Description

BACKGROUND

As of today, gun violence is a global issue without a good solution. Traditional gun violence mainly occurred in gang fighting or drug related crime. Most of the victims are gang members or drug dealers. The number of deadly victims per case is generally small. However, the situation had changed dramatically in recent years. Many gun violence cases target masses of innocent people; some of them even target young children or senior citizens. Meanwhile, the number of deadly victims per case has increased sharply. In the 2016 Florida gay club shooting, nearly 50 people died, plus another 50 people injured. The background of gunners varies from the mentally ill, to young students to terrorists. Many of them don't have any criminal or mental illness records and acquire the gun and ammunition legally. Although laws and regulations for strict gun control have been discussed for decades, little progress was made. Even though the new laws or regulations will be passed, considering the fact that there are over 300 million guns in the United States, enforcing the law is still a big challenge. It is time to address this problem from another angle, which is to control the ammunition. The presented patent presents a “smart ammunition” and its associated method, apparatus and system that requires a set of authorization procedures before the ammunition can be successfully fired. Without this procedure, the ammunition cannot be fired even it is loaded, for example, into a gun and the trigger is pulled.

DETAILED DESCRIPTION

FIG. 1 is a block diagram of an embodiment comprising generic guns (110), smart ammunition (115), local authorization servers (112, 113), optional smart device (120), local wireless network (119), authorization wireless network (117, 122), wireless antenna and wireless base stations (130), Internet (160, 165) and authorization server clusters (150). In one embodiment, without proper authorization, the propellant of the smart ammunition (115) will not ignite.

In one embodiment, the smart ammunition (115) has a wireless antenna and a wireless transceiver in it. Upon receiving wireless signals from the local authorization servers (112, 113), the smart ammunition (115) will periodically send out authorization requests to the local authorization servers (112, 113) with its unique identification number. Upon receiving the authorization requests from the smart ammunition (115), the local authorization servers (112, 113) will relay the requests through wireless network (117) to wireless base stations (130), then through Internet (160, 165) to authorization clusters.

In another embodiment, the local authorization server (112) communicates with a smart phone or other smart device (120) through local wireless network such as WiFi, Bluetooth, etc. The smart phone or other smart device (120) relays the request through wireless network (117) to wireless base stations (130), then through Internet (160, 165) to authorization clusters. The geographical location information is added during the authorization request rely process. This information can be added at multiple points. For example, if the local authorization servers (112, 113) have the optional GPS modules, they can add the geographical location information. If the smart phone or other smart device (120) has GPS module, it can add the geographical location information. The wireless base stations (130) can triangulate the requests and determine the rough location and add this information to the requests and send to the authorization server clusters (150). The authorization clusters (150) receive the authorization requests plus the associated geographical location information, evaluate the risk of the requests and decide if authorize the requests or deny the requests. The decisions are sent back through the same path to the smart ammunition (115). If the authorization requests are granted, the smart ammunition (115) will be armed. Upon the gun trigger is pulled, the firing pin hits the smart ammunition (115); its propellant will ignite (e.g., gun powder) inside the ammunition cartridge and drive the projectile (e.g., out a gun barrel). If the authorization requests are denied, the smart ammunition (115) will be disarmed; which means when the firing pin hits the smart ammunition (115), its propellant will not ignite.

In one embodiment, the risk evaluation process at the authorization server clusters (150) is a dynamic, multi-factor decision making process. For example, it will check if the geographical location of the request is too close to public school, transportation center, or other big public gathering. If so, the request will be denied. Local government, school or other organization can register with the authorization server clusters (150) and mark certain area during certain time period as public safety high risk zoom which the authorization server clusters (150) will deny any smart ammunition (115) authorization requests close to the zoom during the given period of time. After the event is over, the authorization requests at the given area can be granted. The authorization server clusters (150) can not only deny the authorization requests from the high risk zone, but also inform the law enforcement at the high risk zone regarding the requests so that proper actions can be taken to protect the public safety.

