Inspired by the vacancy indicator in the modern parking structure and the project 39 in Fall 2017, we want to design and implement an occupancy detection system for outdoor parking.

The system would consist four modules:
- Detection module: ultrasonic proximity detectors (similar to the parking sensor mounted on car's bumper). Each detector has its emitter and receiver. When the wave hits an object nearby, its reflection would be recorded. With certain wave intensity threshold selected, the detector would know if there is a car parked in its duty range. Detectors would be mounted on parking meters or some support stands on the ground.

- Control module: central management system. It would keep track of spot occupancy by constantly communicating with detectors under its control. Inter-device communication is based on WLAN. Besides, the control module is responsible for notifying users (drivers or parking enforcement) about the parking occupancy information.

- Notification module: parking assistant application. We plan to write a mobile application for our detection system, sharing the updated occupancy information upon inquires. The control module would push the detector feedback into an online data storage. When a user starts an inquiry, the application fetches data and display it to the user.

- Power module: power support of our detection system. We plan to use rechargeable solar cells to power the detection module. But for the power-intensive control module, we may need to use extra power from wall plug for demo purpose.

Smart Frisbee

Featured Project

The idea of this project would be to improve upon the 395 project ‘Smart Frisbee’ done by a group that included James Younce. The improvements would be to create a wristband with low power / short range RF capabilities that would be able to transmit a user ID to the frisbee, allowing the frisbee to know what player is holding it. Furthermore, the PCB from the 395 course would be used as a point of reference, but significantly redesigned in order to introduce the transceiver, a high accuracy GPS module, and any other parts that could be modified to decrease power consumption. The frisbee’s current sensors are a GPS module, and an MPU 6050, which houses an accelerometer and gyroscope.

The software of the system on the frisbee would be redesigned and optimized to record various statistics as well as improve gameplay tracking features for teams and individual players. These statistics could be player specific events such as the number of throws, number of catches, longest throw, fastest throw, most goals, etc.

The new hardware would improve the frisbee’s ability to properly moderate gameplay and improve “housekeeping”, such as ensuring that an interception by the other team in the end zone would not be counted as a score. Further improvements would be seen on the software side, as the frisbee in it’s current iteration will score as long as the frisbee was thrown over the endzone, and the only way to eliminate false goals is to press a button within a 10 second window after the goal.
