Abstract: A system for producing a location-based inventory of objects each furnished with an RFID transponder (24) designed to interact with an RFID reader/interrogator (30) and placed at different locations of a warehousing structure (10) including a plurality of rows (16A-16C) supported by vertical uprights (18A-18D). Each of the uprights of this warehousing structure is furnished at each of the rows with an RFID location transponder (26) and a processor (30; 32) to produce a location-based inventory of the objects present on the warehousing structure according to the information received from the transponders.

Abstract: This invention relates to a mobile device for collecting and validating collected articles, each equipped with a transponder and including rollers for moving along a runway in a predetermined path, a horizontal beam for receiving the articles collected during this displacement one by one, a radio-frequency interrogator for obtaining identifying information on each of the articles collected by the device and a comparator for comparing the identifying information obtained with references relative to a determined order for articles and thus for validating the collected articles as they are collected along the runway.

Abstract: A secure system for tracking goods loaded on a delivery vehicle having a driver's cab and at least one container, said driver's cab being provided with a first RFID transponder disposed on any wall of said cab, and each of the containers is provided with at least two RFID transponders, one of which is disposed on any wall of said container and the other of which is disposed on each of the delivery doors of said container, each of said RFID transponders being designed to co-operate with a RFID reader/interrogator integrated into a mobile telephone of the driver of the vehicle, said mobile telephone being in communication with a management server via a mobile communications network.

Abstract: The invention provides apparatus for detecting articles (1) by implementing radiofrequency type means, the apparatus comprises a transmitter member (4) for transmitting a signal at given frequency and given amplitude, a receiver member (5) for receiving the transmitted signal, and an RLC type element (3) fitted to each article (1). The transmitter member (4) transmits sequentially a plurality of signals (A, B, C, D) at respective frequencies. The articles (1) are distributed by article type and each article of a given type is fitted with an RLC type element (3) that is resonant at a respective frequency.
