Many laser projectors and galvanometer sets include Digital Multiplexing (DMX) input.
Multiplexing, combining many signals into a single transmission circuit or channel
multiplexing | Wavelength-division multiplexing | Frequency-division multiplexing | Multiplexing |
This type of multiplexing is needed when the customer wants to terminate the DS1 or DS3 in the central office and wants to ‘pick up’ lower level services.
Distributed element filters are used in many of the same applications as lumped element filters, such as selectivity of radio channel, bandlimiting of noise and multiplexing of many signals into one channel.
High-end game port joysticks such as the Microsoft SideWinder rely on multiplexing a proprietary data stream through the 4 standard button inputs and sometimes through the "unused" pins, achieving full support for a rather high number of buttons (e.g. 16 or 20) while special features such as daisy-chaining multiple joysticks, force feedback or joystick programming become possible in some cases.
In February 2008, InPhase Technologies was granted a joint patent with video game company Nintendo for a flexure-based scanner for angle-based multiplexing in a holographic storage system.
Although their mechanisms are different, modelocking lasers and Lyot-filter lasers both produce a comb of multiple wavelengths which can be placed on the ITU grid for Dense Wave Division Multiplexing (DWDM) or used to give each suburban home its own return-signal laser wavelength in a passive optical network (PON) used to provide FTTH (Fiber To The Home).
Multiplexer, an electronic device that accomplishes multiplexing
In the early seventies Stephen Wiesner introduced a primitive called multiplexing in his seminal paper "Conjugate Coding",
Virtual circuit multiplexing or VC-MUX is one of the two (the other being LLC encapsulation) mechanisms for identifying the protocol carried in ATM Adaptation Layer 5 (AAL5) frames specified by RFC 2684, Multiprotocol Encapsulation over ATM.
Gish also proposed multiplexing query sequences to speed up BLAST searches by an order of magnitude or more (MPBLAST); implemented segmented sequences with internal sentinel bytes, in part to aid multiplexing with MPBLAST and in part to aid analysis of segmented query sequences from shotgun sequencing assemblies;
