Duke University Medical Center Patient Rapid Transit
Duke University Medical Center Patient Rapid Transit or Personnel Rapid Transit (PRT) was an automated people mover system located at the Duke University Medical Center in North Carolina, in the United States. The system was in operation from 1979 to 2009. The PRT was notable for having cars propelled by a linear induction motor and suspended on a bed of compressed air similar to a hovercraft. Uniquely, the cars could move sideways, as well as backwards and forwards. The proclaimed "horizontal elevator" system was designed by Otis Elevator Company during the 1970s, installed beginning in 1977 and opened on December 8, 1979. The PRT had three driverless Otis Hovair vehicles which had a hinged-window at each end for emergency exit. The concrete guideway was built as double track, connecting the three stations at Duke South, Duke North and Parking Garage II via a tunnel under Erwin Road. Decommissioning The 0.25-mile (<400 m) section between Duke South and Duke North was closed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emergency Exit
An emergency exit in a building or other structure is a special exit used during emergencies such as fires. The combined use of regular and emergency exits allows for faster evacuation, and emergency exits provide alternative means of evacuation if regular exits are inaccessible. Emergency exits must: * Be clearly marked (usually with signage that is normally illuminated, or is illuminated by a backup power source if central power fails) * Be in easily-accessible locations * Direct people to safe areas (usually outside) * Be regularly maintained and free of obstructions (they may not be used for storage) * Be secured to prevent unauthorized entry during normal operations An emergency exit's path usually ends in an outward-opening door with a crash bar with exit signs pointing to it. It is usually a door to an area outside of the building, but may also lead to an adjoining, fire-isolated structure with clear exits of its own. A fire escape is a special kind of emergency ...

Linear Induction Motors
A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects, whereas a conventional induction motor is arranged in an endless loop. Despite their name, not all linear induction motors produce linear motion; some linear induction motors are employed for generating rotations of large diameters where the use of a continuous primary would be very expensive. As with rotary motors, linear motors frequently run on a three-phase power supply and can support very high speeds. However, there are end-effects that reduce the motor's force, and it is often not possible to fit a gearbox to trade off force and speed. Linear induction motors are thus frequently less energy efficient than normal rotary motors for an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former People Mover Systems In The United States
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being used in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose cone to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until th ...

University People Mover Systems
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the Middl ...

Hospital People Mover Systems
A hospital is a healthcare institution providing patient treatment with specialized health science and auxiliary healthcare staff and medical equipment. The best-known type of hospital is the general hospital, which typically has an emergency department to treat urgent health problems ranging from fire and accident victims to a sudden illness. A district hospital typically is the major health care facility in its region, with many beds for intensive care and additional beds for patients who need long-term care. Specialized hospitals include trauma centers, rehabilitation hospitals, children's hospitals, geriatric hospitals, and hospitals for specific medical needs, such as psychiatric hospitals for psychiatric treatment and other disease-specific categories. Specialized hospitals can help reduce health care costs compared to general hospitals. Hospitals are classified as general, specialty, or government depending on the sources of income received. A teaching hospital campus c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transportation In Durham, North Carolina
Transport (in British English) or transportation (in American English) is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipelines, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fuel docks and fuel stations), and seaports. Terminals may be used both for the interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack animals. Vehicles may include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
