WEDway is a people mover system using linear induction motor (LIM) technology to propel vehicles along a pair of steel rails. [1]This system was developed by WED Enterprises (now Walt Disney Imagineering) and has been installed at places such as Walt Disney World Resort's Magic Kingdom (as Tomorrowland Transit Authority PeopleMover) and George Bush Intercontinental Airport (as Subway) in ...
An ellipsograph is a mechanism that generates the shape of an ellipse. One common form of ellipsograph is known as the trammel of Archimedes . [ 1 ] It consists of two shuttles which are confined to perpendicular channels or rails and a rod which is attached to the shuttles by pivots at adjustable positions along the rod.
A leg mechanism (walking mechanism) is a mechanical system designed to provide a propulsive force by intermittent frictional contact with the ground. This is in contrast with wheels or continuous tracks which are intended to maintain continuous frictional contact with the ground.
In more recent years, computer programs have been used to find and calculate more precise approximations of the perimeter of an ellipse. In an online video about the perimeter of an ellipse, recreational mathematician and YouTuber Matt Parker, using a computer program, calculated numerous approximations for the perimeter of an ellipse.

The iliopsoas is the prime mover of hip flexion, and is the strongest of the hip flexors (others are rectus femoris, sartorius, and tensor fasciae latae). [3] The iliopsoas is important for standing, walking, and running. [2] The iliacus and psoas major perform different actions when postural changes occur.
The popliteus muscle in the leg is used for unlocking the knees when walking, by laterally rotating the femur on the tibia during the closed chain portion of the gait cycle (one with the foot in contact with the ground). In open chain movements (when the involved limb is not in contact with the ground), the popliteus muscle medially rotates the ...
Robert Gilmour "R. G." LeTourneau (/ l ə t ˈ ər n oʊ /; November 30, 1888 – June 1, 1969), born in Richford, Vermont, was a prolific inventor of technologies related to earthmoving machinery, and founder of LeTourneau Technologies and LeTourneau University. [1]
This is to allow the patient to breathe easily while the rest of the device is secured. Following the bottom torso strap the leg straps are secured. These may be applied in a "criss-cross" fashion (according to the KED users' manual this is the most commonly used method), or applied by securing them to their respective sides.
