Device for the authorisation of the use of an apparatus with an actuating unit

Abstract

Abstract For the authorised operation of devices having an actuation unit (1) an operation authorisation circuit is divided into two. Its first part (2) is provided in the actuation unit (1) of the device and its second part (6), interacting with the first part (2), is provided in a codeable external device (5) which is to be attached to an authorised person. Each of the two parts of the operation authorisation circuit have a transceiver (3, 7) for contactless signal exchange between the actuation unit (1) and the external device (5) so that the approach of the external device (5) to the actuation unit (1) establishes the authorisation and its removal ends the authorisation. <IMAGE>
