Abstract: A lidar system includes one or more light sources configured to generate a first beam of light and a second beam of light, a scanner configured to scan the first and second beams of light across a field of regard of the lidar system, and a receiver configured to detect the first beam of light and the second beam of light scattered by one or more remote targets. The scanner includes a rotatable polygon mirror that includes multiple reflective surfaces angularly offset from one another along a periphery of the polygon mirror, the reflective surfaces configured to reflect the first and second beams of light to produce a series of scan lines as the polygon mirror rotates. The scanner also includes a pivotable scan mirror configured to (i) reflect the first and second beams of light and (ii) pivot to distribute the scan lines across the field of regard.

Abstract: In an onboard aircraft computing and network system, an Aeronautical Radio, Incorporated (ARINC) 629 Ethernet converter receives ARINC 629 data, transcodes the data, and inserts the data into Ethernet frames for transmission to other onboard devices. A secure communications session may be established for transmission of the transcoded data. ARINC 629 data may be received by an ARINC 629 Ethernet converter on several buses used by onboard devices.
