Abstract: Disclosures relate to a sensor system and arrangements having different sized removable spacers. The spacers may be mixed and matched as needed or desired to compensate for misalignment conditions. Further, different spacer combinations and adjustments may be guided by a security management computing device. Variations in configurations of mounting surfaces, such as door and window assemblies, may be accommodated. Alignment of a transmitter or a receiving device, e.g., a magnetic device, with respect to a transmitter or receiving device despite misalignment of the components due to, for example, uneven surfaces of a door or a window, or a respective frame may be achieved.

Abstract: An audio visual haptic signal reconstruction method includes first utilizing a large-scale audio-visual database stored in a central cloud to learn knowledge, and transferring same to an edge node; then combining, by means of the edge node, a received audio-visual signal with knowledge in the central cloud, and fully mining semantic correlation and consistency between modals; and finally fusing the semantic features of the obtained audio and video signals and inputting the semantic features to a haptic generation network, thereby realizing the reconstruction of the haptic signal. The method effectively solves the problems that the number of audio and video signals of a multi-modal dataset is insufficient, and semantic tags cannot be added to all the audio-visual signals in a training dataset by means of manual annotation. Also, the semantic association between heterogeneous data of different modals are better mined, and the heterogeneity gap between modals are eliminated.
