Abstract:
The invention relates to a method for determining the value of an environment variable using raw data from an energetically essentially passive remote-access apparatus. The method comprises obtaining a value of a measurable quantity from said raw data, requesting calibration data from an entity, and determining the value of the environment variable using said calibration data and said value of a measurable quantity. The invention also relates to calibrating a remote-access apparatus that is energetically essentially passive. Measurements for calibration data may be done in the normal life-cycle of the remote-access apparatus, and calibration data may be formed based on these measurements. The calibration data can be divided and stored on different storage devices, and the remote-access apparatus itself may be one storage device. Many remote-access apparatuses may be calibrated in a single run, or calibration may be done for each individual remote-access apparatus. The methods or various parts of the methods may be done with an RFID reader device. The RFID device may be equipped with a sensor determining the reference values of an environment variable, and it may be an integral part of the devices used to handle remote- access apparatuses during their normal life cycle. Calibration data can be stored in a database, and the data-base can be accessed when measuring the environment with a remote-access apparatus.

An improved calibration detection system for use in calibrating an electronic apparatus includes a processor apparatus, an evaluation apparatus, and a connection apparatus. The connection apparatus includes a plurality of leads and is operated by the processor apparatus to internally switch and connect the various leads with various elements of the evaluation apparatus. By enabling all of the leads to be connected at the outset with the electronic apparatus and by internally switching the connections between the leads and the various elements of the evaluation apparatus, the calibration detection system saves time and avoids error in performing a testing protocol.
