MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621042906 A) filed by Mr. Aniket Ashok Jangam; Dr. Sanjay Laxmikant Nalbalwar; Mr. Tejas Umesh Mahagaonkar; Miss. Diksha Sandip Pandharkame; and Dr. Babasaheb Ambedkar Technological University, Raigad, Maharashtra, on April 3, for 'multi- dimensional portable obstacle detection system using multi-sensor feedback for visually disabled persons.'
Inventor(s) include Mr. Aniket Ashok Jangam; Dr. Sanjay Laxmikant Nalbalwar; Mr. Tejas Umesh Mahagaonkar; and Miss. Diksha Sandip Pandharkame.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a portable obstacle detection system configured to assist visually disabled persons in safe and independent navigation through real-time environmental sensing and feedback. The system comprises a plurality of ultrasonic sensing units arranged to detect obstacles in multiple directions, a processing unit configured to determine distance values based on received echo signals, a plurality of vibration units mapped to respective sensing directions, an acoustic alert unit, and a power supply unit. The processing unit is further configured to compare measured distance values with predefined threshold values and to generate direction-specific tactile feedback by selectively actuating corresponding vibration units. The vibration intensity and frequency are dynamically modulated based on proximity of detected obstacles to convey distance information. Upon detection of ground-level hazards such as steps or pits, the system simultaneously activates a downward vibration unit and the acoustic alert unit to provide a dual warning signal."
