Abstract: Shared translation page tables are used for ownership transfer between software components having different execution privilege levels in a layered design. Each page table entry in a page table for the last translation level can include an ownership indicator to indicate the ownership of a physical page being mapped by the given page table entry by one or more software components. A single page table walk of the shared translation page tables can be performed to change the ownership of the physical page from one software component to another software component by updating the ownership indicator in a page table entry corresponding to that physical page.

Abstract: A hypervisor comprising a plurality of emulation routines is launched at a host. Individual emulation routines are used to perform respective tasks by a hypervisor on behalf of guest virtual machines of the host. A guest virtual machine initiates an operation which requires access to a virtual address. Subsequent to a determination by a memory management unit of the host that a virtual-to-physical address translation mapping for the virtual address which permits the operation initiated by the guest virtual machine is not available, a task is performed using a particular emulation routine, without initiating an analysis using the virtual address at the hypervisor to select the particular emulation routine from the plurality of emulation routines.

Abstract: Systems and methods are provided for generating a first model of a network based on a definition of the network, wherein the definition is used to deploy the network; generating a second model of the network based on a current deployment of the network; comparing the first model of the network and the second model of the network; and based on results of comparing the first model of the network and the second model of the network, generating output representing a discrepancy between the definition of the network and the current deployment of the network.

Abstract: This disclosure proposes systems and methods for processing natural language inputs using data associated with multiple language recognition contexts (LRC). A system using multiple LRCs can receive input data from a device, identify a first identifier associated with the device, and further identify second identifiers associated with the first identifier and representing candidate users of the device. The system can access language processing data used for natural language processing for the LRCs corresponding to each of the first and second identifiers, and process the input data using the language processing data at one or more stages of automatic speech recognition, natural language understanding, entity resolution, and/or command execution. User recognition can reduce the number of candidate users, and thus the amount of data used to process the input data. Dynamic arbitration can select from between competing hypotheses representing the first identifier and a second identifier, respectively.

Abstract: Systems and methods are disclosed for automated loading and packing for custom-sized packages. In one embodiment, an example system may include a first custom-sized package generation machine configured to generate packaging having a first range of dimensions, a second custom-sized package generation machine configured to generate packaging having a second range of dimensions, and a first independent transport robot configured to transport items to at least one of the first and second custom-sized box generation machines. The first custom-sized package generation machine and second first custom-sized package generation machine are decoupled from an item induction portion of the system.

Abstract: A content management system is provided. The content management system (CMS) uses a unique content modeling architecture using nested, reusable data entities, as well as a method for constructing a system around those entities to enable features and automation within the CMS. The solution's novelty lies in (1) a mechanism for efficiently and robustly governing, triggering, and enabling complex processes (e.g., translation workflows, publication workflows) for content within a CMS by dynamically associating system models with the content, and (2) enabling schema consistency and the creation of flexibly typed content via “model set” entities that aggregate one or more reusable content schemas.

Abstract: Systems and methods for performing malware scanning for a service provider network are disclosed. In response to accessing one or more files, file attributes may be determined. Confidence values may be generated based on the file attributes and may be used to select a scan operation. Such scan operations may include a scan operation using a 3rd party malware scan algorithm or a scan operation using a machine learning generated model. The selection of the scan operation may be performed based on a deferral learning model.

Abstract: Systems and methods are disclosed for forced air package redirection for improved fill rates. In one embodiment, an example sortation system may include a diverter configured to guide packages into a container, a first air delivery device configured to direct air at the package, a sensor configured to image the container, and a controller configured to determine, using the sensor, a position for a first package to be positioned in the container, determine the first package is adjacent to the first air delivery device, and cause the first air delivery device to be actuated, such that the air is directed at the first package. The air impacts the first package and causes the first package to change a direction or trajectory of movement of the first package.

Abstract: Devices and techniques are generally described for guided navigation into geofences. In various examples, a GUI of an application executing on a mobile device may display a first geofence surrounding a first delivery or pickup location. A reported location of the mobile device may be displayed on the GUI. A first navigation direction indicating a direction in which to walk to enter the first geofence may be determined. A first directional indicator may be displayed on the GUI indicating the first navigation direction. A determination may be made that the mobile device has entered the first geofence. First confirmation data indicating that a delivery to the first delivery address has been completed may be generated by the mobile device based at least in part on the mobile device having entered the first geofence.

