| 20090164340 | SYSTEM AND METHOD FOR POPULATING A GIFT REGISTRY USING UPLOADED PRODUCT INFORMATION - According to one embodiment of the invention, a method comprises recovering a product identifier downloaded from portable electronic device, and thereafter, searching a database by the portable electronic device. This search uses a product identifier to uncover any occurrences of the product associated with the product identifier in a database containing multiple products from multiples retailers. Thereafter, a message including a name of one or more merchants selling the product or an item equivalent to the product, and a price of the product or the item equivalent to the product is returned. | 06-25-2009 |

| 20090111046 | Direct laser and ultraviolet lithography of porous silicon photonic crystal devices - We have developed a simple method to locally change the optical properties of porous silicon multilayers and photonic crystal architectures. This technique allows for the direct photolithography of porous silicon multilayers, heterostructures, and photonic crystals. The procedure controls the local oxidation within the porous silicon layers via ultraviolet radiation or via high intensity laser beam (λ=532.8 nm) exposure. Subsequently, immersion of the non-irradiated and irradiated regions of the porous silicon heterostructures within an alcohol solvent (for example, methanol and ethanol) induces either a marked degradation or no degradation, respectively, in the optical properties of the material. This direct, optical lithographic technique may have significant use in the production of silicon-based optical and opto-electronic devices for laser, optical computation, telecommunications, and other applications. Potential devices include patternable porous silicon waveguides, optical filter, optical switches, and photonic band-gap structures. | 04-30-2009 |
