A power conversion unit includes a power converter and a controller coupled to the secondary or output stage of the power converter. The power conversion unit is configured to generate an output test voltage or current during a pre-start test period of the power converter, where the output test voltage or current is monitored to determine a converter fault condition. A method of operating a power conversion unit is also included.

In a computer system, a first electronic data processor is communicatively coupled to a first memory space and a second memory space. A second electronic data processor is communicatively coupled the second memory space and to a network interface device. The second electronic data processor is capable of exchanging data across a network of one or more computers via the network interface device. A video processor is adapted to combine video data from the first and second electronic data processors and transmit the combined video data to a display terminal for displaying the combined video data in a windowed format. The computer system is configured such that a malware program downloaded from the network and executing on the second electronic data processor is incapable of initiating access to the first memory space.
