Abstract: A cluster of processing systems is provided wherein each processing system is set to operate at a unique operating frequency. Each unique frequency is set to differ from each other by at least a predetermined frequency differential or bandwidth. When clustered, the radiated emissions will not add. Rather, the RF energy is distributed over the predetermined frequency bandwidth and in so doing achieve a reduction of measured RF energy at any singular frequency. By using RF energy dispersal in systems consisting of aggregated processing elements as subsystems, the need for special or additional RF shielding is precluded. Current design and manufacturing techniques can continue to be used. Thus, reducing the overall cost of implementing aggregated systems.

Abstract: A computer has at least one adapter card slot for receiving an optional adapter card. A cover plate is rotatable hinged and has open and closed positions. In the closed position, the cover plate covers the adapter card slot and inhibits the insertion or removal of an adapter card. When the cover plate is raised into the open position, a tab on the back of the cover plate is rotated out of the slot of an optical switch, and the optical switch then signals circuitry to remove power and bus signals from the adapter card slot; thereby permitting the adapter card to be removed from or inserted into the slot without removing power to the entire computer. When the cover plate is returned to the closed position, the tab is reinserted into the slot of the optical switch, which in turn signals the circuitry to return power and bus signals to the adapter card slot.

Abstract: A hot-pluggable PCI adapter slot isolates the power from the adapter and the expansion slot signals from the system bus. MOSFETs with a gate drive controller are used to isolate power, and high speed FET switches isolate the signals. The wiring required to connect the bus to the bus switches and then to the adapter card is minimized by optimizing package size, pin count and trace lengths required for connection. The FET switches are embedded in the expansion PCI connector in series with the signal pins to the system PCB and the edge that connects the network to the finger on the adapter card.
