Abstract: Apparatuses, systems, methods, and techniques relating to engine start/stop functionality are disclosed. Automatic engine start/stop controls can be disabled during engine operating conditions in which one or more combustion parameters indicate a lack of combustion stability in one or more cylinders of the engine. Engine start/stop controls are enabled when the one or more combustion parameters satisfy combustion parameter conditions indicating combustion stability in the one or more cylinders.

Abstract: A port card employable in a cell switch including a host computer having a processor and a bus for interconnecting a plurality of port cards and a method of switching cells in the cell switch. The port card includes: (1) bus master circuitry for gaining control of the bus to allow the port card to place cells to be switched in the cell switch on the bus and (2) interface circuitry, coupled to the local memory and the bus master circuitry, that places the cells on the bus when the bus master circuitry has gained control of the bus, the cells communicated directly from the interface circuitry to another port card in the cell switch via the bus. The processor (or, more generally, the host computer) is relieved of having to participate directly in switching the cells.
