Optical encoders are the most accurate of the standard styles of encoders, and the most commonly used in industrial automation applications. When specifying an optical encoder, it's important that the encoder have extra protection built in to prevent contamination from dust, vibration and other conditions common to industrial environments.
The "Slide Controller" is an Option Pak that connects to the underside of a Nintendo DS, making the entire device act as an optical mouse. [12] It launched as a Japan-exclusive on August 3, 2007. The Slide Controller is bundled with the game Slide Adventure MAGKID. The Mag Kid is a small magnet centered on the touchscreen.
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.
M-DISC's design is intended to provide archival media longevity. [3] [4] M-Disc claims that properly stored M-DISC DVD recordings will last up to 1000 years. [5]The M-DISC DVD looks like a standard disc, except it is almost transparent with later DVD and BD-R M-Disks having standard and inkjet printable labels.
Jean-Daniel Nicoud (born 31 August 1938), is a Swiss computer scientist, noted for inventing a computer mouse with an optical encoder and the CALM (Common Assembly Language for microprocessors). [1] He obtained a degree in physics at the École Polytechnique Fédérale de Lausanne (EPFL) in 1963. Around 1965, he became interested in logical ...
In the history of optical storage media there have been and there are different optical disc formats with different data writing/reading speeds.. Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), [1] the same speed of compact disc players without buffering.
The IBM 1231 is an online optical mark reader that can read and score 2000 test answer sheets per hour, depending on downstream operations. [ 6 ] The correct answers for the test can either be entered using a master sheet (like the 1230) or sent to the 1231 using the optional master-mark special feature.
Proprietary human-assisted encoders manually operated by specialists could vastly reduce the incidence of artifacts, depending on playing time and image complexity. By the end of LaserDisc's run, DVDs were living up to their potential as a superior format. DVDs use compressed audio formats such as Dolby Digital and DTS for multichannel sound ...
