Patent ID: 8368511

Claim:
A method for monitoring a package for storage and/or transport of at least one item, the method comprising: monitoring at least two physical properties of an time by at least two sentinel sensors, where at least one of the sensors is connected to a memory module storing predefined or measured data; receiving time- and temperature-dependent measurement data from the sentinel sensor by a determining module; determining a current status by the determining module by applying the measurement data to trend data from the memory module containing data representing one or more predefined temperature-depended shelf-life trends as the trend data; permitting a reading unit for receiving data from the sentinel sensors to retrieve current status data corresponding to the current status determined by the determining module via a communications interface to a transmission unit, which is a transponder including an integrated circuit coupled to an antenna and which executes a decision about a selection of data to be transmitted; and taking the decision by a logical node about a selection of data, which is transmitted from the transmission unit to a receiving unit, wherein the transmission unit comprises alert and sensor status data for a selection desired and made by a user and program instructions for relaying communications between the receiving unit and the sensor and is adapted to operate according to a mobile communication standard.
