Abstract: Users exploiting near-to-eye (NR2I) displays for augmented reality and/or correction of low vision are typically wearing these NR2I displays for specific tasks or for extended periods of time, potentially all their time awake. Conflicting tradeoffs between user comfort and minimal fatigue and strain during use, ease of attachment, minimizing intrusiveness and aesthetics should be concurrently balanced with providing an optical vision system that provides the user with a wide field of view, high image resolution, and a large exit pupil for eye placement with sufficient eye clearance. Accordingly, embodiments of the invention provide NR2I displays meeting these conflicts whilst also addressing the inherent variations between user in respect of their head dimensions, head and eye geometry, as well as adapting the displayed content to reflect the user's task at-hand, visual defects or degradations, visual focus and intent upon various regions-of-interest within their field of view.

Abstract: Systems and methods of laying out integrated circuits are disclosed. During the layout stage of an integrated circuit device, a fixed, physical geometry is created of the parameterized cells (PCells) included in the integrated circuit schematic. The systems include a proxy engine configured to save to cache the geometries created during the layout stage such that the geometries need not be recomputed when the design is opened after a save to disk operation, during which geometries may otherwise be destroyed. The proxy engine may further be configured to delegate requests for the creation of geometries to other components of the integrated circuit design system. In addition, the proxy engine may be configured to perform customized evaluations of PCells, other than or in addition to caching and delegation.
