CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Application No. 61/153,497, filed Feb. 18, 2009, which is hereby incorporated by reference in its entirety.


BACKGROUND OF THE INVENTION
The subject matter described herein relates generally to emergency cellular phone communication, and more specifically, to methods, apparatus, and systems for automatic initiation of an emergency cellular phone function.
Subscription services are presently available that embed a cellular communication device within a vehicle, for example, an automobile. In other words, these embedded cellular communication devices are part of the automobile. The cellular communication device may include a speaker and a microphone. The cellular communication device may also include global positioning capabilities, for example, a global positioning system (GPS). Through use of the GPS, the cellular communication device is able to communicate the location of the vehicle to an interested party. This is especially useful in a case of an emergency.
The microphone of the cellular communication device may be used to operate the cellular communication device through the use of voice commands. The cellular communication device may include an input, for example a button, that when pressed is configured to direct the cellular communication device to contact a centralized human operator who is able to assist the operator of the vehicle. Some cellular communication devices are coupled to sensors in the automobile and configured to automatically contact the centralized human operator in certain predefined circumstances. For example, upon deployment of an automobile's airbag(s), the cellular communication device may be configured to contact the centralized human operator. The centralized human operator can communicate with the operator of the vehicle using the speaker and the microphone and determine if the situation warrants contacting emergency services, such as police, fire, and/or ambulance services. Other cellular communication devices include an emergency contact input device, for example, a button, that when pressed, will automatically summons emergency services.
Typically, to enroll in a subscription service, a driver must own an automobile that includes the embedded cellular communication device, and also pay a recurring fee, for example, a monthly or yearly subscription fee. This subscription fee is dedicated solely to cellular communication using the automobile's cellular communication device and not, for example, to a home phone or personal cellular phone. A driver who is enrolled in a personal cellular phone contract has to also enroll in the separate, automotive cellular subscription service. Also, access to automotive cellular subscription services may be limited due to exclusive contracts between providers of subscription services and specific automobile manufacturers. For example, the OnStar® subscription service (OnStar is a registered trademark of OnStar, LLC) is exclusively available in automobiles manufactured by or for General Motors Corporation. For some automobiles, there are no automotive cellular subscription services available. Furthermore, typically, automotive cellular subscription services may also be limited to locations where the subscription service provides cellular coverage. Moreover, automotive cellular communication devices, since embedded within the vehicle, require that the vehicle's battery be connected to the cellular communication device and provide enough electricity to power the device.

DETAILED DESCRIPTION OF THE INVENTION
The methods, apparatus, and systems described herein provide automatic initiation of a cellular phone emergency function upon deployment of a vehicle's airbag. Technical effects of the methods, apparatus, and systems described herein include at least one of: (a) receiving, from a vehicle sensor, an airbag deployment signal at an emergency signal assembly; and (b) transmitting the airbag deployment signal from the emergency signal assembly to a cellular phone. Technical effects of the methods, apparatus, and systems described herein may also include at least one of: (a) receiving, at a cellular phone, an airbag deployment signal from an emergency signal assembly; and (b) initiating at least one preprogrammed cellular phone emergency function in response to the airbag deployment signal.
FIG. 1 is a block diagram illustrating an exemplary emergency notification system 100. System 100 is configured to be positioned within a vehicle, for example, but not limited to, an automobile, a watercraft, an aircraft, a locomotive, and or any other form of transportation that would allow system 100 to function as described herein. In the exemplary embodiment, system 100 includes an airbag deployment system 102, an emergency signal assembly 104, and a cellular phone 106. Airbag deployment system 102, emergency signal assembly 104, and cellular phone 106 may be physically coupled by a conductor, for example, a wire, or may be communicatively coupled using wireless technology, for example, but not limited to, Bluetooth® technology (Bluetooth is a trademark of Bluetooth SIG, Inc. of Bellevue, Wash., U.S.A.). System 100 facilitates automatic initiation of at least one preprogrammed emergency function of cellular phone 106.
