Apparatus for communicating receipt of transmitted messages
First Claim
1. In a communication system including a portable unit capable of transmitting a signal, a player unit capable of playing a pre-recorded emergency message, and a CB radio capable of communicating with a listener at a remote CB radio station, an apparatus comprising:
- receiver means for producing a signal in response to receiving a signal from the portable unit;
power supply means, coupled to the receiver means and to the CB radio, for receiving the signal produced by the receiver means, providing power, and activating the CB radio;
interface means, coupled to the power supply means, to the CB radio and to the player unit, for activating the player unit to play the emergency message and the CB radio to transmit the emergency message in response to activation by the power supply means, for deactivating the player unit to stop playing the emergency message and the CB radio to stop transmitting the emergency message during a listening period in response to a selected signal from the player unit, and for receiving an acknowledgement signal representing a replay received by the CB radio from the listener; and
listening circuit means, coupled to the interface means and to the power supply means, for causing the interface means to deactivate the CB radio to stop transmitting the emergency message in response to receipt during the listening period by the interface means of the acknowledgement signal indicating receipt by the listener of the transmitted emergency message.

Abstract
An apparatus is provided for communicating to a transmitter or sender of an emergency message a response indicating that the message was received. The communicating apparatus operates in conjunction with a portable alarm unit carried by the sender, a continuous-loop magnetic tape recorder-player, and a local CB radio (i.e., a CB radio located within the range of the portable alarm unit). In response to a signal from the portable alarm unit, the apparatus activates the communicating recorder-player causing it to play a pre-recorded emergency message and to apply this message, in the form of a message signal, to the local CB radio. The local CB radio transmits the message to a listener at a remote CB radio station. In response to a selected acknowledgement message received from a listener via the local CB radio, the communicating apparatus detects the acknowledgement message and transmits a signal to the portable alarm unit indicating receipt by a listener of the emergency message. The communicating apparatus includes a transceiver, a power supply unit, an interface unit, and a listening circuit.

6. In a communication system including a portable unit capable of transmitting a signal, a player unit capable of playing a pre-recorded emergency message, and a radio capable of communicating with a listener at a remote station, an apparatus comprising:
-
receiver means for receiving a signal from the portable unit; interface means, coupled to the receiver means, to the player unit and to the radio, for causing the emergency message to be transmitted by the radio in response to receipt of the signal from the portable unit by the receiver means, for deactivating the player unit to stop playing the emergency message and the radio to stop transmitting the emergency message in response to a selected signal originating from the player unit, and for receiving an acknowledgement signal representing a reply received by the radio from the listener; and listening circuit means, coupled to the interface means and responsive to receipt of the acknowledgement signal by the interface means, for causing the interface means to deactivate the radio to stop transmitting the emergency message. - View Dependent Claims (7)
