Wave Based Measurement Systems TRIZ Cases

Overlapping feed projections and metal-layer openings let one radar antenna transmit and receive with isolation while reducing area and extra couplers.

A dual transparent cover with motor-driven stretching wipes cylindrical sensors clean, including high-viscosity contaminants, with less complexity.

Flat-top pulse shaping confines phase shifts to pulse edges, preserving coherence at higher fiber laser power for coherent LADAR.

Shared bit-line output from avalanche photodiode counters cuts wiring area while controlling delay, resistance, and signal interference.

Pressurized airflow and washer fluid are integrated in one sensor housing to keep the lens clean while limiting debris interference and drag.

A localized heat conduction substrate moves laser heat into the support board, improving LiDAR stability without adding module bulk.

Complex shaping coefficients let separate antenna panels boost gain and angular resolution while suppressing gap-induced secondary lobes.

Counter-propagating pump and signal paths confine excitation in a rare-earth planar waveguide, suppressing ASE and parasitic oscillation.

Two dielectric blocks placed across a patch antenna center raise gain while reducing radiating elements, feed length, and transmission loss.

A Ge-on-Si iTOF pixel uses band barriers and separated carrier collection to boost 900 nm absorption while limiting dark current.

Opposed mirrors and a grating waveguide enable 2D optical scanning with simpler structure, less wiring, and better vibration resistance.

A Ge-on-Si pixel structure boosts infrared absorption while band barriers and doped Si collection regions suppress dark current in iTOF sensing.

Counter-rotating reference signals on a ring cable create a common low-noise phase reference across phased array receiver-exciter units.

Block copolymer self-assembly creates sub-100 nm photodetector surface structures that boost near-infrared absorption at small pixel pitches.

Threshold-based pixel response validation distinguishes laser types, rejects false pulses, and improves long-range detection of low-reflectivity targets.

Optical upconversion and lens-coupled single-mode fibers separate RF sources before detection, improving dynamic range and real-time angle finding.

Independent TEC cooling and heat spreading let multiple optically coupled PIC dies share one compact package with better thermal isolation.

A monolithic SPAD receiver uses pipelined digital averaging to replace analog LIDAR front ends and improve range and intensity processing.

Curved and axial end sections in a sensor seal ring suppress friction-driven twisting, preserving watertight sealing during setting operation.

A vector control array steers a 24-GHz phased array beam continuously without costly high-frequency phase shifters, cutting radar size and cost.
