MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202641121079 A) filed by Rajalakshmi Engineering College on October 09, 2026, for Intelligent Door Handle With Integrated Fall Detection And Automatic Emergency Response System.
Inventors include Dr. M. Thangamani; Dr. R. Kavitha; S. Umamaheswararao; Dr. A. Rajkumar; and Dr. S. Gunasekar.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: This specification describes a self-contained, battery-powered, retrofit door handle apparatus for detecting human fall events inside a closed room and automatically enabling emergency access. The apparatus integrates a vibration sensing module (100) with a tri-axial MEMS accelerometer (110) and piezoelectric vibration sensor (120), an acoustic sensing module (200) with a dual MEMS microphone array (210), and a processing module (400) executing a multi-sensor fusion fall classification model (450) on a low-power microcontroller (410). A post-fall activity monitoring module (300) with passive infrared (310) and radar micro-motion (320) sensors confirms falls by detecting absence of post-impact activity over a configurable timeout. Upon confirmed detection, an electromagnetic lock release mechanism (510) automatically unlocks the door, and an emergency alert module (600) dispatches tiered notifications via Wi-Fi (610), Bluetooth (620), and GSM/4G cellular (630) to pre-registered contacts. The apparatus requires no building modification, no wearable device, and no cameras.
