Method and apparatus for detecting cargo state in a delivery vehicle. A method is provided for determining a cargo state in a delivery vehicle. The method includes sensing a cargo state change, and determining whether or not the delivery vehicle is in motion. The method also includes storing the cargo state change if it is determined that the delivery vehicle is not in motion.

A method for inventorying and monitoring an asset located in an vehicle asset management area. The method involves an inventorying of a presence of an asset within an vehicle asset management area based on a detection of a RFID tag associated with the asset within the vehicle asset management area, and a monitoring of the inventoried presence of the asset within the vehicle asset management area based on the RFID tag associated with the asset.

Arrangement for monitoring an asset including an interior sensor system arranged on the asset to obtain information about contents in the interior of the asset, a location determining system arranged on the asset to monitor the location of the asset and a communication system arranged on the asset and coupled to the interior sensor system and the location determining system. The communication system operatively transmits the information about the contents in the interior of the asset and the location of the asset to a remote facility. The interior sensor system may include at least one wave transmitter arranged to transmit waves into the interior of the asset and at least one wave receiver arranged to receive waves from the interior of the asset. A processor may be provided to compare waves received by the wave receiver(s) at different times or analyze the waves received by the wave receiver(s).

An identification system is provided for identifying a plurality of randomly aligned object-based transponders (18, 20, 22) passing through a predetermined reading volume. A reader (10) includes multiple transmitting and receiving antenna arrays (12, 14, 16) which are arranged sequentially to transmit interrogating and energizing fields (29) into the reading volume, with each energizing field having a different polarisation. Each transponder (12, 14, 16) is arranged to be powered by at least one of the interrogating and energizing fields, and includes a short term memory module (30) which is arranged to record the successful transmission or otherwise of the identification signal of the transponder (20) and to retain the record in the absence of a power supply to the transponder. The short term memory module has a retention time longer than any predicted interruption of power supply to the transponder via one of the energizing fields within the reading volume. The minimum memory retention time is typically the time period taken for the sequential transmission of all but one of the interrogating and energizing fields (29) during an interrogation cycle.

A system and method for collecting data relating to the parts of a vehicle and using such data to determine if the vehicle can be operated. The system entails the deployment of a plurality of radio frequency identification tags on or within various parts of the vehicle that are capable of issuing radio frequency signals containing data related to each corresponding part. A radio frequency transceiver capable of interfacing with and receiving data stored within each tag operates in conjunction with a central processor unit capable of analyzing the data from each tag and determining whether the vehicle needs parts to be replaced or can be operated with its existing set of parts.