In the exemplary embodiment, airbag deployment system 102 includes at least one sensor 108 and at least one airbag 110. Although described herein as including a single airbag 110, system 102 may include multiple airbags 110. System 100 is configured to facilitate automatic initiation of at least one preprogrammed emergency function of cellular phone 106 upon deployment of one or more of airbags 110. Sensor 108 measures conditions that may indicate that the vehicle is involved in a situation that would warrant contacting a provider of emergency services, for example, a vehicle impact, collision, or other type of accident that causes a rapid deceleration of the vehicle. Sensor 108 may include an accelerometer configured to measure a deceleration of the vehicle and/or an orientation of the vehicle. If the deceleration indicates a rapid deceleration, sensor 108 generates an emergency indication signal 112 and sends emergency indication signal 112 to airbag 110, which deploys upon receipt of emergency indication signal 112. Sensor 108 may also measure changes in environmental conditions, for example, but not limited to changes in air pressure and changes in humidity level. Such environmental conditions may provide an indication that the vehicle is involved in an emergency situation. Airbag 110 is a passive vehicle safety device that evenly slows the forward motion of a vehicle passenger during a vehicle crash. Airbag 110 is included within the vehicle to reduce injuries to vehicle occupants.
In the exemplary embodiment, emergency signal assembly 104 includes an emergency communication apparatus (shown in FIG. 2) and a vehicle accessory power receptacle (shown in FIG. 2). The emergency signal assembly 104 receives an airbag deployment signal 120 from airbag deployment system 102. Airbag deployment signal 120 is at least one of a signal that corresponds to a deployed airbag and a signal sent to the airbag to deploy the airbag (e.g., emergency indication signal 112). As described above, sensor 108 generates emergency indication signal 112, which may also be transmitted to emergency signal assembly 104 as airbag deployment signal 120. Additionally, or alternatively, an airbag deployment sensor 130 may generate airbag deployment signal 120 once airbag deployment sensor 130 detects that airbag 110 has deployed. Furthermore, airbag deployment signal 120 may include any other suitable signal generated to initiate deployment of airbag 110 and/or to indicate that airbag 110 has been deployed.
In the exemplary embodiment, emergency signal assembly 104 transmits airbag deployment signal 120 to cellular phone 106. Cellular phone 106 comprises a personal cellular phone, a smart phone, and/or any other cellular communication device that allows system 100 to function as described herein. Typically, cellular phone 106 includes a memory device 142, a transceiver 144, an input device 146, an output device 148, a wireless communication device 150, a power/data port 152, and a global positioning system (GPS) device 154, all coupled to a cellular phone processor 156. The term processor, as used herein, refers to central processing units, microprocessors, microcontrollers, reduced instruction set circuits (RISC), application specific integrated circuits (ASIC), logic circuits, and any other circuit or processor capable of executing the functions described herein. Input device 146 may include, but is not limited to, a microphone, a keypad, and a digital camera. Output device 148 may include, but is not limited to, a speaker and a display screen. Wireless communication device 150 may include, but is not limited to, a radio frequency identification (RFID) device, a Bluetooth® compatible device, a near-field communication device, or any other suitable wireless communication device that allows system 100 to function as described herein. Typically, power/data port 152 is manufacturer-specific, and is operable to connect a battery charger to cellular phone 106 and also to transmit/receive data and/or phone control signals from an external source. In the exemplary embodiment, power/data port 152 includes a dedicated conductor that is part of a circuit that includes airbag deployment system 102, emergency signal assembly 104, and cellular phone 106. The dedicated conductor is configured to receive airbag deployment signal 120 and to activate the at least one preprogrammed emergency function of cellular phone 106.
In the exemplary embodiment, cellular phone 106 receives airbag deployment signal 120 and initiates at least one emergency function of cellular phone 106. More specifically, cellular phone 106 receives airbag deployment signal 120 at least one of wireless communication device 150 and power/data port 152. Emergency functions are preprogrammed functions stored, for example, in memory device 142. Emergency functions may include, but are not limited to, initiating a phone call to an emergency service provider, initiating a phone call to a stored emergency contact, recording audio using the cellular phone, and/or recording images using the cellular phone. Emergency functions may also include sending a location, for example, GPS coordinates from GPS device 154, to the emergency service provider and/or the emergency contact. The emergency service provider may include a fire department, a police department, and/or a hospital, and is typically contacted by dialing 9-1-1. The emergency contact may include a third party whose phone number is stored in a predefined emergency contact location within memory device 142.
