A magnetic separator is a device that uses a magnet to remove impurities and other magnetic materials from metal. Magnetic separators can be used before, during, and after production of a material and can be adjusted to attract different types of magnetic materials at varying levels of intensity. Magnetic separators are used for a wide …
In a regular oven, a thin layer of air insulates food from the heat beneath it. This layer of air causes food to be cooked unevenly and slows cooking time down considerably. A convection oven is a type of oven that solves this problem by circulating the air within the chamber by using either one …
A profilometer is an instrument that measures a surface profile to determine its roughness. A surface’s vertical resolution is normally measured at the nanometer level, with lateral resolutions being measured to a less accurate degree. Over the past decade, profilometers have started using laser technology in order to improve the degree to which a surface …
Total Harmonic Distortion (THD) is a measured difference in audio levels between the input audio signal’s harmonics and the harmonics of the output audio signal of an amplifier or other audio device. Output Distortion Level As the signal passes through an amplifier it is always somewhat distorted at its output. The waveform at the input …
True antigravity propulsion involves using a material or technological effect that counteracts the effects of gravity without using aerodynamic lift, electromagnetism, or some other balancing force. Likewise, antigravity does not refer to situations in which an object or person experiences lack of weight such as being in a pool, free fall, or high altitude orbit. …
The four dimensions are concepts in mathematics to describe different shapes. It is easy to understand a first dimension, second dimension and third dimension shape. All things are 3D in the world, but images can be 2D. A first dimension is as easy as a line. However, what is the fourth dimension? The fourth dimension …
The Kelvin Scale is a thermometric scale used in physical science to describe the absolute temperature of an object, substance, or area. While Fahrenheit and Celsius scales measure temperature, the Kelvin Scale defines temperatures relative to an object’s thermodynamic movement. As a result, the Kelvin Scale does not use degrees, but simply a number followed …
Stereolithography is a recently discovered process by which products, especially prototypes, can be constructed one layer at a time by using UV-curable photopolymer resins and a UV laser. While stereolithography cannot create every type of material, it produces a wide variety of products for testing, analysis, or review. Stereolithography can be used for a wide …
Humidity sensors (hygrometers) measure and report the air’s relative humidity. They are used in homes, wine cellars, and working environments that that are so humid that they negatively impact working conditions. Humidity sensors are also used in vehicles, industrial HVAC systems, and meteorological stations to help in the predicting and reporting of weather conditions. How …
Terahertz radiation is a selection of the electromagnetic wave spectrum that propagates at frequencies regarded as the terahertz band. ‘Radiation physics of energetic waves’ defines the terahertz band as tremendously high frequency. The terahertz band can be applied within the bracket of 300 gigahertz (high frequency microwave) and 3000 gigahertz (long wavelength far infrared light). …
