BACKGROUND OF THE INVENTION




1. Technical Field




The present invention relates generally to weapons systems and more particularly, to the tracking of weapons.




2. Description of Related Art




Gun control has become an important issue in today's society. There are far too many instances in which deranged individuals wreak havoc by shooting innocent victims. Even more distressing, such shootings, particularly those done at random, are difficult to solve and strike fear into our nation's citizens. In response, several legislatures have enacted laws and regulations in an effort to prevent unauthorized persons from obtaining firearms.




For example, in 1993, the U.S. Congress passed and the President signed into law the Brady Handgun Violence Prevention Act. Commonly referred to as the Brady Bill, this legislation established a national system of background checks and waiting periods for individuals purchasing guns from federally licensed firearms dealers. Primarily designed to prevent convicted felons from obtaining guns and to provide purchasers with a “cooling off” period, the Brady Bill has been somewhat successful in preventing gun violence. Other initiatives have been advanced to further control access to firearms including requiring gun owners to place locks on their guns to eliminate accidental shootings.




Nevertheless, many proponents of gun control remain convinced that it is too easy to obtain a firearm in this country. As an example, these people argue that the Brady Bill has several loopholes in that it does not apply to gun shows and that nothing is in place to prevent guns from being purchased over the black market or simply stolen from a legal owner and later used to further criminal activity. Indeed, once a gun is acquired (illegally or even legally), presently there is no way to stop the weapon from being used or to monitor the weapon to help law enforcement officials solve any subsequent crimes committed by a person in possession of the firearm.

SUMMARY OF THE INVENTION




The present invention concerns a system for monitoring use of a weapon. The weapon includes a monitoring station and at least one weapon in which the weapon fires a projectile and includes a tracking device that receives navigational. The weapon also has a transceiver that transmits at least the navigational data to the monitoring station. In one arrangement, the weapon can include a biometric identifier for identifying a user and a trigger mechanism in which the biometric identifier can enable the trigger mechanism only when the biometric identifier identifies an authorized user.




The tracking device can be a global positioning system receiver that can receive navigational data from a plurality of global positioning system satellites. As an example, the navigational data can include global positioning system coordinates in which the coordinates can include at least a latitude coordinate, a longitude coordinate and an altitude coordinate. In another arrangement, the transceiver can transmit identifying information to the monitoring station, and the identifying information can include at least one of a name, an address and a physical description of a user of the weapon.




The weapon can also have a trigger mechanism, and the transceiver can receive a disabling signal for disabling the trigger mechanism. The disabling signal can be selectively transmitted from the monitoring station. In one embodiment, the trigger mechanism can include a trigger, and the disabling signal can disable the trigger mechanism by causing the trigger to be immobilized. Additionally, the trigger mechanism can include a latch in which the latch can immobilize the trigger by selectively engaging the trigger.




In one aspect of the invention, the weapon can further contain a camera for producing at least one of an audio and a video segment. The camera can be activated when the weapon fires a projectile, and the transceiver can transmit at least one of the audio and video segments to the monitoring station. In another aspect, the weapon can have at least one sensor mechanism in which the sensor mechanism can detect when the weapon fires a projectile and can generate a signal containing data indicating that the weapon has fired a projectile and when the weapon fired the projectile. The transceiver can transmit this signal to the monitoring station, and the at least one sensor mechanism can include a sonic sensor. The weapon can further have a trigger mechanism having a trigger, and the at least one sensor mechanism can be electrically coupled to the trigger and the sensor mechanism can generates the signal when the trigger is pulled.




In another arrangement, the biometric identifier can be a fingerprint verification device having a memory for storing digitized fingerprint images. The fingerprint verification device can generate digitized images of fingerprints and can compare the generated images with the fingerprint images stored in the memory to authorize use of the weapon. Moreover, the fingerprint verification device can have at least one fingerprint scanner on a handle of the weapon. The trigger mechanism can have a trigger and a latch selectively engageable with the trigger, and the biometric identifier can cause the latch to disengage the trigger when the biometric identifier identifies the authorized user. In another aspect, the weapon can include at least one sensor mechanism and a trigger mechanism in which the trigger mechanism can have a trigger and the sensor mechanism can have a pressure switch located on the trigger. The sensor mechanism can generate a signal when a user places a finger on the pressure switch on the trigger.




