Navigation Instruments TRIZ Cases
- Aviation Needle Symbol Color Change for Off-Scale Saturation
Color changes on the needle symbol distinguish saturated readings from accurate deviations, eliminating pilot uncertainty during navigation errors.
- Terrain Warning Suppression Using Flight Plan Data
A terrain warning system analyzes aircraft position and intended flight plan to suppress nuisance alerts during low RNP approaches.
- Helicopter Obstacle Display Segmentation
A helicopter obstacle display unit segments alerts and warnings into distinct circular and ring areas.
- Wireless Tracking Map Reconstruction via Trajectory Segmentation
A processing system segments wireless trajectories to reconstruct indoor maps without costly hardware.
- Vehicle Localization via Kalman Filter Odometer Calibration
A computer-implemented method calibrates vehicle odometer parameters using GNSS data and a Kalman filter for real-time localization.
- Digital Road Map Versioning via Hash Chains
A digital road map versioning method uses hash functions to generate version hashes for incremental updates.
- Lifting Device Collision Avoidance via GNSS Sensor Units
GNSS sensor units determine three-dimensional load positions to generate geofences that trigger collision avoidance actions when encroachment occurs.
- Portable Radio Frequency Control Device for Aviation
Automated frequency management reduces manual lookup time and human errors while maintaining flight safety.
- Indoor Positioning Accuracy via User Input Correlation
A positioning system refines location estimates by analyzing user input data against known points of interest.
- Logistic Distance Function for POI Relevance Ranking
A logistic distance function ranks points of interest by viewport proximity.
- Rail Vehicle Orientation Localization via Radar and Track Data
Orientation-based localization determines rail vehicle position using radar sensors and track reference data, avoiding SLAM CPU costs.
- Aircraft Attitude Indicator Roll Angle Alert Symbology
Curved arrow symbology guides pilot corrections during excessive roll angles, reducing confusion and improving recovery.
- In-Vehicle Information Addition System for Safe Hands-Free Communication
An information addition system associates communication partner data with date, time, and voice memo details stored in a personal database.
- Carrier Position Calculation Using Reflected Light Intensity Thresholds
A carrier calculates its position by measuring reflected light intensity and filtering data against predetermined thresholds.
- Motion Sensor Calibration Using Occupancy Maps
A motion sensor calibration system modifies raw measurements using parameters selected from environment perception occupancy maps.
