Method for determining whether an individual enters a prescribed virtual zone using 3D blob detection
First Claim
1. A method for detecting when a monitored individual or any part of the monitored individual has crossed into a designated electronic perimeter, said method comprising the steps of:
- (a) electronically calibrating virtual blob detection zones defining a designated electronic perimeter within an area of the room using a virtual blob detection system;
(b) electronically receiving data by a computerized monitoring system from one or more 3D Camera, Motion and Sound sensors located in the room, the data comprising an IR depth map; and
(c) electronically alerting a computerized communication system when the computerized system detects that a blob object exceeding a preconfigured size that virtually represents an individual located in the room or any part of the individual has crossed into the designated electronic perimeter.

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. 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.

6. A method for detecting when a monitored individual or any part of the monitored individual has crossed into a designated electronic perimeter, said method comprising the steps of:
-
(a) providing one or more 3D Camera, Motion and sound sensors within a room occupied by an individual to be monitored for continuously capturing video from the room; (b) electronically calibrating virtual blob detection zones defining a designated electronic perimeter within an area of the room using a virtual blob detection system; (c) electronically forwarding data representing video and 3D depth data by the one or more sensors to the virtual blob detection system associated solely with the individual, the 3D depth data comprising an IR depth map; and (d) electronically alerting a computerized communication system when the virtual blob detection system detects from the received data that a blob object exceeding a preconfigured size that virtually represents the individual or a part of the individual has entered or crossed into the designated electronic perimeter and remains in the designated electronic perimeter for a sufficient duration. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method for detecting when a monitored individual or any part of the monitored individual has crossed into a virtual blob detection zone, said method comprising the steps of:
-
electronically capturing, using one or more 3D Camera, Motion and Sound Sensors, data of an area of a particular room where an individual is being monitored, the data comprising an IR depth map, the area comprising an electronically calibrated virtual blob detection zone; electronically receiving, by a virtual blob detection system, the data captured from the one or more 3D Camera, Motion and Sound sensors; and electronically alerting a computerized communication system when the virtual blob detection system detects that a blob object exceeding a preconfigured size that virtually represents the individual, or any part of the individual, has crossed into the virtual blob detection zone. - View Dependent Claims (22, 23, 24, 25)
