MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202431004109 A) filed by Institute Of Engineering & Management, Kolkata, West Bengal, on Jan. 20, 2024, for 'cellsignal proximitor.'
Inventor(s) include Sujay Kumar Dolai.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "The Mobile Phone Detector Circuit is a novel electrical circuit that was designed to recognise the presence of active mobile phones within a limited space that are transmitting radio frequency (RF) signals. Along with capacitors, resistors, a BC548 NPN transistor, and a 5mm Red LED, this circuit incorporates an LM358 Dual Op-Amp IC as the primary detector of RF signals. Other components include a 5mm Red LED. The RF signals that are picked up by a 15 cm Single Strand Wire Antenna are interpreted by the LM358 Op-Amp, which is functioning as a frequency detector. Signal transfer is facilitated by capacitors, and the BC548 transistor controls the amount of LED illumination in response to the detection of RF signals. Adjusting the sensitivity of a 2.2M Potentiometer such that it fits a variety of detection ranges is possible. The LED functions as a visual indicator whenever an active mobile phone within a range of 1.5 metres generates radio frequency (RF) signals. The adaptability of this circuit makes it useful for applications in security systems and other domains where mobile phone activity monitoring is required. Because of its versatile construction and accurate detecting capabilities, it is a useful instrument in a variety of different contexts."
