Vehicle Alarm System Triggerable Cell Phone Activation Circuit

The present invention relates to alarm systems for vehicles and more particularly to a vehicle alarm system triggerable cell phone activation circuit that includes an activation cable electrically connectable to an alarm output of a vehicle alarm system; a pager mode integrated circuit having a dual tone telephone tone generator and sufficient programmable pager phone number memory to store a pager number; a cell phone mode integrated circuit having a digital to analog audio generating circuit, a dual tone telephone tone generator, a programmable phone number memory of sufficient size to store a contact phone number, and an audio message memory having an digitized audio message stored therein; a number entry keypad in user selectable connection with the programmable pager phone number memory and the programmable phone number memory; a two position selector switch wired in connection with the pager mode integrated circuit and the cell phone mode integrated circuit in a manner to allow a user to selectively enable operation of the pager mode integrated circuit and the cell phone mode integrated circuit; a cell phone power on control line output in connection with the activation cable; and a cell phone microphone circuit interface line that is connectable to the microphone circuit of a cell phone and that is in connection with the outputs of the pager mode integrated circuit and the cell phone mode integrated circuit; the pager mode integrated circuit being responsive to an activation signal on the activation cable when the pager mode integrated circuit is selected by the two position mode selector switch in a manner to generate the audio telephone dialing tones on the cell phone microphone circuit interface line that correspond to the stored beeper phone number; the cell phone activation circuit mode integrated circuit being responsive to an activation signal on the activation cable when the cell phone mode integrated circuit is selected by the two position mode selector switch in a manner to generate the audio telephone dialing tones on the cell phone microphone circuit interface line that correspond to the stored contact phone number and to then generate on the cell phone microphone circuit interface line analog audio signal that corresponds to the digitized digital audio message stored in the digital audio memory.

Although a conventional vehicle alarm can notify a vehicle owner within hearing range of an audible alarm horn or siren output, it does not have any mechanism for alerting a vehicle owner out of hearing range when an intruder or vehicle thief is attempting to burglarize or steal the vehicle. It would be a benefit, therefore, to have a cell phone activation circuit that was triggerable by a vehicle alarm system that could initiate a dialing sequence on a vehicle cell phone. In addition, because it may be desirable to dial either a cell phone or beeper number, it would be a benefit to have such a cell phone activation circuit that included a key pad to allow a user to enter one or more user selected dialing numbers. It would also be a benefit if the cell phone activation circuit included mode select circuitry to allow a user to select between a pager mode and a cell phone mode, and that included audio output circuitry for generating an audio message from stored digital audio message data stored within a digital audio memory.

It is thus an object of the invention to provide a vehicle alarm system triggerable cell phone activation circuit.
