  • Patent number: 10987513
    Abstract: This document discusses, among other things, systems and methods for robotically assisted implantation of an implant in a patient. A system includes an external positioning unit configured to engage an elongate member of the implant, and a control console communicatively coupled to the external positioning unit. The control console may have a user interface that enables a user to input motion control instructions. The control console may generate a motion control signal, according to a specific motion control instruction, to control the external positioning unit to propel the implant into a target implant site. The system may be used to robotically control the delivery and positing of a cochlear implant during a hearing-preservation cochlear implant surgery.

  • Publication number: 20200059311
    Abstract: A system on a chip (SOC) is configured to support multiple time domains within a time-sensitive networking (TSN) environment. TSN extends Ethernet networks to support a deterministic and high-availability communication on Layer 2 (data link layer of open system interconnect “OSI” model) for time coordinated capabilities such as industrial automation and control applications. Processors in a system may have an application time domain separate from the communication time domain. In addition, each type time domain may also have multiple potential time masters to drive synchronization for fault tolerance. The SoC supports multiple time domains driven by different time masters and graceful time master switching. Timing masters may be switched at run-time in case of a failure in the system. Software drives the SoC to establish communication paths through a sync router to facilitate communication between time providers and time consumers. Multiple time sources are supported.
