Extravehicular communication system and method
First Claim
1. In combination with a car, a communication system comprising:
- a) a first communicator fixedly connected to the car;
b) a harness fixedly connected to the car and having a first set of contacts;
c) a second communicator having a second set of contacts arranged to engage the first set of contacts when seated in the harness and being movably positionable relative to the car when removed from the harness, the first and second communicators being operable to convey audio messages therebetween over any one of a plurality of channels at any given moment; and
d) a synchronization circuit coupled to the first communicator and coupled to the second communicator through the harness, the synchronization circuit being operative to synchronize the first and second communicators to a common, low-noise channel while the second communicator is absent from the harness.

Abstract
A communication system and methods are disclosed for use with vehicles. The communication system includes a first communicator attached to the car and a second communicator that is selectively mounted to a harness in the car. When the second communicator is disengaged from the harness, the communicators are synchronized to a common operative channel or frequency with low-noise, and are ready to be put in service. One disclosed method provides a simple to use communication system that provides toll-free, local communication between a person within the vehicle and a passenger who has left the vehicle. Another disclosed method permits toll-free, local communication between people in two different vehicles.

7. A method for communicating with a person in a car from a remote location, comprising the steps of:
-
a) providing a car with a first communicator and a harness which are both fixedly connected to the car and providing a second communicator movably positionable relative to the car and selectively enagagable with the harness, the first and second communicators being operable to communicate with each other over any one of a plurality of frequencies at any given moment;
b) synchronizing the frequency at which the first and second communicators communicate while the second communicator is absent from the harness; and
c) automatically activating the first and second communicators at the synchronized frequency while the second communicator is absent from the harness. - View Dependent Claims (8, 9, 10, 11, 12)
