Abstract: A system and method for monitoring medication intake uses vibration signals generated by a kinetic augmentation attachment. The attachment includes a base coupled to a medication container, a spring, and a weight, which produces distinct vibration signatures when the container is placed on a surface. A vibration sensor detects these signals, and a computing device processes them to extract features of the attachment and identify the medication container. The system does not require batteries, enabling long-term, maintenance-free monitoring. The method includes processing vibration signals using frequency analysis and machine learning to recognize different medication containers based on their kinetic signatures.

Abstract: A ground visual question-answering method based on dynamic dual-level visual information fusion includes using a dual-level multiscale network, which is divided into language-guided pixel-level features and region-level features. These two scale branches are combined to predict the final textual answer and ground answer. Furthermore, a question-guided dynamic region-level feature localization network is proposed to locate visual information guided by the question and adaptively assign masks of different sizes to ground answers, thereby enhancing the accuracy of locating and segmenting small targets. Additionally, a cross-modal aggregation module is designed to fuse features from both levels, enhancing the fusion of pixel-level and region-level features to improve the segmentation effect of ground answer masks' edges.
