A low-force helix (LFH) is a 60-pin electrical connector (four rows of 15 pins) with signals for two digital and analog connectors.
 Each of the pins, visible in the photograph, is twisted approximately 45 degrees between the tip and the white plastic frame which holds all the pins.
 Hence "helix" in the name.
GraphEdit is a utility which is part of the Microsoft DirectShow SDK.
 It is a visual tool for building and testing filter graphs for DirectShow.
 Filters are displayed as boxes, with a text caption showing the name of the filter.
 Pins appear as small squares along the edge of the filter.
 Input pins are shown on the left side of the filter, and output pins are on the right side of the filter.
 A pin connection appears as an arrow connecting the output pin to the input pin.
 Connection mediatypes can be viewed as "properties" on pins and connections.
 GraphEdit can automatically build a filter graph that plays a file.
The Telebrás plug is the old Brazilian telephone plug and socket system.
 It uses a large plug (about 4 cm x 4 cm) with 2 flat metal pins + 2 flat plastic pins.
 Three of the pins have the same orientation and the fourth pin being rotated 90 degrees to make it impossible to plug in the wrong orientation.
The zig-zag in-line package or ZIP was a short-lived packaging technology for integrated circuits, particularly dynamic RAM chips.
 It was intended as a replacement for dual in-line packaging (DIL or DIP).
 A ZIP is an integrated circuit encapsulated in a slab of plastic with 20 or 40 pins, measuring (for the ZIP-20 package) about 3 mm x 30 mm x 10 mm.
 The package's pins protrude in two rows from one of the long edges.
 The two rows are staggered by 1.27 mm (0.05"), giving them a zig-zag appearance, and allowing them to be spaced more closely than a rectangular grid would allow.
 The pins are inserted into holes in a printed circuit board, with the packages standing at right-angles to the board, allowing them to be placed closer together than DIPs of the same size.
 ZIPs have now been superseded by surface-mount packages such as the thin small-outline packages (TSOPs) used on single-in-line memory modules (SIMMs) and dual-in-line memory modules (DIMMs).
A Nintendo game card (trademarked as Game Card) is a cartridge format used to physically distribute video games for certain Nintendo systems.
 The game cards resemble smaller, thinner versions of the Game Pak cartridges for previous portable gaming consoles released by Nintendo, such as the Game Boy or Game Boy Advance.
 The mask ROM chips are manufactured by Macronix and have an access speed of 150 ns.
 The cards contain flash memory, including game data, and a writable portion for saving user data for Nintendo DS and Nintendo 3DS titles.
The Nine of Swords is a Minor Arcana tarot card, also known as the Lord of Cruelty.
 In many countries around Europe it is used as a game card.
 This card has the numerical value of nine.
Rekeying a lock is replacing the old lock pins with new lock pins.
 Locks are usually re keyed to build master-key systems, make a set of locks share a common key, or to eliminate compromised keys.
 Sometimes worn pins are replaced with new pins if the old pins become too short to reach the shear-line.
 The shear-line is the thin line shared by the plug and it's cylindrical housing.
 If a pin sits flush with the circumference of the plug it will allow lock rotation.
 Lock cylinders use different length pins in different combinations to create relatively unique key bitting.
 Most keys have 5 cuts from bow to tip.
 If a key has 5 cuts, the lock has 5 pins.
 Different brand locks each vary in many small ways, this is most true when servicing them.
 Many manufacturers offer product specific manuals.
 Information disclosed in manufacturer manuals is often otherwise difficult to find, as is locksmith material in general.
A scratchcard (also called a scratch off, scratch ticket, scratcher, scratchie, scratch-it, scratch game, scratch-and-win, instant game or instant lottery in different places) is a small card, often made of thin paper-based card for competitions and plastic to conceal PINs, where one or more areas contain concealed information which can be revealed by scratching off an opaque covering.
The Hoosier Lottery is the official state lottery of Indiana, and is the only US lottery that uses the state's nickname as its official name.
 It is a member of the Multi-State Lottery Association (MUSL).
 The Hoosier Lottery sells scratch-off tickets; its draw games include Mega Millions, Hoosier Lotto, Powerball, Cash 5, and Poker Lotto.
Five-pin billiards or simply five-pins or 5-pins (Italian: [biliardo dei] cinque birilli ; Spanish: [billar de] cinco quillas ), is today usually a carom billiards form of cue sport, though sometimes still played on a pocket table.
 In addition to the customary three balls of most carom games, it makes use of a set of five upright pins (skittles) arranged in a "+" pattern at the center of the table.
 The game is popular especially in Italy (where it originated) and Argentina, but also in some other parts of Latin America and Europe, with international, televised professional tournaments (for the carom version only).
 It is sometimes referred to as Italian five-pins or Italian billiards (Italian: biliardo all'italiana ), or as italiana (in Italian and Spanish).
 A variant of the game, "goriziana " or nine-pins, adds additional skittles to the formation.
 A related pocket game, with larger pins, is played in Scandinavia and is referred to in English as Danish pin billiards, with a Swedish variant that has some rules more similar to the Italian game.
