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.

Abstract: Generation and use of a focus quality metric that is intensity independent is described. In one example, the focus quality metric is generated by acquiring an image, such as an image of a patterned surface of a flow cell, and processing all or part (e.g., a sub-region or sub-image) to generate a Fourier transform of the respective image data. By way of example, in one embodiment a discrete Fourier transform may be applied to a sub-region of an image of a patterned flow cell surface. A focus quality metric that is intensity independent may be derived from the Fourier transform of the image data.

Abstract: A method is disclosed herein. The method includes dicing a wafer and applying a mask. The method includes spraying die bond material, at a first temperature, to a surface of the wafer and cooling the die bond material at a second temperature to at least partially solidify the die bond material.
