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

second floor bridge‚ with the third floor walkway set off to the side several meters away from the other two. Construction difficulties led to a flawed design change that doubled the load on the connection between the fourth floor walkway support beams and the tie rods carrying the weight of both walkways. This new design could barely handle the dead load weight of the structure itself‚ much less the weight of the spectators standing on it. The connection failed and both walkways crashed one on top

were known as monochrome monitors and they did not use to have high quality displays. The displays that we see on the monitors are caused by the electrons directed on a phosphor coating on the screen by the cathode gun of the picture tube. To put it simply‚ the computer monitor comprises of a display device along with the circuitry required to form a display using the signals sent by an external source. The computer monitor receives the signals sent by the CPU of the PC and displays the same on the

is for construction managers to have a basic understanding of structural design. Had the construction manager on this Hartford Civic Center job understood the need for a structural engineer I might not be writing this paper. How he overlooked the deflection is shocking‚ that is a huge red light to get some structural help‚ especially on a job of this magnitude. In looking at the construction process a little broader than that of the construction manager; everyone involved‚ from the architect and engineer

essentially of a movable iron-core coil mounted on a pivot between the poles of a permanent magnet. When current flows through the coil‚ it creates a torque which causes the pointer to deflect. The amount of current through the coil determines the deflection of the pointer‚ which is registered on a scale attached to the meter movement. 2. What device is used to extend the range of the DC ammeter and how is it connected to the basic meter? The analog DC ammeter measures the current through a particular
