Can't figure out where and how to make a new Thread for my object.

I've made a quite CPU expensive object in which I would to make a new Thread to make things a little bit lighter for Max. I tried copying some things from the tutorials in to It would be nice if somebody my object but I couldn't manage to get it working.

It would be nice if somebody could take a look at my code:

import com.cycling74.max.*;
import java.util.*;

public class ynsDataSampling extends MaxObject implements Executable {

    private boolean isRecording = false;
    private List storage = new ArrayList();
    private double time = -1;
    private double lastTime = 0;
    private MaxClock clock;
    private int curPbIndex = 0;

    public ynsDataSampling() {
        declareIO(2,1);
    }

    public void record(boolean b) {
        isRecording = b;
        if (b) {
            stop();
            storage.clear();
            time = -1;
        } else {
            double currentTime = MaxClock.getTime();
            lastTime = currentTime - time;
        }
    }

    public void list(Atom[] value) {
        if (getInlet() == 1 && isRecording) {
            double currentTime = MaxClock.getTime();
            double delta;
            if (time == -1) {
                delta = 0;
            } else {
                delta = currentTime - time;
            }
            storage.add(new ListWrapper(value, delta));
            time = currentTime;
        }
    }

    public void start()    {
        if (isRecording) {
            record(false);
        }
        curPbIndex = 0;
        clock = new MaxClock(this);
        clock.delay(0);
    }

    public void execute() {
        try {
            outlet(0, storage.get(curPbIndex).dataList);
            if (curPbIndex < (storage.size() - 1)) {
                clock.delay(storage.get(curPbIndex + 1).deltaTime);
                curPbIndex++;
            } else {
                curPbIndex = 0;
                clock.delay(lastTime);
            }
        } catch (IndexOutOfBoundsException c) {
        }
    }

    public void stop() {
        if (clock!= null) {
            clock.unset();
            clock = null;
        }
        curPbIndex = 0;
    }

    public void deltalist() {
        double[] deltaList = new double[storage.size()];
        for(int i=0; i
            deltaList[i] = storage.get(i).deltaTime;
        }
        outlet(1, deltaList);
    }
}

class ListWrapper {
    public Atom[] dataList;
    public double deltaTime;

    public ListWrapper(Atom[] dL, double dT) {
        dataList = dL;
        deltaTime = dT;
    }
}
