Close-Range Type Systems TRIZ Cases
- Optical Bandwidth Coverage Determination for Li-Fi Systems
Computing device calculates optical bandwidth coverage from configuration and lighting data, resolving radiofrequency interference limitations.
- Rotating Identifiers in Light-Based Positioning Systems
Luminaires transmit rotating identifiers via light signals to prevent unauthorized mapping while maintaining accurate navigation.
- Visible Light Source Array Positioning Without Optical Receiver
A visible light source array controller determines luminance patterns from geographical data to enable direct position detection by a mobile terminal.
- Emergency Lamp Interface Using Invisible Wavelength Data Transmission
Invisible ultraviolet pulse-width modulation transmits lamp parameters without altering perceived brightness or disturbing third parties.
- Orange Nanowire LEDs for Hybrid Lighting and Optical Wireless
Replacing YAG phosphors with InGaN orange nanowires overcomes degradation limits while enabling 1.06 Gbps optical wireless communications.
- White LED Optical Transmitter Waveform Correction
A white LED transmitter uses wavelength-selective detection to isolate fast blue light signals for high-speed data transmission.
