The objective of the green logistics distribution model is to minimise environmental pollution and energy usage by employing clean energy, optimising transport routes and enhancing transport efficiency. Nonetheless, current studies on green logistics distribution models and warehousing planning exhibit certain drawback, such as imprecise location accuracy and decreased distribution revenues. To overcome these challenges, this paper proposes a novel approach that combines inertial measurement unit (IMU) and binocular vision, leveraging multisource information positioning. Specifically, the method integrates data collection and preprocessing modules to gather crucial logistics distribution task information, encompassing IMU data, image data and vehicle data. The visual and inertial positioning module consists of two components: visual positioning based on the grey centre method and IMU positioning based on the integral essence. Finally, an adaptive Kalman filter is employed to merge the results of visual positioning and IMU positioning, thus producing the ultimate logistics vehicle positioning result. The proposed method effectively addresses existing challenges in the green logistics distribution model and warehouse planning. In particular, the experimental results demonstrate that the algorithm proposed in this study reduces the location error by 8%. Furthermore, logistics and distribution costs are reduced by 11 %, contributing to the promotion of sustainable and environmentally friendly logistics operations.
In this paper, an innovative active seat suspension system for vehicles is presented. This seat suspension prototype is built with a shear guidance mechanism, an air spring, a hydraulic shock absorber and end-stop buffers. The acceleration particular signals are measured by using Inertial Measurement Units (IMUs) placed on the seat and the human head. As the excitation, the horizontal vibrations are applied. As an alternative to the classical Fourier approach, the Wavelet Transfer Function (WTF) is introduced to describe the effectiveness of particular seat suspension. In both of the system cases, the human head reaction is investigated by using the Matlab package.

Background and objective: The purpose of this paper is to provide a method for supporting navigation in bronchoscopy based on measurements of absolute orientation of a tip of a bronchoscope and the length a bronchoscope is pushed in the lumen of an examined bronchial structure. Methods: A hardware solution is designed and developed for collecting the data related to the absolute orientation of a tip of a bronchoscope and the length a bronchoscope is pushed in the lumen of an examined structure. A software which processes these data and visualizes in real-time the actual location of a bronchoscope tip in the lumen of a digital model of the examined structure (i.e. virtual bronchoscopy) is also designed and implemented. Results: A calibration procedure is developed which constitutes a basis for the operation of the proposed system. A phantom of a tree-like structure is build, imitating the anatomy of a bronchial tree, and the proposed method of navigation is tested for the task of navigating in the lumen of the phantom to user-selected target locations. Conclusion: A method has been proposed and tested for Inertial Measurement Unit (IMU)- based support of navigation in bronchoscopy.

Praca przedstawia założenia i konstrukcję układu do pomiaru orientacji obiektów. Układy tego typu składają się z akcelerometrów, żyroskopów oraz magnetometrów. Informacje pomiarową stanowią kąty obrotu wokół poszczególnych osi układu trójwymiarowego XYZ. Wyniki pomiarów są obarczone błędami wynikającymi ze sposobu pomiaru oraz wpływu różnego rodzaju zakłóceń, głównie pola magnetycznego Ziemi. W celu otrzymania wiarygodnych pomiarów i informacji o orientacji obiektu zastosowano filtry cyfrowe.
