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. 11,857,376.

Summary of the Inventive Concept

This inventive concept discloses a novel Patient Interface Module (PIM) that integrates high-efficiency wireless charging, reduced latency wireless communication, and adaptive power management to enhance the performance and safety of intraluminal imaging systems.

Background and Problem Solved

The original patent described a PIM powered by a wireless power system, but it had limitations in terms of power transmission efficiency, latency, and safety. The new inventive concept addresses these limitations by introducing advanced wireless charging, efficient power management, and foreign object detection to ensure reliable and efficient operation.

Detailed Description of the Inventive Concept

The enhanced PIM comprises a high-efficiency wireless charging system that minimizes energy loss, a power management system that dynamically allocates power between the wireless communication module and the imaging signal processing module, and an adaptive impedance matching system that ensures efficient wireless power transfer. The PIM also features a foreign object detection system integrated into the charging base, which interrupts power transmission upon detection of a foreign object. Furthermore, the PIM is designed to communicate imaging signals wirelessly to a processing system with reduced latency.

Novelty and Inventive Step

The new inventive concept's novelty lies in the combination of advanced wireless charging, efficient power management, and foreign object detection, which provides a significant improvement over the original patent. The inventive step is the integration of these features to create a more efficient, safer, and reliable PIM.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different wireless charging technologies, such as resonant inductive coupling or radio frequency (RF) power transmission. Variations could also include the integration of additional safety features, such as thermal monitoring or electrical isolation.

Potential Commercial Applications and Market

The enhanced PIM has significant commercial potential in the medical imaging industry, particularly in intraluminal imaging applications such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT). The market for medical imaging devices is growing, and the inventive concept's improved performance, safety, and efficiency make it an attractive solution for medical device manufacturers and healthcare providers.