In the exemplary embodiment, recording audio and/or recording images functions as a type of “black box.” For example, after an aircraft crash, authorities try to retrieve the black box from the aircraft to give them the last information of what was happening to the aircraft during the last minutes of flight. Many automobiles also include a black box that can provide authorities with data corresponding to events prior to an accident. Using system 100, cellular phone 106 may additionally record images and sounds of what occurs directly after an accident. Valuable information may be provided to the authorities to help in the process of finding out what happened and who was responsible. For example, upon receipt of airbag deployment signal 120, cellular phone 106 discontinues any processes currently being performed, places a call to 9-1-1, and records sounds, pictures, and/or video. More specifically, cellular phone 106 may take pictures periodically, for example, every two to five seconds, or record video. The audio may be recorded for a predefined time period after receipt of airbag deployment signal 120. For example, audio may be recorded for approximately one to two minutes, or until a connection with a 9-1-1 operator is accomplished, because 9-1-1 calls are recorded. After cellular phone 106 is connected to a 9-1-1 operator, the operator will be able to pinpoint the location of cellular phone 106 using GPS device 154 in cellular phone 106. Furthermore, cellular phone 106 may also call anyone on an emergency call list stored in memory device 142 to notify them of the accident and tell them the location of the vehicle.
FIG. 2 is a block diagram illustrating an exemplary embodiment of emergency notification system 100 shown in FIG. 1. FIG. 3 is a side view of an exemplary embodiment of a cellular phone emergency communication apparatus 158, also referred to herein as an emergency communication accessory, which may be included within system 100. FIG. 4 is a top view of the emergency communication apparatus 158 shown in FIG. 3. In the exemplary embodiment, emergency communication apparatus 158 includes a body 160 and a handle 162. In the exemplary embodiment, airbag deployment system 102 includes airbag 110, sensor 108, and an electrical duplication device 164. Electrical duplication device 164 receives emergency indication signal 112 from sensor 108 and transmits emergency indication signal 112 to both airbag 110 and emergency signal assembly 104. As described above, emergency indication signal 112 is an example of airbag deployment signal 120.
In the exemplary embodiment, emergency signal assembly 104 includes a one-way electrical device 170 and a vehicle accessory power receptacle 172. Receptacle 172 is configured to receive emergency communication apparatus 158. More specifically, receptacle 172 is configured to receive body 160 of emergency communication apparatus 158. In some embodiments, receptacle 172 is coupled to airbag deployment system 102 through a vehicle fuse box 174 and through one-way electrical device 170. Furthermore, in the exemplary embodiment, receptacle 172 is a vehicle accessory power source which may be also used as, or commonly referred to as a cigarette lighter receptacle. Receptacle 172 may also include any other type of auxiliary plug-in included within a vehicle. Typically, receptacle 172 provides access to twelve volt direct-current power (12V DC), for example, for powering electric devices such as a GPS device, a laptop computer, a spotlight, and/or cellular phone 106. System 100 is shown as including one receptacle 172, however, system 100, may include any number of receptacles. For example, if a vehicle includes multiple receptacles 172, each of the receptacles is included within system 100. More specifically, in examples where system 100 includes multiple receptacles 172, each receptacle 172 is coupled to airbag deployment system 102, to ensure that airbag deployment signal 120 is received by emergency communication apparatus 158, independent of which receptacle 172 emergency communication apparatus 158 is coupled to.
In the exemplary embodiment, emergency communication apparatus 158 is configured to couple cellular phone 106 to receptacle 172 of emergency signal assembly 104. For example, emergency communication apparatus 158 may include a conductor 176 and a plug 178. Conductor 176 may include a wiring harness, which includes a plurality of individual conductors insulated from one another, coupled to plug 178. Plug 178 may be configured to mate with power/data port 152 of cellular phone 106. For example, plug 178 may include a flat-type plug, a straight-type plug, or any suitable type of plug and/or plug-in “tip” provided by a manufacturer of cellular phone 106. Furthermore, handle 162 may be any suitable shape, for example, but not limited to, round, triangular, rectangular, square, or “T” shaped, that allows emergency communication apparatus 158 to function as described herein. In contrast to a typical cellular phone charging accessory, emergency communication apparatus 158 includes two negative ground posts 180 and 182 and two signal receiving posts 184 and 186. Negative ground posts 180 and 182 facilitate charging a battery of cellular phone 106. Signal receiving posts 184 and 186 receive, via corresponding conductors positioned within receptacle 172, airbag deployment signal 120 from airbag deployment system 102. Vehicle fuse box 174 facilitates reducing accidental sparks or overheating when a connection is made between receptacle 172 and emergency communication apparatus 158.
