Bladeless Fan
file:IFA 2010 Internationale Funkausstellung Berlin 109.JPG, The Dyson Air Multiplier at the IFA Berlin trade show in 2010 A bladeless fan, also known as an Air multiplier fan, is a Fan (machine), fan that blows air from a ring or oval opening with no external blades. Its wiktionary:vane#English, vanes are hidden in its pedestal and direct the collected airflow through a toroid, blowing a thin high-velocity smooth airflow from a continuous slot across the surface of the tube or toroid. The concept was created by Toshiba in 1981 and was later popularized by industrial designer James Dyson, who used the technique in a consumer fan introduced in 2009, calling it the Air Multiplier. It was included in Time's 50 Best Inventions of 2009 list. The principle has been in use for a long time as an ejector or injector. History The first concept was created by Toshiba in 1981.

Fan (machine)
A fan is a powered machine used to create a flow of air. A fan consists of a rotating arrangement of vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an '' impeller'', ''rotor'', or ''runner''. Usually, it is contained within some form of housing, or case. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors, handcranks, and internal combustion engines. Mechanically, a fan can be any revolving vane, or vanes used for producing currents of air. Fans produce air flows with high volume and low pressure (although higher than ambient pressure), as opposed to compressors which produce high pressures at a comparatively low volume. A fan blade will often rotate when exposed to an air-fluid stream, and devices that take advantage of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Toroid
In mathematics, a toroid is a surface of revolution with a hole in the middle. The axis of revolution passes through the hole and so does not intersect the surface. For example, when a rectangle is rotated around an axis parallel to one of its edges, then a hollow rectangle-section ring is produced. If the revolved figure is a circle, then the object is called a torus. The term ''toroid'' is also used to describe a toroidal polyhedron. In this context a toroid need not be circular and may have any number of holes. A ''g''-holed ''toroid'' can be seen as approximating the surface of a torus having a topological genus, ''g'', of 1 or greater. The Euler characteristic χ of a ''g'' holed toroid is 2(1-''g'').Stewart, B.; "Adventures Among the Toroids:A Study of Orientable Polyhedra with Regular Faces", 2nd Edition, Stewart (1980). The torus is an example of a toroid, which is the surface of a doughnut. Doughnuts are an example of a solid torus created by rotating a disk, and s ...

Toshiba
, commonly known as Toshiba and stylized as TOSHIBA, is a Japanese multinational conglomerate corporation headquartered in Minato, Tokyo, Japan. Its diversified products and services include power, industrial and social infrastructure systems, elevators and escalators, electronic components, semiconductors, hard disk drives (HDD), printers, batteries, lighting, as well as IT solutions such as quantum cryptography which has been in development at Cambridge Research Laboratory, Toshiba Europe, located in the United Kingdom, now being commercialised. It was one of the biggest manufacturers of personal computers, consumer electronics, home appliances, and medical equipment. As a semiconductor company and the inventor of flash memory, Toshiba had been one of the top 10 in the chip industry until its flash memory unit was spun off as Toshiba Memory, later Kioxia, in the late 2010s. The Toshiba name is derived from its former name, Tokyo Shibaura Denki K.K. (Tokyo Shibaura Electri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Dyson
Sir James Dyson (born 2 May 1947) is a British inventor, industrial designer, farmer, and billionaire entrepreneur who founded Dyson Ltd. He is best known as the inventor of the dual cyclone bagless vacuum cleaner, which works on the principle of cyclonic separation. According to the ''Sunday Times'' Rich List 2022, he is the second richest person in the UK with an estimated net worth of £23 billion. He served as the Provost of the Royal College of Art from August 2011 to July 2017, and opened a new university, the Dyson Institute of Engineering and Technology, on Dyson's Wiltshire campus in September 2017. Early life and education James Dyson was born 2 May 1947 in Cromer, Norfolk, one of three children, and named after his grandfather, James Dyson. He was educated at Gresham's School, an independent boarding school in Holt, Norfolk, from 1956 to 1965, when his father died of prostate cancer. He excelled at long-distance running: "I was quite good at it, not bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telegraph
Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined and such systems are thus not true telegraphs. The earliest true telegraph put into widespread use was the optical telegraph of Claude Chappe, invented in the late 18th century. The system was used extensively in France, and European nations occupied by France, during the Napoleonic era. The electric telegraph started to replace the optical telegraph in the mid-19th century. It was first taken up in Britain in the form of the Cooke and Wheatstone telegraph, initially used mostly as an aid to railway signalli ...

Air Purifier
An air purifier or air cleaner is a device which removes contaminants from the air in a room to improve indoor air quality. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke. The commercially graded air purifiers are manufactured as either small stand-alone units or larger units that can be affixed to an air handler unit (AHU) or to an HVAC unit found in the medical, industrial, and commercial industries. Air purifiers may also be used in industry to remove impurities from air before processing. Pressure swing adsorbers or other adsorption techniques are typically used for this. History In 1830, a patent was awarded to Charles Anthony Deane for a device comprising a copper helmet with an attached flexible collar and garment. A long leather hose attached to the rear of the helmet was to be used to supply air, the original concept being that it would be pumped using a double bellow ...
