RESIDENCE FALL AND INACTIVITY MONITORING SYSTEM

摘要

A surveillance system for residential buildings that monitors the status of occupants for their location, position, and movement. The system employs a sensor that is mounted near the ceiling or on the floor in each room of the residence. Each sensor continuously scans the X, Y and Z axes for the location and position of objects each room. The sensors are coupled to a digital image processor that uses software to evaluate the stream of location and position data to determine whether occupants are moving, and whether their activity indicates an or normal or emergency condition. The surveillance system can be adapted for any building or room configuration because upon setup it generates and stores a database of map information about the building it is installed within and that map data is thereafter used to evaluate the stream of location and position data. When abnormal location, position or movement of a monitored object, typically a senior citizen, is detected by the system an alarm state is automatically triggered and an emergency notification signal is transmitted to emergency response personnel.

主权项

1. A method of detecting changes in status of an individual in a residence comprising,
a. at least three wireless detection modules located in the residence and configured to continuously monitor the individual's location and movements in the residence, each the wireless detection module includes a 3D radar scanner; b. a digital image processing unit coupled to the three wireless detection modules, the digital image processing unit includes working memory; c. a fall and inactivity detection software program loaded into the working memory of the digital image processing unit, the software program configured to make multi-lateration measurements of the three return signals from the wireless detection modules to identify the exact location of an object in the residence, the software program creates a map database of the residence identifying the rooms in the and any the physically structures or barriers in the residence, the software program able to detected falls or inactivity of the individual inside the residence and generate an alarm signal, the software program being configured to create a history database of the individual's movements or inactivity prior to the alarm signal; and d. a response subsystem coupled to the digital image processor and configured to notify a caregiver or emergency personnel when an alarm state from the software program is received.
