Abstract: A shareable battery pack for a portable ultrasonic apparatus, a trolley, a power supply system, and a portable ultrasonic system. The trolley can be connected to the portable ultrasonic apparatus and/or the shareable battery pack to supply power so as to extend operation time. Alternatively, the trolley is used to support the portable ultrasonic apparatus and/or the shareable battery pack without supplying power to extend operation time. In an embodiment, the shareable battery pack can be removed from the trolley, and then be fixedly connected to the portable ultrasonic apparatus to form an integral unit and serve as an external battery for the portable ultrasonic apparatus. Such design enables the portable ultrasonic apparatus to have extended operation time without relying on the trolley and requires only one shareable battery pack in special situations, thereby enhancing convenience of use.

Abstract: Different automatic tasks are facilitated via outlier detection in datasets using a Weighted Histogram-based Outlier Scoring (W-HBOS). An initial set of features is extracted from a processed dataset. The initial set of features is further filtered by applying robust statistics for size reduction. A second round of automatic feature selection is implemented based on maximum-entropy estimation so that a selected set of features that can give maximum possible information from different dimensions towards detecting anomalies are selected. The selected set of features are transformed to generate principal components that are provided to the W-HBOS-based model for outlier detection. A subset of outliers in one of the directions can be selected and reason codes are identified using back transformation for the execution of a desired automatic task.
