Appl. No.:

11/381117

Inventors:

Raffaele Sena - Cupertino CA, US
Nathaniel D. Monson - Mountain View CA, US
Kevin Lynch - Los Altos CA, US
Keith Kitani - San Jose CA, US

Assignee:

Adobe Systems Incorporated - San Jose CA

International Classification:

G06F 17/30

US Classification:

707101, 7071041, 707102, 707201

Abstract:

The present invention teaches a digital media file conversion and integration system including a server coupled to the Internet to allow users to download media files to a server the Internet. The system contains devices to screen, compress, and update the media files, devices to break down the media files into low level components, devices to convert one or media files to an intermediate format and then combine the intermediate formats to create an output format, devices to convert output formats to a presentation file, electronic storage to allow third party access to the presentation file through the Internet or email. Presentation files can be created for electronic devices such as portable digital assistants or cellular phones. Users can choose from several output formats. Users can subscribe to the presentation service or pay per use.

US Classification:

Abstract:

Techniques that optimize performance of simultaneous localization and mapping (SLAM) processes for mobile devices, typically a mobile robot. In one embodiment, erroneous particles are introduced to the particle filtering process of localization. Monitoring the weights of the erroneous particles relative to the particles maintained for SLAM provides a verification that the robot is localized and detection that it is no longer localized. In another embodiment, cell-based grid mapping of a mobile robot's environment also monitors cells for changes in their probability of occupancy. Cells with a changing occupancy probability are marked as dynamic and updating of such cells to the map is suspended or modified until their individual occupancy probabilities have stabilized. In another embodiment, mapping is suspended when it is determined that the device is acquiring data regarding its physical environment in such a way that use of the data for mapping will incorporate distortions into the map, as for example when the robotic device is tilted.
