U.S. Patent No. 5,729,192 (Badger), discloses a device and method for remotely disabling an automobile by transmitting a signal which is received by a receiver of a single vehicle. The receiver of the Badger patent is controllably connected to a circuit which is able to interfere with the connection of the operating voltage to the ignition components of the automobile. The Badger patent focuses on electricity principles rather than electronics, whereas today most cars have electronic circuits to control the electrical functions. It is desirable to provide a device and system for remotely controlling a plurality of vehicles within a particular radius with the transmission of a single signal. It is further desirable to provide a remote control device and system for remotely controlling vehicles within a particular radius for use by law enforcement agencies. It is also desirable to provide a device and system for remotely reducing the speed of vehicles within a particular radius in which the speed of the vehicles is first reduced so that the vehicles are slowed down and then reduced further until the vehicles are stopped or immobilized.
SUMMARY OF THE INVENTION The present invention provides a remote control device and system for remotely reducing the speed of at least one vehicle within an activation radius comprising a remote device for use by a law enforcement agent and a receiver which is located in all vehicles. The remote device, when activated by a law enforcement agent, sends a wave coded signal to the receivers in all vehicles within a pre-determined radius of the remote device. Once the "Reduce Speed" signal is received, the speed of the vehicles is first reduced to a speed of about 5-10 mph, and, if the vehicle sought after has not stopped and if it is safe to do so, then if the "Stop" signal is received, the speed of all of the vehicles is further reduced such that the vehicles are stopped or immobilized. It is an object of the invention to provide a remote control device and system for remotely reducing the speed of at least one vehicle with the transmission of a single signal. It is an object of the invention to provide a remote control device and system for remotely reducing the speed of all vehicles within a pre-determined radius.

DETAILED DESCRIPTION OF THE INVENTION The following is a description of one preferred embodiment as well as certain alternative embodiments of the present invention. Further embodiments will become apparent to those skilled in the art. The following description is merely illustrative of the present invention and is not to be construed as limiting the scope of the present invention. Referring to FIG. 1, the preferred embodiment of the present invention is comprised of the following devices: (1) the Remote Vehicle Stopper (RVS) 10 in the law enforcement agency vehicle, (2) the Vehicle Stopper Receiver (VSR) 20 in all vehicles and (3) a Vehicle Stopper Controller (VSC) 30. In the preferred embodiment, the Remote Vehicle Stopper 10 is a device located in a law enforcement agency vehicle (for example, a police car, truck or bus, but it could also be a motorbike, bike, boat or helicopter) and operated by an identified law enforcement agent (for example, a police officer or other law enforcement agent). The Remote Vehicle Stopper device 10 is a secured device in the preferred embodiment. Means of securing the Remote Vehicle Stopper 10 include, but are not limited to, for example, the following: smart card, password, biometric reader, electronic key, magnetic strip card and access card. The Remote Vehicle Stopper 10, when operated by the authorized law enforcement agent, will reduce the speed of any "civilian" vehicle within the activation radius by sending a wave coded signal to a receiver (Vehicle Stopper Receiver 20) located in all vehicles (car, van, truck, bus, motorbike or boat). Traceability is an important feature of this invention. The public and the law enforcement agencies would like to make sure that a powerful tool like the Vehicle Stopper System is operated properly and according to the law and regulations. To achieve these objectives, law enforcement agencies will have a procedure for authorizing use of the present invention such that use of the Vehicle Stopper System will be secured and recorded and the law enforcement agents using the system will be identified. All of these functions will provide a high level of traceability and security. The Remote Vehicle Stopper 10 has a plurality of buttons for selecting various functions, for example, "Reduce Speed," "Stop," "Restore," etc. and may be shaped, for example, like a car radio with a LCD screen to guide the law enforcement agent as shown in FIG. 3. The Remote Vehicle Stopper device 10 is linked to the computer and database of the chain of command of the law enforcement agency.
