Abstract: An integrated portable extremely fast charger (XFC) may be installed for heavy-duty off-road vehicles, such as tractors and combine harvesters. The XFC shortens the charging period of plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) by providing >500 kW in a single charger. The proposed XFC integrates a solar farm and local energy storage system (ESS) such that the local grid only needs to provide the power gap between the vehicle battery and the local ESS during charging events, yielding a low-cost XFC installation and higher renewable energy penetration. Two design approaches for the XFC, conductive and wireless, are based on multiphase interleaved dc-dc converter circuit, permitting flexible access to electricity. Smart fault protection mechanism is also proposed to achieve high safety during charging events. The hexagonal prism charger may be integrated into the power electronic devices with a transformer, yielding a high compactness and power density.

Abstract: Embodiments for providing file immutability for cloud storage data in a deduplicating filesystem and using a new filesystem that is spawned to receive redirected live data, after which the old filesystem is expired. Data objects are stored in the cloud by defining a protection duration from a first date to a fixed future date and a selection period to select a subset of data objects to be protected during the protection period. A retention lock is applied to the subset of data objects stored in cloud storage during the protection duration, the retention lock preventing unauthorized deletion, modification or movement of the data. A cloud bucket is created for storing the subset of data objects and a new filesystem is spawned for attachment to the cloud bucket. Upon expiration of the selection period, the retention locks are expired and the new filesystem is destroyed.

Abstract: A computer-implemented method, system and computer program product for improving accuracy of a vision model. Images of an object with a first set of perspectives are received from a dataset used to train the vision model. A three-dimensional model of the object is then generated using the images of the object from the dataset. Using the three-dimensional model of the object, images of the object with a second set of perspectives are obtained. For example, the second set of perspectives may include different perspectives than the perspectives of the object from the images contained in the dataset. The dataset used to train the vision model may then be augmented with such images of the object with a second set of perspectives. In this manner, the dataset used to train the vision model includes a greater number of perspectives of the object thereby improving the accuracy of the vision model.
