Latest Patents

One of Kement's latest patents is titled "System and method for operating a system with redundant peripheral bus controllers." This inventive system effectively hides redundant paths to peripheral devices from the operating system by reporting a single "virtual" path to the peripheral buses over the PCI bus. The virtual path includes at least a virtual peripheral bus controller and a virtual video controller. The system informs the operating system that the real controllers are located on another PCI bus, connected to a PCI-to-PCI bridge. An I/O system manager selects one of the actual paths to manage communications with the peripheral devices, maintaining the controllers on the unselected path in standby mode. This ensures that if a failure occurs, the I/O system manager can perform a fail-over operation, allowing the peripheral devices to continue operating seamlessly. The operating system remains unaware of the controller failure, as it continues to recognize the virtual path as valid. Additionally, the system allows for hot swapping of PCI bridges and devices through selective FET isolation.

Another significant patent is the "Hot plug switch mechanism," which includes a card chassis and a motherboard featuring a power bus and multiple connectors for circuit boards. Each connector has a separate power switch that can be opened or closed. The mechanism incorporates actuator assemblies that close the corresponding switch when a connector is connected to a circuit board. Each power switch is preferably a Hall Effect switch, with an actuator assembly that includes a magnet to facilitate the connection.
