The IBM 9020 was an IBM System/360 computer adapted into a multiprocessor system for use by the U.S. FAA for Air Traffic Control. [1] Systems were installed in the FAA's 20 en route Air Route Traffic Control Centers (ARTCCs), beginning in the late 1960s. [2]: 6 The U.K. CAA also installed a system in its London centre. [3]
Electric power transmission through interconnectors using high-voltage direct-current (HVDC) involves usually two converter stations and a transmission line. Generally overhead lines are used, but an important class of HVDC projects use submarine power cables.

Railroad signal power supply transformer (CP-SLOPE interlocking) in west of Altoona with a warning label indicating that it contains PCBs.. Distribution transformers are normally located at a service drop, where wires run from a utility pole or underground power lines to a customer's premises.
Convergent Technologies, Inc., was an American computer company formed by a small group of people who left Intel Corporation and Xerox PARC in 1979. [2] Among the founders were CEO Allen Michels, VP Engineering Bob Garrow, head of marketing Kal Hubler, and operating system architect Ben Wegbreit.
The Kintetsu 9020 series (近鉄9020系) is an electric multiple unit (EMU) commuter train type operated by the private railway operator Kintetsu Railway since 2000. [1] In 2001, it was awarded the Laurel Prize , presented annually by the Japan Railfan Club.
(It is common for dirty insulators to arc at the highest point of the voltage, and thus generate a wide-band burst of noise.) To avoid other interference, receivers can improve their signal-to-noise ratio by measuring the power of only the 1 tones, only the 0 tones or the differential power of both. Different districts use different tone pairs ...
About 840 million people (mostly in Africa), which is ca. 11% of the World's population, had no access to grid electricity in 2017, down from 1.2 billion in 2010. [ 2 ] Electrical grids can be prone to malicious intrusion or attack; thus, there is a need for electric grid security .
