Signal Processing TRIZ Cases
- Mobile Cluster Audio Adjusting via Autonomous Sound Fingerprinting
Autonomous sound fingerprinting using mobile devices resolves echo and crowd noise interference while maintaining high power efficiency.
- Hearing Aid Feedback Detection Using Dual Algorithm Units
Dual feedback detection units multiply probability by weighting factors to suppress whistling while avoiding signal artifacts.
- Wireless Stereo Sleep Mask with Adjustable Speakers
Adjustable speakers in a wireless sleep mask eliminate cable entanglement while maintaining reliable audio output across different head shapes.
- Loudspeaker Selection via Low Frequency Response Database
Channel configurator selects loudspeakers using pre-measured low frequency response data for accurate sound rendering.
