Close-Range Type Systems TRIZ Cases
- Superimposed Light Code Transmission for Seamless File Sharing
Time-varying light components encode file addresses into images, eliminating the need for prior communication setup or manual pairing.
- O-OFDM PWM Dimming for High-Capacity VLC
An O-OFDM generator produces inverted and non-inverted signals to modulate LED current during both PWM on-states and off-states.
- VLC Data Fragmentation Over DMX-512 Networks
A VLC apparatus segments data into DMX packets for transmission over lighting networks.
- VLC AP Coordination Node for Interference Management
A coordination node manages visible light communication access points to prevent signal interference between overlapping coverage areas.
