Detector Signal Noise Reduction via Multi-Sensor Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Movement sensors often produce noisy output signals, which can affect the accuracy of detectors such as imaging or audio capture modules.
Innovation Solution
An apparatus and method that receive measurement signals from multiple movement sensors placed on the same structure, identify correlations between these signals, and use these correlations to adjust the output signals of detectors, thereby reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If movement sensors are used to detect motion and position, then motion detection capability is improved, but noise is introduced in the output signals
Solution Approach 1:
The patent combines multiple movement sensor signals (first measurement signal from first movement sensor, second measurement signal from second movement sensor) and processes them together to reduce noise. The signals are processed to determine a position of the structure, and this combined processing reduces noise in the output signals compared to using individual sensor signals alone.
2Reliability
If multiple movement sensors are deployed on the same structure, then noise reduction capability is improved, but device complexity increases
Solution Approach 1:
The processing system performs multiple functions using the same input signals: it determines position information from the combined sensor signals, and simultaneously uses this position information to adjust output signals from detectors. This multi-functional approach reduces the need for separate processing systems for each function.
Solution Approach 2:
The patent implements a feedback mechanism where the position determined from movement sensor signals is fed back to adjust the output signals from detectors. The processing system receives output signals from detectors, determines position from movement sensor signals, and adjusts the detector output signals based on this position information, creating a closed-loop feedback system that improves signal accuracy.

AI summary
The application relates to an apparatus, method and computer program for adjusting output signals. The apparatus comprising means for receiving at least a first measurement signal from a first movement sensor and receiving at least a second measurement signal from a second movement sensor wherein the first movement sensor and the second movement sensor are provided on the same structure. The means are also for identifying one or more correlations between the measurement signals and using the identified one or more correlations to adjust at least one output signal provided by at least one detector.
