Abstract
A safety system and method for remotely activating and/or deactivating firearm(s). In certain embodiments, at least one processor or chip may be provided in the firearm. In order to remotely activate a firearm and allow it to be discharged, a controller (located remotely from the firearm) causes an activation signal to be sent to a satellite. The satellite redirects the activation signal toward a particular geographical area. When the firearm to be activated is in that geographical area, it receives the activation signal from the satellite. Upon determining that a match is found between a code in the received activation signal and a predetermined activation code stored in a memory of the firearm, the processor in the firearm causes a trigger lock in the firearm to open thereby enabling the firearm to be discharged whenever a user should decide to load the weapon and pull the trigger. Firearms may be remotely deactivated in a similar manner by way of satellite communication, or any other type of wireless communication such as from a remotely located police transmitter.
Description




This invention relates to a gun or firearm safety system and corresponding method. More particularly, this invention relates to a remotely activatable trigger lock or other safety for a gun which enables a central controller such as a Government authority or a Police Department to selectively activate or deactivate select firearms in different geographical areas throughout the world.




BACKGROUND OF THE INVENTION




U.S. Pat. Nos. 5,461,812; 4,488,370; and 5,459,957 disclose gun safety systems, and are all hereby incorporated herein by reference.




Firearm (e.g. gun) safety is a worldwide concern. Standard in many weapons is a thumb safety and/or grip safety which reduces unintentional firearm discharges. Thumb safeties may operate by manually shifting a safety lever from a safe position to a fire position. Grip safeties may be automatically shifted to fire positions when a user's hand engages the stock of the weapon or even the trigger of the weapon. Neither of these types of safety mechanisms is completely effective to prevent the unauthorized use of a firearm, and thus have proven unsatisfactory in dealing with a variety of safety concerns. Moreover, these prior art systems cannot prevent stolen, or select, weapons from being discharged.




A concern of law enforcement officials is the prevention of law enforcement officers being shot at or killed with an officer's own service weapon. Another concern is firearms of any type being utilized against law enforcement officers. Another concern is the exportation from the United States of U.S. made firearms which ultimately become used against U.S. troops or citizens in foreign countries. For example, it would be undesirable if foreign militaries or terrorists were able to acquire and use U.S. made weapons against U.S. soldiers or U.S. citizens.




There have been prior art attempts to make a weapon operable only by specific authorized users. Some prior art devices require that the user wear a special signal generating (i.e. active) component, such as a ring, bracelet, or glove. In these devices, the firing mechanism will only operate in the presence of a signal generated by the active device. Such devices are deficient for a number of reasons. The active components are cumbersome and uncomfortable to wear, thereby decreasing user acceptance and making the system less reliable. Additionally, the devices are not unique to a given user or a given geographical area because the weapon can still be operated by anyone who has the required signal generator in any area of the world. Another problem is that a firearm cannot be quickly enabled if the user is not presently wearing, or loses, the signal generating device.




In view of the above, it is apparent that there exists a need in the art for police authorities or governmental authorities to be capable of remotely activating and/or deactivating particular or select firearms in different geographical areas around the world. There also exists a need in the art for police or law enforcement officers to be capable of remotely activating or deactivating weapons which may be utilized against them, on short notice.




It is a purpose of this invention to fulfill the above-described needs in the art, as well as other needs which will become apparent to the skilled artisan from the following detailed description of this invention.




SUMMARY OF THE INVENTION




It is an object of this invention to enable Governmental authorities to remotely activate and/or deactivate select firearms in different geographical areas around the world.




It is another object of this invention to allow law enforcement officers (e.g. police officers) to remotely deactivate firearms which they perceive, on short notice, to potentially be utilized against them.




It is another object of this invention to utilize a satellite to enable Governmental authorities and/or law enforcement authorities to remotely deactivate and/or activate select firearms.




It is still another object of this invention to provide firearms with a processor chip therein which is capable of receiving deactivation and/or activation signals from a satellite in order to selectively deactivate/activate the firearm. When activated, the firearm may be utilized to fire or discharge bullets, and when deactivated a trigger lock or the like may be utilized to prevent the firearm from being discharged.




