## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Application No. 61/416,504, filed on Nov. 23, 2010, which is herein incorporated by reference in its entirety.


TECHNICAL FIELD
The present invention relates generally to mobile communication devices. More particularly, the present invention relates to a dual-mode vehicle mobile phone disabler.
BACKGROUND
Mobile phones are widely used for communication and entertainment. Mobile phone use while driving is common, but frequently dangerous. Due to the number of accidents that are related to mobile phone use while driving, some jurisdictions have made the use of a mobile phone while driving illegal. Others have enacted laws to ban handheld mobile phone use, but allow use of a headset. In some cases restrictions are only directed to minors or those who are newly qualified license holders.
Unfortunately though, penalties resulting from violation of such laws are relatively lax and do not serve as a sufficient deterrent. Also, inadequate law enforcement, partially resulting from a recent economic downturn and continuing terrorist threat, contributes to violations of such laws. Furthermore, when operating a vehicle, many individuals hide the mobile phone when a law enforcement officer is nearby and resume its use when the law enforcement officer is away.
To reduce the number of accidents that are related to mobile phone use while driving, some mobile phone makers have incorporated voice activated features into the mobile phones. However, the software enabling the voice activated features is inadequate. Also, the voice activated features often cause a vehicle operator, especially a new driver or a minor learning how to drive, to become distracted during vehicle operation. Moreover, new drivers or minors learning how to drive often do not have the skills required to operate a vehicle proficiently on top of the complexities of operating a mobile communication device.
Similarly, driving while using a headset is often not safer than using a mobile phone as the increased cognitive workload involved in holding a conversation, not the use of hands, causes the increased risk. Hence, many individuals still operate vehicles, while using a mobile phone, thus endangering themselves and others.
Although some methods of reducing mobile phone use within a vehicle have been developed, the methods suffer from various drawbacks. For example, some signal scrambling devices are somewhat helpful in reducing mobile calls during vehicle operation, but illegal according to the Federal Communications Commission (FCC). Also, signal scramblers are inadequate in effectively reducing the use of mobile phones for entertainment purposes, such as video games.
Accordingly, more efficient ways of dealing with at least the foregoing disadvantages are desired.
BRIEF SUMMARY
It is an object of an example embodiment of the present invention to provide a system, which effectively disables at least one communication functionality of a mobile phone before operating a vehicle. Accordingly, an example embodiment of the present invention is a dual-mode vehicle mobile phone disabler installed in a vehicle. The disabler enables a vehicle ignition system upon confirming that the mobile phone is not in use and at least one communication functionality except for emergency functionality is self-disabled by the mobile phone.
It is another object of another example embodiment of the present invention to provide a system, which effectively maintains disabled at least one communication functionality of a mobile phone during operation of a vehicle. Accordingly, an example embodiment of the present invention is a dual-mode vehicle mobile phone disabler installed in the vehicle. The disabler maintains disabled at least one communication functionality of the mobile phone during operation of the vehicle by periodically sending a continue disable signal to the mobile phone. Upon receipt of the continue disable signal, the mobile phone remains disabled except for emergency use until the vehicle is turned off and then the disabler ceases to transmit the continue disable signal to the mobile phone. In response, the mobile phone self-enables the least one disabled communication functionality.
An example embodiment of the present invention is a system for effectively preventing operation of a land vehicle having an interior when at least one communication functionality of a mobile phone is in use within the interior. The system includes a dual-mode mobile phone disabler and a power source. The dual-mode mobile phone disabler includes a processor powered by the power source and an antenna operably connected to the processor. In a first mode, prior to the vehicle being turned on, the processor, via the antenna, searches for and detects a communication signal from the mobile phone within the interior of the vehicle when the at least one communication functionality of the mobile phone is in use. In response to the detected communication signal, the processor prevents the vehicle from being turned on until the processor, via the antenna, detects no use of the at least one communication functionality of the mobile phone. The at least one communication functionality includes communication with a cell site. The communication signal is indicative of use of the at least one communication functionality. In a second mode, after the vehicle has been turned on, the processor, via the antenna, periodically communicates with the mobile phone within the interior of the vehicle to keep disabled the at least one communication functionality of the mobile phone. Upon the vehicle being turned off, the antenna ceases to communicate.
Another example embodiment of the present invention is a dual-mode land vehicle mobile phone disabler for use within an interior of a land vehicle having an ignition switch with a first position and a second position. The disabler includes an antenna and a processor operably connected to the antenna. When the ignition switch is set to the first position, the processor via the antenna searches for a communication link between a mobile phone within the interior and a cell site. The disabler also includes a means for immediately disabling operation of the ignition switch when the communication link is detected. The disabler further includes a means for continuously sending a disable signal to the mobile phone within the interior when the ignition switch is set to the first position and ceasing the sending of the disable signal when the ignition switch is set to the second position. The disable signal prevents the mobile phone within the interior from establishing the link with the site.
