The smartphone's sleekly designed body features a breakthrough, industry-first aurora optical coating, which uses layers upon layers to create a 180-degree infinite tangent plane
that plays with reflection, refraction, interference and diffraction of light beams, resulting in an ever-changing aurora color effect that shimmers from Electric Blue, Digital Green, to Deep Purple.
To perceive force feedback to the normal direction, users must be provided force feedback from a tangent plane
on touching area (surface contact) as shown in Figure 2.
Choose a point in the saddle-shaped weld; dihedral angle of the point on saddle weld is the angle between the cylinder's tangent plane
through this point and the pipe's tangent plane
his dervishes through each illumination angle-- tangent plane
Given the abovementioned condition, all rest system wave trajectories through a given point, [r.sub.k0], lie instantaneously in the tangent plane
at that point to the sphere of radius [r.sub.k0].
In this case, the calculation accuracy can be improved, because the local Cartesian coordinate systems which are established on the tangent plane
to the element surface at Gauss points can adapt to the curved element surface better.
Now for p [member of] S, the plane [p.sup.[sigma]] is the tangent plane
[T.sub.p]S, extended to infinity, that is, the projective closure [bar.[T.sub.p]S] of the tangent plane
in the analytic sense.
Liquid crystal molecules are oriented within the tangent plane
of the shell.
The principal curvatures [k.sub.1] and [k.sub.2] of the surface at [P.sub.0] are the maximum and minimum values of k(T) as T ranges over all directions in the tangent plane
. The mean curvature of the surface at [P.sub.0] is H = ([k.sub.1] + [k.sub.2])/2 and a surface is minimal if H = 0 at every point on the surface.
Space map projections already established are the Space Oblique Mercator, the space azimuth projection based on the tangent plane
as the projection plane, and the space cylindrical projection based on a cylindrical surface as the projection plane.
Thus, [partial derivative]Y contains no flat faces and no corners, and has a unique tangent plane
at each point.
And the deformation of the coating which is between two adjacent asperities located on different tangent plane
decreases with the increscent spacing of these two asperities.