Another object of this invention is to provide a plurality of firearms, each with at least one processor chip therein which receives remote orders from a satellite or from a police transmitter in order to activate or deactivate the firearm. In such a manner, in certain embodiments, firearms may be shut down or deactuated by way of a trigger lock if they are reported or believed to be stolen.




Still another object of this invention is to provide a system for deactivating/activating firearms via satellite signals, by way of selective frequencies and/or codes being transmitted to firearms via satellites. In such a manner, the frequencies and/or codes may be changed on a daily basis for security purposes, with the chip in each firearm being programmed in advanced to know which frequencies and/or codes may be utilized on particular days of the year to activate or deactivate each firearm.




It is still another object of this invention to permanently deactivate a firearm (e.g. gun) if a processor chip therein is removed, tampered with, or deactivated.




This invention further fulfills the above identified needs in the art by providing a method of distributing, activating, and deactivating a firearm, the method comprising:




providing a firearm including a receiving antenna, a processor, a memory, and a locking device for selectively preventing the firearm from being able to be discharged;




distributing the firearm;




transmitting an activation signal, via a transmitting antenna located remote from the firearm, to a satellite;




the satellite receiving the activation signal including activation information therein;




the satellite transmitting an earthward-directed signal toward a first geographic area on planet earth, to the exclusion of other geographic areas on planet earth;




the firearm being located in the first geographic area and the receiving antenna of the firearm receiving the earthward-directed signal from the satellite;




the processor of the firearm causing the locking device to unlock in response to detection of the receiving antenna receiving the earthward-directed signal from the satellite so that the firearm may be discharged;




transmitting a deactivation signal, via a transmitting antenna located remote from the firearm, to the satellite;




the satellite receiving the deactivation signal including deactivation information therein, and in response thereto transmitting an earthward-directed deactivation signal toward the first geographic area on planet earth; and




the receiving antenna of the firearm receiving the earthward-directed deactivation signal from the satellite and the processor in response thereto causing the locking device to lock the firearm against discharge so as to prevent the firearm from being discharged.




This invention still further fulfills the above described needs in the art by providing a system for deactivating a firearm and preventing the firearm from discharging, the system comprising:




the firearm including a receiving antenna, a processor, a memory, and means for selectively preventing the firearm from discharging;




an antenna located remote from the firearm, said antenna for transmitting a deactivation signal to at least one satellite;




said at least one satellite for receiving the deactivation signal;




said at least one satellite for transmitting an earthward-directed deactivation signal toward a first geographic area on planet earth, to the exclusion of other geographic areas on planet earth;




the firearm being located in the first geographic area, and the receiving antenna of the firearm receiving the earthward-directed deactivation signal from said at least one satellite; and




the processor of the firearm, in response to detecting reception of the earthward-directed deactivation signal, causing the means for selectively preventing the firearm from discharging to prevent the firearm from being discharged.




This invention will now be described with respect to certain embodiments thereof, along with reference to the accompanying illustrations.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS OF THIS INVENTION




Referring now more particularly to the accompanying drawings in which like reference numerals indicate like parts throughout the several views.





FIG. 1

is a side plan view of a firearm


1


. Firearm


1


may be a hand-gun, rifle, grenade launcher, anti-tank weapon, or any other type of firearm operable by a human operator. For example, firearm


1


may be a 9 mm pistol such as a Glock 17, or alternatively may be an assault rifle such as an AK-47, M-16, or the like.




Firearm


1


includes a system for electronically enabling its operation for intended use. Firearm


1


includes trigger


3


, trigger guard


5


, plastic or metal body housing


7


, metallic bore area


9


, magazine


11


for holding a number of bullets which may be selectively inserted and/or removed from housing


7


, and barrel


13


which extends through member


9


. A processor chip


15


is mounted on or within firearm


1


. Firearm


1


is only permitted to be fired or discharged when processor


15


unlocks or opens trigger lock


17


(i.e. thereby activating the weapon). Processor


15


may be instructed to either activate (unlock trigger guard) or deactivate (lock trigger guard) firearm


1


from a remote location by way of radio signals, satellite signals, microwave signals, or the like.





