SYSTEM OF MULTI-CHANNEL ANALOG SIGNAL GENERATION AND CONTROLLED ACTIVATION OF MULTIPLE PERIPHERAL DEVICES
First Claim
1. A system for controlling a group of peripheral devices responsive to variation of a single-channel analog input signal within a range, said system comprising:
- a single-channel to multi-channel analog-to-analog signal converter for converting said single-channel analog input signal to a plurality of analog signals, said range being partitioned into a plurality of sub-ranges, said analog-to-analog signal converter comprising;
a plurality of sub-range signal generators, each of said plurality of sub-range signal generators being responsive to said analog input signal within a sub-range of the plurality of sub-ranges to generate a sub-range analog signal,a data buss having a plurality of buss lines, each of the buss lines being operatively connected to each one peripheral device of the group of peripheral devices for controlling operation thereof, anda unidirectional coupling unit, said uni-directional coupling unit operatively transmitting each of said plurality of sub-range analog signals to at least one of a plurality of buss lines of the data buss and inhibiting any feedback from said buss being transmitted to said analog-to-analog signal converter.

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 buss. Signals on the data buss are used to drive the multiple peripheral devices.
