Multiplexer as a Position Sensor: How?

Purpose:
Create a position sensor using LEDs.
Goal:
Increase or decrease a pulse width in response to direction of movement.

Chips Involved:
1) Clock.
2) 2x DM74150 (16x1 Multiplexers.)
3) 2x SN74193 (4-bit Binary Counters.)
4) 1x SN74LS112 (Negative Edge Master Slave JK Flip-Flop.)
5) 1x SN74LS122 (Retriggerable Monostable Multivibrator)
6) 2x 7404 (Hex Inverter {Technically, I only need one chip.})
7) 1x 7408 (4 x 2 input AND gates)

In order to sum up what I've already concluded... I'm looking for an incremental encoder.
I just need help figuring out the flow of data. What is happening first, second, third, etc.

I hope that helps explain what I need help with. Again, I would be most grateful for anybody's help.

I have done enough preliminary research to have a basic idea of how things are supposed to work. However, I'm trying to understand the underlying principle of operation (stated above)

Thank you

Hello Allan,

Can you post the circuit diagram of the said project? It is very important to know how the components are connected in order to determine the flow of data.

Frank,

Yes, Thank You.

The LEDs will constantly be transmitting. They look for a blocked path.
When it moves to the right it will produce a square wave from 0% - 100% duty cycle.
When it moves to the left it will go from 100% - 0% duty cycle.

I am understanding that there are two channels. Based on which channel lead/lags the other...

My main question is that... What Feeds What?
1) Does the up counter (74193) feed the multiplexer (74150) as a switch? Therefore, selecting that LED.
2) Does the position of the blocked LED translate into a binary code? Therefore, selecting the condition of the multiplexer as a whole.

Asked another way:
1) Does the (74193) feed the binary selection to the multiplexer for the positions?
2) Or does the (74150) feed the counter with it's corresponding binary number?

The process as I understand it:
1) Clock Feeds Counter.
2) Counter counts up and outputs a binary number.
3) The binary number is fed to the (74150). Therefore, selecting the LED position.
4) Multiplexer outputs it's data.
5) Data enters the (74LS122)... and I'm not really sure what happens here.
6) Some signal runs back to the counter, multiplexer, and a JK Flip Flop (74LS112).
7) I believe this triggers the condition of looking at either multiplexer and determining which LED was blocked before.
8) Once it determines what way the blocked LED is traveling... it "okays" the data and says to increase/decrease your duty cycle.

Thank You

Solved.
I figured it out.
Thank you.
