Abstract
Abstract The device, which may be connected either directly to the computer itself or which may form a part of a remotely located input/output station, includes electronic signal generation circuits for generating a signal indicative of the receipt of data being inputted by a human operator, and an error signal indicative that some error in procedure, particularly data input in the wrong mode has been made. These electronic signals are fed to a loudspeaker to produce an audible output.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
In a data processing system having a computer means for receiving, recording and performing mathematical operations upon data, and input means for receiving said data, said input means being connected between a source of said data and said computer means, said source of data being a humanly operable data transducer producing a plurality of discrete units of input data signal in response to the operation thereof by a human operator, THE IMPROVEMENT COMPRISING input monitor means connected to said input means for generating a humanly sensible data entry signal indicative of the receipt by said computer means of said input data signal from said input means, said humanly sensible data entry signal being produced coextensively in time with said input data signal from said source, such that for each said discrete unit of said input data signal a discrete unit of said humanly sensible data entry signal is produced, whereby said human operator is provided with a confidence check for the receipt of data being inputted to the system.
Claim 2
Dependent Claim
169 words
In a data processing system having a computer means for receiving, recording and performing mathematical operations upon data, and input means for receiving said data, said input means being connected between a source of said data and said computer means, said source of data being a humanly operable data transducer producing a plurality of discrete units of input data signal in response to the operation thereof by a human operator, THE IMPROVEMENT COMPRISING input monitor means connected to said input means for generating a humanly sensible data entry signal indicative of the receipt by said computer means of said input data signal from said input means, said humanly sensible data entry signal being produced coextensively in time with said input data signal from said source, such that for each said discrete unit of said input data signal a discrete unit of said humanly sensible data entry signal is produced, whereby said human operator is provided with a confidence check for the receipt of data being inputted to the system.
Claim 3
Dependent Claim
17 words
The apparatus according to claim 1 wherein said humanly sensible data entry signal is an auditory tone.
Claim 4
Dependent Claim
45 words
The apparatus according to claim 1 wherein said monitor means includes an error signal means for generating a humanly sensible error signal indicative of transmission of data from said source under circumstances when said input means is not in a condition to receive said data.
Claim 5
Dependent Claim
43 words
The apparatus according to claim 1 wherein each of said discrete units of said input data signal comprises an electrical pulse, and each of said discrete units of said humanly sensible data entry signal comprises an auditory tone generated by said monitor means.
Claim 6
Dependent Claim
53 words
The apparatus according to claim 4 wherein said humanly operable transducer comprises a manually operable probe means for producing said electrical pulses in response to manual application of said probe to a solid surface, whereby said probe can be used to produce information in electrical pulse form concerning objects pictorially represented in drawings.
