Prevent Unauthorized Use of Equipment (300)
Problem: Need to disable equipment function if the user is unauthorized (deter theft and misuse of high value items)
Project Activity Scope (from Technical Overview Chart): Circuits and Devices through Integrated Systems
PNNL Solution:
- Developed semi-passive RF tag with equipment interface to allow external control of functionality
- Tag provided suitable range (>600 ft.), ID codes for over 4 billion tags, effective monitoring and output control, and good service life (>5 years)
- Successfully demonstrated for night vision goggle application
Capabilities Employed to Meet Client Needs: Radio frequency (RF) field theory for antenna design and field propagation; information theory for evaluation of read/write distance effects on data transfer rates; analog and digital electronics design; interface design to night vision goggles to allow function control; surface mount electronics development; prototype RF tag design, fabrication, and evaluation; lab testing; test planning and analysis; documentation of technical basis and results.
