Navigation Instruments TRIZ Cases

An IMU on the rotating scanner sustains localization when dust, fog, or poor visibility disrupt laser-based object detection.

Pre-cached map overlays and density-based POI display cut map clutter, latency, and battery drain during interactive navigation.

Visual symbology and 3D binaural audio show voice-command availability and command source, reducing flight crew distraction and false positives.

Combining position-based and velocity-based distance estimates reduces GNSS noise and smoothing errors for more reliable odometry.

Automatically switching eVTOL navigation displays by airspace, flight rules, and autopilot failure reduces pilot workload and supports safer transitions.

A conformal taxi route with undercarriage alignment cues helps pilots follow complex airport paths while keeping eyes on external scenery.

A central processor directs selected devices to rescan incomplete SLAM map areas, improving indoor localization accuracy while avoiding redundant remapping.

Scheduled charging, location tracking, and probe availability management keep ultrasound machines ready while reducing docking delays and misconfiguration.

Vehicle feature data is weighted by measured positional accuracy against reference positions to keep updated maps precise for navigation.

Parallel satellite and inertial reference navigations detect spoofed signals and maintain accurate emergency navigation without speed errors.

Separate TOLD checks for each flight leg let crews verify alternate-airport runway and weight feasibility before departure and update only when needed.

Updating maneuver values along selected routes reduces redundant graph calculations, speeding digital map updates and path proposals.

Positional data from mobile and IoT devices builds a premises map, making nearby device identification and control far easier at scale.

Crowdsourced trajectories and road topography are fused into hybrid paths, cutting map data load while preserving AV navigation accuracy.

Adaptive processing uses sensor stability and integration time to maintain inertial navigation accuracy as output drift changes over time.

Drone and point-cloud data are mapped to virtual utility assets to speed inspections, flag severity, and report encroachment risks.

Automatic use of drivable surface polygons plus connection and separation graphs cuts manual road graph generation effort while improving map accuracy.

Multimodal wayfinding links portable devices to elevator controls with audio, visual, and haptic guidance for accessible building navigation.

Automatic trigger-based start and end detection lets one driver capture road segment data more consistently, safely, and accurately.

Graphical target and avoidance cues on the flight display cut pilot workload and speed horizontal collision-avoidance maneuvers.

Dynamic mode switching lets an ultrasonic fingerprint sensor detect fingerprints underwater, improving terminal operation after water exposure.

A tile directory links map tiles to versioned object files, cutting duplicate storage and avoiding object re-creation when geometries cross tile boundaries.

User-identified landmarks help align sensor data from different vehicle poses, improving map accuracy in landmark-sparse regions.

Control point networks, GNSS, and laser or LiDAR measurements refine map feature positions despite rubber-sheeting and ground movement.

Structured selection lists organize moving images from multiple mobile terminals, helping users find relevant video with less selection difficulty.

Voice alerts change with update time, using full speech for new vehicle notices and shorter audio for older ones to cut annoyance and distraction.

Roads are divided into mapped cells so lane-specific defects and danger data can be displayed precisely and understood more intuitively.

Wearable sensors, cameras, and SLAM track body pose and location indoors where GPS fails, preserving useful motion data for navigation.

Vehicle drive data and a trained model flag only road changes that alter drivable paths, cutting map update time and compute load.

Encrypted TV broadcast entitlement messages carry checksum data so receivers can verify live GPS authenticity and reject spoofed signals.

Wireless peer location and environmental sensing help guide distracted mobile users along paths that avoid obstacles and collisions.

Route-based searches and point-of-interest selection are combined into one itinerary object, cutting multi-interface travel planning effort.

Corner and line clustering cuts repeated image processing in parking space detection, improving real-time control speed and accuracy.

Known ground landmarks and turret angle measurements recalibrate a vehicle inertial unit without GPS dependence or specialist setup.

Integrity verification in stream processing lets map layers update asynchronously while detecting referential, logical, and syntactical inconsistencies.

Onboard sensors and a controller track roll angle, roll rate, and dynamic critical limits to warn pilots before static or dynamic rollover.

Early yaw-rate detection alerts pilots in hover and guides corrective yaw input to prevent sudden rotorcraft rotation and cut reaction delay.
