MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611024472 A) filed by Chandigarh University, Mohali, Punjab, on March 2, for 'an integrated vision-audio based system for silence enforcement and academic integrity monitoring.'
Inventor(s) include Laxmish Saini; Parveen Badoni; and Mohit.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses an integrated vision-audio-based monitoring system for maintaining silence and ensuring behavioural compliance in shared indoor environments such as libraries, study rooms, classrooms, and examination halls. The system comprises a camera, a microphone, an embedded processing unit, and alerting means housed within a compact enclosure. Visual data are analyzed to detect gradual posture drift and micro-movement patterns of occupants over defined temporal windows, while audio data are processed to identify noise anomalies relative to an adaptive quiet baseline. A multimodal fusion engine correlates synchronized visual and acoustic cues in accordance with configurable operational modes, including library and examination modes. The system generates a real-time, graduated deterrence response through visual and/or audible alerts upon detection of a disturbance or anomalous behaviour exceeding predefined thresholds. The invention operates primarily at the edge, minimizes reliance on cloud infrastructure, and incorporates privacy-preserving measures such as limited data retention and optional redaction."
