US12747922 - Weapon usage monitoring system having real-time performance metrics feedback based on discharge event detection
This patent describes a system that monitors firearm performance by detecting discharge events through an inertial measurement unit (IMU) and calculating performance metrics, such as split times, in real-time. The results are communicated to users via augmented reality (AR) or virtual reality (VR) displays, allowing for performance comparisons between different users.
Claim 1
1 . A method for determining a performance metric based on a discharge event of a firearm, the method comprising: receiving, by a first event detection module associated with a first firearm of a first user, a plurality of first input signals over a sample window of time from a first inertial measurement unit (IMU) configured on the first firearm; identifying, by the first event detection module, an occurrence of a first shot discharge of the first firearm at a first time based on the plurality of first input signals, identifying, by the first event detection module, an occurrence of a second shot discharge of the first firearm at a second time based on the plurality of first input signals; and determining a first split time for the first user based on a difference between the first and second times; determining a performance metric, including the first split time, based on the identifying; communicating the performance metric to a user of the firearm in real-time, the communicating including displaying the performance metric on a user display comprising one of an augmented reality (AR), a virtual reality (VR) device and an integrated visual augmentation system (IVAS); receiving, by a second event detection module associated with a second firearm of a second user, a plurality of second input signals over a sample window of time from a second IMU configured on the second firearm; identifying, by the second event detection module, an occurrence of a first shot discharge of the second firearm at a first time based on the plurality of second input signals; identifying, by the second event detection module, an occurrence of a second shot discharge of the second firearm at a second time based on the plurality of second input signals; determining a second split time for the second user based on a difference between the first and second times; comparing the first split time of the first user to the second split time of the second user; ranking a performance of the first user relative to the second user based on the comparing; and displaying the ranking on the user display. receiving, by a first event detection module associated with a first firearm of a first user, a plurality of first input signals over a sample window of time from a first inertial measurement unit (IMU) configured on the first firearm; identifying, by the first event detection module, an occurrence of a first shot discharge of the first firearm at a first time based on the plurality of first input signals, identifying, by the first event detection module, an occurrence of a second shot discharge of the first firearm at a second time based on the plurality of first input signals; and determining a first split time for the first user based on a difference between the first and second times; determining a performance metric, including the first split time, based on the identifying; communicating the performance metric to a user of the firearm in real-time, the communicating including displaying the performance metric on a user display comprising one of an augmented reality (AR), a virtual reality (VR) device and an integrated visual augmentation system (IVAS); receiving, by a second event detection module associated with a second firearm of a second user, a plurality of second input signals over a sample window of time from a second IMU configured on the second firearm; identifying, by the second event detection module, an occurrence of a first shot discharge of the second firearm at a first time based on the plurality of second input signals; identifying, by the second event detection module, an occurrence of a second shot discharge of the second firearm at a second time based on the plurality of second input signals; determining a second split time for the second user based on a difference between the first and second times; comparing the first split time of the first user to the second split time of the second user; ranking a performance of the first user relative to the second user based on the comparing; and displaying the ranking on the user display.
