| Title: |
Portable Control Unit for Theater, Television, and Film Lighting Control Systems |
| Abstract: |
A self-contained portable unit for use with theater and television dimming
systems and, in particular, with one control console of a
microprocessor-based lighting control system having a data display device
such as a CRT. The unit includes a digitizer tablet, a stylus and an
overlay to be placed on the tablet. The keyboard of the console is
reproduced in the overlay in the form of keys replicating indicia printed
or silk-screened on the overlay. An area is also provided on the overlay
for placement of the designer's lighting pattern layout. Lighting pattern
information and lighting levels are entered into the system by the unit by
touching the stylus to specific points in the layout and to specific key
indicia selected by the user. Initially, each symbol on the lighting
pattern layout is defined by using the unit or the console to enter the
channel, the light level in each channel, cueing instructions, or other
information which the symbol represents into the system. Thereafter, by
touching the stylus to the symbol when it is in position on the overlay,
the complete line or list of information represented by the symbol is
immediately displayed on the CRT screen without the necessity of rekeying
all the symbol definitional information into the system.
