  • Patent number: 12237364
    Abstract: A display device includes: a first sub-pixel having a first emission area and a first sub-area adjacent to each other in a first direction; and a bank extending around a portion of the first emission area and the first sub-area. The bank includes: a first wall extending around the first sub-area; and a second wall adjacent to the first emission area in a second direction crossing the first direction. The second wall and the first wall are spaced apart from each other in the first direction.

  • Publication number: 20250033535
    Abstract: A lower rail for a seat of a vehicle has a structure with a curved movement path, in which the seat may be moved in an oblique direction or a diagonal direction according to various seat positions, thereby allowing a degree of freedom for adjusting a seat position movement. In addition, the lower rail includes a curved inner channel bent at a predetermined angle and a curved outer channel bent at about a same angle as the curved inner channel, which are separately provided and configured to be mutually combined in order to provide one curved movement path for moving the seat.

  • Publication number: 20240169207
    Abstract: Methods, systems, and computer-readable storage media for receiving a set of crash reports, determining a set of trace vectors by processing a set of stack traces through a first DL model, each trace vector in the set of trace vectors being a multi-dimensional vector representation of a stack trace of a respective crash report provided from the set of stack traces, generating a set of feature vectors by processing the set of trace vectors through a second DL model, each feature vector being a multi-dimensional vector representation of a stack trace of a respective crash report, and clustering each crash report in the set of crash reports into a group of a set of groups based on comparing feature vectors of respective crash reports, each group representative of a root cause resulting in respective crashes of the software system represented in one or more crash reports.

  • Publication number: 20220108191
    Abstract: In an example embodiment, a machine learned model is utilized for identifying duplicate crash dumps. After a developer submits code, corresponding test cases are used to ensure the quality of the software delivery. Test failures can occur during this period, such as crashes, errors, and timeouts. Since it takes time for developers to resolve them, many duplicate failures can occur during this time period. In some embodiments, trash triggering is the most time-consuming task of development, and thus if duplicate crash failures can be automatically identified, the degree of automation will be significantly enhanced. To locate such duplicates, a training-based machine learned model uses component information of an in-memory database system to achieve better crash similarity comparison.
