Glossary: DIY Book Scanners and Scanning
Posted: 04 Dec 2010, 00:48
I have run into many new terms reading the forums. Some of them are for cameras, some for computers, and others for yet more specialized pieces of hardware. Please if you have a moment stop here and define those special terms for those folks who are newbees.
newbees = a new member to the forum who is still figuring out the language and the ideas in DIY Book Scanners.
heh ... I spell newbee different, its cause I am BIFF, or rather was... in my time, but I tend to like things plain speak, its more democratic and the various short forms, slang, shorthand texting, and anacronyms drive me a bit crazy.
Thanks =D
Thanks for all the kind words and thanks for the kickin' replies!!!
A different sort of organization may be more suitable and I am open to the idea of this being used for now untill it gets unwieldy. I leave that to Daniel and Petaybee (TPTB).
Petaybee= The Powers That Be (TPTB) from The Powers That Be, a book written by Anne McCaffery and Elizabeth Ann Scarborough.
monostable multivibrator = a circuit in which one of the states is stable, but the other is not—the circuit will flip into the unstable state for a determined period, but will eventually return to the stable state. Such a circuit is useful for creating a timing period of fixed duration in response to some external event. This circuit is also known as a one shot. A common application is in eliminating switch bounce.
R/C = Radio Controlled, in example R/C airplanes (radio controlled airplanes)
'A' size or 'A' series paper sizes = a set of paper sizes established by the International Standards Organization (ISO) that ranges from 2A0 (the largest) to A7 (the smallest). The size of the paper goes down as the number goes up, and each is half the size of the previous i.e. two A4 sheets make up an A3 piece and two A5 sheets make up an A4 sheet.
'A' size -- size in millimeters -- approx inches
2A0 -- 1,189 x 1,682 mm -- 46.8 x 66.2 in
A0 -- 841 x 1,189 mm -- 33.1 x 46.8 in
A1 -- 594 x 841 mm -- 23.4 x 33.1 in
A2 -- 420 x 594 mm -- 16.5 x 23.4 in
A3 -- 297 x 420 mm -- 11.7 x 16.5 in
A4 -- 210 x 297 mm -- 8.3 x 11.7 in
A5 -- 148 x 210 mm -- 5.8 x 8.3 in
A6 -- 105 x 148 mm -- 4.1 x 5.8 in
A7 -- 74 x 105 mm -- 2.9 x 4.1 in
AFAIK = As Far As I Know, internet slang
100 Watt standard light bulb emits about 1710 lumens
lumen (lm) = the luminous flux of light produced by a light source that emits one candela of luminous intensity over a solid angle of one steradian.
luminous flux = Also called luminous power, is the measure of the perceived power of light. The total power output of a light source adjusted to reflect the varying sensitivity of the human eye to different wavelengths of light.
radiant flux = measure of the total power of light emitted by a source.
Candela = One candela of luminous intensity is about the luminous intensity emmitted by a common candle (not quite sure what a common candle is but this seemed close enough for understanding the above)
Steradian =
