Identification unit

Abstract

An identification unit including a memory unit operable to store an identification that distinguishes the identification unit from other identically constructed identification units, an ultrasonic receiver, a radiation transmitter, a radiation receiver and a control unit operable to carry out an ultrasound propagation time measurement depending on a synchronization signal received by the radiation receiver and operable to transmit a result with the aid of the radiation transmitter. At least one of a luminous unit and an optical signaling unit is driven via the radiation unit.

1 . An identification unit comprising:
 a memory unit operable to store an identification that distinguishes the identification unit from other identically constructed identification units;   an ultrasonic receiver;   a radiation transmitter;   a radiation receiver; and   a control unit operable to carry out an ultrasound propagation time measurement depending on a synchronization signal received by the radiation receiver and operable to transmit a result with the aid of the radiation transmitter, wherein at least one of a luminous unit and an optical signaling unit is driven via the radiation receiver.   
     
     
         2 . The identification unit according to  claim 1 , further comprising a bistable character display unit operable to display a content to be represented even after an operating voltage has been switched off. 
     
     
         3 . The identification unit according to  claim 1 , wherein the radiation transmitter comprises an electromagnetic radiation transmitter. 
     
     
         4 . The identification unit according to  claim 1 , wherein the radiation receiver comprises an electromagnetic radiation receiver. 
     
     
         5 . The identification unit according to  claim 1 , wherein the radiation transmitter comprises an electromagnetic radiation transmitter and the radiation receiver comprises an electromagnetic radiation receiver. 
     
     
         6 . The identification unit according to  claim 1 , wherein said at least one of said luminous unit and said optical signaling unit is operable to identify a manufacturing batch to be processed preferentially. 
     
     
         7 . The identification unit according to  claim 1 , wherein said at least one of said luminous unit and said optical signaling unit comprises a flashing unit operable to distinguish the identification unit from said other identically constructed identification units at a distance of several meters. 
     
     
         8 . The identification unit according to  claim 1 , wherein said at least one of said luminous unit and said optical signaling unit comprise a first light emitting diode for identifying a manufacturing batch being sought and a second light emitting diode for identifying an urgent manufacturing batch.
