Smart ball

A smart ball comprising:

• an inner sphere;
• and
• an outer sphere that ensconces said inner sphere, said outer sphere comprising at least two halves stitched together to form two spaced apart seams so as to completely cover said inner sphere, said inner sphere further comprising:
• a cylindrical cavity, running through a central core of said smart ball, said cylindrical cavity formed by drilling into said inner sphere from an operative top side;
• and
• a sensor assembly placed, substantially, at the centre of said cylindrical cavity, along a reference plane that divides the two seams in order for them to be equidistant from an imaginary line which form the reference plane when extended through the mass of the ball, thereby ensuring that orthogonal measurements of said sensor assembly are aligned with orthogonal axes of said smart ball, wherein said sensor assembly comprising a microcontroller communicably coupled with a clock for recording sensed events, said clock being also communicably coupled to another remote sensor assembly to record said another remote sensor assembly's sensed events with respect to the same clock in order to provide a single-clock session of sensed events comprising data from said ball's sensor assembly in synchronisation with data from said another remote sensor assembly.
