  • Publication number: 20210346721
    Abstract: A system that generates a three-dimensional model of a tissue surface, for example the inner surface of the heart from two-dimensional image data slices. On this surface, one or more pattern lines are drawn, e.g., by a physician using a user interface, to designate desired lesion(s) on the surface. From the pattern lines, a three-dimensional volume for a lesion can be determined using known constraints. Advantageously, the series of boundaries generated by the three-dimensional volume may be projected back onto the individual CT scans, which then may be transferred to a standard radiosurgical planning tool. A dose cloud may also be projected on the model to aid in evaluating a plan.

  • Publication number: 20210266954
    Abstract: This application provides a data sending method, a data sending apparatus, and a terminal device, to improve utilization of a configured grant resource. The method includes: A terminal device receives a configuration message from a network device. The configuration message is used to indicate a configured grant, and the configuration message includes information about a timer corresponding to the configured grant. The terminal device determines that the configured grant is used for a HARQ process, and starts the timer for the HARQ process. To-be-sent data in the HARQ process is data on a first logical channel. During running of the timer, when there is to-be-newly-transmitted data on a second logical channel, the timer stops running, or a running state of the timer is ignored. The data on the second logical channel is sent by using the configured grant.

  • Patent number: 11082104
    Abstract: A network node for a wireless communication system is configured to localize a user node in a first localization operation carried out at a first frequency; determine an accuracy value associated with the first localization operation; and adjust at least one beam parameter for radio beams to be used in a second localization operation based on the determined accuracy value, the second localization operation carried out at a second frequency that is greater than the first frequency. The network node is configured to determine the accuracy value associated with the first localization operation by tracking a rate of change of an angle of a radio beacon signal transmitted from the user node relative to the network node.

  • Publication number: 20200412444
    Abstract: The invention relates to a method for setting and operating redundant paths in a quantum communication network, wherein a transmitter implements simultaneous transmission of signals on a working path and protection paths. The signal transmitted on the working path is a primary signal, and the signals transmitted on the protection paths are follow-up signals. In a case that the working path is normal, the transmitter forwards the primary signal on the working path level by level, to implement long distance transmission of a quantum signal. In a case that the working path fails, a proxy working path is selected from the remaining protection paths with the highest priority, and the transmission of information is eventually completed on the proxy working path. It can be prevented that unknown quantum information is damaged and becomes unrecoverable during transmission, thereby greatly improving the security, stability, and reliability of information transmission during quantum communication.

  • Publication number: 20200322093
    Abstract: This application provides a client device, a method, and a computer program. The client device obtains a first parameter associated with a radio link failure timer. The first parameter indicates a first time period during which the radio link failure timer is reset and thereafter started. The client device further obtains a second parameter associated with the radio link failure timer. The second parameter indicates a second time period during which the radio link failure timer is started and thereafter reset. Based on the first parameter and the second parameter, the client device determines a value of the radio link failure timer.

  • Patent number: 10771578
    Abstract: Webpage loading methods and devices include, in addition to sending an address of a first webpage to a server, a client further sends a name of a first-webpage resource stored in the client, such that the server can determine, according to the address of the first webpage and the name of the first-webpage resource stored in the client, a first push resource to be sent to the client, where the first push resource is all the resources required for loading the first webpage apart from the first-webpage resource stored in the client, which avoids pushing, by the server to the client, a resource that has been locally stored in the client, and therefore saves a bandwidth resource of a communications network.

  • Patent number: 10764382
    Abstract: Techniques for integrating two server systems are provided. A first server system receives, from a first computing device, provider data generated by a third-party tracking service. The first server system stores association data that associates the provider data with one or more content items. After storing the association data, the first server system receives, from a second computing device, a message that includes a first identifier and that indicates an event and a content item. In response to receiving the message, the first server system determines whether to report the event to the third-party tracking service. If so, the first server system determines a second identifier based on the first identifier, retrieves, based on the association data and the content item, the provider data that is associated with the content item, and transmits, over a network to the third-party tracking service, the second identifier and the provider data.

  • Publication number: 20200073517
    Abstract: Techniques for switching content items to improve presentation of one or more content items are provided. In one technique, a plurality of content items associated with a particular slot in a user interface is received by an application. A first content item of the plurality of content items is caused to be displayed in the particular slot in the user interface presented to a client computing device. After the first content item is caused to be displayed in the particular slot, a user input to scroll through the plurality of content items is received. After scrolling through the plurality of content items, a particular slot is detected to be no longer in view and a second content item from the plurality of content items different from the first content item is selected. The second content item is caused to be displayed in the particular slot by the application.