Yet another example embodiment of the present invention is a method for effectively preventing operation of a land vehicle having an interior when a mobile phone within the interior is in communication with a cell site. The method includes prior to the vehicle being turned on, searching for a communication link between the phone within the interior and the cell site. The method also includes detecting the link and preventing the vehicle from being turned on until the link is severed. The method further includes allowing the vehicle to be turned on when the link is severed and periodically communicating with the phone within the interior to prevent the phone within the interior from establishing the link with the site. The method even further includes ceasing communicating with the phone within the interior when the vehicle is turned off.
To the accomplishment of at least one of the above and related objects, the present invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact, however, that the drawings are illustrative only. Variations are contemplated as being part of the invention, limited only by the scope of the claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, which show various embodiments. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure is thorough, complete and fully conveys the scope of the invention to those skilled in the art.
FIG. 1 is a schematic system diagram of an example embodiment of a dual-mode automotive mobile phone disabler system according to the present invention. An automobile includes a circuit 100. The automobile is operated by an operator.
Circuit 100 includes an automobile battery 110, an automobile ignition switch 130, a mobile phone disabler 140 and an automobile ignition system 147. A mobile phone 155 is within operational proximity of mobile phone disabler 140. Mobile phone 155 can include a chip which communicates with mobile phone disabler 140 in order to determine if at least one communication functionality of mobile phone 155 is currently being used.
Battery 110 includes a negative terminal 115 and a positive terminal 117. Although battery 110 has a voltage of twelve volts, battery 110 can have other voltages. A connection 120 connects positive terminal 117 and ignition switch 130.
Ignition switch 130 is actuated by the operator. Ignition switch 130 has five settings: an accessory powering setting 132, an ignition lock setting 134, an off setting 136, a run setting 138 and a start setting 139.
Accessory powering setting 132 switches on power to many auto accessories, such as radio or power windows.
Ignition lock setting 134 locks ignition switch 130.
Off setting 136 keeps ignition switch 130 off.
Run setting 138 keeps an automobile engine running after the automobile is started.
Start setting 139 powers an electric starter to start the automobile's engine.
A connection 148 connects mobile phone disabler 140 to connection 120. Mobile phone disabler 140 continuously receives power via connection 148.
A connection 149 connects ignition switch 130 at setting 138 to mobile phone disabler 140. Alternatively, connection 149 connects ignition switch 130 at other settings, such as 132, 134, 136 or 139.
Mobile phone disabler 140 is connected to automobile ignition system 147 and an automobile body/chassis ground 143. Mobile phone disabler 140 includes an antenna 145, which actively listens for signals emitted from mobile phone 155.
In an example mode of operation, within operational proximity of mobile phone disabler 140, mobile phone 155 is not in use and emits a signal, such as a connection to a cell site signal. In a first mode, via antenna 145, mobile phone disabler 140 detects the signal, determines that mobile phone 155 is not currently used for a phone call, communicates with mobile phone 155 and disables at least one communication functionality of mobile phone 155, such as making or receiving phone calls, emails, Internet browsing or text messaging. However, emergency communications are not disabled, such as making a phone call to emergency response service (911). Upon disabling of a communication functionality, mobile phone disabler 140 allows the operator to start the automobile via automobile ignition system 147.
In a second mode, if mobile phone disabler 140 determines that mobile phone 155 is in use, such as during a phone call, mobile phone 155 is not automatically disabled by mobile phone disabler 140. Rather, mobile phone disabler 140 instead prevents the operator from starting the automobile by disabling automobile ignition system 147 during the phone call. Via antenna 145, mobile phone disabler 140 periodically scans the signals emitted from mobile phone 155 to determine when the phone call ends. When mobile phone disabler 140 determines that the phone call ended, mobile phone disabler 140 communicates with mobile phone 155, disables at least one communication functionality of mobile phone 155 and enables the operator to start the automobile via automobile ignition system 147. However, emergency communications are not disabled, such as making a phone call to emergency response service (911).
In another example embodiment, mobile phone disabler 140 disables at least one gaming or entertainment functionality of mobile phone 155, such as solitaire or playing a video file.
In yet another example embodiment, at least one communication functionality of the mobile phone includes responsive/answering communications, such as phone calls/texting/emails between friends or organizations, thereby excluding communications associated with a global positioning system (GPS). Thus, mobile phone disabler 140 only monitors cell site communications, such as phone calls, texting, Internet browsing or emailing.
In yet even another example embodiment, at least one communication functionality of the mobile phone includes direct inter mobile phone communications between a plurality of mobile phones within the vehicle.
