Abstract: A system and method for enabling simultaneous communication and affectation of an operational status of a device for use with a sending device that has a line of communication with a receiving device comprising a receiving/transmitting arrangement operably associated with the line of communication between the sending device and the receiving device for receiving sound signals from the sending device while allowing the receiving device simultaneously to receive the sound signals from the sending device, an activated/controlled device, a line of communication between the receiving/transmitting device and the activated/controlled device, and a transducer for transducing sound signals from the sending device to activate and/or control the activated/controlled device.

Abstract: A terminal unit of a mobile communications system for providing a non-numeric annunciation of an incoming mobile communications signal with a terminal unit housing, a mechanism for coupling the terminal unit housing to an incoming mobile communications signal receiver, a normally inactive non-numeric annunciator operably associated with the terminal unit housing, and a mechanism for coupling the non-numeric annunciator to a mobile communications signal receiver. The mobile communications terminal unit may be constructed for use as a personal vibrator of the type used on a human body with a user engaging portion that may comprise a smooth-ended rod, a smooth plug, or a vibratory aperture. The mobile communications terminal unit alternatively may be constructed with an acoustic or a tactile annunciator for practicing a method of transmitting a command signal to a domestic animal.
