Abstract: A foldable display screen includes a display panel, a first optical adhesive layer, a first cover protection layer, a second optical adhesive layer, and a second cover protection layer; the first optical adhesive layer is located on the display panel; the first cover protection layer is located on a side of the first optical adhesive layer away from the display panel; the second optical adhesive layer is located on a side of the first cover protection layer away from the first optical adhesive layer; the second cover protection layer is located on a side of the second optical adhesive layer away from the first cover protection layer. At an operating temperature, an elastic modulus of the second optical adhesive layer is smaller than an elastic modulus of the first optical adhesive layer.

Abstract: An axial motor includes a fastening plate and a plurality of magnetic cores. The plurality of magnetic cores are spaced apart around the inner shaft sleeve. A magnetic core end part of the magnetic core covers a part of an end surface of a magnetic core winding part of the magnetic core, and an end surface, of the magnetic core winding part, that is not covered by the magnetic core end part forms a step surface. The fastening plate is fastened to an end surface of the inner shaft sleeve. The fastening plate includes an accommodating groove that is concave relative to the end surface of the inner shaft sleeve. A plurality of magnetic core accommodating holes are provided in the accommodating groove. The plurality of magnetic core accommodating holes respectively correspond to magnetic core end parts that accommodate the plurality of magnetic cores.

Abstract: An example operation may include one or more of receiving a message from an agent installed at a data replication server, the message comprising a status identifier of a checksum validation of a data replication operation, identifying a latency value associated with the data replication server, determining whether a data loss has occurred based on the status identifier of the checksum validation and the latency value, and in response to a determination that the data loss has occurred, transmitting a notification of the data loss to a computing system associated with the data replication server.

Abstract: The present invention relates to the field of architecture of Internet of Things, specifically to a semantics-based architectural model of Internet of Things. The present invention puts forward the architecture of the Internet of Things based on the study of semantic Web, sensor network, sensor Web, wherein the architecture is divided into 7 layers: physical layer, perception layer, gateway layer, data layer, semantic layer, service layer and application layer. By means of semantic processing of sensor data and building of sensor ontology, the architecture is capable of realizing automatic discovery of heterogeneous resources, enhancing the expression ability of data, achieving effective sharing, reuse, integration, and access to data, improving interoperability of resources and accomplishing intellectualized service.

Abstract: The present invention relates to the technical field of terminal devices of the Internet of Things, more specifically to a semantic method for terminal devices of the Internet of Things capable of analyzing the application characteristics of terminal devices of the Internet of Things, setting down the rules for building ontology base; analyzing and building initial ontology base by using the ontology base building tool; pre-processing information from network and sensors; collecting information uploaded by sensors, updating the initial ontology base, and expanding the ontology base by collecting information searched by network. The method establishes program plan by object-oriented mode, analyzes implementing results by using existing test data or simulated data, and realizes domain updating and expansion of sensor ontology according to specific applications. The whole development and evolution of sensor ontology is increasing gradually in a spiral form.
