20090292888 | Backing up Data from Backup Target to Backup Facility - Aspects of the subject matter described herein relate to backup up data. In aspects, a backup target determines a degree to which a data set included on the backup target is not backed up on a backup facility. The degree can represent more than just that the data set is completely backed up or is not backed up at all. If the degree satisfies a condition, the backup target utilizes information derived from a backup history of one or more attempted or successfully completed backup sessions between the backup target and the backup facility to determine whether to provide a notification regarding backup state. The backup target also may send the degree and other backup information to a backup facility which may use this information in determining a backup scheme to employ with the backup target. | 11-26-2009 |
20100110081 | SOFTWARE-AIDED CREATION OF ANIMATED STORIES - Software-assistance that allows a child or other author to generate a story. The author may generate their own content and add that author-generated content to the story. For instance, the author could drawn their own background, background items, and/or characters. These drawn items could even be added to a library so that they could be reused in other stories. The author can define their own animations associated with characters and background items, rather than selecting predefined animations. The story timeline may also keep track of events that are caused by the author interacting with the story in particular ways, and that represents significant story changes. The author may then jump to these navigation points to delete the event thereby removing the effects of the story change. | 05-06-2010 |

20100119020 | Blanking Techniques in Receivers - An aspect of the present invention detects the presence of interference by examining an input signal received on an input path, and blanks the receiver if interference is detected. Information contained in the input signal may be recovered otherwise. In an embodiment, the duty cycle of a jamming signal is determined by examining the input signal, and a threshold strength having a positive correlation with the duty cycle is determined. If the strength of the jamming signal during the on-interval (start and end of the interference in each cycle) is greater than the threshold strength, then only the receiver is blanked. Otherwise, no blanking is performed, and only the gain of an amplifier in the path from the input path to a baseband processor is reduced. According to another aspect, one or more cycles of the interference is used to detect the start of interference and the receiver is blanked when interference is present. | 05-13-2010 |
