## Title
Emergency cellular telephone system

## Abstract

A telephone system includes a user-carried emergency communication system in combination with a cellular telephone. The user-carried handset has a large button on a first face. Pressing the button summons help by automatic connection to the 911 emergency telephone network. It also activates a signaling device mounted on the inside glass surface of a window that illuminates a message that 911 has been called. It may also sound an alarm. A pre-recorded massage may also be sent to the emergency call center. The other face has the functions of a cellular telephone. All elements are within the building, with installation by simply plugging cords into power outlets the same as any cellular phone and mounting the signaling device with suction cups. There are no monthly fees except for the usual cellular phone fee.

## Background
BACKGROUND OF THE INVENTION
The present invention relates generally to a telephone system, and more particularly to a cellular telephone system that provides both conventional cellular telephone operation as well as a special emergency telephone operation. The current emergency service system in operation throughout this country is the 911 emergency service provided by the telephone system. The system has the ability to locate any residence from which a landline telephone call to the 911 number is made. Cellular telephones do not have this feature, although the 911 system may be able to triangulate the call emissions to determine the present location of the caller. Many individuals may find themselves alone in a location that is equipped with only a cellular telephone. If they are incapacitated, they may dial 911 for assistance. They may not be able to tell the 911 operator their exact location when they are at home. Even when a call is successful and responders reach the address given them, they may not be sure of which door leads to the caller, such as in an apartment building. If no one answers, they may be reluctant to break in, and they may leave without rendering any assistance.
Cellular telephones of the prior art have a rechargeable battery that is periodically recharged by a recharging unit connected to a house power outlet.
McMinn et al., in U.S. Pat. No. 4,993,058 issued Feb. 12, 1991 disclose an emergency signaling system that includes a lighted house number and strobe light on the outside of the house connected by wires to a control box within the house, presumably through one or more holes in the building. The control box senses dialing the emergency number and is connected to the phone line and also a power outlet.
Commercial services provide a panic button that is a limited function cellular telephone to be worn by an individual as a pendant. The button is pushed in an emergency. This telephones the service provider who then notifies an emergency system to send help, giving the location to which help is to be sent. There is a considerable monthly charge for this service. It does not solve the problem of no one answering a knock on the door. Most in need of this service are the elderly who may not have the funds for this service, and may need help for any installation beyond simple plug in. If they are renters, they may not be permitted to make changes such as holes through the wall. Even when the responders reach the address given them, they may not be sure of which door leads to the caller, such as in an apartment building. If no one answers, they may be reluctant to break in, and they may leave without rendering any assistance.
SUMMARY OF THE INVENTION
This invention provides both a conventional cellular telephone operating system as well as a special emergency telephone operation along with means for alerting those outside a building that an emergency call has been made from within the building. It requires neither special installation nor monthly expenditure outside of the original cellular telephone service fees. A conventional cellular telephone or handset has one radio frequency connection. The handset contains a rechargeable battery that is periodically recharged in a separate charger connected to a house power outlet. A user in need of emergency help may call the emergency telephone number such as 911 and tell the operator the location of the caller and other information. The above is true of conventional cordless telephones. The handset of the invention has a first broad face with the usual features provided by a cellular telephone. In addition to the usual handset features, this one has a reverse side featuring a large emergency button that calls 911. The handset of this invention also has a second radio connection. It is a short range radio connection to an alerting device that attaches to the inside glass surface of a window with one or more suction cups. The alerting device is connected to an inside house power outlet. When the alerting device receives the short range radio frequency signal from actuation of the emergency button, it emits a light signal to the outside through the window indicating that an emergency call has been made from the premises. It may also provide an audible signal. The alerting device is mounted on the inside glass surface of a window preferably at the front of the premises. This enables the responders to more easily find the caller. The handset is designed to be compact so as to be conveniently carried or worn, for example, as a pendant around the neck or clipped to the clothes with the emergency button outermost. When an ordinary call comes in, the user need not rush to a phone, because it is at hand. This avoids injury from rushing to answer a call. In