Method and device for the detection and identification of objects, secure containers and systems which are provided with said device, and objects adapted for same
First Claim
1. A method for the detection and identification of an object provided with identification means and wireless transmission means, the object being located close to one receiver module among a plurality of receiver modules, the method comprising the steps of:
- electromagnetically coupling the wireless transmission means of the object with a first of a plurality of fixed antennae each associated with a receiver module among said plurality of receiver modules; and
switching, in an analogue manner, between each of the fixed antennae and a secondary fixed antenna common to all of the fixed antennae such that the common secondary fixed antenna is electrically connected to each of the fixed antennae of each receiver module in succession,wherein the common secondary fixed antenna is electromagnetically coupled to a primary fixed antenna connected to a reader module configured to read identification data originating from the identification means.

Abstract
A method of detecting and identifying an object (O) which is provided with identification elements (Io) and wireless transmission elements (Ao), the object being disposed close to one receiver module (Mi) from among a plurality of receiver modules (M1, . . . , Mi, . . . , Mn). The inventive method includes: (i) an electromagnetic coupling between the object'"'"'s wireless transmission elements (Ao) and a fixed antenna (Ai) which is associated with the aforementioned receiver module (Mi); and (ii) an electrical coupling between the fixed antenna (Ai) of the receiver module (Mi) and a secondary fixed antenna (3) which is common to all of the fixed antennas (A1, Ai, . . . , An) of the receiver module. Moreover, the common secondary fixed antenna (3) is electromagnetically coupled to a primary fixed antenna (2) which is connected to a read module (4) that is designed to read the identification data originating from the identification elements (Io).
