  • Patent number: 11952273
    Abstract: We disclose herein a viable, cost efficient method for the instantaneous production of hydrogen gas. Hydrogen gas production is increased by utilizing solar and lunar energy. The hydrogen gas is generated spontaneously by the reaction of sodium hydroxide and aluminum as corrosion occurs, forming a layer of aluminum oxide upon the aluminum. This aluminum oxide layer prevents further reaction of sodium hydroxide and aluminum, and thus no more hydrogen gas is produced. Production of aluminum oxide can be bypassed by adding acetic acid or sodium acetate to the reaction. In this reaction the products are aluminum hydroxide and hydrogen gas. Thus, we disclose herein a method that prevents of the formation of aluminum oxide by the use of sodium acetate or acetic acid, the use of iron as a catalyst, and the enhancement of the reaction using natural light.

  • Patent number: 8585812
    Abstract: A novel method for the removal and prevention of rust from corroded iron surfaces is disclosed. This is done by inducing reducing conditions at the interphase between the rusted surface and the attached aluminum surface. An iron coating provided by the reducing conditions surrounds the clean iron and creates a barrier against future rust. Our technology is an oxygen displacement technology which essentially removes rust from iron and iron based tools and structures. It is cost effective, non-invasive, environmentally friendly and can be mass produced.

  • Publication number: 20070022196
    Abstract: A system and method for using multiple factors to verify and thereby authenticate the identity of a user attempting to gain access to a personal account at an on-line service provider. The disclosed system and method may be used by multiple on-line service providers thereby enabling the user to be in possession of a single set of identification factors to gain access to one of multiple accounts. Once the user provides the proper identification factors and the identification factors are verified by matching them against factors stored in a computer, the identity of the user is deemed to be authentic and the user is passed onto the on-line service provider for access to the user's personal account.

  • Publication number: 20060020886
    Abstract: The present invention generally relates to systems and methods for the customization of structured data entry screen templates. The systems and methods include the hierarchical organization of data capture fields, the defining of macro-embedded sentences at each hierarchical level in addition to a set of rules for generating and aggregating sentences. Lastly, the raw captured data and macro-embedded sentences are stored and then merged together with style sheets to generate semantically rich, natural-language documents.
