Solution Overview
Problem
Existing methods for remotely disabling vehicles, such as mechanical devices and high-power microwave pulses, pose risks to bystanders and occupants due to lack of directivity and specificity, and may cause collateral damage.
Innovation Solution
A vehicle disabling apparatus that generates a high frequency signal modulated with a non-vehicle specific effects signals package, comprising pulse trains, to disrupt the engine management system of vehicles, allowing for remote engine disruption without prior knowledge of the vehicle type or model, using a narrow band microwave system to minimize harm to occupants and bystanders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high power broadband microwave/VHF source is employed to direct an electromagnetic pulse at a target vehicle, then the vehicle can be remotely disabled, but the broadband nature of the signal causes damage to vehicle and danger to occupants and bystanders
Solution Approach 1:
The patent applies local quality by using a narrowband microwave signal with specific frequency (e.g., 2.45 GHz) and controlled pulse characteristics that are tailored to interfere with electronic control units. The signal is localized in frequency spectrum and spatially directed using antenna arrays, affecting only the target vehicle's electronics while minimizing exposure to surrounding areas and protecting occupants from harmful broadband radiation.
Solution Approach 2:
The patent changes key parameters of the electromagnetic signal from broadband to narrowband, controlling frequency, pulse width, repetition rate, and power level. By adjusting these parameters, the system achieves reliable vehicle disabling through ECU interference while reducing harmful effects on occupants and bystanders. The signal parameters are optimized to target electronic systems specifically without causing thermal or physiological damage.
2Reliability
If a mechanical device is deployed in the path of a target vehicle to damage its tyres, then the vehicle can be stopped, but it is dangerous for personnel and difficult to position
Solution Approach 1:
The patent replaces the mechanical device approach with an electromagnetic signal-based system. Instead of deploying physical objects that require positioning in the vehicle's path, the system uses directed microwave signals that can remotely disable the vehicle's engine through ECU interference. This eliminates the need for personnel to position themselves in dangerous locations and removes the complexity of mechanical deployment while maintaining effective vehicle stopping capability.
3Reliability
If a high power broadband microwave/VHF source is employed to direct an electromagnetic pulse at a target vehicle, then the vehicle can be remotely disabled, but collateral damage may occur
Solution Approach 1:
The patent applies local quality by using a narrowband microwave signal with specific frequency and controlled pulse characteristics that are tailored to interfere with electronic control units. The signal is localized in frequency spectrum and spatially directed using antenna arrays, affecting only the target vehicle's electronics while minimizing exposure to surrounding areas and protecting occupants from harmful broadband radiation.
Solution Approach 2:
The patent converts the potential harm of electromagnetic radiation into a beneficial targeted effect by using narrowband signals that specifically interfere with electronic control units. The controlled pulse parameters and frequency selection ensure that the electromagnetic energy affects only the intended target's electronics while minimizing collateral damage to surrounding vehicles, infrastructure, and the environment.
