Abstract

A method has been proposed to provide multipath user feedback at graphics workstations used in semiconductor processing operations. The proposal suggests the incorporation of two audio stereophonic paths or four quadraphonic paths into the workstation. At the dual-headed graphics workstation 1 (Fig. 1) an audio device is required for the alphanumeric display 2 and the graphics display 8. The audio feedback is typically programmed to alert the operator of events, such as initial program load (IPL) sequence, as well as to provide positive feedback, negative feedback and emergency feedback signals. The audio paths proposed to provide this feedback would be activated singularly and/or in parallel. The audio path outputs to be incorporated in the workstation are at the upper left 3, upper right 4, lower left 5 and lower right 6.

Multi-Channel Audio Device for Graphics Workstation

A method has been proposed to provide multipath user feedback at graphics workstations used in semiconductor processing operations. The proposal suggests the incorporation of two audio stereophonic paths or four quadraphonic paths into the workstation. At the dual-headed graphics workstation 1 (Fig. 1) an audio device is required for the alphanumeric display 2 and the graphics display
8. The audio feedback is typically programmed to alert the operator of events, such as initial program load (IPL) sequence, as well as to provide positive feedback, negative feedback and emergency feedback signals. The audio paths proposed to provide this feedback would be activated singularly and/or in parallel. The audio path outputs to be incorporated in the workstation are at the upper left 3, upper right 4, lower left 5 and lower right 6.

The audio signals are to be generated by pre-programmed audio chips which were addressed under the control of the microcode, support software and/or the operator. In the stereophonic configuration the audio signals emanating from the left audio path would be associated with the alphanumeric display 2 (Fig. 1) and/or the keyboard 7. The right audio path would be associated with the graphics display 8 and/or the electronic pointing tablet 9. The appropriate audio signals would be programmed to either the left or right hand audio path depending upon whether they were associated w...
