Abstract: An enhanced steam cycle utilizing a dual pressure recovery boiler with reheat. A dual pressure designed recovery boiler furnace is provided with a lower furnace and an upper furnace. The lower furnace is operated at a lower temperature to prevent or reduce corrosion of the lower furnace wall tubes. The lower furnace can be either a low pressure natural circulation steam generating (drum) system or economizer. The upper furnace operates as a high pressure natural circulation steam generating (drum) system, or as a once-through supercritical steam generating system at higher temperatures and pressures permitting implementation of higher efficiency reheat steam cycles.

Abstract: A push gateway includes a number of socket servers, a queue server, and arbiter serving, a mapping server and a number of worker servers. Each of the socket servers and the arbiter server includes a network interface. The queue server is coupled to the socket servers for bidirectional communication with the socket servers. The mapping server is coupled to the arbiter server and to the socket servers for bidirectional communication with the arbiter server and each of the socket servers. The worker servers are coupled to the queue serer and the mapping server. The arbiter server is configured to facilitate communications over a network with the worker servers by at least partially balancing loads on the number of socket servers based, at least in part, upon the mapping server.

Abstract: Systems and methods for providing authentication using an arrangement of dynamic graphical images, which may display a popup element while a pointing device indicator is over a graphical image. The graphical images can be arranged as a grid or matrix for presentation on a device display for authentication of a user. The kinds of graphical images can be derived from a designated authentication category and non-authenticating categories. A series of password elements corresponding to the graphical images can be displayed with the graphical images. The user may enter the series of one or more password elements corresponding to graphical images from the authentication category which combine to form a password entry. An authentication server can compare the password entry to an authentication password corresponding to the particular arrangement of dynamic graphical images.

Abstract: A method and system for protection of and secure access to a computer system or computer network. The method includes the steps of receiving a first login account identifier, such as a user name from a user in communication with the computer system or network. A determination is made if the user is recognized and enrolled from the first login account from the first login account identifier. If the user is recognized, a grid of randomly generated visual images is displayed including one visual image from an image category which has been preselected by the user upon enrollment. An image category identifier is randomly assigned to each visual image in the grid. An image category identifier, second login account identifier, such as a password, is entered and received. If the login account identifier and the image category is validated, access is permitted to the computer system or network.

The selection of graphical images, their arrangement and their corresponding password elements, may dynamically change in between authentication processes.

Abstract: The invention provides methods and systems for management of image-based password accounts. A password management account may be accessed by a user undergoing image-based authentication. The invention may allow a user to manage parameters relating to image-based authentication. The invention may also allow a user to manage authentication at one or more web site.

Abstract: An enhanced steam cycle utilizing a dual pressure recovery boiler with reheat allows a large increase in electrical generation with various turbine cycles while overcoming traditional lower furnace material limitations. A dual pressure designed recovery boiler furnace is provided with a lower furnace and an upper furnace. The lower furnace is operated at a lower temperature to prevent or reduce corrosion of the lower furnace wall tubes caused by the reducing environment. The lower furnace can be either a low pressure natural circulation steam generating (drum) system or economizer. Unlike the lower furnace, the upper furnace is not exposed to a reducing environment and is therefore not as susceptible to severe corrosion rates. The upper furnace is operated at higher temperatures and pressures which permit implementation of higher efficiency reheat steam cycles.

Abstract: The present invention is directed to a graphical image identity authentication system. In particular, the invention is directed to methods and systems for graphical security authentication and advertising. A security authentication system may receive advertisements from an advertising service company, process the advertisements to integrate them into the graphical image identity authentication system, and transmit the processed advertisement information back to the advertisement service company. The security authentication system may also monitor user interaction with the advertisements and transmit the logged information to the advertising service company.

Abstract: A method and system for protection of and secure access to a computer system or computer network from a portable device. The method includes the steps of receiving a first login account identifier, such as a user name from a user in communication with the computer system or network. A determination is made if the user is recognized and enrolled from the first login account identifier. If the user is recognized, a series of randomly generated visual images is displayed including one visual image from an image category which has been pre-selected by the user upon enrollment. An image category identifier is randomly assigned to each visual image in the series. An image category identifier is entered and received. If the login account identifier and the image category are validated, access is permitted to the computer system or network from the portable device.