In the exemplary embodiment, airbag deployment signal 120 is received on signal receiving posts 184 and 186 and transmitted to cellular phone 106 through conductor 176 and plug 178. For example, conductor 176 may include a dedicated conductor coupled directly to a dedicated location on plug 178. The dedicated conductor transmits airbag deployment signal 120 to cellular phone 106. The dedicated location on plug 178 connects with a dedicated receptacle inside cellular phone 106 once its connected together to complete a circuit for airbag deployment signal 120 to be received from airbag deployment system 102 and to initiate the at least one preprogrammed emergency function of cellular phone 106.
As described above, emergency communication apparatus 158 includes signal receiving posts 184 and 186 that receive airbag deployment signal 120 via corresponding conductors positioned within receptacle 172. In the exemplary embodiment, in addition to a positive feed conductor 200 and a negative feed conductor 210, which are included in typical cigarette lighter and/or accessory power receptacles, receptacle 172 also includes an airbag signal feed conductor 220. When emergency communication apparatus 158 is positioned within receptacle 172, airbag signal feed conductor 220 is electrically coupled to at least one of signal receiving posts 184 and 186. In the exemplary embodiment, one-way electrical device 170 facilitates preventing an accidental airbag deployment should a device having a positive charge be plugged into receptacle 172 and/or plug 178 of emergency communication apparatus 158. In some embodiments, airbag deployment signal 120 passes through vehicle fuse box 174. For example, when airbag deployment signal 120 is received at signal receiving post 184 and/or 186, positive feed conductor 200 and negative feed conductor 210 within receptacle 172, and/or negative ground posts 180 and 182 within emergency communication apparatus 158, may connect, causing a fuse within vehicle fuse box 174 to blow, which typically causes illumination of a “check airbag” light on a vehicle dashboard. However, the blown fuse and illuminated “check airbag” light occur after airbag deployment signal 120 has been delivered from the connection on signal receiving posts 184 and 186 to cellular phone 106, which allows initiation of the preprogrammed emergency function of cellular phone 106.
As described above, there are various types of sensors 108 that may be included within a vehicle. The various types of sensors 108 generate different types of emergency indication signals 112. In the exemplary embodiment, electrical duplication device 164 is configured to split and/or duplicate a signal generated by sensor 108. In an exemplary embodiment, electrical duplication device 164 delivers emergency indication signal 112 to airbag 110 and to emergency signal assembly 104. In an alternative embodiment, electrical duplication device 164 delivers emergency indication signal 112 to airbag 110, generates airbag deployment signal 120, and delivers airbag deployment signal 120 to emergency signal assembly 104. In other words, electrical duplication device 164 may be configured to generate airbag deployment signal 120 from emergency indication signal 112 and/or generate airbag deployment signal 120 upon receipt of emergency indication signal 112. Airbag deployment signal 120 may be substantially identical to emergency indication signal 112 or emergency indication signal 112 may be modified and/or converted to a signal understood by emergency signal assembly 104.
In the exemplary embodiment, emergency signal assembly 104 also includes a wireless communication device 230. Wireless communication device 230 is configured to communicate with wireless communication device 150 of cellular phone 106. System 100 may include wireless communication device 230 and receptacle 172, wireless communication device 230 without receptacle 172, or receptacle 172 without wireless communication device 230. In at least some examples, wireless communication device 230 is provided as a back-up to receptacle 172. If cellular phone 106 is not coupled to emergency communication apparatus 158, and therefore not coupled to receptacle 172, wireless communication device 230 allows system 100 to function as described herein. For example, if cellular phone 106 is not coupled to receptacle 172, and emergency communication apparatus 158 is not coupled to receptacle 172, cellular phone 106 may still receive airbag deployment signal 120 via communication with wireless communication device 230. Wireless communication device 230 may include, but is not limited to, a radio frequency identification (RFID) device, a Bluetooth® compatible device, a near-field communication device, or any other suitable wireless communication device that allows system 100 to function as described herein.
