ABSTRACT:
Disclosed is an arrangement for determining a chronological acceptance of spaced-apart devices, comprising at least one transmitter unit which is disposed on each device and from which a signal that identifies said device and has a predefined range can be transmitted. Several personal apparatuses are provided that are to be carried by one respective person and are fitted with a receiver for the signals and a device memory for storing data contents of the emitted signals during a given interval. The range of each transmitter unit defines a respective transmission range. The transmission range and a receive sensitivity of the receiver are adjusted to each other in such a way that no data can be received if the device is located outside a typical zone of attention or perception of humans relative to the personal apparatus carried by the person.
