	Device and a method for calibration of an industrial robot - Patent 6418774
		The inclinometer is placed on a plane of reference on one of the links, and generates a signal, which is a measure of the angle between the plane of reference of the link and the vertical line.
		Examples of sources of error are mounting errors between the adapter plate and the plane of reference of the robot, mounting errors between the inclinometer plate and the adapter plate, and errors of tolerance of the adapter plate.
		A first plane of reference on the robot is arranged on the base 1, a second plane of reference is arranged on the first arm 2, a third plane of reference is arranged on the second arm 4, and a fourth and last plane of reference is arranged on the tool attachment 6.

		Each is characterized by a specific plane of reference which determines a great circle when projected onto the celestial sphere, and by a specific reference point on that great circle.
		As the name suggests, the plane of the Earth's equator is chosen as the plane of reference.
		The reference point on the celestial equator is defined with the aid of another plane, the plane of the Earth's orbit, called the ecliptic.

		S-parameters for a device (in particular their angles), refer to fixed reference planes at each port, whether you are dealing with measured or simulated data.
		This is the equivalent of moving the reference planes by 6 centimeters away from the device (recall that electromagnetic energy moves almost exactly 30 centimeters in one nanosecond, it's a Microwaves101 rule of thumb).
		The total reference plane adjustment (0.034 nanoseconds) is roughly equal to the average group delay of the part.

	Plane of reference - Definition, explanation (Site not responding. Last check: 2007-10-24)
		In celestial mechanics, the plane of reference is the plane from which orbital elements are defined.
		Specifically, the inclination and the longitude of the ascending node are the two main orbital elements that are measured with respect to the plane of reference.
		On the plane of reference, a zero-point must be defined from which the angles of longitude are measured.

		This causes the plane line to be not straight and therefore the player is not “on plane.” With that said, anytime you swing the club too far out-to-in or in-to-out you are swinging off plane.
		The plane line sits parallel to and just inside of the target line because this is where the shaft of the club would meet the ground when the clubface is soled behind the golf ball.

	Systems and methods for providing a reference plane for mounting an acetabular cup during a computer-aided surgery ...
		Some navigational references may have markers or fiducials that are traced by an infrared sensor to determine the position and orientation of the reference and thus the position and orientation of the associated instrument, item, implant component or other object to which the reference is attached.
		In addition, the processor is capable of defining a reference plane for a surgical procedure associated with an acetabular component, based at least in part on detecting the array associated with the platform using the sensor.

		Reference ellipsoids are defined by semi-major (equatorial radius) and semi-minor (polar radius) axes.
		The geodetic longitude of a point is the angle between a reference plane and a plane passing through the point, both planes being perpendicular to the equatorial plane.
		The X-axis is defined by the intersection of the plane define by the prime meridian and the equatorial plane.

		As a result they were punished, cursed to exist forever on the ethereal plane without permanent shape or form, and therefore long to become flesh and blood again, as is foretold in the future final conflict between the Angels and the Demons.
