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. 11,857,472.

Summary of the Inventive Concept

A novel system integrating wheelchairs with vehicles using blockchain, IoT, AI, and machine learning technologies to provide secure, efficient, and personalized wheelchair-vehicle pairing.

Background and Problem Solved

The original patent addressed the limitations of traditional wheelchairs, but the new inventive concept tackles the challenge of integrating wheelchairs with vehicles, enhancing user experience and accessibility. The original patent's limitations included the lack of secure and efficient wheelchair-vehicle pairing, which is now addressed by the new system.

Detailed Description of the Inventive Concept

The smart wheelchair-vehicle integration system comprises a wheelchair with a seat and body frame, and a vehicle with a side sill forming a door opening. The system integrates blockchain-based authentication, IoT sensors, AI-powered interfaces, and machine learning algorithms to optimize wheelchair-vehicle pairing. The system enables secure and authorized wheelchair-vehicle pairing, detects user approach, and automatically deploys the integration system. It also provides a personalized and optimized user experience based on user behavior and preferences.

Novelty and Inventive Step

The new claims introduce the novel combination of blockchain, IoT, AI, and machine learning technologies to achieve secure, efficient, and personalized wheelchair-vehicle integration, which is not anticipated by the original patent.

Alternative Embodiments and Variations

Alternative embodiments could include using different authentication methods, such as biometric authentication, or integrating the system with other assistive technologies. Variations could include adapting the system for different types of vehicles or wheelchairs.

Potential Commercial Applications and Market

The smart wheelchair-vehicle integration system has significant commercial potential in the healthcare, automotive, and assistive technology industries, enhancing the mobility and independence of people with disabilities.
