  • Patent number: 6906287
    Abstract: Opposing substrates of a vehicle window are laminated to one another using a polymer inclusive interlayer which has a notch or cut-out portion defined therein. Following lamination, at least one bus bar(s) supported by one of the substrates is exposed in this notch or cut-out portion of the interlayer. Then, an external connector may be electrically connected to the bus bar(s) at a location between the opposed substrates, by sliding a portion of the connector into a gap between the two laminated substrates at a location where the bus bar(s) is exposed due to the notch or cut-out in the interlayer. Because the connector can be electrically connected to the bus bar(s) after the lamination process, various techniques (e.g., nipper rolls, vacuum apparatus, etc.) may be used to laminate the substrates to one another prior to this electrical connection.

  • Patent number: 6870134
    Abstract: A heatable window (e.g., vehicle windshield) includes a heatable layer including one or more conductive layers. The heatable layer may be a single layer conductive coating, or alternatively may be a multi-layer heatable coating including one or more dielectric layer(s) in addition to one or more heatable conductive layer(s). Bus bars are provided so that a voltage may be applied across at least one conductive layer of the coating, in order to heat the layer so that the coating generates heat for defogging, deicing and/or desnowing the window. At least a portion of one of the bus bars includes both an underlying conductive base layer portion, and an overlying conductive braid portion that is conductively attached to the conductive base portion. The braid portion significantly increases the current capacity of the bus bar portion if so desired.

  • Patent number: 6734396
    Abstract: A heatable vehicle window includes a bottom bus bar and a plurality of top bus bars. Voltages or electric potentials applied to the top bus bars are different, so that a first one of the top bus bars is at a given electric potential and another one of the top bus bars is at another electric potential (i.e., the voltages/potentials are offset from one another). The degree to which the top bus bar voltages/potentials are offset relative to one another is a function of the distance each respective bus bar is from the bottom bus bar across the heatable layer(s). Given a substantially continuous heatable layer(s), this can in certain example embodiments enable approximately uniform heating of the window (e.g., laminated vehicle windshield, laminated vehicle backlite, or laminated vehicle sidelite).

  • Patent number: 6625875
    Abstract: A heatable vehicle window (e.g., windshield, sidelite or backlite) includes a multi-layer coating formed on a substrate. The multi-layer coating includes at least one dielectric layer and at least one conductive layer. A pair of bus bars are deposited on the substrate over the coating, so that at least the dielectric layer is provided between the bus bars and the conductive layer(s). In order to create an electrical connection between the bus bars and the conductive layer(s) of the coating, the bus bars and/or coating is/are heated to a temperature sufficient to permit the bus bars to reach molten or semi-molten form. Portions of bus bar material then flow down through at least the dielectric layer of the coating (i.e., forming a contact hole in the coating) so as to contact the coating's conductive layer(s). After cooling of the newly formed bus bars, the window may be selectively heated by passing current through the conductive layer(s) via the bus bars.

  • Patent number: 6607622
    Abstract: A method for adhering/bonding a frame profile (e.g., weather strip, water seal, spacer, etc.) to a substrate (e.g., glass or plastic substrate) in the context of a vehicle window unit. A frame profile is formed via extrusion so as to include both a polymer profile portion and a selectively activatable interface or adhesive portion. Following extrusion, the frame profile may be stored, cut, trimmed, cure, etc. At some point following extrusion, the interface/adhesive is in a non-activated state, or at least in a state where it is not activated to an extent sufficient to bond/adhere the frame to the substrate. To adhere/bond the frame profile to the substrate, the interface/adhesive portion of the frame profile is activated (e.g., heat activated). Following and/or during heat activation, the frame profile is pressed against the substrate, or vice versa, so that the activated adhesive bonds the polymer profile to the substrate.

  • Patent number: 6559419
    Abstract: A heatable vehicle window including at least three different heating zones. A conductive coating is divided into at least three different heatable coating portions which are spaced apart from one another. A top bus bar includes a step or protruding portion which extends toward the bottom bus bar at an area of an intermediate one of the heatable coating portions. This protruding portion enables, for example and without limitation, a rain sensor or toll device to efficiently transmit and/or receive signals (e.g. IR signals, RF signals, or the like) through the window at an area behind the protrusion where the coating has been deleted. Because of the division of the coating into at least three different heatable coating portions, approximately uniform current distribution is enabled along the top bus bar (even at the protruding portion thereof) so as to reduce the likelihood of overheating.

  • Patent number: 6336999
    Abstract: A sputter coating apparatus includes at least a first sputter coating line and a second sputter coating line. The first and second sputter coating lines may be operated in parallel with one another in certain embodiments in order to independently form coating systems and respective coated articles. However, the two coating lines may also be utilized so as to operate in series with one another to form a coated article. In the latter case, a transition zone is provided between an end of the first line and an end of the second line so as to selectively couple an output of the first line to an input of the second line when it is desired to utilize the two sputter coating lines in series with one another. In such a manner, it is possible to avoid many of the inefficiencies associated with conventional sputter coating apparatuses and processes.
