Taximeter
A taximeter or fare meter is a mechanical or electronic device installed in taxicabs and auto rickshaws that calculates passenger fares based on a combination of distance travelled and waiting time. Its shortened form, "taxi", is also a metonym for the hired cars that use them. History The modern taximeter was invented by Germany, German Friedrich Wilhelm Gustav Bruhn in 1891, and the List of Daimler cars, Daimler Victoria—the world's first meter-equipped (and gasoline-powered) taxicab—was built by Gottlieb Daimler in 1897. Taximeters were originally mechanical and mounted outside the cab, above the driver's side front wheel. Meters were soon relocated inside the taxi, and in the 1980s electronic meters were introduced. k constant Constant expressed in pulses per kilometre which represents the number of pulses the taximeter must receive in order to correctly indicate a distance traveled of one kilometre.

Taxicab
A taxi, also known as a taxicab or simply a cab, is a type of vehicle for hire with a Driving, driver, used by a single passenger or small group of passengers, often for a non-shared ride. A taxicab conveys passengers between locations of their choice. This differs from public transport where the pick-up and drop-off locations are decided by the service provider, not by the customers, although demand responsive transport and share taxis provide a hybrid bus/taxi mode. There are four distinct forms of taxicab, which can be identified by slightly differing terms in different countries: * Hackney carriages, also known as public hire, hailed or street taxis, licensed for hailing throughout communities * Private hire vehicles, also known as minicabs or private hire taxis, licensed for pre-booking only * Taxibuses, also come in many variations throughout the Developing country, developing countries as Share taxi#United States, jitneys or jeepney, operating on pre-set routes typified ...

Mobile Data Terminal
A mobile data terminal (MDT) or mobile digital computer (MDC) is a computerized device used in emergency services, public transport, taxicabs, package delivery, roadside assistance, and logistics, among other fields, to communicate with a central dispatcher. They are also used to display mapping and information relevant to the tasks and actions performed by the vehicle such as CAD drawings, diagrams and safety information. Mobile data terminals feature a screen on which to view information and a keyboard or keypad for entering information, and may be connected to various peripheral devices. Standard peripherals include two-way radios and taximeters, both of which predate computer-aided dispatching. MDTs may be simple display and keypad units, intended to be connected to a separate black-box or AVL (see below) computer. While MDTs were originally thin clients, most have been replaced with fully functional PC hardware, known as MDCs (Mobile Digital Computers). While the MDC term ...

North American Taximeter (cropped)
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek ''boreas'' "north wind, north" which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

German Inventions
German inventions and discoveries are ideas, objects, processes or techniques Invention, invented, innovated or Discovery (observation), discovered, partially or entirely, by Germans. Often, things discovered for the first time are also called inventions and in many cases, there is no clear line between the two. Germany has been the home of many List of German inventors and discoverers, famous inventors, discoverers and engineers, including Carl von Linde, who developed the modern refrigerator. Ottomar Anschütz and the Max Skladanowsky, Skladanowsky brothers were early pioneers of History of film, film technology, while Paul Gottlieb Nipkow, Paul Nipkow and Karl Ferdinand Braun laid the foundation of the television with their Nipkow disk and cathode-ray tube (or Braun tube) respectively. Hans Geiger was the creator of the Geiger counter and Konrad Zuse built the first fully automatic digital computer (Z3 (computer), Z3) and the first commercial computer (Z4 (computer), Z4). Such ...

Tachometer
A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a axle, shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common. The word comes . Essentially the words tachometer and speedometer have identical meaning: a device that measures speed. It is by arbitrary convention that in the automotive world one is used for engine revolutions and the other for vehicle speed. In formal engineering nomenclature, more precise terms are used to distinguish the two. History The first tachometer was described by Bryan Donkin in a paper to the Royal Society of Arts in 1810 for which he was awarded the Gold medal of the society. This consisted of a bowl of mercury constructed in such a way that centrifugal force caused the level in a central tube to fall when it rotated and brought down the level in a narrower t ...

Speedometer
A speedometer or speed meter is a gauge (instrument), gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards. Other vehicles may use devices analogous to the speedometer with different means of sensing speed, eg. boats use a pit log, while aircraft use an airspeed indicator. Charles Babbage is credited with creating an early type of a speedometer, which was usually fitted to locomotives. The electric speedometer was invented by the Croats, Croat Josip Belušić in 1888 and was originally called a velocimeter. History The speedometer was originally patented by Josip Belušić (Giuseppe Bellussich) in 1888. He presented his invention at the Exposition Universelle (1889), 1889 Exposition Universelle in Paris. His invention had a pointer and a magnet, using eddy current, electricity to work. German inven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
