The display has a normal viewing angle perpendicular to a surface of the display.

The display has a normal viewing angle perpendicular to a surface of the display.

It is a vector normal (i.e., perpendicular) to the loop.

The required angle for optimal viewing is nominally perpendicular to the plane of the display (i.e., normal), but is optionally selectable (by design of the holograms) to be an angle varies from the strict perpendicular.

Early Gothic architecture, the Decorated Style, the Perpendicular Style.

The target normal (140) is compared to the source normal (124).

Lateral-facing means facing perpendicular to the normal direction of travel of the vehicle.

The plate shall be perpendicular or practically perpendicular to the plane of symmetry of the tractor.

(Here, the word 'normal' is used in its mathematical sense of being perpendicular.)

The moveable element includes a perpendicular portion (104) oriented substantially perpendicular to the substrate.

(Here, the word "normally" means perpendicularly.)

A surface normal is a vector perpendicular to the surface at a given point.

The normal vector is a vector which is perpendicular to the surface at a given point.

Also, light emission may be normal or near-normal to the exit surface.

The angle at which the attenuator is held may be perpendicular or non perpendicular to the longitudinal axis of the sleeve.
