Counting Objects On Conveyors TRIZ Cases
- Proximity Sensor Calibration for Reflective Surfaces
A proximity sensor detects peak intensity of reflected signals to determine distance from a surface.
- VCSEL Optical Feedback System for Laser Power Control
A self-calibrating optical feedback loop detects emitted light and dynamically adjusts the VCSEL drive current to eliminate manual calibration steps.
- Dense Multi-Axis Photosensitive Array for Motion Sensing
A dense multi-axis array of photosensitive elements detects motion via differential photocurrents, resolving signal dropouts during off-axis movement.
- Automated Larvae Counter Using Optical Detection and Gravity Flow
An automated larvae counter replaces manual sampling with optical detection and gravity flow, improving measurement precision while reducing labor intensity.
- Folded Illuminating Path for Uniform Far-Distance Symbol Reading
Extending the illuminating path length beyond the imaging path increases light throughput and return signal strength for far-out symbols.
- Optoelectronic Object Detection Using Pre-Classification
Pre-classifies interfering light objects outside the detection region to prevent false negatives caused by depolarizing materials.
- Optical Limit Switch with Slit Plunger for Position Detection
A limit switch uses a slit in the plunger to modulate light incidence on a receiver, enabling signal output based on displacement.
- Modular Light Curtain Status Module for Sealed Field Installation
A modular plug-in accessory with an omni-directional light indicator connects to a light curtain end cap.
- Integrated Optical Finger Navigation Module with Ambient Light Sensor
An integrated optical finger navigation module combines infrared sensing and ambient light detection on a single substrate.
