A thermal conduction structure is integrated into a multi-layer circuit board to thermally couple a power electronic device to a heatsink while electrically isolating the power electronic device from the heatsink. The thermal conduction structure includes a stack of alternatingly insulative and conductive layers, a first set of vertical vias that thermally and electrically join the power electronic device to a first set of conductive layers, and a second set of vertical vias that thermally and electrically join the heatsink to a second set of conductive layers that are interleaved with the first set of conductive layers.

An engine data acquisition and control system measures cylinder pressure at a high degree of resolution and then processes it for portions of the combustion cycle of interest for performing combustion calculations. The data are utilized to calculate combustion parameters, and the combustion parameters may be utilized to control the engine's fuel and/or spark timing/duration, and other variables affecting the combustion process. The system architecture provides for acquisition of very large amounts of data without unduly loading the CPU.

Cylinder-pressure-based electronic engine controller and method

A method/system for measuring cylinder pressures of an internal combustion engine includes a crank angle sensor utilized to generate pressure readings at known angular intervals. Additional time-based pressure measurements are taken in selected angular windows between a pair of the angle-based pressure readings. Because the angle-based pressure measurements and the time-based pressure measurements occur at known times, the pressure as a function of the crank angle for the time-based pressure measurements can be determined. The cylinder pressure measurements can be utilized to calculate combustion parameters used for closed-loop engine control of fuel supply or other engine inputs.
