Owner identification system for electronic equipment, particularly automotive audio equipment
First Claim
1. Owner identification system for electronic equipment, particularly automotive audio equipment, wherein the electronic equipment (1) includesa memory means (4, 5, 6);
- an alphanumeric input means (2) for entering alphanumeric input data into the memory means of the equipment, andan output display device (3) for indicating alphanumeric data,comprising, in accordance with the invention,a non-volatile memory (4) forming part of the memory means;
switch means (S1-S4) for coupling the alphanumeric input means to the non-volatile memory (4) for entering alphanumeric personal recognition data into the memory; and
a recall switch means (S2) selectively(1) connecting the non-volatile memory (4) to the display means for displaying said personal recognition data, or(2) connecting the display means to an output of the electronic equipment for displaying data pertinent to the operation of said electronic equipment.

Abstract
To provide recognition of personal data, for example the registration number of a vehicle in which a car radio is installed, the car radio includes a non-volatile memory (4) which can be selectively connected to a data input arrangement (2) for the electronic equipment (1) to store the registration number therein. A recall switch (S2) is provided to selectively connect the non-volatile memory (4) to the display (3) for displaying the personal recognition data or, in normal operation, to connect the display to the output of the electronic equipment, to display data pertinent to the operation of the electronic equipment, for example the frequency of a tuned station. Two additional memories (5, 6) store, respectively, a predetermined code word and, upon entry from the data entry arrangement, the same code word. Unless the two code words agree,
the recall switch (2) is changed to display only the personal recognition data, for example the vehicle registration. Thus, the vehicle from which a radio has been stolen will be indicated unless the correct code is entered into the additional, and comparison memory. Few electronic components are needed which form part of the electronics of the car radio so that attempts to override the memory or destroy it will result in overall destruction of the electronic equipment.
