**Electronic Badge System**

1. Career Fairs have extremely long lines. Students spend a lot of time waiting in lines for bigger companies, which results in them missing out on other promising smaller companies.
2. While waiting in queues, students have to manually fill out a form with their contact information which wastes time and creates more inefficiency.
3. Career Fairs end up using a lot of paper as students generally print around 15-20 resumes to then hand out to various companies, which is environmentally unfriendly.

**Solution Overview**
The solution involves each student attending a career fair to wear an electronic badge which would display their name and major, and this device would be used to solve the problems mentioned above. Additionally, each company attending the fair would have a unique receiver that can detect the badge whenever a student taps on it. Through the tap 3 distinct things will occur:

1. The virtual queue to eliminate standing in line for longer than 5-10 minutes. Whenever a student wishes to be added to the virtual queue for a company, they would tap on the company’s receiver. This would automatically add them to a virtual queue of the company. Now, they don’t have to worry about standing in long lines as the badge would just slightly buzz to alert them whenever they are ~10-15 students away from being in front of the queue.
a. For smaller companies that don’t have a line longer than 10-15 students, students could just tap the badge on the receiver for the company and be good to go. They would then just stand in the physical line for the company.
b. For bigger companies, the students would just tap their badge on the receiver and then be alerted later by a light buzz or LED screen whenever they are 10-15 students away from being in front of the queue. After the alert, as soon as they get free, they would tap on the company’s receiver again to be removed from the virtual queue. Now they could go to stand in line for the company as the queue would be only 10-15 students.
c. Have a button interface to remove oneself from queues and limit the number of virtual queues per student.

2. Eliminating the need for company-specific check-in by transferring basic contact information (name, phone number, email address, major, sponsorship status) whenever the students tap the system for being added on the virtual queue.

3. Transferring resumes to the company and compiling them into a resume bank.

**Solution Components **

**1. Active RFID system**
a. RFID tag/reader system: The badge would be an RFID tag and the company receiver will contain RFID readers. This will be used to exchange basic contact information and student UIN which will be used to put the student on a virtual queue and complete company check-in.
b. Mini LED screen and buzzer: This will display the position in the virtual queue and buzz when the position in the queue is under 15.
c. Buttons to remove yourself from the queue
d. RFID Antennas: They will periodically ping the RFID tags with updated virtual queue position

**2. Bluetooth Module**
a. Both the tag and receiver will contain a Bluetooth module through which resume will be transferred.
b. Resumes can’t be transferred through RFID due to larger size.

**3. Microcontroller with memory chip** which will receive data from RFID receiver and maintain the virtual queue and contact information database. Additionally, using Bluetooth or wired connection allow PC connection to be established, so that the company can transfer the data to their own personal devices.

**Criterion for Success**
1. An electronic badge that:
a. Allows the student to tap a receiver (see below) that puts him/her on a virtual queue and alerts him/her when next on the queue through light buzzing.
b. Allows him/her to monitor his position in the queue through a small LCD, embedded on the badge.
c. Contains a button so that the student can remove himself/herself from the queue.
d. Allows the student to tap a receiver to transfer necessary contact information as well as a resume file.

2. A receiving system that:
a. Recognizes a badge uniquely and handles the logic for the virtual queue
b. Establishes a connection to the badge and allows contact information & resume transfer. Additionally gives the ability to transfer the data to a PC.
c. Stores and manages all the contact information transferred to it.

Hyun Yi, Lauren White, and Andri Teneqexhi earned the Instructor's Award in the Fall of 2013 for their work on the Environmental Sensing for Firefighters.

"Engineering is all about solving real life problems and using the solutions to improve the lives of others. ECE 445 allows you to actually delve deeper into what this really means by providing students the chance to undergo the engineering design process. This requires taking all of the theoretical knowledge, lab experiences, and ultimately, everything that you have ever learned in life, and applying it to your project. Though, there is structure to the course and deadlines in place to measure your team's progress, the actual design, implementation, and success of your project is all determined by you. Unlike any other course that I have taken, I've gained an appreciation for the utilization and benefits of external resources, unforeseen scheduling delays, delegating tasks, and most importantly, teamwork. I consider ECE 445 to be a crash course into real life engineering and a guide to become a successful engineer." -- Lauren White
