  • Patent number: 9818888
    Abstract: A method of forming a coating layer on a glass substrate in a glass manufacturing process includes: providing a first coating precursor material for a selected coating layer composition to at least one multislot coater to form a first coating region of the selected coating layer; and providing a second coating precursor material for the selected coating layer composition to the multislot coater to form a second coating region of the selected coating layer over the first region. The first coating precursor material is different than the second precursor coating material.

  • Patent number: 7204130
    Abstract: A moisture detector can include a first elongated conductor disposed on a substrate. The first conductor can define a zigzag path between the opposite ends thereof. A second conductor can also be disposed on the substrate at least partially surrounding the first conductor. The second conductor can define between opposite ends thereof a zigzag path having a portion thereof that is positioned in substantially spaced parallel relation with the zigzag path of the first conductor along the sides thereof. A power conductor disposed on the substrate can be electrically connected to the first conductor intermediate the ends thereof via a gap defined between the ends of the second conductor. Ground conductors disposed on the substrate can be electrically connected to the ends of the second conductor. A temperature sensor can be utilized to correct the response of the moisture detector for temperature.
