Abstract: An imaging system includes a camera and a controller. The camera is configured to be disposed on a first vehicle system or at a wayside location along a route to generate image data within a field of view of the camera. The controller is configured to monitor a data rate at which the image data is provided from the camera. The controller also is configured to identify a stimulus event within the field of view of the camera based on a change in the data rate at which the image data is generated by the camera.

Abstract: An improved vehicle jack and jack stand is provided, used separately or in combination, where the both the vehicle jack and jack stand are adapted to receive and support a cup means that also supports a block. The block is able to be interchanged with other blocks to accommodate virtually any type of vehicle. A single jack is able to be used with multiple jack stands, since each jack stand is able to provide support at the identical location as the jack does. This is extremely useful on vehicles with uni-body construction. The jack stand defines an adjustable head, where the head is able to fit between side members of the jack stand, so that both the jack and jack stand are able to be concurrently positioned beneath the cup and block means. The jack stand also provides a removable cross support, which allows the jack stand to be moved in or out of position while the jack is being used to elevate an automobile. The support is replaced prior to the time that the vehicle is lowered onto the jack stand.
