Wave Based Measurement Systems TRIZ Cases

Reflected signals become power spectra that reveal oscillation frequency and amplitude, helping distinguish distant objects from clutter.

In-channel and out-of-channel detectors monitor interference while pre-allocated backup channels reduce switching delays and interruptions.

A metasurface element combines polarization control with single-aperture scanning and de-scanning.

An antenna array uses controlled phase and amplitude to create simultaneous near-field plane waves for compact radar production testing.

A dual-array probe combines sensor motion and angle data with used-array information to identify probe position relative to the subject.

Injection-locked transmitters, optical amplifiers, and coherent receivers improve LiDAR power, sensitivity, and range.

Polarization-transforming metasurface optics combine scanning and de-scanning, reducing components, alignment demands, and system size.

Rim-and-spoke conductors and resistors absorb AESA radar interference.

This case uses learned models to estimate compound and harmonic images from fewer ultrasonic transmissions, helping preserve frame rate.

A pre-scan analyzes shear waves and sets push and tracking conditions for accurate elastography across varying tissue firmness.

Varifocal lenses use Fourier patterns for accurate autofocus in uneven lighting.

Use communication data as sensing pilots to reduce overhead and improve resolution.

Multiple light emitters and selective reflect-transmit elements expand measurement viewing to ±60° horizontal and ±6° vertical.

Prioritize overlapping radar and communication transmissions to reduce interference.

Self-mixing sensors detect lens shifts and guide actuators to restore alignment.

A microcontroller adapts compression to hydrophone signals, increasing sonar transmission capacity without larger pressure-hull openings.

This ISAC approach estimates scatterer angles from echoes, reducing reference-signal and uplink feedback overhead in channel reconstruction.

This case combines delay, resampling, and frequency shifting to model carrier- and bandwidth-dependent Doppler effects.

A control circuit uses ground during integration and positive substrate potential during readout, avoiding negative voltage generation.

Combining EMD or VMD features with CNN classification helps distinguish similar polyphase LPI radar signals in low-SNR environments.

A metasurface forms sensed laser patterns, replacing the DOE-lens combination with a thinner projector for depth data acquisition.

An ultrasound transducer module switches impedance between transmit and receive phases, improving sensitivity for deeper imaging.

A defined fiber path and diffusers homogenize phase fronts to reduce pixel variation and thermal error in TOF depth maps.

This case uses resource-existence signaling to avoid unnecessary PRS detection and improve sidelink positioning success and precision.

This pattern projector uses laser diffraction and a metasurface to form sensing patterns while reducing sensor thickness.