The present invention also concerns an intelligent weapon for firing a projectile. The weapon includes a tracking device in which the tracking device receives navigational data and a transceiver. The transceiver transmits at least the navigational data to a monitoring station. The intelligent weapon also contains several of the components listed above regarding the system for monitoring use of a weapon and interacts with one or more of the mechanisms described above as well.




DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIG. 1

, a system


100


for monitoring use of a weapon is shown. The system


100


can include at least one monitoring station


110


and at least one weapon


112


. As an example, the weapon


112


can be any device that can fire a projectile, such as a firearm. The weapon


112


can include a tracking device


114


that can receive navigational data and a transceiver


116


that can transmit at least the navigational data to the monitoring station


110


. In one arrangement, the transceiver


116


can transmit such data to the monitoring station


110


over a wireless communications link


118


. This wireless communications link


118


can be any suitable link for transmitting radio frequency (RF) signals from the transceiver


116


to the monitoring station


110


and vice-versa. For purposes of the invention, an RF signal can be any signal that can be wirelessly propagated through a suitable medium. The monitoring station


110


can also include a transceiver


117


for transmitting signals over the wireless communications link


118


to the transceiver


116


of the weapon


112


.




In one arrangement, the tracking device


114


of the weapon


112


can be a global positioning system (GPS) receiver that can receive the navigational data from a plurality of GPS satellites


120


. The GPS satellites


120


can communicate with the tracking device


114


of the weapon


112


over a satellite communications link


122


, which can be any link suitable for broadcasting RF signals from the GPS satellites


120


to the tracking device


114


. Of course, this satellite communications link


122


can also be used to transmit signals from the GPS satellites


120


to the monitoring station


110


and vice-versa or from the tracking device


114


to the GPS satellites


120


.




The navigational data can include GPS coordinates such as a latitude coordinate, a longitude coordinate and an altitude coordinate. As noted earlier, the transceiver


116


of the weapon


112


can transmit this navigational data to the monitoring station


110


, which can use these coordinates to track the location of the weapon


112


. Those of ordinary skill in the art, however, will appreciate that any other device or system suitable for providing location information to the tracking device


114


of the weapon


112


and capable of being forwarded to the monitoring station


110


can be used with the system


100


.




In one particular arrangement, the system


100


can employ differential GPS to produce more accurate readings. As is known in the art, differential GPS technology relies on a stationary GPS receiver with known GPS coordinates for correcting errors in the transmissions from GPS satellites to other stationary or mobile targets containing GPS tracking devices. As an example, a differential tracking device


124


can be built into the monitoring station


110


and can receive signals from the GPS satellites


120


over the satellite communications link


122


. The differential tracking device


124


, because its GPS coordinates have previously been accurately measured, can generate an error correction factor that can be used to error correct the transmissions from the GPS satellites


120


. The error correction factor can be transmitted from the transceiver


117


of the monitoring station


110


to the transceiver


116


of the weapon


112


over the wireless communications link


118


to produce a more accurate reading of the GPS coordinates of the weapon


112


.




It is understood, however, that the differential tracking device


124


is not limited to being positioned at the monitoring station


110


, as any number of differential tracking devices


124


can be placed at other suitable locations (as also illustrated in FIG.


1


). Moreover, the system


100


can be designed to rely on pre-existing differential tracking devices


124


constructed by, for example, a governmental agency. Nevertheless, the use of differential GPS is not a requirement of the invention; in fact, it must be stressed that the invention is not limited to tracking a weapon


112


through the use of GPS technology, as any other technique for locating the weapon


112


can be practiced with the invention.




Referring to

FIG. 2

, an example of a weapon


112


for use with the system


100


is illustrated. As an example, the weapon


112


can be a semi-automatic pistol that can fire any suitable number of projectiles or bullets. It is understood, however, that this illustration is merely one example of a weapon in accordance with the inventive arrangements and should not be construed to limit the invention. For example, the weapon


112


can also be a “stun gun,” a gun used to incapacitate persons through an electrical charge. In this example, the transmitted electrons can be considered projectiles. In one arrangement, the tracking device


114


and the transceiver


116


can be located in a handle


126


of the weapon


112


; these components can also be positioned in other suitable locations on the weapon


112


.




