Adaptive Vibration Data Averaging for Aircraft Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft systems face delays in accurately representing vibration data due to averaging methods that result in longer 'recovery times' when data values vary, leading to delayed representation of accurate information on displays for pilots and co-pilots.
Innovation Solution
A method involving a control module that receives data from sensors, calculates a delta between data points, compares it to a reference threshold, and dynamically adjusts the number of data points for averaging, providing immediate indications on displays when the delta exceeds or falls below the threshold, thereby reducing recovery time.

Engineering Contradiction Analysis
1Loss of time
If a set number of samples is used for averaging vibration data, then the averaging process is simple and consistent, but the recovery time increases and tracking of varied data values is delayed
Solution Approach 1:
The patent applies dynamics by making the averaging window size adaptive rather than fixed. The control module dynamically adjusts the number of data points included in the averaging calculation based on real-time comparison of consecutive data values against a threshold. When variation exceeds the threshold, the system reduces the averaging window to accelerate recovery time, thereby resolving the contradiction between simple averaging and fast tracking of varied data.
2Stability of the object's composition
If more data points are averaged, then the data representation is smoother and more stable, but the delay in matching varied data values increases
Solution Approach 1:
The system dynamically adjusts the averaging window size based on data stability assessment. When consecutive data values vary beyond a threshold, the system automatically reduces the number of data points in the averaging calculation, enabling faster tracking of varied values. When data is stable, a larger averaging window maintains smooth representation. This dynamic adaptation resolves the contradiction between data stability and tracking speed.
Solution Approach 2:
The patent changes the parameter of averaging window size based on the calculated delta between consecutive data points. By comparing the absolute difference to a threshold and adjusting the number of data points accordingly, the system optimizes the balance between stability and responsiveness. This parameter change strategy enables the system to maintain data stability during normal operation while quickly adapting to sudden changes.

AI summary
A method and apparatus of displaying data in an aircraft, the method including receiving data, from at least one sensor operably coupled to the aircraft, averaging, by a control module, at least two data points of the received data to define a delta and averaged data, comparing, by the control module, the delta to a reference threshold value, and providing an indication, on a display of the aircraft, of the averaged data based on the comparing.
