Abstract

A multi-function information system utilizing a specialized modular information library is disclosed. In its preferred embodiment, the system is applied to the problem of teaching technicians the theory of specific apparatus and providing a tool to aid in the location and correction of malfunctions of the apparatus. In such an application, the system may comprise a video playback system and a video-cassette library containing a description of how the apparatus operates and malfunction correction procedures. Special procedures are employed in constructing the library to assure that the teaching and malfunction correction times are minimized.

Claims

1. The method of repairing apparatus by utilizing a maintenance system which includes, (a) data storage means wherein coordinated audio and visual data comprising visual and audio presentation of maintenance procedures relate to said apparatus are stored, (b) audio reproduction and visual display means, and (c) data retrieval means permitting the selective recovery of said stored data to activate said audio reproduction means and said visual display means, the method comprising the steps pf:

1. utilizing a symptom of a malfunction of said apparatus for the selective recovery of said stored data by index in said data retrieval means to the beginning of one of said maintenance procedures;

2. activating said audio reproduction meas and said visual diaplay means in response to said indexing so as to generate a visual display and audio description of the selected maintenance procedure for use in correcting said malfunction.
