Erwin Sick
Erwin Sick (3 November 1909 – 3 December 1988) was a German inventor and entrepreneur who was born in Heilbronn. Life and career Erwin Sick began his professional career in 1924 with an apprenticeship in optometry and then attended the College of Optics and Precision Mechanics in Göttingen. In 1932 he got a job at Siemens & Halske, where he initially worked in the computer lab. From 1934 to 1939 Erwin Sick held various positions at Siemens, Bosch and Askania Werke AG initially as a designer and later as an engineer. There he was involved in development projects on color film, cinema technology, astronomical and physical devices. In 1939 he became head of the Laboratory of Optical Works A&C Steinheil & Söhne, Munich. In 1945 he quit the job and ventured into self-employment. Because he was politically unencumbered, Erwin Sick received his license to "Practice his profession as an engineer" on 26 September 1946 by the American military government. That was the birth of the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Medieval period: Rise of the merchant class Merchants emerged as a social class in medieval Italy. Between 1300 and 1500, modern accounting, the bill of exchange, and limited liability were invented, and thus, the world saw "the first true bankers", who were certainly businesspeople. Around the same time, Europe saw the " emergence of rich merchants." This "rise of the merchant class" came as Europe "needed a middleman" for the first time, and these "burghers" or "bourgeois" were the people who played this role.

People From Heilbronn
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Light Curtain
A light curtain is a safety device that detects when a beam of infrared light has been broken by a person passing through an area. Light curtains, now more commonly known as opto-electronic devices, are used to safeguard personnel in the vicinity of moving machinery with the potential to cause harm such as presses, winders and palletisers. Light curtains can be used as an alternative to mechanical barriers and other forms of traditional machine guarding. By reducing the need for physical guards and barriers, light curtains can increase the maintainability of the equipment they are guarding. The operability and efficiency of machinery can also be improved by the use of light curtains by, for example, allowing easier access for semi-automatic procedures. History The concept was first introduced as a "light barrier" by German inventor Erwin Sick in 1972 when he formally described this device in a patent application as: A year later, he followed up by also applying his patent i ...

Autocollimation
{{more citations needed, date=November 2021 Autocollimation is an optical setup where a collimated beam (of parallel light rays) leaves an optical system and is reflected back into the same system by a plane mirror. It is used for measuring small tilting angles of the mirror, see autocollimator, or for testing the quality of the optical system or of a part of it. Large-aperture optics, however, are tested with a null corrector avoiding the production of a large plane mirror. One special application is to determine the focal length of a diverging lens: a light source is placed at twice the focal length of a converging lens on one side and a screen at the same distance on the other side so that the image of the light source is the sharpest possible. When this is achieved, the screen is replaced with a mirror and the diverging lens is inserted between the converging lens and the mirror at such a distance to the mirror that the light returning through the diverging and converging l ...
