Alarms TRIZ Cases
- Vehicle Accident Assistance With Secure Audiovisual Evidence
This case combines accident sensors, audiovisual recording, positioning, and tamper-proof server transmission for rescue support.
- Multisensor Patient Monitoring for Fall Prediction and Low-Power Alerts
Pressure, motion, and proximity sensors feed a central server that predicts falls, refines alerts, and reduces false alarms.
- Personal Security Alarm Holder for Automatic Skin-Contact Loss Detection
This case shows how a garment-held alarm holder detects lost skin contact and transmits an alert without user activation.
- Biometric Visitor Management with Integrated Resident Evaluations
Biometric visitor records combine resident evaluations for safer access decisions.
- Wireless Machine Passenger State Monitoring for Elevator Reliability
Wireless polling and self-reported state information identify abnormal machine passengers before elevator instability develops.
- Property Monitoring Alert Correlation for Redundant Alert Reduction
A similarity-based correlation layer combines related property actions into one alert, reducing user distraction and monitoring overhead.
- Laptop Speaker Audio Switching via Embedded Controller for Remote Beeps
The audio processor switches between OS sounds and wireless remote beeps, preserving output without a dedicated speaker.
- Aircraft Ground-Object Monitoring Without Onboard Sensors
Ground-based signals locate aircraft-area objects without onboard sensors.
- Wearable Sonar Proximity Detection for Social Distancing Alerts
Embedded sonar emitters and detectors create a wearable zone that alerts users when people approach too closely.
- Nurse Call Mobile Gateway for Smartphone Alert and Status Data
A dual-path mobile gateway connects nurse call servers to smartphones, delivering alerts and device status data to caregivers.
- Portable Device Impact Detection Using UWB and IMU Tracking
UWB positioning and IMU motion data identify impacts against mapped components and build profiles for maintenance alerts.
- Bed-Presence Monitoring With Two-Way Emergency Alerts
This monitoring case uses bed-presence sensing, local alarms, and feedback so users can cancel alerts and responders confirm action.
