Spin coating is widely used in microfabrication of functional oxide layers on glass or single crystal substrates using sol-gel precursors, where it can be used to create uniform thin films with nanoscale thicknesses. [6] It is used intensively in photolithography, to deposit layers of photoresist about 1 micrometre thick. Photoresist is ...
A rotating-wheel Braille display was developed in 2000 by the National Institute of Standards and Technology (NIST) and another at the Leuven University in Belgium. [1] In these units, braille dots are put on the edge of a spinning wheel , which allows the user to read continuously with a stationary finger while the wheel spins at a selected speed.
Example of a spinner together with a text box, placed above a check box. A spinner or numeric updown is a graphical control element with which a user may adjust a value in an adjoining text box by either clicking on an up or down arrow, by pressing an arrow key down or moving mouse wheel, [1] causing the value in the text box to increase (if the up arrow is held down) or decrease (if the down ...

Together these sensors provide 6 component motion sensing; accelerometers for X, Y, and Z movement, and gyroscopes for measuring the extent and rate of rotation in space (roll, pitch and yaw). Some devices [ 28 ] [ 29 ] additionally incorporate a magnetometer to provide absolute angular measurements relative to the Earth's magnetic field.
In digital logic and computing, a counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock. The most common type is a sequential digital logic circuit with an input line called the clock and multiple output lines.
A USB-pluggable hardware true random number generator. In computing, a hardware random number generator (HRNG), true random number generator (TRNG), non-deterministic random bit generator (NRBG), [1] or physical random number generator [2] [3] is a device that generates random numbers from a physical process capable of producing entropy (in other words, the device always has access to a ...
