  • Device diagnostic system
    Patent number: 7350115
    Abstract: A device management system includes a backplane, a device that communicates via the backplane and that stores identification information, a management module that receives the identification information and that provides a diagnostic module that corresponds to the identification information, and a controller associated with the device. The controller provides the identification information to the management module, receives the diagnostic module from the management module, and outputs diagnostic information for the device that is obtained via the diagnostic module.

  • Battery backup unit system and interface
    Patent number: 6509657
    Abstract: A battery backup unit can be used to supply backup power to a computer. The battery backup unit includes a charge circuit that is connected to the computer's power supply unit. The charge circuit is also connected to a battery pack that includes a battery. The charge circuit converts an input high DC voltage signal supplied by the power supply unit to a charging signal. The charging signal can be used to charge the battery in the battery pack. The battery backup unit also includes a discharge circuit that is connected to the power supply unit and the battery pack. The discharge circuit converts a battery signal received from the battery pack to an output high DC voltage signal. The output high DC voltage signal can be fed into the power supply unit in order to drive the power supply unit if there is an indication that the AC power input to the power supply unit is inadequate to drive the computer.