Abstract: A media playback system may include features for mitigating interference. The media playback system may include a display device such as a smart TV that wirelessly transmits audio data to one or more listening devices such as earbuds, headphones, etc. The media playback system may include a remote control that can communicate using the same or similar frequencies and/or channels used for transmitting audio data. The media playback system may therefore use the radio(s) of the remote control to measure interference as a position removed from the smart TV and potentially closer to the listening device. This measurement may better reflect the listening device's ability to receive data packets reliably than a measurement of interference taken only at the location of the smart TV.

The computing device generates a simulated representation of the simulated robotic manipulator based at least in part on set of components and generated information. The computing device provides, for presentation via a display portion of the robotic design user interface, the simulated representation of the simulated robotic manipulator.

Abstract: Techniques for customer-initiated virtual machine resource allocation sharing are described. A hardware virtualization service of a cloud provider network receives a request to launch a first virtual machine, wherein the first virtual machine is of a first virtual machine type, the first virtual machine type having a resource amount allocated to virtual machines of the first virtual machine type. The hardware virtualization service causes a launch of the first virtual machine on a host computer system of the cloud provider network. The host computer system shares an allocation of the resource amount from a corresponding resource of the host computer system between the first virtual machine and a second virtual machine, wherein the second virtual machine is of the first virtual machine type.

Abstract: Systems and methods for robotic re-stowing of relocated inventory are described. In some examples, a determination may be made that a first tote located in a first zone of a processing facility includes a first item bound for a second zone of the processing facility. The first tote may be scanned by a first scanner of a first conveyance system to determine that the first tote is bound for the second zone. The first conveyance system may transport the first tote from the first zone to the second zone. The first tote may be robotically stowed on a first storage pod in the second zone. A first laden robotic drive unit may transport the first storage pod to a first pick station in the second zone.

Abstract: Systems and methods are disclosed for automated problem solve workflows for shuttle rail systems and related container movement devices. In one embodiment, an example system may include a shuttle and a controller. The controller may be configured to determine that the shuttle has a first item onboard, where the shuttle is configured to deliver the first item to a first location, determine that the first item was not delivered to the first location, and cause the shuttle to be routed to a problem solve station. The controller may be configured to determine a first container at which the shuttle is to unload the first item at the problem solve station, and cause the shuttle to unload the first item at the first container.

Abstract: A resource request is received by a peripheral device from host processing logic. The resource request includes a requested resource size. The peripheral device allocates resource of the peripheral device in response to the resource request. A resource response is sent by the peripheral device to the host processing logic. The resource response includes information indicating a location of the allocated resource.

Abstract: A system configured to improve encryption architecture for camera video data. By using an unbalanced binary tree architecture, the system enables group encryption that prioritizes a constrained device (e.g., embedded camera device), thereby reducing an amount of processing required for the constrained device to encrypt video data. For example, placing the constrained device near the root of the unbalanced binary tree offloads processing from the constrained device to other group members. At each device operating as a member of the group, a privacy enforcement policy operates to authorize/authenticate messages, using time-sensitive encryption keys that enable refined control over decrypted content. In some examples, the architecture can enable end-to-end encryption by removing any cloud services from the group. Alternatively, the architecture can include a cloud service with high or low privileges, enabling refined control over decrypted content while providing additional functionality.

Abstract: A method for modifying recorded audio of a video title may include: identifying a video title available for presentation; identifying a portion of audio data, of the video title, representing dialogue of an actor of the video title; identifying a first utterance of the dialogue to be replaced in the video title; selecting, based on a replaceable amount of the audio data, a second utterance to replace the utterance word in the portion of the audio data; generating, based on a voice profile of the actor, first speech signals representing the actor uttering the second utterance; removing second speech signals representing the actor uttering the first utterance from the dialogue; adding the first speech signals into the dialogue using at least a portion of the replaceable amount; and generating a modified version of the video title comprising the dialogue with the speech signals added.

Abstract: Speech processing tasks may be allocated at least partly to a local device (e.g., user computing device that receives spoken words) and at least partly to a remote device to determine one or more user commands or tasks to be performed by the local device. The remote device may be used to process speech that the local device could not process or understand, or for other reasons, such as for error checking. The local device may then execute or begin to execute locally determined tasks to reduce user-perceived latency. Meanwhile, the entire media input, or a portion thereof, may be sent to the remote device to process speech, verify the tasks and/or identify other user commands in the media input (or portion thereof).