A portion of the weapon


112


is cut away to show a section of the weapon


112


typically covered by an outer shell


129


of the weapon


112


. As shown, the weapon


112


can include a trigger mechanism


128


. The trigger mechanism


128


can include a trigger


130


and a latch


132


that can selectively engage the trigger


130


. For purposes of clarity, only a portion of the trigger


130


is illustrated. As an example, the latch


132


can have an elongated shape, and the trigger


130


can include a slot


134


that can receive at least a portion of the latch


132


. In one arrangement, the latch


132


can be part of a solenoid


136


and can engage or disengage the trigger


130


through the slot


134


when the solenoid


136


receives a signal. Circumstances that would initiate a latch engaging or disengaging are discussed below.




If the latch


132


engages the trigger


130


through the slot


134


, the latch


132


can immobilize the trigger


130


, and a user will be unable to sufficiently pull the trigger


130


to cause the weapon


112


to fire a projectile. Conversely, if the latch


132


disengages the trigger


130


(by being removed from the slot


134


), the trigger


130


is no longer immobilized, and the user would be free to fire the weapon


112


. Those of ordinary skill in the art will appreciate that the above-described configuration is merely one example of how to selectively engage the weapon


112


, as any other suitable mechanism can be used to do so. For example, the weapon


112


can include a safety lever


138


, a component typically located on many firearms, in which the safety lever


138


can be selectively controlled through the use of the solenoid


136


.




The weapon


112


can also include a biometric identifier


140


. The biometric identifier


140


can be used to measure at least one biometric characteristic of a user. Implementing a biometric identifier


140


into the weapon


112


can prevent unauthorized use of the weapon


112


. As an example, the biometric identifier


140


can be a fingerprint verification device


142


having at least one fingerprint scanner


144


. In one particular embodiment and as shown in

FIG. 2

, the fingerprint scanner


144


can be located on the handle


126


of the weapon


112


to maximize convenience to the user. To easily accommodate right or left-handed users, a fingerprint scanner


144


can be placed on either side of the handle


126


. Of course, the invention is not so limited, as the fingerprint scanner


144


can be located at any other suitable position on the weapon


112


.




It is also important to note that the biometric identifier


140


is not limited to verifying a user's fingerprint. As such, the biometric identifier


140


can be a device that can analyze other suitable biometric measurements such as (but not limited to) a retinal scan, an iris scan or voice recognition. An example of a biometric identifier


140


in accordance with the inventive arrangements will be described below. In another arrangement, the weapon


112


can include at least one sensor mechanism


148


. The sensor mechanism


148


can detect when the weapon


112


fires a projectile and can generate a signal containing data that indicates that the weapon


112


has fired such a projectile and at what time the projectile was fired. Examples of a sensor mechanism


148


in accordance with the inventive arrangements will be described below.




The weapon


112


can also include a camera


150


that can produce an audio segment, a video segment or a combination of the two. Although

FIG. 2

illustrates the camera


150


as being disposed near the front of the weapon


112


below a barrel


152


of the weapon


112


, the invention is not limited to this particular configuration, as the camera


150


can be positioned at any other suitable location on the weapon


112


. In one embodiment, the camera


150


can be activated when the weapon


112


fires a projectile or when a user places his or her finger on the trigger


130


, at which time the camera


150


can begin to produce segments of audio and/or video. The transceiver


116


of the weapon


112


can subsequently transmit these segments of audio and/or video to the monitoring station


110


(see FIG.


1


).




Referring to

FIG. 3

, a block diagram illustrating a number of the components of the weapon


112


(represented by the dashed outline) described in relation to

FIGS. 1

and


2


is shown. In addition to each of the previously discussed elements, the weapon


112


can have a central microprocessor


154


for controlling the operation of the components of the weapon


112


. Specifically, the weapon


112


can include control and data interfaces for permitting the central microprocessor


154


to control the operation of the tracking device


114


, the transceiver


116


, the biometric identifier


140


, the solenoid


136


, the sensor mechanism


148


and the camera


150


. In addition, suitable software or firmware can be provided in memory for the conventional operations performed by the central microprocessor


154


; program routines can also be provided for the central microprocessor


154


in accordance with the inventive arrangements.




