Abstract: Disclosed is an integrated uninterruptable power supply (UPS) for a computer powered by a commercial power supply. The uninterruptable power supply is operative to feed power from a normal power supply to a first load to be operated at a first DC voltage and a second DC voltage that is lower than the first DC voltage. If a characteristic of the normal power supply is deviated from a defined value, the UPS of the present invention will continue feeding power from a battery power supply to the first load. The uninterruptable power supply includes a power supply unit, having an output connected to the first load, for converting a voltage of the normal power supply to the first DC voltage and for outputting the same. The UPS also includes a first voltage converter having an input connected to the battery and an output connected to the first load, for converting an output voltage of the battery to the second DC voltage and for outputting the same.

Abstract: A graphical user interface for a computer system has a toolbar with associated items and a menu bar having at least one pulldown menu with associated items, and provides a visual correspondence between items on the pulldown menu and items on the toolbar. The visual correspondence can be provided when a graphical pointer is placed over an item on the pulldown menu, and when a graphical pointer is placed over an item on the toolbar. The visual correspondence may be provided by highlighting the item on the toolbar, by providing a ghost image of the item on the toolbar, or by providing a ghost image of the pulldown menu. The invention retains current user interaction with toolbars and menu bars, and the novel dynamic linking of menu bar and toolbar items extends the functionality of the GUI without increasing visual complexity.
