  • Publication number: 20190175158
    Abstract: A system and method for compensation of angular distortions in a system utilizing light emitters and light sensors disposed on non-parallel jaws may include determining a first point at a first side of a region of interest and a second point at a second side of the region of interest, determining a linear curve including the first and second points, and utilizing the linear curve to remove the angular distortion from the region of interest between the first and second points, A system and method for compensation of angular distortions may alternatively include modeling a non-pulsatile illumination pattern according to the intensities of individual emitters, comparing the pattern according to the model against a non-pulsatile illumination pattern detected using the light sensors, and varying the intensities of the individual emitters based on the comparison until angular distortion has been removed.

  • 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.

  • Patent number: 9778952
    Abstract: A customer network client detects, through a user interface, selection of a graphical representation of a set of virtual machine images and an indication to migrate this set of virtual machine images to an off-premises network managed by a computing resource service provider. In response, the client generates a set of application programming interface calls, which may be transmitted to the service provider and causes the service provider to convert the selected images for use within the off-premises network. The client monitors fulfillment of the calls and, upon determining that the calls has been fulfilled, updates a portion of the user interface associated with the computing resource service provider to indicate that the images may be instantiated within the off-premises network.