As noted earlier, the tracking device


114


can receive navigational data from, for example, GPS satellites


120


over the satellite communications link


122


and can forward the navigational data to the central microprocessor


154


. In accordance with GPS technology, the GPS satellites


120


can continuously update the navigational data, which can be particularly useful if the weapon


112


is in transit. The central microprocessor


154


can instruct the transceiver


116


to transmit this navigational data to the transceiver


117


of the monitoring station


110


over the wireless communications link


118


. The monitoring station


110


can have at least one display


156


for displaying this navigational data thereby permitting an operator or a computer at the monitoring station


110


to track the whereabouts of the weapon


112


.




As discussed earlier, the latch


132


may be engaged with the slot


134


of the trigger


130


, which can immobilize the trigger


130


. For convenience, only a portion of the trigger


130


of the trigger mechanism


128


is shown. Although

FIG. 3

implements the trigger


130


as shown in

FIG. 2

, it is important to note that the term “trigger” is not limited to a conventional firearm trigger commonly found on many guns. The term “trigger” can include any device, component or circuit capable of causing a weapon to fire a projectile.




If an authorized user wishes to use the weapon


112


, the user can provide a biometric sample, such as a fingerprint, to the biometric identifier


140


. The biometric identifier


140


can analyze the biometric sample to determine whether the user is an authorized user. If the user is an authorized user, the biometric identifier


140


can signal the central microprocessor


154


, which in turn can signal the solenoid


136


. When activated, the solenoid


136


can cause the latch


132


to disengage the slot


134


of the trigger


130


, which can permit the trigger


130


to be “pulled” for purposes of firing a projectile. Conversely, if the biometric identifier


140


does not recognize the provided biometric sample, no signal is forwarded to the solenoid


136


, and the trigger


130


can remain immobilized.




The sensor mechanism


148


can determine whether and when the weapon


112


has fired a projectile. In one arrangement, the sensor mechanism


148


can include at least two electrical contacts


158


,


160


. Electrical contact


158


can be positioned on the trigger


130


of the weapon


112


and electrically coupled to a controller


162


of the sensor mechanism


148


; electrical contact


160


can be positioned behind the electrical contact


158


and electrically coupled to the controller


162


as well. The controller


162


can have a clock (not shown) for generating time stamps.




If a user is authorized to use the weapon


112


, i.e., the trigger


130


is not immobilized, when the trigger


130


is pulled far enough to fire a projectile, the electrical contact


158


on the trigger


130


can contact the electrical contact


160


, which can, at least temporarily, create a closed circuit between the electrical contacts


158


,


160


, their electrical couplings and the controller


162


. In response, the controller


162


can generate a signal containing data indicating that the weapon


112


has fired a projectile and can insert into this signal a time stamp from the clock indicating when the projectile was fired. The controller


162


can forward the signal to the central microprocessor


154


, which can instruct the transceiver


116


to forward the information in the signal to the transceiver


117


of the monitoring station


110


over the wireless communications link


118


. Similar to the navigational data, the information indicating that the weapon


112


has fired a projectile and the time that the projectile was fired can be displayed on the display


156


of the monitoring station


110


.




The electrical contacts


158


,


160


, as shown in

FIG. 3

, can be spaced apart at a distance that would require a user to pull the trigger


130


far enough to fire a projectile to generate the signal to be forwarded to the central microprocessor


154


. Nevertheless, the electrical contacts


158


,


160


can be spaced apart at other suitable distances; specifically, this distance is not limited to a space expansive enough to cause the weapon


112


to discharge a projectile before a signal is generated by the closing of the circuit containing these contacts


158


,


160


.




