After window is all the way up it sounds like the motor turns off. How does it know? What type of device is being used to sense that?

Here’s an extensive article with illustrations about how a power car window works – it works with a series a gears and an electric motor, with safety features.
Most electric car windows have a feature that stops them from going up when something gets caught in the way. This is a safety feature that keeps people safe, and mainly is intended to stop children from getting hurt should they stick their arms out of a window that is going up. When the window pushes against something, more force is registered and when a certain amount of force is noted, the window automatically stops or goes down.