FIG. 2 is a block diagram of a smart ammunition according to an embodiment. It illustrates one possible embodiment of the smart ammunition using all active components. Unlike a traditional ammunition, the smart ammunition has a set of circuitry and mechanical mechanism to enable the firing authorization process and ensure the firing authorization grant or denial being executed cannot be comprised. In this embodiment, there is a small turn on/off (220, 222). One possible implementation is a small screw shape on/off switch illustrated in FIG. 4 (409, 425). They can be located at the projectile (220, 409), or located near the bottom of the cartridge (222, 425). In one embodiment, using a small screw driver to twist the small switch can turn on/off the smart ammunition. If the on/off switch of the smart ammunition is off, it cannot be fired. Upon turning on the smart ammunition, a battery (215) within the smart ammunition will power up all the active functional blocks of the smart ammunition, which include wireless transceiver (205), control unit (208), ignition circuitry (210), and striking sensor (212).

After control unit (208) initialization, in one embodiment it will periodically send an authorization request with its unique identification number through the wireless transceiver (205) and the wireless antenna (202) to the local authorization server (113, 112). The reason of periodically authorization is to make sure that authorization is only valid for a small amount of time, usually couple of minutes. To do so, we can limit or eliminate the risk of the smart ammunition authorized in a safe zone and later used in a risk zone. Upon receiving authorization grant reply from the local authorization server (113, 112), the control unit (208) will enable the striking sensor (212) unit. When the trigger of the gun is pulled, the striking pin hits the smart ammunition. The striking sensor (212) senses the striking; it will inform the control unit (208). The control unit (208) will enable the ignition circuitry (210) to ignite the propellant of the smart ammunition. If the control unit (208) of the smart ammunition receives the denial response, it will not enable the striking sensor (212) and the ignition circuitry (210) so that the propellant cannot ignite even when the striking pin of the gun hits the smart ammunition.

In one embodiment, the smart ammunition can permanently disable its firing capability upon receiving certain level of denial response from the authorization server. For example, trying to authorize a smart ammunition near public school or public transportation, the denial response may have the highest priority. It can cause the smart ammunition permanently disable its firing capability. At the authorization server clusters (150) side, these types of requests will be recorded and reported to public safety authority for further actions.

In one embodiment, many of the major parts (201) of the smart ammunition are installed inside the projectile, while a few of the smaller parts (218) may be installed inside the cartridge. In one embodiment, there may be a small set of thin wires connecting the projectile components with the components inside the cartridge. Upon propellant igniting, the high temperature may melt the thin wires and break the connection between projectile and the cartridge.

FIG. 3 illustrates a block diagram of the smart ammunition using passive authentication according to an embodiment. In this embodiment, an antenna (302) connects to a passive authorization unit (305). The antenna (302) collects the wireless energy sent by the local authorization servers (112, 113), and uses this energy to charge the passive authorization unit (305). After charging up, the passive authorization unit (305) will communicate with the local authorization servers (112, 113) to send out authorization request with its unique identification number. If the request is rejected, it will do nothing. If the request is granted, it will send out signal to turn on a battery (315) of the smart ammunition and wake up a control unit (308), a striking sensor (312), an ignition circuitry (310) and optionally an active wireless transceiver (309). The control unit (308) will enable the striking sensor (312) unit. When the trigger of the weapon is pulled, the striking pin hits the smart ammunition. The striking sensor (312) senses the striking; it will inform the control unit (308). The control unit (308) will enable the ignition circuitry (310) to ignite the propellant inside the smart ammunition. The propellant will drive the projectile out of the weapon.

In one embodiment, the grant from the passive authorization unit (305) only works for a short period of time. During this period of time, if the trigger is pulled, the smart ammunition will fire. After this period of time, the battery unit (315) is turned off. The local authorization servers (112, 113) have to charge it and authorize it again. It can prevent the smart ammunition being authorized at safe zone and be used at dangerous zone. If the optional active wireless transceiver (309) unit is presented, the control unit (308) can use it to send out authorization request to the local authorization servers (112, 113) when the grant period is passed instead of shut off the whole smart ammunition. If the new request is granted, the smart ammunition continues to be active; otherwise, it will shut off.

FIGS. 4A and 4B illustrate two possible embodiments of the smart ammunition. In both embodiments, an antenna is installed within the projectile (405) of the smart ammunition. In the embodiment (401) of FIG. 4A, a wireless transceiver, a control unit, an on/off switch, and a battery are installed within the projectile (407,409) of the smart ammunition.
