A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion. It is often a part of a rotating wheel or shaft that strikes a lever at one or more points on its circular path. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer, for example, or an eccentric disc or other shape that produces a smooth reciprocating motion in the follower, which is a lever making contact with the cam. A cam timer is similar, and were widely used for electric machine control before the advent of inexpensive electronics, microcontrollers, integrated circuits, programmable logic controllers and digital control.
In guns, particularly firearms, but not artillery, where a different definition may apply, caliber is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a US "45 caliber" firearm has a barrel diameter of roughly 0.45 inches (11.43mm). Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa.
A warded lock is a type of lock that uses a set of obstructions, or wards, to prevent the lock from opening unless the correct key is inserted. The correct key has notches or slots corresponding to the obstructions in the lock, allowing it to rotate freely inside the lock.
In music, groove is the sense of an effect ("feel") of changing pattern in a propulsive rhythm or sense of "swing". In jazz, it can be felt as a quality of persistently repeated rhythmic units, created by the interaction of the music played by a band's rhythm section. Groove is a significant feature of popular music, and can be found in many genres, including salsa, rock, soul, funk, and fusion.
StepMania is a cross-platform rhythm video game and engine. It was originally developed as a clone of Konami's arcade game series Dance Dance Revolution, and has since evolved into an extensible rhythm game engine capable of supporting a variety of rhythm-based game types. Released under the MIT License, StepMania is open-source free software.
IEC 60309 is a series of international standards from the International Electrotechnical Commission (IEC) for "plugs, socket-outlets and couplers for industrial purposes". They are also referred to as "pin & sleeve" connectors in North America or as "CeeForm" connectors in the entertainment industry. The maximum voltage allowed by the standard is 1000 V DC or AC; the maximum current, 800 A; and the maximum frequency, 500 Hz. The ambient temperature range is −25 °C to 40 °C.
Swaging is a forging process in which the dimensions of an item are altered using dies into which the item is forced. Swaging is usually a cold working process, but also may be hot worked.
Brain coral is a common name given to various corals in the families Mussidae and Merulinidae, so called due to their generally spheroid shape and grooved surface which resembles a brain. Each head of coral is formed by a colony of genetically identical polyps which secrete a hard skeleton of calcium carbonate; this makes them important coral reef builders like other stony corals in the order Scleractinia. Brain corals are found in shallow warm water coral reefs in all the world's oceans. They are part of the phylum Cnidaria, in a class called Anthozoa or "flower animals". The lifespan of the largest brain corals is 900 years. Colonies can grow as large as 1.8 m (6 ft) or more in height.
A car key or an automobile key is a key used to open and/or start an automobile. Modern key designs are usually symmetrical, and some use grooves on both sides, rather than a cut edge, to actuate the lock. It has multiple uses for the automobile with which it was sold. A car key can open the doors, as well as start the ignition, open the glove compartment and also open the trunk (boot) of the car. Some cars come with an additional key known as a valet key that starts the ignition and opens the driver's side door, but prevents the valet from gaining access to valuables that are located in the trunk or the glove box. Some valet keys, particularly those to high-performance vehicles, go so far as to restrict the engine's power output to prevent joyriding. Recently, features such as coded immobilizers have been implemented in newer vehicles. More sophisticated systems make ignition dependent on electronic devices, rather than the mechanical keyswitch. A number of these systems, such as KeeLoq and Megamos Crypto have been demonstrated to be weak and vulnerable to cryptanalytic attacks.
The Chevrolet Trax is one of three small car concepts introduced at the 2007 New York International Auto Show. The Trax showcases a new style of small car from General Motors with a two-tone exterior. The mini car was completely designed by GM Daewoo in South Korea. The small hood houses a 1.0 L gas engine with a top speed of 105 mph (169 km/h).
The Chevrolet Groove is one of three small car concepts introduced on 4 April 2007 at the New York International Auto Show.
A spline is a ridge or tooth on a drive shaft that matches with a groove in a mating piece and transfers torque to it, maintaining the angular correspondence between them.
Charles Reuben Keyes was a pioneering American archaeologist and linguist based in Iowa, known as the founder of modern Iowa archaeology. He is, with Ellison Orr (1857-1951), considered a key person to gaining protection for the Effigy Mounds National Monument, established by Congress in 1949 to protect hundreds of prehistoric earthworks built by indigenous Native American cultures.
The Mountbatten Brailler is an electronic machine used to type braille on braille paper. It uses the traditional "braille typewriter keyboard" of the Perkins Brailler with modern technology, giving it a number of additional features such as word processing, audio feedback and embossing. The machine was pioneered and developed at the United Kingdom's Royal National College for the Blind in Hereford by Ernest Bate.
French Reef is a coral reef located within the Florida Keys National Marine Sanctuary. It lies 11 km southeast of Key Largo, within the Key Largo Existing Management Area, which is immediately to the east of John Pennekamp Coral Reef State Park. French Reef is northeast of Molasses Reef. Part of the reef lies within a Sanctuary Preservation Area (SPA), which is 37 ha in area. A number of caves and arches in a spur and groove formation are included in the SPA.
An Ortman key is a coupling device used to secure two adjacent cylindrical segments of a pressure vessel common in tactical rocket motors. An Ortman key is made of elongated rectangular metal bar stock, such as steel, and is inserted into juxtaposed annular grooves around the circumference of the mating parts. The Ortman key assembly is used in high-pressure applications where packaging, strength and mass are important.
Paul Frank Martinez was an English session musician and songwriter. Born in Leicester, England, Martinez was best known for his work with Robert Plant, Cat Stevens, Jackie Edwards, Dave Edmunds, George Harrison, Maggie Bell, Vasco Rossi, Peter Gabriel, Chicken Shack, and The Adverts, among others.
