A method and system of officiating a sporting event with a player on a field of play with a play boundary is disclosed. A ball sensor in a ball of sport and a player sensor in player equipment may be detected when breaking a detection field generated by a field generator along a play boundary. Play data and participant data may be sent to a processor to determine an officiating result, and the officiating result may be sent to an official's mobile device for confirmation.

A method for monitoring the motion of a sport ball that has been impacted by an individual during the course of an athletic activity includes the steps of a portable electronic device wirelessly receiving motion data from the sport ball, and the portable electronic device determining a point of impact based on the motion data, wherein the point of impact includes a location on a surface of the sport ball where the impact occurred.

An apparatus, methods and systems are provided for creating a shot information database comprising ball flight data combined with a user's intended golf shot type, the user's golf club selection, the user's setup position and dynamic swing adjustment made to produce the golfer's intended golf shot with the selected golf club to produce said golf shot. This invention presents to the user such information as a score, wherein said score reflects the accuracy of the user's golf shot. In addition, the ball flight data includes a trajectory angle, an elevation angle, a quadrant in a target plane comprising an x-y coordinate system coplanar with said target plane and a characterization of a type of golf shot produced by said golfer, such as a draw. Another embodiment of this invention performs a statistical analysis on said shot information to create basic and advance shot reports to assist a golfer or a third party to learn a golfer's strengths and weaknesses with respect to the user's ability to hit certain golf shots with certain golf clubs; in addition, the golfer is able to learn with setup keys and swing keys are more successful in hitting certain golf shots with certain golf clubs. In this manner a golfer or user is able to learn what it takes to improve his/her golf swing while better understanding their particular capabilities and tendencies. Another embodiment of this invention allows a golfer to practice indoors in a manner that simulates outdoor practice at a driving range, For golfer's who are visually impaired, this invention provides accurate feedback to a golfer who is visually impaired to the extent that they cannot see the flight of the struck golf ball. Said golfer benefits little at a driving range where they are unable to see the results of their golf swings This apparatus characterizes each golf shot using a particular practice ball which interoperates with the apparatus in such a way to enable said apparatus to acquire said ball flight data. Another embodiment of this invention allows a golfer to enter or speak remarks on the results of the previous shots or, more simply called post shot remarks. All shot information is stored in permanent storage for later historical performance analysis.

A sports ball system for calculating movement characteristics has a sports ball. The sports ball monitors movement characteristics of the sports ball. A wearable device receives data transmitted by the sports ball. The wearable device analyzes and displays the data transmitted.

A game ball configured for organized, competitive play and having a total mass. The game ball includes an inflatable bladder, a layer of reinforcing material surrounding the bladder, an elastomeric layer surrounding the bladder, and a plurality of cover panels positioned over the layer of reinforcing material and the elastomeric layer. The bladder has a bladder mass that is greater than 25 percent of the total mass. The elastomeric layer and the layer of reinforcing material have a collective mass that is less than 55 percent of the total mass. The game ball is formed without one or more of electronics, batteries and charging coils.

This disclosure relates to systems, media, and methods for providing near-instantaneous feedback from real-time motion sensor data. In an embodiment, the system may perform operations including loading at least one target motion trigger. Disclosed embodiments may receive real-time sensor data from the first motion sensor detachably fixed to a user. Additionally, disclosed embodiments may include calculating a motion profile based on the real-time sensor data, the motion profile describing a multi-dimensional representation of acceleration of a motion performed by the user. Disclosed embodiments may also include comparing the at least one target motion trigger to the calculated motion profile to determine if the motion performed by the user corresponds to the target motion. Further, disclose embodiments may include transmitting, based on the comparison, an instruction to provide an alert to a user.

The present invention compromises a novel softball training aid that accelerates the ability an understanding of throwing and spinning a softball in different orientations. In various embodiments the invention will help create and maintain a more effective pitcher and/or softball player

The present disclosure relates to systems and methods for elastic delivery, processing, and storage for wearable devices based on system resources. For example, a wearable apparatus may have at least one battery; at least one sensor configured to measure at least one property associated with a user of the wearable apparatus; at least one memory storing measurements from the at least one sensor and instructions; at least one transmitter configured to send data to a device remote from the wearable apparatus; and at least one processor configured to execute the instructions to: receive, from the at least one battery, an indicator of a charge; and based on the received indicator, sending a command to the at least one sensor to operate in a low-power mode or a high-power mode, the low-power mode having. a lower sampling rate than the high-power mode.

A liquid discharge head includes: an individual channel having an inlet and an outlet, the individual channel including: a nozzle, an upstream-side pressure chamber arranged between the inlet and the nozzle, a downstream-side pressure chamber arranged between the outlet and the nozzle, an upstream-side throttle channel connecting the inlet and the upstream-side pressure chamber, and a downstream-side throttle channel connecting the outlet and the downstream-side pressure chamber; a supply channel connected to the inlet and configured to supply liquid to the individual channel; a recovery channel connected to the outlet and configured to recover the liquid from the individual channel; an upstream-side actuator configured to apply pressure to the liquid inside the upstream-side pressure chamber; and a downstream-side actuator configured to apply the pressure to the liquid inside the downstream-side pressure chamber. The channel resistance of the downstream-side throttle channel is smaller than that of the upstream-side throttle channel.

An electronic golf aid system for assisting users with reading greens on golf courses includes a camera that captures images of the user's field of view, and an electronic display device with a display screen that displays captured images. A processor, which communicates with the camera and display device, is programmed to: receive signals from the camera indicative of images of a golf ball and a cup on the green; determine respective locations for the golf ball and cup; determine a perspective view of the topology of the green between the golf ball and cup from the user's point of view; determine, based on the green's topology, a proposed trajectory line from the golf ball's location to the cup's location; and direct the electronic display device to display the proposed trajectory line superimposed on the surface of the green as the green is shown in real-time on the display screen.
