Shuffling Machine
A shuffling machine is a machine for randomly shuffling packs of playing cards. Because standard shuffling techniques are seen as weak, and in order to avoid "inside jobs" where employees collaborate with gamblers by performing inadequate shuffles, many casinos employ automatic shuffling machines to shuffle the cards before dealing. These machines are also used to reduce repetitive motion stress injuries to a dealer. Shuffling machines have to be carefully designed, as they can generate biased shuffles otherwise: the most recent shuffling machines are computer-controlled. The randomness or otherwise of cards produced from automatic shuffling machines is the subject of considerable interest to both gamblers and casinos. Shuffling machines come in two main varieties: continuous shuffling machines (CSMs), which shuffle one or more packs continuously, and batch shufflers or automatic shuffling machines (ASMs), which shuffle an entire single pack in a single operation.

Hot Cathode
In vacuum tubes and gas-filled tubes, a hot cathode or thermionic cathode is a cathode electrode which is heated to make it emit electrons due to thermionic emission. This is in contrast to a cold cathode, which does not have a heating element. The heating element is usually an electrical filament heated by a separate electric current passing through it. Hot cathodes typically achieve much higher power density than cold cathodes, emitting significantly more electrons from the same surface area. Cold cathodes rely on field electron emission or secondary electron emission from positive ion bombardment, and do not require heating. There are two types of hot cathode. In a ''directly heated cathode'', the filament is the cathode and emits the electrons. In an ''indirectly heated cathode'', the filament or ''heater'' heats a separate metal cathode electrode which emits the electrons. From the 1920s to the 1960s, a wide variety of electronic devices used hot-cathode vacuum tub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SHFL Entertainment
SHFL entertainment, Inc. (previously named Shuffle Master) was a manufacturer of shuffling machines, table games, slot machines, and other casino products, based in Paradise, Nevada. Founded in 1983, it was acquired by Bally Technologies in 2013. Bally was itself acquired the following year by Scientific Games, now Light & Wonder, which continues to use the Shuffle Master name as one of its core brands. The company designed Deck Mate, one of the primary card shuffling devices used in casinos. The company's table game products included Let It Ride, Three Card Poker, Blackjack Switch, and Casino War. History Shuffle Master was formed by John Breeding, a former truck driver, in 1983. Inspired by a newspaper article about card counting in blackjack, he borrowed $30,000 to develop a mechanical shuffler that would allow every hand to be dealt from a fresh deck, nullifying the advantage of card counting, without losing valuable playing time. The device finally came to market in early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MindPlay
MindPlay was a technology designed to monitor blackjack players' actions while playing in a casino, first released in 2003 and discontinued in 2007. Monitoring a person's play traditionally is done visually, by the dealer, floorperson, pitboss, and the '' eye in the sky'' (video surveillance). If one of these observers notices something unusual in a person's play, they will do what they can to either # determine if the person is a cheat or a card counter, or # change the game to turn the odds back in favor of the casino, through more frequent card-shuffling or other methods, or # bar a player they think is a card counter, even though the practice is legal. Operation MindPlay utilizes a specially-designed blackjack tabletop that incorporates many features to monitor players' actions: * Specially encoded playing cards, using invisible ink and barcodes; see card marking Card marking is the process of altering playing cards in a method only apparent to marker or conspirator, suc ...

Mahjong
Mahjong or mah-jongg (English pronunciation: ) is a tile-based game that was developed in the 19th century in China and has spread throughout the world since the early 20th century. It is commonly played by four players (with some three-player variations found in parts of China, Japan, South Korea and Southeast Asia). The game and its regional variants are widely played throughout East and Southeast Asia and have also become popular in Western countries. The game has also been adapted into a widespread online entertainment. Similar to the Western card game rummy, Mahjong is a game of skill, strategy, and luck. To distinguish it from mahjong solitaire, it is sometimes referred to as mahjong rummy. The game is played with a set of 144 tiles based on Chinese characters and symbols, although many regional variations may omit some tiles or add unique ones. In most variations, each player begins by receiving 13 tiles. In turn, players draw and discard tiles until they complete ...

