Autonomous Search Light Tracking Using RF Target Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Human operators face challenges in directing and maintaining illumination of targets in dark environments, especially during search and rescue operations, due to difficulty in visually identifying and tracking moving targets with existing search lights.
Innovation Solution
An autonomous search light system equipped with an RF receiver and antennas that determines the position of an RF transmitter and adjusts the light output direction, intensity, and focus autonomously, allowing continuous illumination without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a human operator manually directs the search light towards a target, then the light output can be adjusted towards the target, but it is difficult to see and identify the target in dark environments without illumination
Solution Approach 1:
The system uses RF signals from the transmitter as feedback to automatically determine target position and adjust the search light direction, eliminating the need for manual visual targeting in dark environments
Solution Approach 2:
The autonomous search light system performs self-adjustment by automatically tracking the target using RF signal position data, without requiring continuous manual intervention from the operator
2Reliability
If the search light output is continuously adjusted to compensate for target movements, then the target remains illuminated, but this leads to a high level of operator activity
Solution Approach 1:
The system autonomously tracks moving targets by continuously monitoring RF signal position data and automatically adjusting the search light direction, eliminating the need for constant manual operator intervention
Solution Approach 2:
The patent replaces manual mechanical adjustment of the search light with an automated electronic control system that uses RF position data to drive motors and adjust the light direction automatically
3Illumination intensity
If traditional search lights are used in dark environments, then illumination can be provided, but the target cannot be easily identified or tracked without visual contact
Solution Approach 1:
The system performs preliminary detection using RF transmitters before illumination is needed, allowing the target to be located and tracked even in complete darkness where visual detection would be impossible
Solution Approach 2:
The patent introduces RF transmitters as an intermediary detection mechanism that enables target location independent of visual conditions, bridging the gap between detection and illumination functions
