  2. Luhn algorithm - Wikipedia

    en.wikipedia.org/wiki/Luhn_algorithm

    Luhn algorithm. The Luhn algorithm or Luhn formula, also known as the " modulus 10" or "mod 10" algorithm, named after its creator, IBM scientist Hans Peter Luhn, is a simple check digit formula used to validate a variety of identification numbers. It is described in US patent 2950048A, granted on 23 August 1960. [1]

  3. Pulse-width modulation - Wikipedia

    en.wikipedia.org/wiki/Pulse-width_modulation

    t. e. Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an electrical signal.

  4. Actor model - Wikipedia

    en.wikipedia.org/wiki/Actor_model

    Decoupling the sender from communications sent was a fundamental advance of the actor model enabling asynchronous communication and control structures as patterns of passing messages. [8] Recipients of messages are identified by address, sometimes called "mailing address". Thus an actor can only communicate with actors whose addresses it has.

  5. Asynchronous circuit - Wikipedia

    en.wikipedia.org/wiki/Asynchronous_circuit

    Asynchronous circuit (clockless or self-timed circuit) [ 1 ]: Lecture 12[ note 1 ][ 2 ]: 157–186 is a sequential digital logic circuit that does not use a global clock circuit or signal generator to synchronize its components. [ 1 ][ 3 ]: 3–5 Instead, the components are driven by a handshaking circuit which indicates a completion of a set ...

  6. Modbus - Wikipedia

    en.wikipedia.org/wiki/Modbus

    Modbus or MODBUS is a client/server data communications protocol in the application layer. [1] It was originally designed for use with its programmable logic controllers (PLCs), [2] but has become a de facto standard communication protocol for communication between industrial electronic devices in a wide range of buses and networks.

  7. Universal asynchronous receiver-transmitter - Wikipedia

    en.wikipedia.org/wiki/Universal_asynchronous...

    A universal asynchronous receiver-transmitter (UART / ˈjuːɑːrt /) is a peripheral device for asynchronous serial communication in which the data format and transmission speeds are configurable. It sends data bits one by one, from the least significant to the most significant, framed by start and stop bits so that precise timing is handled ...

  8. Time-Sensitive Networking - Wikipedia

    en.wikipedia.org/wiki/Time-Sensitive_Networking

    Time-Sensitive Networking (TSN) is a set of standards under development by the Time-Sensitive Networking task group of the IEEE 802.1 working group. [1] The TSN task group was formed in November 2012 by renaming the existing Audio Video Bridging Task Group [2] and continuing its work. The name changed as a result of the extension of the working ...
