| 20090113296 | DISPLAYING A MAP AND ASSOCIATED SYMBOLIC CONTEXT INFORMATION - A map of a destination and its immediate surroundings are displayed at a relatively low level. Symbolic context information is displayed simultaneously, in order to provide a higher-level context for the location. The symbolic context information can include such things as nearby highways, exits, bridges, sports venues or other landmarks and points of interest. The symbolic context information can be displayed, for example, on the perimeter of the map, or on the map in a distinct visual style such as a different color or font or fish-eye view. As the map is updated, (for example if the user zooms in or out), the context information is updated as well. The context information can be interactive, and can display the relationship between the context item and the location being mapped. | 04-30-2009 |

| 20090178098 | SYSTEM FOR REMOTELY CONTROLLING CLIENT RECORDING AND STORAGE BEHAVIOR - A system for remotely controlling client recording and storage behavior schedules the recording, storing, and deleting of multimedia content on a client system storage device. The invention accepts as input a prioritized list of program viewing preferences which is compared with a database of program guide objects that indicate when programs of interest are actually broadcast. A schedule of time versus available storage space is generated that is optimal for the viewer's explicit or derived preferred content. The viewer may request that certain content be captured, which results in the highest possible priority for those content. The invention provides objects called a capture requests that are sent by the service to client systems. Capture requests reflect local storage management decisions about how the client system storage is partitioned. Capture requests also allow the service to determine content to be recorded by the client system in the same manner that a viewer requests that certain content are recorded but are more powerful than what a viewer can request. Recording requests for a capture request can preempt viewer requests or be entered at the same or lower priority as a viewer request. Capture requests can adjust all aspects of a recording request and affect the capture request itself. Client system operational functionality are also manipulated by the service using capture requests. | 07-09-2009 |

| 20080222165 | Method and system for providing universal remote control of computing devices - A universal console (UC) platform for a UC device is provided. The user sets up or initializes the UC by describing his or her preferences and disabilities. The UC digests and stores this user information. Later, as the user encounters various devices and applications to be controlled, and indicates a desire to control a particular device, the device to be controlled or other source sends a canonical user interface (UI) description of the device's UI to the UC. The canonical UI description adheres to an abstract format to describe in high-level terms the functionality of the device's UI. From the canonical UI representation, the UC device is capable of recognizing (1) the action-commands to which the device responds including parameters and (2) the decisions, selections, and input the user needs to provide for the console to determine which action-commands to send and the values of the action-command parameters. Generally, this implicates group hierarchy, from which the user is able to choose what he or she wants the device to perform, and the UC is able to gather the parameter values associated with the action-commands to carry out the user's wishes. Additionally, the UC device is capable of receiving status, state changes and other notifications from a device within its control. | 09-11-2008 |

| 20100067691 | Document certification and authentication system - This invention safeguards the integrity of a machine-printed paper document by entangling a characteristic signature derived from the document's paper grain structure with the identities of the printing device and the person or organization which issued the document. This protection is achieved using a certification phase performed by an augmented document printer and an authentication phase performed by an augmented document scanner. In the certification phase, the grain structure of a specific area of the original paper is imaged and processed to generate a unique signature for the paper. This signature is doubly encrypted using the private keys of the augmented printer and the certifier. These encryption steps entangle the signature of the paper with its source information in a way that thwarts counterfeiting attacks which either copy the document or falsely attribute its source to a specific printer and/or certifier. | 03-18-2010 |
