Abstract: Methods, systems, and media for presenting annotations across multiple videos are provided. In some implementations, methods for presenting annotations across multiple videos are provided, the methods comprising: receiving a selection of an annotation from a user; identifying, by a hardware processor, a plurality of videos associated with the user account to be associated with the annotation; and presenting the annotation upon rendering one of the plurality of videos.

Abstract: Systems, methods, and computer program products for programming a controller to control a process. A training module is trained to provide predicted responses of the process to control signals using a generic simulator to model the process. Once the training module has been trained, the controller is programmed to control the process by coupling the controller to the training module and using the training module to generate predicted responses of the process to the reception of control signals from the controller. As part of the programming process, one or more parameters of a control program resident on the controller may be adjusted to reduce errors between the responses predicted by the training module and the desired responses intended to be caused by the control signals.

Abstract: A sound making device and system for generating white noise is disclosed. The sound making device generally includes a substantially dome-shaped device that includes an outer acoustic shell and an inner acoustic shell mounted atop a base tray. Both the outer acoustic shell and inner acoustic shell have slots (or openings) that overlap to create apertures through which rushing air can pass. The amount of slot overlap is variable. Further, a variable speed fan is arranged inside the outer acoustic shell and inner acoustic shell for forcing airflow out of the apertures. The sound making device also includes a controller and user interface for adjusting the speed of the fan. Further, a sound making system is provided that includes the sound making device in combination with a mobile app.

Abstract: A spoken command analyzer computing system includes technologies configured to analyze information extracted from a speech sample and, using a joint speaker and phonetic content model, both determine whether the analyzed speech includes certain content (e.g., a command) and to identify the identity of the human speaker of the speech. In response to determining that the identity matches the authorized user's identity and determining that the analyzed speech includes the modeled content (e.g., command), an action corresponding to the verified content (e.g., command) is performed by an associated device.

Abstract: An audio file analyzer computing system includes technologies to, among other things, localize audio events of interest (such as speakers of interest) within an audio file that includes multiple different classes (e.g., different speakers) of audio. The illustrative audio file analyzer computing system uses a seed segment to perform a semi-supervised diarization of the audio file. The seed segment is pre-selected, such as by a human person using an interactive graphical user interface.

Abstract: Methods, systems, and media for presenting annotations across multiple videos are provided. In some implementations, methods for presenting annotations across multiple videos are provided, the methods comprising: presenting a user interface to a user, wherein the user interface prompts the user to select an annotation to be associated with a plurality of videos associated with a user account; receiving a selection of an annotation to associate with the plurality of videos associated with the user account; transmitting data to a server identifying the selected annotation; and causing the server to associate the annotation with the plurality of videos. In some implementations, the methods further comprise: communicating with the server to set placement and timing information of the annotation; and causing the annotation to be presented upon rendering one of the plurality of videos based on the placement information of the annotation and the timing information of the annotation.

Abstract: A compressor blade having an airfoil that comprises oppositely-disposed convex and concave surfaces, oppositely-disposed leading and trailing edges defining therebetween a chord length of the airfoil, a forward-most nose of the airfoil located at the leading edge and having a profile, a blade tip, and an erosion-resistant coating. The coating is present on the concave surface near the trailing edge, optionally present on the nose, optionally present on the convex surface, wherein the convex surface is free of the erosion resistant coating within at least 20% of the chord length from the nose. The thickness of the coating on the concave surface, the convex surface, and the nose is such that, if the gas turbine engine is exposed to an erosive environment, deterioration of the concave surface, the convex surface and the leading edge does not form a pronounced cusp at an intersection of the convex surface and leading edge.

Abstract: A process for depositing coatings, and particularly erosion-resistant coatings suitable for protecting surfaces subjected to collisions with particles, such as a compressor blade of a gas turbine engine. The blade has an airfoil comprising oppositely-disposed convex and concave surfaces, oppositely-disposed leading and trailing edges defining therebetween a chord length of the airfoil, and a blade tip. An erosion-resistant coating is present on at least the concave surface, but not on the convex surface within at least 20% of the chord length from the leading edge.

Abstract: A high emissivity (Hi-E) coating for use on the exhaust baffles of HIRSS systems. HIRSS systems were developed to reduce the infrared (IR) signature of helicopter engines. Increasing operating temperatures of helicopter engines have made the HIRSS systems less effective. An infrared coating applied over selected portions of the HIRSS reduces the IR of the system. The Hi-E coating comprises, in weight percent, 30-80% refractory oxide pigment, 5-20% binder, 1-15% potassium oxide, optionally up to about 15% glass-forming material and the balance refractory oxide powder. When applied to provide a surface finish of 1100Ra microinches or coarser, the coated HIRSS has a significantly reduced hemispherical reflectance in the IR frequency range.

Abstract: An anti-stick coating that inhibits the adhesion of contaminants that form deposits on the internal cooling passages of gas turbine engine components. The anti-stick coating is formed as an outer coating of the internal cooling passages, and preferably overlies an environmental coating such as a diffusion aluminide coating formed on the passage surfaces. The outer coating has a thickness of not greater than three micrometers, and is resistant to adhesion by dirt contaminants as a result of comprising at least one layer of tantala, titania, hafnia, niobium oxide, yttria, silica and/or alumina. The outer coating is preferably deposited directly on the environmental coating by chemical vapor deposition.
