  • Patent number: 9020658
    Abstract: A system for detecting a mass tamper event affecting a vehicle mass record for a vehicle being monitored includes a body bounce frequency estimator configured to estimate body bounce frequency for the vehicle and a mass estimator configured to estimate a vehicle mass, m, according to the equation (I), where k is a constant relating to a suspension system in the vehicle and ?b is the estimated body bounce frequency. A first comparator compares the estimated vehicle mass value with an alternative vehicle mass value and identifies a mass tamper event when the estimated vehicle mass value differs from the alternative vehicle mass value by more than a pre-determined amount. An interface communicates mass tamper event data to a remote device. A system and method for recording vehicle mass data are also provided.

  • Patent number: 6882930
    Abstract: The invention provides a system for providing traffic or related information including: a database storing historical traffic data being operable to receive substantially real time traffic data and associated data; means for integrating historical, real time and associated traffic data with respect to traveller profiles to produce customized forecasted traffic information with respect to those traveller profiles; and means for sending the customized forecasted traffic information to an intended recipient wherein the customized forecasted traffic information includes predicted travel delays for travel routes described in the traveller profiles.