In another embodiment, the Remote Vehicle Stopper is a hand held device 50 and is linked to another device located in the law enforcement agency vehicle, the Vehicle Stopper Base 60, as shown in FIG.4. The link between these two devices is secured mechanically, electronically and electrically. The Vehicle Stopper Receiver (VSR) 20 is the receiver located in the "civilian" vehicle. To operate effectively, a receiver 20 should be located in all "civilian" vehicles, which receiver is similar to the antitheft devices used to protect vehicles from being stolen. The receiver 20 should also be tamperproof like the antitheft devices. Police vehicles, Fire Department vehicles, ambulances and other equivalent vehicles (including armored cars) will have a Vehicle Stopper Receiver 20 but it will be deactivated while on duty so that such vehicles will not be stopped by the present invention. When the Vehicle Stopper Receiver 20 receives the proper wave coded signal, i.e. if the police officer (or other law enforcement agent) has pushed a first button (i.e. "Reduce Speed" button) on the Remote Vehicle Stopper 10, the fuel supply is reduced so that the speed of all of the civilian vehicles in the activation radius is reduced to about 5 to 10 miles per hour. In another embodiment, the civilian vehicles' warning lights will blink slowly in response to the "Reduce Speed" wave coded signal. If the police officer (or other law enforcement agent) presses a second button ("Stop" button) on the Remote Vehicle Stopper 10, the system cuts the fuel supply or ignition of all civilian vehicles within the activation radius and the speed of the vehicles is reduced such that the vehicles are stopped or immobilized. Additionally in another embodiment, the civilian vehicles' warning lights will blink quickly in response to the "Stop" wave coded signal. In the preferred embodiment, the Remote Vehicle Stopper 10 will not stop all vehicles in the activation radius abruptly, although capable of doing so. It will reduce the fuel supply first so that all maneuvering capabilities of the vehicles are not lost. The fuel supply is reduced so that the speed of the vehicles is reduced to a maximum speed of about 5 to 10 mph. If the law enforcement agent chooses to press the "Stop" button of the Remote Vehicle Stopper 10, then the ignition or fuel supply of the vehicles in the activation radius will be cut. This is based on the assumption that all modern vehicles have an electronically controlled fuel injection system. For vehicles not having electronic fuel injection systems, it will not be possible to reduce the fuel supply. Accordingly, only the "Stop" button will be effective. The law enforcement agent can give back the fuel supply and ignition control to the civilian vehicles if he or she chooses to do so by pressing a third button on the Remote Vehicle Stopper ("Restore" button) 10. When activated, used and deactivated, the Remote Vehicle Stopper device 10 will send a signal to the law enforcement agency headquarters to report the situation.
The Remote Vehicle Stopper 10 will also have the ability to activate the warning lights of the vehicles within the activation radius to test vehicles on the road or at a toll booth, for example. The activation radius of the present invention may be varied enabling the control of either a wide range of vehicles or a much more limited number of vehicles, including a single vehicle. For example, the activation radius may be about 100 to 300 feet, providing for the control of potentially numerous vehicles. Alternatively, the activation radius may be reduced to about 3 to 10 feet, providing for the control of a single vehicle. The activation radius may be varied, for example, by increasing or decreasing the strength of the transmission of the wave coded signal. In alternative embodiments, the activation radius may be limited using such means as metal shields, for example, using a Faraday Cage or similar device to create a controlling station managed by the Vehicle Stopper Controller 30. The wave coded signal is a secured digital radio signal in a dedicated bandwidth. This signal may be secured using, for example, an adaptation of the Wireless Transport Layer Security Protocol. The Vehicle Stopper Controller 30 is a computer station with a receiver and a transmitter which controls, manages, and updates the Remote Vehicle Stopper 10 and the Vehicle Stopper Receiver 20 (and the Vehicle Stopper Base 60 in the embodiment where such device is used). The Vehicle Stopper Controller 30 is also a secured device in the preferred embodiment. Means of securing the Vehicle Stopper Controller 30 include, but are not limited to, for example, the following: smart card, password, biometric reader, electronic key, magnetic strip card and access card. The Vehicle Stopper Controller 30 sends data to a computer network that is part of the chain of command of the law enforcement agency. This network and these computers will be securely connected and protected. If a GPS is in the law enforcement agency vehicle, the localization data will also be sent to the law enforcement agency headquarters. If the law enforcement agency vehicle is out of range of the headquarters, it will store data for uploading to a computer system, the Vehicle Stopper Controller (VSC) 30, at a later time. This feature will add another element of traceability as the one described above.
Referring now to Fig.'s. 2 and 5, another embodiment of the invention includes a Vehicle Stopper Transmitter (VST) 40, which is located in all vehicles. In one embodiment, for example, the Vehicle Stopper Transmitter 40 may be located next to the Vehicle Stopper Receiver 20. The Vehicle Stopper Transmitter 40 sends various types of data, for example, vehicle identification data (such as the vehicle identification number and registered license plate number) and status data, back to the Remote Vehicle Stopper 10 and the Vehicle Stopper Controller 30 so that the law enforcement agent can, for example, compare it to what he sees on the vehicle license plate. All components of the system of the invention should be tested regularly. In particular, the Vehicle Stopper Receiver 20 should be checked regularly to make sure it works as expected and that it has not been deactivated. The testing should be done around some well selected places such as toll booths, banks which have been repeatedly robbed, embassies, customs, etc. The Vehicle Stopper Receiver 20 will answer by sending a particular signal (the system will be in testing mode and will not stop the vehicle). The system should be tested completely during inspection of the vehicle to confirm that the vehicle slows down and stops as it should when so activated by the law enforcement agent. A checking station equipped with a Vehicle Stopper Controller 30 will automatically check to verify that each vehicle tested responds as expected, and in embodiments including a Vehicle Stopper Transmitter 40, will also confirm that the vehicle tested is not one of a list of vehicles to be apprehended. In order to test only a single vehicle, either the activation radius will be reduced or the use of a metal shield such as a Faraday Cage may be employed. Other means of reducing the activation radius may also be employed. The Vehicle Stopper Controller 30 transmits a signal to the Vehicle Stopper Receiver 20 of the vehicle to confirm that it responds as expected. In the embodiment including a Vehicle Stopper Transmitter 40, the Vehicle Stopper Controller 30 transmits a signal to the vehicle requesting vehicle identifying data, for example, the vehicle identification number. The Vehicle Stopper Transmitter 40 transmits the requested data back to the Vehicle Stopper Controller 30. The Vehicle Stopper Controller 30 determines whether this vehicle is on the list of vehicles to be apprehended. If the Vehicle Stopper Receiver 20 of the vehicle does not work properly, or if the vehicle is sought after or on the list of vehicles to be apprehended, the tested vehicle will be stopped either automatically by the Vehicle Stopper Controller 30 sending a signal to the Vehicle Stopper Receiver 20, or the driver of the vehicle will be asked to stop and a picture of the vehicle and license plate will be taken. If the driver of the vehicle does not stop the vehicle, the vehicle should be stopped by traditional means. A law enforcement agent may also activate the Remote Vehicle Stopper 10 to transmit a wave coded signal to all vehicles in a wider radius in this scenario, thereby reducing the speed of at least the traffic around the fleeing vehicle. The Vehicle Stopper Controller 30 may be operated automatically or by a law enforcement agent.
