US Patent 3820110, "Eddy current type digital encoder and position reference", gives an example of this type of encoder, which uses a scale coded with high and low permeability, non-magnetic materials, which is detected and decoded by monitoring changes in inductance of an AC circuit that includes an inductive coil sensor.
Many incremental encoders have an additional output signal, typically designated index [2] or Z, [3] which indicates the encoder is located at a particular reference position. Also, some encoders provide a status output (typically designated alarm) [4] that indicates internal fault conditions such as a bearing failure or sensor malfunction.
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. [1] There are two main types of rotary encoder: absolute and incremental. The output of an absolute encoder indicates the current shaft position, making it an angle ...

The World Bank, in a study conducted in 2008, projected triple digit growth for Bangladesh in IT services and software exports. [10] Bangladesh was also listed as one of the top 30 Countries for Offshore Services in 2010–2011 by Gartner. [11] The Internet penetration has also grown to 21.27 percent in 2012, up from 3.2 percent three years ...
DigitalOptics Corporation (DOC) is a San Jose, California-based technology company that designs and manufactures imaging systems for smartphones.DOC’s capabilities include optical design, camera module design and manufacturing, MEMS manufacturing, and image processing algorithms.
the line-coded signal can be used to turn on and off a light source in free-space optical communication, most commonly used in an infrared remote control. the line-coded signal can be printed on paper to create a bar code. the line-coded signal can be converted to magnetized spots on a hard drive or tape drive.
A digital telephone system was introduced in 1983 and mobile phones came in 1992. Before 1980, most of the domestic appliances and equipment were imported, except the one-band radio, but after 1980 many assembly plants for radio, television, audio, and video cassette recorders and players were established.
