  • Publication number: 20240089078
    Abstract: A method performed by a first network device comprises reaching a synchronization state with a first communication device based on alignment information of a first interface of the first network device. The alignment information of the first interface includes at least one of a line rate order for line rate iteration, an iteration time interval and an iteration start time. The method further comprises determining whether a second network device has reached the synchronization state with a second communication device at a same line rate as the first interface, wherein the second network device includes a second interface, and the second network device tries to reach the synchronization state with the second communication device based on the same alignment information as the first interface of the first network device. The method further comprises locking the same line rate at the first interface of the first network device.

  • Publication number: 20240084239
    Abstract: Embodiments of the present disclosure may teach a counting assembly, a counting device, and applications thereof. The counting assembly may include a main body. The main body may be provided with a concave sample tank, a bottom end of a sample tank being plane. A cross-sectional area of the sample tank may gradually increase from the bottom end to a top end of the sample tank. By using the counting assembly, obtaining a count of particles or cells, etc. of the sample in the sample tank may be realized by imaging the sample for one or more times, which makes the process fast and efficient, as well as minimizing the counting error generated by an uneven distribution of the particles or cells and/or a limited sampling of the particles or cells, etc.

  • Publication number: 20240070044
    Abstract: Systems, devices, media, and methods are presented for releasing an application feature in incremental stages while monitoring the application for anomalies. The feature includes a package of code and an action setting. The methods in some implementations include identifying active devices on which the application has been installed, monitoring the application according to a set of metrics, activating the feature by changing its action setting for a first segment of the active devices, pausing the feature if an anomaly is detected among the set of metrics, and generating a repair ticket. As long as no anomaly is detected, the activating step proceeds for subsequent segments of the active devices, iteratively, until the release is completed. A feature rank may be used to process and release a plurality of features in order of priority.

  • Patent number: 11915976
    Abstract: An ammonium fluoride gas may be used to form a protection layer for one or more interlayer dielectric layers, one or more insulating caps, and/or one or more source/drain regions of a semiconductor device during a pre-clean etch process. The protection layer can be formed through an oversupply of nitrogen trifluoride during the pre-clean etch process. The oversupply of nitrogen trifluoride causes an increased formation of ammonium fluoride, which coats the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) with a thick protection layer. The protection layer protects the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) during the pre-clean process from being etched by fluorine ions formed during the pre-clean process.

  • Patent number: 11916962
    Abstract: Disclosed are examples related to data driven interfaces for decoupling management system components from a manufacturer or a platform of client devices managed by the management system. In some examples, among others, a system can generate a data driven interface template that can be used to cause rendering of a data driven user interface for configuring a profile payload of a device profile for the client device. The system can generate, based on values associated with the data driven user interface, a profile document in an instance in which values are obtained from the data driven user interface. In some aspects, the profile document is a generic representation of the profile payloads for the platform, the manufacturer or the type of the client device.

  • Patent number: 11897490
    Abstract: Described herein are systems, methods, and non-transitory computer-readable media for isolating commercial components from a harsh vehicle operating environment to increase the longevity of such components and to decrease their failure rate. Also described herein are systems, methods, and non-transitory computer-readable media for monitoring the operational health status of vehicle components for failure, and upon detecting failure of a component, initiating a processing task reassignment and fault recovery process. In this manner, processing load handled by the component prior to failure can be offloaded to one or more other vehicle components while a fault recovery process is initiated for the component. When the failed component is operational again, the vehicle may revert back to the task assignment in place prior to the component failure, may continue with the current task assignment, or may transition to another different task reassignment.

  • Publication number: 20240045727
    Abstract: Systems, devices, media, and methods are presented for throttling (i.e., adjusting) the workload of an application (e.g., number of task requests) in order to improve processor core usage within a heterogeneous multiprocessor system. When high-performance processing is beneficial to the application, the number of task requests may be increased in order to have high-performance processor cores within the heterogeneous multiprocessor system core processor perform the tasks. On the other hand, when high-performance processing is not beneficial, the number of task requests may be decreased in order to have low-performance processor cores within the heterogeneous multiprocessor system perform the tasks. Processor core usage is monitored, and the number of tasks being performed are adjusted to match the processor core usage to a target processor core usage for functions the application is performing.
