Disclosed herein are apparatuses, systems, methods, and machine readable media for activating a portable camera in response to the activity of a firearm, and for implementing and using a system for identifying an individual who discharged a firearm, and for recording, assessing, identifying, and transmitting information related to the firing of a firearm, and for monitoring the status of an implement at a mount, and for using a charging device for delivering electrical power to components of a firearm. A communications channel may be established between a firearm telematics sensor and a video camera, sometimes by means of intermediary devices. A communications channel may be established between a mount (e.g., holster) telematics device and local and/or remote monitoring service components, sometimes by means of intermediary devices. When the telematics sensor detects that its associated firearm is removed from its holster, or in motion, or being discharged, it may signal the camera to initiate recording. When the telematics device detects that its associated firearm is removed from its holster, the change in status can be reported to the local and/or remote system.

Devices, apparatus, systems and methods for locking ratchet belts about handguns and long guns with a ratchet belt and locking box. An embodiment can remove the working magazine from pistols and long guns replacing it with a non-working magazine that is locked onto the firearm. Another embodiment locks the trigger of handgun and long gun firearms. Another embodiment locks the firearm to support surfaces such as a wall, and the like. A still another embodiment can lock and prevent the pull handle of a shot gun from being pumped. Embodiments can be used alone or in combination so that handguns and long guns are locked and prevented from being discharged.

Child safety weapon locks are disclosed. The child safety weapon lock includes a detente housing, a locking shaft assembly, and a radial lever. The locking shaft assembly is engaged with the detente housing. The radial lever is engaged with the detente housing and selectively engaged with the locking shaft assembly. The radial lever selectively captures the locking shaft assembly between the radial lever and the detente housing.

A sensor system for a firearm is disclosed. The sensor system contains a body, a mounting facility adapted to mount the body to the firearm, a first accelerometer connected to the body operable to generate a first acceleration signal based on detected acceleration of the body, a second accelerometer connected to the body operable to generate a second acceleration signal based on detected acceleration of the body, the first accelerometer operable for detection of accelerations within a first range between a first lower limit and a first upper limit, the second accelerometer operable for detection of accelerations within a second range between a second lower limit and a second upper limit, the first lower limit being less than the second lower limit, and the first upper limit being less than the second upper limit, such that at least portions of the first range and the second range do not overlap.

An internal firearm locking mechanism includes a block that fits within the action of a firearm, and a lock that is removably secured to the block and passes into the chamber of the firearm to resist insertion of a cartridge as well as removal of the block. An installation/removal tool is used to install and remove the internal firearm locking mechanism.

An air gun, a removable magazine for an air gun, and associated methods. The air gun includes a safety mechanism that in a safety-on position prevents the trigger from actuating the firing mechanism and closes the gas supply duct, and in a safety-off position enables the trigger to actuate the firing mechanism and opens the gas supply duct to enable actuating the firing mechanism with compressed gas to fire a projectile. The removable magazine includes, a projectile feeder, a cavity for a gas canister, a push valve for selectively releasing pressurized gas from the gas canister, and a valve actuator. The valve actuator includes a socket that releasably receives a nipple of a gas supply coupling carried by an air gun, forms a seal with the nipple, and opens the aerosol valve when coupled with the gas supply coupling.

In certain embodiments, a trigger assembly including a bi-stable switch system configured to selectively engage a portion of the sear in a first state and to transition from the first state to a second state to selectively disengage the portion of the sear in response to an electrical signal.

This invention provides a discharge preventer assembly for a firearm that is a supplemental safety attachment for a firearm. The discharge preventer assembly can be made of a left body portion and a right body portion which can be adapted to connect to each other in a protective condition to collectively receive and enclose a trigger bow and a trigger; and at least one of the left body portion and the right body portion having a bolt block element protruding upward and adapted to be received in the bolt passage when the left body portion and the right body portion are in the protective condition. The discharge preventer assembly can also include one or more rigid plates configured to be positioned adjacent the right body portion or the left body portion.

This disclosure describes embodiments of an apparatus which will be called a bolt hold open, fire selector and safety. This apparatus is for ambidextrously holding open the bolt of a Kalashnikov style firearm; for ambidextrously selecting whether the Kalashnikov style firearm will fire multiple rounds or a single round each time the user pulls and holds down the trigger on the firearm when the firearm contains an auto sear mounting pin; for ambidextrously selecting whether the Kalashnikov style firearm will fire a single round each time the user pulls and holds down the trigger on the firearm when the firearm does not contain an auto sear mounting pin; and for ambidextrously selecting whether the Kalashnikov style firearm will fire when the user pulls the trigger on the firearm.
