  • Publication number: 20220241520
    Abstract: The disclosed tamper-evident closure (100) encloses a medical access device, such as a vascular access device (200), such that it will be visibly apparent if the medical access device contained in the tamper-evident closure becomes exposed. The tamper-evident closure cannot be reapplied over the medical access device in a way to look the same as it did prior to exposing the medical access device. The tamper-evident closures comprise a holding cavity (110), a securing mechanism (160), and an apparent release. The disclosed tamper-evident closures are well suited for securing a medical access device that has an access point for delivering fluid to a patient or removing fluid from a patient.

  • Patent number: 11372703
    Abstract: A memory controller receives, via a first interface, a first read request requesting a requested data granule. Based on receipt of the first read request, the memory controller transmits, via a second interface, a second read request to initiate access of the requested data granule from a system memory. Based on a determination to schedule accelerated data delivery and receipt by the memory controller of a data scheduling indication that indicates a timing of future delivery of the requested data granule, the memory controller requests, prior to receipt of the requested data granule, permission to transmit the requested data granule on the system interconnect fabric. Based on receipt of the requested data granule at the indicated timing and a grant of the permission to transmit, the memory controller initiates transmission of the requested data granule on the system interconnect fabric and transmits an error indication for the requested data granule.
