Wave Function Collapse using faulty recording devices.

TL;DR Summary

Effectiveness of faulty observational devices during the Double Slit Experiment and the Wave Function Collapse.

Hey there!
I have two questions regarding the Double Slit Experiment and the Wave Function Collapse.

How effective does a measuring device have to be to cause a collapse? As in, say that every second the device has a 50% chance to turn off or on for one second, does the collapse still occur when the device has shutoff?
Similarly, suppose an observer has been awake for a few days and perhaps even on a drug trip that is rendering them in and out of consciousness, is there a threshold in which the observation does not occur?

Thank you for your time!

does the collapse still occur when the device has shutoff?

No.

It's not just faulty measuring devices, a device to detect a particle may simply not be 100% effective. E.g. if only 50% of particles were detected (at one slit or the other) and 50% went undetected, then these 50% undetected particles, between them, would form a double-slit interference pattern; and, the detected particles would form two separate single-slit patterns (assuming the detection did not significantly influence this). The total pattern, therefore, would be this combination of patterns.

Oh wow, fascinating! <3

Silly me, it didn't occur to me that I have to rotate by 90 degrees.
