Optical Sensor Emission Sequencing for Faster Target Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human sensor systems that split a detection range into multiple regions and detect them sequentially from one end are inefficient, leading to prolonged detection times for targets entering the range.
Innovation Solution
An information processing system equipped with an optical sensor having multiple independently controllable light emitting regions, which emits light sequentially following a specific sequence where adjacent regions do not emit light successively, unless a target is detected within the range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple regions are detected sequentially from one end of the detection range, then the detection process is simple to implement, but the time required to detect a target increases significantly
Solution Approach 1:
The detection range is divided into multiple regions corresponding to multiple light emitting regions. Instead of detecting all regions sequentially from one end, the system segments the detection process by allowing multiple light emitting regions to emit light simultaneously in an optimized sequence, reducing overall detection time while maintaining implementation simplicity
Solution Approach 2:
The light emission sequence is dynamically optimized based on the detection requirements. The processor controls the plurality of light emitting regions to emit light in a specific sequence where adjacent regions do not successively emit light, creating a dynamic detection pattern that reduces time loss compared to static sequential detection from one end
2Device complexity
If adjacent light emitting regions emit light successively, then the detection sequence is simple, but the light emitting regions overheat and their lifespan decreases
Solution Approach 1:
The light emitting regions operate in a periodic pattern where adjacent regions alternate their emission cycles. Instead of successive emission, each light emitting region emits light periodically with other regions, allowing cooling intervals between emissions. This periodic action reduces heat accumulation and extends the lifespan of the light emitting regions while maintaining detection effectiveness
Solution Approach 2:
The processor pre-establishes an optimized light emission sequence that prevents adjacent light emitting regions from emitting light successively. This preliminary arrangement of the emission pattern avoids overheating before it occurs, ensuring reliable operation and extended lifespan of the light emitting regions
