Run Length Limited
Run-length limited or RLL coding is a line coding technique that is used to send arbitrary data over a communications channel with bandwidth limits. RLL codes are defined by four main parameters: ''m'', ''n'', ''d'', ''k''. The first two, ''m''/''n'', refer to the rate of the code, while the remaining two specify the minimal ''d'' and maximal ''k'' number of zeroes between consecutive ones. This is used in both telecommunication and storage systems that move a medium past a fixed recording head. Specifically, RLL bounds the length of stretches (runs) of repeated bits during which the signal does not change. If the runs are too long, clock recovery is difficult; if they are too short, the high frequencies might be attenuated by the communications channel. By modulating the data, RLL reduces the timing uncertainty in decoding the stored data, which would lead to the possible erroneous insertion or removal of bits when reading the data back. This mechanism ensures that the bound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relay Ladder Logic
Ladder logic was originally a written method to document the design and construction of relay racks as used in manufacturing and process control. Each device in the relay rack would be represented by a symbol on the ladder diagram with connections between those devices shown. In addition, other items external to the relay rack such as pumps, heaters, and so forth would also be shown on the ladder diagram. Ladder logic has evolved into a programming language that represents a program by a graphical diagram based on the circuit diagrams of relay logic hardware. Ladder logic is used to develop software for programmable logic controllers (PLCs) used in industrial control applications. The name is based on the observation that programs in this language resemble ladders, with two vertical rails and a series of horizontal rungs between them. While ladder diagrams were once the only available notation for recording programmable controller programs, today other forms are standardized in I ...

Wireless Local Loop
Wireless local loop (WLL), is the use of a wireless communications link as the " last mile / first mile" connection for delivering plain old telephone service (POTS) or Internet access (marketed under the term "broadband") to telecommunications customers. Various types of WLL systems and technologies exist. Other terms for this type of access include broadband wireless access (BWA), radio in the loop (RITL), fixed-radio access (FRA), fixed wireless access (FWA) and metro wireless (MW). Definition of fixed wireless service Fixed wireless terminal (FWT) units differ from conventional mobile terminal units operating within cellular networks such as GSM in that a fixed wireless terminal or desk phone will be limited to an almost permanent location with almost no roaming abilities. WLL and FWT are generic terms for radio-based telecommunications technologies and the respective devices, which can be implemented using a number of different wireless and radio technologies.

Rahal Letterman Lanigan Racing
Rahal Letterman Lanigan Racing is an auto racing team that has participated in the WeatherTech SportsCar Championship and the IndyCar Series. Headquartered in Brownsburg, Indiana and Hilliard, Ohio, it is co-owned by 1986 Indianapolis 500 winner Bobby Rahal, former television talk show host David Letterman, and businessman Mike Lanigan. The Team Won the Indianapolis 500 twice in 2004 and 2020 with Buddy Rice and Takuma Sato, The team was established in 1991 as Rahal/Hogan Racing, became Team Rahal in 1996, and was known as Rahal Letterman Racing from May 2004 until December 2010. Throughout the team's history in IMSA with factory partner BMW, the team has run under the name BMW Team RLL. CART IndyCar World Series (1991–2003) Following the 1991 CART season, Bobby Rahal left the Galles-Kraco Racing team. Despite consistent top finishes, Rahal won only two races from 1989 to 1991. Likewise, Danny Sullivan left the Patrick Racing team, following a dismal season with the Alfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
