For example, an apparatus may include a wireless communication unit to receive at a first Bluetooth device an indication message from a second Bluetooth device, the indication message including a state indication to indicate a non-movement state or a movement state of the second Bluetooth device, the wireless communication unit to transmit to the second Bluetooth device an update message including at least one value to indicate a rate of exchanging messages between the first and second Bluetooth devices, the rate being based on the state indication. | 2015-06-11 |
20150163847 | TECHNIQUES FOR MANAGING THE TRANSFER OF A WIRELESS CONNECTION BETWEEN WIRELESS NETWORKS, CHANNELS OR BANDS - Techniques for managing the transfer of a wireless connection between wireless networks, channels or bands are described. In some embodiments a method may comprise receiving a request to transfer a wireless connection between the enabling device and a dependent device from a first wireless network to a second wireless network, determining that the dependent device can not initiate a connection in the second wireless network, rejecting the request, and initiating, by the enabling device, the transfer to the second wireless network. Other embodiments are described and claimed. | 2015-06-11 |
20150163848 | MULTI-CARRIER CONNECTION MANAGEMENT FOR BANDWIDTH AGGREGATION - The connection management entity apparatus determines a set of modems within coverage of a particular area. Each modem of the set of modems is associated with a particular aircraft and one carrier of a plurality of carriers. The apparatus allocates subsets of modems to each eNB of a set of eNBs. The allocation allows each eNB to communicate with the allocated subset of modems. Each eNB operates on a different carrier. The apparatus may be a eNB. The eNB determines a set of modems within coverage of the eNB. The set of modems is associated with one carrier of a plurality of carriers. The eNB operates on the one carrier. Each modem in the set of modems is associated with a different aircraft. The eNB sends information indicating the set of modems and receives an allocation of a second set of modems in response to the sent information. | 2015-06-11 |
20150163849 | Airborne Data Collection - A meter reading system for communicating with Automated Meter Reading meters. The system includes an airborne platform and a meter data collection system disposed on the airborne platform. The meter data collection system includes antennas, with each of the antennas pointing in a different direction, one from another, and each antenna generally pointing downward when the airborne platform is airborne. The antennas receive meter data from the meters. The meter data collection system also includes transceivers, one each of the transceivers associated with and in signal communication with one each of the antennas. The transceivers receive the meter data through the antennas. A first computer is in signal communication with the transceivers, and receives the meter data from the transceivers. | 2015-06-11 |
20150163850 | REMOTE SENSING DEVICE AND SYSTEM FOR AGRICULTURAL AND OTHER APPLICATIONS - A radio-frequency enabled remote sensing device which can be deployed as a single device or a system of networked devices for gathering environmental data. The device is fully integrated and autonomous. The device operates using solar energy and is battery free due to power saving features of its control module and communications module. The device may operate in a sleep/wake cycle to further conserve power during low light conditions. | 2015-06-11 |
