Close-Range Type Systems TRIZ Cases
- Accelerated Optical Keying Beyond 3 dB Bandwidth
Selected radiation output levels let optical transmitters exploit bandwidth above 3 dB attenuation while keeping receiver signals distinguishable.
- Free Space Optical Communications With Blockage-Triggered Power Control
Wireless detection signals monitor the optical path so high-rate FSO transmission can reduce power or stop when blockage indicates human presence.
- Wireless Streetlight Sensors Combining Light Control and Computing
Conventional light controls lack networking; integrated streetlight nodes add wireless communication and distributed computing while managing ambient lighting.
- LED Optical Communication for Low-Complexity Device Data Access
Simple LEDs and light sensors transmit imperceptible signals for reliable device data access without costly IO-Link interfaces.
