NEMA connector

NEMA connectors are power plugs and receptacles used for AC mains electricity in North America and other countries that use the standards set by the US National Electrical Manufacturers Association. NEMA wiring devices are made in current ratings from 15 to 60 amperes (A), with voltage ratings from 125 to 600 volts (V). Different combinations of contact blade widths, shapes, orientation, and dimensions create non-interchangeable connectors that are unique for each combination of voltage, electric current carrying capacity, and grounding system.

NEMA 1 (two-prong, no DC safety ground) and NEMA 5 (three-prong, with safety ground pin) connectors are used for commonplace domestic electrical equipment; the others are for heavy duty or special purposes. NEMA 5-15R is the standard 15 A capacity electric receptacle (outlet) found in the United States. Similar and interchangeable connectors are used in Canada and Mexico.

The dimensional standard for electrical connectors is ANSI/NEMA WD-6 and is available from the NEMA website.

National Electrical Manufacturers Association

The National Electrical Manufacturers Association (NEMA) is the association of electrical equipment and medical imaging manufacturers in the United States. It was founded in 1926 and maintains its headquarters in Rosslyn, Virginia, just outside Washington, D.C. Its approximately 450 member companies manufacture products used in the generation, transmission, distribution, control, and end use of electricity. These products are used in utility, industrial, commercial, institutional, and residential applications. The association’s Medical Imaging & Technology Alliance (MITA) division represents manufacturers of cutting-edge medical diagnostic imaging equipment including MRI, CT, x-ray, and ultrasound products. Global sales of NEMA-scoped products exceed $140 billion. NEMA also has offices in Beijing and Mexico City.

In addition to lobbying activities, NEMA publishes more than 600 standards, application guides, white papers, and technical papers.

NEMA (machine)

In the history of cryptography, the NEMA (NEue MAschine) ("new machine"), also designated the T-D (Tasten-Druecker-Maschine) ("key-stroke machine"), was a 10-wheel rotor machine designed by the Swiss Army during World War II as a replacement for their Enigma machines.

History

The Swiss became aware that their current machine, a commercial Enigma (the Swiss K), had been broken by both Allied and German cryptanalysts.

A new design was begun between 1941 and 1943 by Captain Arthur Alder, a professor of mathematics at the University of Bern. The team which designed the machine also included Professors Hugo Hadwiger and Heinrich Emil Weber.

In the spring of 1944, the first prototype had become available. After some modifications, the design was accepted in March 1945, and production of 640 machines began the following month by Zellweger AG. The first machine entered service in 1947.

NEMA was declassified on 9 July 1992, and machines were offered for sale to the public on 4 May 1994.

Fall (Once Upon a Time)

"Fall" is the ninth episode of the fourth season of the American fantasy drama series Once Upon a Time, which aired on November 30, 2014.

Plot

Opening Sequence

In the forest, snow falls over Elsa and Anna's parents' ship at the bottom of the sea. Gerda's message to her daughters lies on the ocean floor.

In Arendelle and at sea

Anna (Elizabeth Lail) and Kristoff (Scott Michael Foster) are trying to find Elsa when Hans (Tyler Jacob Moore) and his brothers arrive to imprison them for treason. Anna and Kristoff escape and decide to go to the pirate Blackbeard (Charles Mesure), to look for the wishing star which they can use to free Elsa, who is trapped in a magic urn.

They tell Blackbeard that they will pay for the wishing star with his weight in gold, but Hans and his brothers suddenly appear and tell Anna and Kristoff that this a set-up. Hans then says that Arendelle has been frozen for 30 years, which surprises Anna and Kristoff. As they worry about what may have happened to Elsa and what the Snow Queen has done since then, they are put in a trunk, which is then locked and dumped into the sea by Hans and Blackbeard so Hans and his brothers can take over Arendelle.
