Patent ID: 7697962

Claim:
A cellular communication device comprising: a housing having a front section and a rear section complementary to the front section such that the front and rear section align and mate together; a cavity formed by the mating of the front and rear section of the housing; an electronic circuit board having a microprocessor, the electronic circuit board and microprocessor located within the cavity; an accelerometer, a tilt sensor and a thermal sensor operably connected to the microprocessor, the microprocessor for detecting displacement of the cellular communication device from the ear of the user during communication in response to the accelerometer, the tilt sensor and the thermal sensor; a toggle switch operably connected to the microprocessor for toggling the cellular communication device into speakerphone mode upon detecting that the cellular communication device has been displaced from the ear of the user; a sound indicator operably connected to the microprocessor for indicating to a person calling the cellular communication device that the cellular communication device is in speakerphone mode; a display operably connected to the microprocessor and embedded in the front section of the housing for displaying information; and a light source operably connected to the microprocessor for illuminating the display, wherein the light source intensifies once it has been detected that the cellular communication device is displaced from the ear of the user.
