Abstract: Displaying analysis information about a portfolio across several charts and tables becomes more meaningful when the properties and behavior of a selected group of securities, or a pertinent field, is displayed in multiple charts and tables showing different parameters and functions of the selected group of securities, or unifying field. The selection of one group of securities in one chart or table may either highlight or filter that same selected group of securities across all displayed charts and tables. Moreover, selecting a different grouping scheme for one chart or table causes the display of the modified grouping scheme in all other charts and tables. Furthermore, based on the resulting information in the charts and tables the user may select different groups of securities, directly from the charts and tables, to be included in, excluded from, or have set constraints in subsequent analysis.

Abstract: A security device for securing secondary data storage devices having different levels of data security. The security device has an access to a plurality of primary and secondary storage devices, switches configured to separately enable and disable read and write operations to each of the plurality of storage devices, where at least two secondary storage devices cannot have their write access enabled at the same time. Further, the security device has a control circuit adapted to control the switches, and software that controls the switches in a manner that is transparent to the user. In one embodiment the operating system of the computing system resides on a separate storage device that is write protected when switching to a low level security storage device, the computing system and its operating system are ACPI compliant, and ready ACPI states are used in conjunction with switching the primary storage.
