TRANSCRIPT
Project Overview
Demonstrate the feasibility of wireless power transmission through the example of wireless bridge monitoring sensors.
Goals• Wireless power collection
• Characterization of low power transceivers (TNC’s)
• Develop at least one sensor type
• Separate antennas for power and communication
• Bi-directional serial communication between sensor and base station
• Communication through 1” of concrete
Base Station• MSP430
– Low Power– Institutional knowledge
• TNC– Nordic– TI– Linx
• Interface to PC– USBSerial board
Sensors• Temperature
• Humidity
• Vibration (Accelerometer)
• Force/Strain
• Displacement
• Chemical content (Cl-)
Task AssignmentsMr. Sutton
– Director of Software Development
Mr. Falkenstein– Procurement Director– Director of Antenna Research– CFO
Ms. Ditlevson– VP of Documentation Resources
Mr. McDougle– Director of Hardware Development– Acting President
Risk Analysis/Mitigation• Team skill sets
– Weak on software
• Part availability
• Sensor packaging
• Power requirements
• Leakage from storage element
• RF propagation in concrete
• Uncertain of processing power of base station
• Force majeure
