摘要:
Techniques for managing detection, dynamic allocation, and sharing of available spectrum via cognitive radio systems and dynamic spectrum sharing. In some cases, RF carriers (e.g., secondary carriers or secondary cells) are not permanently assigned to base stations, user terminals, or the network. A base station can request allocation of secondary carriers using a reservation request. The assigned secondary carriers can be released and made available for assignment to another base station or radio access network.

Technologies for context-based management of wearable computing devices include a mobile computing device and a wearable computing device. The wearable computing device generates sensor data indicative of a location context of the wearable computing device and transmits the sensor data to the mobile computing device. The mobile computing device generates local sensor data indicative of a location context of the wearable computing device and fuses the local sensor data with the sensor data received from the wearable computing device. The mobile computing device determines a context of the wearable computing device based on the fused sensor data. The mobile computing device determines whether an adjustment to the functionality of the wearable computing device is required based on the determined context. The mobile computing device manages the functionality of the wearable computing device in response to determining that an adjustment to the functionality is required.

Some demonstrative embodiments include apparatuses, systems and/or methods of estimating an orientation of a mobile device. For example, an apparatus may include an orientation estimator to receive an indication of first and second consecutive steps of a user carrying a mobile device, to determine an angular rotation of an orientation parameter between the first and second steps, and to determine a value of the orientation parameter based on a comparison between the angular rotation and at least one predefined angular rotation threshold.

Various embodiments are generally directed to techniques to merge a virtual map derived from sensors of computing devices moved about an interior of a structure with a corresponding physical map. An apparatus to merge maps includes a processor component; and a merged map generator for execution by the processor component to merge a virtual map and a physical map to generate a merged map, the virtual map comprising indications of virtual pathways through an interior of a structure based on sensors, and the physical map comprising indications of physical pathways of the interior. Other embodiments are described and claimed.
摘要:
A location of a wireless device relative to a vehicle is determined using received data. Data may be received from the vehicle sensors. Data may also be received from the wireless device sensors of a wireless device. The presence of one or more persons may be determined using received data. A user-to-wireless device association may be detected based, at least in part, upon the presence of one or more persons in the vehicle and the location of the wireless device relative to the vehicle.
摘要:
A method of detecting a revisit position includes receiving at a computing system a plurality of position data points, each of the plurality of position data points including a signal scan measurement. The method farther includes calculating a first signal distance between a first signal scan measurement corresponding to a first position data point of the plurality of position data points and a second signal scan measurement corresponding to a second position data point of the plurality of position data points. The method further includes determining that the first signal distance is less than a first threshold, that the first signal distance is a local minimum for the first position data point, and the first signal distance is a local minimum for the second position data point. The method further includes, based on the determining, identifying the first and second position data points as revisit points.
