The present embodiments provide systems and methods for aggregating measurements captured by different technologies during a golf swing. By capturing measurements using different technologies, more accurate measurements may be provided to a user by selecting from the measurements, offsetting measurements based on the technologies used, and aligning measurements between devices. Further, by aggregating measurements received from different devices, additional features and functionality may be provided to the user that is absent from any one device used alone. Additionally, by storing the aggregated measurements, users, club fitters and instructors may access and leverage larger databases of measurements to better understand the user's golf swing and to provide better recommendations and instruction to the user.

A ball, and in particular a baseball or softball, including one or more sensors such as accelerometers and/or inertial measurement units, and systems and methods using the same to improve a pitcher's pitching performance are described herein. In some embodiments, the ball may include one or more inertial measurement units and/or accelerometers capable of monitoring motion of the ball while it is thrown. Various types of pitches may be selected, and in response to the inertial measurement unit(s) and/or accelerometer(s) detecting certain parameters corresponding to a selected pitch, one or more indicators may be caused to perform an action. For example, one or more illuminating elements located on the ball may turn a first color in response to detecting parameters corresponding to the selected pitch.

The present invention comprises a unique system and method for providing adaptable ball delivery and tracking, including appropriate sensor hardware, interactive gameplay user interfaces and point of sales systems. The system and method of the present invention are especially relevant to baseball and softball as, among other components, the system comprises a vertical, ground-up soft toss ball delivery mechanism, automated player and ball-tracking devices, and ball-collection and transport systems. The ball collection and return components eliminate the need for “fielders” and enable the creation of the first “batting range”. The vertical, ground-up soft-toss pitch machine further enables the first multi-story batting facility with player batting bays that open onto a sports field. Further, certain embodiments of the present invention integrate hitting screens, augmented reality display and simultaneous coordination of gameplay and communication between players, regardless of the players' physical location.

A golf ball including a spherical body, first regions, and second regions. The spherical body includes a core layer and a cover layer made from a synthetic resin covering the core layer. Dimples are formed in a surface of the cover layer. First regions that are electrically conductive are formed on a surface of the spherical body. The first regions are formed on a spherical surface having a center of the spherical body as a center. The first regions are positioned at six vertices of an imaginary regular hexahedron such that the vertices are positioned on the surface of the spherical body and, thus, six of the first regions are formed. The second regions are formed in areas of the surface other than where the first regions are formed. The second regions have a radio wave reflectance lower than that of the first regions.

In a measurement unit, a primary acceleration sensor is fixed at the center of gravity of a flying object or at a position within a certain error range from the center of gravity. A secondary acceleration sensor is fixed inside the flying object so as to be spaced from the center of gravity of the flying object. In a measurement apparatus, an acquirer acquires a primary acceleration measured by the primary acceleration sensor during flight of the flying object and a secondary acceleration measured by the secondary acceleration sensor during the flight of the flying object. An estimator estimates a spin rate per unit time of the flying object from the acquired primary acceleration and the acquired secondary acceleration using maximum likelihood estimation.

An exercise device comprises a flywheel, a driving assembly, and a control assembly. The driving assembly drives the flywheel to rotate. The control assembly comprises an angle sensor for measuring the change of angular displacement of the flywheel during a specific period of time. The control assembly calculates the angular velocity or the angular acceleration of the flywheel by the measured angular displacement during the specific period of time. The control assembly determines if the flywheel is to be stopped according to at least a criterion.

In one general aspect, an apparatus to monitor movement of an object may include an input device configured to trigger pre-selection of a type of performance of the object, at least one sensor used to measure a motion parameter of the object, a controller configured to receive the motion parameter of the object and compare the measured motion parameter with a motion reference, and an output device configured to display, in real-time, a feedback information based on the comparison.

A method for determining a relative performance measure between at least two players in a sport, comprising: receiving position information relating to each of the players and a sporting projectile as each player hits or receives the sporting projectile, and determining, based on an analysis of the position information, the relative performance measure between the players.

A sensor system and method of using the system synergistically to improve the accuracy and usefulness of measured results is described. The system is comprised of electronically linked components that act as markers to trigger events, producers that gather data from sensors and aggregators that combine the data from a plurality of producers using triggers from marker devices to select the data of interest. The system is shown to be applicable to selection of data regions of interest and to analysis of the data to improve accuracy. The analysis of the data of any particular sensor within the system makes use of extrinsic data, being data generated by other sensors and intrinsic data, that is data or data limits that are known to be true from nature, laws of physics or just the particular information the user wants to acquire. The system is demonstrated on the analysis of Doppler radar measurements of a thrown object.

A golf target system featuring a hitting bay including a golf ball launch monitor system, a playing area including a plurality of illuminated panels, and a controller in communication with the golf ball launch monitor system and the plurality of illuminated panels, wherein the controller selectively controls the illumination of the plurality of panels to define one or more visual targets observable from the hitting bay and receives information from the golf ball launch monitor system such that, when a golf ball is hit from the hitting bay towards the playing area, the golf ball launch monitor system communicates data to the controller sufficient for the controller to identify a landing position of the golf ball with respect to the one or more visual targets.