In an alternative arrangement, the sensor mechanism


148


can include a pressure switch


164


positioned on the trigger


130


and electrically coupled to the controller


162


. In one arrangement, the pressure switch


164


can be located on the trigger


130


such that a user's finger will contact the pressure switch


164


when the user places his or her finger on the trigger


130


. The pressure switch


164


can detect this contact and can signal the controller


162


of the sensor mechanism


148


. The controller


162


can signal the central microprocessor


154


and as an option, can attach to this signal a time stamp from its clock. The central microprocessor


154


can instruct the transceiver


116


to transmit this information to the transceiver


117


of the monitoring station


110


over the wireless communications link


118


, and the information can be shown on the display


156


. Thus, a party at the monitoring station


110


can be aware that a user in possession of the weapon


112


has placed his or her finger on the trigger


130


in preparation of possibly firing the weapon


112


.




In addition to the previous two examples, the sensor mechanism


148


can also include a microphone


166


for detecting when the weapon


112


fires a projectile. The microphone


166


can capture the sound of the weapon


112


firing and can convert this sound into an electrical signal. The microphone


166


can forward this signal to the controller


162


, which in turn can add to the signal a time stamp from its clock and can send the signal to the central microprocessor


154


. As known in the art, the sensor mechanism


148


can include a filtering circuit (not shown) programmed to recognize the digital signature of the distinct sound that the weapon


112


produces when fired. Such a design can help eliminate false signals that may otherwise be misinterpreted as an indication that the weapon


112


has discharged a projectile.




Similar to the signals generated by the electrical contacts


158


,


160


and the pressure switch


164


, the central microprocessor


154


can instruct the transceiver


116


to transmit to the monitoring station


110


(over the wireless communications link


118


) the information contained in the signal produced by the microphone


166


. Those of ordinary skill in the art will appreciate that the sensor mechanism


148


is not necessarily limited to either of the above-described examples, as any other component capable of determining that the weapon


112


has fired a projectile (and optionally at what time the weapon was fired) can be implemented into the invention. Of course, the use of a sensor mechanism


148


is not required to practice the invention.




The camera


150


can produce segments of audio or video or a combination thereof. For purposes of the invention, the term “video” can include streaming video or a series of discrete photographs similar to those images produced by a digital camera. Thus, the camera


150


can be any camera capable of producing such video and because this technology is well known, a detailed explanation of this particular component is unnecessary. Nevertheless, it is important to note that the camera


150


can include a microphone


168


for capturing sound and converting the sound into electrical signals. It is also understood that the camera


150


can include a suitable encoding mechanism (not shown) for compressing any video and audio produced by the camera


150


.




Once compressed, the video and/or audio can be fed to the transceiver


116


, and the central microprocessor


154


can instruct the transceiver


116


to transmit the video and/or audio to the transceiver


117


of the monitoring station


110


over the wireless communications link


118


. As those of ordinary skill in the art will appreciate, the transceiver


116


can contain suitable circuitry for permitting the transmission of the video and/or audio over the wireless communications link


118


. Once received, the segments of video and/or audio can be shown or broadcast over the display


156


of the monitoring station


110


. As such, an operator at the monitoring station


110


can view images and listen to sounds associated with the environment in which the weapon


112


currently sits or is being handled.




The invention envisions several different scenarios for activating the camera


150


. For example, the camera


150


can be activated at all times such that the weapon


112


is constantly transmitting video and/or audio to the monitoring station


110


. Alternatively, the central microprocessor


154


can be programmed to activate the camera


150


at predetermined intervals, which can permit an operator to check the status of the weapon


112


through the generated video/audio segments at such intervals. In another arrangement, an activation signal can be transmitted from the transceiver


117


of the monitoring station


110


to the transceiver


116


of the weapon


112


over the wireless communications link


118


. Once it receives this signal, the transceiver


116


can signal the central microprocessor


154


, which can subsequently signal, and thereby activate, the camera


150


to begin producing segments of video and/or audio. This activation signal transmitted from the monitoring station


110


can be sent at any time, and the transmission can even be in accordance with a predetermined interval.




The camera


150


can also be activated based on the signals generated by the sensor mechanism


148


. For example, if the sensor mechanism


148


generates a signal based on the completion of the circuit including the electrical contacts


158


,


160


when the trigger


130


is pulled, the central microprocessor


154


can signal the camera


150


to begin producing video and/or audio. In addition, the central microprocessor


154


can signal the camera


150


in response to the central microprocessor's


154


receipt of the signals created by the sensor mechanism


148


through the pressure switch


164


or the microphone


166


. It is understood, however, that the invention is not limited to any of the above examples, as any other suitable mechanism for activating the camera


150


can be practiced with the invention.




