Abstract: This invention discloses a method for printed circuit board (PCB) inspection, including providing a multiplicity of PCBs placed on an inspection panel, defining each non-identical PCB in terms of geometry and features which are to be inspected, grouping the PCBs into at least one cluster, the at least one cluster being defined in terms of an amount, location and orientation of the PCBs in the at least one cluster, creating a reference image for the panel defined by a location and orientation of the at least one cluster on the panel and inspecting the panel by comparing sensed information with the reference image.

Abstract: Protective goggles having a rigid, ballistically resistant transparent shield sealingly fittable over the eyes of a wearer via a resilient gasket having airing ports and a head gear for supporting the goggles. A second transparent radiation protective shield is detachably retained exterior to the ballistically resistant shield and in parallel relation thereto with impervious sealing means provided between both shields along their peripheries so as to provide an air-tight space therebetween.
