Dish Network, and their previously separated partner, EchoStar, have launched dozens of satellites over the past decade in order to provide direct broadcast satellite television services to their subscribers. While each satellite location, known as an “orbital location” provides services to a different region of the Earth, many of the orbital locations contain multiple satellites to increase available bandwidth and provide redundancy to cover any inoperable satellites in the area. Likewise, satellites in one orbital location can still provide service to satellite receivers in an area designated to a nearby Read More

LCD projectors work by using three liquid crystal panels, a lamp, a prism, and filters to create the image on the screen. The lamp provides white light that passes through a polarizing filter. Polarizing works by accepting light that is traveling on the same plane. All other light will be blocked. From the polarizing filter the light is then passed through a series of dichroic mirrors. Dichroic mirrors work by only allowing certain colors in the light spectrum to be reflected, while others pass through. The dichroic mirrors in LCD Read More