This invention may be used to block vehicles efficiently when their owners have not paid taxes, parking tickets, etc. or because they should be arrested. It will avoid the use of the "Denver boot" or other vehicle immobilization device. A law enforcement agent may also determine whether a vehicle is sought after or on a list of vehicles to be apprehended by activating the Remote Vehicle Stopper 10, sending a signal to the Vehicle Stopper Transmitters 40 of the vehicles within the activation radius requesting vehicle identification data. The Vehicle Stopper Transmitters 40 of the vehicles in the activation radius will send their vehicle identification data back to the Remote Vehicle Stopper 10, at which time the law enforcement agent may determine whether any one of the vehicles within the radius should be stopped. The law enforcement may then elect to reduce the speed of all of the vehicles within the activation radius. In another embodiment of the invention, if it is determined at a checking station, for example, that a vehicle is sought after or that a law enforcement agency desires to stop a particular vehicle, the vehicle may be stopped at a pre-determined time including, for example, the next time the vehicle is started, after the vehicle is started a certain number of times (i.e. the fifth time the vehicle is started) or after a certain number of miles (i.e. after 50 miles). In this embodiment, only a single vehicle is controlled by either varying the activation radius or through the use of a device such as metal shield or a Faraday cage. In addition to testing that the speed of vehicles can be reduced, the Vehicle Stopper Controller 30 and Vehicle Stopper Transmitter 40 should be regularly tested to check that the Vehicle Stopper Controller 30 is receiving valid vehicle identification data such as the vehicle identification number from the Vehicle Stopper Transmitter 40. When circumstances allow, for example, during vehicle inspection, a real comparison will be done between the vehicle identification number and/or the license plate number visible on the screen of the Vehicle Stopper Controller 30 and the actual vehicle identification number on the engine and/or the license plate number on the vehicle. To avoid jamming, the civilian vehicle will be stopped if a jamming device is detected (all frequencies of the range with a powerful signal). Otherwise, it could be possible for a professional robber to put a very primitive jammer (emitter working on all the range of frequencies concerned and powered by a battery) in the vehicle he or she wants to steal or avoid to be stopped by the law enforcement agents. The signal sent by the jammer will mask the signal sent by the law enforcement agent and the Remote Vehicle Stopper 10 will not operate. So to circumvent this flaw, the Vehicle Stopper Receiver 20 reduces the fuel supply if a powerful signal is detected which looks like a jamming signal. For vehicles without fuel injection, the jamming will stop the ignition. In this case, if there is a dangerous environment, like a railroad, for example, a special button on the civilian vehicle will allow for a few seconds to delay the stopping process. This feature will assist a driver in exiting a dangerous area (for example, railroad, freeway, etc.) or an area where there is a lot of industrial noise (for example,
manufacturing plant, arc welding station, etc.) by delaying the effect of the anti-jamming process for a few seconds. In case of industrial noise (electronic emission of radio waves), which may have the effect of jamming, the Vehicle Stopper Receiver 20 will reduce the fuel supply of the vehicle and it will still be possible to drive the vehicle at a reduced speed until the vehicle is outside of this difficult electromagnetic environment. For vehicles without fuel injection, the industrial noise will stop the ignition. In this case, if there is a dangerous environment a special button may be used as described above. Another use of this invention may be to automatically reduce the speed of all vehicles under specific circumstances, for example, near a school or a school bus, a road block, in case of emergencies, etc. It will be clear that the present invention is well adapted to carry out the objects and attain the ends and advantages mentioned as well as those inherent therein. While certain embodiments have been described for purposes of this disclosure, numerous changes may be made which will readily suggest themselves to those skilled in the art and which are encompassed in the spirit of the invention disclosed.
