MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541132124 A) filed by Sri Manakula Vinayagar Engineering College, Pondicherry, India, on Dec. 26, 2025, for 'advance ultrasonic sensor based non contact proximity detection and automatic switching system for energy efficient and hands free device control.'
Inventor(s) include Dr. P Raja; Dr. T. Deepa; Dr. N. Saranya; S. Jayanthi; K. Sarangi; R. Yuvashri; and K. Vishalini.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "This invention relates to an advanced ultrasonic sensor-based non-contact proximity detection and automatic switching system for energy-efficient and hands-free device control. It typically includes an ultrasonic sensor (1), a relay module (2), a microcontroller (3), a power supply (4), a voltage regulator (5), a logic level shifter (6), a tft display module (7), a protective enclosure (8), a load device (9), and a connecting wires and breadboard (10). This system offers a superior alternative to traditional switches by providing hygiene-focused, real-time contactless control that is unaffected by ambient light or noise, reduces mechanical wear, and enables energy-efficient, autonomous operation across homes, hospitals, and industrial environments. The applications of this system include sterile control of medical equipment in hospitals to reduce cross-contamination, hands-free machine operation in industrial environments where hands may be gloved or soiled, and the hygienic automation of lights, fans, and public kiosks like ATMs or elevators to prevent surface-borne infection and improve energy efficiency."
