Abstract: An information handling system detects whether a text element in a graphical user interface is truncated by comparing the text element with an expected text element using a pattern-matching algorithm. The system also detects whether a non-text element in the graphical user interface is truncated by comparing the non-text element to a reconstructed copy of the non-text element.

Abstract: The components and methods disclosed herein are directed to positive type photosensitive resin compositions, which are comprised of an alkynyl containing polymer, a benzophenone type DNQ, and solvents. The alkynyl containing polymer is prepared by the condensation reaction of alkynyl containing dianhydrides and hydroxyl containing diamines, and alkynyl containing end cappers. The advantage of this formulation is that the resulting photosensitive resin composition is comprised of only a polymer, a benzophenone type DNQ PAC, and solvents that generates high resolution patterned films with good thermal and physical properties without using additional additives. This composition also enables film curing at relatively low temperatures without additional additives, simplifying the composition. After curing, the alkynyl units in the polymer chain and the chain ends give the cured film excellent solvent resistance and film retention due to intra and/or inter-molecular crosslinking.

Abstract: The present disclosure provides a method and system for efficiently and securely managing human motion data. In one aspect, a human-motion-data-managing system first receives a sequence of video images including a first person. Next, for each image in the sequence of video images, the human-motion-data-managing system detects the first person in the video image; and subsequently extracts a skeleton figure of the detected first person from the image, wherein the skeleton figure is composed of a set of human keypoints. Next, human-motion-data-managing system combines a sequence of extracted skeleton figures of the detected first person from the sequence of video images to form a skeleton sequence of the detected first person which depicts a continuous motion of the first person. The human-motion-data-managing system subsequently transmits the skeleton sequence to a server in place of the actual images of the first person to preserve the privacy of the first person.

Abstract: In various examples, a hazard detection system fuses outputs from multiple sensors over time to determine a probability that a stationary object or hazard exists at a location. The system may then use sensor data to calculate a detection bounding shape for detected objects and, using the bounding shape, may generate a set of particles, each including a confidence value that an object exists at a corresponding location. The system may then capture additional sensor data by one or more sensors of the ego-machine that are different from those used to capture the first sensor data. To improve the accuracy of the confidences of the particles, the system may determine a correspondence between the first sensor data and the additional sensor data (e.g., depth sensor data), which may be used to filter out a portion of the particles and improve the depth predictions corresponding to the object.

Abstract: An information handling system includes a storage and a processor. The storage stores a key file in a partition of the storage. The processor receives a request for the key file and determines whether the key file is located within the partition of the storage. In response to the key file not being within the partition of the storage, the processor retrieves metadata for the key file. The processor determines a physical location for the key file based on the metadata. Based on the physical location, the processor retrieves segments of the key file from the partition of the storage. The processor downloads segments of the key file from a backend server. The processor re-creates the key file based on the segments of the key file retrieved from the partition of the storage and on the segments of the key file downloaded from the backend server.

Abstract: A method for migrating virtual machine snapshots to application container platforms is disclosed. In one embodiment, such a method includes migrating, from a virtual machine platform to a volume on a container platform, a base disk file associated with a virtual machine. The base disk file has one or more delta disk files associated therewith, where each delta disk file records changes made to the virtual machine after a snapshot was taken. After migrating the base disk file, the method repeatedly performs the following for each delta disk file: takes a snapshot of the volume on the container platform; migrates the delta disk file from the virtual machine platform to the container platform; and writes the delta disk file to the volume. In certain embodiments, the delta disk files are written to the volume in an order in which they were created on the virtual machine.
