Embodiments provide a slanted bump magnetic shield in a perpendicular write head and a method of making the shield. A hybrid-electric transmission is located in the engine compartment and an inverter system controller module is supported on an equipment shelf extending between the hybrid electric transmission and the hood. The transmitted beam preferably is focused using a cylindrical lens, providing a beam tightly focused in one dimension and unfocused in a second dimension. Joint replacement components can be modular and would benefit from a PVES to decrease wear and damp impact between modular parts of a single component. A first heat exchanger receives the second compressed refrigerant stream and generates a cooled stream.
