Abstract:

In some embodiments, high-energy additive manufacturing (HE-AM) (e.g., directed energy deposition, powder injection, powder bed fusion, electron beam melting, solid-state, and ultrasonic) is used to overcome constraints of comparative EES fabrication techniques to produce chemical additive-free electrodes with complex, highly versatile designs for next generation EES. An exemplary rapid fabrication technique provides an approach for improving electrochemical performance while increasing efficiency and sustainability, reducing time to market, and lowering production costs. With this exemplary technique, which utilizes computer models for location specific layer-by-layer fabrication of three-dimensional parts (e.g., versatile design), a high degree of control over processing conditions may be achieved to enhance both the design and performance of EES systems.

Abstract:

A method of interpreting a digit-to-digit gesture based on roll values for a wrist-wearable device is disclosed. The method includes, receiving an indication at a first point in time that a user donning the wrist-wearable device is providing a digit-to-digit gesture in which one of the user's digits touches another of the user's digits without contacting the display of the wearable device. The method further includes, in accordance with a determination that the digit-to-digit gesture is provided while data indicates that the wrist-wearable device has a first roll value, causing a target device in communication with the wearable device to perform a first input command and receiving another indication at a second point in time that is after the first point in time that the user is providing the digit-to-digit gesture again, causing the target device to perform a second input command that is distinct from the first input command.

Abstract:

The disclosed computer-implemented method may include (1) receiving a video with scenes, (2) creating an encoded video having an overall bitrate by (a) determining, for each of the scenes, a rate-distortion model, (b) determining, for each of the scenes, a downsampling-distortion model, (c) using the rate-distortion models of the scenes to determine, for each of the scenes, a per-scene bitrate that satisfies the overall bitrate, (d) determining, for each of the scenes, a per-scene resolution for the scene based on the rate-distortion model of the scene and the downsampling-distortion model of the scene, and (e) creating, for each of the scenes, an encoded scene having the per-scene bitrate of the scene and the per-scene resolution of the scene, and (3) streaming the encoded video at the overall bitrate by streaming the encoded scene of one of the scenes. Various other methods, systems, and computer-readable media are also disclosed.

Abstract:

In some embodiments, an encoder device is disclosed to generate single-channel standard dynamic range/high dynamic range content predictors. The device receives a standard dynamic range image content and a representation of a high dynamic range image content. The device determines a first mapping function to map the standard dynamic range image content to the high dynamic range image content. The device generates a single channel prediction metadata based on the first mapping function, such that a decoder device can subsequently render a predicted high dynamic range image content by applying the metadata to transform the standard dynamic range image content to the predicted high definition image content.

Abstract:

A software analytic is associated with a software application that is being executed by a tenant. In aspects, the analytic is initiated and triggered from one of a plurality of software containers at an edge node. Each of the software containers at the edge node is provisioned and preconfigured with a resource usage for a single tenant. One of the plurality of software containers at the edge node is selected for use by the software analytic. Subsequently, tenant-specific data is obtained for the analytic utilizing the selected container. The tenant-specific data does not include data from any other tenant. The tenant-specific data and the analytic are then sent from the edge node to a cluster of nodes for execution at the cluster of nodes.
