  • Patent number: 10936497
    Abstract: In general, embodiments of the technology relate to a method and system for storing and reading data from persistent storage. More specifically, embodiments of the technology relate to a method and system for storing data in persistent storage, where the data written to the persistent storage is not immediately accessible in the persistent storage (i.e., during the inaccessibility period). In such instances, embodiments of the technology provide a method and system to enable the storage system to service read requests for the data using a primary cache entry table (PCET) and an overflow table.

  • Patent number: 10007443
    Abstract: One or more virtual functions is exposed via a shared communication interface. A plurality of I/O buffers shared across said virtual functions are provided. For each of said one or more virtual functions, a corresponding submission queue comprising one or more virtual submission queue entries (SQEs) is used, wherein a memory access device is configured to: receive data pushed to the memory access device by a client host system, store the data in an allocated one of the I/O buffers, receive a submission queue entry (SQE) that invokes one of said virtual functions with respect to the data, and use a corresponding one of the plurality of logic circuits that is associated with the invoked virtual function to perform the virtual function with respect to the data as stored in the allocated I/O buffer.

  • Patent number: 10002087
    Abstract: A request is received via a message submission queue. The request is sent from a core associated with an external processor coupled by a communication interface. The message submission queue is associated with a memory access engine circuit configured to perform one or more memory access functions. The memory access engine circuit is used to dequeuer a next message from its corresponding message submission queue. The memory access engine circuit is used to perform a message function invoked by the message. The memory access engine circuit is used to receive a result of performing the message function. The memory access engine circuit is used to prepare and send to an external processing core that sent the message a response message determined based at least in part on the result.

  • Patent number: 9988161
    Abstract: In a method of loading checked luggage on unit load devices corresponding to an aircraft having a passenger compartment, each piece of checked luggage is associated with a unique identifier. Each piece of checked luggage is weighed and its weight is associated with its corresponding unique identifier. A best possible luggage placement is calculated considering a distribution of passenger weight, thereby allowing the passengers to sit at their preferred location rather than by pre-allocation. A desired placement of the checked luggage is calculated based on the weight of each piece of checked luggage, the acceptable distribution of weight in the passenger compartment and overall fuel state over mission profile.

  • Patent number: 9642814
    Abstract: Inside-out gelation process to generate hydrogel microcapsules (aka microbeads). Methods of encapsulating biological material in the microbead 3-dimensional hydrogel matrix are described herein. The process generally comprises formation of a mixture of a hydrogel precursor compound, an optional biological material, and a divalent cation. The mixture is then combined with alginate, to generate an alginate shell around droplets of the mixture, followed by gelation of the hydrogel precursor core, and removal of the temporary alginate shell to yield self-sustaining microbeads.
