Photometry Using Wholly Visual Means TRIZ Cases
- Retrofitted Sensor Monitoring for PLC-Free Manufacturing Lines
Retrofitted light, sound, heat, or pressure sensors capture machine operating states and send real-time line data without PLC wiring.
- Optical Keyboard Interface Using DMD Light Patterns for Secure Data Transfer
Keystrokes are encoded as DMD-generated light patterns and sent through an optical channel to reduce electronic eavesdropping risk.
