Publication number: 20240055305Abstract: 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.Type: ApplicationFiled: August 12, 2022Publication date: February 15, 2024Inventors: Santosh TRIPATHI, Tuyen TRAN

Publication number: 20230060496Abstract: 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.Type: ApplicationFiled: November 10, 2022Publication date: March 2, 2023Inventors: Aleksandr Zelezniak, Minsung Jang, Kaustubh Joshi, Xuan Tuyen Tran

Publication number: 20160063184Abstract: A user device for professional workflow assistance provides decision support in the form of concise alerts in the form of immediate feedback (real-time or near real-time) analysis performed by a user device application based on locally stored rules. The decision support is rendered in a timely manner in a current session with the patient, client or customer to maintain a context of the information gathering and the concurrent consideration of the decision support provided. The decision maker need not retreat to an office or separate location for consideration and analysis of the decision support results, but instead immediately considers the application generated results on the rendering screen of the user device.Type: ApplicationFiled: September 2, 2014Publication date: March 3, 2016Inventors: Stephen S.

Publication number: 20160012030Abstract: A data entry form rendered on a screen display is based on a user provided form such that the appearance and field positions of the screen display simulates the paper form that is familiar to the user. The rendered form identifies field positions based on a scan of the paper form, and a Graphical User Interface receives user input for attributes for each identified field. Fields are mapped to metadata for specifying the attributes, such as data type, ranges, and manner of entry. Subsequent data entry based on the generated form provides a user experience similar to the corresponding paper form for mitigating any change in workflow or thought process based on the form. In this manner, a repeatable processes which can be reduced to templated data entry may be transformed to electronic forms without deviating from the visual cues afforded by the paper forms that the office staff and professionals have become accustomed to.Type: ApplicationFiled: July 8, 2014Publication date: January 14, 2016Inventors: Tuyen Tran, Matthew O'Neill, Stephen S.
