A vane display is a type of seven-segment display. Unlike LED and VFD segmented displays, vane displays are composed of seven physical surfaces (vanes), typically painted white, but occasionally other colors, such as yellow or fluorescent green. If a segment is to be displayed as "off", it will be rotated so that its edge faces forward, with the painted surface pointing away and not visible. A segment to be displayed as "on" will be rotated so that the painted surface is shown.
Vane displays operate in a similar manner to flip-disc displays, in that the segments are quickly moved using electromagnets. Some variants used where the display need not necessarily be changed quickly use electric motors to rotate the displays in and out of place.
Vane displays have been used in game shows and on scoreboards in sports arenas and stadiums. Like eggcrate displays, they are not washed out by bright lights such as those found in a television studio. Another benefit of the vane display is that if the power supply is lost, the display will continue to show whatever the last value was before power was cut. However, like flip-disc displays, if many elements must be changed at the same time, the flipping displays may present a significant amount of noise.
Examples
American and Canadian game shows have used vane displays to display contestants' scores or for countdown clocks. Prior to this, the slide display was more common.
The Oklahoma Turnpike Authority has used vane displays on several of their automatic toll collection baskets to display the toll due.
The New Jersey Turnpike previously used vane displays for all roadway speed limit signs; it was not uncommon to see them blank; VMS sign replacements now use a new electronic speed limit sign. Various other locations with variable speed limits also employ either this or eggcrate, flip-disc, or LED displays to display the current speed limit for the area.
A zoetrope is a pre-film animation device that produces the illusion of motion, by displaying a sequence of drawings or photographs showing progressive phases of that motion. A zoetrope is a cylindrical variant of the phénakisticope, an apparatus suggested after the stroboscopic discs were introduced in 1833. The definitive version of the zoetrope, with replaceable film picture film strips, was introduced as a toy by Milton Bradley in 1866 and became very successful.
The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, or the Eisenhower Interstate System, is a network of controlled-access highways that forms part of the National Highway System in the United States. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico.
Road transport or road transportation is a type of transport using roads. Transport on roads can be roughly grouped into the transportation of goods and transportation of people. In many countries licensing requirements and safety regulations ensure a separation of the two industries. Movement along roads may be by bike, automobile, bus, truck, or by animal such as horse or oxen. Standard networks of roads were adopted by Romans, Persians, Aztec, and other early empires, and may be regarded as a feature of empires. Cargo may be transported by trucking companies, while passengers may be transported via mass transit. Commonly defined features of modern roads include defined lanes and signage. Various classes of road exist, from two-lane local roads with at-grade intersections to controlled-access highways with all cross traffic grade-separated.
A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction.
A variable-message sign or message board, often abbreviated VMS, VMB, CMS, or DMS, and in the UK known as a matrix sign, is an electronic traffic sign often used on roadways to give travelers information about special events. Such signs warn of traffic congestion, accidents, incidents such as terrorist attacks, AMBER/Silver/Blue Alerts, roadwork zones, or speed limits on a specific highway segment. In urban areas, VMS are used within parking guidance and information systems to guide drivers to available car parking spaces. They may also ask vehicles to take alternative routes, limit travel speed, warn of duration and location of the incidents, inform of the traffic conditions, or display general public safety messages.
A display device is an output device for presentation of information in visual or tactile form. When the input information that is supplied has an electrical signal the display is called an electronic display.
The Kansas Turnpike is a 236-mile (380 km) controlled-access toll road that lies entirely within the US state of Kansas. It runs in a general southwest–northeast direction from the Oklahoma border to Kansas City. It passes through several major Kansas cities, including Wichita, Topeka, and Lawrence. The turnpike is owned and maintained by the Kansas Turnpike Authority (KTA), which is headquartered in Wichita.
A seven-segment display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.
In road transport, a lane is part of a roadway that is designated to be used by a single line of vehicles to control and guide drivers and reduce traffic conflicts. Most public roads (highways) have at least two lanes, one for traffic in each direction, separated by lane markings. On multilane roadways and busier two-lane roads, lanes are designated with road surface markings. Major highways often have two multi-lane roadways separated by a median.
Revolutions per minute is a unit of rotational speed for rotating machines. One revolution per minute is equivalent to 1/60 hertz.
The flip-disc display is an electromechanical dot matrix display technology used for large outdoor signs, normally those that will be exposed to direct sunlight. Flip-disc technology has been used for external destination signs on buses and trains across North America, Europe and Australia, as well as for variable-message signs on highways. It has also been used extensively on public information displays. A few game shows have also used flip-disc displays, including Canadian shows like Just Like Mom, The Joke's on Us and Uh Oh!, but most notably the American game show Family Feud from 1976 to 1995, and its British version Family Fortunes from 1980 to 2002. The Polish version of Family Feud, Familiada, still uses this board, which was bought from the Swedish version of the show.
The Newton disc, also known as the disappearing colour disc, is a well-known physics experiment with a rotating disc with segments in different colours appearing as white when it's spun rapidly about its axis.
Interstate 95 (I-95) is a part of the Interstate Highway System that runs north–south from Miami, Florida to Houlton, Maine. The highway enters Maine from the New Hampshire state line in Kittery and runs for 303 miles (488 km) to the Canada–United States border at Houlton. It is the only primary Interstate Highway in Maine. In 2004, the highway's route between Portland and Gardiner was changed so that it encompasses the entire Maine Turnpike, a toll road running from Kittery to Augusta. As an Interstate Highway, all of I-95 in Maine is included in the National Highway System, a network of roads important to the country's economy, defense, and mobility.
Trashed is a television game show that ran on MTV from February 14 to July 23, 1994, with Chris Hardwick as host.
A split-flap display, or sometimes simply a flap display, is a digital electromechanical display device that presents changeable alphanumeric text, and occasionally fixed graphics.
This article briefly describes the components and systems found in jet engines.
A text display is an electronic alphanumeric display device that is mainly or only capable of showing text, or extremely limited graphic characters. This includes electromechanical split-flap displays, vane displays, and flip-disc displays; all-electronic liquid-crystal displays, incandescent eggcrate displays, LED displays, and vacuum fluorescent displays; and even electric nixie tubes.
A cam engine is a reciprocating engine where instead of the conventional crankshaft, the pistons deliver their force to a cam that is then caused to rotate. The output work of the engine is driven by this cam.
Terminology related to road transport—the transport of passengers or goods on paved routes between places—is diverse, with variation between dialects of English. There may also be regional differences within a single country, and some terms differ based on the side of the road traffic drives on. This glossary is an alphabetical listing of road transport terms.
Rotary atomizers use a high speed rotating disk, cup or wheel to discharge liquid at high speed to the perimeter, forming a hollow cone spray. The rotational speed controls the drop size. Spray drying and spray painting are the most important and common uses of this technology.
