Stethoscope TRIZ Cases
- Cardiac Foundation Model Using ECG-PCG Signals With Less Labeled Data
A foundation model learns from synchronized ECG and PCG data, cutting labeling effort while supporting detection of atrial fibrillation, murmur, and pulmonary hypertension.
- Multisensor Stethoscope With Ultrasound for Automated Diagnosis
Acoustic and ultrasonic sensing are combined to automate heart, blood pressure, and oxygen measurements in noisy point-of-care settings.
- Cardiac Foundation Model Training With Unlabeled ECG and PCG Data
Pretraining on synchronized ECG and PCG data cuts labeling burden while preserving accurate cardiovascular condition detection.
- ECG-PCG Foundation Model for Non-Invasive Cardiac Detection
Synchronized ECG and PCG pretraining reduces labeled data needs while improving reliable non-invasive detection of cardiovascular conditions.
- Wireless Patient Monitor Cloud Processing for Battery Uptime
Cloud offloading cuts CPU load and heat in a wireless patient monitor, then switches to local processing when network criteria are met.
- Integrated ECG-PCG Sensor for Synchronous Cardiac Signal Capture
A skin-adhered conductive sensor captures ECG and PCG signals at once, removing separate electrodes and manual stethoscope pressing.
