A finite-state transducer (FST) is a finite-state machine with two memory tapes, following the terminology for Turing machines: an input tape and an output tape. This contrasts with an ordinary finite-state automaton, which has a single tape. An FST is a type of finite-state automaton (FSA) that maps between two sets of symbols. [1]
Helsinki Finite-State Technology (HFST) is a computer programming library and set of utilities for natural language processing with finite-state automata and finite-state transducers. It is free and open-source software , released under a mix of the GNU General Public License version 3 (GPLv3) and the Apache License .
The section about "Operations on finite state transducers" is a also a bit misleading (though correct) in this respect. Although there is no notion of the intersection of two FSTs it should be pointed out, that this is due to the fact that the language class of regular relations is not closed under intersection (Proof sketch: the intersection ...

The generally accepted approach to morphological parsing is through the use of a finite state transducer (FST), which inputs words and outputs their stem and modifiers. The FST is initially created through algorithmic parsing of some word source, such as a dictionary, complete with modifier markups.
A transducer is a device, usually electrical, electronic, electro-mechanical, electromagnetic, photonic, or photovoltaic that converts one type of energy to another for various purposes including measurement or information transfer (for example, pressure sensors). In a broader sense, a transducer is sometimes defined as any device that converts ...
The Burroughs AN/FST-2 Coordinate Data Transmitting Set (CDTS) was a Cold War military computer system at SAGE radar stations for displaying aircraft tracks and converting them for digital transmission to IBM AN/FSQ-7 Combat Direction Centrals at air defense data centers.
External linear displacement transducers (LDTs) eliminate the need for a hollow hydraulic cylinder rod. Instead, an external sensing “bar” utilizing Hall-Effect technology senses the position of the hydraulic cylinder piston. This is accomplished by the placement of a permanent magnet within the piston. [4]
