[0001] Description of Related Art
[0002] Vehicle theft is a worldwide problem. An automobile can require an investment of a year of personal income. Cars are particularly important in automobile reliant cities such as Los Angeles. When a person's car is stolen, the car owner can also suffer a host of negative psychological injuries ranging from anxiety, depression, heart attacks and panic attacks. A well-designed automobile anti-theft device can deter car thefts and aid in vehicle recovery.
[0003] Traditional car alarms activate a siren or horn when an intruder opens a car door or breaks a window while the alarm is armed. These alarms have become less of a theft deterrent because the frequency of false alarms has conditioned people to ignore them. Car thieves have learned to disable traditional alarms allowing them to steal the car. This has lead to an ever increasing panoply of devices to foil car theft.
[0004] Many anti theft devices deactivate the engine. The Winbush Bold Thief Security System (5652564) disables a stolen car by means of a disabling signal that can be sent from a pager, wristwatch, or cell phone. Chen's Robbery-Repelling Alarm System (4646343) also gives the car a voice. Chen's device includes a taped message that shouts “Help”; or “We have been robbed”; or “arrest the burglar, please” while the ignition coil is deactivated and a phone call is made with a prerecorded message to the proper authorities. Tompkins created a Beeper Controlled Auto Security System (5600299). The Tompkins alarm system terminates the car's ignition through a radio or paging signal. It also includes silent homing signal to be received by the police or car owner. The homing signal sounds louder as the stolen car draws closer to the receiver. The Weinblatt Anti-Theft Automobile Security System (5635901) requires a two-step disabling process. Should a driver find himself being carjacked, he activates a first switch. Unfortunately, reaching for a hidden switch at gunpoint can be dangerous. After the owner is forced out of the car, the hijacker has to enter a code to keep the engine running.
[0005] Many car alarms page a person to give notice of a theft. Xiao created the Car Alarm Transmitting and Paging system (6028506). The Xiao system includes a normal pager that receives notification of car theft. When the car is stolen, the car sends an alarm to the pager. The Byrd Wide Area Wireless System (6049269) allows a communications link to any one of a fleet of cars to determine the car's identity and location. Dudley created the Vehicle Alarm System Triggerable Cell Phone Activation Circuit (6009320). A cell phone integrated with the car's circuit notifies the owner of the car theft. The cell phone in the car can dial multiple selected numbers to give notice of theft.
[0006] Suda created a Pager Vehicle Communication Apparatus (5990785). The Suda device remotely controls engine starting and stopping, door lock and unlock operations, and other vehicle accessories. The mirco controller receives commands from a telephone or pager and sends them to the stored control program. Notably, the CPU can check an RPM meter to allow activation of certain functions only when the car is at a low RPM, such as idle. Unfortunately, engine deactivation may still occur in dangerous situations such as if the vehicle stalls while climbing a hill or if the car is shifted into neutral.
[0007] Thus, a car theft deterrent device is desired that is inexpensive to install, can disable the engine safely, is difficult to disable, and does not give false alarms. It would also be desired that the device give notice of a car theft. These features should not hinder the towing of the car should it be necessary to do so.

[0008] Theft Notification
[0009] The Parker system can operate without an automatic notification means. A car owner usually learns of a theft upon return to the parking lot to see that the car is missing. After determining that the car was not towed by parking enforcement, the owner realizes that the car has been stolen.
[0010] The Parker system can operate with a notification means also. When a car is started, an ignition sensor sends a signal to the CPU, which in turn gives the owner notification. The notification means can be a cellular phone that sends a page to the owner. The owner can receive the page via a pager or cell phone. Alternatively, the owner can carry a fob, or a short-range radio receiver capable of receiving signals from a radio transmitter in the car.
[0011] Many car owners are the only drivers of their vehicle. Thus, notification of ignition is often the only notice necessary. Optionally upon ignition, a camera on the dashboard can take a photo of the driver and send the digital image to an embedded cell phone located on the car for storage. The Parker device can receive pager signals or a cellular or any other radio signals. The embedded cell phone then sends the digital image of the driver to the owner's cell phone. A digital photo can be fun for gadget lovers.
[0012] When a car owner discovers that his car has been stolen, he can activate the Parker alarm system
[0013] The system is comprised of a plurality of switches that can be implemented in a number of ways such as by software, through an integrated circuit, relays, or transistors. Two switches shown as
[0014] A first relay
[0015] Theft Recovery
[0016] The present invention allows a thief to continue driving a car while the alarm is activated. Engine deactivation is effective to stop a car, but can be dangerous when the car is moving. Present vehicles have power steering and power braking that can fail if the engine is deactivated. A car without engine power can be dangerous especially when it is descending a steep hill.
[0017] Upon hearing the horn or alarm sound, some thieves will continue driving, and the horn and lights will help the police recover the vehicle. Other thieves will stop and abandon the car. More determined thieves will attempt to deactivate the alarm. In that case, a thief usually stops the car and turns off the engine. Then he can access the hood to physically disconnect the alarm or access the area under the dashboard and steering column. Should the thief turn off the car, he would be unable to restart the car because the engine starter has been deactivated. The third relay
[0018] Car thieves often try to disable car alarms by delivering a high voltage surge to the electrical system. The surge blows the secondary fuses while leaving the starter fuse intact. After the secondary fuses are blown, the thief can start the car with ease. A car usually contains a number of fuses. The electric starter mechanism of a car has a high surge capacity before it is disabled. Secondary fuses have a lower voltage requirement before they disable secondary systems such as: lights, audio system, alarm system, or power locks. A thief can remove the electrical panel underneath the steering column, find two wires and deliver a surge from a compact battery having the appropriate voltage transformer attached to jumper cables. The present invention includes diodes
[0019] An expensive car without a traditional alarm can raise the suspicions of a car thief. A cautious car thief may suspect a silent or latent alarm and attempt to deliver a prophylactic surge to the car's electrical system. The Parker system can be modified to detect a surge, trigger the engine ignition lock, and activate the alarm.
[0020] A car thief can also disable a car alarm by physically opening the hood and disconnecting certain parts of the car alarm or car battery. The hood lock prevents the disabling of the alarm in this manner.
[0021] After Recovery
[0022] After the owner has recovered the vehicle, the owner can dial the system with a code off such as 2222 to reactivate the vehicle's normal operations. Other codes can control other functions in the car. A code 3333 for example, can unlock the doors to aid in car recovery. There can be a plurality of codes. Also, a plurality of pagers can be used instead of a plurality of codes. The system can also be reduced to an integrated circuit, although relays are preferred for their resistance to surges.
[0023] The present invention uses a pager receiver in a car to actuate certain functions. The preferred embodiment has a pager sending a 1.5V signal to a 1.5V relay that actuate the second relay
