The RF control circuitry is configured to apply a balanced AC voltage to the trap electrodes during a first period of time such that an AC voltage applied to a first pair of trap electrodes is of the same magnitude and of opposite sign to an AC voltage applied to a second pair of trap electrodes; apply unbalanced RF voltage to the second pair of trap electrodes during a second period of time; ramp the balanced AC voltage down and the unbalanced RF voltage up during a transition period; and eject ions from the linear ion trap after the second period of time.

Abstract: The present disclosure provides a system and method for real-time visualization of a material during ultrasonic non-destructive testing. The system includes a graphical user interface (GUI) capable of showing a three-dimensional (3-D) image of a composite laminate constructed of a series of two-dimensional (2-D) cross sections.

Abstract: A method of partitioning in video coding for JVET, comprising representing a JVET coding tree unit as a root node in a quadtree plus binary tree (QTBT) structure that can have quadtree or binary partitioning of the root node and quadtree or binary trees branching from each of the leaf nodes. The partitioning at any depth can use asymmetric binary partitioning to split a node represented by a leaf node into two child nodes of unequal size, representing the two child nodes as leaf nodes in a binary tree branching from the parent leaf node and coding the child nodes represented by final leaf nodes of the binary tree with JVET, wherein further partitioning of child nodes split from leaf nodes via asymmetric binary partitioning is allowed recursively along the same branch in any order with symmetric partitioning.

Abstract: The system manages a data structure that defines at least one topic limit for each client computer. The data structure can cause each client computer to display different user interface formats based on a topic limit that is allowed per thread. The data structure causes some devices, which may have a limited viewing area, to only show a single-topic thread, while the data structure also causes other devices to display multi-topic threads. Thus, for high priority topics or for devices having a limited display area, the system can cause the display of a single-topic thread pertaining to a topic to which an incoming message corresponds. This feature can improve user interaction by bringing focus to high priority threads when messages of a particular topic are received at select devices, while allowing other devices to provide a broader perspective of thread formats having multiple topics when the same messages are received.

Abstract: A selective fire firearm may be provided having a fully automatic open bolt and a semi-automatic closed bolt mode of operation.
