Diagnostics Using Light TRIZ Cases
- Optical Tip Tracking Using Light-Emitting Catheter Stylets
A light-emitting stylet and skin-mounted photodetectors track catheter tips in real time, avoiding fluoroscopic radiation and contrast media.
- PPG Light-Emission Control for Accurate, Low-Power Wearable Sensing
This PPG case switches LED modes and sampling rates for motion, rest, and sleep to balance heart-rate accuracy with battery life.
- Integrated Intraoral Scanner with OCT for Surface and Internal Imaging
This case combines an intraoral scanner with OCT to register surface shape and internal cross-sectional oral images.
- Portable Device Micro-Perforation Bio-Sensor for Discreet Health Monitoring
This case integrates light transmission and reception through micro-perforations to monitor health metrics during discreet device use.
- Through-Article Optical Sensing for Movement-Resilient Vital Signs
Optical sensing through an article tracks heart and respiratory rates during movement.
- Interferometric Blood Pressure Measurement with Blood Flow Monitoring
A deformable reflective surface and photoplethysmography combine to calculate blood pressure without trained professional assistance.
- Dentine-Enamel Boundary Detection with Dual-Filter Fluorescence
Dual-passband fluorescence filtering helps a sensor identify dentine-enamel boundaries through saliva, water, and toothpaste.
- Hyperspectral Endometrial Imaging for Non-Invasive Cycle Phase Detection
Spectral biomarkers across 400–1000 nm support accurate, same-cycle identification of the implantation window without biopsy.
- Image Acquisition Device with Adjustable Light Paths and Integrated Sensors
This case integrates adjustable light sources and sensors to align imaging at one focal point while measuring target characteristics.
- PPG Circuit Partial Sampling for Low-Power Biometric Detection
A controller switches between partial and full sampling to limit active photoconverters, reducing power and parasitic-capacitance effects.
- CPR Proximity Sensing for Continuous Compressions and ECG Timing
A proximity sensor times ECG analysis during CPR hand-release phases.
- Optical Fiber Fluorescence Spectroscopy for Parathyroid Perfusion
Fiber fluorescence spectroscopy quantifies parathyroid perfusion during surgery in ambient light.
