Patent ID: 7510324

Claim:
A method of inspecting articles to determine the presence of objects located within said articles, said method comprising: providing a frame structure; using a plurality of heat-generating imaging devices positioned on said frame structure to direct beams onto articles located substantially within said frame structure to thereby inspect said articles; providing output signals from said plurality of heat-generating imaging devices as a result of said inspecting; processing and analyzing said output signals from said plurality of heat-generating imaging devices to identify said objects within said articles; and using a fan to direct cooling fluid in a substantially first direction to a plurality of fluid deflectors spacedly positioned on said frame structure relative to said heat-generating imaging devices; and using said plurality of fluid deflectors to direct said cooling fluid over said plurality of heat-generating imaging devices to cool said heat-generating imaging devices during operation thereof, selected ones of said fluid deflectors deflecting at least some of said cooling fluid from said fan onto selected ones of said heat-generating imaging devices.
