The invention relates to a device for monitoring physical objects that comprises one or more short-range remote readers, memory elements to be attached to physical objects, and a controller adapted for executing a reading function capable of interaction with the one or more remote readers in order to acquire data contained in adjacent memory elements, and for executing an integrity validation function capable of distinguishing, from the acquired data, individual identifiers particular to each of the memory elements as well as group description data stored in at least some of said memory elements, and of checking the sufficiency of group description data while checking the compliance of individual identifiers with corresponding group description data.

Device and method for checking the integrity of physical objects

The invention relates to a device for monitoring physical objects that comprises one or more short-range remote readers (), memory elements () to be attached to physical objects, and a controller () adapted for executing a reading function capable of interaction with the one or more remote readers in order to acquire data contained in adjacent memory elements, and for executing an integrity validation function capable of distinguishing, from the acquired data, individual identifiers particular to each of the memory elements as well as group description data stored in at least some of said memory elements, and of checking the sufficiency of group description data while checking the compliance of individual identifiers with corresponding group description data.

The invention concerns a device dedicated to the management of data between at least one user mobile station (MS) equipped with a communication module (), stationary terminals () associated with at least one service, and a plurality of mobile service means () equipped with a communication module () and adapted to ensure said service. Said device comprises i) first control means () designed to be implanted in the user mobile station (MS) and adapted, upon the user's instruction to generate a primary request including data defining a request for obtaining a service selected at a terminal () installed proximate to the mobile station (MS) and associated with the service, ii) second control means () adapted, upon reception of a primary request, to generate a secondary request including data defining a request for ensuring the selected'service at the terminal (), and iii) third control means () implanted in each of the mobile service means () and adapted, upon reception of a secondary request by the associated communication module (), to order stoppage of the associated mobile service means () at the terminal (), so as to ensure the service requested by the user of the mobile station (MS).

Device and method for managing data between communication facilities to obtain a mobile service

The inventive information distributing system (), in particular for railway stations or airports, comprises a control unit () delivering information items selected according to a first key value to a main distributor (), a short-range communications relay () for establishing connections with mobile terminals (). Said control unit comprises a relay interface and a control module carrying out a function of general distribution to the distributor, an inventory function for interacting with the terminals by storing state data received therefrom and by setting a second key value according to a state data sub-group and a particular distribution function for transmitting the information items selected according to the second key value to the terminals having the second sub-group state data.

System for information contextual distribution simultaneously in a public and individual mode

An access interface (Bai) allows access to a context-sensitive service to a user portable set (Ui) according to a chosen geographical coverage. A mobile station (SMi) distributed in the access interface area of coverage is equipped with communication means to establish short-range radio frequency communication within a chosen perimeter. The user portable set (Ui) is equipped with short-range radio frequency communication means paired with those of the mobile station to establish the said short-range radio frequency communication within the chosen perimeter. The user portable set (Ui) communicates with the mobile station (SMi) and the access interface (Bai) to access the said context-sensitive service (Si) which is adapted according to the position and/or identity of the user.
