A family of sliding vane rotary power devices provides an internal combustion engine, a pump, a compressor, a fluid-driven motor, an expander device, a fluid-driven pump, a compressor or a throttling device. The housing is of a 3D holding space formed by an end wall and a periphery. The unit provides gentle and uniform heating, with minimal heat loss and escape of volatile chemicals. The host device includes an application configured to interact with the process on the portable device. An interlevel dielectric layer disposed on the upper surface overlies the gate trench and the source region, and a metal layer in electrical contact with the source and body regions overlies the upper surface and the interlevel dielectric layer.
