Crowbar is an American sludge metal band from New Orleans, Louisiana, characterized by their extremely slow, low-keyed, heavy and brooding songs that also contain fast hardcore punk passages. Crowbar is considered to be one of the most influential metal bands to come out of the New Orleans metal scene. Their slow, heavy, and brooding style of metal is known to be influential in the sludge metal, doom metal, and stoner metal genres.
Christopher "Chris" Ford (born March 4, 1974) is an American professional wrestler. Not to be confused with Akeel "The Crowbar" Kazmi a British character, he is best known for his tenure in World Championship Wrestling under the ring name Crowbar, where he was a one time Hardcore Champion, a one time World Tag Team Champion with David Flair and a one time Cruiserweight Champion, which he held jointly with Daffney. He is also known for his stints in the World Wrestling Federation, Extreme Championship Wrestling and Total Nonstop Action Wrestling. He currently performs on the independent circuit either as Crowbar or Devon Storm. Along with Terry Funk, Jerry Lynn, Stevie Richards, and Raven he is one of the only wrestlers to have wrestled matches in WWE, WCW, ECW, TNA and ROH.

A crowbar, (also called a wrecking bar, pry bar or prybar, pinch-bar or occasionally a prise bar or prisebar, and more informally or known to Non-American nations such as Britain and Australia as a jimmy (also called jimmy bar or jemmy) or PikiPiki, gooseneck or pig foot is a tool consisting of a metal bar with a single curved end and flattened points, often with a small fissure on one or both ends for removing nails. In Britain, Ireland, New Zealand and Australia, due to the influence of American media "crowbar" may occasionally be used loosely for this tool, but it is still mainly used to mean a larger straighter tool, its original English meaning (see digging bar). The term jemmy or jimmy most often refers to the tool when used for burglary.
It is used as a lever either to force apart two objects or to remove nails. Crowbars are commonly used to open nailed wooden crates, remove nails, or pry apart boards. Crowbars can be used as any of the three lever classes but the curved end is usually used as a first-class lever, and the flat end as a second class lever. In mining, crowbars are used to break and remove rock, but not as much in modern mining.
Crowbar was a Canadian rock band based in Hamilton, Ontario, best known for their 1971 hit "Oh, What a Feeling".
Crowbar is a fictional supervillain in the DC Universe. He first appeared in Justice League of America #233 (December 1984).
Crowbar is the second studio album by New Orleans sludge metal band Crowbar, released on October 12, 1993. The album sold 100,000 copies on the now defunct independent label Pavement Music. The singles "All I Had (I Gave)" and "Existence Is Punishment" were played on MTV and received international attention. Crowbar was produced by Phil Anselmo, a childhood friend of Crowbar's founder Kirk Windstein and the singer of Pantera, and recorded in New Orleans in 1992.
A crowbar circuit is an electrical circuit used to prevent an overvoltage condition of a power supply unit from damaging the circuits attached to the power supply. It operates by putting a short circuit or low resistance path across the voltage output (V), much as if one were to drop a crowbar across the output terminals of the power supply. Crowbar circuits are frequently implemented using a thyristor, TRIAC, trisil or thyratron as the shorting device. Once triggered, they depend on the current-limiting circuitry of the power supply or, if that fails, the blowing of the line fuse or tripping the circuit breaker.
An example crowbar circuit is shown to the right. This particular circuit uses an LM431 adjustable zener regulator to control the gate of the TRIAC. The resistor divider of R and R provide the reference voltage for the LM431. The divider is set so that during normal operating conditions, the voltage across R is slightly lower than V of the LM431. Since this voltage is below the minimum reference voltage of the LM431, it remains off and very little current is conducted through the zener and cathode resistor. If the cathode resistor is sized accordingly, very little voltage will be dropped across it and the TRIAC gate terminal will be essentially at the same potential as MT1, keeping the TRIAC off. If the supply voltage increases, the voltage across R will exceed V and the zener will begin to regulate voltage, drawing more current through it. The voltage at the gate terminal will be pulled down to V (the zener voltage), exceeding the gate trigger voltage of the TRIAC and latching it on.
A crowbar circuit is distinct from a clamp in that, once triggered, it pulls the voltage below the trigger level, usually close to ground. A clamp prevents the voltage from exceeding a preset level. Thus, a crowbar will not automatically return to normal operation when the overvoltage condition is removed; power must be removed entirely to stop its conduction.
An active crowbar is a crowbar that can remove the short circuit when the transient is over thus allowing the device to resume normal operation. Active crowbars use a transistor, gate turn off (GTO) thyristor or forced commutated thyristor instead of a thyristor to short the circuit. Active crowbars are commonly used to protect the frequency converter in the rotor circuit of doubly fed generators against high voltage and current transients caused by the voltage dips in the power network. Thus the generator can ride through the fault and quickly continue the operation even during the voltage dip.
The advantage of a crowbar over a clamp is that the low holding voltage of the crowbar lets it carry higher fault current without dissipating much power (which could otherwise cause overheating). Also, a crowbar is more likely than a clamp to deactivate a device (by blowing a fuse or tripping a breaker), bringing attention to the faulty equipment.
The term is also used as a verb to describe the act of short-circuiting the output of a power supply, or the malfunction of a CMOS circuit -- the PMOS half of a pair lingering in a near on-state when only its corresponding NMOS is supposed to be on (or the NMOS when the PMOS is supposed to be on) -- resulting in a near short-circuit current between supply rails.
The Crowbar is a type of cocktail made with only Crown Royal whiskey and lemon lime soda. The name refers to the construction workers in Canada that would order these drinks after a long day of hard labor building railroad tracks in the 1940s. It was said to ease the pain after ten hours of extremely demanding physical labor laying down railroad ties.
The standard for Crowbars has been recently relaxed to include any kind of whiskey, not just Crown Royal. There is no requirement for which kind of lemon lime soda is used.
