Organic Optical Limiter with a Strong Nonlinear Absorptive Response

Abstract: Molecules with weak ground-state absorption that form strongly absorbing excited states can be used in optical limiters, which can protect sensors or human eyes from optical damage. Phthalocyanine complexes bearing heavy atoms or paramagnetic groups or in solvents containing heavy atoms show optical limiting enhanced by excited triplet-state absorption. A nonhomogeneous distribution of indium tetra(tert-butyl)phthalocyanine chloride along the beam path substantially enhances the excited-state absorption, yielding an optical limiter with a linear transmittance of 0.70 that can attenuate 8-nanosecond, 532-nanometer laser pulses by factors of up to 540.

Portal server that provides a customizable user interface for access to computer networks

Abstract: A portal server presents an HTML page that comprises a plurality of modules that are formatted in a predetermined layout. Each module represents a network resource that can be accessed by a user through the portal. Some of the modules can be user-selectable, whereas others may be mandatory elements of the portal. Similarly, some aspects of the layout may be user-controllable, while others are fixed. The modular nature of the portal enables the various resources to be readily and independently updated by the entities who provide them, without affecting other features of the portal. The portal server includes an administration interface that enables an administrator to select from various layout styles, as well as control access to site information and services. A variety of customizations can be done to the portal without requiring programming skills. As a result, individual businesses and other entities can exercise complete ownership of their portals, from a hosting, branding and design perspective.
