The present invention is an apparatus for providing an uninterruptible power supply for an electronic device. The apparatus includes an AC-to-DC power supply that receives an external AC voltage supply and outputs a DC voltage to the electronic device. The power supply includes a bridge rectifier that rectifies the AC voltage from the external AC voltage supply, a boost power factor correction (PFC) converter that boosts the rectified voltage, and a line isolated DC-to-DC converter that changes the boosted voltage to the operating voltage range of the electronic device. The apparatus also includes an uninterruptible power supply (UPS) subsystem that contains, a controller that monitors the external AC voltage supply for interruptions, and a high voltage isolated DC-to-DC (HVDC) converter that supplies high voltage DC power directly to the PFC converter if the controller detects an interruption in the external AC voltage supply.

Uninterruptable power supply

A network interface is described in which a single computer bus is split over a long distance into two or more inter-communicating buses. On one bus, processing and applications are provided and on the other remote bus, peripheral and local controllers are provided. The buses communicate through a series of: bridge, FPGA, FPGA and bridge. Between the FPGAs, a communication path provides long distance communication.

Split computer architecture to separate user and processor while retaining original user interface

Split computer architecture

A split computer ( ) comprises a main module ( ) remotely connected by external PCI bus ( ) to a input/output (I/O) or extension module ( ). The main module ( ) comprises a processor ( ) and an external PCI bus first interface ( ). The input/output (I/O) module comprises one or more input and/or output device controllers and an external PCI bus second interface. The external PCI bus connects the external bus first interface of the main module with the external bus second interface of the input/output (I/O) module. The main module executes application programs, maintains user configurations, and maintains application configurations. Yet since the main module is located remotely, e.g., at a data center ( ), the both security and centralized management are realized using existing hardware and software. The input/output (I/O) module has a relative small footprint and primarily performs input and output operations.
