Publication number: 20170295031Abstract: In general, certain embodiments of the present disclosure provide techniques or mechanisms for automatically filtering network messages in an aviation network for an aircraft based on a current system context. According to various embodiments, a method is provided comprising receiving a network message transmitted from a source avionic device to a destination avionic device via one or more network packets within the aviation network. A current system context, indicating an aggregate status of avionic devices within the aviation network, is determined based on monitoring the avionic devices. The network message is analyzed by identifying a plurality of attributes corresponding to header and data fields of the one or more network packets corresponding to the network message. The acceptability of the network message within the current system context is determined based on one or more filter rules that specify what attributes are allowed within a particular system context.Type: ApplicationFiled: April 11, 2016Publication date: October 12, 2017Applicant: The Boeing CompanyInventors: John E.

Patent number: 9667316Abstract: Provided are methods and systems for terrestrial data transmission between aircrafts and external networks connected to gates at airports. This type of data transmission is performed through an electrical power cable that includes multiple conductors interconnecting electrical components of an aircraft and a gate. Each conductor may be used to establish a separate broadband over power line (BPL) communication channel using its own frequency range that does not overlap with frequency ranges of other channels. As such, no radio frequency (RF) shielding is needed in the cable and any standard multi-conductor cable may be used. A channel management unit is used to control allocation of data domains among different communication channels depending on characteristics of the data domains, characteristics of the channels, and other factors. For example, one channel may be designated for secure data transfer of specific data domains, such as aircraft control data.Type: GrantFiled: May 17, 2013Date of Patent: May 30, 2017Assignee: The Boeing CompanyInventors: Nha Thanh Nguyen, Anil Kumar, Timothy M.

Publication number: 20170139049Abstract: An apparatus and method of verifying the trustworthiness of position information from an onboard tracking system on an aircraft. An onboard tracking system message comprising onboard tracking system position information indicating a first position of the aircraft is generated by the onboard tracking system and transmitted to an off board aircraft tracking system via a communications satellite in a satellite communications system. The satellite communications system adds a header comprising transmitter position information identifying a second position for transmission of the onboard tracking system message received by the communications satellite to the onboard tracking system message to form a message. The message is received from the satellite communications system by the off board aircraft tracking system and the first position from the onboard tracking system message is compared to the second position from the header to determine whether the onboard tracking system position information is trustworthy.Type: ApplicationFiled: November 16, 2015Publication date: May 18, 2017Inventors: Siobvan M.

Patent number: 9595096Abstract: Provided are methods, systems, and computer program products for inspecting composite items. Specifically, a method involves analyzing an image of or, more generally, data characterizing condition of a top layer, which is disposed over a bottom layer. The method also involves performing a structural integrity check based on any anomalies detected in the top layer during this analysis as well as based on any anomalies previously detected in the bottom layer. As such, this structural integrity check accounts for characteristics of multiple layers, in some embodiments, all layers applied up to point of this inspection. In addition to the detected anomalies, the structural integrity check may account for previously performed repairs. The structural integrity check may be performed on individual portions of a composite item while, for example, other portions continue receiving a new composite layer, which may be referred to as an inline inspection.Type: GrantFiled: March 10, 2014Date of Patent: March 14, 2017Assignee: The Boeing CompanyInventors: Steven A.

Patent number: 9295032Abstract: Provided are methods and systems for terrestrial data transmission between aircraft and external networks, such as airline networks and/or airport networks. While an aircraft is landed, various data domains may need to be transmitted between the aircraft and such networks using two or more communication channels available to the aircraft. These channels may include wired and/or wireless channels, such as broadband over power line channels, Ethernet channels, Wi-Fi channels, and cellular channels. The available communication channels are allocated to transmit particular data domains based on the security levels of these channels. For example, aircraft control domains may be transmitted using a more secure communication channel than passenger information domains and/or entertainment systems domains. In some embodiments, multiple communication channels may be used to transmit the same domain parsed into multiple transmission packets. The packets are recombined back into the data domain after the transmission.Type: GrantFiled: January 28, 2014Date of Patent: March 22, 2016Assignee: The Boeing CompanyInventors: Anil Kumar, Arun Ayyagari, Timothy M.

Patent number: 9265088Abstract: A software based wireless infrastructure system is provided. The system has a driver that communicates with the network stack and a network interface card (NIC), a station server in communication with the station driver and an 802.1X supplicant or an 802.1X authenticator. Each NIC provides station and/or access point functionality support. The driver drops packets that have been received if the packet has not been authenticated and associated. Packets that have been fragmented or encrypted are unfragmented and decrypted. An association manager is used in conjunction with a configuration table manager to associate stations and access points via management packets. A manager receives 802.1X data packets from the packet processor and sends them up to a station server that communicates with user mode applications and an 802.1X supplicant or an 802.1X authenticator that are used to authenticate and deauthenticate stations and access points. APIs are provided to enable communication between the components.Type: GrantFiled: November 28, 2012Date of Patent: February 16, 2016Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Abhishek Abhishek, Arun Ayyagari, Hui Shen, Krishna Ganugapati, Jiandong Ruan
