Mattel

Currently, it is headquartered in El Segundo, California. They also were used as a portal to another world in Lewis Carroll's Through the Looking Glass. Mattel serves as the parent company for American Girl (formerly Pleasant Company) and Fisher-Price. In Tlön, Uqbar, Orbis Tertius, a fictional heresiarch declares that "mirrors and copulation are abominable, since they both multiply the numbers of men.". In 1996, Mattel purchased Tyco Toys which was the third largest toy manufacturer at the time. In Dreamtigers, he writes of fearing that his reflection would move independently or change shape before his eyes. In 1993, Mattel merged with the Fisher-Price toy company. Mirrors, along with labyrinths, figure prominently in the work of Argentine writer Jorge Luis Borges, who often used them as symbols of infinity, impersonation, and illusion.

An independent audit of Mattel, released on November 3, 1975, revealed that company officials had fabricated press releases and financial information to "maintain the appearance of continued corporate growth." In 1999, the ill-advised purchase of a major software publisher, TLC, for $3.6 billion dollars led to the CEO, Jill Barad, being ousted (See Brøderbund.). Illuminated rotating disco balls covered with small mirrors are used to cast moving spots of light around a dance floor. The company became publicly owned in 1960. Mirrors are often used in magic to create an illusion. With the success of their dollhouse accessories, the company turned its attention to toys. The hall of mirrors, commonly found in amusement parks, is an attraction in which a number of distorted mirrors are used to produce unusual reflections of the visitor. The company originally produced picture frames and dollhouse accessories from picture frame scraps. This technique was used by Native American tribes and numerous militaries to transmit information between distant outposts.

are:. The signal can be used over long distances, possibly up to 60 kilometres on a clear day. Current members of the board of directors of Mattel Inc. With the sun as light source, a mirror can be used to signal, by variations in the orientation of the mirror. . A decorative reflecting sphere of thin metal-coated glass, working as a reducing wide-angle mirror, is sold as a Christmas tree decoration called a bauble. Elliott Handler's wife Ruth Handler would later become president, and is credited with establishing the Barbie product line for the company in 1959. Mirrors, typically large and unframed, are frequently used in interior decoration to create an illusion of space, and amplify the apparent size of a room.

It was founded in 1945 by Elliot Handler and Harold "Matt" Matson (hence the name "matt-el"). Its purpose is to split a beam of light so that half passes straight through, while the other half is reflected — this is useful for interferometry. It produces products including Barbie dolls, board games, and in the early 1980s, video game consoles. The same type of mirror, when used in an optical instrument, is called a half-silvered mirror or beam splitter. Mattel Inc. NYSE: MAT is the world's largest toy company based on revenue. It may be used to observe criminal suspects or customers (to watch out for theft). The Barbie and Ken dolls are named after the Handler children. Persons on the dark side see through it - it looks like a transparent window.

Scene It. Persons on the brightly lit side see their own reflection - it looks like a normal mirror. UNO. It is used between a dark room and a brightly lit room. Othello (Reversi). It is a sheet of glass coated with a layer of metal only a few dozen atoms thick, allowing some of the light through the surface (from both sides). Chatty Cathy (1959-1965, 1969-1971, 1998, 2001). A one-way mirror, also called two-way mirror, reflects about half of the light and lets the other half pass.

See 'n Say. Use of a large number of mirrors in a confined space can act to satisfy people's desire for satisfication of their ego, as in the hall of mirrors in the Palace of Versailles. Popples plush toys. Other uses of mirrors in hedonistic acts include the classic 'mirror on the ceiling' for use during sex (see The Eagles' Hotel California), and the use of mirrors for 'cutting' and snorting cocaine. Matchbox. upskirt. Major Matt Mason (1966 - 1970). A mirror is sometimes used for voyeurism, e.g.

Masters of the Universe action figures. High quality flat mirrors are essential for making corner reflectors, which are used for emergency location, and even laser ranging to the Moon. Justice League Unlimited. Mirrors are also sometimes used as part of security systems, so that a single video camera can show more than one angle at a time. Hot Wheels. Rounded (convex) mirrors are sometimes placed at road junctions, and corners of places such as parking lots or stores, allowing people to see around corners to avoid crashing into other vehicles or shopping carts. Cabbage Patch Kids (1994-2000). There exist rear view sunglasses, of which the left end of the left glass and the right end of the right glass work as mirrors.

Big Jim. Some motorcycle helmets have a built-in so-called MROS (Multiple Reflective Optic System): a set of reflective surfaces inside the helmet which together function as a rear-view mirror [1]. Barbie and Ken dolls. Rear-view mirror are applied in and on vehicles (such as cars, or bicycles), to allow drivers to see other vehicles coming up behind them. Aquarius. In astronomy, adaptive optics is a technique to measure variable image distortions and adapt a mirror accordingly on a timescale of milliseconds, to compensate for the distortions. Intellivision. Such mirrors are often used in lasers.

Kathy White. The best mirrors of this type can reflect >99.999% of the light (in a narrow range of wavelengths) which is incident on the mirror. John Vogelstein. By careful choice of the type and thickness of the dielectric layers, the range of wavelengths and amount of light reflected from the mirror can be specified. Craig Sullivan. These are glass (or sometimes other material) substrates on which one or more layers of dielectric material are deposited, to form an optical coating. G. For scientific optical work, dielectric mirrors are often used.

