Teledyne E2v
Teledyne e2v (previously known as e2v) is a manufacturer with its headquarters in England, that designs, develops and manufactures systems and components in healthcare, life sciences, space, transportation, defence and security and industrial markets. The company was previously known as English Electric Valve Company and for a short time Marconi Applied Technologies. e2v was acquired by US company Teledyne Technologies in March 2017. Company history The company began in the early 1940s as a part of the Marconi group, manufacturing magnetrons for defence Radar systems. The company was first registered as a separate company in Chelmsford, Essex in 1947 under Semyon Aisenstein. Its initial name was the Phoenix Dynamo Co Ltd, though it immediately changed its name to English Electric Valve Company Ltd. In 1959 Bob Coulson established travelling-wave tube and microwave tube sections and they were producing ceramic hydrogen thyratrons as well. By this time EEV was the largest hi-tec ...

Hubble Space Telescope
The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a mirror, and its five main instruments observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. Hubble's orbit outside the distortion of Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most detaile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wide Field Camera 3
The Wide Field Camera 3 (WFC3) is the Hubble Space Telescope's last and most technologically advanced instrument to take images in the visible spectrum. It was installed as a replacement for the Wide Field and Planetary Camera 2 during the first spacewalk of Space Shuttle mission STS-125 (Hubble Space Telescope Servicing Mission 4) on May 14, 2009. WFC3 was still operating. Specifications The instrument is designed to be a versatile camera capable of imaging astronomical targets over a very wide wavelength range and with a large field of view. It is a fourth-generation instrument for Hubble. The instrument has two independent light paths: a UV and optical channel that uses a pair of charge-coupled devices (CCD) to record images from 200 to 1000 nm; and a near infrared detector array that covers the wavelength range from 800 to 1700 nm. The UV/optical channel has two CCDs, each 2048×4096 pixels, while the IR detector is 1024×1024. The focal planes of both channe ...

Charge-coupled Devices
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and professional digital cameras, act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Member Of The Most Excellent Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anode
An anode is an electrode of a polarized electrical device through which conventional current enters the device. This contrasts with a cathode, an electrode of the device through which conventional current leaves the device. A common mnemonic is ACID, for "anode current into device". The direction of conventional current (the flow of positive charges) in a circuit is opposite to the direction of electron flow, so (negatively charged) electrons flow out the anode of a galvanic cell, into an outside or external circuit connected to the cell. For example, the end of a household battery marked with a "-" (minus) is the anode. In both a galvanic cell and an electrolytic cell, the anode is the electrode at which the oxidation reaction occurs. In a galvanic cell the anode is the wire or plate having excess negative charge as a result of the oxidation reaction. In an electrolytic cell, the anode is the wire or plate upon which excess positive charge is imposed. As a result of this, anion ...

Cathode
A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic ''CCD'' for ''Cathode Current Departs''. A conventional current describes the direction in which positive charges move. Electrons have a negative electrical charge, so the movement of electrons is opposite to that of the conventional current flow. Consequently, the mnemonic ''cathode current departs'' also means that electrons flow ''into'' the device's cathode from the external circuit. For example, the end of a household battery marked with a + (plus) is the cathode. The electrode through which conventional current flows the other way, into the device, is termed an anode. Charge flow Conventional current flows from cathode to anode outside of the cell or device (with electrons moving in the opposite direction), regardless of the cell or device type and operating mode. Cathode polarity with respect to the anode can be positive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elmsford, New York
Elmsford is a village in Westchester County, New York, United States. It is part of the New York metropolitan area. Roughly one mile square, the village is fully contained within the borders of the town of Greenburgh. As of the 2010 census, the population of Elmsford was 4,664. History Elmsford was largely farmland throughout its early history. The construction of railroads in the late 19th century brought new prominence to the area, and in 1910 it was incorporated as a village. The area was known from colonial times as "Storm's Bridge" and later, "Hall's Corners", names derived from the principal landowners of the times. In 1870, the growing village was officially renamed "Elmsford" in honor of a local landmark, a giant elm tree (since deceased). The names Elmsford and Storm's Bridge are reminders of the nearby Saw Mill River, which once had significant tributaries flowing through the village. A longstanding legend holds that Elmsford is the birthplace of the term "cocktail" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
