MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541134380 A) filed by Ifet College Of Engineering, Viluppuram, Tamil Nadu, on Dec. 31, 2025, for 'autonomous multi-sensor wearable safety ring with distress detection and location-based emergency alerting.'
Inventor(s) include Mrs. D. Thamizhisai; T. Sachin; Ms. Anandhajothinalini. R; and Mrs. K. Elavarasi.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "An autonomous wearable safety ring system is disclosed, comprising a wearable ring housing [102], a heart-rate sensing unit [104], a skin-conductance sensing unit [106], a three-axis motion sensing unit [108], a microcontroller unit [110], a cellular communication module [112], a location coordinate module [114], a rechargeable battery [116], and optimized low-power circuitry [118]. The microcontroller unit [110] continuously acquires physiological and motion signals from the sensing units [104, 106, 108], preprocesses the signals using filtering, and generates sensor-fusion analysis values. A distress condition is determined based on threshold logic combined with a trained classifier to identify abnormal physiological and/or motion patterns without requiring manual activation by a user. Upon determining distress, the cellular communication module [112] transmits an emergency alert message including real-time location coordinates from the location coordinate module [114] to one or more pre-registered recipients, and event data is uploaded to a cloud platform for remote tracking and data storage."
