Abstract: A method is provided for assembling an apparatus. During this method, a circuit element is arranged with a circuit board. The circuit element includes an element aperture. The circuit board includes a board aperture. A plunger is moved in a first direction to pass a distal end of the plunger through the element aperture and the board aperture and into a volume adjacent the circuit board. A retainer is pivoted within the volume. The retainer is pivotally mounted to the plunger at the distal end of the plunger. The plunger is moved in a second direction to clamp the circuit board between the retainer and the circuit element.

Abstract: Aspects of the present disclosure provide technologies for storing, transporting, and disposing of medical waste (e.g., sharps and biohazardous materials). Medical waste commonly results after medical treatment of patients. For example, a piece of medical equipment may be stored after use in a channel of a structural element and then restrained within the channel using a restrictive element. The entire assembly may be surrounded by an internal cavity formed by a first portion of a housing abutting a second portion of a housing, thereby creating a leak-resistant seal. The technologies described herein may be portable so that first responders and medical practitioners may carry them to any emergency location. In situations, the housing surrounding the assembly can be incinerated, thereby destroying any pathogenic contamination.

Abstract: Disclosed herein include antibodies or fragments thereof having specificity to a sarbecovirus spike protein. Also provided are compositions, methods, and kits for using said antibodies or fragments thereof for preventing or treating, for example a coronavirus infection.

Abstract: A computer-readable storage medium may include executable instructions stored thereon that, when executed by a processor, may be configured to establish a connection to a node of a distributed ledger network that maintains a distributed ledger. The processor may obtain a first dataset from a first user, perform pre-processing on the first dataset to obtain a first data asset based on the first dataset, and store the first data asset. The processor may calculate a first value for the first data asset and generate a first data proposition based on the first data asset. The processor may obtain acceptance data from a second user, which may include data indicating acceptance by the second user of the first data proposition. The processor may transmit a first distributed ledger record to the node of the distributed ledger network.

The system includes at least one internal battery located in the prosthetic arm, at least one external battery connected to the prosthetic arm, and a master controller configured to connect either the at least one internal battery or the at least one external battery to a power bus to power the prosthetic arm.

Abstract: Described are methods and compositions for clinical proven safe and effective treatment of ulcerative colitis, particularly moderately to severely active ulcerative colitis in patients who have had an inadequate response to or are intolerant of a conventional or existing therapy by intravenous and/or subcutaneous administration of an anti-IL-12/IL-23p40 antibody.

Abstract: A failure recommendation system for a command line interface (CLI) uses machine learning to predict the most likely command to correct an unsuccessful or failed attempt to perform an intended operation using the CLI. The failure recommendation system is based on a conditional probability model trained on failure-success pairs of commands from CLI telemetry data to learn the most likely command to remediate a failure. The conditional probability model predicts the most likely command based on a failure type and the failed command. The failure type is identified through a failure type classifier and is used to select the most likely command to remediate a failure from the different events that may lead to a failure.

Abstract: This invention concerns a method of filming a subject to be projected as a Pepper's Ghost image. The method may comprise filming a subject under a lighting arrangement having one or more front lights for illuminating a front of a subject and one or more backlights. The lights may be controlled such that the total brightness of the one or more front lights, as measured of the subject, is less than or approximately the same as the total brightness of the one or more backlights, as measured at the subject. The subject may be located directly above one or more floor lights such the subject is illuminated from below by the one or more floor lights.

Abstract: Virtual and augmented reality sports training environments are disclosed. A user interacts with virtual players in a simulated environment of a virtual reality sporting event. In some embodiments, the user's actions and decisions are monitored by the simulated environment. The environment evaluates the user's performance, and provides performance feedback based on the user's decisions and timing. In one application, real life pitchers and their pitching data are tracked and replicated in a simulated pitching environment. A team of users may practice against a simulation of a pitcher they are about to compete against, swinging at pitches that they would see in a real game. Such environments may maximize effective practice time for users, and help develop better players with improved decision-making skills. Some embodiments include various pitch recognition training, which may be against replicated real-life pitchers.

Abstract: To simplify assisting a user in their day-to-day activities, a communication for performing an action may be sent to a user in the form of a query, where the query includes the most likely set of choices for the action arranged in a group of dichotomous (e.g., yes/no) or multiple choice answers. In this manner, a user may respond to the query by simply selecting one of the dichotomous or multiple choice answers. Historical logs of past actions, responses, queries, and so forth, may be used to predict future user actions or needs, and to formulate future queries for sending to the user. These techniques may be implemented, for example, through a remote coordination server or directly through a user's personal electronics device.

Abstract: Estimating the ego-motion of a vehicle, e.g., the self-motion of the vehicle, can be improved by pre-processing data from two or more radars onboard the vehicle using a processor common to the two or more radars. The common processor can pre-process the data using a velocity vector processing technique that can estimate a velocity vector at each point of a predefined number of points, such as arranged in a grid in the field-of-view of radars, with coordinates (X, Y, Z (optional)), where U is the component of the velocity in the X-direction, V is the component of the velocity in the Y-direction, and W is the component of the velocity in the optional Z-direction.
