Person identification system
First Claim
1. A system for identifying individuals and controlling access authorization comprising the combination ofa plurality of identification units (T) each associated with and carried by a person and each having stored therein a unique code-set at least including a presence code identifying the carrying person;
- a plurality of object units (O) each associated with an object to which access is selectively permitted or denied;
a plurality of control units (K) having means for recognizing selected codes of said unique code-sets as constituting authorization codes to perform a function at selected object units;
each of said identification units (T), said object units (O) and said control units (K) includes a memory for storing a data set common to all of said units by which all of said units are recognized as belonging to a defined system;
means for establishing bidirectional communication links between said control units (K);
means for establishing a communication link between selected pairs of identification units (T) and object units (O) limited to unidirectional communication from each said identification unit to an associated object unit, communication between identification units (Ts) and between object units (Os) being limited to communication through associated control units (Ks); and
means for establishing a bidirectional communication link between one control unit (K1) and a selected identification unit (T1, T2, . . . Tn), and between said one control unit (K1) and a selected object unit (O1), whereby, in response to communication of an authorization code from an identification unit to said object unit (O1) and recognition thereof by said control unit (K1), a predetermined function at said object unit (0O) is performed.

Abstract
An individual identification system is a modular combination of a person-related first unit with transmittable/receivable storage elements by way of an antenna, the unit operating alone or together with a further unit having an additional, but different, identification part, and a person-unrelated and instead object-related second unit for the interaction between the person and the object and with a control for checking and maintaining the interaction with which units and objects are crosslinked. The person-related first unit is carrier oriented and is permanently or removably located on a use article, e.g., on a key, in a pass, on or in a watch or any other object which changes position with the person and is not coordinate-fixed. The object-related second unit is place-oriented and is at fixed locations (e.g. building doors), or is arranged in fixed manner on moving objects (e.g. vehicles).

7. A method of identifying individual persons and thereby controlling access to objects including the steps of
providing each person with an identification unit (T) to be carried by the person, providing each said identification unit (T) with a memory having stored therein a machine-readable code-set defining at least a unique identification of the person and with means for communicating to object units and control units at least said identification, positioning a plurality of object units at a plurality of locations at which transmissions from identification units are received when persons carrying said identification units are using said identification units on one of said plurality of object units, each object unit having a memory and having a predetermined function associated therewith, providing a plurality of control units each having a memory and having a data processor, storing in the memory of each said identification unit, object unit and control unit a common data set by which said units are recognized as belonging to a defined system, establishing a bidirectional communications link between each said control unit and each other said control unit, and between each said control unit and selected identification and object units, communicating to a control unit an identification received by the object unit which receives the identification from within the predetermined distance, and determining in the control unit functions to be performed at the locations of receiving object units and at object units not receiving identifications as persons move between object units, whereby locations and access authorizations of persons can be determined automatically.
