NON-CONTACT BABY MONITORING USING ARTIFICIAL INTELLIGENCE
Use of non-contact monitoring systems to monitor a subject (e.g., baby, infant, child) in a sleeping or resting environment. The systems utilize artificial intelligence (AI) to identify potential hazards to the subject and alert a caregiver. The systems can be trained to recognize the location of an object as a potential hazard, recognize the location of an object as not a potential hazard, and/or to recognize the type of object as not a potential hazard. The caregiver may acknowledge the potential hazard is indeed a hazard or may clear the potential hazard and the alert, which the system will remember for subsequent like occurrences.
Use of non-contact monitoring systems to monitor a subject (e.g., baby, infant, child) in a sleeping or resting environment. The systems identify the position of the subject and alert a caregiver if the subject is in a potentially hazardous position, such as lying prone (on their front) or if the subject has remained in the same position for a period of time longer than a threshold time. The non-contact monitoring systems can be configured to detect a physical attribute (e.g., respiration rate, tidal volume, pulse, etc.).
