Abstract

A system and method determines the location of a resident during an emergency within a monitored area having a plurality of residences such as when a wireless emergency call transmitter is activated. In accordance with one aspect, a wireless emergency call transmitter is positioned within the area and includes a radio frequency (RF) transmitter that is resident activated during an emergency for transmitting an RF signal containing a transmitter code indicating the identity of the emergency call transmitter. The emergency call transmitter includes a receiver section that receives an infrared or acoustic signal containing a location code identifying a room or other location. This signal is received from a location monitor that had received the RF signal from the emergency call transmitter. In response to receiving the infrared or acoustic signal, the emergency call transmitter transmits an RF signal containing the location code.

Claims

1. A system for determining the location of a resident within a monitored area having a plurality of residences during an emergency, comprising:

a wireless emergency call transmitter positioned within a monitored area, and including a radio frequency (RF) transmitter that is resident activated during an emergency for transmitting an RF signal containing a transmitter code indicating the identity of the emergency call transmitter, said emergency call transmitter further including a receiver section that receives an infrared or acoustic signal containing a location code identifying a location, and in response, transmitting an RF signal containing the location code; and

a location monitor positioned within an area containing the emergency call transmitter and storing a location code identifying the area of the location monitor, the location monitor including an RF receiver for receiving the RF signal from the emergency call transmitter, and a transmitter that in response to the location monitor receiving the RF signal from the emergency call transmitter, transmits an infrared or acoustic signal containing the location code to the emergency call transmitter for subsequent processing to determine the location of the wireless emergency call transmitter.

2. A system according to claim 1, wherein the emergency call transmitter comprises a pendent adapted to be worn by a resident.

3. A system according to claim 2, wherein the pendent includes a resident actuated help switch that initiates the transmitter.

4. A system according to claim 1, which further comprises a processor that receives the RF signal containing the location code and transmitter code processes the RF signal to determine the location of the emergency call transmitter.

5. A system according to claim 1, wherein the transmitter of the location monitor comprises an ultrasonic transducer for emitting an ultrasonic signal that carries the location code.

6. A system according to claim 5, wherein the emergency call transmitter includes a microphone for receiving the ultrasonic signal emitted from the location monitor.

7. A system according to claim 1, wherein the transmitter of the location monitor comprises an infrared transmitter for transmitting an infrared signal that carries the location code to the emergency call transmitter.

8. A system according to claim 1, wherein the emergency call transmitter includes a sensor for receiving the infrared signal.

9. A system for determining the location of a resident within a monitored area having a plurality of residences during an emergency, comprising:

a wireless emergency call transmitter positioned within a monitored area, and including a radio frequency (RF) transmitter that is resident activated during an emergency for transmitting an RF signal containing a transmitter code indicating the identity of the emergency call transmitter, and an infrared or acoustic transmitter that transmits an infrared or acoustic signal;

a location monitor positioned within an area containing the emergency call transmitter and storing a location code identifying the area of the location monitor, the location monitor including a receiver for receiving the infrared or acoustic signal from the emergency call transmitter, and an RF transmitter that in response transmits an RF signal containing the location code;

at least one emergency call receiver that receives the RF signals from the emergency call transmitter and location monitor; and

a processor operative with the emergency call receiver that processes the RF signals and determines the room location of the emergency call transmitter.

10. A system according to claim 9, wherein the emergency call transmitter comprises a pendent adapted to be worn by a resident.

11. A system according to claim 10, wherein the pendent includes a resident actuated help switch that initiates the transmitter.

12. A method for determining the location of a resident that has activated a wireless emergency call transmitter that is located in a monitored area having a plurality of residences, which comprises:

transmitting from the emergency call transmitter to an RF receiver and associated processor a radio frequency (RF) signal containing a transmitter code indicating the identity of the emergency call transmitter that had been resident activated;

receiving the RF signal within a location monitor that is located in an area containing the emergency call transmitter;

transmitting from the location monitor to the emergency call transmitter an infrared or acoustic signal containing a location code indicating the area of the location monitor; and

transmitting an RF signal containing the location code from the emergency call transmitter to an RF receiver and processor that processes the RF signals and determines the identity and location of the emergency call transmitter.

13. A method according to claim 12, which further comprises emitting an ultrasonic signal as the acoustic signal.

14. A method according to claim 12, which further comprises displaying the location of the emergency call transmitter on a display at a caretaker facility.

15. A method for determining the location of a resident that has activated a wireless emergency call transmitter that is located in a monitored area having a plurality of residences, which comprises:

transmitting from the emergency call transmitter to an emergency call receiver an RF signal containing a transmitter code indicating the identity of the emergency call transmitter while also transmitting an acoustic signal;

receiving the acoustic signal within a location monitor that is located in an area containing the emergency call transmitter; and

transmitting from the location monitor to an emergency call receiver a wireless signal containing a location code indicating the area in the residence of the location monitor.

16. A method according to claim 15, which further comprises processing the RF signals containing the transmitter code and location code within a processor associated with the emergency call receiver to determine the location of the emergency call transmitter.

17. A method according to claim 15, which further comprises displaying the location of the emergency call transmitter on a display at a caretaker facility.

18. A method according to claim 15, which further comprises emitting an audible tone from the emergency call transmitter.
