Regarding TrueDrop ® And RealDrop ® Declaration of trademark registration.

Shanghai Solon Information Technology Co., Ltd. for TrueDrop ® And RealDrop ® The legitimate owner of the trademark. Our company has not authorized any other entity to use or indirectly use the above trademark. The above trademark is used for supporting software CAST, including but not for the company's analytical instruments ®、 Product brochures, product manuals, website promotions, etc. shall not use the above trademarks for methods such as "TrueDrop Method" and "RealDrop Method". If there is any infringement, our company will hold the infringer responsible in accordance with the Trademark Law or the Unfair Competition Law.

For the unauthorized use of trademarks by our company, we will use legal means to safeguard our legitimate rights and interests.

At the same time, we remind our users that, TrueDrop ® The technology adopts artificial intelligence image recognition technology and uses Spline interpolation method to sub-pixel contour edges. It comprehensively analyzes different geometric models (such as double circle curves, double ellipse curves, double polynomial curves, etc.) through iterative analysis using artificial intelligence technology to calculate dynamic contact angles. And RealDrop ® The technology adopts artificial intelligence image recognition technology and utilizes spline curves to optimize edges to sub pixels. Based on first principles and classical physical and chemical principles with volume and absorption, the solution calculates dynamic contact angle values and 3D contact angle values in 3D space. There are essential differences between the above technology and the technology routes of other companies. Trademark TrueDrop ® And RealDrop ® They represent different technological routes, namely empirical geometric model driven or first principles driven. Therefore, when purchasing a contact angle measuring instrument or a water droplet angle measuring instrument, please recognize the registered trademark.

Hereby declare.
