Multi-primary color display

Multi-primary color (MPC) display is a display that can reproduce a wider gamut color than conventional displays. In addition to the standard RGB (Red Green and Blue) color subpixels, the technology utilizes additional colors, such as yellow, magenta and cyan, and thus increases the range of displayable colors that the human eye can see.[1][2]

Sharp's Quattron is the brand name of an LCD color display technology that utilizes a yellow fourth color subpixel.[3][4] It is used in Sharp's Aquos LCD TV product line, particularly in models with screens 40 inches across and larger.[5]

Adaptive compliant wing

An adaptive compliant wing is a wing which is flexible enough for aspects of its shape to be changed in flight.An adaptive compliant wing designed by FlexSys Inc. features a variable-camber trailing edge which can be deflected up to ±10°, thus acting like a flap-equipped wing, but without the individual segments and gaps typical in a flap system. The wing itself can be twisted up to 1° per foot of span. The wing's shape can be changed at a rate of 30° per second, which is ideal for gust load alleviation. The development of the adaptive compliant wing is being sponsored by the U.S. Air Force Research Laboratory. Initially, the wing was tested in a wind tunnel, and then a 50-inch (1.3 m) section of wing was flight tested on board the Scaled Composites White Knight research aircraft in a seven-flight, 20-hour program operated from the Mojave Spaceport. Control methods are proposed.Adaptive compliant wings are also investigated at ETH Zurich in the frame of the Smart airfoil project.

Atomtronics

Atomtronics is an emerging sub-field of ultracold atomic physics which encompasses a broad range of topics featuring guided atomic matter waves. The systems typically include components analogous to those found in electronic or optical systems, such as beam splitters and transistors. Applications range from studies of fundamental physics to the development of practical devices.

Automated restaurant

Automated restaurant or robotic restaurant is a restaurant that uses robots to do tasks such as delivering food and drinks to the tables and/or to cook the food.

Bionic contact lens

Bionic contact lenses are devices that, it is proposed by the manufacturers and developers, could provide a virtual display that could have a variety of uses from assisting the visually impaired to video gaming. The device will have the form of a conventional contact lens with added bionics technology in the form of augmented reality, with functional electronic circuits and infrared lights to create a virtual display allowing the viewer to see a computer-generated display superimposed on the world outside.

Closed ecological system

Closed ecological systems (CES) are ecosystems that do not rely on matter exchange with any part outside the system.

The term is most often used to describe small manmade ecosystems. Such systems are scientifically interesting and can potentially serve as a life support system during space flights, in space stations or space habitats.In a closed ecological system, any waste products produced by one species must be used by at least one other species. If the purpose is to maintain a life form, such as a mouse or a human, waste products such as carbon dioxide, feces and urine must eventually be converted into oxygen, food, and water.

A closed ecological system must contain at least one autotrophic organism. While both chemotrophic and phototrophic organisms are plausible, almost all closed ecological systems to date are based on a phototroph such as green algae.

Cryoprotectant

A cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e. that due to ice formation). Arctic and Antarctic insects, fish and amphibians create cryoprotectants (antifreeze compounds and antifreeze proteins) in their bodies to minimize freezing damage during cold winter periods. Cryoprotectants are also used to preserve living materials in the study of biology and to preserve food products.

For years, glycerol has been used in cryobiology as a cryoprotectant for blood cells and bull sperm, allowing storage at liquid nitrogen temperatures. However, glycerol cannot be used to protect whole organs from damage. Instead, many biotechnology companies are researching the development of other cryoprotectants more suitable for such uses. A successful discovery may eventually make possible the bulk cryogenic storage (or "banking") of transplantable human and xenobiotic organs. A substantial step in that direction has already occurred. Twenty-First Century Medicine has vitrified a rabbit kidney to -135 °C with their proprietary vitrification cocktail. Upon rewarming, the kidney was successfully transplanted into a rabbit, with complete functionality and viability, able to sustain the rabbit indefinitely as the sole functioning kidney.

Ferroelectric liquid crystal display

Ferroelectric Liquid Crystal Display (FLCD) is a display technology based on the ferroelectric properties of chiral smectic liquid crystals as proposed in 1980 by Clark and Lagerwall.The FLCD did not make many inroads as a direct view display device. Manufacturing of larger FLCDs was problematic making them unable to compete against direct view LCDs based on nematic liquid crystals using the Twisted nematic field effect or In-Plane Switching. Today, the FLCD is used in reflective microdisplays based on Liquid Crystal on Silicon technology. Using ferroelectric liquid crystal (FLC) in FLCoS technology allows a much smaller display area which eliminates the problems of manufacturing larger area FLC displays. Additionally, the dot pitch or pixel pitch of such displays can be as low as 6 µm giving a very high resolution display in a small area. To produce color and grey-scale, time multiplexing is used, exploiting the sub-millisecond switching time of the ferroelectric liquid crystal.

These microdisplays find applications in 3D head mounted displays (HMD), image insertion in surgical microscopes and electronic viewfinders where direct-view LCDs fail to provide more than 600 ppi resolution.

