Vehicle intercom controller
First Claim
1. A method for controlling a communication system comprising at least one PTT and at least one microphone which has an “
- on”
state and an “
off”
state and is “
on”
whenever the PTT is activated, said method comprising the steps of;
detecting activation of the PTT, detecting deactivation of the PTT, and changing the state of the microphone to “
off”
when the PTT is deactivated within a period of time after activation of the PTT which is equal to or less than a predetermined short period of time only if the state of the microphone was “
on”
prior to activation of the PTT.

Abstract
A motorcycle audio system is provided with circuitry to toggle the helmet mounted microphone of both the driver and the passenger on and off by use of the PTT (push to talk) switches commonly provided for use with a CB radio. Activation of a PTT immediately causes both microphones “on” regardless of their prior state. If the PTT is released during a predetermined short period, the microphones are turned off only if they were on prior to activation of the PTT and remain on only if they were off prior to activation. If the PTT is released after the predetermined period, the microphones remain on only if they were on prior to activation.

5. A motorcycle communication system comprising;
-
(a) at least one PTT, (b) at least one microphone which is activated whenever the PTT is activated. (c) electric circuitry adapted to detect activation and deactivation of the PTT, and (d) said electric circuitry being further adapted to (i) deactivate the microphone when the PTT is deactivated within a period of time after activation of the PTT which is equal to or less than a predetermined short period of time only if the microphone was activated prior to activation of the PTT, and (ii) deactivate the microphone when the PTT is deactivated within a period of time after activation of the PTT which is greater than said short period of time only if the microphone was deactivated prior to activation of the PTT. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
