  • Patent number: 5745669
    Abstract: A computer utility automatically monitors changes in configuration files stored on the computer hard disk. The recovery tool indicates to the user when changes are detected in the configuration files and provides the option to restore the configuration files to their state before they were changed if the computer system operates improperly. In addition, the recovery tool monitors selected application files for changes in the files or missing files, and prompts the user when a change is detected. The recovery tool also provides for monitoring of the CMOS memory which stores computer system operating functions and parameters. If possible corruption of the CMOS memory is detected, the recovery tool restores the contents of the CMOS to their proper state. Finally, the computer utility provides the option of making a bootable floppy diskette containing the computer system configuration.

  • Patent number: 4075715
    Abstract: A helmet useful for crew members of an aircraft from which they may be ejected at high speeds comprises a shell over which there is a visor housing containing a visor which can be pulled down over the face of the searer. An anti-lift device in the form of a flange protrudes from the visor housing and extends from a position near a forward side edge of the visor housing and passes around and across the top crown area to a position near the opposite forward side edge of the visor housing. The flange rises from a lowest elevation near the forward side edges to a highest elevation at the top crown area. The regions adjacent the forward side edges constitute wings at a negative angle of attack against wind blase and the region in the vicinity of the top crown area constitutes a spoiler producing turbulence to spoil upward lift.
