The shaft assembly extends distally from the body and includes an acoustic waveguide. The end effector includes an ultrasonic blade that is in acoustic communication with the acoustic waveguide. The activation member is operable to move in a second direction to activate the end effector in a mode of operation selected by movement of the activation member in the first direction.

Abstract: A vertical gallium nitride (GaN) PN diode uses epitaxial growth of a thick drift region with a very low carrier concentration and a carefully designed multi-zone junction termination extension to achieve high voltage blocking and high-power efficiency. An exemplary large area (1 mm2) diode had a forward pulsed current of 3.5 A, an 8.3 m?-cm2 specific on-resistance, and a 5.3 kV reverse breakdown. A smaller area diode (0.063 mm2) was capable of 6.4 kV breakdown with a specific on-resistance of 10.2 m?-cm2, when accounting for current spreading through the drift region at a 45° angle.

Abstract: A system and method for human motion detection and tracking are disclosed. In one embodiment, a smart device having an optical sensing instrument monitors a stage having a mat. Memory is accessible to a processor and communicatively coupled to the optical sensing instrument.

The image frame is then converted into a designated image frame format, which is provided to a pose estimator. A two-dimensional dataset is received from the pose estimator. The system then converts, using inverse kinematics, the two-dimensional dataset into a three-dimensional dataset, which includes time-independent static joint positions, and then calculates, using the three-dimensional dataset in conjunction with the data frame, the position of each of the respective plurality of body parts in the image frame.

Abstract: Methods are provided for a post-treatment process for use with coatings deposited via thermal spray and/or cold spray to modify the microstructures of the coatings and improve associated cohesion and adhesion properties. Such process includes performing ultrasonic consolidation of the spray coating as a post-treatment step after deposition of the spray coating onto a substrate. A system for spray deposition and ultrasonic consolidation is also provided.

Abstract: A cooling system for a cold spray nozzle or a thermal spray barrel and a fabrication method thereof are provided. The cooling system includes a sleeve with cooling fins that encapsulate a spray nozzle or barrel to enable heat transfer from the nozzle or barrel to the fins and then to the external ambient environment. The sleeve may optionally include one or more channels with cooling tubes to enable enhanced cooling with a cooling medium flowing through the tubes and across the fins.

Abstract: A computing system includes an input driver and a virtual input controller. The input driver is configured to receive input data from a first controller of a recognized data protocol and to provide the input data to an API of an application to control actions of a first participant in the gaming application. The virtual input controller is, in contrast, configured to receive input data from a second controller of a protocol incompatible with the input driver, translate the input data to the recognized data protocol; request a broadcast application identifier for a currently-broadcasting application from the broadcasting agent, and provide the translated input data to the input driver in association with the broadcast application identifier for controlling actions of a second participant in the application via the API of the gaming application.
