The techniques described herein relate to methods and apparatus for firearm safety mechanisms, visual safety indicators, and related techniques. A firearm includes a handle comprising one or more buttons disposed at least partially within a surface of the handle, such that the one or more buttons can be in contact with an operator's hand when the operator grasps the handle; a safety mechanism in mechanical communication with the trigger. The safety mechanism comprises: a first position that blocks actuation of the trigger; and a second position that does not block actuation of the trigger; and at least one processor configured to: upon determining an input code matches a stored code, transmits a signal to the safety mechanism to change the safety mechanism from the first position to the second position so that the firearm can be fired by the operator.

Systems, methods, and computer program products for detecting, locating, and identifying gunshots. In response to detecting a discharge of a firearm, a discharge alert indicating one or more characteristics of the discharge is transmitted to a gunshot location system. The one or more characteristics of the discharge are compared to one or more characteristics of one or more gunshots detected by the gunshot location system based on acoustic signals received at one or more listening stations. In response to finding a match between the one or more characteristics of the discharge and the one or more characteristics of acoustically detected gunshot, the gunshot is associated with the firearm.

A tracker for a firearm comprises a device capable of being secured to a Picatinny® rail of a firearm. The device is in wireless communication with a smart electronic device thereby alerting a user of when the firearm has been moved. The device also comes with an audio alert which issues forth a high decibel and painful sound to dissuade unauthorized use.

A reliable and robust electromechanical safety device maximises the security of a weapon by preventing accidental firing situations. The safety device includes a safety element for connecting or disconnecting a kinematic shooting chain; the safety element is arrangeable inside the weapon at its rear part, connecting with the trigger bar and the backstrap of the weapon. Therefore, by controlling the position of the trigger bar, it is possible to control the safe and firing position of the weapon, in addition to, and independent of, the other original weapon safeties.

A system for alerting a user to unauthorized movement of an object has a mat that is embedded with a first wireless transceiver (e.g., NFC transceiver) and a second wireless transceiver (e.g., Wi-Fi® transceiver). An object, such as a firearm, has a wireless tag (e.g., NFC tag) coupled thereto for communication with the first wireless transceiver of the mat. When the object is moved, the first wireless transceiver loses connection with the wireless tag. When communication is lost, the second wireless transceiver transmits an alert to a user that the object has been moved.

A smart gun communicating over a communication network. Wherein, the smart gun includes a triggering mechanism in order to lock/unlock the trigger for preventing/allow the gun to fire bullets, wherein the triggering mechanism is based on the information received from the GPS or the camera installed in the smart gun. Further, the safety system sends a message and/or GPS location of the smart gun over the communication network to the one or more concern authorities (i.e. law enforcement agency and/or the authorized user) in case the safety system detects any tamper to the safety gun.

An indication from a body-worn device may be received at a user device, in which the indication notifies the user device that the body-worn device has detached from a mounting position. The user device may be a body-worn hub or another body-worn device. A command is then generated at the user device to trigger the body-worn device or another body-worn device to perform an action based at least on the indication. In some instances, the user device may send an event notification for the indication to an event handler on a hub or a server for the event handler to determine whether to perform an action based at least on the event notification.

A smart round of ammunition includes a casing, a primer disposed at a bottom portion of the casing, a projectile mounted at a top portion of the casing and a propellant disposed within an interior portion of the casing between the projectile and primer. The primer includes a piezo generator transducing a mechanical force received at a firing pin portion of the primer into a stored charge, a switch coupling and decoupling a spark gap between the stored charge and the propellant, and a wireless sensor activating the switch responsive to a digital signal received from a component external to the casing. The activation permits a discharge of the stored charge into the spark gap and therefore detonates the propellant.

The present invention provides for systems, devices and methods for weapons modification to allow for use of real weapons in a simulated and augmented environment without exposing participants in the simulated and augmented training to risks of live ammunition. Embodiments of the invention provide an inexpensive and easily attachable/detachable appended system for the weapon which modifies or applies to a weapon in a simple fashion, and is capable of sensing necessary data for use in a simulated or synthetic training experience, and providing audio or tactile feedback to the firer, without rendering the weapon incapable of live fire use by simple detachment of hardware. Embodiments of the invention further provide an inexpensive and easily attachable/detachable weapon modification system that can provide all beneficial data capture, recording and transmission from a live fire weapon to either a simulated training system for processing, or other field use recording system.

Systems and methods are provided for weapon monitoring, including a weapon measurement system with one or more sensors that record longitudinal operational information of a plurality of weapons and are used to produce a plurality of signals, a connection point that receives the plurality of signals within a deployment location, a server device running application software that uses the plurality of signals received from the plurality of weapons to detect and store longitudinal situational state data of each weapon of the plurality of weapons, and a machine learning system that uses the longitudinal situational state data to calculate a weapon system failure state.
