Patent ID: 8115620

Claim:
An asset including an arrangement for monitoring an interior of the asset, comprising: a wake-up sensor that detects occurrence of an internal or external event relating to the condition or location of the asset; an energy source arranged on the asset for providing power; a sensor system arranged on the asset and applying micropower impulse radar (MIR) to obtain data about at least one object in the interior of the asset in response to detection of the occurrence of an internal or external event by said wake-up sensor such that after said wake-up sensor detects the occurrence of an internal or external event, said sensor system obtains data about the at least one object in the interior of the asset; a location determining system arranged on the asset, said location determining system being arranged to monitor the location of the asset; and a communication system arranged on the asset and coupled to said sensor system and said location determining system, said communication system being arranged to transmit the data about the at least one object obtained by said sensor system in response to detection of the occurrence of an internal or external event by said wake-up sensor and the location of the asset provided by said location determining system to a remote facility, said sensor system being connected to said energy source and since said sensor system is operative in response to detection of the occurrence of an event by said wake-up sensor, power from said energy source is conserved.
