ClearType is Microsoft's implementation of subpixel rendering technology in rendering text in a font system. ClearType attempts to improve the appearance of text on certain types of computer display screens by sacrificing color fidelity for additional intensity variation. This trade-off is asserted to work well on LCD flat panel monitors.
A Climax locomotive is a type of geared steam locomotive built by the Climax Manufacturing Company, of Corry, Pennsylvania. These had two steam cylinders attached to a transmission located under the center of the boiler, which sent power to driveshafts running to the front and rear trucks. Some 1,000-1,100 were built in three classes between 1888 and 1928.
A stereoscope is a device for viewing a stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image.
A windscreen wiper or windshield wiper is a device used to remove rain, snow, ice, washer fluid, water, or other debris from a vehicle's front window. Almost all motor vehicles, including cars, trucks, buses, train locomotives, and watercraft with a cabin—and some aircraft—are equipped with one or more such wipers, which are usually a legal requirement.
Pepper's ghost is an illusion technique, used in the theatre, cinema, amusement parks, museums, television, and concerts, in which an image of an object off-stage is projected so that it appears to be in front of the audience.
The phenakistiscope was the first widespread animation device that created a fluid illusion of motion. Dubbed Fantascope and Stroboscopische Scheiben by its inventors, it has been known under many other names until the French product name Phénakisticope became common. The phenakistiscope is regarded as one of the first forms of moving media entertainment that paved the way for the future motion picture and film industry. Similar to a GIF animation, it can only show a short continuous loop.
The valve gear of a steam engine is the mechanism that operates the inlet and exhaust valves to admit steam into the cylinder and allow exhaust steam to escape, respectively, at the correct points in the cycle. It can also serve as a reversing gear. It is sometimes referred to as the "motion".
The word cryptex is a neologism coined by the author Dan Brown for his 2003 novel The Da Vinci Code, denoting a portable vault used to hide secret messages. It is a word formed from Greek κρυπτόςkryptós, "hidden, secret" and Latin codex; "an apt title for this device" since it uses "the science of cryptology to protect information written on the contained scroll or codex". The first physical cryptex was created by Justin Kirk Nevins in 2004.
A squeegee or squilgee is a tool with a flat, smooth rubber blade, used to remove or control the flow of liquid on a flat surface. It is used for cleaning and in printing.
A shoji is a door, window or room divider used in traditional Japanese architecture, consisting of translucent sheets on a lattice frame. Where light transmission is not needed, the similar but opaque fusuma is used. Shoji usually slide, but may occasionally be hung or hinged, especially in more rustic styles.
In a reciprocating engine, the cylinder is the space in which a piston travels.
A drive shaft, driveshaft, driving shaft, tailshaft, propeller shaft, or Cardan shaft is a component for transmitting mechanical power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them.
A rotary snowplow or rotary snowplough is a piece of railroad snow removal equipment with a large circular set of blades on its front end that rotate to cut through the snow on the track ahead of it. The precursor to the rotary snowplow was the wedge snowplow.
Herbert Akroyd-Stuart was an English inventor who is noted for his invention of the hot bulb engine, or heavy oil engine.
An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon, without a theory to explain its behavior and often confused with magnetism. By the end of the 17th century, researchers had developed practical means of generating electricity by friction, but the development of electrostatic machines did not begin in earnest until the 18th century, when they became fundamental instruments in the studies about the new science of electricity.
A porthole, sometimes called bull's-eye window or bull's-eye, is a generally circular window used on the hull of ships to admit light and air. Though the term is of maritime origin, it is also used to describe round windows on armored vehicles, aircraft, automobiles and even spacecraft.
Precursors of film are concepts and devices that have much in common with the later art and techniques of cinema.
R and W Hawthorn Ltd was a locomotive manufacturer in Newcastle upon Tyne, England, from 1817 until 1885.
A friction drive or friction engine is a type of transmission that utilises the static friction of two smooth surfaces to transfer torque between two rotating parts.
