Detecting unauthorized visitors

The system uses special 3D cameras to watch a patient's room. It identifies people by their facial features and checks if they are on an approved visitor list. If an unknown person is detected or someone gets too close to the patient, an alert is sent to caregivers through a central system.

Why it matters: Since 2019, AI-powered facial recognition and 3D depth sensing have dramatically improved in accuracy and accessibility. This makes the real-time comparison and identification described in the claims more robust and less resource-intensive.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: Specialized3D sensors, facial recognition software, network system
