Lenovo Legion is a line of consumer-oriented laptops, desktop computers, smartphone, and tablet computers designed, developed and marketed by Lenovo, targeting gaming performance. The first Legion brand laptops, the Legion Y520 and the Legion Y720, were revealed at CES 2017 and succeeded the IdeaPad Y series . [ 1 ]
Computer cooling is required to remove the waste heat produced by computer components, to keep components within permissible operating temperature limits. Components that are susceptible to temporary malfunction or permanent failure if overheated include integrated circuits such as central processing units (CPUs), chipsets , graphics cards ...
In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
Distortion occurs when the transfer function F is more complicated than this. If F is a linear function, for instance a filter whose gain and/or delay varies with frequency, the signal suffers linear distortion. Linear distortion does not introduce new frequency components to a signal but does alter the balance of existing ones.
The Lenovo Legion Go is a handheld gaming computer developed by Lenovo and released in October 2023, as part of their Lenovo Legion line. The device ships with Windows 11 and with the Lenovo Space game launcher.
Most of the electricity in an LED becomes heat rather than light – about 70% heat and 30% light. [1] If this heat is not removed, the LEDs run at high temperatures, which not only lowers their efficiency, but also makes the LED less reliable, shortens its lifespan. Thus, thermal management of high power LEDs is a crucial area of the research ...
The part that converts electricity into heat is called a heating element. Among the applications are: Buildings are often heated with electric heaters where grid power is available. Electric stoves and ovens use Joule heating to cook food. Soldering irons generate heat to melt conductive solder and make electrical connections.
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. [1]