Hammond Electric Bridge Table
The Hammond Electric Bridge Table was an electromechanical automatic card shuffling machine that dealt playing cards at random to four bridge players. The mechanism was built into a card table. The main concept of the machine was as a labor saving aid for bridge players in dealing out the hands. The invention was an offspring from the Hammond Clock Company as an additional product. It was a popular device when first introduced at the pre-Christmas season of 1932. That was short lived, however, and production lasted only a couple of years. Development The device has its origins with the Hammond Clock Company which was formed by Laurens Hammond in 1928 in Chicago, Illinois. By 1932, over one hundred clock companies had gone out of business due to the Great Depression but Hammond was determined to remain solvent and created new products for the company to sell. One such product was an automatic card dealer. Hammond was a bridge player and a mechanical engineer and he put th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lottery Machine
A lottery is a form of gambling that involves the drawing of numbers at random for a prize. Some governments outlaw lotteries, while others endorse it to the extent of organizing a national or state lottery. It is common to find some degree of regulation of lottery by governments. The most common regulation is prohibition of sale to minors, and vendors must be licensed to sell lottery tickets. Although lotteries were common in the United States and some other countries during the 19th century, by the beginning of the 20th century, most forms of gambling, including lotteries and sweepstakes, were illegal in the U.S. and most of Europe as well as many other countries. This remained so until well after World War II. In the 1960s, casinos and lotteries began to re-appear throughout the world as a means for governments to raise revenue without raising taxes. Lotteries come in many formats. For example, the prize can be a fixed amount of cash or goods. In this format, there is risk t ...

Photosensor
Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation. There is a wide variety of photodetectors which may be classified by mechanism of detection, such as photoelectric or photochemical effects, or by various performance metrics, such as spectral response. Semiconductor-based photodetectors typically photo detector have a p–n junction that converts light photons into current. The absorbed photons make electron–hole pairs in the depletion region. Photodiodes and photo transistors are a few examples of photo detectors. Solar cells convert some of the light energy absorbed into electrical energy. Types Photodetectors may be classified by their mechanism for detection: * Photoemission or photoelectric effect: Photons cause electrons to transition from the conduction band of a material to free electrons in a vacuum or gas. * Thermal: Photons cause electrons to transition to mid-gap states then decay back to lower bands, inducing ph ...

AND Gate
The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic AND gate behaves according to the truth table. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If not all inputs to the AND gate are HIGH, LOW output results. The function can be extended to any number of inputs. Symbols There are three symbols for AND gates: the American (ANSI or 'military') symbol and the IEC ('European' or 'rectangular') symbol, as well as the deprecated DIN symbol. Additional inputs can be added as needed. For more information see Logic gate symbols article. It can also be denoted as symbol "^" or "&". The AND gate with inputs ''A'' and ''B'' and output ''C'' implements the logical expression C = A \cdot B. This expression also may be denoted as C=A \wedge B or C=A \And B. Implementations An AND gate can be designed using only N-channel (pictured) or P-channel MOSFETs, but is usually implemented with both (CMOS). ...

Multivibrator
A multivibrator is an electronic circuit used to implement a variety of simple two-state devices such as relaxation oscillators, timers, and flip-flops. The first multivibrator circuit, the astable multivibrator oscillator, was invented by Henri Abraham and Eugene Bloch during World War I. It consisted of two vacuum tube amplifiers cross-coupled by a resistor-capacitor network. They called their circuit a "multivibrator" because its output waveform was rich in harmonics. A variety of active devices can be used to implement multivibrators that produce similar harmonic-rich wave forms; these include transistors, neon lamps, tunnel diodes and others. Although cross-coupled devices are a common form, single-element multivibrator oscillators are also common. The three types of multivibrator circuits are: * Astable multivibrator, in which the circuit is not stable in either state —it continually switches from one state to the other. It functions as a relaxation oscillator. * Mon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shuffling
Shuffling is a procedure used to randomize a deck of playing cards to provide an element of chance in card games. Shuffling is often followed by a cut, to help ensure that the shuffler has not manipulated the outcome. __TOC__ Techniques Overhand One of the easiest shuffles to accomplish after a little practice is the overhand shuffle. Johan Jonasson wrote, "The overhand shuffle... is the shuffling technique where you gradually transfer the deck from, say, your right hand to your left hand by sliding off small packets from the top of the deck with your thumb." In detail as normally performed, with the pack initially held in the left hand (say), most of the cards are grasped as a group from the bottom of the pack between the thumb and fingers of the right hand and lifted clear of the small group that remains in the left hand. Small packets are then released from the right hand a packet at a time so that they drop on the top of the pack accumulating in the left hand. The proces ...
