MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641052010 A) filed by Chaitanya Bharathi Institute Of Technology, Hyderabad, Telangana, on April 23, for 'portable optical imaging device and method for multi-parameter water quality analysis.'
Inventor(s) include Manda, Pavan Kalyan; Chinthala, Sai Sriharsha; Katarapu, Khashyap; Ammana, Supraja Reddy; Pasika, Sathish; Nallagatla, Jagan Mohan Reddy; and Choudhury, Umakanta.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "A portable water quality analysis device is disclosed comprising a tray (100), illumination unit (101), camera (103), and controller unit (102). A reacted colorimetric test strip is positioned within the tray (100) and imaged under controlled illumination from the illumination unit (101) within an optically isolated environment. The camera (103) captures image data, which is processed by the controller unit (102) to identify reagent pad regions and extract colour features. The extracted features are converted into CIELAB colour space values and evaluated using a prediction model to determine multiple water quality parameters. The controller unit (102) further generates a water quality index and classification. Results are displayed via a display (105). The device ensures consistent positioning, minimizes ambient light interference, and provides accurate, repeatable, and portable multi-parameter water quality analysis."
