Patent Images
1. An accessory for a mobile communications device comprising:
- a cradle adapted to receive a mobile handset;
a power cord capable of being removably attached to the mobile handset;
a hall effect sensor placed in the power cord;
a magnet placed in the cradle;
a control circuit coupled to the hall effect sensor for sensing and transmitting a state of the hall effect sensor;
a speaker configured to be heard from several feet away coupled to the control circuit adapted to change states based on the state of the hall effect sensor;
a microphone coupled to the control circuit adapted to change states based on the state of the hall effect sensor;
wherein the magnet is adapted to change states of the hall effect sensor based on proximity and orientation of the magnet to the hall effect sensor.

Abstract
The hands-free car kit allows a mobile handset to enter and exit privacy mode without the user having to press a privacy button. The simple act of picking up the mobile handset out of its cradle switches the hands-free car kit from hands-free mode to privacy mode. When the mobile handset is installed in the cradle the hands-free car kit enters hands-free mode. If the mobile handset is removed from the cradle the hands-free car kit enters privacy mode.
