Methods and systems for defining and distributing information alerts include presenting a user with a series of templates that allows the user to define security events, information alerts to be triggered by the events, and intended recipients for the alerts. Intended recipients for the alerts are presented with templates that allow the individuals to input contact and schedule information for receiving the information alerts. A knowledge switch uses the event definitions and the contact and schedule information to detect events and distribute the information alerts to the intended recipients when an event occurs. The information alerts include directives that instruct intended recipients regarding action to be taken in response to a security event.

A method and system for creating, using, and updating individual user voice portals in a multi-user environment is disclosed. Each user selects data sources, keywords and time intervals for searching the data sources, and grammar for accessing search results. Based on this information, an individual voice portal is created for the user. The requested information is extracted from the specified data sources and cached or stored in a database to increase extraction speed. The user accesses the individual voice portal using a unique identifier assigned to the user and the selected grammar. Because each user has a unique voice portal, the search space for software that interprets the grammar is decreased. As a result, the likelihood of misinterpretation and the time for extracting the requested information are decreased.

Image data is converted to nonplanar image data for display on a nonplanar display, using a planar image graphics computer system, such as an OpenGL&reg; system, which converts image data to planar image data for display on a planar display. A transformation matrix is obtained from the planar image graphics computer system. A plurality of vertices of the image data are multiplied by the obtained transformation matrix, to produce transformed image data. The transformed image data is nonplanarly distortion corrected to produce nonplanar image data. A passthrough transformation matrix, such as an identity matrix, is provided to the planar image graphics computer system. The nonplanar image data is then input to the planar image graphics computer system for further processing. The nonplanar image data which is processed by the planar image graphics computer system is then displayed on a nonplanar display. Accordingly, the image data is distortion corrected and manipulated as necessary, so that the distortion corrected image data can be applied to a standard planar image graphics computer system for image processing.

A dual polarization optical projection system and method combines images from first and second image sources. The first image source includes a first array of image pixels wherein the first image source generates a first pixel image having a first polarization. The second image source includes a second array of image pixels wherein the second image source generates a second pixel image having a second polarization orthogonal to the first polarization. The first pixel image having the first polarization is combined with the second pixel image having the second polarization to form a combined pixel image. Each pixel of the combined pixel image corresponds to a combination of a first pixel from the first array of image pixels having the first polarization and a second pixel from the second array of image pixels having the second polarization.

Image data is converted to nonplanar image data for display on a nonplanar display, using a planar image graphics computer system, such as an OpenGL.RTM. system, which converts image data to planar image data for display on a planar display.

A plurality of vertices of the image data are multiplied by the obtained transformation matrix, to produce transformed image data.

An array of image pixels is projected into a hemispherical projection having constant angular separation among adjacent image pixels, so that the array of image pixels may be projected onto hemispherical surfaces of varying radii without requiring spatial distortion correction of the array of image pixels. The array of pixels is preferably projected radially from the center of a dome onto a spherical inner surface of the dome. The hemispherical projection may be tilted so that the array of pixels is projected onto one of a plurality of selectable positions on the inner dome surface. The projection system preferably includes at least three collimating lenses having a common ratio of index of refraction to dispersion. The projection system projects an array of image pixels from the image source into a hemispherical surface at a projection angle of at least 160 degrees, notwithstanding that the lenses are separated from the image by a separation distance which is at least six times the image size. Accordingly, hemispherical optical projection systems and methods are provided which can work with domes of many sizes and varying audience configurations, and which do not require spatial correction or color correction of the hemispherical image to be projected.

A multi-piece dome is constructed from a plurality of rigid panels and configured to receive a hemispherical optical projection on a truncated spherical inner surface. The inner view surface has a predetermined retroreflectivity. The multi-piece dome is lightweight, portable, self-supporting, and easily assembled, disassembled and transported from one location to another.
