Abstract: A system and method for automatically providing artifact warnings in Pulsed-Wave (PW) Doppler imaging is provided. The method includes acquiring, by an ultrasound system at a pulse repetition frequency (PRF), Pulsed-Wave (PW) Doppler signals from a selected gate position in a high PRF mode. The method includes determining, by a processor of the ultrasound system based on the PRF, a position of a virtual gate along a PW line in a B-mode image. The method includes presenting, at a display, the virtual gate at the determined position along the PW line in the B-mode image. The method includes analyzing, by the processor, B-mode image intensity values at the virtual gate in the B-mode image to determine whether the B-mode image intensity values exceed an intensity threshold. The method includes providing, by the at least one processor, a virtual gate warning when the B-mode image intensity values exceed the intensity threshold.

Abstract: In a presentation document, changes to an element in a first slide of the presentation may be propagated throughout the presentation. A first slide may be displayed, in a user interface, with a first option to edit an element of the first slide. A selection of the first option may cause an edit to the first element. A second option may be displayed if the first element has a dependent relationship with a master element of the presentation. Upon selection of the second option, the master element may be updated based on the edit to the element of the first slide. The edit may be propagated to other elements of the presentation that have the dependent relationship with the master element.

Abstract: Natural language image search is described, for example, whereby natural language queries may be used to retrieve images from a store of images automatically tagged with image tags being concepts of an ontology (which may comprise a hierarchy of concepts). In various examples, a natural language query is mapped to one or more of a plurality of image tags, and the mapped query is used for retrieval. In various examples, the query is mapped by computing one or more distance measures between the query and the image tags, the distance measures being computed with respect to the ontology and/or with respect to a semantic space of words computed from a natural language corpus. In examples, the image tags may be associated with bounding boxes of objects depicted in the images, and a user may navigate the store of images by selecting a bounding box and/or an image.

Abstract: A method includes driving a first transistor to conduct a first current into an inductor when conductive and driving a second transistor to conduct a second current into the inductor when conductive. A first sense current is generated in response to the first current and a copy of the second current. A second sense current is generated in response to the second current and a copy of the first current. The first sense current is adjusted in response to the copy of the second current when the first transistor is nonconductive. The second sense current is adjusted in response to the copy of the first current when the second transistor is nonconductive. On times of the first and second transistors are controlled in response to a sum of the first and second sense currents.

Abstract: Described is a system for creating an intelligent testing queue for improved quality assurance (QA) testing of services (or microservices). The system may perform a graphical analysis of interactions between services to derive testing constraints. For example, the system may monitor services to identify interactions (e.g. API accesses) between the services, and store the interactions as a directed graph representation. The system may traverse the directed graph (e.g. via a breadth-first search) to determine service dependencies. Based on the probability of failure for the testing operations and the service dependencies, the system create a specialized testing queue. By performing testing operations according to the specialized queue, the system may improve certain metrics associated with QA processes such as mean time to failure (MTTF) and mean time to diagnose (MTTD).
