Abstract: In described examples, a system (e.g., a security system or a vehicle operator assistance system) is configured to configure a phased spatial light modulator (SLM) to generate a diffraction pattern. A coherent light source is optically coupled to direct coherent light upon the SLM. The SLM is configured to project diffracted coherent light toward a region of interest. An optical element is configured to focus the diffracted coherent light toward the at least one region of interest.

Abstract: A method to compress an image includes assigning each pixel of the image to a cluster based on a red-green-blue (RGB) location of the pixel. The method also includes updating a centroid of the cluster after each pixel is assigned, based at least in part on the RGB location of the pixel, where the centroid is an RGB location. The method includes replacing each pixel in the image with an RGB value of the centroid of the cluster to which the pixel is assigned. The method also includes instructing a display to display a compressed image where, in the compressed image, each pixel in the image is replaced with the RGB value of the centroid of the cluster to which the pixel is assigned.

Abstract: A method includes receiving, by a frame converter, a frame of pixel data and converting, by the frame converter, the frame to a first frame division unit. The method also includes receiving, by a translation circuit, a pixel coordinate and cropping and shifting, by the translation circuit, the first frame division unit based on the pixel coordinate, to produce a second frame division unit. Additionally, the method includes outputting, by the translation circuit, the second frame division unit.

Abstract: A method includes rendering, by at least one processor, a first sub-frame of an image, where the first sub-frame includes a first subset of pixels of the image. The method includes displaying the first sub-frame on a display. The method also includes rendering, by the at least one processor, a second sub-frame of the image, where the second sub-frame includes a second subset of pixels of the image, and where the second sub-frame is shifted a half-pixel diagonally from the first sub-frame. The method also includes displaying the second sub-frame on the display after displaying the first sub-frame, where the display is optically shifted a half-pixel diagonally to display the second sub-frame.

Abstract: The buttstock assembly uses a modular design including interchangeable end attachments and sling strap connectors. The interchangeable end attachments allow the buttstock to have different toe heights and configurations for different shooting applications. The interchangeable strap connectors allow the use of either quick-disconnect style sling swivels or more traditional fixed strap loops as desired. The buttstock assembly also uses a “trigger” style locking mechanism to selectively position and lock the buttstock along the length of the extension tube to adjust the overall length of pull of the weapon.

Abstract: The disclosure provides compositions, systems, and related method for using nanopore-based detection of nucleic acid displacement circuits. In some embodiments, output strands contain orthogonal barcode sequences that are captured by nanopore systems to produce a unique and recognizable current signal. Machine learning models can be used to differentiate a plurality of current signals and, therefore, monitor detection and quantification of multiple nucleic acid displacement circuits in a single pot reaction.
