Digital pattern generators are today available as stand-alone units, add-on hardware modules for other equipment such as a [logic analyzer] or as PC-based equipment.. Stand-alone units are self-contained devices that include everything from the user interface to define the patterns that should be generated to the electronic equipment that actually generates the output signal.
A neckerchief (from neck (n.) + kerchief [1]), sometimes called a necker, kerchief or scarf, is a type of neckwear associated with those working or living outdoors, including farm labourers, cowboys and sailors.
DK-Audio (also known as DK-Technologies) subsequently released the PT5300, which superseded the PT5230, accepting all of its pattern generator modules and included many new options and features developed by DK-Audio. It was the last physical pattern generator directly descending from the original PM5544 to generate the Philips circle pattern.
In software engineering, creational design patterns are design patterns that deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. The basic form of object creation could result in design problems or in added complexity to the design due to inflexibility in the creation procedures.
The builder pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming.The builder pattern separates the construction of a complex object from its representation.
The Necker cube is an optical illusion that was first published as a rhomboid in 1832 by Swiss crystallographer Louis Albert Necker. [1] It is a simple wire-frame, two dimensional drawing of a cube with no visual cues as to its orientation, so it can be interpreted to have either the lower-left or the upper-right square as its front side.
Central pattern generators (CPGs) are self-organizing biological neural circuits [1] [2] that produce rhythmic outputs in the absence of rhythmic input. [3] [4] [5] They are the source of the tightly-coupled patterns of neural activity that drive rhythmic and stereotyped motor behaviors like walking, swimming, breathing, or chewing.
In Middle Low German, it was called necker and in Middle Dutch nicker (compare also Nickel or Nikkel plus Kobolt). [4] The Old High German form nihhus also meant "crocodile", [ 2 ] [ 4 ] while the Old English nicor [ 2 ] [ 4 ] could mean both a "water monster" like those encountered by Beowulf , [ 5 ] and a " hippopotamus ".
