RF Transmitter / Receiver Test PCB for ASK Link - Custom RF test system for Wayne-Dalton, a garage door opener manufacturer.

Summary: The system is used to test the RKE (remote keyless entry) wireless link operation as part of a larger highly accelerated stress testing (HASS) system. The HASS system tests the electrical controls and electromechanical drive of the customer's OP40XR garage door operator assembly. The larger HASS system was designed by our strategic partner, Electromechanica, Inc., and the system is now part of Wayne-Dalton's production test process.

Petri-Dish Experiment Monitoring / Video Processing System - Custom video processing & control system for the Levin Labs at the Forsyth Institute

Summary: The system is used to track the motion of small organisms like tadpoles, worms & zebrafish and provide control of petri-dish illumination. The system allows the researchers to perform experimentation on organism learning & behavior mechanisms. The system uses an RS-170 analog video camera and BlackFin BF533 DSP to perform image processing and determine the organism centroid coordinates.
