Description:
REFERENCE TO RELATED APPLICATIONS 
     This application is based on, and claims the benefit of, U.S. provisional patent application 62/608,823 filed Dec. 21, 2017, the contents of which are incorporated herein by reference. 
    
    
     BACKGROUND OF THE INVENTION 
     This invention relates to firearms; and, more particularly, a “smart” gun having a variety of capabilities which provide police and other law officers significant advantages when dealing with volatile situations. 
     With advances in modern technology, numerous features which were previously unavailable to firearm manufacturers are now available. These new features are particularly relevant when it comes to weaponry used by law enforcement personnel. The incorporation of these features particularly into the sidearms carried by police, and others, not only make them better able to carry out their duties, but also help in keeping them safe while doing so. The new technology makes it easier to determine an officer&#39;s exact location at all times, allows the officer to directly communicate with his partner manning a squad car or with a police dispatcher; and, in real time, enable the recordation and transmittal of actions occurring whenever the officer has to draw his weapon and ready it for use. 
     Most police officers now carry automatic handguns rather than pistols. Accordingly, it would be helpful to incorporate the technology now available into such weapons so they can be carried by police officers while serving in the line of duty. 
     BRIEF SUMMARY OF THE INVENTION 
     The present disclosure is directed to a firearm in which is integrated numerous features, now available because of advances in technology, useful to policemen and other law enforcement persons to enable them to better protect those whom they serve. The technology now incorporated in a firearm of the present invention includes a global positioning system (GPS) that enables an officer&#39;s exact location to be known at all times while on duty. Next, the weapon includes a transmitter and receiver that allows the officer to directly communicate with his partner manning a squad car, or with other officers in the area, or with a police dispatcher, all in real time. This is especially important in dangerous situations which have required the officer to draw his weapon. Further, the advanced firearm of the present invention also includes a camera to enable real time recordation and transmittal of events occurring at the location where the officer has had to draw his weapon and ready it for use. 
     Other objects and features will be in part apparent and in part pointed out hereinafter.

     DETAILED DESCRIPTION OF INVENTION 
     The following detailed description illustrates the invention by way of example and not by way of limitation. This description clearly enables one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what is presently believed to be the best mode of carrying out the invention. Additionally, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or carried out in various ways. Also, it will be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. 
     Referring to  FIG. 1 , a firearm of the present invention is indicated generally F. Firearm F is, for example, a sidearm carried by a policeman or other law enforcement official. Typically, when the firearm is holstered, a safety switch S on the side of the weapon is set to an “off.” or “safety” position meaning that the weapon will not discharge if one were to attempt to pull the weapon&#39;s trigger. If weapon F is an automatic firearm, ammunition for the weapon is loaded into a clip C which is inserted into the firearm through a slot (not shown) in the base of the weapon&#39;s handle H. Those skilled in the art understand that, if circumstances warrant, the police officer places his hand on handle or grip H to withdraw the weapon from its holster L, see  FIG. 2 , to aim or point the weapon at a target. Those skilled in the art further understand that if the firearm is a revolver, the weapon&#39;s ammunition is loaded into chambers in a cylinder that revolves when the officer cocks a trigger to bring a round of ammunition into a position to be fired when the trigger is pulled. 
     Almost all of the time an officer is on duty, firearm F remains holstered in its holster L with safety switch S in its “off/safe” position. Only in rare instances will an officer feel that a situation is so potentially dangerous that he needs to un-holster his weapon; and, even then, in most instances he will leave the weapon&#39;s safety “off/safe” position. If, however, the officer releases safety switch S so that the safety switch is moved from “off/safety” to “on/fire”, the officer is then able to discharge the weapon by pulling on its trigger T. Those skilled in the art will recall that some weapons are designed that any safety mechanism built into the weapon automatically switches from off/safe to on/fire when the weapon is withdrawn from its holster. Further, some weapons are designed to have no safety mechanism at all, so the weapon is always ready to fire. 
     Firearm F of the present invention incorporates a number of features to assist the officer in dangerous situations. 
     First, a camera CAM is mounted on the underside of the weapon&#39;s frame E beneath the front or muzzle end of the weapon, as shown in  FIG. 1 . Camera CAM acquires real time video imagery which is transmitted over a bi-directional communications link L 1  to the officer&#39;s vehicle V or a bi-directional communications link L 2  to a central dispatcher location D, or to another designated location. At each location V and D, the imagery is recorded for future use. 
     Next, firearm F is equipped with a microphone MIC which captures the officer&#39;s voice and other sounds and background noises, all in real time. The audio is also transmitted over respective links L 1  and L 2  to police vehicle V, dispatcher location D, or other designated location. 
     In  FIG. 1 , it will be noted that there is also a bi-directional communication link L 3  between vehicle V and dispatcher location D. While communications over this third link are not directed from or to firearm F, this link is important because it allows the officer&#39;s partner in the vehicle, or an area adjacent the officer&#39;s location, and the dispatcher, to communicate directly with each other in order to aid the officer. 
     Transmission of video and audio is accomplished using a transmitter XMT incorporated in the frame of firearm F. In addition to the transmitter, a receiver RCV is also incorporated in the frame. Receiver RCV includes a speaker K. The transmitter and receiver are equipped with Bluetooth® or other communications protocol which facilitates two-way communications between sites. 
     While police vehicles V are equipped with a global positioning system GPS, once the officer leaves the vehicle, he may not be readily tracked. For this reason, firearm F is equipped with a GPS unit built into its frame. The unit not only allows the officer&#39;s location to be reported to his vehicle and the dispatcher; but, in the unlikely event the officer loses his weapon or it is taken away from him, its location is readily known so that it can be tracked down and recovered. 
     In the course of the officer&#39;s duties, the above described devices are all activated when the officer draws the firearm from its holster L and moves safety switch S to its “on/fire” position. 
     Finally, all of the above described devices are powered by a battery B mounted in the firearm. Battery B is a lithium or other long term battery having a sufficient capability to power all of the above described devices for long periods of time regardless of the environment (hot, cold, damp, etc.) in which the firearm may be found in the officer&#39;s exercise of his duties. Battery B can also be readily replaced if necessary or required. 
     As shown in  FIG. 2 , a holster L in which the officer carries his firearm F includes a battery charger BC. When the firearm is holstered, battery charger BC is connected to battery B by a charging line CL incorporated in the firearm&#39;s handle H to keep battery B fully charged so none of the devices loses battery power when the firearm is in use. 
     In view of the above, it will be seen that the several objects and advantages of the present disclosure have been achieved and other advantageous results have been obtained.
