Abstract: Computer automated interactive activity recognition based on keypoint detection includes retrieving, by one or more processors, a temporal sequence of image frames from a video recording. The one or more processors identify first and second keypoints in each of the image frames in the temporal sequence using machine learning techniques. The first keypoints are associated with an object in the temporal sequence of image frames while the second keypoints are associated with an individual interacting with the object. The one or more processors combine the first keypoints with the second keypoints and extract spatial-temporal features from the combination that are used to train a classification model based on which interactive activities can be recognized.

Abstract: A battery may include a first electrode, a second electrode, an electrolyte, and at least one acoustic device configured to generate acoustic streaming during a charging and/or a discharging of the battery. The charging of the battery may trigger cations from the first electrode to travel through the electrolyte and deposit on the second electrode while the discharging of the battery may trigger cations from the second electrode to travel through the electrolyte and deposit on the first electrode. The acoustic streaming may drive a mixing and/or a turbulent flow of the electrolyte, which may increase a charge rate and/or a discharge rate of the battery by increasing diffusion rate of cations and/or anions. The mixing and/or the turbulent flow may further prevent a formation of dendrites on the first electrode and/or the second electrode by at least homogenizing a distribution of the cations and/or anions in the electrolyte.
