5. The Volt by GM will be an all electric car. Other manufacturers are also introducing all electric cars With more cars becoming hybrid electric and total electric powered, the demand for Electrical and Computer engineers will increase in the auto industry.

6. This was a good idea but was scrapped because the solar powered lights would not provide enough illumination.

7. Opto-electronics (devices that use light) include LEDs or light emitting diodes, solar cells, and fiber optic components

10. The Engr 1202 ECE Project Research, design, and fabricate a miniature planar antenna for use in: • Mobile phone using the PCS frequency of 1850-1990 MHz • “Bluetooth” and Wi-Fi antenna using the frequency band of 2400-2597 MHz • RFID antenna using the frequency band of 860-960 MHz • GPS antenna using the frequencies of 1227.60 MHz and 1575.42 MHz Maximum size of 20mm x 20mm, minimum size of 5mm x 5mm. Width on antenna not less than 1mm. Design to have no sharp corners. Reliability, cost, and manufacturability to also be considered

11. The Engr 1202 ECE Project Teams will be formed of 4 to 6 members. Each team will decide on various options to design and fabricate a prototype. The antenna will be fabricated in the Cameron clean room using a silicon wafer as a base. The design will be evaluated on cost, reliability, and manufacturability. Each team will make a verbal presentation of their design and a final report

21. From Engr 1201 we will use:

22. Engr 1202 ECE and the clean room • A student must take and pass Engr 1202 ECE to get a degree in electrical or computer engineering • To pass Engr 1202 ECE, students must work in the clean room • To work in the clean room, students must wear clean room garments • To work in the clean room, students must pass the required safety test

23. Clean Room?

24. Cameron HallOn Craver Road, across from parking lot 16Microelectronics Clean Room on second floor, room 201

25. Required gowning when working in the ECE Microelectronics Clean Room • Special material garments • Hood • Coveralls • Boots • Face mask • Goggles when working with chemicals • Gloves

26. Students Working in the ECE Microelectronics Clean Room

27. Requirements to work in the ECE Microelectronics Clean Room • Gown in clean room garments at all times • Understand clean room protocols and procedures • Understand the hazards and dangers when working in the clean room • Take and pass a clean room safety test

28. Units used in electrical and computer engineering • Units • Tera - 1012 • Giga – 109 • Mega – 106 • Kilo – 103 • Milli – 10-3 • Micro – 10-6 • Nano – 10-9 • Pico – 10-12

29. Understanding the SI system is essential in engineering • Power – kilovolts, megawatts • Circuits – microamps, picofarads, millivolts • Communications – megahertz, gigahertz • Computer speed – nanoseconds • Time dependence – microseconds, milliseconds

30. How much does it cost to run a 100watt light bulb • Typical cost from Duke Power is $.08/Kw-Hr • Convert 100w to Kw (Kw = 103W) • 100W=.1 KW • For 1 hour a 100w light bulb uses .1 KW-Hr • For 24 hours, a 100W light bulb uses (24 hr) x (.1 KW-hr) = 2.4 Kw-Hr/day • Cost for 24 hr is ($.08/Kw-hr) x (2.4 Kw-hr/day) =$.192/day • Cost for a month is (30 days) x ($.192/day) = $5.76/month • Cost for a year is (365 days) x ($.192/day) = $70.08/year

31. Compare cost to a high efficiency replacement lamp • If an equivalent high efficiency lamp uses 13 watts instead of 100 watts • 13 watts = .013 Kw • (.013 KW-Hr) x (24Hr/day) = .312 KW-Hr/day • ( $.08/Kw-Hr) x (.312 KW-Hr/day) = $.02496/day • ($.02496/day) x (365 days/yr) = $9.11/yr • 100watt light bulb = $70.08/yr • 13 watt light bulb = $9.11/yr • Based on lamp running 24 hours per day, everyday for a year

32. This analysis can be used for any electrical deviceEvery electrical device will show power required to operate it • Typical computer may use 120V, 1.5A • (120V)(1.5) = 180 watts = .180 Kw • (.180 Kw-hr) x ($.08/Kw-Hr) = $.0144/Hr • ($.0144/hr) x (24 hr/day) = $.3456/day • ($.3456/day) x (365 days/yr) = $126.144/yr

33. Assignment – due next class • Review the presentation slides on the project, antennas and units • Complete HW 1 – units work sheet found on the Engr 1202 ECE web site • Answers need to be in scientific notation – one unit to the left of the decimal point Homework and lecture slides can be found at www.ece.uncc.edu/research/clean_room Under heading Engr 1202,
