Abstract
Abstract The method and apparatus for the automatic questionnaire presentation and statement compilation involves the use of a magnetic tape playback unit carrying a multi-track magnetic tape pre-recorded to provide spoken questions for an individual, teletype statement printout signals, binary question identification code signals, binary next question search code signals for yes, no, and undecided individual responses, and operating control signals for tape speed and timing and for start and stop of audio and teletype signals. The electrical outputs of the playback unit are connected to a digital logic control unit to which also is connected the electrical outputs of a patient response unit. The logic control unit is programmed to control the playback unit to select from a questionnaire on the tape questions corresponding to individual responses to previous questions, and to select from a plurality of modulating codes on the tape, each representing a statement, appropriate codes for modulating a teletype unit to provide printout of statements pertinent to the individual responses.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
125 words
The method of presenting a spoken branching questionnaire to an individual, comprising a. pre-recording a magnetic tape to provide 1. audio frequency intelligence signals representing branching questions for an individual, and 2. electric teletype modulation signals representing statements corresponding to alternative responses of an individual to the questions, b. playing back the tape on a playback device to present spoken questions to the individual, and c. utilizing the response of the individual to the question to operate the playback device to feed appropriate signals of the electric teletype modulation signals to a teletype to print out a statement corresponding to the individual''s response to the question and to play back to the individual a next question corresponding to the patient''s response to the preceding question.
Claim 2
Independent Claim
125 words
The method of presenting a spoken branching questionnaire to an individual, comprising a. pre-recording a magnetic tape to provide 1. audio frequency intelligence signals representing branching questions for an individual, and 2. electric teletype modulation signals representing statements corresponding to alternative responses of an individual to the questions, b. playing back the tape on a playback device to present spoken questions to the individual, and c. utilizing the response of the individual to the question to operate the playback device to feed appropriate signals of the electric teletype modulation signals to a teletype to print out a statement corresponding to the individual''s response to the question and to play back to the individual a next question corresponding to the patient''s response to the preceding question.
Claim 3
Dependent Claim
93 words
electric teletype modulation signals representing statements corresponding to alternative responses of an individual to the questions, b. playing back the tape on a playback device to present spoken questions to the individual, and c. utilizing the response of the individual to the question to operate the playback device to feed appropriate signals of the electric teletype modulation signals to a teletype to print out a statement corresponding to the individual''s response to the question and to play back to the individual a next question corresponding to the patient''s response to the preceding question.
Claim 4
Dependent Claim
