The Hungarian engineer Dénes Mihály patented an image scanning with line deflection, in which each point of an image is scanned ten times per second by a selenium cell. August Karolus (1893–1972) invents the Kerr cell , an almost inertia-free conversion of electrical pulses into light signals.

The timeline of historic inventions is a chronological list of particularly significant technological inventions and their inventors, where known. [ a ] The dates in this article make frequent use of the units mya and kya , which refer to millions and thousands of years ago, respectively.
Graphical timelines provide a visual representation for the timespan of multiple events that have a particular duration, over the course of centuries or millennia. Timelines by year are timelines for one particular year that show the developments for that year within the topical area of that timeline.
Engineering advances in the 1880s, including the invention of the transformer, led to electric utilities starting to adopting alternating current, up until then used primarily in arc lighting systems, as a distribution standard for outdoor and indoor lighting (eventually replacing direct current for such purposes).
Timeline of telescopes, observatories, and observing technology; Timeline of temperature and pressure measurement technology; Timeline of cultivation and domestication in South and West Asia; Timeline of global surveillance disclosures (2013–present) Timeline of online video; Timeline of the introduction of color television in countries and ...
This article details the history of electronics engineering. Chambers Twentieth Century Dictionary (1972) defines electronics as "The science and technology of the conduction of electricity in a vacuum, a gas, or a semiconductor, and devices based thereon".
Originally, the United Engineering Foundation had made a grant to develop an engineering intersociety web platform as a central historical repository. [9] Initially, the work was mainly done at the IEEE History Center. [10] annexed to the Stevens Institute of Technology in Hoboken, NJ. [11]
