Audio Level Control for Self-Service Computer Terminals

       This article describes a system which maintains a
comfortable volume level for users of self-service computer terminals
in variable environments.

      The system will support two software packages: Infowindow  and
Audio Video Computer (AVC).  Dependent upon which software package is
utilized, the system can support still frame pictures, full motion
video and graphics to guide the user through the selection process.
With video and audio, a complete discription of the products or
services being offered can be achieved.  The customer interface is
through the touchscreen, keyboard, and card reader.  A receipt is
issued for each transaction.

      A personal computer (PC) is utilized as the system unit and
supports Infowindow or AVC to provide interactive display capability.
Video and audio are furnished by a video disc player or other direct-
access storage device (DASD) under the control of the PC unit.  Audio
amplifiers and associated speakers provide high quality audio output.

      Ancillary functions are added to the above to provide a modem,
automatic audio level control, proximity detection, tamper switch,
and remote off/on functions.  Individual functions or combinations of
functions can be added or deleted to form unique configurations.

      The audio level control circuit device for self-service
computer terminals is depicted in Fig. 1.  The device is intended to
maintain a comfortable audio level for the user while some variation
in ambient noise level may be encountered.  To further illustrate the
application, a drawing of the product in which the device is utilized
is shown in Fig. 2. ...
