the display system is disposed in the eyewear so that the activity metric is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle α from a forward direction.

The present invention provides a device comprising a fastening ring configured to mechanically attach the device to a lacrosse stick, a display screen having a rectangular shape, the display screen attached to the front part, a first button positioned on one side of the display screen, a second button positioned on one side of the display screen and a third button positioned on one or more sides of the display screen.

A method of calculating an optimal effective distance and providing analysis data on the basis of wind prediction analysis data for an efficient hole strategy includes: a step (a) of collecting and storing wind analysis collection data for wind analysis in a golf course in a database of a management server through a data collector of the management server; a step (b) of analyzing wind information for each shot position in a individual course on the basis of the wind analysis collection data by means of a calculator of the management server which performs wind analysis in a golf course; and a step (c) of configuring a graphic user interface environment for wind analysis on the basis of the wind information analyzed through the step (b) by means of the calculator.

A method of predicting the likelihood of a post tee off golf swing or consecutive swings resulting in a ball being sunk in a hole; the method utilizing communication equipped cameras or communication equipped laser rangefinders at known locations to determine accurate ball lie information. Transmission of this location information in real time to a processing facility linked to a database of historical play information incorporating at least ball position information and golf course in order to calculate odds of success of the upcoming swing and/or subsequent swings.

A training, rehabilitation, and recovery system comprises an exercise apparatus including a user interface member coupled to a plurality of links and joints, brakes capable of resisting movement of at least a subset of the links or joints, and sensors capable of sensing movement at the joints or the user interface member. The system also includes a processor configured to receive from the sensors positional data of the links or joints over an initial movement of the apparatus by a user, from which positional coordinates of the user interface member are calculated and a reference trajectory is established. An end space is defined based on the reference trajectory. Over a subsequent movement of the apparatus by the user, the processor receives additional positional data and determines a completion of a repetition based on the positional coordinates of the subsequent movement and the defined end space.

A golf system includes a plurality of striking areas, each striking areas being associated with a respective set of targets. The golf system includes at least one sensing device for sensing one or more parameters regarding the travel of a physical golf ball. A processor is configured to: access a database including golf hole data, the golf hole data defining relative positions of a tee-off location and a pin location for a virtual golf hole; based on the one or more parameters regarding the travel of the physical golf ball, update a virtual location of a virtual golf ball; generate signals to provide an indication of which of the plurality of striking areas or corresponding set of targets a next shot is to be struck from or to; and generate signals to provide an indication of which target in a set of targets represents a direction of the pin location.

A system and method for using weather applied metrics for determining the impact of weather conditions on the flight of a football at an outside football venue. Historical and current data for weather parameters, including wind, air pressure, humidity, temperature, and rain, are obtained to calculate the influence of each parameter on the flight of a football. Weather instruments, such as weather sensors, anemometers, LiDAR and SODAR devices, weather consoles, data routing devices, and processors can be included in a system for using weather applied metrics to predict the flight of a football based on current weather conditions.

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 golf analysis assistance apparatus includes an input/output unit, a golf course data storage unit, a player data storage unit, a target score acquisition unit configured to acquire a target score throughout a course, the target score being set by a player, and a control unit. The control unit is configured to obtain an optimal solution at each hole that enables achievement of the target score throughout the course, the target score being set by the player, based on golf course data and player data.
