  • Footwear system for ulcer or pre-ulcer detection
    Patent number: 11395622
    Abstract: A footwear system having a plurality of temperature sensors determines the emergence of an ulcer or pre-ulcer on a person's foot. After the plurality of temperature sensors generate a plurality of discrete temperature data values, the system and method form a temperature map representing substantially the actual geometric shape of at least a portion of the foot, and the distribution of temperatures of the at least a portion of the foot. Next, the method and system determine whether the temperature map presents at least one of a plurality of prescribed patterns, and produces output information indicating an emergence of an ulcer or a pre-ulcer on a given portion on the foot. The output information is produced as a function of whether the temperature map is determined to present the at least one of the plurality of prescribed patterns.

  • Method and apparatus for implementing a scene-graph-aware user interface manager
    Patent number: 7290216
    Abstract: One embodiment of the present invention provides a system that enables a user interface manager to modify a scene graph for an application. During operation, the system receives the scene graph for the application, wherein the scene graph defines visual attributes for a user interface associated with application. Next, the system uses the scene graph to render a visual output for the user interface, and displays the visual output to a user of the application. The system also enables the user interface manager to modify the scene graph, whereby the user interface manager can produce visual effects for the user interface in addition to visual effects produced by the application.
