Head-up display

A head-up display or heads-up display—also known as a HUD—is any transparent display that presents data without requiring users to look away from their usual viewpoints. The origin of the name stems from a pilot being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments. A HUD also has the advantage that the pilot's eyes do not need to refocus to view the outside after looking at the optically nearer instruments.

Although they were initially developed for military aviation, HUDs are now used in commercial aircraft, automobiles and other, mostly professional applications.

Overview

A typical HUD contains three primary components: a projector unit, a combiner, and a video generation computer.

The projection unit in a typical HUD is an optical collimator setup: a convex lens or concave mirror with a Cathode Ray Tube, light emitting diode, or liquid crystal display at its focus. This setup (a design that has been around since the invention of the reflector sight in 1900) produces an image where the light is collimated, i.e. the focal point is perceived to be at infinity.

Undisputed (DMX album)

Undisputed is the seventh studio album by American rapper DMX. It was released on September 11, 2012 on Seven Arts Music.

Background

On October 11, 2011 DMX performed at the 2011 BET Hip Hop Awards. He stated that he has been working "nonstop, every day" on the new album, and plans to release it before December 2012. During a performance at New York's Santos Party House on December 25, 2011, DMX stated that the new album will be entitled Undisputed and would be released on March 26, 2012. This was later confirmed by DMX via his official Twitter account, where he also confirmed that its first single is scheduled for release in January 2012. A video for a new track entitled "Last Hope" was released via Internet on September 24, 2011. This was later released on his The Weigh In EP and omitted from the final release of Undisputed.

Seven Arts Entertainment Inc. recently purchased David Michery's music assets, which included some of DMX's music. DMX's had announced that Undisputed will be released on March 27, 2012. However it was later revealed that DMX did not plan to release the album on that date, and that date was one forced upon him by the record label. The release date for the album was set for June 26, 2012. However, DMX announced in Detroit, Michigan on June 9, 2012, that due to the record label, the date will be pushed back again. It was then scheduled for release on August 28, 2012. Later, an official press release from the label pushed the back date to September 11, 2012. He donated the album's first week sales to the victims of the September 11 attacks. The album features only one male guest appearance by rapper Machine Gun Kelly. The album was also supposed to feature Sean Kingston, Tyrese and Busta Rhymes, but none of these artists were featured in the final cut.
