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.

The invention describes a system for or recording the usage of a firearm and helping a user during usage of the firearm using multiple sensors to gather various information. The system includes a plurality of sensors to record various usage and status data of the firearm. The system further includes a communication module communicatively coupled to the sensors. The communication module is further connected to a processor. The system further includes a memory, a clock chip and an information disseminating device that includes a communication port. The plurality of sensors are configured to gather various information about a firearm device that may be a pistol, a revolver, a gun, etc. after being attached to the firearm device. In addition to the operational information, some of the sensors out of the plurality of sensors may gather information about surrounding environment of the firearm like lighting conditions, wind flow etc. to help a user of the firearm device to use it efficiently.

A safety device for a firearm provided with a grip and having a latch operated by a motor and adapted to be engaged with mechanical parts of the firearm to prevent and/or allow activation of the firearm is provided. A control unit connected to the motor and supplied by at least one battery has an internal transceiver cooperating with an external transceiver for controlling the latch by an authorized user. A capacitive sensor, operatively connected to the control unit for controlling the latch, is adapted to detect presence of a hand of an authorized user on the grip.

A device including a body coupled to a magazine receiving area of a firearm and a locking unit that locks a firearm to the body of the device.

The present disclosure relates to the technical field of special locks. The lock structure with improved safety includes a support assembly, a fixed cavity and an unlocking cavity; the fixed cavity is provided with a lock beam; the unlocking cavity is provided with a lockhole and a locking device; the lock beam is threaded into a trigger position of a gun and then into the lockhole and is locked by the locking device; an inner wall of the lockhole extends into the unlocking cavity to form a lockhole ring; a convex rib is arranged on an inner wall of the lockhole ring; a groove is formed in an outer wall of the lock beam; the convex rib and the groove are connected with each other in an embedded manner, so that the lock beam is stabilized in the lockhole ring.

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.

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 relates to a firearm safety control system. The system is primarily comprised of at least one camera, at least one image recognition software, at least one artificial intelligence software, and at least one disabling mechanism. Using the camera, the image recognition software detects and classifies a target. The artificial intelligence software then determines what lethality mode the target can be engaged at. If a user attempts to engage an area of the target not permitted by the current lethality mode, the firearm will become disabled and will not fire.

Apparatus and associated methods relate to a firearm lock configured to release a self-hardening interlock fluid into a firing chamber of a firearm in response to a predetermined force. In an illustrative example, the firearm lock may include an engagement module configured to releasably couple to a firing chamber of the firearm. In a locked mode, for example, the engagement module may prevent the firearm from firing. The firearm lock may include, for example, a tamper interlock module containing interlock material (IM) in a fluid state. When a predetermined force is applied to the tamper interlock module, for example, the IM may be dispensed from the cavity into the firing chamber and the IM may at least partially transition into a solid state such that the IM prevents the firearm from firing. Various embodiments may advantageously disable a locked firearm in response to tampering with the lock.

The present disclosure provides systems and techniques for determining whether a user is holding a gun. The gun may include a sensor, such as a laser proximity sensor, a capacitive proximity sensor, a load cell, an accelerometer, or a biometric sensor, and the gun may determine whether a user is holding the gun based on an output generated by the sensor. A processor housed in the gun may identify activation of a proximity sensor, determine that a user is holding the gun based on the activation of the proximity sensor, and perform an action in response to determining that the user is holding the gun. The action performed by the processor may include performing a boot procedure, performing a health check procedure, visually indicating state information about the gun, audibly indicating state information about the gun, or tactilely indicating state information about the gun.
