Decorative lighting control with a waveform generator

DETAILED DESCRIPTION It is accordingly a general object of the invention to provide an improved waveform generator of width modulated pulses.
Another object of the invention is to provide for the control of discotheque lighting by the use of pulse width modulated waveforms.
Briefly, the invention contemplates an up-down counter means with a plurality of load input terminals for registering an initial count value represented by a received coded combination of signals.
The counter means is unit incremented periodically by pulses fed to a count input while the direction of incrementing is controlled by a signal received at a direction input.
In addition, the counter has two outputs, one indicating a lower desired count value and the other indicating a higher desired count value.
These outputs are connected to the input of a binary means whose output changes state each time a signal is received at its input.
The output of the binary means is not only connected to the direction input of the counter means but also transmits pulse signals whose width is determined by the initial count value represented by a received coded combination of signals.
Other aspects of the invention are concerned with means for generating the coded combination of signals representing the initial count values and with using the width modulated pulses to control the operation of controlled devices such as lights.
Other objects, features and advantages of the invention will be apparent from the following detailed description when read with the accompanying drawing which shows, by way of example, and not limitation, the presently preferred embodiment of the invention.
