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.

Audio systems and methods for obtaining location information are disclosed. A portable, wireless speaker that may include a beacon that a user may activate to remotely trigger a request for shot information, which may include location information of the user or speaker. The beacon may be wirelessly coupled to the speaker. The speaker may receive location information from a remote device, such as a GPS-enabled mobile phone. The shot information may be converted into an audio format for playback by the speaker. The speaker may pause the playback of the speaker to play out the shot information.

In accordance with at least one aspect of this disclosure, an exercise device can include a body configured to be gripped by a user, wherein the body is configured to be used for exercise, at least one sensor attached to the body and configured to sense a motion, position, and/or orientation of the body, and at least one controller configured to receive sensor signals from the sensor and to send sensor signals or data to a remote computer. The body can be an exercise bar or any other suitable shape.

An interactive baseball gamification system can be facilitated via the use of sensors, data tracking, gamification, and virtualization. A first user can play against a second user in real-time, near real-time, or based on historical user data. Additionally, the first user can be geographically remote from the second user. The interactive baseball gamification system can be used to train baseball players or baseball teams. Alternatively, the interactive baseball gamification system can be used for recreational purposes to pit users against each other.

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.

A method and device for guiding a runner along a predetermined running path including the steps: a) Determining the actual position of the runner by a GPS module; b) Assigning the actual position of the runner to a position along the predetermined path; c) Determining if the runner has to continue the predetermined path c1) straight ahead, or c2) by turning to the left or c3) by turning to the right; d) Controlling at least two light emitting elements arranged at or in a garment worn by the runner, wherein at least one left light emitting element is located in a left hand region of the garment and at least one right light emitting element is located in a right hand region of the garment, wherein d1) no activation of the light emitting elements is carried out in above case c1), d2) at least one left light emitting element is activated in above case c2), and d3) at least one right light emitting element is activated in above case c3).

Systems and methods for prescribing athletic activity to be performed by a user, and for adapting the prescribed athletic activity based on completed (e.g. ongoing) athletic performances by the user. A coaching plan may be automatically created that prescribes personalized athletic activities as a user trains towards a goal date. The athletic information may be received from one or more sensor devices associated with a user, and the coaching plan may be continuously or intermittently updated based on the received sensor data.

Embodiments provide apparatuses, systems, and methods associated with a location-aware autonomous self-propelled sports ball. The sports ball may detect its location relative to one or more locator tags and control its self-propelled movement based on the detected location. The locator tags may be worn by respective users of the sports ball and/or placed on the ground. The sports ball may operate in different modes that control movement of the sports ball relative to the one or more locator tags, such as tag, chase, auto-return, side-to-side, and race. Other embodiments may be described and/or claimed.

An exercise system enabling a user to safely, consistently, and restorably move from a first position to a second, desired position, and back to the first position. The exercise system may enable a user to engage their abdominal, latissimus, gluteal, biceps, triceps, spinal, pectoral, and other muscles. The exercise system may include arms arcuately extending from a central base, the arms including multiple restoration/tension bands coupled to the arms and central base at different locations to provide both resistance of arcuate movement away from the base (user moving from a first position) and arcuate restoration forces back towards the base during the completion of an exercise movement or set (user moving back to the first position after reaching a desired second position).