FIG. 2

illustrates a schematic or block diagram of a safety system and method which may be utilized to remotely activate or deactivate firearm


1


so as to either allow the firearm to be discharged or to cause it to be locked in order to prevent its discharge. The safety system includes central controller


21


, memory


23


, modulator


25


, and transmitting antenna


27


which are at a given location preferably remotely located relative to firearm


1


. Components


21


-


27


may communicate with firearm


1


by way of satellite


29


or any other atmospheric-free space telecommunications method or system (e.g. microwave, radio signals, etc.). In certain optional embodiments, a police transmitter


31


may also be provided at a location remote from firearm


1


.




Attached to, or within, firearm


1


are receiving antenna


33


, signal demodulator


35


, processor or controller chip


15


, comparator


37


, memory


39


, trigger lock or other mechanical activation/deactivation mechanism


17


, and battery


41


for supplying electrical power to these elements within firearm


1


.




According to certain embodiments of this invention, a Governmental authority or anyone else may sell or otherwise distribute a plurality (e.g. thousands) of firearms


1


to customers throughout the United States or anywhere else throughout the world. Each of these firearms may include a processor


15


, trigger lock


17


, and each of the other elements


33


-


41


shown in FIG.


2


. Each firearm, upon shipment or sale, may in certain embodiments be programmed so that the trigger lock


17


is in a position or state so as to prevent the firearm from being discharged or fired. Thereafter, at a given point in time, a Governmental authority or police authority may activate select firearms as follows. Such authority may cause controller


21


to look up in memory


23


to determine the frequency or code needed to activate a particular firearm


1


(or group of firearms


1


) based upon predetermined serial number(s) or identification number(s) of the firearm(s) to be activated. Upon determining the appropriate digital activation code or frequency from memory


23


, controller


21


outputs a signal which is modulated at


25


and is thereafter transmitted at


27


through atmospheric free space to satellite


29


as signal


45


. Signal


45


(and


47


) may be modulated in a spread spectrum manner, via QPSK, via DQPSK, via OPQSK, via QAM, via TDM, via COFDM, or any other appropriate type of modulation.




After satellite


29


receives activation signal


45


, it in turn directs this same activation signal toward a particular geographical area on Earth as signal


47


(e.g. into a particular country, state, county, portion thereof or continent). Firearms


1


located in that particular geographical area receive activation signal


47


by way of antenna


33


. Firearms


1


not in that geographical area do not receive the activation signal.




Upon reception by a firearm of activation signal


47


, which passes through antenna


33


, the demodulator


35


in the firearm


1


demodulates the signal so that it can be interpreted by way of either the demodulator


35


or processor


15


. Thereafter, processor


15


causes the received information to be compared predetermined information (e.g. bit code) stored in memory


39


, by way of comparator


37


. If processor


15


or the comparator determines, from this comparison in comparator


37


, that the information bits from the received activation signal


47


matches one of a predetermined number (e.g. 1-100) of activation signals (e.g. bit code) stored in memory


39


, then the processor instructs trigger lock


17


to unlock and thus activate the firearm and allow trigger


3


to be pulled so as to enable the firearm


1


to be discharged when desired by a user.




For example, according to certain embodiments, the aforesaid plurality of firearms


1


could be made in the U.S. and exported from the United States to a foreign country such as Israel, U.K., or Saudi Arabia. After arriving in the foreign country, controller


1


may cause an activation signal


45


to be sent to a particular satellite or group of satellites


29


which in turn direct(s) activation signal(s)


47


toward a particular geographical location (e.g. to cover the foreign country or portion thereof) and thus toward at least a plurality of the firearms. Thus, only those firearms which made their way to that intended particular geographical area are activated so as to enable only those firearms to be capable of being discharged by users. Firearms


1


which, for one reason or another, such as being stolen, do not reach their intended destination in the foreign country will remain deactivated and will not receive or be activated by signal


47


which is only directed toward the specific geographical location (e.g. in Saudi Arabia, U.S., and/or Israel). The activated firearms may remain activated for either a short or a long period of time. For example, they may remain activated for five (5) years, or only one (1) week. If, however, there becomes a need to deactivate these activated firearms (e.g. they are captured or stolen by a foreign Government or terrorists, and potentially could be used against U.S. troops or citizens), then controller


