Abstract: A vehicle monitoring device includes a camera or other optical sensor configured to be disposed at a trailing end of a first vehicle system. The camera or other optical sensor is configured to output one or more images or video of a field of view behind the first vehicle system. The monitoring device also includes a controller configured to receive output from one or more sensors and to activate the camera or other optical sensor to output the one or more images or video based on the output from the one or more sensors. The output from the one or more sensors indicates one or more of a change in movement of the first vehicle system, a temperature, an acoustic sound, or movement of a second vehicle system.

Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: An insertable flow meter assembly includes a flow measuring device configured to be inserted into a flow passage of a receiving structure. The flow measuring device is configured to enable determination of a flow rate of fluid through the flow passage, the flow measuring device is formed as a single continuous structure, and an outer cross-section of at least a portion of the flow measuring device is configured to be substantially the same as an inner cross-section of the flow passage. The insertable flow meter assembly also includes an end cap configured to engage an exterior surface of the receiving structure and to couple to the receiving structure at an end of the flow passage. The end cap is configured to block movement of the flow measuring device out of the end of the flow passage.
