  • Publication number: 20040107641
    Abstract: A region in a metallic panel that facilitates the transmission of radio frequency signals. The metallic panel may be included in a window such as the window of a vehicle or building. For example, the metallic panel may be used for heating or to reflect infrared radiation. An aperture is formed in the metallic panel to enable radio frequency signals to be transmitted through the metallic panel. The design of the aperture may be selected to enable the transmission of the desired frequency band. Furthermore, the aperture is designed such that there is a taper in the transmission amplitude and/or the phase to suppress lobing effects on the other side of the aperture. In an embodiment in which the metallic panel is used to conduct electric current, the aperture may be oriented such that the current may flow between the openings of the aperture. Accordingly, there may be uniform heating across the metallic panel without blocking the transmission of radio frequency signals in the desired frequency band.

  • Patent number: 5916625
    Abstract: The detrimental effects of fluctuating humidity are neutralized by adjusting the viscosity of a waterborne coating as it is being conducted to the spraying device. A predetermined amount of water or other viscosity modifying additive is mixed continuously with the coating in the coating supply line immediately upstream from the spray device. The amount of water or other additive to be added may be determined by monitoring the humidity in the spray zone. Preferably, an automated feedback control system is employed to adjust the amount of water or other viscosity altering additive being mixed into the coating stream.
