Methods for determining performance information for an object located within an area include obtaining magnetic field information for the area, measuring first magnetic field data when the object is located at a first position within the area, and determining performance information for the object within the area based on the magnetic field information for the area and the first magnetic field data.

Motion-related, information-indicating systems for football generate and present flight relevant information of a thrown football. These systems include a measuring device and an indicating device. In one embodiment, the system measures the spin speed of a football using a gyro. If the spin speed is higher than a preset value, then an LED light on the football is tuned on. A quarterback assesses his spin speed by whether the LED light is on or off. In another embodiment, the indicating device is an LED light positioned on a ring worn by the quarterback. A transmitter/receiver pair transfers signals from the thrown football to the ring. In another embodiment, the system measures the acceleration of a football using an accelerometer. Further the system indicates the acceleration value on an LCD display monitor positioned on the ground. A quarterback checks the LCD display to access the strength of his throw.

Some disclosed golf club heads include body having at least one raised sole portion and a cantilevered ledge extending down around a perimeter of the club head below the level of the raised sole portion. Some disclosed golf club heads include one or more sole openings in the body and a sole insert that is mounted inside the body over the sole openings. The sole can include weight tracks as well, and a rear weight track can extend between a toe side sole opening and a heel side sole opening. A crown insert can also be included that is mounted over an upper opening in the body.

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.

A smart soccer goal for tracking and communicating motion of objects includes a goal frame; a net coupled to the goal frame including a plurality of lights; and one or more sensors coupled to the goal frame. A first sensor of the one or more sensors is directed to detecting movement within and immediately near the smart soccer goal and a second sensor of the one or more sensors is directed to detecting movement outside of the smart soccer goal.

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.

This disclosure relates to systems, media, and methods for quantifying and monitoring exercise parameters and/or motion parameters, including performing data acquisition, analysis, and providing scientifically valid, clinically relevant, and/or actionable diagnostic feedback. Disclosed embodiments may receive real-time sensor data from a motion sensor or sensors mounted on a user and/or equipment while a user performs a test motion. Disclosed embodiments may also calculate a test motion profile based on the real-time sensor data, the test motion profile describing a multi-dimensional representation of the test motion performed by the user or computed motion profiles. Disclosed embodiments may include comparing the test motion profile to a template motion profile to determine a deviation amount for the test motion profile indicating how the test motion deviated from the template motion profile. Still further embodiments may correlate test motion profiles over time with health indicators.

A system and method for measuring motion properties of a movable object, such as a sporting device, wherein the movable object has an embedded magnetized unit creating a magnetic field. A measurement device, having a first magnetic field sensor positioned a known distance away from a second magnetic field sensor, is positioned in the vicinity of the movable object's trajectory, whereby the first and second magnetic field sensors output signals when the movable object passes within their respective proximities. A control module, that is responsive to the output signals created by the magnetic field sensors, is configured to record the times of output signal events. The control module is further configured to calculate motion properties, such as the speed and rate of spin, of the movable object based upon the recorded times of various sensor output events and the known distance between the first and second magnetic field sensors.

A pitching interactive training system having of a mat against which a ball is thrown. The mat has an embedded electronic display of a strike zone broken down into subsidiary “zones” and an exterior perimeter of “zones” just outside the strike zone. The embedded sensors and electronics when hit with a pitch register a point value on a scoreboard. Assignment of values may be adjusted for each pitch by remote control for each batter depending upon the game situation. The electronic scoreboard registers whether a ball or a strike and values for each pitch and maintains a total score with a reset for each new batter. The embedded electronics and scoreboard are powered by battery and rechargeable via an attached electric cord plugged into a standard electrical outlet. An optional radar gun records the speed of each pitch. An optional high speed sports camera attached to the system allows measurement of pitch spin rotations, pitch release point, and captures the entire pitch delivery process for replay to aid coaching and visualizing pitch command.

According to one aspect of the invention, there is provided a method for measuring ball spin, the method comprising the steps of: detecting information on a mark appearing in a region corresponding to a ball hit by a user in each of a plurality of images in which the ball is photographed; determining whether it is possible to directly calculate physical quantities related to spin of the ball on the basis of the information on the mark; and when it is determined that it is not possible to directly calculate the physical quantities related to spin of the ball on the basis of the information on the mark, estimating the physical quantities related to spin of the ball on the basis of physical quantities related to at least one of a speed and an angle of the ball or a club hitting the ball.
