Crosfield Electronics
Crosfield Electronics was a British electronics imaging company founded by John Crosfield (1915 - 2012) and Dennis Bent in 1947 to produce process imaging devices for the print industry. The firm was notable for its innovation in colour drum scanning in its ''Scanatron'' (1959) and later ''Magnascan'' (1969) products. The company was acquired by De la Rue in 1974. The firm was eventually taken over by Fujifilm , trading as Fujifilm, or simply Fuji, is a Japanese multinational conglomerate headquartered in Tokyo, Japan, operating in the realms of photography, optics, office and medical electronics, biotechnology, and chemicals.

John Crosfield
John Fothergill Crosfield CBE DSc MA (22 October 1915 in Hampstead, London – 25 March 2012 in Hampstead, London), inventor and entrepreneur, was a pioneer in the application of electronics to all aspects of colour printing and the inventor of the acoustic and subsonic mines during the Second World War. Graduating with a degree in mechanical sciences from Cambridge University in 1936, Crosfield was working on electrical lifts for ASEA in Sweden when war was declared. He joined the Admiralty, where with a team of mathematicians and engineers he was charged with developing sonar, to detect midget submarines, and new types of mines. In 1947, Crosfield founded J F Crosfield Ltd. (later Crosfield Electronics Ltd.) to develop press control equipment, beginning with the Autotron, that enabled magazines to print economically in colour. Following this, the company played a leading role in the introduction of colour scanning in 1958, phototypesetting and later the automated composit ...

Image Scanner
An image scanner—often abbreviated to just scanner—is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop ''flatbed scanner'' where the document is placed on a glass window for scanning. ''Hand-held scanners'', where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications. Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical. Modern scanners typically use a charge-coupled device (CCD) or a contact image sensor (CIS) as the image sensor, whereas ''drum scanners'', developed earlier and still used for the highest possible image quality, use a photomultiplier tube (PMT) as the image sensor. A ''rotary scanner,'' used for high-speed docum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De La Rue
De La Rue plc (, ) is a British company headquartered in Basingstoke, England, that designs and produces banknotes, secure polymer substrate and banknote security features (including security holograms, security threads and security printed products) for central banks and currency issuing authorities.

Electronics Companies Of The United Kingdom
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small elect ...
