  • Publication number: 20240055305
    Abstract: Embodiments described herein may be related to apparatuses, processes, systems, and/or techniques for analyzing a wafer for defects using cross-section analysis by applying a sacrificial layer on a surface of the wafer prior to forming a cavity into the wafer for analysis. In embodiments, an epoxy material may be placed into the cavity after analysis, and a capping layer placed on top of the epoxy material. The sacrificial layer, which may contain dislodged particles or debris from the formation of the cavity on its surface, is then removed, providing a clean surface on the wafer. The wafer may then be reintroduced into the manufacturing line for further processing. Other embodiments may be described and/or claimed.

  • Publication number: 20230060496
    Abstract: The disclosed technology is directed towards associating a distributed unit (a baseband function) with a radio unit, corresponding to a service area, when the radio unit transitions from an idle state to an active state with respect to serving user equipment. When an idle radio unit receives a message requesting connection from a formerly idle user equipment, or user equipment to be served due to a handover, the message triggers assignment of a distributed unit to the radio unit, whereby the radio unit becomes active to serve the user equipment. If insufficient distributed unit capacity exists, a new distributed unit is dynamically instantiated and assigned to the radio unit. When a radio unit transitions from active to idle, the radio unit is disassociated from the distributed unit. If a distributed unit is not associated with any radio unit, the distributed unit is deactivated to reduce resource consumption.

  • Patent number: 9298757
    Abstract: A computer-implemented system for searching includes a data store accessible via a network for storing a data set; an indexing system coupled to the network and indexing the data set, the indexing system configured to generate content vectors for terms in the data set; generate index vectors for terms in the data set; and generate a bitset signature from the index vector. The system further includes a search module coupled to the network and configured to receive a search query and perform a search on one or more terms in the search query by accessing a bitset signature and content vector corresponding to the term; retrieving bitset signatures that are within a predetermined closeness to the bitset signature; selecting content vectors corresponding to retrieved bitset signatures; and selecting content vectors that are within a predetermined similarity to the term content vector; and return the terms corresponding to the content vectors.
