Wave Based Measurement Systems TRIZ Cases
- Double Sideband Backscattering for IoT Carrier Aggregation
A communication device generates control signals to modulate a reference signal via double sideband backscattering.
- Dual-Frequency Ultrasound Transducer for High-Resolution Imaging and Drug Delivery
A dual-frequency ultrasound transducer system transmits at one bandwidth and receives at another to enable high-resolution imaging.
- Radar Stimulator Aircraft for Realistic Target Simulation
A radar stimulator aircraft monitors its position relative to a radar antenna and controls flight to emit synthetic echoes.
- Sensor Assembly PCB Housing Base Integration
Metallized printed circuit board serves as the structural housing base and electromagnetic shield, reducing component count and simplifying assembly.
- Harmonic Radar Drone Detection via Wireless Signal Stimulation
A harmonic radar system stimulates drone wireless devices to extract re-radiated harmonic components for enhanced detection.
- Rotating Polygon Light Pattern Generation for Depth Mapping
Rotating reflective polygons split a light beam into multiple lines, reducing ambient noise accumulation and improving signal-to-noise ratio.
- Jammer Using Continuous Phase Modulation Waveform
A jammer generates a continuous phase modulation waveform with a constant envelope to overlap target receiver passbands.
- Dynamic Superheterodyne Receiver Configuration for Radar Signal Detection
A superheterodyne receiver dynamically determines optimal frequency, angle, and polarization settings to intercept periodic radar signals.
- Lidar Internal Reference Target Calibration via Diffuser and IIR Filtering
An internal reference target with a diffuser reduces speckle noise while an IIR filter compensates for temperature drifts in lidar measurements.
- Ultrasonic Probe Shear Wave Velocity Measurement
An ultrasonic diagnostic apparatus measures tissue hardness by generating and detecting shear waves at multiple positions.
- Optical Antenna Asymmetric Grating Centroids for LiDAR Emission
Offsetting diffraction grating centroids breaks symmetrical waveguide emission, directing more light to one side and improving LiDAR device output intensity.
- Laser Scanning Device Using Telecentric Lens for Aberration Correction
A laser scanning device uses a telecentric lens to correct beam quality after mirror deflection.
- Coherent Optical Radar Signal Generation via Phase-locked Laser Sources
A phase comparator synchronizes dual laser sources to produce coherent high-power optical beams for radar transmission.
