Abstract
Abstract The invention permits to a person to make use of a computer or calculator at a distance by using a telephone to communicate with the calculator or computer. The connection may be done directly or by means of any private or public telephone system, combinations of these, and in general by any telecommunication system capable of transmitting the pulses, or tones, generated by the dialing of the telephone, and also the voice. The invention provides the facilities of communication with a computer or calculator by means of the dial of a telephone, sending the numbers and codes of operation using this dial; the verification of the numbers and codes received by the computer by means of the voice in the earphone of the telephone; the reception of the results by means of the voice and a means for the user to recognize when he can send the numbers and when the operation codes, by hearing a special tone.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
69 words
A method of calculation comprising the steps of: communicating with a calculator or computer via a telephonic link by dialing a predetermined telephone number from a telephone; entering numbers and operational codes sent from the telephone via the telephonic link into the calculator or computer, and verifying said numbers and codes by means which reproduce corresponding voice representations of the numbers and codes in the earphone of the telephone;
Claim 2
Independent Claim
69 words
A method of calculation comprising the steps of: communicating with a calculator or computer via a telephonic link by dialing a predetermined telephone number from a telephone; entering numbers and operational codes sent from the telephone via the telephonic link into the calculator or computer, and verifying said numbers and codes by means which reproduce corresponding voice representations of the numbers and codes in the earphone of the telephone;
Claim 3
Dependent Claim
77 words
interpreting different pauses between said numbers and said codes by control means which cause the calculator or computer to interprete them adequately for a calculation, which it is to perform; and comparing calculating results digit by digit, including operational codes, with sequences produced by a voice signal reproduction means which produces a voice signal representation of said calculation results which is applied via an amplifier to the telephonic link and reproduced at the earphone of the telephone.
Claim 4
Dependent Claim
77 words
interpreting different pauses between said numbers and said codes by control means which cause the calculator or computer to interprete them adequately for a calculation, which it is to perform; and comparing calculating results digit by digit, including operational codes, with sequences produced by a voice signal reproduction means which produces a voice signal representation of said calculation results which is applied via an amplifier to the telephonic link and reproduced at the earphone of the telephone.
Claim 5
Independent Claim
260 words
A system for carrying out calculations, the system comprising: an electronic calculator or computer situated at one end of a telephonic link; a telephone located at another end of said telephonic link and which, by its dialing signals introduces into said calculator numbers and codes for a selected calculation and reproduces in its earphone in voice form data sent to said calculator and processed results from said calculator sent back via said telephone link; first control means operatively associated with said calculator for decodifying dialing signals coming from said telephone via said link, said first control means including means for evaluating pauses between these signals and convert then into input information to said calculator in form of numbers and codes; a comparison device coupled to said first control means, responsive to its information output and operatively associated with a voice reproduction means for causing voice signals representative of each received digit and each received code, according to the established pauses, to be reproduced in the earphone of the telephone from said reproduction means via said link; and further control means operatively assciated with said calculator for codifying its calculation results and for entering them into a comparison means, which when it establishes identity between the codified calculation results and an accumulation of signals coming from a voice reproduction device under control of synchronism signals received therefrom, produces a signal which modifies the velocity of said voice reproduction device and effects a feed of a voice signal representation of the calculation results to said earphone of said telephone via said link.
Claim 6
Independent Claim
260 words
A system for carrying out calculations, the system comprising: an electronic calculator or computer situated at one end of a telephonic link; a telephone located at another end of said telephonic link and which, by its dialing signals introduces into said calculator numbers and codes for a selected calculation and reproduces in its earphone in voice form data sent to said calculator and processed results from said calculator sent back via said telephone link; first control means operatively associated with said calculator for decodifying dialing signals coming from said telephone via said link, said first control means including means for evaluating pauses between these signals and convert then into input information to said calculator in form of numbers and codes; a comparison device coupled to said first control means, responsive to its information output and operatively associated with a voice reproduction means for causing voice signals representative of each received digit and each received code, according to the established pauses, to be reproduced in the earphone of the telephone from said reproduction means via said link; and further control means operatively assciated with said calculator for codifying its calculation results and for entering them into a comparison means, which when it establishes identity between the codified calculation results and an accumulation of signals coming from a voice reproduction device under control of synchronism signals received therefrom, produces a signal which modifies the velocity of said voice reproduction device and effects a feed of a voice signal representation of the calculation results to said earphone of said telephone via said link.
Claim 7
Dependent Claim
24 words
A system according to claim 2, including means for converting the dialing signals into a new code compatible with that required by said calculator.
Claim 8
Dependent Claim
28 words
A system according to claim 2, including means for codifying signal results obtained from said calculator into a form compatible with signals produced by said voice reproduction means.
Claim 9
Dependent Claim
77 words
A system according to claim 2, including voice reproduction control means in which the produced voices correspond to digits and codes coming from said telephone and said calculator comprise movable means having an exploration velocity and a reproduction velocity, said movable means having at least one synchronization element which permits selection of voice signals by comparison between an accumulation of pulses coming from said at least one synchronization element and signals from said telephone and said calculator.
Claim 10
Dependent Claim
66 words
A system according to claim 5, including means for sensing an identity between a signal coming from said calculator and a signal coming from said voice reproduction means for producing a signal which makes said voice reproduction means reproduce a voice signal corresponding to the code or number as the case may be which the signal from the calculator represents in the earphone of the telephone.
Claim 11
Dependent Claim
72 words
A system according to claim 2, wherein said comparison device comprises means for permitting decodified signals coming from said telephone to be verified when they are compared with the signals coming from said voice reproduction means to establish that there is identity between them, said voice reproduction means, under control of said means for permitting reproducing voice signals corresponding to the respective numbers and codes received via said link from said telephone.
