A sensor device includes an inertial sensor and a holding member. The holding member holds the inertial sensor and is capable of being attached to and detached from an end face of a grip being part of a sports implement and having the shape of a shaft. The holding member includes a sensor-side coupling part. The sensor-side coupling part is capable of being attached to and detached from a grip-side coupling part on the end face of the grip by being moved relative to the grip in a first direction that forms an angle with an axial direction of the grip.

A golf swing analyzer system for analyzing a golfer's golf swing. An inertial measurement unit (IMU) may be used to capture data regarding the swing. The IMU may be oriented along a hosel-axis and a face-axis to reduce the complexity of calculations to determine the path of the swing. Two IMUs may be used to permit correction of captured data, different orientations of the IMUs to increase accuracy of captured data, and a doubling of the captured data. The IMU may include a magnetometer that cooperates with a magnet that is adapted to indicate the time at or near impact of the head of the golf club with the golf ball. An LED system provides visual information to a user regarding the swing while the swing is being made.

Systems and methods for tracking a sports ball assembly in real time during a sporting event are disclosed. A structure of the sports ball assembly is also disclosed. The sports ball assembly comprises at least one electronic circuit embedded or attached to a sports ball. The sports ball assembly is in network communication with a server processor via at least two receivers within a sports arena. The sports ball assembly generates and transmits UWB data packets comprising movement-related data for the sports ball assembly in real time at a predetermined rate. The at least two receivers receive the UWB data packets and transmit to the server processor with time stamps. The server processor is operable to determine a movement of the sports ball assembly based on the UWB data packets and the time stamps received from the at least two receivers.

A method, including scanning a golf club to obtain scanning information; inputting the scanning information into a processing system; using at least one camera positioned behind and in-line to a golf swing direction and at least one lighting unit to obtain a series of images of a golf club during the golf swing; converting the series of images into parameterized motion representations; using at least one radar to obtain a radar signal; inputting the parameterized motion representations and the radar signal into the processing system; receiving golf club parameters and golf swing parameters as an output of the processing system; and generating a visual model of the golf club and the golf swing in a virtual space using the golf club parameters and the golf swing parameters.

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 digital slope meter includes: a shaft extended in a longitudinal direction thereof and having a rolling groove formed on top thereof in the longitudinal direction thereof to allow a golf ball placed thereon to be moved down therealong, when the rear side thereof is tilted up in a state where the front side there is located on a green, and to then roll on the green from a discharging end formed at the front end thereof; and a measuring module located on the shaft to measure a moving distance and an isolated angle of the golf ball rolling on the green from the discharging end when the rear side of the shaft is tilted up.
