    摘要: A computer implemented method includes transmitting a transmit command to a first data concentrator to send out a predetermined signal of predetermined characteristics according to a transmission setting, receiving a received signal from at least one second data concentrator, and determining if there are any signal transmission effects between the first data concentrator and the second data concentrator based on a comparison of the predetermined signal and the received signal.

    摘要: Apparatus and associated methods relate to selectively bypassing a daisy-chained network device based on a timing of a series of reset signals. The daisy-chained network device is bypassed if an elapsed time from a last of the reset signals of the series is longer than a predetermined time period. While no interval between adjacent reset signals of the series exceeds the predetermined time period, the daisy-chained network device is not bypassed. In some embodiments, the daisy-chained network device generates the series of reset signals. If the daisy-chained network device fails to generate a next reset signal within the predetermined time period as measured from a previous reset signal, the daisy-chained network device is bypassed. If the daisy-chained network device loses power, it will be bypassed as the reset signals will not be generated, but if the daisy-chained network device regains power, it can be reinserted into the network daisy-chain.

    摘要: A multi-level network system of an aircraft includes at least one equipment area network and a wide area network. The equipment area network includes equipment of the aircraft, at least one wireless device, and at least one equipment area network coordinator. The at least one wireless device is configured to transmit and receive data using a first wireless link. The at least one equipment area network coordinator is configured to transmit to and receive data from the at least one wireless device using the first wireless link and to transmit data to and receive data from the wide area network using a second wireless link, the first wireless link using lower power than the second wireless link. The wide area network includes a wide area network coordinator that is configured to transmit and receive data from the at least one equipment area network coordinator using the second wireless link.

    摘要: A method can include generating reference image data representing a field of view of an interior of a fuel tank, and generating active image data representing the field of view of the interior of the fuel tank when the fuel tank contains fuel. The method can further include producing, by a processing device, a fuel measurement value representing an amount of fuel contained in the fuel tank based on the reference image data and the active image data, and outputting, by the processing device, an indication of the fuel measurement value.

    摘要: A portable wireless communications adapter includes a wireless receiver, a wireless transmitter, an electronic interface connector, and a location sensing module. The wireless receiver is configured to receive wireless data over a Wireless Avionics Intra-Communication (WAIC) frequency range between 4.2 gigahertz (GHz) and 4.4 GHz. The wireless transmitter is configured to send wireless data over the WAIC frequency range between 4.2 GHz and 4.4 GHz. The electronic interface connector is configured to mate with a portable electronic device for communication of the wireless data with the portable electronic device. The location sensing module is configured to determine a location of the portable wireless communications adapter relative to an interior of an aircraft based on WAIC communications received at the wireless receiver and selectively enable and disable the wireless transmitter based on the determined location.
