Abstract: A service may provide an e-commerce platform through which users may search for, view, and purchase products. To ensure users receive relevant results when querying for particular products or product classes, a list of ranked classes may be generated, from which the query results are based. For example, products may be classified into classes and particular text from search data may be associated with one or more of the products based on click log data. For instance, input text from previously performed queries may be associated with products interacted with following those queries (e.g., products clicked on to view/purchase). Training data that associates the particular text with the respective one or more classes into which the clicked on products are classified may be generated, and in response to receiving a query including the particular text as input, the list of ranked classes may be generated based on the training data.

Abstract: Utilizing vision systems at a wellsite, which may include operating a video camera to generate a video signal containing images of one or more pieces of equipment or components and receiving the video signal by a processing system, which may then process the images to determine physical and/or operational characteristics associated with the one or more pieces of equipment in the images. The video signal may contain images of a first downhole tubular configured for threadedly coupling with a second downhole tubular and conveyance within a wellbore by an oil and/or gas drilling rig, wherein an outer surface of the first downhole tubular may include a geometric pattern for determining azimuthal orientation of the first downhole tubular. The processing system may then determine the azimuthal orientation of the first downhole tubular based on the images of the geometric pattern.

Abstract: The exit area of a nozzle assembly is varied by translating a ring assembly located at a rear of the engine nacelle. The ring may be axially translatable along the axis of the engine. As the ring translates, the trailing edge of the ring defines a variable nozzle exit area. Translation of the ring creates an upstream exit at a leading edge of the ring assembly. The upstream exit can be used to bleed or otherwise spill flow excess from the engine bypass duct. As the engine operates in various flight conditions, the ring can be translated to obtain lower fan pressure ratios and thereby increase the efficiency of the engine. Fairings partially enclose actuator components for reduced drag.

Abstract: In response to receiving a user inquiry describing one more symptoms of a medical condition, an online medical diagnosis system can determine one or more medical conditions related to the one or more symptoms. The online medical diagnosis system can include a parser to parse the user inquiry into keywords. The keywords can be looked up in a correlation graph model to determine a correlation of the keywords to one or more expert keywords. Keywords meeting a threshold correlation to expert keywords can be used to look up one or more medical conditions using an expert knowledge graph model. A user profile can be used to modify correlation values of keywords to expert keywords. The user profile can also be used to narrow the number medical conditions returned by the expert knowledge graph model. A medical resources crawler can use keywords parsed from stored user inquiries, and expert keywords, to update the correlation graph model.

Abstract: The system and method of the instant invention utilizes a color sensor in order to monitor and control the application of a coating to a substrate when such coating is transferred onto a substrate from a deposition source. Application of the coating to the substrate is terminated when the color sensor detects a pre-programmed end point evidencing the application of an appropriate coating determined by its color.

Abstract: A magnetic worktable includes a worktable body and a plurality of magnetic devices disposed at a worktable body. Positions of the magnetic devices at the worktable body are variable. The magnetic devices are electrically connected to each other via a circuit, such that the magnetic devices can generate a magnetic attraction force when magnetized. The total area of the magnetic devices accounts for a small portion of the worktable body area, allowing a user to change the arrangement and quantity of the magnetic devices by modularization and according to the shape and processing method of a workpiece. Therefore, any workpieces can be fixed to the magnetic devices by magnetic attraction. Accordingly, the magnetic worktable incurs a low manufacturing cost and advantageously features high practicability.

Abstract: A nacelle assembly includes a first portion having an outer fairing and a trailing edge, and a translatable variable area fan nozzle. The fan nozzle includes two or more nozzle segments, each nozzle segment having first and second opposed ends and a leading edge. The nozzle segments are selectively movable between a stowed position and one or more deployed positions. In the deployed position, an upstream bypass flow exit is formed between the trailing edge and the leading edge. The nacelle assembly further includes a guide mechanism for guiding the nozzle segments between the stowed position and the deployed position. A split beavertail failing shields the guide mechanism against air flow when the nozzle segments are in the stowed position.
