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

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

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

Engr 1202 E01 students will do two projects Details on each project will be presented The EE project will require working in the Cameron microelectronics clean room The computer engineering project will be done in EPIC

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. 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 The design will be evaluated on cost, reliability, and manufacturability. Each team will submit slide presentation of their design.

The Engr 1202 EE ProjectResearch, design, and fabricate a miniature planar antenna for use in:Mobile phone using the PCS frequency of 1850-1990 MHzBluetooth and Wi-Fi antenna using the frequency band of 2400-2597 MHzRFID antenna using the frequency band of 860-960 MHz GPS antenna using the frequencies of 1227.60 MHz and 1575.42 MHzMaximum 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

The Computer Engineering ProjectStudents will form small teams A computer related project will be fabricatedWork will be done in EPICDr. Conrad will provide additional details

Communications the key to technology progressData, voice, and video are all key elementsBoth electrical and computer engineers will play a key and vital roleWireless communications is the dominate form The EE project will focus on communications systems and a key element of these system.

Next few slides are from the book:

AntennasHow Wireless Works by Preston Gralla

Early Mobile Phones where not cellular but used a common centrally located tall antenna (similar to police and fire radios) and were limited in the number of phone numbers available

From Engr 1201 we will use:

10 Stages of Design Process

1. Identify the problem/product innovation

2. Define the working criteria/goals

3. Research and gather data

4. Brainstorm/generate creative ideas

5. Analyze potential solutions

6. Develop models/prototypes

7. Make a decision

8. Communicate and specify

9. Fabricate and commercialize

10. Perform post-implementation review and assessment

Engr 1202 EE project and the clean roomTo work in the clean room, students must wear clean room garmentsTo work in the clean room, students must pass the required safety testStudents need to be aware of the hazards in the clean room at all times

Understanding the SI system is essential in engineering Power kilovolts, megawattsCircuits microamps, picofarads, millivoltsCommunications megahertz, gigahertzComputer speed nanosecondsTime dependence microseconds, milliseconds

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

Compare cost to a high efficiency replacement lampIf an equivalent high efficiency lamp uses 13 watts instead of 100 watts13 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/yr13 watt light bulb = $9.11/yrBased on lamp running 24 hours per day, everyday for a year

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/yrThere will be a questions on this type analysis on the tests
