Description:TECHNICAL FIELD
[0001] The present disclosure relates to the field of door and window closures. In particular, the present disclosure provides an automatic window shade facilitating control of air and light passage through window of a room.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, or that any publication specifically or implicitly referenced is prior art.
[0003] Physical and continuous monitoring of environmental conditions outside a room and ambient conditions inside the room for opening and closing of doors and windows is a tedious task. To avoid the hassle, occupants of the room often choose to keep the doors and windows closed on all occasions, thus prohibiting circulation of fresh air inside the room. Therefore it would be beneficial to devise an automatic system of opening and closure of window shades depending on multiple attributes.
[0004] Existing literature describes a camera based device facilitated to automatically close windows upon detection of rain and pollutants in outside air. The device can be operated by voice commands from the user using mobile phones. Another disclosure describes a mechanism for automatic opening and closing of door and window curtains based on severity of pollution and light intensity outside the room. A prior art discusses a pair of externally unfurling electro dynamically operated sunshades. A voice controlled window blind system has also been reported. Another literature describes remotely operable motorized window blinds through user devices. Color reflecting window curtains based on mood sensing have been disclosed in another literature, such that the color changing schedule can be programmed automatically to influence the occupant’s emotional vibes.
[0005] However, none of the disclosures describe a system that can selectively pass light of certain wavelengths through the window. Also, automatic facility of controlling user devices in association with controlling passage of light and air through the window has not been disclosed in any existing literature. Therefore there is need in the art to develop a system of automatic window shade that can be configured to allow passage of one or more predetermined wavelengths of light through the window depending on ambient light, time of the day, emotional and physical activity of the occupant of the room. The proposed automatic window shade is capable to restrict entry of undesired elements of outside air but allow passage of fresh air upon detection of multiple environmental attributes. Color and intensity of indoor lighting can be controlled by the proposed system under manual supervision and automatic control.

[0075] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0076] The terms, descriptions and figures used herein are set forth by way of illustration only. Many variations are possible within the spirit and scope of the subject matter, which is intended to be defined by the following claims and their equivalents in which all terms are meant in their broadest reasonable sense unless otherwise indicated.
[0077] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
