Abstract
Abstract An extensible coded carrier provided with a binary code, consisting of a number of binary code elements mounted, for example, on a printed-circuit board. The code is capable of being extended to include an element which is analogue in principle, for example, a resistor. If desired, the analogue code element may be converted into a digital code element with the aid of a discriminator. The extended code may be used as an address to address a treatment programme.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
233 words
In a system for the treatment of electronic devices or elements wherein a particular treatment program is selectable upon the occurrence of a particular coded address, said system including at least one carrier of the type such as a printed circuit board, the improvement comprising: a pair of input terminals located on said carrier; a plurality of galvanic contacts being disposed on said carrier; means for connecting a first of said terminals to a predetermined number of said galvanic contacts; means for connecting the second terminal to a predetermined number of galvanic contacts which are not connected to said first terminal, each of said terminals being identified with a digital logical value, one of said terminals being associated with a logical "1" and the other terminal being associated with a logical "0", said arrangement of galvanic contacts being ordered in accordance with a predetermined pattern so that a predetermined digital coded number corresponds to said ordered arrangement of galvanic contacts; a further galvanic contact being disposed on said carrier; an electrical impedance element being connected between said further galvanic contact and one of said input terminals, said impedance element forming an analog code element for extending said binary coded arrangement of galvanic contacts, sensing means responsive to said digital coded arrangement of galvanic contacts and said analog code element for providing an address for selecting a corresponding treatment program of said treatment system.
Claim 2
Dependent Claim
233 words
In a system for the treatment of electronic devices or elements wherein a particular treatment program is selectable upon the occurrence of a particular coded address, said system including at least one carrier of the type such as a printed circuit board, the improvement comprising: a pair of input terminals located on said carrier; a plurality of galvanic contacts being disposed on said carrier; means for connecting a first of said terminals to a predetermined number of said galvanic contacts; means for connecting the second terminal to a predetermined number of galvanic contacts which are not connected to said first terminal, each of said terminals being identified with a digital logical value, one of said terminals being associated with a logical "1" and the other terminal being associated with a logical "0", said arrangement of galvanic contacts being ordered in accordance with a predetermined pattern so that a predetermined digital coded number corresponds to said ordered arrangement of galvanic contacts; a further galvanic contact being disposed on said carrier; an electrical impedance element being connected between said further galvanic contact and one of said input terminals, said impedance element forming an analog code element for extending said binary coded arrangement of galvanic contacts, sensing means responsive to said digital coded arrangement of galvanic contacts and said analog code element for providing an address for selecting a corresponding treatment program of said treatment system.
Claim 3
Dependent Claim
63 words
The system of claim 1, wherein said treatment system is a universal measuring apparatus, said program is a predetermined measuring program and the system includes an analog-to-digital converter for converting the analog value of the impedance to a digital coded value, the combined coded number of said galvanic arrangement and converted impedance value providing an extended digital coded value for addressing said program.
