  2. Pain scale - Wikipedia

    en.wikipedia.org/wiki/Pain_scale

    Pain scale. A Chinese pain scale diagram, rating pain on a scale of 1 to 10. A pain scale measures a patient 's pain intensity or other features. Pain scales are a common communication tool in medical contexts, and are used in a variety of medical settings. Pain scales are a necessity to assist with better assessment of pain and patient screening.

  3. Wong–Baker Faces Pain Rating Scale - Wikipedia

    en.wikipedia.org/wiki/Wong–Baker_Faces_Pain...

    The scale shows a series of faces ranging from a happy face at 0, or "no hurt", to a crying face at 10, which represents "hurts like the worst pain imaginable". Based on the faces and written descriptions, the patient chooses the face that best describes their level of pain. [1] There are 6 faces in the Wong-Baker Pain Scale.

  4. Binary number - Wikipedia

    en.wikipedia.org/wiki/Binary_number

    A binary number is a number expressed in the base -2 numeral system or binary numeral system, a method for representing numbers that uses only two symbols for the natural numbers: typically "0" ( zero) and "1" ( one ). A binary number may also refer to a rational number that has a finite representation in the binary numeral system, that is, the ...

    The code isn't as good at detecting your pain as your parents (who've had years of experience), but it's up to the level of an astute nurse. Remember Baymax's pain scale in Big Hero 6? In the real ...

  6. Binary code - Wikipedia

    en.wikipedia.org/wiki/Binary_code

    A binary coderepresents text, computer processor instructions, or any other datausing a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. The binary code assigns a pattern of binary digits, also known as bits, to each character, instruction, etc. For example, a binary stringof eight bits (which is ...

  7. Morse code - Wikipedia

    en.wikipedia.org/wiki/Morse_code

    Chart of the Morse code 26 letters and 10 numerals [1]. This Morse key was originally used by Gotthard railway, later by a shortwave radio amateur [2]. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs.

  8. Bit numbering - Wikipedia

    en.wikipedia.org/wiki/Bit_numbering

    When the bit numbering starts at zero for the least significant bit (LSb) the numbering scheme is called LSb 0. [1] This bit numbering method has the advantage that for any unsigned number the value of the number can be calculated by using exponentiation with the bit number and a base of 2. [2] The value of an unsigned binary integer is therefore.

  9. Two-out-of-five code - Wikipedia

    en.wikipedia.org/wiki/Two-out-of-five_code

    A two-out-of-five code is a constant-weight code that provides exactly ten possible combinations of two bits, and is thus used for representing the decimal digits using five bits. [1] Each bit is assigned a weight, such that the set bits sum to the desired value, with an exception for zero. According to Federal Standard 1037C : the usual ...
