• Linear Array: Position Detection Using Maximal Length Sequences
  or rotation. Popular encoding schemes include the binary code and the Gray code. The Gray code, unlike the binary code, has the characteristic that adjacent code words within the sequence differ only by a single bit. Figure 1 depicts binary and Gray code sequences for n=3 (23 = 8 code words). The sequence...
• Magnetic Stripe
  the parity bit is set to a one. Although the encodation schemes are defined in ISO/IEC 7811, it is only necessary to follow them if the application requires conformance with 7811. Some applications depart from this scheme by allowing different bit density/encoding scheme combinations, others depart...
• PC systems Pony up to PCI Express
  of wires. Each pair runs between the transmitter and receiver of two communicating devices. Signals are differential rather than referenced to ground, reducing problems with electrical noise. Data sent over a PCI Express link incorporates a clock signal (mixed into the data via 8b/10b encoding...
• Feedback for servos
  resolution by a factor of four. Absolute encoding disks create a unique code for each disk position. Multiple tracks with one sensor per track generate a special digital pattern known as Gray code. Gray code's uniqueness stems from only 1 data bit changing state with each count. This eliminates...
• Sensors get smarter
  is magnetostrictive-displacement sensors with directquadrature interface. In the past, programming parameters, encoding outputs, and uploading programs to sensors could only be done at the control location using a discrete converter interface. Advances in digital microelectronics now. Sensors get smarter | Machine Design. Skip...
• History of PNG
  images and/or generic multi-image support; little-endian byte order; Unicode UTF-8 character set for text; YUV and other lossy (non-lossless) image-encoding schemes; and so forth. Many of these topics produced an amazing amount of discussion--in fact, the main proponent of the zipfile idea is still...
• Credit Card Reader Using PIC12C509
  and other applications. This application note describes data formats found on these cards, and details an algorithm to decode that data with suitable hardware. Credit Card Reader Using A PIC12C509 AN727. Credit Card Reader Using a PIC12C509. DATA ENCODING. Author: Andrew M Errington. Data...
• Code Design for Dependable Systems - Preface
  encoding / decoding hardware, modularized organization of encoding /. decoding circuits, and so forth. Chapters 4, 5, 6, and 7 cover topics on matrix code design for high-speed. semiconductor memories. Depending on the application, the matrix code can be designed. to handle bit or byte errors...
• Wireless USB for the factory
  and broadband-radiated interference that characterizes industrial plants. And wireless USB transmissions use a level of security encoding that is comparable to that of wireless Ethernet protocols. Wireless USB equipment is also likely to be relatively inexpensive because consumer electronics is its...
• Integrated Drive Electronics for Brushless DC Motors
  to supply logic signals to the controller. This sytem lends itself to the generation of precise. angular encoding signals and is often specified where greater resolution is desired. Sensorless drives represent one of the newer methods to achieve commutation in BLDCs, although. applications...
