Microvision Inc. has the exclusive license to commercialize the VRD technology. This technology has many potential applications‚ from head-mounted displays (HMDs) for military/aerospace applications to medical society. The VRD projects a modulated beam of light (from an electronic source) directly onto the retina of the eye producing a rasterized image. The viewer has the illusion of seeing the source image as if he/she stands two feet away in front of a 14-inch monitor. In reality‚ the image is

depending on their stiffness relative to the framing in which they are used. Engineers consider some joints as pinned in their structural analysis‚ even though it is common knowledge that all joints exhibit some rotational constraint. For example beam-tocolumn joints made with a thin and non-extended end plate are actually semi-rigid but are modelled as frictionless pinned connections. Until recently there has been no reliable evidence that the idealisation of such joints is a safe building

that cools to become a strong joint‚ with pressure sometimes used in conjunction with heat‚ or by itself‚ to produce the weld. Different types of energy sources can be used for welding‚ including a gas flame‚ an electric arc‚ a laser‚ an electron beam‚ friction‚ and ultrasound. While often an industrial process‚ welding may be performed in many different environments‚ including open air‚ under water and in outer space. Welding is a potentially hazardous undertaking and precautions are required

transportation. Whether it’s a canyon‚ or a body of water‚ bridges allow travel over those gaps from one part of land to the other. The world would be forever changed without bridges. The five main types of bridges are arch bridges‚ truss bridges‚ beam bridges‚ suspension‚ and cable-stayed bridges. Arch bridges are bridges that use arch as a main structural support/component. Depending on how much weight is normally being applied on the bridge‚ they are made with one or more hinges. One of the more

They conducted the first official powered flight in 1903 on December 17. The plane was made of wooded beams with canvas stretched over them. The plane had two vertical wings with propellers behind them that pushed the plane through the sky. The pilot would sit on the wing and pull on ropes and pullies to steer the plane.

When a focused X-ray beam interacts with these planes of atoms‚ part of the beam is transmitted‚ part is absorbed by the sample‚ part is refracted and scattered‚ and part is diffracted. Diffraction of an X-ray beam by a crystalline solid is analogous to diffraction of light by droplets of water‚ producing the familiar rainbow. X-rays are diffracted by each mineral differently‚ depending on what atoms make up the crystal lattice and how these atoms are arranged. When an X-ray beam hits a sample and