the event of a fall or emergency anywhere in the residence, the user need not travel to get help. The alerting device may be provided with another feature. When the alerting device receives a signal indicating that the emergency button has been actuated, it may send a signal back to the handset. This signal may actuate a recorded message that is sent out on the cellular network indicating the request for help, the location of the device, and other information such as, “I have diabetes. My neighbor at apartment 203 has a key”. If the user is unable to speak, the recorded message will suffice. Since this message will not be given when the handset is beyond the range of the short range radio signal and the premises, there is no danger of confusing the responders by having them go to a vacant location. The recharge station is best provided at the bedside to provide the handset at hand while in bed, and to ensure regular recharging.
These and other objects and advantages will appear from the following description of an illustrative embodiment of the present invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
This invention now will be described more fully hereinafter with reference to the accompanying drawing, in which exemplary embodiments are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth here. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those of ordinary skill in the art. Moreover, all statements herein reciting embodiments of the invention, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future.
Referring now to the drawing FIGS. 1-7, an emergency cellular telephone system 21 of the invention, as shown diagrammatically in FIG. 1, comprises a remote cellular network 10, a handset 1, and a signaling device 6. The handset 1 has a transceiver 25 that communicates with a transceiver 26 in the signaling device by short range radio waves 14 on a bandwidth assigned by the FCC for this purpose. A recharging station 11, has a connection 23 to a house power outlet.
The handset 1 has a first broad face 2 provided with a keypad 3 to enable the handset to perform the calling function of handsets of the prior cellular art through the long range radio waves 9 currently used for cellular communication. A second, opposed broad face 4 is provided with a large, readily accessible emergency call button 5. The button may be recessed or provided with other means to prevent inadvertent actuation, such as, for example, but not limited to, a cover, a time control to only actuate if the button is depressed for a preset time period, and the like. A cancel button 28 may be provided to cancel an emergency call. A microphone 19 and speaker 20 and a talk button 29 may all be available to a user of the second face. A connecting means 13 is provided so that the handset may be worn by the user as a pendant, fastened to the clothing, or with a wrist band with the second face outermost. When a call comes in, the user need only press the talk button to commence a conversation. If the user should fall or encounter some other emergency, they need only press the emergency button to be connected to the 911 operator.
The signaling device 6, as seen in FIG. 1, is best mounted by suction cups on the inside glass surface 8 of a window 7 on the same side of the building as an entryway 27. Device 6 is powered by power connector 23 to house power. It remains inactive until activated by the generation of a call to the emergency number. The call to the emergency number will cause a signal 14 to be emitted from the handset 1 that will be received by transceiver 26 in the signaling device 6 that will cause the message “calling 911” to be illuminated at lighting boxes 17, Also strobe lights 17′ may be operated to get the attention of responders, if desired. The device may also be provided with a sound generator 18 that is pressed against the glass to attract attention. Sound generator 18 may be pressed against the glass by spring 30 so that the sound will be better heard outside, and sound absorbing materials 31 may reduce the sound indoors. The cancel button 28 on the handset may be used to inactivate the signaling device. A pre recorded message facility 16 may be mounted in the signaling device for actuation when a 911 call is made to deliver a prerecorded massage to the responder via the handset. If the person making the emergency call is not on the premises, the short range signal 14 will not reach the signaling device 6. The device 6 will not activate, and the pre-recorded message will not be sent. This prevents misdirecting responders, and others nearby. A recharging station 11 has a connection 23 to a house power outlet. The station 11 connects to the rechargeable handset battery 12. The recharging station is adapted to present the second face 4 with the emergency button 5 exposed while charging so that it may be positioned at the bedside for easy access while the user is in bed. This also ensures that the battery will be recharged daily before being worn.
Many phones also include a visual display for caller ID use. Some also include message recording features. One or all of these additional features may optionally be incorporated into the instant invention. They may be omitted in the interest of making the handset more easily carried. While I have shown and described the preferred embodiments of my invention, it will be understood that the invention may be embodied otherwise than as herein specifically illustrated or described, and that certain changes in form and arrangement of parts and the specific manner of practicing the invention may be made within the underlying idea or principles of the invention.
