Abstract: A multifactor authentication system onboard a vehicle including at least one processor, a first database, a second database, and one or more protected computer systems is provided. The at least one processor is programmed to receive, from a user, a request for access to the one or more protected computer systems, wherein the request contains authentication information including a first authentication factor and a second authentication factor, retrieve first factor authentication data associated with the user from the first database, compare the first factor authentication data with the received first authentication factor to determine if there is a match, retrieve the second factor authentication data associated with the user from the second database, compare the second factor authentication data with the received second authentication factor to determine if there is a match, and grant access to the one or more protected computer systems if all of the comparisons match.

Abstract: A broadband over powerline (BPL) unit is provided. The BPL unit includes at least one processor programmed to execute a first virtual machine and a second virtual machine, at least one memory device in communication with the at least one processor, and a powerline transceiver. The at least one processor is programmed to transmit and receive data over a three-phase power line via the powerline transceiver. The at least one processor is also programmed to receive, via the first virtual machine, a first plurality of data for transmission via the powerline transceiver, receive, via the second virtual machine, a second plurality of data for transmission via the powerline transceiver, transmit, via the powerline transceiver, the first plurality of data via a first phase, and transmit, via the powerline transceiver, the second plurality of data via a second phase.

Abstract: Aircraft partitions include a body panel and a partition mounting portion that selectively and removably couples the body panel to an aircraft passenger cabin. The body panel may indicate a transition between a first section of an aircraft passenger cabin and a second section of the aircraft passenger cabin, and at least a portion of the body panel may be an electrochromic region that comprises an electrochromic material. The electrochromic region may have a selectively adjustable transparency and/or may display information and/or entertainment to passengers. Aircraft may include such an aircraft partition and an aircraft mounting portion for selectively and removably coupling the aircraft partition to the aircraft passenger cabin via the partition mounting portion.
