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

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
![Page 10: Remember DOS- Disk Operating System? … · 26/8/2015 · Remember DOS- Disk Operating System? The pointed hair boss remains clueless. What would you rather have? A computer or an](https://reader036.fdocuments.us/reader036/viewer/2022081407/605134a43cfeba2e1d1bf254/html5/thumbnails/10.jpg)
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

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
![Page 37: Remember DOS- Disk Operating System? … · 26/8/2015 · Remember DOS- Disk Operating System? The pointed hair boss remains clueless. What would you rather have? A computer or an](https://reader036.fdocuments.us/reader036/viewer/2022081407/605134a43cfeba2e1d1bf254/html5/thumbnails/37.jpg)
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