21


can access memory


23


in order to determine a deactivation code or frequency to be used to deactivate those particular select firearms


1


. The controller


21


can retrieve this deactivation code or frequency, cause it to be modulated at


25


, and cause antenna


27


to transmit or generate the deactivation signal


45


and direct it toward satellite


29


which can redirect it as deactivation signal


47


toward a given geographical location (e.g. throughout portions of Saudi Arabia, Iraq or the like). Firearms


1


receiving the deactivation signal


47


from satellite


29


will receive it by way of antenna


33


, demodulate it at


35


, process it at


15


, and compare it at


37


with known activation and deactivation bit code signals stored in memory


39


. If processor


15


determines that the received bit information or signal


47


matches that of a known deactivation signal from memory


39


for that particular firearm, then processor


15


causes trigger lock


17


of firearm


1


to lock trigger


3


against movement so as to deactivate the weapon and prevent it from being fired. The firearm remains deactivated until it receives an activation signal from the satellite.




Moreover, in certain embodiments of this invention, any removal, tampering with, or attempt to remove processor


15


or trigger lock


17


from firearm will cause the firearm to be permanently deactivated. Trigger lock


17


may instead be replaced with other types of mechanical or electrical activation/deactivation devices in the weapon.




In such a manner, if weapons originating from the United States make their way into the hands of terrorists or other undesirables, it is possible to deactivate these weapons selectively from a remote location, i.e. once they make their way into the hands of terrorists or governments adverse to the United States. Again, activation signals may activate firearms


1


at any time, and deactivation signals may deactivate them at any time. Each firearm


1


may be activated or deactivated any number of times, from one through thousands. Memory


23


may store therein from 1-1,000 activation and/or deactivation codes for each particular firearm based upon the serial number or other identification number of that firearm.




According to certain other embodiments of this invention, the safety system of

FIGS. 1-2

may be utilized to deactivate firearms which are stolen either from individuals, the military, or from police officers. For example, if a given firearm is reported as being stolen or even lost, controller


21


can look up in memory


23


predetermined digital codes or frequencies which may be utilized to deactivate that particular firearm based upon its serial number or ID number. Such codes or frequencies in memory


23


may be stored at addresses corresponding to particular serial number(s) of different firearm(s)


1


. Once controller


21


determines which deactivation digital code or frequency to be utilized for that firearm, it retrieves this code from memory


23


, causes it to be modulated at


25


with a carrier signal, and transmits it


27


toward satellite


29


as deactivation signals


45


. Satellite


29


redirects these deactivation signal(s) toward a predetermined geographical area (e.g. the entire United States or a portion thereof) as deactivation signal(s)


47


where the stolen firearm is expected to be located. If the stolen firearm


1


receives this deactivation signal


47


, it does so by way of receiving antenna


33


. The signal is then demodulated at


35


and forwarded to processor


15


. Processor


15


compares the deactivation signal information with a deactivation signal code or signals stored in memory


39


by way of comparator


37


. If a match is found with a deactivation signal from memory


39


, then processor


51


determines this match and automatically instructs trigger lock


17


to prevent the firearm from being discharged (i.e. to deactivate the stolen firearm). In such a manner, stolen firearms, identifiable by serial number or the like, may be deactivated from remote locations by way of satellite


29


to prevent thieves or foreign governments from utilizing stolen firearms. Firearms


1


may optionally include an ID transmitter therein for helping stolen weapons to be located.




Moreover, as set forth above, any removal or attempt to remove processor


15


or any other of components


33


-


41


from firearm


1


will cause the firearm to automatically deactivate and not be able to be discharged.




Once the firearm


1


is recovered, and returned to its original owner, controller


21


can access an activation signal from memory


23


at a location in the memory corresponding to the serial number of the firearm. Controller


21


retrieves this activation signal from memory


23


, causes it to be modulated at


25


and transmitted


27


toward satellite


29


. The satellite redirects the activation signal toward receiving antenna


33


of the firearm, and after processor


15


determines that the activation signal matches an activation signal stored in memory


39


at comparator


37


, the processor


15


automatically instructs the trigger lock


17


to open thereby again activating firearm


1


and allowing it to be discharged. If no match is found, then the firearm will remain deactivated.




