Abstract
Abstract A programming device, comprising an integrated circuit which is provided with an envelope and a coding matrix which comprises code conductors and a code generator which is connected thereto so as to supply each code conductor with its own sub-code. The integrated circuit is coupled to the coding matrix so as to receive a code signal programmed in the coding matrix.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
68 words
A device comprising code-matrix means for generating a fixed code signal comprising a plurality of code conductors, a code generator means having an input means for receiving locally generated identical clock pulses and an output means coupled to said conductors for supplying to each of said conductors a subcode respectively, and a circuit means coupled to said matrix means for receiving from said matrix means said code signal.
Claim 2
Independent Claim
68 words
A device comprising code-matrix means for generating a fixed code signal comprising a plurality of code conductors, a code generator means having an input means for receiving locally generated identical clock pulses and an output means coupled to said conductors for supplying to each of said conductors a subcode respectively, and a circuit means coupled to said matrix means for receiving from said matrix means said code signal.
Claim 3
Dependent Claim
19 words
A device as claimed in claim 1, wherein the code generator means and the circuit means are integrally formed.
Claim 4
Dependent Claim
98 words
A device as claimed in claim 1, further comprising connection terminal means coupled to the code matrix for receiving the sub-codes, the circuit means comprising one code signal output terminal means for providing the code signal in series, a switching device provided with a control input, said switching device being coupled between the connection terminals and the code signal output terminal, the code generator being coupled to the control input, said switching device comprising means for coupling the connection terminals successively to the code signal output terminal under the control of a signal supplied by the code generator.
Claim 5
Dependent Claim
113 words
A device as claimed in claim 1, wherein the circuit means comprises a plurality of output terminals which correspond to the number of bits of the code signal, and further comprising connection terminals means coupled to the coding matrix for receiving the sub-codes, storage elements provided with a plurality of control inputs which corresponds to the number of bits of the sub-code, said elements being coupled to each connection terminal, the said storage elements being coupled to the output terminals and comprising means for supplying the output terminals simultaneously with the bits of the sub-codes which are successively applied to the connection terminals, and a control signal generator coupled to said control inputs.
Claim 6
Dependent Claim
16 words
A device as claimed in claim 1 further comprising a receiver of a selective paging system.
