Respiratory Organ Evaluation TRIZ Cases
- Optical Target Recognition for Precise Radiation Beam Limiting
Optical image recognition aligns the beam limiter with the intended target region, reducing unnecessary radiation exposure during medical operations.
- Wireless Facial-Support Monitoring for Sleep Disorder Diagnosis
Wireless sensors on a facial support capture EEG, EOG, EMG, respiration, and CO2 data to reduce cable-related sleep monitoring errors.
- Camera-Based Apnoea Detection Through Cardiac–Respiratory Signal Separation
Remote cameras separate cardiac and breathing-motion signals to detect apnoea without contact sensors, reducing false positives and patient discomfort.
- Torso Wearable Respiration Metrics for Real-Time Training
Torso sensors convert respiration signals into live visual metrics, helping users align breathing with targets and train heart rate variability.
- Wearable Physiological Monitoring with Adaptive Event Sampling
Adaptive sampling maintains physiological event detection while lowering power use during stable periods and alerting users to likely respiratory events.
- Radar Heart Rate Measurement with Adaptive Harmonics Filtering
Radar-measured cardiorespiratory motion is filtered with respiration-adjusted notch depths to identify heart rate without surgical implants.
- Single-Channel FMCW Radar Localization for Multi-Subject Vital Signs
Joint-sparse recovery separates cluttered radar signals to localize multiple subjects and extract accurate vital signs from one receiver channel.
- Exhaled Nitric Oxide Screening for Rapid Sepsis Risk Assessment
Exhaled NO combined with temperature, heart rate, and respiratory rate forms the SINO score for faster, more specific sepsis-risk detection.
- Eddy Current Damping Sensor for Non-Contact Respiratory Volume
An inductive coil and RLC circuit track chest conductivity changes to measure FEV1, FVC, and breathing rate without skin contact.
