Ear Treatment TRIZ Cases
- Elastic Helical Coil Ear Canal Cleaning Apparatus
A flexible helical coil strip rotates against the ear canal wall to remove cerumen while minimizing patient discomfort.
- MEMS Bone Conduction Sensor Closed Cavity Noise Reduction
A MEMS-based bone conduction sensor integrates an accelerometer and ASIC chip within a sealed enclosure to capture vocal vibrations directly from the temporal bone.
- Audio Encoding Noise-Floor Adjustment for Voiced Signal Quality
Updating a noise-floor level according to voiced or unvoiced sound degrees reduces excessive noise addition in decoded high frequency signals.
- Spring-less Check Valve for Surgical Handpiece
Removing springs from the check valve reduces moving parts and complexity while maintaining reliable backflow prevention through pulse engine pressure.
- Aural Smoothing System for Vehicle Powertrain Transition Noise
An aural smoothing system generates counteracting tones to mask abrupt sound changes during vehicle powertrain transitions.
- Fiber Bragg Grating Sensor for Simultaneous Strain and Temperature Measurement
A fiber optic sensor array measures body movement and temperature via wavelength shifts in embedded gratings.
- Adaptive ANR Circuit Loop Gain Adjustment for Power Efficiency
ANR circuit adjusts loop gain based on external microphone sound levels to optimize noise reduction.
- Tympanostomy Tube Retainer Axial Folding Radial Deployment
Axial folding of the distal flange bypasses radial clearance limits during insertion, resolving versatility constraints across varying flange sizes.
- Auditory Therapy Frequency Spectrum Analysis Apparatus
Auditory therapy frequency spectrum analysis apparatus calculates representative hearing thresholds across divided bands to determine user groups for targeted acoustic stimulus generation.
- Ear Cleaning Implement with Flexible Tube and Open Cell Foam Head
Flexible tube compresses open cell foam head for safe insertion, then expands to extract trapped ear wax without pushing debris deeper.
- Active Noise Control With Real-Time Modifier Block
A modifier block adapts a nominal electroacoustic model in real time to attenuate narrow-band disturbing noises while minimizing computational complexity.
- Intraocular Shunt Deployment Device With Biased Distal Portion
A biased distal portion positions within the anterior chamber angle to deploy intraocular shunts without external optical apparatus.
- Variable Pulse Rate Stimulation Timing for Cochlear Implants
A medical device filters signals into band-pass channels to determine pulse times from envelope peaks.
- TJR Weighted Filter for Speech Enhancement
A spatially pre-processed target-to-jammer ratio weighted filter adapts noise estimation to preserve target sound signals.
