20100091756 | METHOD OF USING ACKNOWLEDGMENT TONES FOR DATA CONSISTENCY IN INTRA-VEHICULAR WIRELESS NETWORKS - A method for providing electronic communications between wireless nodes includes wirelessly transmitting data from a transmitting one of the nodes to a plurality of receiving ones of the nodes. A respective first acknowledgment tone is wirelessly transmitted from each of the receiving nodes to the transmitting node and to each other one of the receiving nodes. Each first acknowledgment tone is transmitted in response to the respective receiving node receiving the transmitted data. Each of the first acknowledgment tones is transmitted in a respective, unique time slot. At least one second acknowledgment tone is wirelessly transmitted from at least one of the nodes to each other one of the nodes. The second acknowledgment tone is transmitted dependent upon whether a group of received first acknowledgment tones matches a group of expected-to-be-received first acknowledgment tones. | 04-15-2010 |

20110304503 | SIMULTANEOUS LOCALIZATION AND RF MODELING - The simultaneous localization and RF modeling technique pertains to a method of providing simultaneous localization and radio frequency (RF) modeling. In one embodiment, the technique operates in a space with wireless local area network coverage (or other RF transmitters). Users carrying Wi-Fi-enabled devices traverse this space while the mobile devices record the Received Signal Strength (RSS) measurements corresponding to access points (APs) in view at various unknown locations and report these RSS measurements, as well as nay other available location fix to a localization server. A RF modeling algorithm runs on the server and is used to estimate the location of the APs using the recorded RSSI measurements and any other available location information. All of the observations are constrained by the physics of wireless propagation. The technique models these constraints and uses a genetic algorithm to solve them, thereby providing an absolute location of the mobile device. | 12-15-2011 |
20120321009 | MULTIPLE INDEPENDENT NARROW CHANNELS IN WIRELESS NETWORKS - A multiple independent narrow-channel wireless network and method for transmitting and received data over a wireless network using a fragmented frequency spectrum. The system and method uses a plurality of narrow wireless channels obtained from splitting a wide wireless channel. Each narrow channel performs sending, receiving, and carrier sensing. Moreover, each narrow channel is independent such that data can be sent or received without any interference from other narrow channels and without synchronization. Embodiments of the system and method include a compound radio having a compound receiver and a compound transmitter. The compound transmitter includes an inter-radiolet symbol synchronization module, to permit use of a single inverse fast Fourier transform block, and a dynamically configurable filter array, to mitigate leakage between channels. The compound receiver uses fraction data rate processing to optimize efficiency. A throughput maximal metric technique is used to determine its frequency of operation in white spaces. | 12-20-2012 |

20120320887 | WIRELESS COMMUNICATIONS - The claimed subject matter provides a method for wireless communications. The method includes transmitting, by a first node in a wireless network, a first preamble. The method also includes detecting, in parallel with transmitting the first preamble, a transmission of a second preamble. A second node in the wireless network transmits the second preamble. Additionally, the method includes determining a later start between the transmission of the first preamble and the transmission of the second preamble. The method further includes terminating transmission of the first preamble the determining indicates that the transmission of the first preamble started after the transmission of the second preamble. | 12-20-2012 |

20130232185 | MANAGING DISTRIBUTED APPLICATIONS USING STRUCTURAL DIAGRAMS - Embodiments are directed to providing a structural diagram to collect user input data in a non-linear manner and to managing multiple distributed application models using a structural diagram. In one scenario, a computer system receives a user input specifying a distributed software application that is to be managed across various different computer systems. The computer system determines, based the specified distributed application, which nodes are to be displayed in a structural diagram, where the nodes of the structural diagram represent application properties for managing the specified distributed software application. The computer system then provides a structural diagram that displays the determined nodes. The nodes allow non-linear configuration of the specified application across the various computer systems. | 09-05-2013 |
