Abstract: This invention in one aspect relates to an iron-based foam usable for an electrochemical device, comprising a composition comprising iron and a refractory element processed to form the iron-based foam having a hierarchical porous structure with self-assembled channels for gas flow reactions and internal space to accommodate volumetric changes on oxidation.

Abstract: The present invention provides a system for determining when to present information to a user based on web page content. The system includes a retriever engine, a display engine, and a parser engine. The retriever engine transmits a domain to a server. In response, the server transmits information to be displayed and in-context rules, which are received by the retriever engine. The parser engine parses the HTML source code of a web page and decides whether to display the information based on the in-context rules. If it is determined that the information should be displayed, the display engine displays the information.

Abstract: In one embodiment, a computer program blocks windows categorized as bad windows, while allowing windows categorized as good windows to be displayed. The computer program may categorize a window by consulting one or more lists. In one embodiment, a list may be updated from time to time to optimize the computer program and prevent program-obsolescence. Techniques for defeating a window-blocking mechanism are also disclosed. In one embodiment, a computer program detects if a window is of a type that offers a product to a user. If so, the computer program provides a separate window containing information regarding the product. In one embodiment, a computer program detects if a user has a need for the computer program. If so, the user is informed of the efficacy of the computer program, which is then offered to the user.

Abstract: In one embodiment, a web page stored in a first server computer includes a reference to a wrapping code stored in a second server computer. The wrapping code may be pulled into a client computer when the page is downloaded to the client computer. Upon execution in the client computer, the wrapping code may add a functionality to the web page. The functionality added by the wrapping code may be activated along with a pre-existing functionality of the web page in response to a user interaction with the web page.

Abstract: A method and apparatus allowing for entry of form data in a browser. In the described embodiment, a browser automation program executes on the user's computer and communicates with a browser program in order to determine when forms are encountered.
