Abstract: The invention relates to the monitoring of products by means of active radio tags. According to the invention, packagings of products are provided with an active radio tag that detects at least one environmental condition and/or at least one packaging state, and which emits a signal at time intervals, which provides information about a unique identifier and at least one state in which the respective product is found. The signal is picked up by a receiver that extracts the unique identifier and the state information and transmits same together with location information to an external server.

Abstract: An apparatus and a method for generating hoistway information from images of the surface patterns of a hoistway component such as a guide rail sensed by a CCD line camera. The image data are input into a first correlator which uses an incremental position of a new image and an absolute position of a preceding image to generate an estimated position. The estimated position is input into a second correlator and is used to locate the relevant database sector in which the image which was stored in the database during calibration is situated. The second correlator compares the new image with the stored image and determines from the position index of the stored image the absolute position of the elevator car which is transmitted to the elevator control.
