  2. Ultimate Duck Hunting - Wikipedia

    en.wikipedia.org/wiki/Ultimate_Duck_Hunting

    The goal of the game is to shoot ducks and then collect them with hunting dogs, a concept similar to that of the classic NES game, Duck Hunt. A Nintendo Wii version was released by publisher Detn8 Games in December 2007; touted as the new-found company's first title, [ 1 ] it was originally planned for release in July 2007, [ 1 ] but it was ...

  3. Vernier scale - Wikipedia

    en.wikipedia.org/wiki/Vernier_scale

    A vernier scale (/ v ə r ˈ n iː ˈ ə r / ver-NEE-er), named after Pierre Vernier, is a visual aid to take an accurate measurement reading between two graduation markings on a linear scale by using mechanical interpolation, thereby increasing resolution and reducing measurement uncertainty by using vernier acuity to reduce human estimation ...

  4. Height gauge - Wikipedia

    en.wikipedia.org/wiki/Height_gauge

    The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it.

  5. Vernier acuity - Wikipedia

    en.wikipedia.org/wiki/Vernier_acuity

    Vernier acuity (from the term "vernier scale", named after astronomer Pierre Vernier) is a type of visual acuity – more precisely of hyperacuity – that measures the ability to discern a disalignment among two line segments or gratings. A subject's vernier (IPA: / ˈ v ɜːr n ɪər /) acuity is the smallest visible offset between the ...

  6. Pierre Vernier - Wikipedia

    en.wikipedia.org/wiki/Pierre_Vernier

    The main scale reading is the rightmost graduation that is to the left of the zero on the vernier scale. The vernier reading is found by locating the best aligned lines between the two scales. The 0.02 mm engraving indicates the caliper's accuracy and is the "Vernier constant" for this scale. He was born in Ornans, France, in 1580. He was ...

  7. Nonius (device) - Wikipedia

    en.wikipedia.org/wiki/Nonius_(device)

    On a standard scale of 90 degrees, there are an additional 44–45 concentric circles, with each divided into a specific unit size such that a scale unit on position had an arc of / degrees. [ 2 ] [ 3 ] Thus, the outermost quadrant would comprise 90° in 90 equal divisions, the next inner would have 89 divisions, the next 88 and so on.

  8. Traveling microscope - Wikipedia

    en.wikipedia.org/wiki/Traveling_microscope

    Both vernier reading to 0.01mm or 0.02mm. Microscope tube consists of 10x Eyepice and 15mm or 50mm or 75mm objectives. The microscope, with its rack and pinion attachment, is mounted on a vertical slide, which also runs with an attached vernier along the vertical scale. The microscope is free to rotate n vertical plane.

  9. Vernier spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Vernier_Spectroscopy

    Vernier spectroscopy is a type of cavity enhanced laser absorption spectroscopy that is especially sensitive to trace gases. The method uses a frequency comb laser combined with a high finesse [1] optical cavity to produce an absorption spectrum in a highly parallel manner. The method is also capable of detecting trace gases in very low ...
