Queen’s Partnerships and Innovation is pleased to report the issuance of U.S. Patent No. 11,910,291 "Sensor and System for Monitoring Dispenser Levels, Traffic Flow, and Staff Location" on February 20, 2024 to Cole MacDonald. The patent relates to an electronic material sensor for a container, such as a dispenser for paper or liquid materials, or a waste receptacle, in a facility such as a restroom. The sensors and system send real-time data to cleaning and maintenance staff when materials in dispensers need to be replenished and receptacles need to be emptied. Managers can use the system to schedule cleaning according to traffic and location of staff.
