CCDs containing grids of pixels are used in digital cameras, optical scanners and video cameras as light-sensing devices. They commonly respond to 70% of the incident light (meaning a quantum efficiency of about 70%) making them more efficient than photographic film, which captures only about 2% of the incident light. As a result CCDs were rapidly adopted by astronomers. An image is projected by a lens on the capacitor array, causing each capacitor to accumulate an electric charge proportional to the light intensity at that location. ...

Cloaking device - Philadelphia Experiment. The Philadelphia Experiment was a supposed secret experiment conducted by the U.S. Navy at the Philadelphia Naval Yards at Philadelphia, Pennsylvania, on or before October 28, 1943, which went horribly awry. The experiment was allegedly to cast a vale of radar and possibly optical invisibility or transparency around a ship. Though most mainstream experts argue the incident is an urban legend, a number of people argue that the Philadelphia Experiment could be genui ...

Pin device - Invention of the modern pin. The Sumerians used pins made of iron or bone to hold fabric together as early as 3000 BC. However, the modern pin industry came about more recently in medieval Europe, when scholars needed a method of fastening documents together that could be removed, unlike the common method of using a ribbon or string. Pins were made by drawing a piece of metal into wire, cutting the wire into lengths, and welding the heads in place. Although four thousand pins could be made every hour, the pins could only be put onto c ...

The repository has an interface that allows it to transfer knowledge directly into the mind of the user. It has only ever been seen to download all of the knowledge in it, and never only a portion, and it does this in a few seconds. Usually, this drains all of its power. Only the repository's interface is shown; it is suggested but left unclear whether there is a larger device behind it that holds the information and supplies the power (since SG-1 has considered taking a repository with them the total size of the equipment is p ...

There are three different types of ZigBee devices: ZigBee coordinator: It is the most capable device. It might bridge to other networks, and forms the root of the network tree. It is able to store information about the network. There is exactly one ZigBee coordinator in each network.

Intrauterine devices can be used as emergency contraception to prevent pregnancy up to 5 days after unprotected sexual intercourse, or sexual intercourse during which the primary contraception is believed to have failed (e.g. a condom was used, but it broke). Insertion of a copper-T IUD as emergency contraception is more than 99% effective, making it more effective than Emergency contraceptive pills (ECP or 'morning-after pill'). IUDs may also be used where ECPs are less appropriate: ECP are contraindicated in thos ...

In Unix and Unix-like operating systems, special files support interaction with device drivers. Special files can be created in any directory, but by convention only appear in the /dev hierarchy. Special files are either character special files, which support byte-level I/O, or block special files, which support I/O in larger units. Disk partitions are represented by both character special and block special files. A file system in a partition can be mounted, by a command that associates the partition's block special file ...

A Milky Way Stargate has thirty-nine inscribed symbols on the inner ring. When dialing, this inner ring rotates until the dialed symbol is aligned with the next chevron in the sequence, at which point that chevron engages. In the Stargate SG-1 series, an engaged chevron glows red, and the seventh chevron, always at the top, moves down and up every time a chevron engages. In the original Stargate film, all of the chevrons use this motion, and none of them glow red. With 39 symbols, the Stargate Network in the Milky Way has: 38× ...

In the ninth season of Stargate SG-1, it was discovered that the Ancients, originally called the Alterans, were not native to the Milky Way, but originated from another galaxy more distant from Earth than the Pegasus galaxy. While it is not known what the Stargates in the Origin galaxy look like, their presence is implied by the fact that the Ori (Alterans who remained behind and did not follow the others of their kind to the Milky Way) were able to send Priors (religious messengers) to the Milky Way through a Stargate. Since t ...

In the original movie only one valid set of destination coordinates was known, those to the planet Abydos, and it was thought that only those two Stargates existed. At the beginning of the Stargate SG-1 series, however, a large set of additional valid coordinates were discovered engraved in ruins on Abydos. Because the coordinates pick out stars, and because time leads to stellar drift, other addresses were impossible to dial until Samantha Carter ...

At least some planets possess "secondary" or "backup" Stargates. The second Stargate is normally inactive, with the primary Stargate receiving all incoming wormholes. If the originating Stargate malfunctions (e.g. a power surge) while the wormhole is open, the wormhole automatically "jumps" to the closest other gate in the network. In the case of a planet with two gates, the other inactive gate is used as the backup. On at least one occasion a Stargate was hit by an energy weapon as Stargate SG-1 team members returned to Earth through it, ca ...

The Dynomizer looked something like a radio, and it was not too much of a stretch for people to believe that if a radio could tune in distant radio communications then a similar device could interpret the electrical signals of the body. The blood did not have to be fresh; Abrams performed diagnoses on dried blood samples sent to him on pieces of paper in envelopes through the mail. Apparently Abrams even claimed he could conduct medical practice over the telephone with his machines, and that he ...

Known as yingzhang in China and inkan or hanko in Japan, ink seals have been used in East Asia as a form of written identification since the invention of writing. Even in modern times, seals are still commonly used instead of handwritten signatures to authenticate official documents or financial transactions. Both individuals and organizations have official seals, and they often have multiple seals in different sizes and styles for different situations. East Asian seals usually bear the name of the person or organization represented, but the ...

Securing ones possessions has long been a concern of people throughout the world. Beyond hiding the objects or constantly guarding them the most frequently used option is to secure them with a device. Early solutions included knots to either detect Thief knot, or hamper like the Gordian knot. The first known lock with a key was a pin lock where a cylinder of wood with a hole drilled through its axis was the key. The length of the cylinder was the critical factor. It was strung on a rope hanging out of a hole in a door. Then the key wa ...

LD3s, LD6s, and LD11s will fit 787s, 777s, 747s, MD-11s, L-1011s, and all Airbus wide-bodies. The 767 uses the smaller LD2s and LD8s because of its narrower fuselage. The less common LD1 is designed specifically for the 747, but LD3s are more commonly used in its place because of ubiquity (they have the same floor dimensions so one LD3 takes the place of one LD1).

A PLD is a combination of a logic device and a memory device. The memory is used to store the pattern that was given to the chip during programming. Most of the methods for storing data in an integrated circuit have been adapted for use in PLDs. These include: Silicon antifuses SRAM EPROM or EEPROM cells Flash memory SRAM, or static RAM, is a volatile type of memory, meaning that its contents are lost each time the power is switched off. SRAM-based PLDs therefore have to be programmed every time the circuit ...

There is much interest in reconfigurable systems at present. These are microprocessor circuits that contain some fixed functions and other functions that can be altered by code running on the processor. Designing self-altering systems will require engineers to learn new methods, and will probably require new software tools to be developed. PLDs are being sold now that contain a microprocessor with a fixed function (the so-called core) surrounded by programmable logic. These devices allow the designer to concentrate on adding new features to his des ...
