A finite-state machine (FSM) or finite-state automaton (FSA, plural: automata), finite automaton, or simply a state machine, is a mathematical model of computation. It is an abstract machine that can be in exactly one of a finite number of states at any given time. The FSM can change from one state to another in response to some inputs; the ...
Mealy machine. In the theory of computation, a Mealy machine is a finite-state machine whose output values are determined both by its current state and the current inputs. This is in contrast to a Moore machine, whose output values are determined solely by its current state. A Mealy machine is a deterministic finite-state transducer: for each ...

A vending machine is an automated machine that dispenses items such as snacks, beverages, cigarettes, and lottery tickets to consumers after cash, a credit card, or other forms of payment are inserted into the machine or ...
The algorithmic state machine (ASM) is a method for designing finite state machines (FSMs) originally developed by Thomas E. Osborne at the University of California, Berkeley (UCB) since 1960, [1] introduced to and implemented at Hewlett-Packard in 1968, formalized and expanded since 1967 and written about by Christopher R. Clare since 1970. [2 ...
Comparison of pictorial and schematic styles of circuit diagrams Common schematic diagram symbols (US symbols) The circuit diagram for a four-bit TTL counter, a type of state machine. A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit.
MDB originated as a proprietary bus used by CoinCo for their coin-acceptors in the late 1980s and was deployed in high volume in vending machines for Coca-Cola.Coke forced CoinCo to open-source it in 1992 to increase competition, and NAMA released the first version of the standard in 1995, allowing other vendors to compete for the coin-acceptor portion of the vending machines (CoinCo and Mars ...
A coffee vending machine is a type of vending machine that dispenses hot coffee. Some of the machines, particularly older models, utilize powdered instant coffee mixed with hot water, and some of these offer condiments such as cream and sugar. [1] Some newer models fresh-brew the coffee using hot water and ground coffee beans, and some also ...
A newspaper vending machine or newspaper rack is a vending machine designed to distribute newspapers. Newspaper vending machines are used worldwide, and they are often one of the main distribution methods for newspaper publishers. According to the Newspaper Association of America, in recent times in the United States, circulation via newspaper ...
