With more cars becominghybrid electric and totalelectric powered, thedemand for Electrical andComputer engineers willincrease in the auto

industry.

The Volt by GM willbe an all electric car.Other manufacturersare also introducingall 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

The incandescent light bulb is going away

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 andfabricate a prototype.

The EE project will require a one hour timecommitment other than the TR 8:OOam slot.

A silicon wafer will be used to fabricate theprototype miniature communications antenna

The design will be evaluated on cost, reliability,and manufacturability.

Each team will submit slide presentation of theirdesign.

The Engr 1202 EE ProjectResearch, design, and fabricate a miniature planar antenna

for use in:

1) Mobile phone using the PCS frequency of 1850-1990 MHz

2) “Bluetooth” and Wi-Fi antenna using the frequency band of 2400-2597 MHz

3) RFID antenna using the frequency band of 860-960 MHz

4) 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

The Computer Engineering Project

Students will form small teams

A computer related project will be fabricated

Work will be done in EPIC

Dr. Conrad will provide additional details

Communications – the key to technology progress

Data, voice, and video are all key elements

Both electrical and computer engineers will play a key and vital role

“Wireless” 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:

Antennas

How 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 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

Units used in electrical and computer engineering

Units

1. Tera - 1012

2. Giga – 109

3. Mega – 106

4. Kilo – 103

5. Milli – 10-3

6. Micro – 10-6

7. Nano – 10-9

8. Pico – 10-12

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

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 = 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

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

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) = $126.144/yr

There will be a questions on this type analysis on the tests
