After spending several years as assistant editor of Practical Wireless and Instrument Practice, Sinclair founded Sinclair Radionics in 1961, where he produced the first slim-line electronic pocket calculator in 1972 ( the Sinclair Executive ).

During the 1980s, the cassette's popularity grew further as a result of portable pocket recorders and high-fidelity (" hi-fi ") players, such as Sony's Walkman ( 1979 ), which used a body not much larger than the cassette tape itself, with mechanical keys on one side, or electronic buttons or display on the face.

This allowed Sinclair to adapt the relatively low-cost processor and produce an ' electronic slide rule ' that fitted easily in a shirt pocket, at a price that even impecunious students could afford.

While remarking that he doesn't believe there are ghosts in 1408, Olin insists there is " something " that resides inside, something that causes terrible things to happen to people who stay within its walls for anything but the briefest periods of time, something that affects various electronic devices, causing digital wristwatches, pocket calculators, and cell phones to stop functioning or to operate unpredictably.

An electronic calculator is a small, portable, often inexpensive electronic device used to perform both basic and complex operations of arithmetic.

The first solid state electronic calculator was created in the 1960s, building on the extensive history of tools such as the abacus, developed around 2000 BC ; and the mechanical calculator, developed in the 17th century.

In general, a basic electronic calculator consists of the following components:

The Casio CM-602 Mini electronic calculator provided basic functions in the 1970s

The first truly pocket-sized electronic calculator was the Busicom LE-120A " HANDY ", which was marketed early in 1971.

Made in Japan, this was also the first calculator to use an LED display, the first hand-held calculator to use a single integrated circuit ( then proclaimed as a " calculator on a chip "), the Mostek MK6010, and the first electronic calculator to run off replaceable batteries.

Through the 1970s the hand-held electronic calculator underwent rapid development.

While with the Naval Ordnance Laboratory he developed an arithmetic element for an electronic digital calculator that he called an " electronic brain.

The use of slide rules continued to grow through the 1950s and 1960s even as digital computing devices were being gradually introduced ; but around 1974 the electronic scientific calculator made it largely obsolete and most suppliers left the business.

The Toshiba " Toscal " BC-1411 electronic calculator, which was introduced in November 1966, used a form of dynamic RAM built from discrete components.

Simon included many applications including an address book, calendar, appointment scheduler, calculator, world time clock, games, electronic note pad, handwritten annotations and standard and predictive touchscreen keyboards.

Wang began making desktop electronic calculators with digital displays, including a centralised calculator with remote terminals for group use.

The prototype ANITA electronic calculator of 1958, with some of the covers removed, on display in the Science Museum ( London ) | Science Museum, London.

The cheapest electronic computer then cost approximately £ 50, 000 ( GBP, about US $ 140, 000 ), but to be competitive with mechanical calculators the target selling price of the electronic calculator was in the range £ 350 to £ 400 ( US $ 980 to 1120 ).

Mr. Devey will be responsible for the commercial expansion of VecTrol's line of electronic and electrical power control components as furnished to end equipment manufacturers, working closely with Walter J. Brown, President and Director of Engineering of the recently acquired Sprague subsidiary.

Mr. Brown will at the same time undertake expansion of VecTrol's custom design program for electronic control users with a greatly increased engineering staff.

Commonly used electronic devices which are found in practically every hospital are closed-circuit TV and audio systems for internal paging and instruction, along with radiation counters, timers, and similar devices.

The preceding methods allow efficient use of index words and electronic switches during a sectionalized or multi-phase program, particularly when used in conjunction with the LITORIGIN statement.

I waited until the parking attendant was busy with a customer, then slipped around the back of the car with license number JYM 114, attached the electronic bug to the rear bumper and walked out.

The contract with Ray Field, who has been converting the agencies electronic data processing program to magnetic tape, would renew his present salary of $8 an hour up to a maximum of 200 hours a month.

However, the idea that electrons might revolve around a compact nucleus with definite angular momentum was convincingly argued at least 19 years earlier by Niels Bohr, and the Japanese physicist Hantaro Nagaoka published an orbit-based hypothesis for electronic behavior as early as 1904.

The arithmetic logic functions were fully electronic, implemented with vacuum tubes.

The control logic functions, which only needed to operate once per drum rotation and therefore did not require electronic speed, were electromechanical, implemented with relays.

Flicker noise is electronic noise with a 1 / ƒ frequency spectrum ; as f increases, the noise decreases.

The group recorded lead singer Matt Thiessen making drum noises and played them with electronic drums to make the song.

Running an electronic analog computer, assuming a satisfactory setup, started with the computer held with some variables fixed at their initial values.

The Lynx holds the distinction of being the world's first handheld electronic game with a color LCD.

The Lynx was the second handheld game with the Atari name to actually be produced, the first was Atari Inc .' s handheld electronic game Touch Me.

Nin appeared in the Kenneth Anger film Inauguration of the Pleasure Dome ( 1954 ) as Astarte ; in the Maya Deren film Ritual in Transfigured Time ( 1946 ); and in Bells of Atlantis ( 1952 ), a film directed by Guiler under the name " Ian Hugo " with a soundtrack of electronic music by Louis and Bebe Barron.
