  2. Unibit - Wikipedia

    en.wikipedia.org/wiki/Unibit

    Unibit may refer to: Unibit (drill bit), a roughly conical drill bit with a stairstep profile; Unibit (unit), 1 bit of information; Unibit PLL, a type of phase-locked ...

  3. Sharpening - Wikipedia

    en.wikipedia.org/wiki/Sharpening

    Sharpening these implements can be expressed as the creation of two intersecting planes which produce an edge that is sharp enough to cut through the target material. For example, the blade of a steel knife is ground to a bevel so that the two sides of the blade meet.

  4. Drill bit - Wikipedia

    en.wikipedia.org/wiki/Drill_bit

    A unibit (often called a step drill bit) is a roughly conical bit with a stairstep profile. [11] Due to its design, a single bit can be used for drilling a wide range of hole sizes. Some bits come to a point and are thus self-starting.

  5. GNU Unifont - Wikipedia

    Most Western script glyphs can be defined as 8 pixels wide, while other glyphs (notably the Chinese–Japanese–Korean, or CJK set) are typically defined as 16 pixels wide. The unifont.hex file contains one line for each glyph. Each line consists of a four-digit Unicode hexadecimal code point, a colon, and the bitmap string.

  6. Acutance - Wikipedia

    en.wikipedia.org/wiki/Acutance

    Acutance in the left line was artificially increased by adding a one-pixel-wide darker border on the outside of the line and a one-pixel-wide brighter border on the inside of the line. The actual sharpness of the image is unchanged, but the apparent sharpness is increased because of the greater acutance.

  7. Video line selector - Wikipedia

    en.wikipedia.org/wiki/Video_line_selector

    The video signal input is 75 Ω terminated or connected to the video output for a monitor. The amplified video signal is connected to the inputs of the H- und V-sync detector circuits. The H-sync detector outputs the horizontal synchronisation pulse filtered from the video signal. This is the line synchronisation and makes the lines fit vertically.

  8. Units of information - Wikipedia

    en.wikipedia.org/wiki/Units_of_information

    In particular, if b is a positive integer, then the unit is the amount of information that can be stored in a system with b possible states. When b is 2, the unit is the shannon, equal to the information content of one "bit". A system with 8 possible states, for example, can store up to log 2 8 = 3 bits of information. Other units that have ...

  9. Grindstone - Wikipedia

    en.wikipedia.org/wiki/Grindstone

    A grindstone, also known as grinding stone, is a sharpening stone used for grinding or sharpening ferrous tools, used since ancient times. Tools are sharpened by the stone's abrasive qualities that remove material from the tool through friction in order to create a fine edge.
