Abstract

A preferred embodiment of the present invention provides an emergency call box that has a cellular transceiver, a controller for controlling the cellular transceiver, and a memory for storing preprogrammed telephone numbers. Additionally, a display and push button selection switches are provided to allow bidirectional communication between the controller and a call box user. The controller presents the user with preprogrammed questions through the display, determines which one of the preprogrammed telephone numbers should be called based on the response received through the selection switches, and places a call to the determined telephone number using the cellular transceiver. In one embodiment, the controller determines whether there is an emergency or non-emergency situation based on the user'"'"'s response, calls one of the preprogrammed telephone numbers if there is an emergency situation, and calls another of the preprogrammed telephone numbers if there is a non-emergency situation. In this way, the emergency call box can screen non-emergency calls and automatically route such calls to a location other than an emergency dispatch center. This removes the non-emergency calls from the call traffic received at the emergency dispatch center so that the emergency dispatch operator need only respond to true emergency situations.

Claims

2. The emergency call box as defined in claim 1, wherein the communication means includes a display for communicating messages to the user and an input means for receiving responses from the user.

3. The emergency call box as defined in claim 2, wherein the input means includes a plurality of push button selection switches.

4. The emergency call box as defined in claim 1,

wherein the controller determines whether there is an emergency or non-emergency situation based on the user'"'"'s response to the preprogrammed message(s),

the controller calls one of the preprogrammed telephone numbers if it determines there is an emergency situation, and

the controller calls another of the preprogrammed telephone numbers if it determines there is a non-emergency situation.

5. The emergency call box as defined in claim 1, wherein the controller determines which language is spoken by the user through the communication means.

6. The emergency call box as defined in claim 1, further comprising a keypad connected to the controller, the controller receiving user input through the keypad and transmitting the received input as data using the transceiver.

7. The emergency call box as defined in claim 6,

wherein the controller determines if the user is hearing or speech-impaired using the communication means, and

the controller calls a specific one of the preprogrammed telephone numbers if the controller determines the user is hearing or speech-impaired or transmits a specific code if the caller is hearing impaired, and

the controller calls another of the preprogrammed telephone numbers or transmits a different code if the controller determines the user is not hearing or speech-impaired.

8. An emergency call box of the type that enables bidirectional radiotelephonic communication between a user and a remote location, said emergency call box comprising:

a display presenting information to the user;

push button selection switches receiving information from the user;

a controller providing output to the display and receiving input from the selection switches;

means for storing a plurality of preprogrammed telephone numbers, the preprogrammed telephone number corresponding to a plurality of remote locations; and

means for storing a plurality of preprogrammed questions,

wherein the controller presents the user with at least one of the preprogrammed questions through the display, receives the user'"'"'s response through the selection switches, and determines which one of the preprogrammed telephone numbers to call based on the user'"'"'s response.

9. The emergency call box as defined in claim 8,

wherein the controller determines whether there is an emergency or non-emergency situation based on the user'"'"'s response,

the controller calls one of the preprogrammed telephone numbers if it determines there is an emergency situation, and

the controller calls another of the preprogrammed telephone numbers if it determines there is a non-emergency situation.

10. The emergency call box as defined in claim 8, wherein the controller determines which language is spoken by the user using the selection switches, and presents information on the display in the language spoken by the user.

11. The emergency call box as defined in claim 8, further comprising a keypad coupled to the controller, the controller receiving user input from the keypad and transmitting the received input as data.

12. The emergency call box as defined in claim 11,

wherein the controller determines if the user is hearing or speech-impaired through the display and selection switches, and

the controller calls one of the preprogrammed telephone numbers if it determines the user is hearing or speech-impaired, and

the controller calls another of the preprogrammed telephone numbers if it determines the user is not hearing or speech-impaired.

13. A method of controlling an emergency call box of the type that enables bidirectional radiotelephonic communication between a user and a remote location, said method comprising the steps of:

questioning a user;

receiving the user'"'"'s response to the questioning;

determining which language is spoken by the user;

determining which one of a plurality of preprogrammed telephone numbers should be called based on the user'"'"'s response determining which one of a plurality of preprogrammed codes should be transmitted based on the user'"'"'s response; and

placing a call to the determined preprogrammed telephone number or transmitting the preprogrammed call.

14. A method of controlling an emergency call box of the type that enables bidirectional radiotelephonic communication between a user and a remote location, said method comprising the steps of:

questioning a user;

receiving the user'"'"'s response to the questioning;

determining which one of a plurality of preprogrammed telephone numbers should be called based on the user'"'"'s response or determining which one of a plurality of preprogrammed codes should be transmitted based on the user'"'"'s response including;

determining if the user is hearing or speech-impaired based on the user'"'"'s response to the questioning;

determining that one of the preprogrammed telephone numbers should be called if it is determined that the user is hearing or speech-impaired; and

determining that another of the preprogrammed telephone numbers should be called if it is determined that the user is not hearing or speech-impaired; and

placing a call to the determined preprogrammed telephone number transmitting the preprogrammed call.

15. A method of controlling an emergency call box of the type that enables bidirectional radiotelephonic communication between a user and a remote location, said method comprising the steps of:

questioning a user;

receiving the user'"'"'s response to the questioning;

determining which one of a plurality of preprogrammed telephone numbers should be called based on the user'"'"'s response or determining which one of a plurality of preprogrammed codes should be transmitted based on the user'"'"'s response including;

determining whether there is an emergency or a non-emergency situation based on the user'"'"'s response to the questioning;

determining if the user is hearing or speech-impaired based on the user'"'"'s response to the questioning;

determining that a first of the preprogrammed telephone numbers, which corresponds to a non-voice communication operator, should be called if it is determined that the user is hearing or speech-impaired;
