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. 11,857,723.

Summary of the Inventive Concept

The inventive concept leverages the core technology of the original patent to deliver air in various non-medical settings, such as greenhouses, fish tanks, data centers, tunnels, and warehouses, providing a cost-effective and efficient solution for air circulation and ventilation.

Background and Problem Solved

The original patent focused on devices and methods for delivering air to a patient, primarily in the context of cardiopulmonary resuscitation (CPR). However, the limitations of this patent lie in its narrow application scope. The new inventive concept addresses this limitation by applying the core technology to a broader range of industries and use cases, solving the problem of inefficient air circulation and ventilation in these settings.

Detailed Description of the Inventive Concept

The inventive concept comprises a first portion with a first airflow inlet and a sensor configured to sense airflow, defining a first airflow path. A second portion includes a second airflow inlet, an impeller, and an outlet for communicating airflow to the target environment (e.g., greenhouse, fish tank, data center, tunnel, or warehouse). The sensor sensing airflow in the first portion drives the corresponding movement of the impeller, which impels air from the surrounding atmosphere through the second portion and into the target environment. This design enables efficient air circulation and ventilation, improving the overall environment and reducing the risk of stagnation.

Novelty and Inventive Step

The new claims introduce a novel application of the core technology, expanding its scope beyond medical devices to various non-medical industries. The inventive step lies in the adaptation of the sensor-driven impeller design to address the specific needs of these new environments, providing a unique solution for air circulation and ventilation.

Alternative Embodiments and Variations

Alternative embodiments may include variations in sensor types, impeller designs, and airflow path configurations to accommodate specific requirements of different industries. For example, a modified sensor could be used to detect air quality or temperature, triggering the impeller to adjust airflow accordingly. Additionally, the system could be integrated with existing ventilation infrastructure or designed as a standalone unit.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including agriculture (greenhouses), aquaculture (fish tanks), data center management, tunnel construction, and warehouse management. The market for air circulation and ventilation solutions in these sectors is substantial, with a growing demand for efficient and cost-effective solutions.
