360 Vis Nav. 2023. The Dyson 360 Vis Nav is a robot vacuum cleaner that was released in May 2023. It has a 360-degree vision system that uses time-of-flight sensors and a camera to map the home and navigate intelligently. It also has a full-width brush bar, a piezo sensor, a HEPA filter, a long-lasting battery, and a smart app.
Dyson series. In scattering theory, a part of mathematical physics, the Dyson series, formulated by Freeman Dyson, is a perturbative expansion of the time evolution operator in the interaction picture. Each term can be represented by a sum of Feynman diagrams. This series diverges asymptotically, but in quantum electrodynamics (QED) at the ...
www.dyson.com. Dyson Limited, d.b.a Dyson, is a Singaporean – British multinational technology company. [7] Founded in 1991 by James Dyson in Malmesbury, England, the company designs and manufactures household appliances such as vacuum cleaners, air purifiers, hand dryers, bladeless fans, heaters, hair dryers, and lights.
A Birkeland current (also known as field-aligned current, FAC) is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere. In the Earth's magnetosphere, the currents are driven by the solar wind and interplanetary magnetic field (IMF) and by bulk motions ...
A vacuum (pl.: vacuums or vacua) is space devoid of matter. The word is derived from the Latin adjective vacuus (neuter vacuum) meaning "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. [1]
The Dyson V8 is a powerhouse of a vacuum; it’s cordless and features a detachable handle that acts as a second, smaller vacuum perfect for corners or places that are harder to reach with a floor ...
Thermal cutoff. An assortment of thermal fuses. A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (a thermal fuse), or may be reset manually or automatically (a thermal switch).
Cryopump. A cryopump or a "cryogenic pump" is a vacuum pump that traps gases and vapours by condensing them on a cold surface, but are only effective on some gases. The effectiveness depends on the freezing and boiling points of the gas relative to the cryopump's temperature. They are sometimes used to block particular contaminants, for example ...
