Abstract: Systems and methods for providing a door seal system for top-hanging sliding doors. In some implementations, two angled mating surfaces are used, one angled surface on a fixed frame and one reversed angled surface on the slideable door panel. The slideable door panel slides directly parallel to the fixed door frame. A mating seal surface is created that is only in frictional contact for a small portion of the linear slide distance of the door panel. In some implementations, rather than placing two opposing angled seal surfaces, the sealing system has one angled surface on the fixed door frame. In such implementations, the sliding door panel is adjusted to be in a reverse angled orientation relative to the angled surface of the fixed door frame. Seal designs for the rear vertical edge of the slideable door panel are also provided herein.

Abstract: Systems and methods for providing a drop seal assembly which is concealed within an opening in the bottom of a sliding door panel of a top-hanging sliding door. The drop seal assembly may include bottom guide which defines a downward facing elongated slot or track which receives a sill guide therein. The drop seal assembly also includes a drop down acoustic seal which automatically drops down to contact the floor surface below the door panel when the door panel is moved from an open position into a closed position. The distance that the seal drops down upon closing of the door panel may be selectively adjustable to accommodate variances in the air gap between the door bottom and the floor surface due to particular installation conditions. A concealed magnetic bottom seal activator may be used to provide self-adjusting activation of the door bottom seal assembly using two opposing magnets.

Abstract: A sliding door system may satisfy the requirements of, and be fire-rated in accordance with, UL10B (“Standard for Fire Tests of Door Assemblies”), and/or satisfy the requirements of, and be pressure-rated in accordance with, UL10C (“Standard for Positive Pressure Fire Tests of Door Assemblies”).

Abstract: Systems and methods for obtaining and playing video advertisements in conjunction with play of video content use information about the viewability of an instantiation of a video player software application. An instantiation of the video player software application generates a viewability score which is intended to reflect a degree of confidence that the instantiation of the video player software application is located on a part of a webpage that currently appears on a user's display screen. Information used to generate the viewability score can be gathered during play of a video. The information used to generate a viewability score can include information about user performed actions and information that indicates the degree to which the user is engaged by a video.

Abstract: Systems and methods for generating a content score for a video that is indicative of how engaging the video is to viewers makes use of a modified completion rate factor. The modified completion rate factor indicates the percentage of viewers that played the video and that watched at least a predetermined number of second of the video. Other viewing factors may also be used to help generate the content score of the video.

Abstract: Systems and methods for obtaining and playing video advertisements in conjunction with play of video content make use of partner advertising providers to reduce the time required to identify and obtain the video advertisements. An instantiation of a video player software application receives and analyzes bids from partner advertising providers and selects a winning bid before a user issues a play command. As a result, it is often possible to immediately begin playing a video advertisement the instant the user issues a play command.
