Post net US postal service 9. In the reading of the barcodes, the signal can either be modulated across widths or across the heights. Give at least ONE example of a bar code type for each of the modulation techniques. 10. List major types of bar codes?

UPC-A: UPC-E: UPC shipping: EAN 8: EAN 13: Code 39 11. What is the principal application of UPC type bar codes? Grocery Food and Beverage industry, Retail industry 12. Differentiate between an active and a passive RFID tag. Active = uses battery power to transmit and receive passive = receives all power from the antenna RFID adv. Greater automation, flexible manfuact., total quality control 13.

What is a "transponder"? device for receiving radio symbol and automatically transmitting a different symbol 14. Why is a read / write RFID tag referred to as a "travelling data base"? B / C data can be read / written and stored in large amounts and info can be changed 15. The most common application of Magnetic character ink recognition is in MICR 16. List the common features that are used in BIOMETRICS Auto ID. Finger, hand, face, eye, veins 17.

A vision system can be used in automatic identification application. List the types of data it can decode data. Banking, ATM, Retail 18. An automatic identification technique that utilizes a time referenced analog electrical signal based on phase changes of magnetic flux is known as Magnetic stripe 19. Differentiate between a magnetic stripe card and a smart card. MS = credit card, phone card, drivers license, SC = medical records, intelligent access, passport 20.

What is a "smart card"? plastic card w / microprocessor chip inside 21. What are the two main types of smart cards? Intelligent and memory 22. What do you understand by the term "OCR"? optical characteristic recognition 23.

Is it possible to combine OCR and MICR? yes 24. Do Auto ID techniques compete or complement each other? compliment List Auto ID techniques that require no physical contact for data to be transmitted. Smart card 25 List three advantages of RFID. i) Higher automation, Flexible manufacturing, Total QC tracking 25. What is another terminology used for 2-D bar codes? Give some specific examples of 2-D bar codes commonly used in industry. 26.

What is a data matrix? How does it differ from a 1-D or 2-D bar code? CHAPTER 13 Quality control 1. Explain the main principles of total quality management (TQM) and its implementation. Process to flourish, willing of management team, process of continuous improvement, use of multifunctional teams 2. TQM is management approach for continuous quality improvement.

3. Describe the various techniques available for Statistical Process Control. What are the important steps involved in solving SPC problems? Use of control charts: define parameters, predict when process is changing, show when a state of control has been reached, monitor the stable process, pareto diagrams, bar charts, r charts, p charts, c charts 4. What do you understand by the "SIX-SIGMA" philosophy as applied to quality control? Manufacturing process usually by 99.74% and must fall within +/- standard deviations, Cp capability index: determined by dividing the total specification area by the process of capability.

Typically companies have a Cp value of 1.33 and higher manufacturing companies are Cp of 2. Attempt to design or refine your process so the process capability falls easily in specs. 55. What are the design variables for the six-sigma design?