Ferroelectric LCoS also finds commercial uses in Structured illumination for 3D-Metrology and Super-resolution microscopy. Some commercial products use FLCD.High switching speed allows building optical switches and shutters in printer heads.

Holographic display

A holographic display is a type of display that utilizes light diffraction to create a virtual three-dimensional image of an object. Holographic displays are distinguished from other forms of 3D imaging in that they do not require the aid of any special glasses or external equipment for a viewer to see the image.

Multi-function structure

Multi-function material is a composite material. The traditional approach to the development of structures is to address the loadcarrying function and other functional requirements separately. Recently, however, there has been increased interest in the development of load-bearing materials and structures which have integral non-load-bearing functions, guided by recent discoveries about how multifunctional biological systems work.

Ocean colonization

Ocean colonization or ocean colonisation is the theory and practice of permanent human settlement of oceans. Such settlements may be seasteads floating on the surface of the water, or exist as underwater habitats secured to the ocean floor, or in an intermediate position.One primary purpose of ocean colonization is the expansion of livable area. Other possible benefits include expanded access to undersea resources, novel forms of governance (for instance micronations), and new recreational activities.Lessons learned from ocean colonization may prove applicable to space colonization. The ocean may prove simpler to colonize than space and thus occur first, providing a proving ground for the latter. In particular, the issue of sovereignty may bear many similarities between ocean and space colonization; adjustments to social life under harsher circumstances would apply similarly to the ocean and to space; and many technologies may have uses in both environments.

Organic light-emitting transistor

An organic light-emitting transistor (OLET) is a form of transistor that emits light. These transistors have potential for digital displays and on-chip optical interconnects. OLET is a new light-emission concept, providing planar light sources that can be easily integrated in substrates like silicon, glass, and paper using standard microelectronic techniques.OLETs differ from OLEDs in that an active matrix can be made entirely of OLETs, whereas OLEDs must be combined with switching elements such as TFTs.

Plasma weapon

When discussing weapons in science fiction, a plasma weapon is a type of raygun that fires a stream, bolt(s), pulse or toroid of plasma (i.e. very hot, very energetic excited matter). The primary damage mechanism of these fictional weapons is usually thermal transfer; it typically causes serious burns, and often immediate death of living creatures, and melts or evaporates other materials. In certain fiction, plasma weapons may also have a significant kinetic energy component, that is to say the ionized material is projected with sufficient momentum to cause some secondary impact damage in addition to causing high thermal damage. In some fictions, like Star Wars, plasma is highly effective against mechanical targets such as droids. The ionized gas disrupts their systems.

Fictional plasma weapons are often visually analogous to real-life plasma torches that cut into materials for industrial use purposes; however, said torches currently only produce a plasma jet of several inches at most.

Pure fusion weapon

A pure fusion weapon is a hypothetical hydrogen bomb design that does not need a fission "primary" explosive to ignite the fusion of deuterium and tritium, two heavy isotopes of hydrogen used in fission-fusion thermonuclear weapons. Such a weapon would require no fissile material and would therefore be much easier to develop in secret than existing weapons. The necessity of separating weapons grade uranium (U-235) or breeding plutonium (Pu-239) requires a substantial and difficult-to-conceal industrial investment, and blocking the sale and transfer of the needed machinery has been the primary mechanism to control nuclear proliferation to date.

Quattron

Quattron is the brand name of an LCD color display technology produced by Sharp Electronics. In addition to the standard RGB (Red, Green, and Blue) color subpixels, the technology utilizes a yellow fourth color subpixel (RGBY) which Sharp claims increases the range of displayable colors, and which may mimic more closely the way the brain processes color information. The screen is a form of multi-primary color display, other forms of which have been developed in parallel to Sharp's version.The technology is used in Sharp's Aquos LCD TV product line, particularly in models with screens 40 inches across and larger. The technology, distinct from the product line, has been advertised featuring George Takei as the spokesperson in the debut commercial, in which he uses his catchphrase "Oh My". Another commercial had Takei advertising the 3-D model with the Minions from the 2010 movie

Despicable Me.

STEAM fields

STEAM fields are science, technology, engineering, art, and mathematics, or applied mathematics. STEAM is designed to integrate STEM subjects into various relevant education disciplines. These programs aim to teach students innovation, to think critically and use engineering or technology in imaginative designs or creative approaches to real-world problems while building on students' mathematics and science base. STEAM programs add art to STEM curriculum by drawing on design principles and encouraging creative solutions.

Screenless video

Screenless video is any system for transmitting visual information from a video source without the use of a screen. Screenless computing systems can be divided into three groups: Visual Image, Retinal Direct, and Synaptic Interface.

Twistronics

Twistronics is the study of how the angle (the twist) between layers of two-dimensional materials can change their electrical properties. Materials such as graphene have been shown to have vastly different electrical properties (ranging from non-conductive to superconductive) depending on the angle between the layers.