In one arrangement, a disabling signal can be transmitted from the monitoring station


110


for remotely disabling the trigger mechanism


128


. Specifically, the disabling signal can be sent from the transceiver


117


of the monitoring station


110


to the transceiver


116


of the weapon


112


over the wireless communications link


118


. The signal can then be forwarded to the central microprocessor


154


, which, in response, can signal the solenoid


136


. This signal can energize the solenoid


136


thereby causing the latch


132


to engage the slot


134


of the trigger


130


. As explained earlier, this process can immobilize the trigger


130


thereby disabling the trigger mechanism


128


. If desired, the central microprocessor


154


can be programmed to grant this disabling signal with priority over any other signals processed by the central microprocessor


154


.




The weapon


112


can also include a power supply


170


. Although no connections are shown in

FIG. 3

for purposes of convenience, the power supply


170


can supply power to the tracking device


114


, the transceiver


116


, the biometric identifier


140


, the sensor mechanism


148


, the camera


150


, the central microprocessor


154


and any other components related to each of the above elements. In one arrangement, the power supply


170


can comprise a set of disposable or rechargeable batteries. Of course, any other suitable form of a portable power supply can be practiced with the invention. The weapon


112


can also include a power indicator light (not shown) that can inform a user that the power supply


170


needs to be replaced or recharged.




Referring to

FIG. 4

, one example of a biometric identifier


140


in accordance with the inventive arrangements is shown. In this example and as explained above, the biometric identifier


140


can be a fingerprint verification device


142


, which can be loaded with authorized, digitized images of fingerprints, can generate digitized images of fingerprints and can compare the generated images with the stored, authorized images for purposes of enabling the trigger mechanism


128


(see FIG.


3


). The fingerprint verification device


142


can include a biometric microprocessor


410


containing a memory


412


, of which at least a portion can be non-volatile, a platen


414


, a light source


416


, a fingerprint scanner


144


(see

FIG. 2

also) and a pressure switch


420


. In addition, the biometric microprocessor


410


can include a timer


422


.




The fingerprint verification device


142


can also include a port


424


coupled to the memory


412


of the biometric microprocessor


410


. Through this port


424


, digitized fingerprint images of authorized users can be uploaded into the memory


412


of the fingerprint verification device


142


. As an example, fingerprint scanning devices can be located at law enforcement agencies or authorized firearms dealers, who can verify that the individual whose fingerprint images are being generated for storage is permitted to own a weapon. Of course, other suitable individuals, agencies or organizations can be used to create fingerprint images for storage in the memory


412


of the fingerprint verification device


142


.




It is understood, however, that the invention is not so limited, as the fingerprint verification device


142


is not required to have a port for permitting the uploading of authorized fingerprint images. For example, the biometric microprocessor


410


can be programmed to initiate an authorizing step in which the fingerprint verification device


142


can permit a user to generate the authorized images himself or herself. Such a process would eliminate the need for any third parties to perform the authorization step, and the user could enter into the memory


412


any suitable number of approved fingerprint images.




The light source


416


can direct light towards the platen


414


and can be, for example, a light emitting diode. The platen


414


can also be transparent to the wavelength of the emitted light and can contain the pressure switch


420


, which can be electrically coupled to the biometric microprocessor


410


. The pressure switch


420


can detect when a user has placed his or her finger on the platen


414


and can signal the biometric microprocessor


410


. In addition, the biometric microprocessor


410


can control the operation of the light source


416


and the fingerprint scanner


144


. The fingerprint scanner


144


can be any biometric device capable of scanning fingerprint images and converting these images into digitized images.




In operation, a user can place his or her finger on the platen


414


, and the pressure switch


420


can signal the biometric microprocessor


410


. The biometric microprocessor


410


can signal the fingerprint scanner


144


and the light source


416


, which can emit the light needed to create a scanned image of the user fingerprint. The light can pass through the platen


414


and can strike the user's finger, which can cause the light to be reflected to the fingerprint scanner


144


.




