Enhancement of a personal emergency response system
First Claim
1. A personal emergency response system which includes at least one subscriber station coupled via a telephonic communication link to a central monitoring station, comprising:
- dedicated emergency communication means for radio frequency transmission of information signals over at least one predetermined frequency;
subscriber unit means disposed within the at least one subscriber station and normally operative in response to a predetermined condition for transmitting messages over the telephonic communication link to the central monitoring station;
emergency transceiver means having a receiver and a transmitter and normally operative as a radio receiver but not as a transmitter;
means coupled to the emergency transceiver means for monitoring the at least one predetermined frequency for information signals transmitted thereon and operative in response for reception of the information signals for broadcasting the information signals within the at least one subscriber station via the radio receiver and for transmitting a signal back to the dedicated emergency communications means via the transmitter.

Abstract
An apparatus and method for use in combination with a personal emergency response system. Typical systems establish a telephone communication link between a subscriber station and a central monitoring station in order to monitor the needs of elderly and/or infirm persons confined to their residences. In the normal operation of a system, a user located at a subscriber station activates a subscriber unit which transmits an alert signal via a telephone communication link to a central monitoring station which dispatches aid to the subscriber station. The system of the present invention incorporates an ancillary radio frequency receiver or transceiver subsystem as an alternate communication link in the event that telephone service becomes disabled. The ancillary radio receiver provides the user with the ability to receive radio frequency transmissions which inform the user that telephone lines have become disabled. In a second embodiment, a supplemental radio transceiver subsystem is implemented into the system to provide the user with the capability to transmit as well as receive information in the event that normal telephone channels are incapacitated.

9. An apparatus for providing radio frequency communication in a personal emergency response system, said personal emergency response system including at least one subscriber station coupled via a telephonic communication link to a central monitoring station, wherein said apparatus for providing radio frequency communication comprises:
-
a dedicated emergency communication station capable of transmitting a warning signal over at least one predetermined first radio frequency and capable of transmitting emergency information over a predetermined second radio frequency; subscriber unit means disposed within the at least one subscriber station and normally operative in response to a predetermined condition for transmitting messages over the telephonic communication link to the central monitoring station; emergency radio means having a speaker and normally in an off state; and means coupled tot he emergency radio means for monitoring said at least one predetermined first radio frequency for said warning signal and operative in response to reception of the warning signal for causing the emergency radio means to assume an on state and to receive emergency information on said predetermined second radio frequency and for broadcasting in the on state the emergency information signals within the at least one subscriber station via the speaker of the emergency radio means. - View Dependent Claims (10, 11, 12, 13, 14)
