Quad Cinema
The Quad Cinema is New York City's first small four-screen multiplex theater. Located at 34 West 13th Street in Greenwich Village, it was opened by entrepreneur Maurice Kanbar, along with his younger brother Elliott S. Kanbar in October 1972. It has been described as "one of the oldest independent cinemas in the city" and "a vibrant center for art house films." History In the late 1960s, Maurice Kanbar, an inventor and real estate investor, purchased a six-story loft in Manhattan with plans to create an off-Broadway theater. After those plans fell through, he found himself with a large block of unused ground floor space. Kanbar believed a movie theater with multiple small auditoriums rather than a few larger ones could be profitable even with smaller audiences at most screenings. In October 1972, he and his younger brother, Elliott S. Kanbar, opened the Quad, New York City's first four-screen movie theater, and what Kanbar has called "the East Coast's first multiplex".

Wheelchair Tennis
Wheelchair tennis is one of the forms of tennis Adaptive sport, adapted for wheelchair users. The size of the court, net height and rackets are the same, but there are two major differences from pedestrian tennis: athletes use specially designed wheelchairs, wheelchairs, and the ball may bounce up to two times, where the second bounce may also occur outside the court. Wheelchair tennis has been played at all four Grand Slam (tennis), Grand Slams since 2007 and is one of the sports played at the Summer Paralympics. There are three categories, Men, Women, and Quads; each category has singles and doubles tournaments. The Quad, the newest division, is for players that have substantial loss of function in at least one upper limb, but may include various disabilities besides quadriplegia. The division is sometimes called Mixed, especially at the Paralympic Games. Quad players often tape the rackets to their hand, to compensate for loss of function, and some players are allowed to use ...

Quadrilateral Security Dialogue
The Quad is a grouping of Australia, India, Japan, and the United States that is maintained by talks between member countries. The grouping follows the "Tsunami Core Group" and its "new type of diplomacy" developed in response to the 2004 2004 Indian Ocean earthquake and tsunami, Indian Ocean earthquake and tsunami. It was initiated in 2007 by Japanese Prime Minister Shinzo Abe, with the support of Australian Prime Minister John Howard, Indian Prime Minister Manmohan Singh and U.S. Vice President Dick Cheney. The dialogue was paralleled by Military exercise#Types, joint military exercises of an unprecedented scale, titled Malabar (naval exercise)#2002–2007, Exercise Malabar. The diplomatic and military arrangement was widely viewed as a response to increased Chinese economic and military power. The partnership is known formally as the "Quad," not the "Quadrilateral Security Dialogue," noting its nature as a diplomatic, not security, partnership. The "Quadrilateral Security Di ...

Quad (figure Skating)
A quadruple jump or quad is a figure skating jump with at least four (but fewer than five) revolutions. All quadruple jumps have four revolutions, except for the quadruple Axel, which has four and a half revolutions. The quadruple toe loop and quadruple Salchow are the two most commonly performed quads. Quadruple jumps have become increasingly common among World and Olympic level men's single skaters, to the point that not performing a quad in a program has come to be seen as a severe handicap. This phenomenon is often referred to as the "quad revolution". Since 2018, quadruple jumps have also become an increasingly common feature of women's skating, although they are not allowed under the International Skating Union ("ISU") rules in the ladies' short program. The first person to land a ratified quadruple jump in competition was Canadian Kurt Browning in 1988. Japanese skater Miki Ando became the first female to do so, in 2002.

Railroad Speeder
A speeder (also known as a section car, railway motor car, putt-putt, track-maintenance car, crew car, jigger, trike, quad, trolley, inspection car, or draisine) is a small railcar used around the world by track inspectors and work crews to move quickly to and from work sites. Although slow compared to a train or car, it is called ''speeder'' because it is faster than a human-powered vehicle such as a handcar. Motorized inspection cars date back to at least 1895, when the Kalamazoo Manufacturing Company started building gasoline-engined inspection cars. In the 1990s, many speeders were replaced by pickup trucks or sport utility vehicles with additional flanged wheels that could be lowered for travelling on rails, called " road–rail vehicles" or hi-rails for "highway-railroad". Speeders are collected by hobbyists, who refurbish them for excursions organized by the North American Railcar Operators Association in the U.S. and Canada and the Australian Society of Section Car O ...

