Method for Determining Whether an Individual Enters a Prescribed Virtual Zone Using Skeletal Tracking and 3D Blob Detection
First Claim
1. A system for detecting when a monitored individual or any part of the monitored individual has crossed over a designated electronic perimeter, the system comprising a computerized monitoring system configured to electronically receive data from one or more 3D Camera, Motion and Sound sensors located in a room with an individual to be monitored, track the monitored individual using skeletal tracking if a skeleton is detected, track the monitored individual using virtual blob detection if a skeleton is not detected, and electronically determine whether the monitored individual or a part of the monitored individual has crossed a designated electronic perimeter by either electronic skeletal tracking of the monitored individual or virtual blob detection.

Abstract
A method and system that allows healthcare providers, hospitals, skilled nursing facilities and other persons to monitor disabled, elderly or other high-risk individuals to prevent or reduce falls and/or mitigate the impact of a fall by delivering automated notification of “at risk” behavior and falls by such an individual being monitored where assistance is required. Two systems are used to identify patients, a skeletal tracking system, which identifies patients by biometric indicators, and a virtual blob detection system. In the virtual blob system, the monitored individual is virtually represented as a blob object of at least a specific size by a computerized monitoring system and such system detects and alerts when the blob object enters or crosses into a virtually defined or designated blob detection zone and remains in the zone for at least a predetermined period of time. These systems may be used concurrently, or one system may be used primarily, with the other system acting as a failsafe.

- 1. A system for detecting when a monitored individual or any part of the monitored individual has crossed over a designated electronic perimeter, the system comprising a computerized monitoring system configured to electronically receive data from one or more 3D Camera, Motion and Sound sensors located in a room with an individual to be monitored, track the monitored individual using skeletal tracking if a skeleton is detected, track the monitored individual using virtual blob detection if a skeleton is not detected, and electronically determine whether the monitored individual or a part of the monitored individual has crossed a designated electronic perimeter by either electronic skeletal tracking of the monitored individual or virtual blob detection.
- 14. A system for electronic monitoring of when an individual or any part of the individual crosses over a designated electronic perimeter, the system comprising a computerized monitoring system configured to electronically receive data from one or more 3D Camera, Motion and Sound sensors located in a room, and electronically monitor the room for a crossing of a designated electronic perimeter by the individual based on the data electronically received from the one or more 3D Camera, Motion and Sound sensors, simultaneously using skeletal tracking monitoring based on skeletal points for the individual and virtual blob detection monitoring.

20. A system for detecting when a monitored individual or any part of the monitored individual has crossed over a designated electronic perimeter, the system comprising:
-
one or more 3D Camera, Motion and Sound sensors in a room with the monitored individual; a computerized monitoring system configured to electronically receive data from the one or more 3D Camera, Motion and Sound sensors, track the monitored individual using skeletal tracking if a skeleton is detected, track the monitored individual using virtual blob detection if a skeleton is not detected, and electronically determine whether the monitored individual or a part of the monitored individual has crossed a designated electronic perimeter by either electronic skeletal tracking of the monitored individual or virtual blob detection; and a computerized communication system configured to receive an alert from the electronic monitoring system if the monitored individual or a part of the monitored individual has crossed a designated electronic perimeter and send an audible message to the individual or notify a designated person associated with the individual.
