Abstract: Apparatuses and methods for determining the useful life status of a structure, such as a vehicular trailer, by predicting failure at a specific location on the structure are disclosed. The system includes one or more sensors placed at one or more selected locations on the structure, the selected locations being apart from the specific location, for generating data signals related to one or more variables measured at the selected locations. A network is included for gathering and combining the data signals generated by the one or more sensors. A processor is included for comparing the data signals with a predetermined expected failure value in order to predict failure at the specific location on the structure, thereby determining the useful life status of the structure.

Abstract: The present invention relates to an electromagnetic antilock brake system which comprises an electromagnetically actuated release arm capable of adjusting the position of a cam or other motion linkage to result in a controlled application of brake shoes to a brake drum. The invention further comprises a control system for controlling the actuation and release of the ABS.
