Open confined area object detection
First Claim
1. Apparatus for providing alarm indications of objects in spaces subject to vehicle movements, the apparatus comprising:
- a scanner unit configured to provide indications of directions of movement of objects and distances of objects within a scan area and provide the indications as a signal output;
a driver unit configured to cause the scanner unit to scan the scan area;
a computer configured to compare the signal output from the scanner unit and resolve the signal output to a pattern of the indications of directions of movement of objects and distances of objects over multiple instances of the indications over time, to determine movement corresponding to the movement of the objects based on the pattern of the indications of directions of movement and distances;
the computer further configured to compare the indications of objects and of movements of the objects to render an indication of objects partially blocked by other ones of the objects from line-of-sight of the scanner unit; and
an indicator output, whereby predetermined relative movements of the objects as resolved by the computer render predetermined indicator or alarm signals.

Abstract
Alarm indications of objects (431, 631) in spaces (113) subject to vehicle movements are provided using a scanner unit configured to provide indications of directions and distances of objects within a scan area. A computer compares the signal output from a scanner unit (121) and resolves the signal output to a pattern of the indications of directions and distances, and further resolve multiple instances of the indications over time to resolve the pattern of indications and distances to movement corresponding to the movement of the objects (431, 631). The indications are compared to render an indication of objects (431) partially blocked by other ones (631) of the objects from line-of-sight of the scanner unit (121). Predetermined relative movements of the objects (431, 631) as resolved by the computer render predetermined indicator or alarm signals (341, 342, 345).

8. Method for providing alarm indications of objects in spaces subject to vehicle movements, the method comprising:
-
configuring a scanner unit to provide indications of directions of movement of objects and distances of objects within a scan area and provide the indications as a signal output and driving the scanner unit to scan the scan area; using a computer to compare the signal output from the scanner unit and to resolve the signal output to a pattern of the indications of directions of movement of objects and distances of objects over multiple instances of the indications over time, to determine movement corresponding to the movement of the objects based on the pattern of the indications of directions of movement and distances; using the computer to compare the indications of objects and of movements of the objects to render an indication of objects partially blocked by other ones of the objects from line-of-sight of the scanner unit; and using predetermined relative movements of the objects as resolved by the computer to render predetermined indicator or alarm signals. - View Dependent Claims (9, 10, 11, 12, 13, 14)
