  • Publication number: 20210028981
    Abstract: At a network-accessible service, a request is received from a client to enable access by a migration facilitator to a configuration record collection of the client. A response to a migration candidate identification query is generated using the configuration record collection and transmitted to the facilitator. An indication of a proposal associated with migrating at least a portion of the client's computing environment to a different computing environment with assistance from the facilitator is provided to the client.

    Abstract: A surgical system includes at least one light emitter generating light at a first intensity and an array of light sensors including a least one row of light sensors, individual light sensors in the row of light sensors adapted to generate a signal including a non-pulsatile component. The system also includes a controller coupled to the array of light sensors, the controller including an analyzer to determine the magnitudes of the non-pulsatile components at the individual light sensors in the row of light sensors, to determine if the non-pulsatile component transitions from a higher magnitude to a lower magnitude and from a lower magnitude to a higher magnitude, and if so, to determine if the first intensity should be changed to a second intensity.

  • Publication number: 20200242527
    Abstract: Methods, systems and computer program products for recommending remediation actions to selected users of collaboration systems. Certain disclosed techniques commence upon observing user-to-object interactions and user-to-user interactions raised by users of a collaboration system. A first specialized data structure is populated with activity values that characterize user-to-object interactions raised by individual users. A second specialized data structure is populated with sharing values that characterize observed sharing events over shared content objects. The values of the first data structure are correlated to the values of the second data structure to calculate a total contribution amount for each of the users of the collaboration system. A small set of communication recipients is identified by ranking the individual users based on a calculated total contribution amount. To avoid wasteful messaging to all users of the collaboration system, messages are sent only to the small set of recipients.

  • Patent number: 10212031
    Abstract: At a configuration discovery service, a unique service-side identifier is generated for a configuration item based on analysis of a data set obtained from a first data source. A determination is made that a second data set, which does not contain the service-side identifier and is obtained from a different data source, also includes information pertaining to the same configuration item. A coalesced configuration record for the configuration item is prepared. The coalesced configuration record is stored at a repository and used to respond to a programmatic query.

  • Publication number: 20190028355
    Abstract: A network-based discovery system and service are disclosed that provide client discovery services to a number of clients over a network. The network-based discovery system includes a database that stores discovery information of client network-based resource configurations. The discovery information may be obtained from client resources by client-side discovery components that are placed on client resources, obtain the discovery information and that send the information to the discovery system. The discovery system analyzes the discovery information to determine the client network-based resource configurations and generates client network-based resource configuration representations for the respective clients. The client network-based resource configuration representation may include a description of, and dependencies among, a plurality of computer-based resources.
