Abstract: A method and apparatus for providing mass storage of vocal information by means of a digital communication system for use with a training simulator is disclosed. Unlike prior art analog records and playback systems, such as tapes, etc., the inherent advantages and flexibility available with respect to a digital system including randomly accessible voice messages, convenience of editing the stored data, and management and control by the computational system of the training simulator are available with the present invention. In general, the system of this invention comprises an input device, such as a microphone (30), an encoder (54) for encoding the analog information from the microphone (32) to digital format, a digital processing controller or computer (20) for processing the digital communication data in response to a stored program such that it is suitable for use with the computational system, and a mass storage media (38) for storing the processed digital data.

Abstract: A system that utilizes a light pen for changing the alphanumeric value of certain information that is displayed on the screen of a cathode ray tube. Certain parameters and their alphanumeric values are displayed on the CRT screens. A row of dots or other characters are drawn on the CRT screens next to the listed parameters. When the operator of this invention touches one of the dots or other characters with a light pen, the parameters next to the dots or characters will be identified and the alphanumeric value of that parameter will be either incremented or decremented at a fast or slow rate, depending upon the position of the dot in the array. Various types of arrays may be utilized.
