Patent ID: 8095081

Claim:
A device for hands-free push-to-talk functionality, comprising: a hands-free push-to-talk sensor or switch including at least one of an air pressure sensitive switch, and a tilt sensor for sensing a change in a direction of force due to gravity on the tilt sensor when the tilt sensor is tilted more than a predetermined angle from a zero or normalized angle, wherein the hands-free push-to-talk sensor or switch is operable by at least one of the air pressure sensitive switch sensing a change in air pressure and the tilt sensor sensing a change in the direction of force due to gravity on the tilt sensor when the tilt sensor is tilted more than the predetermined angle from the zero or normalized angle; means to control operation of a communications device in response to signals from the push-to-talk sensor or switch, wherein the push-to-talk sensor or switch comprises the tilt sensor, wherein a transmit mode of the communications device is activated in response to the tilt sensor being tilted more than the predetermined angle from the zero or normalized angle of the direction of force due to gravity for a predetermined time duration; and means for maintaining the communications device in the transmit mode in response to at least one of detecting a voice signal or the tilt sensor being tilted more than the predetermined angle after a selected time delay.
