<p>: An apparatus for use with or integrally formed of a telephone instrument, where the telephone instrument is thus functional to enable concurrent use and non-use of related equipment. The apparatus has a faceset means formed of a transmitterreceiver unit worn along a user's face for positioning the transmitter in proximity to a user's mouth and the receiver in proximity to said user's ear. A module housing the electrical circuitry controls incoming and outgoing electrical signals to the telephone instrument and transfers these signals between the faceset and the telephone instrument. Hence, the user is able to meploy the faceset during a telephone conversation in a hands free manner, A mechanical linkage is formed of the module and serves to actuate the on-off switch of the telephone instrument which is placed in proximity to the module and simultaneously actuating on-off switches in the module to thereby control operation of the faceset and telephone related equipment.</p> |
