Close-Range Type Systems TRIZ Cases
- Visible Light Communication for Mass Transit Vehicles
A visible light communication system uses paired light sources and photodetectors on vehicles and tracks to establish one-to-one data channels.
- LiFi Firmware Updates for Data Center Servers
Digital light transmitters modulate visible light signals to deliver firmware updates directly to managed servers in a data center environment.
- Projector Visible Light Communication via Luminance Modulation
A projector transmits data by modulating signal into specific blinking patterns of visible light emitted toward an indoor wall.
- Optical Communication for Body Mountable Devices Using LED Integration
LED integration enables reliable optical communication in compact wearables, reducing form factor while maintaining signal integrity.
- Fiber Optic Smoke Detection System with Distributed Sensing Nodes
A fiber optic detection system uses light scattering to identify smoke presence and magnitude within a predetermined area.
- Multi-Element VLC Transceiver With Beam Steering
Piezoelectric LED tilting steers visible light beams to improve signal-to-interference-plus-noise-ratio in congested radio-free environments.
- Li-Fi Directional Adaptation for Interference Reduction
Directs high-frequency light signals to optimal transmitter based on low-frequency identifiers, reducing signal interference from multiple sources.
- Camera-Based Illuminant Control for High-Speed Data Transmission
A camera captures images from a controllable illuminant to decode pulse-width-modulated signals.
