Control Devices TRIZ Cases
- Blood Pump Flow Control via Pressure Sensors
A blood pump uses inflow and outflow pressure sensors to calculate flow rate for precise motor speed adjustment.
- Ventricular Assist Device Software Update Mechanism
Controller initiates wireless updates for implantable ventricular assist devices, stopping the rotor only during verification to avoid invasive surgery.
- Driver Comfort Index via Physiological and Behavioral Sensor Fusion
A control device fuses physiological and behavioral sensor data with driving context to calculate a real-time driver comfort index.
- Bone Conduction Alarm Transmission for Ventricular Assist Devices
Signal processor transmits inaudible alarm signals via bone conduction to a hearing implant.
- External Cardiac Pressuriser for Percutaneous Ventricular Assist
An external pressuriser synchronizes with the cardiac cycle to improve ejection fraction without intravascular implantation risks.
- Magnetic Levitation Blood Pump Flow Rate Estimation
A magnetically levitated blood pump estimates flow rate using impeller position parameters detected by the motor stator.
- Vehicle Mode Transition Inhibition System
A vehicle control system detects improper conditions and inhibits driving mode transitions.
- Blood Pump Suction Detection via Flow Waveform Interpolation
Interpolating power-to-flow data sets identifies suction markers in the diastolic phase, reducing false positives without complex signal processing.
- ECG Signal Control for Extracorporeal Circulatory Support
A control unit evaluates ECG signal amplitude changes to synchronize extracorporeal circulatory support with cardiac cycles.
- Implantable Cardiac Therapy Device Coordinated Pump and Defibrillation
A combined cardiac therapy device coordinates a ventricular assist pump with an implantable defibrillator to manage heart failure and arrhythmia.
- External Drive Unit Purge Line Thermal Contact Cooling
A purge line transfers heat from the motor housing to a circulating medium via thermal contact.
- On-the-Move Range Shifting in Two-Speed Transfer Cases
An electronic control system manages a non-synchronized range clutch in a two-speed transfer case, enabling on-the-move shifting without stopping the vehicle.
