SYSTEMS AND METHOD FOR MAINTAINING A GAP BETWEEN SUCCESSIVE OBJECTS
First Claim
1. A method for maintaining a predetermined gap between successive objects to be scanned by a security scanning machine, said method comprising:
- measuring an initial gap defined between a trailing edge of a first object and a leading edge of a second object; and
based on a comparison between the initial gap and the predetermined gap, controlling a speed of a first conveyor relative to a speed of a second conveyor operatively coupled to the first conveyor such that the predetermined gap between the first object and the second object is maintained.

Abstract
Systems and method are provided for controlling a gap between objects to be scanned by security scanning systems. In one aspect, a method is provided for maintaining a predetermined gap between successive objects to be scanned by a security scanning machine. The method includes measuring an initial gap defined between a trailing edge of a first object and a leading edge of a second object and, based on a comparison between the initial gap and the predetermined gap, controlling a speed of a first conveyor relative to a speed of a second conveyor operatively coupled to the first conveyor such that the predetermined gap between the first object and the second object is maintained.

10. A system for maintaining a predetermined gap between successive objects to be scanned by a security scanning machine, said system comprising:
-
a plurality of sensors configured to sense a position of a trailing edge of the first object and a position of a leading edge of the second object, an initial gap is defined by a distance between the first object trailing edge and the second object leading edge; a plurality of encoders, each encoder of the plurality of encoders configured to generate a pulse signal for each unit of distance traveled by a respective conveyor of a plurality of conveyors; and a processor coupled in signal communication to said plurality of sensors and said plurality of encoders, said processor configured to control a speed of said first conveyor relative to a speed of said second conveyor such that the predetermined gap between the first object trailing edge and the second object leading edge is maintained. - View Dependent Claims (11, 12, 13, 14, 15)

16. A baggage handling system for maintaining a predetermined gap between successive objects to be scanned by a security scanning machine, said baggage handling system comprising:
-
a plurality of conveyors operatively coupled to enable a first object and a second object to travel towards the security scanning machine, said plurality of conveyors comprising a first conveyor and a second conveyor; a sensor configured to; sense a position of a trailing edge of the first object; generate a first signal representative of the first object trailing edge position; sense a position of a leading edge of the second object; and generate a second signal representative of the second object leading edge position; a plurality of encoders, each encoder of said plurality of encoders configured to generate a pulse signal for each unit of distance traveled by a respective conveyor of said plurality of conveyors; and a processor coupled in signal communication to said sensor and said plurality of encoders, said processor configured to; receive the first and second signals from said sensor; receive the pulse signal from each said encoder; and control a speed of said first conveyor relative to a speed of said second conveyor to facilitate maintaining the predetermined gap. - View Dependent Claims (17, 18, 19, 20)
