Abstract: A modeling system for universal specification of user interfaces. The system provides a means for defining user interfaces, including highly complex and dynamic user interfaces, in a manner that is independent of any implementation context. The modeling system leads from a user-friendly visual representation of the user interface, through progressively detailed specifications of structural and behavioral aspects of the user interface parts, until a rigorous definition of the user interface in all its contexts of use is achieved. Using the information captured in the model, tools that automatically generate the fully working user interface code can be built.

Abstract: A direct-write laser lithography system comprises a reel-to-reel feed system in a vacuum chamber that presents the clear film-side of a single-sided metal-clad tape to a laser for direct patterning of the metal. The laser beam is swept laterally across the tape by rotating mirrors, and is intense enough to ablate the metal but not so strong as to destroy the tape substrate. In one instance, two specialized lasers are used, one set to ablate large field areas, and the other tuned to scribe fine features and lines. The ablated metal blows off in a downward direction and is collected for recycling.
