1 Remember DOS- Disk Operating System?

2 The pointed hair boss remains clueless

3 What would you rather have? A computer or an X-Box 360 $398 Laptop computer AMD Sempron Processor 60 GB nard drive DVD/CD Burner Basic programs $ X-Box 360 One controller NO games Wal-Mart Ad

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

5 This was a good idea but was scrapped because the solar powered lights would not provide enough illumination. It will be revisited as solar cells and LEDS become more efficient and brighter

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

7 UNC-Charlotte College of Engineering Buildings Grigg Physics Optoelectronics Duke Centennial ME PE Motor sports Cameron ECE Clean Room Smith ET MAPS EPIC ECE and Civil Engineering New football stadium Bioinformatics

8 Engr 1202 E01 students will need to choose one of two projects Details on each project will be presented to help choose The EE project will require working in the Cameron microelectronics clean room The EE project will require working in the Cameron microelectronics clean room The computer engineering project will be done in EPIC The computer engineering project will be done in EPIC

9 The Engr 1202 EE Project Teams will be formed of 4 to 6 members. Each team will decide on various options to design and fabricate a prototype. Teams will be formed of 4 to 6 members. Each team will decide on various options to design and fabricate a prototype. The EE project will require a one hour time commitment other than the TR 8:OOam slot. The EE project will require a one hour time commitment other than the TR 8:OOam slot. A silicon wafer will be used to fabricate the prototype miniature communications antenna A silicon wafer will be used to fabricate the prototype miniature communications antenna The design will be evaluated on cost, reliability, and manufacturability. The design will be evaluated on cost, reliability, and manufacturability. Each team will submit slide presentation of their design. Each team will submit slide presentation of their design.

10 The Engr 1202 EE Project Research, design, and fabricate a miniature planar antenna for use in: 1) Mobile phone using the PCS frequency of MHz 2) “Bluetooth” and Wi-Fi antenna using the frequency band of MHz 3) RFID antenna using the frequency band of MHz 4) GPS antenna using the frequencies of MHz and 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 Computer Engineering Project Students will form small teams Students will form small teams A programmable robot will be fabricated A programmable robot will be fabricated The robot will need to perform a specific set of commands for maximum grade The robot will need to perform a specific set of commands for maximum grade Work will be done in EPIC Work will be done in EPIC A final report will be required A final report will be required Dr. Conrad will provide additional details Dr. Conrad will provide additional details

12 Communications – the key to technology progress Data, voice, and video are all key elements Data, voice, and video are all key elements Both electrical and computer engineers will play a key and vital role Both electrical and computer engineers will play a key and vital role “Wireless” communications is the dominate form “Wireless” communications is the dominate form The EE project will focus on communications systems and a key element of these system. The EE project will focus on communications systems and a key element of these system.

22 Example of a miniature antenna for a mobile phone/watch

23 From Engr 1201 we will use:

24 Engr 1202 EE project and the clean room 1. To work in the clean room, students must wear clean room garments 2. To work in the clean room, students must pass the required safety test 3. Students need to be aware of the hazards in the clean room at all times

25 Clean Room?

26 Cameron Hall On Craver Road, across from parking lot 16 Microelectronics Clean Room on second floor, room 201

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

28 Students Working in the ECE Microelectronics Clean Room

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

30 Units used in electrical and computer engineering Units Tera Giga – Mega – Kilo – Milli – Micro – Nano – Pico –

31 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

32 How much does it cost to run a 100 watt light bulb Typical cost from Duke Power is $.08/Kw-Hr Convert 100w to Kw (Kw = 10 3 W) 100W=.1 KW For 1 hour a 100w light bulb uses.1 KW-Hr For 24 hours, a 100W light bulb uses (24 hr) x (.1 KW- hr) = 2.4 Kw-Hr/day Cost for 24 hr is ($.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

33 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

34 This analysis can be used for any electrical device Every 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) = $ /yr There will be a questions on this type analysis on the tests

35 Assignment – due next class Review the presentation slides on the project, antennas and units Complete HW 2 – 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 Submit via Homework and lecture slides can be found at under heading Engr 1202,
