Abstract: Hyper-hemispherical images may be combined to generate a rectangular projection of a spherical image having an equatorial stitch line along of a line of lowest distortion in the two images. First and second circular images are received representing respective hyper-hemispherical fields of view. A video processing device may project each circular image to a respective rectangular image by mapping an outer edge of the circular image to a first edge of the rectangular image and mapping a center point of the circular image to a second edge of the first rectangular image. The rectangular images may be stitched together along the edges corresponding to the outer edge of the original circular image.

Abstract: A turbomachine airfoil element includes an airfoil having pressure and suction sides spaced apart from one another in a thickness direction and joined to one another at leading and trailing edges. The airfoil extends in a radial direction a span that is in a range of 0.60-0.70 inch (15.3-17.8 mm). A chord length extends in a chordwise direction from the leading edge to the trailing edge at 50% span and is in a range of 0.90-1.00 inch (22.9-25.5 mm). The airfoil element includes at least two of a first mode with a frequency of 5327±10% Hz, a second mode with a frequency of 8393±10% Hz, a third mode with a frequency of 16289±10% Hz, a fourth mode with a frequency of 25049±10% Hz and a fifth mode with a frequency of 27423±10% Hz.

Abstract: An airfoil has pressure and suction sides spaced apart from one another in a thickness direction and joined to one another at leading and trailing edges. The airfoil extends in a radial direction a span that is in a range of 0.70-0.83 inch (17.8-21.1 mm). A chord length extends in a chordwise direction from the leading edge to the trailing edge at 50% span is in a range of 0.34-0.45 inch (8.5-11.5 mm). The airfoil element includes at least three of a first mode with a frequency of 3748±15% Hz, a second mode with a frequency of 6416±15% Hz, a third mode with a frequency of 14418±15% Hz, a fourth mode with a frequency of 17417±15% Hz, a fifth mode with a frequency of 19326±15% Hz and a sixth mode with a frequency of 26648±15% Hz.

Abstract: The present invention relates generally to a method and apparatus for deploying and/or retrieving an object (e.g., a vena cava filter) in a cavity (e.g., a vena cava) using a system configured to: (i) maintain grip of the unsheathed object in the cavity until deliberately released, (ii) prevent premature release of the object in the cavity, and/or (iii) facilitate retrieval by first everting said object, then withdrawing the object through a guiding catheter (e.g., retrieval via eversion).

Abstract: The present disclosure is directed toward systems and methods for identifying and abating padding oracle attacks. One or more embodiments described herein identify and abate padding oracle attacks without necessitating any changes or upgrades to an existing encryption system by providing an intermediate service that can intercept communications from a client-computing device intended for a padding oracle.

Abstract: The present disclosure includes airfoils for use in gas turbine engines. The airfoils comprise a fillet having a height of greater than 20% of the airfoil body span length. The airfoil may be a blade or a vane. Further, such airfoils may be used in the high pressure compressor section, as well as other gas turbine engine sections.

Abstract: A printer apparatus and a method for continuously printing a three-dimensional (3D) object. The printer apparatus has an elongated container for containing build fluid comprising a monomer from which the 3D object is made. A means for continuous conveying a build platform has a build surface that descending down into the build fluid. A matrix of light emitting elements are disposed above the elongated container, and emit a predetermined pattern of a reactive light toward the continuously conveyed build surface and at the upper surface of the build fluid. The reactive light has a predetermined pattern that polymerizes and/or agglomerates a portion of the upper surface of the build fluid into a build material having a build pattern comprising the build material. The build platform can have a plurality of build surface segments attached in series along a continuous conveyor.
