A typical HUD contains three primary components: a projector unit, a combiner, and a video generation computer. [3] 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 display, or liquid crystal display at its focus.
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal—provided by an external ("offboard") source—as it reflects off the target [1] [2] (in contrast to active radar homing, which ...
Manual command to line of sight (MCLOS or MACLOS) [1] is a method for guiding guided missiles. With an MCLOS missile, the operator must track the missile and the target simultaneously and guide the missile to the target. Typically the missile is steered with a joystick, and its path is observed through a periscope-type telescopic sight.

Video Core Next is AMD's successor to both the Unified Video Decoder and Video Coding Engine designs, [1] which are hardware accelerators for video decoding and encoding, respectively. It can be used to decode, encode and transcode ("sync") video streams, for example, a DVD or Blu-ray Disc to a format appropriate to, for example, a smartphone.
These usually combine a segmented anode plate with either just a Frisch grid [2] or an active electron-multiplication element like a gas electron multiplier. [3] These newer TPCs also depart from the traditional geometry of a cylinder with an axial field in favour of a flat geometry [ 2 ] or a cylinder with a radial field.
Target indicators falling over Berlin during a raid on the city. Target indicators, also known as target markers or TI's for short, were flares used by the RAF's Bomber Command during World War II. TIs were normally dropped by Pathfinders onto the target, providing an easily seen visual aiming point for the following "main force" of bombers to ...
