LOW-ENERGY DETECTION OF A TRANSPONDER BY MEANS OF READ UNIT AND A SYSTEM FOR IDENTITY DETERMINATION AND/OR AUTHORIZATION DETERMINATION, OPTIONALLY IN THE FORM OF A LOCKING SYSTEM
First Claim
1. Read unit (100), e.g. RFID or NFC read unit (100), comprising:
- at least one wireless interface (102, 104, 106;
102, 105), which is designed to generate, in at least one coupling operating state of the read unit, at least one of an electrical alternating field and a magnetic alternating field and an electromagnetic radiation alternating field, to be able to couple inductively or/and capacitively or/and electromagnetically to a transponder (50), if appropriate an RFID or NFC transponder (50), in an assignment region;
a controller (108), which is designed or programmed to respond in the coupling operating state, by means of the wireless interface, to a coupled transponder (50), to carry out a data communication comprising at least one of reading out at least one data value from the transponder and receiving at least one data value sent by the transponder and sending at least one data value to the transponder, or/and at least in the sense of detecting the presence of the coupled transponder; and
an electrical energy supply (120), which supplies the controller and the wireless interface with electrical operating energy;
characterised in thatin at least one idle operating state of the read unit (100), at least the wireless interface (102, 104, 106;
102, 105) is switched off, so that the electrical energy consumption of the wireless interface is at least reduced; and
in the coupling operating state of the read unit (100), the wireless interface (102, 104, 106;
102, 105) is switched on, so that a transponder (50) in the assignment region can couple inductively or capacitively or electromagnetically to it; and
that the controller (108) is designed or programmed to switch automatically between multiple operating states, including the idle operating state and the coupling operating state.

Abstract
Among others, the invention relates to a method and a system for controlling a system for receiving a wireless data transmission between at least two components (12, 100, 50), wherein at least one wireless interface (102, 112) can be activated, or is activated, for wireless data transmission. According to the invention, a first component (100) monitors an environment for the occurrence of at least one predefined change and/or for the occurrence of at least one predefined feedback from the environment. Once such a change, or feedback, has occurred, a wireless interface (102) is activated for the wireless data transmission, and optionally for the energy supply of a second component (50) via the wireless interface. The predefined change or feedback is caused particularly in that the second component (50) is returned to the environment. The system may be a system (10) for determining the identity and/or authorization, such as a locking system. The first component (100) may arrange an interaction between the second component (50) and a further component (12), which, for example, is associated with a target mechanism.

-
a first unit (12), which may be associated with the destination device, and which has a determination device (14) which is designed to determine, on the basis of a preferably encrypted or/and bidirectional data exchange via a first wireless interface (16, 18) of the first unit with a second unit (100), an identity or/and an authorisation, the first wireless interface being designed for wireless data exchange over a first range; at least one second unit (100) which is associated with the first unit (12), and has a notification device (108), which is designed to notify to the determination device (14) of the first unit (12) an identity or/and an authorisation, on the basis of existing identification data or/and authorisation data and of the data exchange which is carried out via the first wireless interface and a second wireless interface (110, 122) of the second unit over the first range; characterised by at least one portable ident medium (50), which carries at least identification data and has an ident medium wireless interface (52, 54), which is designed for wireless readout or transmission over a second range at least of the identification data or of identification data or/and authorisation data which is supplied on the basis of this identification data by a determination device (56) of the ident medium in the case of a positive determination of an identity or/and authorisation; the notification device (108) of the second unit (100) also being designed to receive at least the identification data or/and authorisation data of the ident medium via a third wireless interface (102, 104, 106;
