, our design could maintainthe structural integrity that we desired so that a person can safely ride our bike and brake usingRE-Brake.Although we accomplished most of our goals as we progressed further into our project, uponfurther examination we realized that RE-Brake could be greatly improved. Although our RE-Brakesystem worked for us, it lacked portability and was not interchangeable between bikes. Wedesigned RE-Brake specifically for our bike and all the measurements that we took matched ourdesign and layout, however, our next goal would be to make RE-Brake more modular and to haveit easily fit on various bikes and models.Once the RE-Brake system was attached to the bike [Figure 2a-b], three different tests were run.The first test was

amount of line compensation.The exact amount of time the resistor is inserted before the main contacts close depends of theline length. Therefore, it is important to capture the operation, specifically, the timing of thisresistor switch.Setting up and Running the TestThe class as a whole sets up and runs the test working in teams. Only two hours is allotted forthis test, so the testing cannot be done individually. (In other courses, such as ET 280 ProtectiveRelaying, additional time is allocated so each student can do the testing individually.) The stepsare as follows: 1. Check Circuit Breaker Status a. Check SF6 pressure in the interrupters b. Check air pressure in the pneumatic system. If low, connect compressor to 120 V

𝐸𝑔 is the bandgap energy ofthe semiconductor, for Si, it is 1.1 eV at STC. k is the Boltzmann constant (1.38×10-23 J/K) and 𝐾𝐼is the temperature coefficient of short-circuit current, which is +4.575 mA/K for the chose cell.To study the effect of irradiance, the illumination intensity was varied from 200W/m2 to 1000W/m2 with an increment of 200W/m2. The simulated I-V and P-V curves are shown in Fig. 4. (a) (b) Figure 4. Simulated (a) I-V, and (b) P-V curves of the solar cell at varying

This figure can significantly double to higher values whenconsidering higher occupancy density spaces such as theaters, class rooms, and large meetingrooms.The project revealed high impact on the level of understanding for students. Studentsperformance and project outcomes were assessed against ABET learning outcomes: (a) applyknowledge, techniques and skills to engineering technology activities, (b) apply knowledge ofmathematics, science, and engineering to engineering technology programs, (c) Conduct tests,measurements, calibration and improve processes, (e) Problem Solving: ability to identify
