This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,339.

Summary of the Inventive Concept

A system for monitoring and improving indoor air quality in commercial aircraft, utilizing a headgear-type device to detect biometric information and air quality information around passengers, and transmit the information to a central server for analysis and personalized air quality recommendations.

Background and Problem Solved

The original patent relates to a headgear-type device for hazardous air quality warning and air quality improvement in industrial settings. However, the growing concern about air quality in commercial aircraft cabins has highlighted the need for a dedicated solution. The present inventive concept addresses this limitation by adapting the core technology to the aviation industry, providing a novel system for monitoring and improving indoor air quality in commercial aircraft.

Detailed Description of the Inventive Concept

The Airborne Air Quality Monitoring and Improvement System consists of a headgear-type device worn by passengers, which detects biometric information such as heart rate and respiratory rate, as well as air quality information around the passenger. The device transmits this information to a central server, which analyzes the data and provides personalized air quality recommendations to the passenger. The system can also adjust air quality parameters in the aircraft cabin based on the collective data from multiple passengers. The headgear-type device can be integrated with the aircraft's ventilation system to provide real-time air quality improvement.

Novelty and Inventive Step

The new claims introduce the concept of applying the headgear-type device to the aviation industry, specifically for monitoring and improving indoor air quality in commercial aircraft. This adaptation is non-obvious and novel compared to the original patent, which focused on industrial settings. The inventive step lies in the integration of the headgear-type device with the aircraft's ventilation system and the provision of personalized air quality recommendations to passengers.

Alternative Embodiments and Variations

Alternative embodiments of the Airborne Air Quality Monitoring and Improvement System could include wearable devices other than headgear, such as wristbands or smart clothing. The system could also be integrated with other aircraft systems, such as the entertainment or navigation systems, to provide a more comprehensive passenger experience.

Potential Commercial Applications and Market

The Airborne Air Quality Monitoring and Improvement System has significant commercial potential in the aviation industry, where air quality is a growing concern. The system can be marketed to airlines as a value-added service to enhance passenger comfort and safety. Additionally, the system can be adapted for use in other enclosed environments, such as trains or buses, providing a broader market opportunity.
