Visual System Characterization for Specialized Environments
Legal Citation
Summary of the Inventive Concept
This inventive concept adapts the visual system characterization method for specific, narrow markets or unique operational environments, such as high-security needs, disaster relief, extreme weather conditions, or high-stress operational environments.
Background and Problem Solved
The original patent disclosed a method and system for characterizing the visual system of a subject using measures of sensitivity to contrast. However, this method may not be suitable for specific environments where visual conditions are degraded or noise levels are high. The new inventive concept addresses these limitations by adapting the method to accommodate these unique environments.
Detailed Description of the Inventive Concept
The new inventive concept comprises a visual test adapted to the specific environment, which measures the sensitivity to contrast of the visual system in the presence of external noise or degraded visual conditions. The system includes a data processing module that quantifies the impact of internal noise sources on the sensitivity to contrast, providing a comprehensive characterization of the visual system. For high-security environments, the visual test is designed to operate in low-light conditions and high-noise levels. In disaster relief scenarios, the system is portable and compact, allowing for on-site testing. For extreme weather conditions, the visual test compensates for visual degradation caused by weather-related factors. In high-stress operational environments, the system operates in real-time, providing immediate feedback.
Novelty and Inventive Step
The new claims introduce novel adaptations of the original method to specific, narrow markets or unique operational environments. The inventive step lies in the design of the visual test and data processing module to accommodate these environments, which is not obvious from the original patent.
Alternative Embodiments and Variations
Alternative embodiments may include adapting the visual test to specific industries, such as aviation or maritime, or developing specialized software for data analysis. Variations may include using different types of visual tests or data processing algorithms to quantify the impact of internal noise sources.
Potential Commercial Applications and Market
The inventive concept has potential commercial applications in various industries, including defense, healthcare, and disaster relief. The target market includes organizations operating in high-security environments, disaster relief teams, and individuals working in extreme weather conditions or high-stress operational environments.
