Journal gas bearing for curved surfaces
Optimizing bearing length and permissible axis curvature alleviates distortion of film gap of gas lubricated journal bearing in deployment mechanisms. Required bearing length is divided into two shorter bearings interconnected by links which allow satisfactory conformity with the bent, load-carrying member.
Redmon, J. W.↗
Foil bearing support for high-speed rotor
High speed rotors are supported initially by flexible metal foil and then on an air film generated by a self-acting hydrodynamic effect. The flexibility of the bearing enables it to conform and deflect locally, wear is less severe, self-alignment and accommodation of thermal distortion is permitted.

Calculation of incompressible fluid flow through cambered blades
Conformal mapping technique yields linear, approximate solutions for calculating flow of an incompressible fluid through staggered array of cambered blades for the cases of flow with partial cavitation and supercavitation. Lift and drag coefficients, cavitation number, cavity shape, and exit flow conditions can be determined.

Prevention of cracking of soldered joints in electronic assemblies
Printed circuit board design allows for thermal stressing of the soldered joints during many thermal cycles. Components' leads should be cleaned, tinned, and freed of particles that prevent solder adherence, have a thin conformal coating, and have an air space between the coating and the body of the component.

Self-forming shim or gasket for mounting heavy equipment
Soft, cross-serrated aluminum shims are used as mating gaskets between uneven surfaces. Under pressure, the aluminum flows to conform with surface irregularities, forming a plane of uniform bearing.

Ultra-flexible biomedical electrodes and wires
Soft, flexible electrode conforms to body contour during body motion. It is fabricated from an elastomer impregnated with a conductive powder which can be configured into any required shape, including a wire shape to connect the electrode directly to an electrical instrument or to a conventional metallic wire.
