Visible Signalling Systems TRIZ Cases
- Passive Optical Anti-Tamper System Using Light Pipes
Light pipes detect intrusion by sensing brightness changes, replacing mechanical seals that fail against probing.
- Emergency Call Device Occupancy Signaling Fire Search
Occupant-activated emergency call devices transmit zone presence data to fire alarm panels for responder location tracking.
- Wireless Alarm Extension Trigger Unit
A wireless trigger unit detects internal alarm signals and transmits them to exterior receivers.
- Optical Port Labeling for PoE Cable Compatibility
Optical elements in network ports process light to indicate power compatibility, eliminating physical labels and maintaining high port density.
- Combined Smoke and Carbon Monoxide Detector with Synchronized Alerts
A combined detection device houses smoke and gas particle sensors within a single housing to emit synchronized audible alerts.
- Smoke Detector UI with Single-Color LED and Piezo Buzzer
A smoke detector uses a single-color visual indicator and piezo buzzer to generate distinct audio tones and illumination patterns for alarm, maintenance, and network modes.
- Smoke Detector Light Guide Integration
Integrating a light guide into flow ribs reduces aerodynamic turbulence and accelerates smoke detection.
- Elevator Service Alarm Device for Pit and Car Safety
Integrated service alarm device monitors elevator pit and car position to activate visual and audible warnings.
- Eye-Safe Laser Warning Device Using Beam Segmentation
Beam segmentation via a diffuser reduces power density for eye safety while maintaining effective range beyond 200 meters.
