Abstract: Described is a display system comprising a light source, a scanning assembly, and a controller. The light source includes a first plurality of emitters forming a column that emits a first color. The light source also includes a second plurality of emitters forming a column that emits a different color. The scanning assembly includes a reflective surface rotated by the controller using a control signal having a nonlinear, pulsed waveform. The controller drives the first plurality of emitters and the second plurality of emitters in sequence, during respective portions of the nonlinear waveform, and in synchronization with rotation of the reflective surface such that light emitted by the first plurality of emitters and the second plurality of emitters is reflected onto a same pixel of an output image. The controller also adjusts emission durations of individual emitters to compensate for changes in the rotational speed of the reflective surface.

Abstract: Lighting devices and methods utilize multiple independently controllable groups of solid state light emitters of different dominant wavelengths, with operation of the emitter groups being automatically adjusted by processor(s) to provide desired illumination. Operation of the emitter groups may be further affected by sensors and/or user input commands (e.g., sound patterns, gesture patterns, or signal transmission). Operation may be adjusted to compensate for presence, absence, intensity, and/or color point of ambient or incident light. Presence of five or more groups of solid state light emitters provide desirable luminous flux, color point, correlated color temperature (CCT), color rendering index (CRI), CRI R9, and luminous efficacy characteristics of aggregate emissions over a wide range of CCT values, and may permit adjustment of vividness (e.g., relative gamut) and/or melatonin suppression characteristics for a selected color point or CCT.

Abstract: An electrical submersible well pump assembly (ESP) has a spring brake having helical turns mounted between the shaft and one of the housings. The spring brake allows free rotation of the shaft in a driving direction and stops the shaft from rotating in a reverse direction. The spring brake may have one end be affixed to the housing to rotate in unison in both directions. Alternately, the spring brake may have one end affixed to the shaft for rotation with the shaft. Further, the spring brake could be free of being connected to either the shaft or the housing. A shear member may be mounted between the shaft and the housing to prevent any rotation of the shaft during run-in.

Abstract: The present disclosure provides systems and methods that combine physics-based systems with machine learning to generate synthetic LiDAR data that accurately mimics a real-world LiDAR sensor system. In particular, aspects of the present disclosure combine physics-based rendering with machine-learned models such as deep neural networks to simulate both the geometry and intensity of the LiDAR sensor. As one example, a physics-based ray casting approach can be used on a three-dimensional map of an environment to generate an initial three-dimensional point cloud that mimics LiDAR data. According to an aspect of the present disclosure, a machine-learned model can predict one or more dropout probabilities for one or more of the points in the initial three-dimensional point cloud, thereby generating an adjusted three-dimensional point cloud which more realistically simulates real-world LiDAR data.

Abstract: Techniques for reconstructing or building metadata pages in storage nodes that have a delta-log based architecture. The techniques include walking “up” an ancestor chain of a metadata page, detecting the most recent delta update for a metadata entry of the metadata page, writing the most recent delta update to a location of the metadata entry in the metadata page, setting a bitmap entry corresponding to the location of the metadata entry in the metadata page, detecting a less recent delta update for the metadata entry of the metadata page, and, having previously set the bitmap entry corresponding to the location of the metadata entry in the metadata page, avoiding writing the less recent delta update to the location of the metadata entry in the metadata page. In this way, the need to save in memory the entire ancestor chain of the metadata page can be eliminated.

In one example, a catalyst may include a cerium-based support material and a transition metal catalyst loaded on the support material, the transition metal catalyst including nickel and copper, wherein nickel in the transition metal catalyst is included in a monatomic layer loaded on the support material. In some examples, limiting nickel to the monatomic layer may mitigate extensive transition metal catalyst degradation ascribed to sintering of thicker nickel washcoat layers. Further, by utilizing the cerium-based support material, side reactions involving nickel in the transition metal catalyst with other support materials may be prevented.
