US12638258 - Method for activating and monitoring a firearm

A method for activating and monitoring a firearm system which tracks, monitors, and automatically prevents a firearm from firing when a user is not in a suitable state of mind or is not an authorized user. The firearm activation and monitoring system generally comprises a firearm having a trigger and grip area, a plurality of biometric sensors located on the grip area which measure biometric data of a user, a trigger interlock, and a main microcontroller. The trigger interlock prevents the trigger from firing the firearm when the trigger interlock is in its normal or default position. To unlock the trigger, the user holds the grip area to activate the biometric sensors, and if the user is in an acceptable mental state, the main microcontroller will send an electrical signal to the trigger interlock, which unlocks the trigger and allows the user to pull the trigger of the firearm.

US12292248 - Biometric firearm chamber lock

The biometric firearm chamber lock is a biometric electro-mechanical locking system integrated firearm safety device. The device safely locks firearms by securing the firearm lock into the firearm chamber through the ejection port to prevent rounds from being fired. An electrical biometric sensor quickly unlocks the firearm lock from the firearm. A mechanical backup unlock mechanism is used if a replacement battery is unavailable or if the electrical components fail and cannot be used to unlock the firearm lock. The firearm lock is an independent structure requiring no installation process.
