Ball Strikes FoxTenn Sensor

Last weekend in a semi-final match in Estoril, a ball struck one of the on-court sensors used by the FoxTenn line calling system. Sebastian Korda hit a ball that tipped the net cord and went almost straight up. Before the ball struck the ground it came into contact with one of the black boxes installed at the bottom of the net that houses the sensors/cameras. That unlikely occurrence presents an interesting case study of the rules.
