Optical Signal Transducers TRIZ Cases
- Airbag Cover Breaking Line Tear Resistance via Optical Feedback
Optical interference signals shaped by tool-generated sound waves control material removal depth for consistent airbag cover tear resistance.
- Photoacoustic Bone Conduction for Acoustic Pressure Body Stimulation
Acoustic pressure vibration and photoacoustic bone conduction are combined to improve massage usability, comfort, and safety without electrodes.
- Optical Deflectable Surface Sensing Without a Microphone Sound Port
Reflected light tracks deflectable surface motion precisely, enabling acoustic sensing without a sound port for better dust and water sealing.
