Dynamic Geofence Modification for Exited Occupant Threat Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current perimeter breach detection systems for vehicles are not dynamic enough to adapt to the changing environment and often result in false positive notifications, failing to effectively protect first responders who may be distracted or in varying situations.
Innovation Solution
A system that dynamically modifies the electronic geofence around a vehicle in response to an occupant exiting, using a combination of 360-degree light imaging and radio wave distancing systems to create a secondary geofence, ensuring effective threat detection and minimizing false notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed and/or pre-configured perimeter is established for threat detection, then the system can detect perimeter breaches, but it produces false positive notifications and cannot adapt to dynamic vehicle environments and varying situations
Solution Approach 1:
The patent applies dynamics by making the geofence perimeter adjustable and reconfigurable in real-time. The system transitions from fixed pre-configured perimeters to dynamic perimeters that can be modified based on detected threats, vehicle motion, and environmental factors. This allows the perimeter to adapt to varying situations while maintaining reliable threat detection.
Solution Approach 2:
The system changes perimeter parameters (size, shape, position) dynamically based on detected conditions. When a threat is detected or the vehicle moves, the geofence parameters are adjusted to maintain appropriate monitoring zones. This parameter adaptation resolves the contradiction between maintaining reliable detection and adapting to dynamic environments.
2Reliability
If the geofence is made large enough to cover all possible areas, then all potential threats can be detected, but false positive notifications increase and the system becomes less useful
Solution Approach 1:
The geofence dynamically adjusts its size and scope based on real-time conditions. When threats are detected, the perimeter expands to cover relevant areas; when no threats are present, it contracts to reduce false positives. This dynamic adjustment maintains adequate coverage while minimizing harmful false notifications.
Solution Approach 2:
The system applies different geofence configurations to different spatial zones and situational contexts. Rather than using a uniformly large perimeter, the geofence adapts its local boundaries based on where threats are detected and what the operational context requires. This localized adaptation provides sufficient coverage without generating excessive false positives.
3Object-generated harmful factors
If the geofence is made small to reduce false positives, then false notifications decrease, but the system may miss actual threats in varying environments
Solution Approach 1:
The geofence size is dynamically adjusted based on detected threats and environmental context. When the system detects potential threats or high-risk conditions, it expands the perimeter to ensure adequate coverage. When conditions are safe, it contracts to minimize false positives. This dynamic behavior ensures both reduced false positives and maintained threat detection reliability.
4Reliability
If the system continuously monitors and adjusts the geofence based on occupant location, then protection for exited occupants is improved, but device complexity increases
Solution Approach 1:
The geofence system serves multiple functions: it protects occupants inside the vehicle, tracks exited occupants, and provides threat detection. By making the geofence multi-functional and adaptable to different scenarios, the system provides comprehensive occupant protection without requiring entirely separate systems for each function, thereby managing complexity through consolidation.

AI summary
A process for dynamic vehicular threat detection perimeter modification for an exited vehicular occupant includes prior to detecting a vehicular occupant exiting the vehicle, establishing a first sized vehicular geofence surrounding the vehicle as a function of one or more stored vehicular perimeter distances. The first sized vehicular geofence is monitored for a first breach via one of a 360 degree vehicular light imaging and radio wave distancing system. In response to detecting that the vehicular occupant previously inside the vehicle has exited the vehicle, the one or more stored vehicular perimeter distances is modified as a function of a detected location of the exited vehicular occupant to establish a second sized vehicular geofence surrounding the vehicle different than the first sized vehicular geofence. The second sized vehicular geofence is monitored for a second breach via one of the 360 degree vehicular light imaging and radio wave distancing system.
