Abstract: A method for image enhancement includes capturing multiple input images of a scene, including at least a first input image having a first field of view (FOV) captured with a first focal depth and a second input image having a second FOV captured with a second focal depth. The input images in the sequence are preprocessed so as to align the images. The aligned images are processed in a neural network, which generates an output image having an extended depth of field encompassing at least the first and second focal depths.

Abstract: Among other things, this document describes systems, devices, and methods for improving cache performance when caching multiple versions of an object. In some embodiments, a network cache can execute a cache eviction algorithm that considers the versatility of object versions when making eviction decisions. The techniques described herein can be applied to wide variety of media objects, such as an original image and a set of derivative images in various formats, sizes, or compression levels. A versatile version is versatile because it can be substituted for one or more other versions requested by a client. Hence, the techniques described herein may prefer, under certain conditions, to evict from a network cache less versatile versions prior to evicting more versatile versions.

Abstract: A protective wear sleeve for a cutting tool assembly that includes a solid body that has a shaft portion, a radial collar portion, and a central bore that defines a central axis. The shaft has a forward end and a rearward end, wherein the radial collar is integral with the forward end. The radial collar has a ring support surface that faces at least partially in an outward radial direction. The forward end of the shaft and the radial collar together define a tooth support surface that faces in a forward direction and has an outer diameter. At least one wear ring is disposed on the ring support surface and extends around the radial collar. The at least one wear ring has a hardness greater than that of the radial collar and has an outer diameter greater than that of the outer diameter of the tooth support surface.

Abstract: A method makes use of a minimally-shearing feeder mechanism supplying a desired flow of particulate solids mixture, with minimal to no sifting segregation to a desired location. The feeder methodology maintains a uniform concentration of each size of particle within the mixture.

Abstract: A bed of particulate solids is fluidized in a test chamber to yield multiple test samples for subsequent evaluation of segregation effects. A controlled stream of gas enters the chamber in a series of flow rate cycles each progressively increasing to a maximum rate of gas flow and then decreasing, the maximum rate increasing for successive cycles. An indicating function is formed from measurements of corresponding rates of gas flow and pressure across the bed. Upon termination of the fluidization, multiple samples are sequentially extracted from a single space at the bottom of the test chamber.

Abstract: A method and apparatus enables testing of sifting segregation of a particulate solid mixture in a storage bin or hopper. The apparatus makes use of a convergently and divergently angled hopper for collecting the mixture. The apparatus further makes use of a minimally-shearing feeder mechanism supplying a desired flow of mixture, with minimal to no sifting segregation, to the angled hopper. A collection mechanism removes samples of the mixture from the angled hopper for analysis with minimal disruption of the particles of the mixture relative to each other. Thus, samples resulting from the testing apparatus, and corresponding method, are highly representative of mixture conditions within a larger storage hopper.
