Smart guns are commonly used in science fiction, where they may not only have biometric identification, but also have auto-aiming capabilities or smart bullets. A prominent example is the Lawgiver used by Judge Dredd, which is linked to his DNA. [29] Another is the M56 Smart Gun from Aliens, which is carried via a waist-mounted robotic arm.
A binary trigger (or pull and release trigger) is a type of device that allows a semi-automatic firearm to fire at an increased rate. A binary trigger works by firing one shot upon pulling the trigger and then firing a subsequent shot upon release of the trigger. Binary triggers are installed through modification of the fire-control group.
Biofire is beginning to ship its biometric “smart gun,” which uses fingerprint and facial recognition technology. Now the $1,499 handgun faces a test: Will it work?
A forced reset trigger (or "hard reset" trigger) is a device that allows a person to fire a semi-automatic firearm at an increased rate. The forced reset trigger works by mechanically resetting the trigger's position after a shot is fired. This allows for an increased rate of fire.
Firearms use triggers to initiate the firing of a cartridge seated within the gun barrel chamber.This is accomplished by actuating a striking device through a combination of mainspring (which stores elastic energy), a trap mechanism that can hold the spring under tension, an intermediate mechanism to transmit the kinetic energy from the spring releasing, and a firing pin to eventually strike ...
Biometric spoofing is a method of fooling [7] a biometric identification management system, where a counterfeit mold is presented in front of the biometric scanner. This counterfeit mold emulates the unique biometric attributes of an individual so as to confuse the system between the artifact and the real biological target and gain access to ...
A disassembled Mauser action showing a partially disassembled receiver and bolt. In firearms terminology and law, the firearm frame or receiver is the part of a firearm which integrates other components by providing housing for internal action components such as the hammer, bolt or breechblock, firing pin and extractor, and has threaded interfaces for externally attaching ("receiving ...
A smart lock is an electromechanical lock that is designed to perform locking and unlocking operations on a door when it receives a prompt via an electronic keypad, biometric sensor, access card, Bluetooth, or Wi-FI from a registered mobile device. These locks are called smart locks because they use advanced technology and Internet ...
