Apparatus, systems, and methods for monitoring the performance of an individual during a fitness activity are disclosed. A method of monitoring the performance of a participant engaged in a fitness activity includes receiving a GPS signal during the fitness activity at a portable fitness device used by the participant; determining participant performance data based on the received GPS signal; at a stationary position beacon, transmitting location data associated with the location of the stationary position beacon; at a mobile participant receiver supported by the participant, receiving the location data from the stationary position beacon; and modifying the participant performance data based on the data received from the stationary position beacon.

Systems, apparatus, and methods for capturing data related to athletic performances. Some methods comprise displaying a site map for the performance and accepting a selection of a target for the performance. Various methods comprise estimating, based on the user location, the initial location of the object and recording data regarding the performance. Moreover, some methods also comprise using a satellite-based map as the site map. If desired, the estimating comprises sensing a pause in the changing user location. Some methods further comprise estimating a trajectory of the object using the initial location of the object and a portion of the trajectory. In some scenarios, methods comprise capturing a location of the object at the ending of the performance. The recording can further comprise capturing a video of the performance. Furthermore, these methods can comprise capturing subjective information regarding the performance.

In one aspect, an example system includes an arrow nock configured to couple to an arrow, a transmitter coupled to the arrow nock, and a controller. The controller is configured to (i) determine that the arrow has been shot from a bow and (ii) responsive to determining that the arrow has been shot from the bow, cause the transmitter to transmit a beacon signal at a variable rate that varies based on an amount of time elapsed since determining that the arrow has been shot from the bow.

Disclosed herein are various systems and methods for tracking and improving workout. As disclosed herein, exercise data associated with a user is received from a user device. Based on various other characteristics disclosed herein, the system may identify one or more known exercises from within the exercise data and then analyze the data related to the one or more known exercises to determine workout metrics. In some embodiments, the system may further evaluate the workout metrics using various techniques disclosed herein, and based on the evaluation a label may be associated with the workout metrics. The label and/or workout metrics may then be saved and/or provided to a user or another individual, such as a personal trainer.

According to the present invention, provided is a system for providing golf information, the system including: a green photographing unit for photographing an image of an area including a green on a golf course and communicatively connected to a communication network to transmit green image data to an outside; a golfer terminal that is carried by a golfer on the golf course and communicatively connected to a communication network to transmit golfer position data to the outside; and an information providing server that is communicatively connected to the communication network to generate golf information using the green image data and the golfer position data and transmit the generated golf information to the golfer terminal.

A system configured to be coupled with a participant of an activity. The system comprises: a participant activity monitoring unit configured for monitoring a performance of the activity by the participant; an activity information module configured for storing performance information corresponding to the activity; and a participant performance correlator configured for delivering comparative performance data based on the monitored performance of the activity by the participant and the stored performance information.

An electronic tracking system for assisting a user in determining distances to landmarks and objects in a sporting environment includes a user tracking system for determining the location of a user, a heads up display for displaying information to the user, and a processor operable to communicate with the user tracking system and the heads up display. The heads up display is designed to be worn on the user's head, and to display an image within the user's field of view. The processor is programmed to determine a distance between the user's determined location and an object or a landmark on. This information is displayed via the heads up display as a numeric representation of the determined distance.

To provide a highly reliable, cost-effective traveling collector that can determine the positions of fallen objects, such as balls, on the ground using a simple method, or determine the correct positions of fallen objects, such as balls, on the ground only by improving software and without the need for significant changes to hardware. The traveling collector includes a count sensor as a sensor for detecting the position of each collected ball at a position detected by a satellite positioning system, for example. A controller determines a position, which is obtained by reflecting, based on the positional information on the ball collector at a time point when the ball was counted by touching the count sensor, the movement distance of the ball collector from the time each ball was picked up from the ground by a ball collection wheel till the ball was counted by touching the count sensor in a direction opposite to the traveling direction of the ball collector at that time, as the actual position where each ball was picked up.

A ball machine comprising an imaging system to capture image data and a processor configured to, for a frame of the image data, analyze the image data using a neural network to detect a plurality of persons, determine a coordinate position on a playing surface of each of the plurality of detected persons, extract features of each of the plurality of detected persons, generate a first set of feature vectors corresponding to the plurality of detected persons, associate a first feature vector to the coordinate position on the playing surface of a first detected person to generate a first unique identifier, associate a second feature vector to the coordinate position on the playing surface of a second detected person to generate a second unique identifier, and control the ball machine to launch balls based on first settings corresponding to the first unique identifier and second settings corresponding to the second unique identifier.
