20100207732 | Robust Location Distinction Using Temporal Link Signatures - The ability of a receiver to determine when a transmitter has changed location is important for energy conservation in wireless sensor networks, for physical security of radio tagged objects, and for wireless network security in detection of replication attacks. In embodiments of the present invention, a measured temporal link signature is determined to uniquely identify the link between a transmitter and a receiver. The temporal link signature is an impulse response of a transmitted signal from the transmitter over a channel between the transmitter and a receiver over a channel. When the transmitter changes location, or if an attacker at a different location assumes the identity of the transmitter, the proposed link distinction methodology reliably detects the change in the physical channel. This detection can be performed at a single receiver or collaboratively by multiple receivers. | 08-19-2010 |

20150220229 | USER INTERFACE FOR END-OF-BOOK EXPERIENCE CROSSREFERENCE - System and method for presenting a customized aggregation of information based on specific state-of-mind of a user. An end-of-book experience graphical user interface (GUI) is configured to capture a specific state-of-mind of a user by using an options menu listing typical state-of-minds of typical book users. Provided the user indicates to expand reading experience on the instant book, a set of information that facilitates a deep dive experience on the instant book can be presented. Alternatively, provided the user indicates to move on from the instant book, a collection of books of in different categories from the instant can be recommended. The end-of-book experience GUI can be prompted upon a user indication of having finished reading a book, closing the reading program before finishing, or re-reading the book. | 08-06-2015 |
20150220262 | CHANGING SETTINGS FOR MULTIPLE DISPLAY ATTRIBUTES USING THE SAME GESTURE - Content is displayed on a touchscreen display of a computing system such as an electronic book reader. The content is displayed according to a setting for a first attribute (e.g., level of brightness) and a setting for a second attribute (e.g., day mode or night mode). In response to sensing a motion proximate to the touchscreen, the setting for the first attribute is changed to a different value. In response to a value for the setting for the first attribute crossing a threshold value (e.g., while the motion is being performed), the setting for the second attribute is changed. | 08-06-2015 |
