Abstract: A computer implemented method includes receiving multiple channels of audio from three or more microphones detecting speech from a meeting of multiple users, localizing speech sources to determine an approximate direction of arrival of speech from a user, using a speech unmixing model to select two channels corresponding to a primary and a secondary microphone, and sending the two selected channels to a meeting server for generation of a speaker attributed meeting transcript.

Abstract: It is recognized herein that existing approaches to M2M/IoT networks do not realize Network Functions Virtualization (NFV). In particular, existing M2M service layers (e.g. oneM2M) are not built, managed, or operated in accordance with NFV practices. In an example embodiment, an M2M apparatus assigns various roles to various common service entities, such that common service functions can be pooled together with one another. The roles can be migrated among common service entities to ensure that the pools are managed and controlled efficiently. Further, pool members can exit and join one or more pools.

The present disclosure further relates to a method for preparing a quantum dot light-emitting diode, and an array substrate and a display device including the quantum dot light-emitting diode.

Abstract: A system and method include reception of a first plurality of audio signals, generation of a second plurality of beamformed audio signals based on the first plurality of audio signals, each of the second plurality of beamformed audio signals associated with a respective one of a second plurality of beamformer directions, generation of a first TF mask for a first output channel based on the first plurality of audio signals, determination of a first beamformer direction associated with a first target sound source based on the first TF mask, generation of first features based on the first beamformer direction and the first plurality of audio signals, determination of a second TF mask based on the first features, and application of the second TF mask to one of the second plurality of beamformed audio signals associated with the first beamformer direction.

Abstract: Enhancements to the device management functionality within service layer architecture of a Gateway node are described. The SL application registration procedure can be enhanced for devices in support of device management. Functionality can be added to the service layer to initiate automated request notification for DM purposes. Lightweight SL Transport Protocol bindings can support sending multiple DM commands called DM Action Scripts with a specific focus on the Constrained Application Protocol (CoAP) Protocol.

Abstract: Multicast messaging may be managed in a machine-to-machine/Internet of things context, such as a CoAP network, via the inclusion of server selection criterion in multicast request messages and/or resource directory registration management. Server selection criteria may be explicit or implicit. An explicit criterion may be expressed, for example, as an IP address, a server identifier relative to a group context, or a Bloom filter. An implicit criterion may, for example, relate to the context of the request or the requestor, and include such information as data accuracy, data type, application, operating system, network location, geolocation, resource creation time, and resource update time. Server selection criteria may be maintained by a resource directory and/or via a user interface.

Abstract: Current discovery mechanisms lack capabilities, such as capabilities related to permissions associated with a given registrant for example. In an example embodiment, a registrant of a service layer can communicate with a network node that hosts the service layer. The network node may receive a discovery request for a resource from the registrant. The discovery may request include various context. For example, the context of the discovery request may be indicative of an operation that the registrant intends to perform on the resource, a role that the registrant intends to assume if the registrant accesses the resource, a location in which the registrant intends to access the resource, or a subscription plan that the registrant intends to use if the registrant accesses the resource. Based on the context of the discovery request, the network node may determine whether one or more resources at the service layer satisfy the discovery request.

Abstract: Systems and methods for a graphical display that is configured to deliver an augmented visual representation of the media data and the knowledge landscape map data are provided. The learning platform includes a control module embodied in program code which is configured to update or manipulate the displayed media data and n-dimensional knowledge landscape map data so that the same learning or knowledge topic is identified, played or otherwise presented to the user. Users can navigate through multiple dimensions via additional graphical controls.

Abstract: Existing approaches to security within network, for instance oneM2M networks, are limited. For example, content might only be protected while the content is in transit between entities that trust each other. Here, the integrity and the confidentiality of content in an M2M network are protected. Such content may be “at rest,” such that the content is stored at a hosting node. Only authorized entities may store and retrieve the data that is stored at the hosting node, and the data may be protected from a confidentiality perspective and an integrity perspective.

Abstract: A computer implemented method includes receiving audio signals representative of speech via multiple audio channels transmitted from corresponding multiple distributed devices, designating one of the audio channels as a reference channel, and for each of the remaining audio channels, determine a difference in time from the reference channel, and correcting each remaining audio channel by compensating for the corresponding difference in time from the reference channel.

Abstract: A Data Producer may be configured to negotiate and initiate a Data Continuity service with an M2M/IoT system. This service may be for specific data sets or all data sets generated by the Data Producer. The M2M/IoT system may be configured to autonomously decide to start a Data Continuity Service for a data set of a Data Producer. The Data Producer may interact directly with an Aggregator SL to store its aggregated data set, and may also be configured to update and delete entries in this data set and start a data service on this aggregated data set. A Local SL may be configured to manage all interactions with an Aggregator SL, and the Local SL may be configured to retarget requests from the Data Producer to the Aggregator SL, including a request to start a data service on the aggregated data set.

In an example, a cloud based DNS-SD server is separate from the regular Internet DNS servers. This cloud DNS-SD server may run as a private Infrastructure as a Service (IaaS) specifically for service discovery in the virtual discovery zone.

Abstract: A left atrial appendage occluder (200) comprises a sealing part (220), a fixing part (210) disposed at one side of the sealing part (220), and a connection part (230) for connecting the sealing part (220) and the fixing part (210). The radial deformation capacity of the sealing part (220) is greater than the radial deformation capacity of the fixing part (210), and/or, the axial deformation capacity of the sealing part (220) is greater than the axial deformation capacity of the fixing part (210). In the left atrial appendage occluder (200), the radial or axial deformation capacity of the sealing part (220) is configured to be greater than the radial or axial deformation capacity of the fixing part (210), thereby avoiding the situation in which the sealing part (220) is not optimally fitted with the opening of the left atrial appendage (10) when the fixing part (210) is placed inside of the left atrial appendage (10), which in turn enhances the occlusion effect.

Abstract: Some services offered by M2M service layers will have contact information that will be used in order to interact with applications. For example, a service layer may need to send notification messages to an application. To do this, the service layer relies on stored contact information to know how to reach the application. If the device hosting the application moves and the application changes its contact information, then the contact information that is in the service layer is stale. As a result, these services will be inefficient, or in some cases, fail altogether. Embodiments described herein provide systems and methods to enable mechanisms to update stale contact information in M2M service layers.
