Spalding’s previous in-house attempts to incorporate wireless power into their ball-based training system continuously failed. Not only were they unable to reach desired power and data levels, but the internal hardware diminished the smart basketball’s bounce-back performance. In other words, the initial solution did not bounce, dribble or throw like a standard basketball—rendering this advancement in training impractical.
Like Honeywell and Prevent Biometrics, Spalding did not need their wireless power solution to be compatible with other external devices (i.e. smartphones) so NuCurrent developed a proprietary wireless power system. The result was a high-frequency, low-power solution to deliver 2-5W via 6.78MHz that achieved the required power levels and system efficiency. By selecting and uniquely housing NuCurrent’s patented MLMT PCB coils within the basketball, NuCurrent was also able to improve the user experience by making it feel and respond just like a normal basketball.
Together, Spalding and NuCurrent addressed several challenges to create the first-ever connected-product training system.