From the reflected light, the fingerprint scanner


144


can generate a scanned image of the user's fingerprint and can convert the image into a digital signal. The fingerprint scanner


144


can forward this signal to the biometric microprocessor


410


, which can compare this generated image with the digitized images stored in the memory


412


. The biometric microprocessor


410


can signal the central microprocessor


154


(see

FIG. 3

) with the results of the comparison.




In particular, referring to

FIGS. 3 and 4

, if the newly generated fingerprint image matches an image stored in the memory


412


, the biometric microprocessor


410


can signal the central microprocessor


154


, which can signal the solenoid


136


to energize thereby causing the latch


132


to disengage the slot


134


. As explained earlier, this process can enable the trigger mechanism


128


by permitting the trigger


130


to be pulled to fire the weapon


112


. Conversely, if the generated image does not match an image stored in the memory


412


, the biometric microprocessor


410


can signal the central microprocessor


154


, which will not signal the solenoid


136


for purposes of enabling the trigger mechanism


128


.




In another arrangement, as authorized fingerprint images are loaded into the memory


412


, the central microprocessor


154


can be programmed with certain types of information related to the owner of the scanned fingerprint image. As an example, when a user has his or her fingerprint images scanned and loaded into the memory


412


, the central microprocessor


154


can be programmed with identifying information relevant to that user. For instance, the information can include the user's name, address and physical description. In addition, a digitized photograph of the user, compressed with any suitable compression technique, can be transferred into the memory


412


. It is understood, however, that the invention is not limited to these particular examples, as the central microprocessor


154


can be programmed with other suitable types of information concerning the user.




When the biometric microprocessor


410


determines that a scanned image matches an image stored in the memory


412


, the biometric microprocessor


410


can signal the central microprocessor


154


with a coded signal that can instruct the central microprocessor


154


as to which authorized user(s) has provided a fingerprint image. In response, the central microprocessor


154


can access the identifying information relevant to the user and can instruct the transceiver


116


to transmit the information to the transceiver


117


of the monitoring station


110


over the wireless communications link


118


. This identifying information can supplement the navigational data that is being transmitted to the monitoring station


110


or can be transmitted without the navigational data. When the identifying information is received at the monitoring station


110


, this information can be shown on the display


156


. As such, an operator at the monitoring station


110


can determine who has enabled the weapon


112


through the fingerprint verification device


142


.




In another arrangement, the fingerprint verification device


142


can enable the trigger mechanism


128


for a limited time interval. For example, once the biometric microprocessor


410


determines that the user is an authorized user and signals the central microprocessor


154


to enable the trigger mechanism


128


, the timer


422


can be used to limit the duration that the trigger mechanism


128


is enabled. Specifically, once the trigger mechanism


128


is enabled, the timer


422


can begin a countdown of a predetermined time interval. After the predetermined time interval is over, the timer


422


can signal the biometric microprocessor


410


, which can initiate another authorization step. If the user has kept his or her finger on the platen


414


of the biometric identifier


140


, another scanned image of the user's fingerprint can be created, and the biometric microprocessor


410


can once again compare this image to the stored images in the memory


412


. If there is a match, the trigger mechanism


128


can remain enabled.




Conversely, if the user has removed his or her finger from the platen


414


of the fingerprint verification device


142


and the predetermined interval has timed out, no image can be created, and the biometric microprocessor


410


can signal the central microprocessor


154


. The central microprocessor


154


can then signal the solenoid


136


, which can cause the latch


132


to engage the slot of the trigger


130


and disable the trigger mechanism


128


. This same principle can apply if an unauthorized user has acquired the weapon


112


and has placed his or her finger on the platen


414


. The predetermined interval can be any suitable duration of time.




Although one example of a biometric identifier has been presented, it is important to note that the invention is in no way limited to this particular system. Those of ordinary skill in the art will appreciate that other systems suitable for measuring biometric characteristics can be used. Examples of other suitable systems include retinal or iris scanners or voice recognition systems. In fact, the invention does not require the use of a biometric identifier, as the weapon


112


and the system


100


(see

FIG. 1

) can operate without such a device.




Although the present invention has been described in conjunction with the embodiments disclosed herein, it should be understood that the foregoing description is intended to illustrate and not limit the scope of the invention as defined by the claims.
