Abstract: The present disclosure relates to devices, lidar systems, and vehicles that include optical redirectors. An example lidar system includes a transmitter and a receiver. The transmitter includes at least one light-emitter device configured to transmit emission light into an environment. The receiver is configured to detect return light from the environment and includes a plurality of apertures, a plurality of photodetectors, and a plurality of optical redirectors. Each optical redirector is configured to optically couple a respective portion of return light from a respective aperture to at least one photodetector of the plurality of photodetectors. Each optical redirector also has a rotational orientation relative to other optical redirectors such that the redirection paths of optical redirectors that correspond to adjacent apertures are not coplanar with one another.

Abstract: A computer-implemented tool having a collection of content management subsystems allows the content creator to construct a web-based behavioral modification site without the need for computer programming skills. The content delivery system constructed with this tool employs a lesson manager that delivers lesson content based on a tree structure; a virtual educator manager that presents different graphical images of an educator character, complete with different facial expressions and gestures designed to facilitate learning; a link manager that supplements lesson content with links to supplemental material and automatically suppresses dead links; and an impact manager that automatically administers a stage-of-change questionnaire a predefined time interval after the lesson was completed.
