Voltage spike

In electrical engineering, spikes are fast, short duration electrical transients in voltage (voltage spikes), current (current spikes), or transferred energy (energy spikes) in an electrical circuit.

Fast, short duration electrical transients (overvoltages) in the electric potential of a circuit are typically caused by

In the design of critical infrastructure and military hardware, one concern is of pulses produced by nuclear explosions, whose nuclear electromagnetic pulses distribute large energies in frequencies from 1 kHz into the gigahertz range through the atmosphere.

The effect of a voltage spike is to produce a corresponding increase in current (current spike). However some voltage spikes may be created by current sources. Voltage would increase as necessary so that a constant current will flow. Current from a discharging inductor is one example.

Power Surge (ride)

Power Surge is a high-impact thrill ride designed by Italian ride manufacturer Zamperla. The Power Surge was first operated in 1999, and is produced in both trailer-mounted and park versions. Zamperla recommends that riders be 48 inches (122 cm) or taller; however, 52 inches (132 cm) is more common.

Design and operation

Six fixed arms are connected in an asterisk pattern, with two sets of two seats attached at right angles to the arms. The arm assembly is connected to a main arm. Twenty-four riders at a time can be loaded onto the ride. Riders are restrained by an over-the-shoulder harness, with their legs dangling free for excitement.

When this ride is activated, multiple movements occur. The arm assembly rotates, the main arm is raised from the stationay position to an angle of approximately seventy degrees from the horizontal. Once this height is reached, the main arm is capable of rotating, with the combined rotations of both sections causing the seat sets to swing and rotate around the point of attachment. The rotating components can move in both clockwise and anti-clockwise directions, and the different movements can be activated in isolation of each other.

Power!

Power! (known as Critical Mass in Europe) is a computer game developed by Simon Francis in 1985 for the Amstrad CPC, Commodore 64 and ZX Spectrum.

Plot

The player operates a rocket-powered hovercraft whose mission is to destroy an enemy transfer beam that is protected not only by long-distance enemy raiders and mines, but also molecular disorientation that sucks the energy from the player's attack craft.

Gameplay

The player may control the hovercraft in either a normal joystick operational mode or with vectored movement. When the player pushes forward on the joystick, the hovercraft accelerates, and when pulling back on the joystick, speed decreases.

Reception

In 1988, Dragon reviewed Power!, and gave the game 4 out of 5 stars.

PoweredUSB

PoweredUSB, also known as Retail USB, USB PlusPower, and USB +Power, is an addition to the Universal Serial Bus standard that allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter. It is mostly used in point-of-sale equipment, such as receipt printers and barcode readers.

History

PoweredUSB, as a proprietary variant of USB, was developed and proposed by IBM, Berg (now FCI), NCR and Microsoft between 1998 and 1999, with the last revision (0.8g) issued in 2004. The specification is not endorsed by the USB Implementers Forum (USB-IF). IBM, who owns patents to PoweredUSB, charges a licensing fee for its use.

PoweredUSB was licensed by Hewlett-Packard, Cyberdata, Fujitsu, Wincor and others.

Implementation

PoweredUSB uses a more complex connector than standard USB, maintaining the standard USB 1.x/2.0 interface for data communications and adding a second connector for power. Physically, it is essentially two connectors stacked such that the bottom connector accepts a standard USB plug and the top connector takes a power plug.

Power (2014 Telugu film)

Power is a 2014 Telugu action comedy film written and directed by K. S. Ravindra and produced by Rockline Venkatesh under the banner Rockline Entertainments, both marking their debut in Telugu cinema. It features Ravi Teja playing a dual role with Hansika Motwani and Regina Cassandra playing the female lead roles. S. Thaman composed the music while Gautham Raju edited the film. Arthur A. Wilson and Jayanan Vincent handled the film's cinematography. The film revolves around two similar looking people, Baldev Sahay - a corrupt ACP in Kolkata and Tirupathi - a person aspiring to become a police officer in Hyderabad. The home minister of Kolkata recruits Tirupathi to play as Baldev to catch a gangster rescued by Baldev. Rest of the story is all about why Baldev became a corrupt cop and how Tirupathi executed the unfinished mission of Baldev.

Production began on 11 December 2013. The film's talkie part was shot in Hyderabad, Bangalore, Kolkata, Chennai and Bangkok while two songs were shot in Bulgaria marking it the first Telugu film to be shot there. Principal photography ended on 14 August 2014. The film released on 12 September 2014 to positive reviews from critics and was a commercial success.

Surge (soft drink)

Surge (sometimes styled as SURGE) is a citrus flavored soft drink developed by the New Products team at Coca Cola Atlanta in 1996–97. Surge was first produced by The Coca-Cola Company to compete with Pepsi's Mountain Dew during the 1990s. Surge was advertised as having a more "hardcore" edge, much like Mountain Dew's advertising at this time, in an attempt to further take customers away from Pepsi. It was originally launched in Norway as Urge, and was so popular that it was later released in America as Surge. Lagging sales caused production to be ended in 2003 for most markets, and by 2014 Norway was the last country where either Urge or Surge were still sold. However, popular fan bases such as Facebook's "SURGE Movement" led Coca-Cola to re-release the soft drink on September 15, 2014 for the US market via Amazon.com "Prime" in 12-packs of 16 oz. cans. In February 2015, Coca-Cola initiated a test market for the beverage in stores primarily in the Southeastern United States, and concluded in May 2015. Some locations outside of the test region have also been found to sell Surge. Surge was re-released to stores in the Southeast, Northeast, and parts of the Midwest United States in September 2015.
