Lock And Key
A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token or coin), by supplying secret information (such as a number or letter permutation or password), by a combination thereof, or it may only be able to be opened from one side, such as a door chain. A key is a device that is used to operate a lock (to lock or unlock it). A typical key is a small piece of metal consisting of two parts: the '' bit'' or ''blade'', which slides into the keyway of the lock and distinguishes between different keys, and the ''bow'', which is left protruding so that torque can be applied by the user. In its simplest implementation, a key operates one lock or set of locks that are keyed alike, a lock/key system where each similarly keyed lock requires the same, unique key. The key serves as a security token for access to the locked area; locks are meant to only allow persons having the correct key to ...

Lock (rugby League)
A rugby league team consists of thirteen players on the field, with 4 substitutes on the bench. Each of the thirteen players is assigned a position, normally with a standardised number, which reflects their role in attack and defence, although players can take up any position at any time. Players are divided into two general types, forwards and backs. Forwards are generally chosen for their size and strength. They are expected to run with the ball, to attack, and to make tackles. Forwards are required to improve the team's field position thus creating space and time for the backs. Backs are usually smaller and faster, though a big, fast player can be of advantage in the backs. Their roles require speed and ball-playing skills, rather than just strength, to take advantage of the field position gained by the forwards. Typically forwards tend to operate in the centre of the field, while backs operate nearer to the touch-lines, where more space can usually be found. Names and numberi ...

-lock
The suffix ''-lock'' in Modern English survives only in '' wedlock'' and '' bridelock''. It descends from Old English ''-lác'' which was more productive, carrying a meaning of "action or proceeding, state of being, practice, ritual". As a noun, Old English ''lác'' means "play, sport", deriving from an earlier meaning of "sacrificial ritual or hymn" (Proto-Germanic ''*laikaz''). A putative term for a "hymn to the gods" (''* ansu-laikaz'') in early Germanic paganism is attested only as a personal name, Oslac. Suffix The Old English nouns in ''-lác'' include ''brýdlác'' "nuptials" (from the now obsolete ''bridelock''), ''beadolác'', ''feohtlác'' and ''heaðolác'' "warfare", ''hǽmedlác'' and ''wiflác'' "sexual intercourse", ''réaflác'' "robbery", ''wítelác'' "punishment", ''wróhtlác'' "calumny" besides the ''wedlác'' "pledge-giving", also "nuptials" ancestral to ''wedlock''. A few compounds appear only in Middle English, thus ''dweomerlak'' "occult practice, magic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dreadlocks
Dreadlocks, also known as locs or dreads, are rope-like strands of hair formed by locking or braiding hair. Origins Some of the earliest depictions of dreadlocks date back as far as 1600–1500 BCE in the Minoan Civilization, one of Europe's earliest civilizations, centred in Crete (now part of Greece). Frescoes discovered on the Aegean island of Thera (modern Santorini, Greece) depict individuals with long braided hair or long dreadlocks. In ancient Egypt, examples of Egyptians wearing locked hairstyles and wigs have appeared on bas-reliefs, statuary and other artifacts. Mummified remains of Egyptians with locked wigs have also been recovered from archaeological sites. During the Bronze and Iron Ages, many peoples in the Near East, Anatolia, Caucasus, East Mediterranean and North Africa such as the Sumerians, Elamites and Ancient Egyptians were depicted in art with braided or plaited hair and beards. However, braids are not dreadlocks, and it is not always possib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock Of Hair
A lock of hair is a piece or pieces of hair that has been cut from, or remains singly on, a human head, most commonly bunched or tied together in some way. A standard dictionary definition defines a lock as a tress, curl, or ringlet of hair. Symbolic value Locks of hair carry symbolic value and have been utilized throughout history in various religious, superstitious, and sentimental roles. * A traditional belief maintains that owning a lock of hair from another's head gives one power over that individual, in the same manner that owning a piece of clothing or image of an individual grants the owner such powers. * Historically, giving a lock of one's hair to someone has been considered a sign of love and devotion, especially before an impending separation. It is still a popular trope in fiction, particularly the romance genre. * During antiquity, Roman girls who were about to be married offered locks of hair to Jove (Jupiter) in his forest god aspect, Virbius (Virbio). * An ...

