Abstract: The present disclosure is generally directed to systems and methods for updating functionality of vehicular computing devices. In particular, these systems and methods utilize an intermediary courier device to propagate update packages from an update server to a vehicular computing device. The courier device obtains the update package while connected to a first network, e.g., the Internet, and transfers the update package to the vehicular computing device when in communication with the vehicular computing device. The vehicular computing device then installs the update package when doing so is compatible with an operation state of the vehicle (or an operation state of the vehicular computing device). The vehicular computing device may schedule installation of the update package for a time when the operation state is compatible with installation of the update package.

Abstract: A high power multi-frequency laser includes a laser cavity defined by reflective elements, a frequency routing device in the cavity comprising a plurality of frequency selective pathways, a first set of optical amplifiers optically coupled to a first end of the frequency routing device, and a second set of optical amplifiers optically coupling a second end of the frequency routing device and a first one of the reflective elements. The high power multi-frequency laser further includes a power combiner. The power combiner is optically coupled to the first set of optical amplifiers and a second one of the reflective elements and combines the outputs of the first set of optical amplifiers such that a common output for the multi-frequency laser is provided. The common output of the present invention provides a single output from the multi-frequency laser having a high output coupling efficiency.