Chairlift
An elevated passenger ropeway, or chairlift, is a type of aerial lift, which consists of a continuously circulating steel wire rope loop strung between two end terminals and usually over intermediate towers. They are the primary on-hill transport at most ski areas (in such cases referred to as 'ski lifts'), but are also found at amusement parks and various tourist attractions. Depending on carrier size and loading efficiency, a passenger ropeway can move up to 4,000 people per hour, and the fastest lifts achieve operating speeds of up to or . The two-person double chair, which for many years was the workhorse of the ski industry, can move roughly 1,200 people per hour at rope speeds of up to . The four person detachable chairlift ("high-speed quad") can transport 2,400 people per hour with an average rope speed of . Some bi- and tri-cable elevated ropeways and reversible tramways achieve much greater operating speeds. Design and function A chairlift consists of numerous c ...

Quadcopter
A quadcopter, also called quadrocopter, or quadrotor is a type of helicopter or multicopter that has four rotors. Although quadrotor helicopters and convertiplanes have long been flown experimentally, the configuration remained a curiosity until the arrival of the modern unmanned aerial vehicle or drone. The small size and low inertia of drones allows use of a particularly simple flight control system, which has greatly increased the practicality of the small quadrotor in this application. Design principles Each rotor produces both lift and torque about its center of rotation, as well as drag opposite to the vehicle's direction of flight. Quadcopters generally have two rotors spinning clockwise (CW) and two counterclockwise (CCW). Flight control is provided by independent variation of the speed and hence lift and torque of each rotor. Pitch and roll are controlled by varying the net centre of thrust, with yaw controlled by varying the net torque. Unlike conventional hel ...

Jeffery Quad
The Jeffery Quad, also known as the Nash Quad or Quad is a four-wheel drive, 1-ton rated truck that was developed and built by the Thomas B. Jeffery Company from 1913 in Kenosha, Wisconsin, and after 1916 by Nash Motors, which acquired the Jeffery Company. Production of the Quad continued unchanged through 1928. The Quad introduced numerous engineering innovations. Its design and durability proved effective in traversing the muddy, rough, and unpaved roads of the times. The Quad also became one of the most successful vehicles in World War I. The Quad was produced in large numbers by Jeffery and Nash, as well as under license by other truck makers. Development The United States Army needed to replace the four-mule teams used to haul standard one-and-a-half-ton loads with a truck and requested proposals in late 1912. The company began development by purchasing and examining a new Four Wheel Drive Auto Company (FWD) truck, but found it to be unacceptable and sold the vehicle t ...

Quadracycle
A quadracycle (also spelled quadricycle) is a four-wheeled human-powered land vehicle. It is also referred to as a quadcycle, pedal car or four-wheeled bicycle amongst other terms. Quadracycles have been in use since 1853 and have grown into several families of vehicles for a variety of purposes, including tourist rentals, pedal taxis, private touring, mountain and industrial use. Nomenclature There is no consensus amongst manufacturers of four-wheeled, human-powered vehicles as to what this class of vehicles should be called, although ''quadracycle'' is the most commonly used term. Manufacturers who do refer to their products by class of vehicle call them: *Quadracycle - 11 manufacturers *Four-wheel bicycle - 7 manufacturers *Quadricycle - 5 manufacturers *Quadcycle - 3 manufacturers *Pedal car - 2 manufacturers *Quad - 2 manufacturers In addition there are single manufacturers who call them Go-kart, Car, Car-Bike, Ecological car, Human Powered Vehicle, Pedal Kart, Quadri ...

Tandem Bicycle
A tandem bicycle or twin is a bicycle (occasionally a tricycle) designed to be ridden by more than one person. The term tandem refers to the seating arrangement (fore to aft, not side by side), not the number of riders. Patents related to tandem bicycles date from the mid-1880s. Tandems can reach higher speeds than the same riders on single bicycles, and tandem bicycle racing exists. As with bicycles for single riders, there are many variations that have been developed over the years. Terminology The term tandem refers to the seating arrangement (fore to aft, not side by side), not the number of riders. A bike with two riders side by side is called a sociable. Tandem bicycles are sometimes called "Daisy Bells". This is in reference to " Daisy Bell (Bicycle Built for Two)" which is a popular song, written in 1892 by British songwriter Harry Dacre, with the well-known chorus, "Daisy, Daisy / Give me your answer, do. / I'm half crazy / all for the love of you", ending with ...

Quad Bike
An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), a quad bike or quad (if it has four wheels), as defined by the American National Standards Institute (ANSI), is a vehicle that travels on low-pressure tires, has a seat that is straddled by the operator, and has handlebars, similar to a motorcycle. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. It is street-legal in some countries, but not in most states, territories and provinces of Australia, the United States, and Canada. By the current ANSI definition, ATVs are intended for use by a single operator, but some ATVs, referred to as tandem ATVs, have been developed for use by the driver and one passenger. The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slower speeds. Although most are equipped with three or four wheels, six or eight wheel (tracked) models exist and have existed historically ...
