What are the core patents of Nakagawa Xinmai? I want to speed up my understanding.

At present, the company has a number of patents for invention of core technologies in photoacoustic field, including photoacoustic noninvasive blood glucose detection system, endoscopic medical imaging diagnosis system based on photoacoustic technology, photoacoustic breast medical imaging system, photoacoustic dual-mode imaging system and so on. And a number of products independently developed and produced are being put into production one after another?
