Fire Screen
A fire screen or fireguard began as a form of furniture that acted as a shield between the occupants of a room and the fireplace, and its primary function was to reduce the discomfort of excessive heat from a log fire. Early firescreens were generally shaped as flat panels standing on attached feet, or as adjustable shield-shaped panels mounted on tripod table legs. Firescreens in the modern home have become decorative shields of sheet metal, glass, or wire mesh that can be placed in front of a fireplace opening to protect the room from open flames and flying embers that may be emitted by the fire. Fire screens were used to cover the fireplace when nothing was burning inside it, and make it look more decorative. Types of fire screen The ''three-panel'' fire screen, which covers the fireplace almost completely, has two side panels angled away from the central panel. It is an effective way of providing decoration in a room. The ''horse screen'', or ''cheval screen'' (cheval is the ...

Jet Blast Deflector
A jet blast deflector (JBD) or blast fence is a safety device that redirects the high energy exhaust from a jet engine to prevent damage and injury. The structure must be strong enough to withstand heat and high speed air streams as well as dust and debris carried by the turbulent air. Without a deflector, jet blast can be dangerous to people, equipment, vehicles and other aircraft.Morrison, Rowena. ''ASRS Directline'', Issue Number 6, August 1993"Ground Jet Blast Hazard."Retrieved on November 13, 2009. Jet blast deflectors range in complexity from stationary concrete, metal or fiberglass fences to heavy panels that are raised and lowered by hydraulic arms and actively cooled. Blast deflectors can be used as protection from helicopter and fixed-wing aircraft propwash. At airports and jet engine service centers, jet blast deflectors can be combined with sound-deadening walls to form a ground run-up enclosure within which a jet aircraft engine can safely and more quietly be teste ...

Shields (Star Trek)
In the ''Star Trek'' fictional universe, shields refer to a 23rd and 24th century technology that provides starships, space stations, and entire planets with limited protection against damage. They are sometimes referred to as ''deflectors'', '' deflector shields'', ''screens'', (the latter during ''Star Trek: The Original Series''). Types of shields include ''navigational deflectors''. History The term 'shields' first appears in the ''Star Trek'' episode "Balance of Terror", in which they were deployed, albeit to little effect, by a Federation outpost under attack from a Romulan Warbird. The first depicted use by a starship was in the ''Star Trek'' episode "Arena", in which the USS ''Enterprise'' raises its 'screens' after being attacked by an alien warship although the term 'shields' is not used in this episode. Shields are not mentioned during the earlier seasons of the ''Star Trek: Enterprise'' series, starships instead using "polarized hull plating" to make their hull mo ...

Wind Deflector
A convertible or cabriolet () is a passenger car that can be driven with or without a roof in place. The methods of retracting and storing the roof vary among eras and manufacturers. A convertible car's design allows an open-air driving experience, with the ability to provide a roof when required. A potential drawback of convertibles is their reduced structural rigidity (requiring significant engineering and modification to counteract the effects of removing a car's roof). The majority of convertible roofs are of a folding construction framework with the actual top made from cloth or other fabric. Other types of convertible roofs include retractable hardtops (often constructed from metal or plastic) and detachable hardtops (where a metal or plastic roof is manually removed and often stored in the trunk). Terminology Other terms for convertibles include cabriolet, cabrio, drop top, drophead coupé, open two-seater, open top, rag top, soft top, spider, and spyder. Consistenc ...
