20080292105 | LIGHTWEIGHT KEY DISTRIBUTION AND MANAGEMENT METHOD FOR SENSOR NETWORKS - A lightweight security framework is disclosed that combines PKI with symmetric key cryptography to exploit the system asymmetry in hierarchical sensor networks. The framework provides protocols for public key exchange, session and group key generation, pair-wise key generation, and network resource protection in a low-cost security architecture. The security framework shifts much of the security-related computational load off of the resource-constrained sensor nodes and on to resource-rich base station nodes. The method is based on the generation and management of two kinds of symmetric keys from a set of bootstrapping asymmetric keys on each node. | 11-27-2008 |
20090328136 | TECHNIQUES FOR ROUTING PRIVACY SENSITIVE INFORMATION TO AN OUTPUT DEVICE - Various embodiments are directed to a privacy routing engine embodied on a device and a method for routing actuations to preserve a user's privacy. The privacy routing engine may receive actuations intended for a user, and may route the actuation to an output device according to a set of user output policies. The user output policies may specify output devices according to a user's context and need for privacy. A user context may include a location, an event, or a sensed condition. Other embodiments are described and claimed. | 12-31-2009 |
20100071482 | Method and apparatus for scanning a textile - Some embodiments disclosed herein provide novel approaches for rapidly sensing sense line cross-point interaction in a textile such as a carpet or rug. | 03-25-2010 |
20110242043 | DEVICE WITH CAPACITIVE TOUCHSCREEN PANEL AND METHOD FOR POWER MANAGEMENT - Embodiments of a device having a touchscreen panel and method for reducing power consumption are generally described herein. The touch-sensing capability of the touchscreen panel is activated when user interaction with the touchscreen panel is detected. The touch-sensing capability of the touchscreen panel is deactivated when no user interaction is detected. In some embodiments, the device includes a touch-event detector to sense motion or vibration, and processing circuitry to either activate or deactivate touch-sensing capability of the touchscreen panel based at least in part on input from the touch-event detector. | 10-06-2011 |

20150086949 | USING USER MOOD AND CONTEXT TO ADVISE USER - Various systems and methods for using a user's mood and context to advise a user are described herein. Data may be received at a mobile device, the mobile device associated with the user. A mood of the user is determined based on the data. An event involving the user is identified and advice is provided to the user regarding the event, the advice based on the received data, the mood, and the event. | 03-26-2015 |
20150127813 | CONTEXTUAL BROWSER COMPOSITION AND KNOWLEDGE ORGANIZATION - Various systems and methods for organizing knowledge are described herein. A context of a browsing session of a plurality of online resources is identified. User browsing behavior during browsing of the plurality of online resources is tracked. Using a computing device, a relevance metric of the plurality of online resources is determined using the user browsing behavior, with the relevance metric measuring a relevance of the plurality of online resources in view of the context. The relevance metric, an indicia of the context, and the plurality of online resources are stored in a database on the computing device. | 05-07-2015 |
20150323981 | COORDINATED MULTI-DEVICE POWER MANAGEMENT - Techniques related to coordinating power management for multiple devices are discussed. Such techniques may include establishing communications between devices, inventorying the components of each device, and implementing a power management plan to eliminate any redundancy in the components and reduce the total power consumed by the devices. | 11-12-2015 |
