 +===== Memory Wire =====
 +Wire made from a special alloy which changes its molecular structure at a certain temperature causing it to shrink. This effect can usefully be applied to point and signal actuation. Some types require a tension spring to pull it back to its original length while others will return unaided, although a spring is still required to keep the wire tight, it can only pull when shrinking, it cannot push.\\ ​

 +===== Monostable =====
 +An electronic circuit that has a single (mono) stable state and an unstable state, an input will cause the circuit to assume the unstable state, when the input signal is removed and after a predictable delay the circuit will return to the stable state. This behaviour is the basis of most timer circuits.

 +===== Multiplexor =====
  
-A communications device that multiplexes (combines) several signals for transmission over a single medium. A demultiplexor completes the process by separating multiplexed signals from a transmission line. Frequently a multiplexor and demultiplexor are combined into a single device capable of processing both outgoing and incoming signals. ​    \\ A multiplexor is sometimes called a mux and also spelled as multiplexer. ​    \\ [[http://​www.webopedia.com/​TERM/​M/​multiplexor.html|http://​www.webopedia.com/​TERM/​M/​multiplexor.html]]
