  • Publication number: 20220325937
    Abstract: Supercooled water or solutions can be destabilized by the nucleation of ice, which can be triggered by a wide range of different mechanisms. Constraining water in a constant-volume (isochoric) container minimizes the effects of many of these mechanisms through thermodynamic, kinetic, and fluid dynamic means, significantly enhancing supercooling stability. This invention describes methods and devices for high-stability and optionally transportable supercooling of aqueous solutions or suspensions, and the stable and long-term preservation of biological matter that may be stored therein.

  • 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: 11379123
    Abstract: One or more memory systems, architectural structures, and/or methods of storing information in memory devices is disclosed to improve the data bandwidth and or to reduce the load on the communications links in a memory system. The system may include one or more memory devices, one or more memory control circuits and one or more data buffer circuits. In one embodiment, the Host only transmits data over its communications link with the data buffer circuit. In one aspect, the memory control circuit does not send a control signal to the data buffer circuits. In one aspect, the memory control circuit and the data buffer circuits each maintain a separate state machine-driven address pointer or local address sequencer, which contains the same tags in the same sequence. In another aspect, a resynchronization method is disclosed.

  • 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.
