Abstract: The techniques described herein relate to methods and systems for three-dimensional (3D) inspection using deep learning model pre-trained with two-dimensional (2D) images. The techniques include transforming a 3D representation (e.g., captured 3D point cloud, 3D profiles, meshes, voxels) to a 2D map, which can be input to a deep learning model pre-trained with 2D images. The 2D map includes elements disposed in an array. Each element includes a vector of a number of geometric features. Such a configuration enables the 2D map to be in a structure acceptable by the 2D deep learning model. The 2D deep learning model generates an output based on the 2D map and provides the output to a subsystem for generating an inspection result. The inspection result can have a 3D result such as a surface area and/or volume.

Abstract: A fuel pressure regulator includes a fuel inlet; a fuel outlet; a seating surface; and a valve member assembly. The valve member assembly includes a poppet and also includes a sealing member which is made of an elastomer material and which is annular in shape and including a sealing member surface. The sealing member is supported by the poppet. The valve member assembly is moveable between 1) a closed position in which the sealing member surface engages the seating surface, thereby preventing fuel flow from the fuel inlet to the fuel outlet and 2) an open position in which the sealing member surface is spaced apart from the seating surface, thereby allowing fuel flow from the fuel inlet to the fuel outlet.

Abstract: A wait duration for a timer action element of a design-time flow plan is set. The wait duration being set relative to a specified data point of a table associated with the design-time flow plan. An operation associated with the timer action element executes at run-time to pause a flow for the wait duration prior to execution of an operation associated with an action element that is set to execute subsequent to the timer action element in the design-time flow plan. A specified timeframe for the timer action element of the design-time flow plan is set. The operation associated with the timer action element to pause the flow for the specified wait duration executes at run-time during the set specified timeframe. A natural language annotation associated with the timer action element of the design-time flow plan is displayed. The annotation presents the set duration and timeframe in a human-readable format.

Abstract: A schematic diagram of an electronic circuit with an unknown function is received. In response to determining that a node equation list associated with the received schematic does not meet a first threshold similarity requirement to a stored node equation list in a database of schematic diagrams of electronic circuits, a main component list associated with the received schematic is created. Each schematic diagram stored in the database of schematic diagrams has a known function, includes an associated node equation list, and includes an associated main component list. In response to determining that the created main component list meets a second threshold requirement for similarity to a stored main component list from the database, a node equation list associated with the stored main component list is retrieved. A function of the received schematic is suggested based on a function of the retrieved node equation list.
