1. A mounting assembly for sensing correct device orientation, comprising:

  • a portable device;

    a base geometrically conformed to mate with the portable device;

    at least four Hall effect sensors coupled with the portable device;

    at least two magnets coupled with the base, the magnets and the Hall effect sensors being cooperatively arranged such that proximity of the magnets causes at least one of the Hall effect sensors to output an altered voltage signal when orientation of the portable device in the base is incorrect;

    wherein at least a first of the Hall effect sensors outputs the altered voltage signal when an orientation of the portable device in the base includes correct front-to-back and incorrect top-to-bottom orientation, and wherein at least a second of the Hall effect sensors outputs the altered voltage signal when an orientation of the portable device in the base includes incorrect front-to-back and incorrect top-to-bottom orientation; and

    an alert system that, upon receiving the altered voltage signal from one of the first Hall effect sensor and the second Hall effect sensor, outputs an alert indicating that orientation of the portable device in the base is incorrect.
