  • Publication number: 20240185489
    Abstract: An analytic chart data store may contain an enterprise information data structure, based on a result set received from a back-end application computer server, and a user selectable dimension ungrouping indication. The enterprise information data structure may include: an outermost dimension arranged on a row axis; an innermost dimension arranged on the row axis; and measure values arranged on the row axis. A computer processor of an analytic chart creation platform may determine that the user selectable dimension ungrouping indication is set to “ungroup.” Responsive to said determination, the analytic chart creation platform may automatically re-organize the enterprise information structure such that the innermost dimension information is arranged on the column axis instead of the row axis. The analytic chart creation platform may then automatically create an analytic chart and transmit the chart to a remote user device.

  • Patent number: 12001615
    Abstract: A workstation enables operation of a 2D input device with a 3D interface. A cursor position engine determines the 3D position of a cursor controlled by the 2D input device as the cursor moves within a 3D scene displayed on a 3D display. The cursor position engine determines the 3D position of the cursor for a current frame of the 3D scene based on a current user viewpoint, a current mouse movement, a CD gain value, a Voronoi diagram, and an interpolation algorithm, such as the Laplacian algorithm. A CD gain engine computes CD gain optimized for the 2D input device operating with the 3D interface. The CD gain engine determines the CD gain based on specifications for the 2D input device and the 3D display. The techniques performed by the cursor position engine and the techniques performed by the CD gain engine can be performed separately or in conjunction.

  • Patent number: 12003671
    Abstract: Voicemail spam detection is performed based on content of voicemail messages. The content of an incoming voicemail message is compared to a spam template that includes a representation of a spam voicemail. Spam templates may be generated based on spam indications provided by users for voicemail messages they have received. User indications for sufficiently similar voicemail messages may be aggregated by maintaining a vote count for a spam template that reflects how many times a user has indicated a matching voicemail message is spam. A spam template may also include an occurrence count that reflects how many times voicemail messages matching a spam template have been detected in a telephony system. An incoming voicemail message may be compared to spam templates and, responsive to a match of content and/or a corresponding vote count or occurrence count meeting a condition, the voicemail message may be identified as spam.
