US 8,897,637 B2 · Method and arrangement for identifying at least one object

Abstract

The invention relates to a method and an arrangement for identifying at least one object, wherein the object has a connection unit that can be connected to a receptacle unit of a receptacle arrangement, wherein contactless information transfer takes place between the connection unit and the receptacle unit if the connection unit is connected to the receptacle unit, wherein the contactless information transfer is realized as optical information transfer, wherein an optical signal having predetermined optical properties is generated and transmitted by at least one transmitting unit, is transferred via at least one optical transfer path and is received by at least one receiving unit, wherein an evaluation and control unit (14) connected to the receiving unit evaluates the optical properties and/or propagation time properties of the received optical signal and carries out an identification of the object by means of a comparison with stored optical properties and/or by means of a comparison with stored propagation times, wherein the transmitting unit is arranged on the connection unit side or on the receptacle unit side and the receiving unit is arranged on the connection unit side or on the receptacle unit side.

A method for identifying at least one object having a connection unit that can be connected to a receptacle unit of a receptacle arrangement, wherein contactless, optical information transfer takes place between the connection unit and the receptacle unit if the connection unit is connected to the receptacle unit, the method comprising:

generating and transmitting an optical signal having predetermined optical properties using at least one transmitting unit, the predetermined optical properties including a predetermined polarization value;
transferring the optical signal via at least one optical transfer path;
receiving the optical signal with at least one receiving unit;
evaluating properties of the received optical signal with an evaluation and control unit connected to the receiving unit, the evaluated properties including a polarization value;
and
identifying the object by comparing the polarization value with the predetermined polarization value;
wherein the transmitting unit is arranged on a connection unit side or on a receptacle unit side and the receiving unit is arranged on the connection unit side or on the receptacle unit side.

An arrangement for identifying at least one object, comprising:

a receptacle arrangement including at least one receptacle unit;
an object including a connection unit that can be connected to the receptacle unit;
an identification arrangement including at least one transmitting unit, at least one receiving unit, and at least one optical transfer path along which an optical signal is propagated from the transmitting unit to the receiving unit, the at least one optical path influencing propagation time properties of the optical signal in a predetermined manner;
and
an evaluation and control unit connected to the identification arrangement to evaluate propagation time properties of the optical signal received at the receiving unit and to carry out an identification of the object by a comparison of the propagation times of the received optical signal with stored propagation times,
wherein the transmitting unit is arranged on the connection unit side or on the receptacle unit side and the receiving unit is arranged on the connection unit side or on the receptacle unit side.
