Sunroof Deflector

Sunroof

A sunroof is a cutout in a car's (or truck's) roof that can be opened to provide fresh air and sun to the people inside. A sunroof can be made of the same metal as the rest of the roof, or it can be made of plastic and transparent (usually tinted), in which case it is customarily referred to as a moonroof. Moonroofs have a sliding shade in the interior that can be retracted, and were invented by the American Sunroof Company. Sunroofs can be manual or electric. Manual sunroofs usually work by flipping up to create a small opening around the edges, or being removed completely. Electric sunroofs either flip up and slide back on top of the roof, or down and into the roof. An electric sunroof will have access to close it manually if the motor or control circuitry fails.

Navigational Deflector

, an Ambassador class starship.]] In the Star Trek fictional universe, the navigational deflector is a device found on many Starfleet ships capable of warp travel, generally noticeable by its foremost location on many ships' engineering hulls and its soft blue glow. The navigational deflector is used while moving at faster-than-light speeds to prevent damage to ships' hulls from micrometeors and friction from the microscopic objects and extremely thin gas found in interstellar space. Deflectors accomplish the first goal through the use of powerful deflector/tractor beams extending several thousand kilometers fore of their ships, aimed automatically through use of the ships' long-range sensors. The deflection of smaller objects and stray atoms is done by largely static low-power deflector shields generated by the deflector. The beams and shields created by the deflector are often a source of subspace distortion and EM radiation, which can interfere with the operation of ships' sensors. Due to this, long-range sensor arrays are often placed circularly around navigational deflectors. This allows the sensors to look along the same axes of the beams and shields to reduce interference and also, because of their close proximity to the deflector, allows for the speedy receipt of data from them by the computer in control of the device. In combat, the navigational deflector forms the first layer of a starship's static defenses. It is almost useless against high-powered beam and missile weapons, but quite potent at blunting the assault of light and medium-powered weapons. The hardware used in navigational deflectors can be quickly reconfigured to produce a variety of particle streams and energy emissions, making them a sort of 'Swiss army knife' for Starfleet vessels and a convenient deus ex machina device for script writers. Such uses can be seen in ''Star Trek: First Contact'', where it was used to travel into the past and, later, reconfigured into an interplexing

Deflector Shield

A deflector shield is a fictional technology commonly found in science fiction. Typically, deflector shields (often referred to as simply "shields") are some form of energy field that is projected along the surface of, or into the space around, a starship, space station, planet, moon, or building. The concept goes back at least as far as the 1920s, in the works of E.E. 'Doc' Smith and others; and William Hope Hodgson's ''The Night Land'' (1912) has the Last Redoubt, in which the remnants of humanity shelter, protected by something very like one. Although fictional, deflector shields have some resemblance to real devices such as magnetic field generators. The abilities and exact functionality of deflector shields vary; in some works (such as in the Star Trek universe), deflector shields can stop both energy beams (e.g. phasers) and physical projectiles, both natural and artificial; in others, such as the Star Wars universe, there are multiple types of deflector shields -- so-called ray shields which are designed to stop energy beams (such as laser and blaster weapons), and particle shields which are designed to stop kinetic projectiles, missiles, bombs, etc. Deflector shields usually work by absorbing or dissipating the energy of the incoming attack; prolonged exposure to such attacks weakens the shield and eventually results in the shield's collapse, making the ship's hull (or building's walls, or planet's surface) vulnerable to attack. Larger deflector shield systems, or those powered by bigger energy sources, can absorb/dissipate more damage before failing -- so that larger starships, for example, can mount much stronger shields than a small, single-person starfighter, much in the way that a sea-going battleship has much thicker armor than a tiny patrol boat.

Deflector Shield

How a deflector shield could be made

If you emit a powerful magnetic field around a ship, and then fire "alpha" and "beta" radiation through, this would ionise all matter entaring, and would be deflected by the shield.

Smoke Deflectors

Smoke deflectors are plates attached to the front of a steam locomotive designed to lift smoke away from the locomotive so that the driver has better visibility unimpaired by drifting smoke. There are various styles of smoke deflectors.