As described above, airbag deployment signal 120 may be sent to receptacle 172 and/or to wireless communication device 230. Wireless communication device 230 may be pre-installed in some vehicles or may be added as an after-market accessory. In the event that cellular phone 106 is not plugged into emergency communication apparatus 158 and receptacle 172, and airbag 110 is deployed, when connected to the wireless communication device 230, the preprogrammed emergency function of cellular phone 106 may still be activated because cellular phone 106, and more specifically, wireless communication device 150 of cellular phone 106, receives the airbag deployment signal 120 from wireless communication device 230.
In at least some embodiments, handle 162 of emergency communication apparatus 158 may also include a wireless communication device 240. Wireless communication device 240 provides a wireless communication connection between emergency communication apparatus 158 and cellular phone 106. In the exemplary embodiment, wireless communication device 240 is activated after it receives airbag deployment signal 120 from at least one of signal receiving posts 184 and 186. Wireless communication device 240 wirelessly transmits airbag deployment signal 120 until signal 120 is received by cellular phone 106, which activates the preprogrammed emergency function of cellular phone 106. Wireless communication device 240 provides a back-up when emergency communication apparatus 158 is positioned within receptacle 172, but cellular phone 106 is not plugged into emergency communication apparatus 158. For example, wireless communication devices 230 and 240 are configured to communicate with wireless communication device 150 of cellular phone 106. Wireless communication device 150 recognizes airbag deployment signal 120 and signals cellular phone processor 156 to activate the at least one preprogrammed emergency function of cellular phone 106. The wireless signal generated by wireless communication device 240 and/or wireless communication device 230 may transmit over a range from, for example, 10-500 feet so that any cellular phones within that range would initiate an emergency function and authorities would know who was a witness to the accident and/or emergency.
FIG. 5 is a side view of a first alternative embodiment 300 of the vehicle receptacle 172 shown in FIG. 2. FIG. 6 is a side view of a first alternative embodiment 310 of the emergency communication apparatus 158 shown in FIG. 3. FIG. 7 is a top view of emergency communication apparatus 310 shown in FIG. 6. Emergency communication apparatus 310 includes a tab 330, for example, a tab extending radially outward from a surface of emergency communication apparatus 310, or raised from the surface of emergency communication apparatus 310 in any suitable manner that allows system 100 to function as described herein. Receptacle 300 includes a corresponding slot 332 configured to receive tab 330. Airbag signal feed conductor 220 is coupled to, or positioned within, slot 332. Tab 330 receives airbag deployment signal 120 from airbag deployment system 102 and/or from vehicle fuse box 174. Tab 330 and corresponding slot 332 ensure proper alignment of emergency communication apparatus 310 within receptacle 300. Receptacle 300 accepts regular vehicle accessories in the same manner as typical vehicle receptacles accept vehicle accessories. However, there is only one orientation in which emergency communication apparatus 310 can plug into receptacle 300 because of tab 330.
FIG. 8 is a side view of a second alternative embodiment 350 of the vehicle receptacle 172 shown in FIG. 2. FIG. 9 is a side view of a second alternative embodiment 360 of the emergency communication apparatus 158 shown in FIG. 3. FIG. 10 is a top view of emergency communication apparatus 360 shown in FIG. 9. In the exemplary embodiment, emergency communication apparatus 360 includes negative ground posts 180 and 182 and also includes signal receiving posts 370 and 372. In some examples, a first end 374 of negative ground posts 180 and 182 is positioned a distance 380 from a first end 382 of signal receiving posts 370 and 372. For example, in at least one example, distance 380 is within a range of about 1⁄8-3⁄8 of an inch. As described above, negative ground posts 180 and 182 are substantially similar to the negative ground wire posts included in any cellular phone car charger accessory. However, negative ground posts 180 and 182 may be positioned closer to a tip 384 of apparatus 360 than in a typical cellular phone car charger accessory.
