  • Patent number: 9935896
    Abstract: According to one aspect, a method includes an Intercloud Fabric Switch (ICS) included in a public cloud and an ICS cluster obtaining a packet, and determining if the packet is obtained from a site-to-site link that links the ICS to an enterprise datacenter. If the packet is obtained from the site-to-site link, it is determined whether the packet is an unknown unicast packet. If the packet is an unknown unicast packet, the packet is dropped, and if not, the packet is provided to an access link that links the ICS to a virtual machine. If the packet is not obtained from the site-to-site link, it is determined whether the packet is obtained from an inter-ICS link that allows the ICS to communicate with the ICS cluster. If the packet is obtained from the inter-ICS link, the packet is dropped if it is an unknown unicast packet.

  • Patent number: 9934853
    Abstract: The present disclosure relates to a method and apparatus for performing a read operation of an RRAM cell, which applies a non-zero bias voltage to unselected bit-lines and select-lines to increase a read current window without damaging corresponding access transistors. In some embodiments, the method may be performed by activating a word-line coupled to a row of RRAM cells comprising a selected RRAM device by applying a first read voltage to the word-line. A second read voltage is applied to a bit-line coupled to a first electrode of the selected RRAM device. One or more non-zero bias voltages are applied to bit-lines and select-lines coupled to RRAM cells, within the row of RRAM cells, having unselected RRAM devices.

  • Patent number: 9934085
    Abstract: A detector detects, using an error code, an error in data stored in a memory. The detector determines whether the error is uncorrectable using the error code. In response to determining that the error is uncorrectable, an error handler associated with an application is invoked to handle the error in the data by recovering the data to an application-wide consistent state.

  • Patent number: 9934586
    Abstract: Various aspects of a system and a method to process multimodal images are disclosed herein. In accordance with an embodiment, the system includes an image-processing device that generates a structured point cloud, which represents edge points of an anatomical portion. The structured point cloud is generated based on shrink-wrapping of an unstructured point cloud to a boundary of the anatomical portion. Diffusion filtering is performed to dilate edge points that correspond to the structured point cloud to mutually connect the edge points on the structured point cloud. A mask is created for the anatomical portion based on the diffusion filtering.
