Projectors TRIZ Cases
- Dual-Band Otoscope Imaging for Middle-Ear Fluid Detection
Visible and infrared illumination with dichroic separation improves detection of water accumulation that visible light may miss.
- Multi-Function Projector Using Metasurfaces for Thin Dual-Mode Illumination
Switch between patterned light and flood illumination with a thin metasurface projector.
- Projection Optical Engine Dust-Proof Structure for Debris Containment
A partition plate and cavity isolate adjustment debris from the optical chamber, preserving projected image quality during alignment.
- Projection Lens Module with Single Gravity-Sensor Rotary Focusing
A rotary adjustment member and single gravity sensor replace multiple sensors, simplifying calculations while improving focusing precision.
- Computer Vision Nutrition Tracking with Event-Driven Analysis
Separate detection and segmentation models analyze selected images to reduce computation while updating calorie notifications.
- Multi-Wavelength Metasurface Projector for Thin Pattern and Flood Illumination
A thin metasurface projector switches between patterned and flood illumination.
- Projection Cabinet Wall-Contact Protrusion for Accurate Image Positioning
A wall-contact protrusion positions the projector accurately and reduces image distortion.
