Solution Overview

Problem

Current mobile tracking devices, such as infrared-based systems, tend to approach and potentially contact assets, posing a threat, and existing countermeasures are either device-specific or ineffective against imaging and non-imaging detection systems.

Innovation Solution

A modulation device equipped with a continuous wave laser system that directs optical energy at mobile tracking devices to create localized sources within their field of view, confusing their detection systems and causing them to divert from the asset, without requiring specific optical codes or knowledge of the tracking device's modulation scheme.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If infrared hot bodies (flares) are used to misdirect mobile tracking devices, then the tracking device is diverted away from the asset, but the device complexity increases and the solution is only effective against specific types of tracking devices

Engineering Contradiction:
Improvetracking device diversionVSAvoidcountermeasure device complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces physical infrared hot bodies (flares) with an optical projection system that uses a light source and optical elements to project artificial infrared signals. This substitution eliminates the need for physical flare deployment mechanisms while achieving the same misdirection effect through projected optical patterns that mimic asset infrared signatures.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The optical projection system is designed to generate multiple different optical patterns corresponding to different asset types (vehicles, personnel, equipment). By storing multiple pattern sets in memory and selecting appropriate patterns based on detected asset characteristics, the system provides universal protection against various tracking device types without requiring separate countermeasure systems for each asset category.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If device-specific countermeasures are used, then the solution is tailored to specific tracking devices, but the adaptability to different detection systems (imaging and non-imaging) is reduced

Engineering Contradiction:
Improvecountermeasure effectivenessVSAvoiddetection system coverage
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts its optical pattern generation based on real-time detection of tracking device characteristics. The control circuit analyzes signals from sensors to identify whether an imaging or non-imaging detector is present, then adjusts the projected optical patterns accordingly. This dynamic adaptation allows the system to maintain high reliability across different detection system types without requiring pre-programmed device-specific configurations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes key parameters of the projected optical patterns including intensity, wavelength distribution, and spatial configuration based on the detected tracking device type. For imaging detectors, the system projects patterns that create false thermal signatures, while for non-imaging detectors, it projects patterns that overwhelm the sensor's detection capabilities. These parameter adjustments enable effective countermeasures against diverse detection systems using a single adaptable platform.
