US12332005 - User authentication at an electromechanical gun

The present disclosure provides systems and techniques for authenticating a user at gun. The gun may include an authentication manager capable of implementing logic, processing signals, or executing instructions. The authentication manager may receive first query data from a first authentication sensor of the gun, receive second query data from a second authentication sensor of the gun, perform an authentication procedure to determine whether the first query data or the second query data matches enrollment data, where a match is determined based on the first query data or the second query data and the enrollment data satisfying a similarity threshold. The authentication manager may determine that the user is authorized to operate the gun and transmit a signal in response to the determining that the user is authorized to operate the gun. The signal may cause the gun to enter an active state which allows the gun to be fired.

The patent describes a firearm equipped with an authentication manager that verifies user identity through biometric data collected from multiple sensors, ensuring only authorized users can operate the gun. Upon successful authentication, the firearm can enter an active state, allowing it to be fired, while also incorporating ambient light measurements to enhance functionality.

Claim 1

A method for enrolling a user of a gun, the method comprising: receiving, from a first authentication sensor of the gun, first enrollment biometric data; receiving, from a second authentication sensor of the gun, second enrollment data; transforming the first enrollment biometric data into first transformed data; transforming the second enrollment data into second transformed data; generating a user profile for the user, the user profile comprising the first transformed data and the second transformed data; storing the user profile in non-volatile memory of the gun; receiving query biometric data from the first authentication sensor or the second authentication sensor; determining that the query biometric data corresponds to the user; producing a measurement of light at an ambient light sensor of the gun; and performing, based on the measurement of light, a function at a component of the gun in response to the determining that the query biometric data corresponds to the user. receiving, from a first authentication sensor of the gun, first enrollment biometric data; receiving, from a second authentication sensor of the gun, second enrollment data; transforming the first enrollment biometric data into first transformed data; transforming the second enrollment data into second transformed data; generating a user profile for the user, the user profile comprising the first transformed data and the second transformed data; storing the user profile in non-volatile memory of the gun; receiving query biometric data from the first authentication sensor or the second authentication sensor; determining that the query biometric data corresponds to the user; producing a measurement of light at an ambient light sensor of the gun; and performing, based on the measurement of light, a function at a component of the gun in response to the determining that the query biometric data corresponds to the user.