According to still further embodiments of this invention, individual police cars or policemen may carry police transmitters


31


. A police transmitter


31


, when activated by a police officer, may transmit a generic deactivation signal


61


in all directions at a low strength so as only to be received in a predetermined area (e.g. up to about 100-1,000 yards from the transmitter


31


). Thus, should a police officer carrying a transmitter


31


encounter a thief or other criminal who is attempting to use a firearm


1


against the officer, the officer may activate his or her transmitter


31


and cause a deactivation signal


61


to be output. The firearm


1


in the hands of the criminal receives deactivation signal


61


by way of antenna


33


. The firearm then demodulates the deactivation signal at


35


and processor


15


causes the received bit or signal information to be compared with generic signals or information in memory


39


by way of comparator


37


(the firearm may store both generic deactivation codes and the serial number specific codes mentioned above in its memory). If processor


15


, by way of comparison


37


, determines that the received bit information or signal


61


matches a generic deactivation code or signal stored in memory


39


, then processor


15


instructs trigger lock


17


to lock trigger


3


against movement thereby deactivating the firearm


1


. Thus, an officer may, by activating transmitter


31


, prevent a proximate firearm


1


from being used against the officer. At a later point in time, after the criminal has been apprehended, the firearm


1


may be reactivated either by way of controller


21


sending an activation signal


45


based on the serial number of the firearm


1


, or alternatively by police transmitter


31


emitting an activation signal that is either a generic activation signal or an activation signal based upon the serial number of the firearm. Police transmitter


31


may be worn on the wrist of a police officer, it may be located in a police cruiser, or may even be attached to a firearm carried by a police officer so that the officer can easily activate transmitter


31


while the officer is handling his or her weapon. Optionally, transmitter


31


may transmit short-term deactivation signals which causes a firearm to be deactivated for only a predetermined period of time (e.g. one (1) hour), and thereafter automatically reactivate.




According to still other embodiments of this invention, memory


39


in the firearm


1


and memory


23


can each store a plurality of different activation and/or deactivation digital codes or frequencies. For example, each memory


39


and


23


may store a different activation code or frequency for each day of the year, and/or a different deactivation code or frequency for each day of the year (only one code will work on a given date). Processor


15


and controller


21


may each include a timer which keeps track of the date of the calendar year and may each retrieve the code from the corresponding memory based upon the date. Thus, both memory


23


and memory


39


may store up to three hundred sixty-five (365) different deactivation codes or frequencies for each firearm


1


and up to three hundred sixty-five (365) different activation codes or frequencies for each particular firearm


1


, as designated by the firearm serial number or other identification number. Accordingly, when it is desired to deactivate a firearm


21


on e.g. Jul. 27, 1999, then controller


1


will retrieve from memory


23


the particular deactivation code or frequency specified for that particular date for the select firearm as designated by its serial number. Controller


21


will then cause it to be modulated and transmitted to satellite


29


which redirects the signal toward an area believed to include the firearm


1


. If the firearm receives it, the processor


15


retrieves from memory


39


the appropriate activation and deactivation signals for that particular date. Comparator


37


performs a comparison between the signal received from the satellite and the two signals received from memory


39


. If a match is found with the deactivation signal retrieved from memory


39


for that particular date, then processor


15


instructs trigger lock


17


to lock the firearm and deactivate it. Meanwhile, if a match is found between the received signal


47


and the activation signal retrieved from memory


39


for that particular date, then processor


15


instructs the trigger lock to open. The storing of date-precise activation and deactivation signals in memories


23


and


39


increases the overall security of the system and helps to prevent unauthorized discharging of weapons.




According to certain embodiments, the invention may further include the step of changing identification information stored in the firearm at predetermined or random intervals, and at least one of activation or deactivation of the firearm being possible only when the firearm determines or detects that a received signal includes information indicative of or matching correct identification information stored in the firearm at the time the received signal is received by the firearm.




Once given the above disclosure, many other features, modifications, and improvements will become apparent to the skilled artisan. Such other features, modifications, and improvements are, therefore, considered to be a part of this invention, the scope of which is to be determined by the following claims.
