Hololens falls asleep if moveless

Question

In my app I need to measure a camera data if the glasses are moving or not. I get the data with:

quaternions["x"] = Camera.main.transform.rotation.x;
quaternions["y"] = Camera.main.transform.rotation.y;
quaternions["z"] = Camera.main.transform.rotation.z;
quaternions["w"] = Camera.main.transform.rotation.w;
quaternions["tx"] = Camera.main.transform.position.x;
quaternions["ty"] = Camera.main.transform.position.y;
quaternions["tz"] = Camera.main.transform.position.z;

If I move the glasses, the app works fine. But if I leave the glasses on the table, then after 4 minutes the glasses disable display and the code returns last stored data. Even if the charge cable is plugged in. If I press enable button on the glasses, the display is on again and the data is also right.

Is there some possibility to prevent the glasses falling asleep?

According to comment of @Kay, the solution is adding the line:

Screen.sleepTimeout = SleepTimeout.NeverSleep;

NOTE: this solution works if you use MixedRealityToolkit-Unity because it needs:

using UnityEngine;
