Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile gas leak detection methods face challenges in distinguishing leaks from background gas levels, differentiating leaks from other sources of measured gas, and estimating the distance to the leak source.
Innovation Solution
The approach involves automatic horizontal spatial scale analysis to differentiate leaks from background levels, using isotopic ratios and chemical tracers for source identification, and multi-point measurements for distance estimation, which can be combined for effective leak detection and localization.

1Area of stationary object
If conventional mobile gas leak detection methods are used, then gas leak detection can be performed over a large region, but difficulty in distinguishing a leak from background gas levels occurs
Solution Approach 1:
The patent applies local quality by analyzing the spatial scale characteristics of gas concentration variations at different locations. By examining whether concentration changes occur over small or large horizontal distances, the system distinguishes local leak signatures from broad background variations, enabling precise leak detection across large regions.
Solution Approach 2:
The patent introduces a new dimension of analysis by examining the horizontal spatial scale of concentration variations. Instead of merely measuring concentration magnitude, the system analyzes how concentration changes across space, adding a spatial scale dimension that enables differentiation between leaks and background gas levels.
2Area of stationary object
If conventional mobile gas leak detection methods are used, then gas leak detection can be performed over a large region, but difficulty with distinguishing a leak from other possible sources of the measured gas occurs
Solution Approach 1:
The patent uses local quality by analyzing the spatial scale characteristics of gas concentration variations. By examining whether concentration changes occur over small or large horizontal distances, the system distinguishes local leak signatures from broad background variations, enabling precise leak detection across large regions.
Solution Approach 2:
The patent introduces spatial scale analysis as an intermediary characteristic that mediates between raw gas concentration measurements and source identification. This intermediate analysis layer enables differentiation between leaks and other gas sources by examining the spatial scale of concentration variations.
3Area of stationary object
If conventional mobile gas leak detection methods are used, then gas leak detection can be performed over a large region, but lack of an estimated distance to the leak source occurs
Solution Approach 1:
The patent introduces a new dimension of analysis by examining the horizontal spatial scale of concentration variations. Instead of merely measuring concentration magnitude, the system analyzes how concentration changes across space, adding a spatial scale dimension that enables differentiation between leaks and background gas levels.
Solution Approach 2:
The patent replaces direct mechanical distance measurement with an indirect method based on spatial scale analysis of gas concentration patterns. By analyzing the horizontal extent of concentration variations, the system infers distance information without requiring direct ranging capabilities.

AI summary
Improved gas leak detection from moving platforms is provided. Automatic horizontal spatial scale analysis can be performed in order to distinguish a leak from background levels of the measured gas. Source identification can be provided by using isotopic ratios and/or chemical tracers to distinguish gas leaks from other sources of the measured gas. Multi-point measurements combined with spatial analysis of the multi-point measurement results can provide leak source distance estimates. These methods can be practiced individually or in any combination.
