Patent Images
1. A method for controlling light sources, the method comprising:
- providing an analog input signal at an analog input of a control circuit;
operating the control circuit to provide analog output signals at each of a plurality of analog outputs according to mappings embodied in the control circuit, the mappings relating values of the analog input signal to corresponding values of the analog output signals; and
applying the plurality of analog output signals to drive a corresponding plurality of light sources;
wherein, for each of the analog output signals, the mapping is such that changing the value of the analog input signal within a range causes the analog output signal to vary according to a profile determined by the mapping.

Abstract
The invention provides a system of generation of multi-channel analog output signals, from a single analog input signal, and the controlled activation of peripheral devices responsive to the multi-channel analog output signals. A single-channel to multi-channel analog-to-analog converter is provided to convert the single analog input signal to multiple output channels. Uni-directional coupling is used for coupling and mixing the multi-channel outputs and transferring the mixed outputs to a data bus. Signals on the data bus are used to drive the multiple peripheral devices.
