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 ...
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.
Two optical sensors (phototransistors or photodiodes) are placed very close to each other to make a linear incremental encoder. When the machine axis moves, the dark marks move under the optical encoders triggering them in succession. If movement is from, for example, left to right, encoder A is triggered first and encoder B afterwards.
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 OSLO software is used by scientists and engineers to design lenses, reflectors, optical instruments, laser collimators, and illumination systems. It is also used for simulation and analysis of optical systems using both geometrical and physical optics. In addition to optical design and analysis, OSLO provides a complete technical software ...
Video Encoders – Axis Communications is a manufacturer of video encoders, which allow analog video signals to be converted into digital format for IP networks. [ 44 ] [ 45 ] Recent models are based on the H.264 video compression standard which reduces bandwidth and storage requirements without sacrificing image quality.
The IBM 1282 is an offline optical reader that is used to read embossed credit card receipts, a mark read field or machine printed characters in three different fonts. [17] It then outputs this data onto a punched card. It was developed and manufactured by IBM Endicott. [18]
This comparison of optical character recognition software includes: OCR engines, that do the actual character identification; Layout analysis software, that divide scanned documents into zones suitable for OCR; Graphical interfaces to one or more OCR engines