Christopher Sinclair. The reflectivity as a function of wavelength depends on both the thickness of the coating and on how it is applied. Ronald Sargent. For instance, aluminum mirrors are commonly coated with magnesium fluoride. Andrea Rich. Mirror surfaces are sometimes given thin film overcoatings both to retard degradation of the surface and to increase their reflectivity in parts of the spectrum where they will be used. Tully Friendman. A hot mirror is the opposite, the coating preferentially reflects infrared.

Eckert, Chairman. A cold mirror is made by using a transparent substrate and choosing a coating material that is more reflective to visible light and more transmissive to infrared light. Robert A. This is exploited in some optical work to make cold mirrors and hot mirrors. Michael Dolan. The reflectivity of the mirror coating can be measured using a reflectometer and depends on the wavelength of light as well as the metal. Eugene Beard. Front silvered mirrors have to be resurfaced occasionally to keep their quality.

Bob Normille, Senior VP, General Counsel and Secretary. A protective overcoat is usually applied before the mirror is removed from the vacuum, because the coating otherwise begins to corrode as soon as it is exposed to oxygen and humidity in the air. Alan Kaye, Senior VP of Human Resource. The coatings are typically applied by vacuum deposition. Debrowski, Executive VP of World Wide Operations. They reflect 90% to 95% of the incident light when new. Thomas A. All of these coatings are easily damaged and require special handling.

Stockton, Executive VP of International. Some of them use silver, but most are aluminum, which is more reflective at short wavelengths than silver. Bryan G. Telescopes and other precision instruments use front silvered mirrors, where the reflecting surface is placed on the front surface of the glass, which gives better image quality. Brothers, President American Girl Brands. This may be to check physical appearance (including clothing, make-up, hair, etc.) or to control applying make-up, shaving, cutting hair, fixing one's tie, etc. Ellen L. A mirror is used for inspecting parts of one's body which are difficult or impossible to see directly, such as the face, neck or the whole body.

Neil Friedman, President Mattel Brands. The "back side" of the mirror is often painted black to completely seal the metal from corrosion. Kevin Farr, CFO. This type of mirror reflects about 80% of the incident light. Eckert, Chairman of the Board, CEO (since May 2000). They are back silvered, where the reflecting surface is viewed through the glass sheet; this makes the mirror durable, but lowers the image quality of the mirror due to extraneous reflections from the front surface of the glass. Robert A. Most modern mirrors consist of a thin layer of aluminium deposited on a sheet of glass.

Early mirrors were usually a sheet of polished metal, often silver or copper, for example the Aranmula kannadi. In either case, an observer farther from the mirror than you will see your normal orientation directly and in the mirror before you turn, and will then observe that you put your right hand where your left was if you rotate the usual way, or your head where your feet were if you stand on your head. If one rotated about a horizontal axis parallel to the mirror surface, one would appear upside down. The question is sometimes asked, "Why does the mirror reverse left to right and not top to bottom?" The answer is that one has rotated (as is most comfortable) about a vertical axis to face the mirror.

When the rotation is so obvious that it is not worth mentioning, the second component in this decomposition of the effect of the mirror is sometimes emphasized, by saying that a mirror "reverses left and right". In particular, if one looks at one's image in a vertical mirror in left-right orientation, the image corresponds to a rotation by 180° about the vertical axis in the mirror, combined with a reflection in one's approximate symmetry plane. In this case the image of the person is in normal standing orientation and vertically in a normal position, at a horizontally different position and with an orientation rotated about a vertical axis, the latter except if the mirror is parallel to the approximate symmetry plane of the person. This is the case iff the mirror is vertical.

The image is the most realistic if it is still vertical, i.e., if the rotation is about a vertical axis. We can apply this to the image in a mirror of, say, a standing person, because people have approximate bilateral symmetry. For an object with approximate reflection symmetry, a reflection in some mirror plane corresponds to a combination of:. That is, if the beam of light is shining on a mirror's surface at a 30° angle from vertical, then it reflects from the point of incidence at a 30° angle from vertical in the opposite direction.

A beam of light reflects off a mirror at an angle of reflection that is equal to its angle of incidence. Note that spherical concave and convex mirrors do not have a single focal point, as often described in high school physics text books (see spherical aberration in lens (optics) and aberration in optical systems). Finally, there are convex mirrors, where a parallel beam becomes divergent, with the apparent intersection occurring behind the mirror. There are also parabolic concave mirrors, where a parallel beam of light becomes a convergent beam, whose rays intersect in the focus of the mirror.

In a plane mirror, a parallel beam of light changes its direction as a whole, whilst still remaining parallel; the images formed by a plane mirror are virtual images, of the same size as the original object (see mirror image). . The most common use is in the home for personal grooming but mirrors are also used in scientific apparatus such as telescopes and lasers, and in industrial machinery. The best known example is the plane mirror.

A mirror is a surface with good specular reflection that is smooth enough to form an image. a reflection in the approximate symmetry plane of the object (due to the assumption this is a minor change). a translation if the mirror is parallel to the symmetry plane of the object, and otherwise a rotation about the line of intersection of the two planes by an angle which is twice the angle between the two planes.
