In one example, we describe a method and system for invitation to games or sports. For example, when the user uses our system (PlayUs), she or he gets connected to others very easily (e.g., in the city's “Open League”). This way, the player/user is immediately presented with a feed of all recent activities and has immediate access to all active players in the area. The user can also access his/her friends through the social networks, to increase participation very rapidly. One can also make groups and find new friends using our app (mobile application), e.g., with mobile phones or devices. One can also be discovered by others, depending on the level of privacy desired or previously set. Many different variations or combinations are also shown here.

A head guard is provided. The head guard includes one or more sensors as part of an sensory input and communications system. The head guard wirelessly communicates data to remote computing devices for intelligent data collection.

The present invention discloses an intelligent household air purification cabinet type body-building apparatus, comprising a box body, a running machine, an air purifier and a power supply. The intelligent household air purification cabinet type body-building apparatus is further provided with an intelligent control system which comprises a controller, a central control computer, a pressure frequency detection device, an audio device, a display device and a signal receiving and transmitting device. A use method of the body-building apparatus comprises five steps of facility unfolding and need setting, environment preparation, body-building process, statistical analysis of body-building completion, and folding. The present invention has the advantages of small occupation space, complementary functions, no need of adding a power supply, supply of body-building environment beneficial to a human body, convenient operation and capability of long-term sustainable improvement.

Techniques for automatic tracking of user data for exercises are disclosed. In one aspect, a method of operating a wearable device may involve determining that a user of the wearable device has started an exercise, activating the GPS receiver in response to determining that the user has started the exercise, and detecting a time at which the GPS receiver achieves an initial GPS fix of a location of the wearable device. The method may further involve logging, based on output of the one or more biometric sensors, a first set of user data during a first time interval between the start of the exercise and the detected time of the initial GPS fix, and back-filling an exercise route of the user during the first time interval based on the first set of user data.

An exercise device includes a frame, an upright portion of the frame, a movable element connected to the frame and movable in the performance of an exercise, a first display connected to the upright portion of the frame, and a second display connected to the frame.

An exercise device includes a frame, a movable engagement surface connected to the frame and movable in the performance of an exercise, and a display located adjacent to or below at least a portion of the movable engagement surface.

Systems and methods providing statistical analytics of golf performance for coaching including text, tabular, graphic, and image-based outputs that include trends information for the golfer, all based upon actual golf play on course situations, wherein the golfer inputs shot data during play, without interrupting the flow of the game, and uploads the shot data for analytics and review online, and wherein all information related to a given user are reviewable by an authorized coach user through a web-based coach access account. The system is further operable to provide the coach user rights for providing corrective or instructive feedback to the user, including visual recommendations such as modified target areas.

Systems and methods for golf analysis including a tag coupled to a golf club providing statistical analytics for coaching including text, tabular, graphic, and image-based outputs that include trends information for the golfer, all based upon actual golf play on course situations, wherein the golfer inputs shot data during play, without interrupting the flow of the game, and uploads the shot data for analytics and review online, and wherein all information related to a given user are reviewable by an authorized coach user through a web-based coach access account. The system is further operable to provide the coach user rights for providing corrective or instructive feedback to the user, including visual recommendations such as modified target areas.

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.

Provided is a smart golf bag system. The system includes a computing device coupled to a bag and a server coupled to the computing device. The system may include a sensor system coupled to the bag, wherein the sensor system communicates with the computing device. The system tracks golfer data, such as distance hit with each club used in a round of golf, the weather, time of day and the like. The data is stored and aggregated in the server and may be analyzed to suggest clubs based on the distance to the hole, etc.
