MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202621106722 A) filed by Audirivision Technologies Private Limited on September 04, 2026, for Blur-Tolerant Optical Information Marker Having Range-Graded Payload Tiers And Related Systems And Methods.
Inventor includes Aadhar Bhalinge.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: An optical information marker (100) has a carrier (108) presenting a peripheral locating region (102, 104) and an interior region (106) carrying a continuous-tone field (110) whose payload lies in coefficient signs, not cells. The field is a base level with a superposed modulation, the inverse two-dimensional transform of coefficients allocated among payload tiers (202, 204, 206) in ordered intervals of radial spatial frequency. Each tier has a reference subset (210) bearing predetermined signs, from which a reading device measures that tier's gain and noise, and a data subset (212) whose signs carry data words with check bits (410); for every tier above the lowest, the check bits span a concatenation with a lower tier's payload. Within a colour component, lower tiers survive farther, so the device recovers the lowest tier at long range and higher tiers on approach, each attempted independently and reported only when verified.
