Abstract: A system and method for monitoring a dry gas seal positionable between a stationary housing and a rotatable shaft. A plurality of sense elements may rotate in response to the rotation of the rotatable shaft and a speed sensor may sense the speed of the rotatable shaft at speeds below one thousand rotations per minute based on sensing the plurality of sense elements. An acoustic emissions sensor may sense when a first seal face and a second seal face forming a seal interface of the dry gas seal are in an operational condition relative to one another. A processor may receive output signals from the speed sensor and the acoustic emissions sensor, and may establish an operating condition of the dry gas seal based on the signal from the speed sensor when the first seal face and the second seal face reach the operational condition relative to one another.

Abstract: For a scene comprising real-world objects and generated (CG) objects, the scene characterized by a scene geometry of a first time, one or more processors can generate, based on the scene geometry, shadow information for each of one or more shadows cast by a CG object of the scene on one or more real-world objects of the scene. The one or more processors can rendering and display a frame of the scene as a function of the shadow information and a scene geometry at a time of the rendering later than the first time. In some examples, the shadow information includes shadow factors and identifiers. Each shadow factor can describe a light attenuation effect of a cast shadow on a real world object surface and can be incorporated into a shading atlas of the scene. Each identifier identifies a real-world object surface of the scene affected by a shadow factor.

Further, aspects of the present disclosure may determine whether at least a portion of the first content group occludes or potentially occludes at least a portion of the second content group. Additionally, the present disclosure may represent the first content group and the second content group based on the determination whether at least a portion of the first content group occludes or potentially occludes at least a portion of the second content group. In some aspects, the first content group may include at least some real content and the second content group includes at least some augmented content. The present disclosure may also render at least a portion of surfaces of the first content group using an occlusion material.

Abstract: Methods, systems, and devices for computer graphics are described. A device may perform a shadow rendering operation in an object-space shading pipeline for a set of potentially visible surfaces. The device may represent the potentially visible surfaces in an atlas. The device may determine a set of world-space coordinates corresponding to the one or more potentially visible surfaces and may store the set of world-space coordinates in a geometry buffer (G-buffer). The device may determine a number of shadow factors associated with the potentially visible surfaces based on a transformation of the world-space coordinates stored in the G-buffer and a set of depth values associated with each shadow caster present in a scene. The device may store the shadow factors in an atlas shadow mask and perform a shading of the potentially visible surfaces in the atlas based on the atlas shadow mask.

Abstract: Apparatuses and methods are disclosed for comparing a first biosequence string with a second biosequence string to assess similarity between those biosequence strings. For example, a field programmable gate array (FPGA) can be used to (1) detect substrings of the second biosequence string that are matches to substrings of the first biosequence string, and (2) map the detected substrings of the second biosequence string to corresponding positions in the first biosequence string where the detected substrings are located based on a data structure that links substrings of the first biosequence string to positions in the first biosequence string where the substrings of the first biosequence string are located. These operations can be used to seed an alignment between the first and second biosequence strings that permits comparisons to be performed over longer substrings of the first and second biosequence strings so that similarities between those longer substrings can be quantified.

Abstract: A build assembly and a method of manufacturing the same are provided. The build assembly includes a first component, a second component, and a support structure coupling the two components together to fix their relative position.

The support structure may also be connected to the components and may define channels for removing additive powder from within or around the components.

Abstract: A triangulation sensing system includes a projection axis configuration and an imaging axis configuration. The projection axis configuration includes a triangulation light source (e.g. an incoherent source) and a variable focus lens (VFL) that is controlled to rapidly periodically modulate a triangulation light focus position (TLFP) along a Z axis over a focus position scan range, to provide a corresponding triangulation light extended focus range (TLEFR) that supports accurate measurement throughout. In some implementations, the triangulation system may be configured to provide the best measurement accuracy for a workpiece region of interest (WROI) by exposing its triangulation image only when the scanned TLFP temporarily coincides with the WROI Z height. In some implementations, the triangulation system may be configured to limit various measurement operations to using only an operational pixel subset of a detector that receives image light from the WROI, in order to shorten the measurement time.
