FIELD OF INVENTION
This invention generally relates to contactless system and method of glass surface cleaning, and, more particularly, to a system and method of contactless cleaning of a windshield of a vehicle.
BACKGROUND
At times, it is required to clean the dust particles from a glass surface, particularly windshields of a vehicle. Typically vehicles are equipped with wipers to clean the windshield and rear view window. The wipers have one or more rubber blades that clean glass surface by to and fro stock. It is advisable to wet the glass surface before operating wipers to avoid damage of the glass surface by rubbing duct particles. However at times, the wipers start operation even before the surface is completely wet and eventually may damage the glass surface. To avoid damage, people prefer to clean the windshield and rear view window manually with a dry cloth or manually soaking complete surface before using wipers.
Accordingly, there is a need for an improved system and method for contactless cleaning of glass exteriors of a vehicle.
SUMMARY OF THE INVENTION
According to embodiments of the invention, a contactless dust cleaning system for a glass surface is disclosed. The system includes a transparent conductive coating on the glass surface, a first conductor, located along at least a first edge of the glass surface and a second conductor, located along at least a second edge of the glass surface. The arrangement being such that the transparent conductive coating, the first conductor and the second conductor are configured to selectively conduct a potential of a specific polarity. The polarity of the

potential in the transparent conductive coating and the first conductor is opposite to the polarity of potential in the second conductor.

The system may include a first conductor 106. The first conductor 106 may be located along at least a first edge of the glass surface. According to an embodiment, the first conductor 106 may be a wire arranged along the edge of glass surface 102. According to another embodiment, the first conductor 106 may be a strip of an electric conductor such as, but not limited to, metal. According to yet another embodiment, the first conductor 106 may extend downwardly on each side edge of the glass surface 102.
The system may include a second conductor 108, located along at least a second edge of the glass surface 102. According to an embodiment, the second conductor 108 may be a wire arranged along the edge of glass surface 102. According to another embodiment, the second conductor 108 may be a strip of an electric conductor such as, but not limited to, metal. According to yet another embodiment, the second edge of the glass surface may be located downward opposite to the first edge of the glass surface 102. According to yet another embodiment, the second conductor 108 may extend upwardly on each side edge of the glass surface 102.
The system may receive electric potential from one or more power source such as, but not limited to, battery. According to an embodiment, the transparent conductive coating/film 104

and the first conductor 106 may receive electric potential from a first power source 110 and the second conductor 108 may receive electric potential from a second power source 112.
According to an embodiment, the arrangement being such that the first conductor 106 and the second conductor 108 are configured to selectively receive an electric potential of a specific polarity such that the polarity of potential in the first conductor 106 may be opposite to the polarity of the voltage in the second conductor 108.
According to another embodiment, the arrangement being such that the transparent conductive coating 104, the first conductor 106 and the second conductor 108 are configured to selectively conduct a potential of a specific polarity. The polarity of the potential in the transparent conductive coating 104 and the first conductor 106 may be opposite to the polarity of potential in the second conductor 108.
According to yet another embodiment, the system may be configured to provide potential either in the first conductor 106 and the second conductor 108 or in the transparent conductive coating 104.
According to yet another embodiment, the system may be configured to provide potential in the first conductor 106, the second conductor 108 and the transparent conductive coating 104 simultaneously.
According to yet another embodiment, the potential may be operated manually. According to yet another embodiment, the potential may be operated automatically. According to one embodiment, the operation of the system may be trigged manually. According to yet another

embodiment, the system may work automatically on a regular interval. According to yet another exemplary embodiment, the system may be operated by a processor.

According to an exemplary illustration, the system may start by providing a specific potential/charge such as, but not limited to, a negative potential to the transparent conductive coating 104. The charge on the conductive coating 104 will help in providing a similar potential on the dust and dirt particles resting on the glass surface 102. After operating the charge in the conductive coating 104 for a pre-defined time, the electric potential may be supplied in the first conductor 106 and the second conductor 108 such that the polarity of electric potential in the first conductor 106 is same as the polarity of the electric potential in the conductive coating 104 and the polarity of electric potential in the second conductor 108 is opposite to the polarity of the electric potential in the conductive coating 104. For the sake of illustration, the polarity in the first conductor 106 may be negative and the polarity of electric potential in the second conductor 108 may be positive. The positive polarity in the second conductor 108 may attract negatively charged dust and dirt particles resting on the glass surface 102, whereas the negative polarity in the first conductor 106 may help in pushing/repelling the negatively charged dust and dirt particles resting on the glass surface 102 towards the second conductor 108.
