Abstract
Decorative lighting control is effected by a waveform generator which employs an up-down counter that is alternately stepped in up and down directions. Each time the counter reaches either the maximum or minimum count, it is loaded with a count value representing the width of a pulse to be generated and the direction of the count is changed. A source of the count value is provided by utilizing another up-down counter. The width modulated pulses which result are used to control lighting devices.
Claims16
A waveform generator comprising:
- a multi-stage up-down counter means, said up-down counter means having a plurality of load input terminals connected to the stages for registering a desired initial count in response to a coded combination of signals received in parallel, a count input for unit changing the registered count in response to a received pulse, a direction input for controlling the direction of the counting in response to the level of a received signal, an upper output for emitting a signal whenever the registered count reaches a given upper value, and a lower output for emitting a signal whenever the registered count reaches a given lower value;
- loading means for controllably feeding a coded parallel combination of signals representing a desired initial count to said load input terminals;
- a pulse source connected to said count input and operating at a given frequency;
- and binary means for emitting a signal having a first level when in a first state and emitting a signal having a second level when in a second state, said binary means having an input for changing the state of the binary means upon receipt of a signal from one of said outputs and being connected to said upper output and said lower output, and said binary means having an output for controlling said loading means and for emitting a width modulated waveform signal.
A decorative lighting control comprising a discotheque lighting means, a multi-stage up-down counter means, said up-down counter means having a plurality of load input terminals connected to the stages for registering a desired initial count in response to a coded combination of signals received in parallel, a count input for unit changing the registered count in response to a received pulse, a direction input for controlling the direction of the counting in response to the level of a received signal, an upper output for emitting a signal whenever the registered count reaches a given upper value, and a lower output for emitting a signal whenever the registered count reaches a given lower value;
- loading means for controllably feeding a coded parallel combination of signals representing a desired initial count to said load input terminals;
- a pulse source connected to said count input and operating at a given frequency;
- and binary means for emitting a signal having a first level when in a first state and emitting a signal having a second level when in a second state, sais binary means having an input for changing the state of the binary means upon receipt of a signal from one of said outputs and being connected to said upper output and said lower output, and said binary means having an output for controlling said loading means and for emitting a width modulated waveform signal, said lighting means being coupled to the output of said binary means.
