Patent attributes
A control box with control box hardware has an ON operative orientation. A primary printed circuit board has primary software operative in response to the orientation. The primary software when in the operational orientation functions to disseminate a blocking/filtering signals within a predetermined operational controlled zone. A digital wireless device performs normal digital wireless device functions. Digital wireless device hardware functions for switching between an inoperative orientation and an operative orientation. A secondary printed circuit board/software has secondary software operative to switch to the inoperative orientation in response to the digital wireless device entering the operational controlled zone to preclude the digital wireless device from performing normal digital wireless device functions.
