The second may use a conical projection system.

With a conical projection on the tangent sphere, we get a spherical sinusoid : .

To create the map was used a conical projection as Lambert (LCC).

The characteristic of such device is that it is provided with a conical projection with two side grooves which makes the positioning into the ear steady.

the plane conical projection (the centre of the projection being on the axis and the plane of projection being perpendicular to this axis) of a circular helix (theorem of Théodore Olivier).

Examples are the Mercator projection (as shown in figure_mercator_projection) and the Lambert Conformal Conic projection.

Conic projections work as though a cone of paper has been placed on the Earth.

uvula - A conic projection at the back of the soft palate, covered by mucous membrane.
