Encyclopedia topic: Transparent latch A transparent latch is an electronic (additional info and facts about electronic) data storage (additional info and facts about data storage) device (An instrumentality invented for a particular purpose) with a data input (D), an enable input (E) and a data output (Q). Transparent latches are available as integrated circuit (A microelectronic computer circuit incorporated into a chip or semiconductor; a whole system rather than a single component) s, usually with multiple latches per circuit. In synchronous (additional info and facts about synchronous) digital circuit (additional info and facts about digital circuit) s, flip-flop (A backward somersault) s are often preferred to transparent latches. www.absoluteastronomy.com /encyclopedia/t/tr/transparent_latch.htm   (178 words)

Latch - Wikipedia, the free encyclopedia Latches are devices which have no clock input and change output state only in response to data input, while flip-flops have data inputs but change output state only in response to a clock input. A latch is a electronic circuit used to store information in asynchronous sequential logic systems. The latch is constructed from a pair of cross-coupled NAND (negative AND) logic gates. en.wikipedia.org /wiki/Latch   (361 words)

Pull-Open, Push-Close Latch suits furniture and enclosures., Southco Mar 26, 2002 - Electronic Latches use digital technology for locking. Latches featuring an oval flange can be ordered with the pawl perpendicular to the short axis or to the long axis of the oval. This elegant flush mount design, designated the Southco "Point" latch, is available in both curved and angular styles with a range of chrome- and brass-plated finishes to complement a wide variety of application designs. news.thomasnet.com /fullstory/465639/rss/920   (1083 words)

The Basic RS NAND Latch In a commercial latch circuit, either or both of these may be available for use by other circuits. One problem with the basic RS NAND latch is that the input levels need to be inverted, sitting idle at logic 1, in order for the circuit to work. This is necessary if we have a group of latches and want to be sure they all change state (or not) at the same time. www.play-hookey.com /digital/rs_nand_latch.html   (909 words)

HP Labs - Eliminating the Need for Transistors : HP researchers are reinventing the computer at the molecular scale Kuekes was previously awarded a patent on the crossbar latch (U.S. 6, 586,965) in July 2003, and the Journal of Applied Physics report, entitled, "The crossbar latch: Logic value storage, restoration and inversion in crossbar circuits," demonstrates the application of the technology. While a patent for the crossbar latch was granted in 2003, this article reports on experiments that demonstrate that the theoretical construct actually works. "The crossbar latch provides a key element needed for building a computer using nanometer-sized devices that are relatively inexpensive and easy to build." A nanometer is one billionth of a meter or 39/1,000,000,000 inch. www.hpl.hp.com /news/2005/jan-mar/crossbar.html   (1109 words)

Latch PR The first LATCH seats offered are Cosco's Triad child car seat ($79.99), which are available in Kmart stores nationwide, and the Fisher Price Safe Embrace II ($129.99), which will be available this summer at any of the 1,159 Big Kmart or Super Kmart stores that have Kmart Solutions electronic shopping kiosks. LATCH, also known as ISOFIX, is intended to improve the attachment of car seats in vehicles. Approximately three weeks after new owners of Windstar minivans take delivery of their vehicles, they will be mailed $20-off coupons for LATCH car seats that retail for $100 or less and a $35 coupon to be used toward the purchase of a LATCH car seat that is more than $100. www.coscoinc.com /press/pressre/latchsytm.html   (743 words)

Baris Taskin The timing analysis of latch-based circuits, however, is more difficult due to the non-linearity of the timing constraints caused by the time borrowing property.

STMicroelectronics VIPOWER: ELECTRONIC BALLAST FOR REMOVABLE CFL The latch sustain current comes from the resistor R13, it is connected to the tube cathode to reset the circuit when the tube is substituted. During the EOL phase, the protection circuit detects the over-voltage condition and activates the latch stopping the oscillation in the ballast. Using cool ignition, high current values (3, 4 times the nominal value) and voltage values are present in the lamp for a short time, consequently the tube life is reduced. www.st.com /stonline/books/ascii/docs/9456.htm   (2494 words)

The JK flip-flop This consists of two RS flip flops arranged so that when the clock pulse enables the first, or master, latch, it disables the second, or slave, latch. The JK flip-flop is a very versatile device, and is probably the most commonly used form of flip-flop in digital electronic and control circuits. The JK flip flop is the most versatile flip-flop, and the most commonly used flip flop when discrete devices are used to implement arbitrary state machines. web.cs.mun.ca /~paul/cs3724/material/web/notes/node14.html   (395 words)

Addressing Educational Needs of Youth in Today's Society With a large number of children being left unsupervised as more parents are working outside the home or as the percentage of single parents increases, a greater number of children are becoming "latch-key kids" or children who come home from school to an empty house. Inclusion of articles in other publications, electronic sources, or systematic large-scale distribution may be done only with prior electronic or written permission of the Journal Editorial Office, joe-ed@joe.org. Today's child may only have one parent, class sizes in school may be too large for individual attention, and the community may be stretched beyond its ability to provide assistance by outside forces such as gang violence or a struggling economy (see Figure 1). www.joe.org /joe/2000august/comm1.html   (1068 words)

Volume16 Subject: Risks of electronic door locks for automobiles The underlying risk of electronic car door locks is that the state of the lock depends on what a microprocessor believes rather than whether someone has turned a key or pushed a latch button. The risk is subtle: in politics, things are often designed to outwardly resemble their opposites, or to invite confusion or sharply defined contrast (or both) with their opposites. The risks of standing outside a locked car in driving snow on a lightly-traveled mountain road (wearing clothing more suitable for low-altitude desert) should be obvious. www.cs.rutgers.edu /~cwm/NetStuff/Risks/Volume16   (1068 words)

Keyless Keypad Electronic Deadbolt Locksets by: Morning Electronic Since the keyless door lock is a deadbolt and not a latch you will need to lock it manually from the outside by pressing a button or from the inside by turning a small turn piece.

Reversible Electronic Logic Using Switches The energy dissipation for this type of reversible electronic logic (as estimated here) is greater than the dissipation of Drexler's rod logic[18] operated at a cycle time of 100 picoseconds (some 10 times faster than the 1 nanosecond considered here for the RCT). We can indefinitely reduce the energy dissipated by this process by slowing the speed with which we drain charge from the latch. Whether the latch held a "0" or a "1" is immaterial. www.zyvex.com /nanotech/electroTextOnly.html   (15594 words)

CIRCUIT BREAKER In the combination breaker, the bi-metal strip is more likely to be used to trip the breaker internally (by tripping the latch) instead of pulling the contacts apart when heated. In my opinion, circuit breakers should never be used to protect electronic devices such as radios, amplifiers or crossovers. When the current flow reaches a preset level (determined by the current rating of the breaker), the magnetic field in the electromagnet is strong enough to trip the breaker and allow the contacts to open. www.eatel.net /~amptech/elecdisc/cirbrakr.htm   (213 words)

Article from Electronic Experimenter's Handbook, 1978 Edition Whereas the original Elf used a pair of relatively expensive hexadecimal decoders/latch/readouts to monitor the data lines, Elf II uses a pair of conventional 7-segment LED displays to do the same thing.

Elf II, presented here, incorporates all these upgraded features plus new ones, as follows. penguincentral.com /retrocomputing/ElfII   (151 words)

Transparency is http://www.mail-archive.com/cypherpunks@minder.net/msg81918.html sometimes confused with equiveillance (the balance between surveillance and sousveillance).
