  • Publication number: 20240112953
    Abstract: A microelectronic device including a galvanic isolator with filler metal within an upper isolation element. The galvanic isolator includes a lower isolation element, an upper isolation element, and an inorganic dielectric plateau between the lower isolation element and the upper isolation element. The upper isolation element contains tines of filler metal which are electrically tied to each other and are electrically tied to the upper isolation element. The ends of the tines are rounded to minimize electric fields. The filler metal increases the overall metal density on the metal layer of the upper isolation element to meet the typical metal density requirements of modern microelectronic fabrication processing.

  • Patent number: 11944289
    Abstract: Articulating surgical instruments are disclosed. In one embodiment, a surgical instrument may include an elongated shaft assembly including an articulable portion moveable between a non-articulated configuration and an articulated configuration. First and second articulating shafts of the elongated shaft assembly may be coaxially arranged and axially fixed at an attachment point located distally from the articulable portion. Proximal portions of the first and second articulating shafts may be displaceable in opposing directions to articulate the articulable portion from the non-articulated configuration to the articulated configuration. In another embodiment, an articulation control may be movable from a first position to a second position to move an articulation lock from a locked configuration to an unlocked configuration to selectively permit articulation of a surgical instrument. The articulation lock also may be movable from the second position to a third position to articulate the surgical instrument.

  • Publication number: 20200225966
    Abstract: A trained cross-functional process model and a subject-specific virtual assistant provide service professionals access to a body of knowledge that could understand their specific needs, automate service tasks, and provide them service information when they need it. By embedding artificial intelligence in the service context, the techniques in this disclosure support low cost inputs that allow novice service professionals and artificial intelligence to replace the services of a journeyman, particularly in service contexts where service quality and/or human judgement is irrelevant or only marginally relevant. The systems and methods herein may, in some implementations, benefit stakeholders, owners, and/or equity holders in many service contexts.

  • Patent number: 10338837
    Abstract: This disclosure relates to allocating memory resources of a computing device comprising non-volatile random access memory (NVRAM) and dynamic random access memory (DRAM). An exemplary method is performed for every independently executable component of an application and includes determining attributes of the component. The method also includes associating the component with a memory profile of a plurality of memory profiles based on the attributes, wherein each memory profile of the plurality of memory profiles specifies a number of banks of the NVRAM and a number of banks of the DRAM. The method also includes causing the computing device to generate an assignment of the component to banks of the NVRAM and DRAM based on the memory profile associated with the component so the computing device can execute the component using the banks of the NVRAM and DRAM based on the assignment.

  • Patent number: 10114585
    Abstract: Various aspects are described herein. In some aspects, the present disclosure provides a method of communicating data between an electronic unit of a system-on-chip (SoC) and a dynamic random access memory (DRAM). The method includes initiating a memory transaction corresponding to first data. The method includes determining a non-unique first signature and a unique second signature associated with the first data based on content of the first data. The method includes determining if the non-unique first signature is stored in at least one of a local buffer on the SoC separate from the DRAM or the DRAM. The method includes determining if the unique second signature is stored in at least one of the local buffer or the DRAM based on determining the non-unique first signature is stored. The method includes eliminating the memory transaction with respect to the DRAM based on determining the unique second signature is stored.