In the exemplary embodiment, signal receiving posts 370 and 372 are configured to receive airbag deployment signal 120. Receptacle 350 includes a conducting lip 390 coupled to airbag signal feed conductor 220. Emergency communication apparatus 360 and receptacle 350 are configured such that signal receiving posts 370 and 372 are electrically coupled to conducting lip 390 when emergency communication apparatus 360 is positioned within receptacle 350. Alternatively, contact between signal receiving posts 370 and 372 and airbag signal feed conductor 220 may be made in a first portion 392 of receptacle 350. First portion 392 of receptacle 350 may be electrically coupled, or formed from the same conductor, as conducting lip 390. In at least one example, first portion 392 of receptacle 350 includes conducting lip 390 and approximately 1⁄8-5⁄8 of an inch of receptacle 350, measured from an open end 394 of receptacle 350. First portion 392 is electrically insulated from the rest of receptacle 350 by an insulating band 396 to facilitate preventing contact between signal receiving posts 370 and 372 and negative feed conductor 210 of receptacle 350. Signal receiving posts 370 and 372 may be angled at a 45° angle from a handle side to a body side of apparatus 360, may be a “teepee” type post, and/or may be any other suitable type of post that allows apparatus 360 to function as described herein. A reason for the 45° angle or the “teepee” shape is to prevent signal receiving posts 370 and 372 from making any accidental contact with the negative part of receptacle 350. Insulating band 396 also facilitates maintaining separation between signal receiving posts 370 and 372 and the negatively charged part of receptacle 350.
FIG. 11 is a flow chart 400 an exemplary method 410 for automatically initiating a cellular phone emergency function in response to an airbag deployment within a vehicle. In the exemplary embodiment, method 410 includes monitoring 412 vehicle operation and generating 414 an airbag deployment signal, for example, airbag deployment signal 120 (shown in FIG. 1), upon a measured indication of an occurrence of a predefined event that warrants performance of emergency functions. For example, airbag deployment signal 120 may be generated 414 upon a measured indication of at least one of a predefined impact to the vehicle and/or a measured indication that an airbag has deployed or will be deployed. In the exemplary embodiment, an airbag deployment system, for example, airbag deployment system 102 (shown in FIG. 1) may include at least one sensor, for example, sensor 108 (shown in FIG. 1) and airbag sensor 130 (shown in FIG. 1) that generate airbag deployment signal 120 when an emergency is detected and/or when an airbag, for example, airbag 110 (shown in FIG. 1) is deployed. In the exemplary embodiment, electrical duplication device 164 delivers emergency indication signal 112 (shown in FIG. 1) to airbag 110 and to emergency signal assembly 104. In an alternative embodiment, electrical duplication device 164 delivers emergency indication signal 112 to airbag 110, generates airbag deployment signal 120, and delivers airbag deployment signal 120 to emergency signal assembly 104.
Method 410 also includes receiving 416 airbag deployment signal 120 at an emergency signal assembly, for example, emergency signal assembly 104 (shown in FIG. 2). An automobile sensor, for example, crash sensor 108 and/or airbag sensor 130, generates airbag deployment signal 120 and transmits airbag deployment signal 120 to emergency signal assembly 104. In the exemplary embodiment, emergency signal assembly 104 includes an automotive accessory, for example, emergency communication apparatus 158 (shown in FIG. 2), configured to communicatively couple a cellular phone, for example, cellular phone 106 (shown in FIG. 2), to airbag deployment system 102. Method 410 also includes transmitting 418 airbag deployment signal 120 from emergency signal assembly 104 to cellular phone 106. Transmitting 418 airbag deployment signal 120 from emergency signal assembly 104 to cellular phone 106 may include transmitting airbag deployment signal 120 through a conductor, for example, conductor 176 (shown in FIG. 2). Transmitting 418 airbag deployment signal 120 from emergency signal assembly 104 to cellular phone 106 may include transmitting airbag deployment signal 120 using a wireless communication device, for example, wireless communication device 230 (shown in FIG. 2) and/or wireless communication device 240 (shown in FIG. 2).
In the exemplary embodiment, method 410 also includes initiating 420 at least one preprogrammed cellular phone emergency function in response to airbag deployment signal 120. Initiating 420 at least one preprogrammed cellular phone emergency function may include automatically initiating a phone call to an emergency service provider by accessing a phone number associated with the emergency service provider stored in cellular phone 106.
