Firearm Event Detection via Sensor Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Law enforcement and security personnel face challenges in timely communication during firearm confrontations due to the need to maintain proper weapon handling, which limits their ability to use radio communication devices effectively.
Innovation Solution
A system comprising an Environmental Sensor Unit (ESU) mounted on a firearm, which includes sensors to detect and interpret events like discharge, manipulation, and environmental conditions, allowing for real-time data collection and transmission to a centralized dispatch, enabling enhanced situational awareness and communication of weapon status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If law enforcement personnel manually operate radio communication devices during firearm confrontations, then communication capability is improved, but weapon handling capability deteriorates
Solution Approach 1:
The system enables automatic weapon event detection and communication initiation without requiring manual operation by the officer. Sensors automatically detect weapon events (draw, fire, holster) and trigger communications, allowing the weapon system to serve its own monitoring and communication needs
Solution Approach 2:
Manual mechanical operation of radio devices is replaced with automated sensor-based detection and electronic communication systems. The physical manipulation of radio equipment is substituted with automated electronic sensing and wireless transmission
2Reliability
If law enforcement personnel focus on proper firearm handling during confrontations, then weapon safety is improved, but ability to establish communications deteriorates
Solution Approach 1:
The firearm handling system automatically monitors and communicates weapon status without requiring the officer to divert attention from proper weapon handling. The system serves itself by automatically detecting events and initiating communications
Solution Approach 2:
The system provides automatic feedback about weapon events to centralized dispatch, creating a closed-loop communication system where weapon status is continuously monitored and reported without requiring manual intervention from the officer
3Loss of information
If manual communication operations are performed during weapon confrontations, then communication capability is improved, but response time deteriorates
Solution Approach 1:
The system performs preliminary setup of sensors and automatic communication protocols before confrontations occur. When weapon events happen, the system is already configured to immediately detect and communicate, eliminating setup time during critical moments
Solution Approach 2:
Manual communication operations are replaced with automated sensor-based detection and electronic transmission, eliminating the time required for manual device operation and enabling immediate communication of weapon events

AI summary
Systems, devices, and methods, wherein a device is attachable to a firearm and includes a pressure sensor configured to sense pressure generated from the firearm and provide a corresponding signal, a weapon movement sensor configured to sense at least one movement of the firearm and provide a corresponding signal, at least one processor; and memory including computer instructions, the computer instructions configured to, when executed by the at least one processor, cause the at least one processor to determine an event of the firearm based on the corresponding signal provided by the pressure sensor and the corresponding signal provided by the weapon movement sensor. Systems that include the device may record event data and transmit the event data to various user systems for situational awareness, record keeping, training, and other organizational or legal-process purposes.
