Wave Based Measurement Systems TRIZ Cases
- Piezoelectric Light Deflector Waveforms for Harmonic Cancellation
Different constant-voltage intervals in piezoelectric drive waveforms cancel harmonic components for steadier, less flickering optical scanning.
- Photoelectric Sensor Aperture Plate for Boresighting Control
An aperture plate standardizes LED emission before the lens, reducing photoelectric sensor boresighting variation without active alignment.
- Monitor Photodiode Layer Stack for Unified RF Fabrication
A semiconductor layer stack limits monitor-photodiode absorption to at most 5% while enabling the same fabrication steps as RF photodiodes.
- Piezoelectric Micromirror Scanning for Rapid Abnormality Detection
Piezoelectric sensing tracks mirror-swing signal fluctuations in a short interval, detecting abnormal operation faster than full-period waveform analysis.
- Scanner Laser Optics for Fast One-Dimensional LIDAR Scanning
A MEMS mirror scans a vertically divergent combined beam in one dimension, speeding LIDAR coverage without housing impingement.
- Signal Quality-Based Time Slot Selection for Co-Channel Radar
By sorting reference signals against quality conditions, the electronic device reserves candidate slots for radar or wireless communication on a shared band.
- Reflective Pupil Relay Optics for Large-Pupil MEMS Scanning
Three magnification mirrors and a stationary Offner relay expand scanned RGB laser light to enlarge the pupil and improve diffractive waveguide coupling.
- Optimal Lissajous Scanning Through Frequency and Phase Compensation
Simulation selects frequency pairs and mapping delays, while modulated drive-phase offsets compensate for timing drift and maintain Lissajous scanning density.
- Ultrasound Band-Pass Filtering with Depth-Adaptive Peak Shifting
A depth-adaptive band-pass filter compensates for frequency-dependent attenuation while keeping ultrasound image texture comfortable for users.
