Gear-driven automated window or door system

A device comprising:

• a frame and a slidable window that is slidably mounted within the frame;
• wherein the frame comprises a first open channel with two parallel walls that retain the slidable window as it slides in the frame;
• a first motor mounted on the slidable window;
• a controller that controls the operation of the first motor;
• a first gear driven by the first motor;
• a first gear track retrofitably mounted to a surface of one of the two parallel walls of the first open channel;
• wherein teeth of the first gear mesh with teeth of the first gear track;
• wherein rotating the first gear in a first rotational direction moves the slidable window in a first linear direction as the first gear walks along the first gear track;
• wherein rotating the first gear in a second rotational direction moves the slidable window in a second linear direction as the first gear walks along the first gear track;
• wherein the device further comprising one or more sensors;
• wherein the controller is adapted to communicate with a user's smart device running an app;
• and
• wherein the controller and smart device running an app are configured to provide (a) user control of the slidable window, (b) notice to the user when the slidable window has been automatically moved in response to a signal from at least one of the one or more sensors and (c) warnings to the user in response to a signal from at least one of the one or more sensors.
