A protective covering device is a line of insulated sheathes specially designed to be placed over the wiper blades of a vehicle while it is parked. An elongated, cylindrical tube, each protective covering device is internally fabricated of a durable foam rubber material to ensure optimal insulation potential, with a waterproof, Teflon-coated, or similar water resistant non-stick substance exterior to further prevent corrosion, sticking, and other damage. An alternate embodiment may provide an internal heating element, to keep ice and snow from forming on the elongated sheath, and at least one LED light attached thereon for use in low light level situations.

A glazing comprising a transparent substrate, a plurality of electrically conductive filaments extending over the transparent substrate, wherein the filaments are shaped into a sequence of portions of the perimeters of ellipses, wherein ellipse axial ratios of the ellipses are in the range 1.1 to 4.0 and are selected so that from a pre-defined viewing position and in corresponding pre-defined viewing directions the ellipses in the plane of substrate are viewed as circles. In a preferred embodiment, major axis angles are selected so that from a pre-defined viewing position and in corresponding pre-defined viewing directions the ellipses in the plane of substrate are viewed as circles. In an example of a heated vehicle window, diffraction patterns caused by oncoming headlights interacting with heating filaments of a vehicle window are thereby minimised.

A heated wiper blade for motor vehicles includes an elongated flexible beam and a heating element extending along the beam. The heating element may be configured to provide increased heat at the central portion of the blade and at the opposite ends of the blade. The heating element is comprised of an electrical conductor material that varies the amperage drawn between hot and cold ambient temperature operation. The flexible beam may include curved end portions and a flat or reduced curvature central portion. The heating element is preferably covered and sealed off to prevent loss of heat energy.

Vehicle apparatus includes a glass windshield and a wiper system. A wiper blade has a parking region on the windshield. A deicer selectably provides heat to the parking region. A windshield temperature sensor detects a temperature of the windshield at the parking region. A head-up display is mounted proximate the windshield to display a temperature indicator responsive to the detected temperature. An automatic control circuit is configured to automatically deactivate the deicer when detecting a deiced condition in response to the detected temperature. A manual control element is configured to manually activate and deactivate the deicer. Thus, excessive heating can be avoided based on feedback of the windshield temperature. In addition, the driver is reminded that the deicer is active in a way that simultaneously provides information enabling the driver to independently evaluate the vehicle conditions and to make informed decisions about when to intervene in the automatic operation.

A method of preventing a windshield wiper from freezing to a windshield of a vehicle is provided. The method broadly includes the steps of: (a) monitoring a state of the windshield wiper; (b) initiating a timer when the state of the windshield wiper changes from an off state to an on state; sensing an ambient temperature of the vehicle a first period of time after initiation of the timer if the windshield wiper remains in the on state; and (c) warming a portion of the windshield where the windshield wiper resides in the off state if the sensed ambient temperature of the vehicle is near or below zero degrees Celsius.

A plate for an electro-thermal window includes a heatable transparent conductive film, and bus bars that feed power to the transparent conductive film. The bus bars include a left bus bar connected to a left side edge and a right bus bar connected to a right side edge of the transparent conductive film. The transparent conductive film is divided into regions by a slit continuously or discontinuously formed from the left bus bar to the right bus bar. The regions include first and second regions. A distance between the left bus bar and the right bus bar of the first region is shorter than a distance between the left bus bar and the right bus bar of the second region. A width of the first region in a direction orthogonal to the slit is shorter than a width of the second region in the direction.

An embodiment method of controlling a heating glass includes setting a designated temperature of the heating glass depending on temperature and humidity conditions measured through a sensor, calculating an applied power to reach the designated temperature based on an integrated thermal resistance formed in the heating glass, performing a phase shift of AC power of two or more phases to provide the calculated applied power to a load of the heating glass, and calculating a corrected power in consideration of a resolution of the sensor, wherein respective operations are controlled depending on a set control cycle.