Rope Lock
In a theater fly system, a rope lock is a device used to prevent a rope, and the line set it controls, from moving. A rope lock is controlled by a steel handle that engages the lock when vertical and releases it when horizontal. The handle is typically red powder coated or covered by a red rubber grip. A steel, oval-shaped safety ring encircles both the rope and the handle to ensure that the lock cannot be accidentally released. Rope locks are mounted to a locking rail, which provides structural support and holds them at a convenient level for the stage crew. Locking mechanism Two metal cams, one stationary and one movable, are used to immobilize the rope. The position of the movable cam is controlled by the locking handle. When the handle is raised, the movable cam is pressed towards the stationary cam so as to grip the rope by compressing it between the cams. Conversely, the lock is released by lowering the handle, thus retracting the movable cam away from the stationary cam an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fermentation Lock
A fermentation lock or airlock is a device used in beer brewing and wine making that allows carbon dioxide released during fermentation to escape the fermenter, while not allowing air to enter the fermenter, thus avoiding oxidation. There are two main designs for the fermentation lock. These designs work when half filled with water. When the pressure of the gas inside the fermentation vessel exceeds the prevailing atmospheric pressure the gas will push its way through the water as individual bubbles into the outside air. A sanitizing solution, sulphur dioxide or alcohol is sometimes placed in the fermentation lock to prevent contamination of the beverage in case the water is inadvertently drawn into the fermenter. This device may take the form of a tube connected to the headspace of the fermenting vessel into a tub of sanitized liquid or a simpler device mounted directly on top of the fermentation vessel. Currently, a popular fermentation lock that mounts on top of the ferm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock (weapons Guidance)
A Constantly Computed Impact Point (CCIP) is a calculation provided by a weapon's sighting system. It is a predicted point of impact found from the launch platform's movement, the target's movement, gravity, projectile launch velocity, projectile drag, and other factors that can be entered. It is usually displayed on the Head Up Display (HUD). The HUD crosshairs will move around dependent on where the computer predicts the selected rocket, bullet or bomb will hit. Normally a radar lock is necessary, but when strafing or bombing a ground target (A/G mode; A/A mode will simply put the hairs in the centre of the HUD), the crosshairs will move along the ground. This system is normally used in aircraft, other large vehicles, or large static weapons, but it is in principle possible for such a system to be miniaturized for a man-portable firearm or Unmanned Combat Aerial Vehicle (UCAV). The Continually Computed Release Point (CCRP) inverts the principle of CCIP. A desired ''impa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock (firearm)
The lock of a firearm is the mechanism used to initiate firing. It is a historical term, in that it generally refers to such mechanisms used in muzzle-loading and early breech-loading firearms. Side-lock refers to the type of construction, in which the individual components of the mechanism are mounted either side of a single plate. The assembly is then mounted to the stock on the side of the firearm. In modern firearm designs, the mechanism to initiate firing is generally constructed within the frame or receiver of the firearm and is referred to as the firing or trigger mechanism. Hand cannon Hand cannon, the earliest of firearms, had arrived in Europe by 1338. These cannons were loaded from the muzzle. The propellent charge is lit through a touch hole. A small priming charge over the touch hole is ignited with a lit piece of slow match or similar. These hand cannons were ungainly: the difficulty being in holding and aiming the weapon while manipulating the slow bur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIM Lock
SIM lock, simlock, network lock, carrier lock or (master) subsidy lock is a technical restriction built into GSM and CDMA mobile phones by mobile phone manufacturers for use by service providers to restrict the use of these phones to specific countries and/or networks. This is in contrast to a phone (retrospectively called SIM-free or unlocked) that does not impose any SIM restrictions. Generally phones can be locked to accept only SIM cards with certain International Mobile Subscriber Identities (IMSIs); IMSIs may be restricted by: * Mobile country code (MCC; e.g., will only work with SIM issued in one country) * Mobile network code (MNC; e.g., AT&T Mobility, T-Mobile, Vodafone, Bell Mobility etc.) * Mobile subscriber identification number (MSIN; i.e., only one SIM can be used with the phone) Additionally, some phones, especially Nokia phones, are locked by group IDs (GIDs), restricting them to a single Mobile virtual network operator (MVNO) of a certain operator. Most mob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File Locking
File locking is a mechanism that restricts access to a computer file, or to a region of a file, by allowing only one user or process to modify or delete it at a specific time and to prevent reading of the file while it's being modified or deleted. Systems implement locking to prevent the classic ''interceding update'' scenario, which is a typical example of a race condition, by enforcing the serialization of update processes to any given file. The following example illustrates the interceding update problem: # Process A reads a customer record from a file containing account information, including the customer's account balance and phone number. # Process B now reads the same record from the same file, so it has its own copy. # Process A changes the account balance in its copy of the customer record and writes the record back to the file. # Process B, which still has the original ''stale'' value for the account balance in its copy of the customer record, updates the account bala ...

Lock (database)
Record locking is the technique of preventing simultaneous access to data in a database, to prevent inconsistent results. The classic example is demonstrated by two bank clerks attempting to update the same bank account for two different transactions. Clerks 1 and 2 both retrieve (i.e., copy) the account's record. Clerk 1 applies and saves a transaction. Clerk 2 applies a different transaction to his saved copy, and saves the result, based on the original record and his changes, overwriting the transaction entered by clerk 1. The record no longer reflects the first transaction, as if it had never taken place. A simple way to prevent this is to lock the file whenever a record is being modified by any user, so that no other user can save data. This prevents records from being overwritten incorrectly, but allows only one record to be processed at a time, locking out other users who need to edit records at the same time. To allow several users to edit a database table at the same ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
