Interactive sports ball and sports management system

A sports management system comprising:

• an interactive sports ball, comprising:
• a body;
• a sensor arrangement having
• a first sensor, embedded within the body, to measure acceleration data associated with the ball, and
• a second sensor, embedded within the body, to measure rotational data associated with the ball;
• and
• a communication module operatively coupled to the sensor arrangement and configured to transmit the measured acceleration and rotational data;
• a processing unit communicably coupled to the communication module to receive the measured acceleration and rotational data, wherein the processing unit is configured to:
• generate a series of sequential measurements corresponding the measured acceleration and rotational data,
• calculate a variance using a set of sequential measurements from the series of sequential measurements,
• detect a contact event if the calculated variance exceeds a predefined event threshold, and the processing unit is configured to select the set of sequential measurements from the series of sequential measurements based on a dynamic sliding window;
• an imaging system for generating visual data of an interactive sports game;
• and
• a server operatively coupled to the imaging system and the processing unit, configured to synchronize the detected contact event with the generated visual data to enable management of the interactive sports game.
