  • Patent number: 11657024
    Abstract: A map-reduce compatible distributed file system that consists of successive component layers that each provide the basis on which the next layer is built provides transactional read-write-update semantics with file chunk replication and huge file-create rates. Containers provide the fundamental basis for data replication, relocation, and transactional updates. A container location database allows containers to be found among all file servers, as well as defining precedence among replicas of containers to organize transactional updates of container contents. Volumes facilitate control of data placement, creation of snapshots and mirrors, and retention of a variety of control and policy information. Also addressed is the use of distributed transactions in a map-reduce system; the use of local and distributed snapshots; replication, including techniques for reconciling the divergence of replicated data after a crash; and mirroring.

  • Patent number: 11652346
    Abstract: A system and method of protecting the input components of a power supply. An input overcurrent protection module is provided, which may be implemented in firmware, which monitors the input current through an input interface of the power supply. When the input current exceeds a threshold current (i.e., a current above the maximum rating of an input component, such as an input cable), the input current protection module determines whether an input overcurrent event is occurring. When it is determined that an input overcurrent event has occurred, the input current protection module disables the output circuitry of the power supply and triggers a few timers. The input overcurrent protection module continues to monitor the input and, if the input current continues to exceed the threshold current, is configured to shut down the power supply. In this way, input components may be protected from overcurrent issues in high-power systems.

The print bar is then indexed in a second direction substantially orthogonal to the first direction before scanning the print bar back over the build platform in a third direction opposite the first direction to deposit additional liquid agent onto the layer of build powder.

  • Patent number: 11650936
    Abstract: Systems and methods are provided for binding one or more components to an identification component of a hardware module. Each of the serial numbers for the one or more components are included within a module-specific authentication certificate that is stored within the identification component of the hardware module. When connected to a computing platform, an authentication system of the computing platform is capable of retrieving the module-specific authentication certificate. The authentication system can compare the list of serial numbers included in the module-specific authentication certificate with one or more serial numbers read over a first interface. If the two lists of serial numbers match, the authentication system can flag the hardware module as authenticate through authentication of all components of the hardware module.

  • Patent number: 11650948
    Abstract: In a method for sending a server identifier to a KVM switch, a management processor of a server determines that a push button on an exterior surface of the server has been pushed. In response to determining that the push button has been pushed, the management processor generates a displayable image containing a server identifier for the server, includes the displayable image in a network message, and broadcasts the network message to a local network that includes the server and a KVM switch. In one example, the method also includes receiving the server button message at the KVM switch when the KVM switch is not switched to enable the server to control a video port of the KVM switch, and in response to receiving the server button message at the KVM switch, sending the displayable image to a monitor via the video port. Other implementations are described and claimed.

  • Patent number: 11652690
    Abstract: Examples of the present disclosure relate to updating network devices belonging to a group of network devices. In one aspect, a network controller coupled to the network devices of the group of network access devices, responsive to a first command, initiates a group update process for the network devices of the group is to update the network devices of the group sequentially according to an ordered list. Responsive to a second command during the group update process while a firmware image of a particular network device is updated, the network controller aborts the group update process for the network devices of the group. Aborting the group update process comprises removing a first subset of network devices subsequent to the particular network device in the ordered list from the ordered list such that the firmware image of the first subset of network devices will not be updated and rolling back the firmware image of the particular network device.

  • Patent number: 11652926
    Abstract: A method of digital printing is disclosed in which a digital image to be printed has at least one region having pixels comprising superpositioned layers of a first ink and a second ink. The method includes producing at least one sample print and calibrating misalignment of the superpositioned layers at a plurality of calibration locations on the sample print. The resultant misalignment data is provided to a morphing program to pre-deform the digital image to provide a modified digital image which compensates for misalignment during printing. The image is then printed using the modified digital image. An apparatus and a machinereadable storage medium comprising instructions executable by a processor are also disclosed.
