Abstract: A lock assembly for an excavator wear assembly, the lock assembly a locking pin having at least one dowel extending outwardly therefrom. The lock assembly also includes a retaining member having a seat and a cavity and a biasing member located within the cavity of the retaining member. The biasing member is adapted to exert a biasing force on the dowel to releasably retain the dowel within the seat of the retaining member.

Abstract: A wear assembly having an adaptor with a spigot portion is disclosed. The spigot portion has a transverse dimension. The wear assembly also has a wear member releasably mountable on the adaptor. The wear member has a body with a socket cavity and the socket cavity is adapted to receive the spigot portion of the adaptor. The wear member also has a pair of mounting ears extending from the body. Each of the mounting ears has a transverse dimension. The transverse dimension of each mounting ear is in the range 0.25 to 0.4 of the transverse dimension of the spigot portion.

Abstract: Automatic optical inspection (AOI) systems are described comprising optical modules that include an illumination component and a lens array configured to direct illumination of the illumination component at a portion of a substrate. The lens array includes a Fresnel lens. The optical module includes a camera that receives reflected light resulting from an interaction of the illumination and the substrate. The camera includes a time delay integration (TDI) sensor. A telecentric imaging lens directs reflected light from the substrate to the camera. The illumination component comprises a controller coupled to multiple LED light sources, each emitting light at a different wavelength. The controller independently controls each LED light source. The illumination component includes a bright field and/or a dark field light source. The illumination component can include a front side and/or a back side light source. An optical fiber is coupled to the camera and an image processor.

Abstract: A significant improvement in the alignment of a particle-beam-generated pattern relative to a pre-existing pattern present on a substrate has been accomplished using optical measurement to register the particle beam to the pre-existing pattern. Use of a position fiducial which can be accurately measured by both an optical microscope and a particle beam axis is used to align a pre-existing pattern with a particle-beam-generated pattern during writing of the particle-beam-generated pattern. Registration of the pre-existing pattern to the fiducial and registration of the particle beam axis to the fiducial periodically during production of the particle-beam-generated pattern continually provides an improvement in the overall alignment of the pattern being created to the pre-existing pattern on the substrate. The improved method of alignment can be used to correct for drift, or thermal expansion, or gravitational sag, by way of example.
