Audible Signalling Devices TRIZ Cases
- Unmanned Surfboard Sensing for Rip Current Detection and Rescue
Autonomous optical, thermal, and acoustic sensing maps rip currents, alerts beach users, and helps locate distressed swimmers.
- Marine Mammal Detection via Acoustic Signal Processing
Automated audio processing differentiates biological sounds from background noise, reducing subjectivity in detection reliability.
- Marine Device Trim Control Using GPS and Bathymetry Data
A marine device trim system uses GPS and bathymetry data to adjust actuator position.
- Wind Turbine Mooring Ties with Draw Mechanisms
Segmented ties and draw mechanisms maintain stable mooring contact, reducing fuel consumption during harsh sea conditions.
- Autonomous Waterborne Rescue Device Audio Navigation
A buoyant rescue device uses audio sensing and voice recognition to locate drowning victims.
- Rescue Buoy Network for Satellite-Free Communication
Distributed buoys relay signals to bypass satellite failures, enabling rescue activation.
- Boat Navigation Assist Using Outboard Motor Trim-Up Detection
A navigation assist system detects outboard motor trim-up events to alert operators of underwater hazards.
- Bluetooth Beacon System for Marine Hazard Detection
Bluetooth beacons transmit hazard location and owner data to vessels, enabling autonomous collision avoidance in extreme weather.
