Abstract: An automated exchange for determining the availability of mobile assets that are shareable among mobile asset users. The automated exchange includes a plurality of mobile asset sources for providing mobile assets of one or more types, a data center for providing the availability status of each mobile asset, and asset status and availability inputs having communication connection to the data center. The asset status and availability inputs include mobile asset sensors, asset monitoring sensors, manual inputs, and asset status and availability record. A processor located at the data center determines the availability of each mobile asset using the status and availability input data. The processor also receives and processes requests for available mobile assets. A user computer having a communication link to the data center provides user access to information relating to the availability of the mobile assets and user interface to request for available mobile assets.

Abstract: A system for tracking and monitoring the intermodal status of cargo trailers. In addition to the information provided by a Global Positioning System (GPS) unit, the system monitors the status of various sensors on the trailer. The GPS unit provides the location and velocity of a trailer. A wheel monitoring unit provides the status of the wheels of the trailer, specifically whether there is rotation of the wheels or not. Anti-lock braking systems are used to provide signal information indicative of the wheel rotation status. An independent wheel rotation sensor is also used to provide the wheel rotation status. A computer processor determines the intermodal movement status of the trailer using the wheel rotation status and the location and velocity information.
