Wave Based Measurement Systems TRIZ Cases
- Portable Ultrasonic Diagnostic Displays With Dynamic Image Layout
Fixed layouts limit portable ultrasound interaction; flexible display control repositions, rotates, expands, or shrinks content for emergency use.
- Optical Sensor Package with Partition Walls for Crosstalk Control
Partition walls and black epoxy molding separate emitting and receiving units, limiting light crosstalk and improving sensing sensitivity.
- Millimeter-Wave Signal Generation Through Optical Frequency Multiplication
Electrical up-conversion can increase phase noise; this architecture multiplies wideband signals optically, then mixes them with a low-noise single-frequency signal.
- LiDAR Galvanometer With Meandering Bending Axis for Large Scan Angles
Meandering bending-axis segments lengthen the galvanometer axis, reducing structural stress while enabling larger LiDAR torsion angles.
- Flexible-Substrate Piezoelectric Transducer With Hole-Defined Vibration
Individual element fixation and wiring complicate assembly; a continuous piezoelectric element forms movable vibration regions.
- Ultrasonic Transducer Assembly With Narrow Vibration-Suppressing Links
Multiple vibrators are joined by narrow connection portions to stabilize positioning while suppressing vibration transmission between plates.
- 5G NR RF Sensing With Polarization-Based Clutter Rejection
Polarization indicators configure transmit and receive signals in 5G NR sensing to distinguish targets from clutter and reduce interference.
- Ultrasound Self-Test Feedback for Hardware Trend Analysis
Periodic self-tests log ultrasound hardware results and upload them for manufacturer trend analysis and proactive maintenance.
- Breast Ultrasound Sound-Speed Calibration from Mammary Gland Ratio
Radiation-image analysis estimates the mammary gland ratio, enabling sound-speed calibration that clarifies the gland layer in breast ultrasound images.
- Cardiac-Synchronized Elastography for Stable Liver Stiffness
Cardiac-synchronized elastography triggers liver stiffness measurements at defined cardiac events to reduce temporal variability and measurement noise.
