MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202441028151 A) filed by Mr. Gauravjwal Kundu, Bengaluru, Karnataka, on April 5, 2024, for 'a color-patch device for automatic particle detection in parenteral bottles.'
Inventor(s) include Mr. Gauravjwal Kundu.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "A color-patch device for automatic particle detection in parenteral bottles [0050] The present invention discloses a device (100) for automated detection of particles in parenteral bottles (105), combining an alternating black (102) and white (103) stripes with a gray gradient (104) on an acrylic diffuser (101), backlit by Light Emitting Diodes (LEDs). The device (100) identifies the particles by contrast-black particles are visible against white stripes (103) and vice versa. The gray gradient (104) minimizes false positives caused by minor vibrations, interpreted as particle movement at the stripes' boundaries. The Tyndall effect, resulting from light scattering by particles, facilitates the detection of white, transparent and semi-transparent particles. The device (100) streamlines the visual inspection process, merging the capabilities for detecting both black and white particles within bottles of various sizes, into a single station, thereby simplifying the setup and reducing the costs associated with conventional inspection devices."
