  • Publication number: 20250250527
    Abstract: Disclosed is a system and method for sealing an opening through the boundary of a controlled thermal and gaseous environment such as an incubator or refrigerator, where conduit channels of arbitrary size and number are transferred across the boundary. A silicone or polymeric tube with flanges at either end is passed through the boundary opening, fixing one side to the boundary wall and attaching the other to a mechanism that controls or constrains the rotation of the tube. This is achieved by rotating or twisting one end of the tube, creating a hyperboloid-like structure that will seal around the conduits and thereby seal the opening. To further improve thermal efficiency, insulating material such as expanded polystyrene beads are placed into the space between the silicone or polymeric tube and the wall of the incubator, providing thermal stability that cannot be achieved by conventional conduit transferring methods.

  • Patent number: 12208229
    Abstract: Disclosed is a convenient joining of tubing in a secure, leak-free connection, suitable for aseptic fluid transfer, wherein two holders each have a channel designed to house tubing and each holder has a mating surface at one end of the channel. The ends of the respective tubing closest to the mating surfaces are fitted with male and female hollow connectors. Tape is attached to the region of the connectors near the tubing and/or to the tubing itself. After the holders are joined, the ends of the tape are pulled to advance the male and female connectors to mate and form a secure connection.

  • Patent number: 12116562
    Abstract: Disclosed is a system for automating passaging of anchorage dependent or adherent mammalian cells, having a fluid distribution cartridge where fluid channels each has an associated pneumatically controlled valve, and the valves can be selectively opened and closed to allow fluid which is pumped into channels in the cartridge to be selectively passed or interrupted. The channels are connected with a series of vessels each held in a housing structure, and a first frame rests on a surface and a second frame is attached with the first frame such that the second frame can tilt on a first axis with respect to the first frame, and the housing is attached to the second frame such that the housing can tilt on a second axis with respect to the second frame, and wherein the second axis is orthogonal to the first axis.

  • Publication number: 20240168890
    Abstract: A processor package comprises a caching agent that is operable to respond to a first sequence of direct-to-cache (DTC) write misses to a partition in a set in a cache by writing data from those write misses to the partition. When the partition comprises W ways, the caching agent is operable to write data from those write misses to all W ways in the partition. After writing data from those write misses to the partition, and before any data from the partition in the set has been read, the caching agent is operable to receive a second sequence of DTC write misses to the partition, and in response, complete those write misses while retaining the data from the first sequence in at least W-1 of the ways in the partition. Other embodiments are described and claimed.

  • Publication number: 20240160568
    Abstract: Examples include techniques associated with data movement to a cache in a disaggregated die system. Examples include circuitry at a first die receiving and granting requests to move data to a first cache resident on the first die or to a second cache resident on a second die that also includes a core of a processor. The granting of the request based, at least in part, on a traffic source type associated with a source of the request.

  • Publication number: 20240160570
    Abstract: Mechanisms to identify key sections of input-output (IO) packets and use for efficient IO caching and associated apparatus and methods. Data, such as packets, are received from an IO device coupled to an IO port on a processor including a cache domain including multiple caches, such as L1/L2 and L3 or Last Level Cache (LLC). The data are logically partitioned into cache lines and embedded logic on the processor is used to identify one or more important cache lines using a cache importance pattern. Cache lines that are identified as important are written to a cache or a first cache level, while unimportant cache lines are written to memory or a second cache level that is higher than the first cache level. Software running on one or more processor cores may be used to program cache importance patterns for one or more data types or transaction types.
