	Angular velocity - Wikipedia, the free encyclopedia
		With constant angular acceleration, the angular velocity conforms to the rotational equations of motion, equivalent to the standard linear equations of motion under constant linear acceleration.
		In the case of pure circular motion, the angular velocity is equal to linear velocity divided by the radius.
		In the case of generalized motion, the linear velocity is replaced by its component perpendicular to r, viz.

	Dynamic splinting component - Patent 4790300
		Another object of this invention is to provide a dynamic splint component that is intended to be mounted upon the forearm and wrist of a patient for the purpose of applying a perpendicular force to the back of the hand, thereby to draw the hand upwardly as it flexes the wrist.
		Component 10' is nearly identical with component 10, except that it is designed to be secured to the dorsal or top side of the wrist and forearm rather than to the underside.
		One feature of component 10, as mounted to the wrist and hand in the manner just described, is that as the hand is moved downward toward a rest position, tension force 52 and its longitudinal component 54 increase, but the perpendicular component 53 decreases toward zero.

	External Reflection from a Water Surface (Site not responding. Last check: 2007-10-05)
		Light is a transverse electromagnetic wave, meaning that it consists of mutually perpendicular oscillatory electric and magnetic fields which are both perpendicular to the direction of propagation.
		In particular, if light is randomly polarized (natural sunlight) the average electric field components in all directions are the same, and the total reflectance is the average of the parallel and perpendicular reflectances.
		Of special interest is the fact that the reflectance for the parallel component nearly vanishes at some intermediate angle of incidence.

	Guzik - Magnetic Recording Systems and Measurements Chapter 7
		When perpendicular head and media are used, the media grains are oriented in the "depth" of the medium and their magnetization is pointing either "up" or "down".
		In the case of perpendicular recording, the head is sensitive to media magnetization, therefore the uniformly magnetized media region generates constant read-back voltage of a given polarity in the read sensor.
		For perpendicular medium, a well-defined square-wave read-back signal is expected, since the output of the GMR sensor is proportional to the medium magnetization level (Figure 7.2).

	Caltrans Online Training-Highway Noise Measurements and Instrumentation
		To derive equivalent wind conditions for highway noise measurements, it is necessary to first resolve the wind vector - that is, wind speed and direction - into components that are parallel and perpendicular to the highway as shown in the illustration.
		If this component blows from the highway to the receiver as shown, the wind vector component is positive by convention and is called a downwind component.
		A wind vector component that blows from the receiver towards the highway is negative and is called an upwind component.

	Apparatus for developing electrostatic latent image - Patent 4941019
		The magnetization is such that a perpendicular component of the magnetic field (the component of the magnetic field perpendicular to the surface of the rotatable member) provides the maximum flux density point at or adjacent the center of the developing zone.
		The perpendicular magnetic field component magnetically confines the developer on the outer periphery of the rotatable member in the developing zone to form a brush so as to transfer the developer to the image bearing member.
		The magnetic flux density of the perpendicular component gradually decreases toward the opposite ends of the developing zone, and correspondingly, the tangential component of the magnetic field (the component of the magnetic field in the tangential direction of the outer periphery of the rotatable member) gradually increases in its density.

		We then look for a second component, perpendicular (“orthogonal” or “uncorrelated”) to the first, in such a way that maximum variances are extracted from the remaining 40%.
		The components have to be perpendicular (orthogonality) The first component has to extract as much as variance as possible from the original variables, the second component as much as possible from the remaining variance, etc. until all variance is used up.

		Charged particle moving perpendicular to a uniform magnetic field If a charged particle is initially moving perpendicular to a uniform magnetic field, the magnitude of the magnetic force on it is constant and is perpendicular to both the velocity and the field.
		The perpendicular component determines the radius of the circle in which the particle travels; the parallel component does not change, so the path of the particle is a helix.
		It states that the current through a surface bounded by a closed path is proportional to the component of the magnetic field parallel to the path multiplied by the length of the path.

	Field at a Charged Surface (Site not responding. Last check: 2007-10-05)
		If the lines of the electric field at the surface of the object were not perpendicular to the surface we could resolve the force vectors resulting from the interaction of the electrons with the field, into a perpendicular component and a component tangent to the surface.
		But any force on electrons tangent to the surface is going to move them to a different position on the surface, violating the principle that they were already in their minimum energy configuration.
		Therefore the lines of the electric field must be everywhere perpendicular to the surface.

		The intensity of the reflected beam relative to that of the incident beam (the "reflectance"), again depends on the angle of incidence and the direction of polarization of the light, as shown below.
		At normal incidence the reflectance is identical (about 2%) to the case of external reflection, for both the parallel and perpendicular polarization components.
		But while the reflectance of the perpendicular component increases monatonically with the angle of incidence, the reflectance for the parallel component first decreases to zero before increasing.

	Perception: ECVP 2002 abstracts (Site not responding. Last check: 2007-10-05)
		The motion perceived in a field of moving bars is initially perpendicular to the orientation of the bars, rotating to the actual direction of motion within about 200 ms (Lorenceau et al, 1993 Vision Research 33 1207 - 1217).
		Here, we demonstrate the existence of a new class of motion stimuli where the component of motion that is perpendicular to a moving contour dominates perceived motion, even when there is no aperture, and intrinsic terminators are entirely visible and moving in a different direction.
		If several such bar stimuli are placed in two different orientations with respect to their common actual motion, they appear to break into two sets, each moving along its respective perpendicular component.

	Pitch Angle (Site not responding. Last check: 2007-10-05)
		Their helical trajectories result from the fact that their motion is both parallel and perpendicular to the magnetic field, which exerts a force on the perpendicular component of their velocity that causes them to move around the field lines ("cyclotron" motion) as well as along them.
		The angle between the direction of the magnetic field and a particle's spiral trajectory is referred to as the "pitch angle," which in a non-uniform magnetic field changes as the ratio between the perpendicular and parallel components of the particle velocity changes.
		As particles spiraling along geomagnetic field lines get closer to the Earth, the strength of the magnetic field increases, which causes the parallel component of the particles' velocity to decrease (with a corresponding increase in the perpendicular component).
