Abstract: Systems and devices are provided for generating focused ultrasound pulses based on a transducer assembly having a piezoelectric layer coupled to an acoustic lens. In some example embodiments, the piezoelectric layer is a composite piezoelectric material having an acoustic impedance configured to match the acoustic impedance of the acoustic lens. The acoustic lens may be formed from aluminum, or an alloy thereof, and may have a distal surface having a non-spherical profile for producing a focal region that is smaller than an equivalent spherical lens. The acoustic lens may have an f-number less than unity. In some embodiments, the acoustic lens is coated with a polymer acoustic impedance matching layer that is compatible with deposition via chemical vapor deposition, such as a p-xylylene based polymer. In some embodiments, the acoustic lens is formed from aluminum or an alloy thereof, and the polymer acoustic impedance matching layer is a Parylene layer.

Abstract: A railroad tie plate placement system facilitates or enables a railroad crew to minimize interaction with railroad tie plates while placing railroad tie plates in a proper orientation on a railroad or railway track in preparation for insertion under a rail. Thus, the described railroad tie plate placement system reduces labor costs and decreases risk of injury while providing for consistent placement of tie plates.

Abstract: A bioassembly system having a tissue/object modeling software component fully and seamlessly integrated with a robotic bioassembly workstation component for the computer-assisted design, fabrication and assembly of biological and non-biological constructs. The robotic bioassembly workstation includes a six-axis robot providing the capability for oblique-angle printing, printing by non-sequential planar layering, and printing on print substrates having variable surface topographies, enabling fabrication of more complex bio-constructs including tissues, organs and vascular trees.

Abstract: A manned/unmanned aerial vehicle adapted for vertical takeoff and landing using the same set of engines for takeoff and landing as well as for forward flight. An aerial vehicle which is adapted to takeoff with the wings in a vertical as opposed to horizontal flight attitude which takes off in this vertical attitude and then transitions to a horizontal flight path. A tailless airplane which uses a control system that takes inputs for a traditional tailed airplane and translates those inputs to provide control utilizing non-traditional control methods.

Abstract: A veterinary subject intranasal administration device includes a first support member portion including a septum interface portion sized for insertion into a nasal passage of the veterinary subject; an actuation mechanism connected to the first support member portion; and a fluid conduit having a distal end opposite a supported end, the distal end sized for insertion into the nasal passage of the veterinary subject, the fluid conduit being flexible and configured to receive fluid from a fluid source and discharge the fluid through the distal end into the nasal passage, the distal end of the fluid conduit being unsupported and movable relative to the septum interface portion.

Abstract: Arrangements for dynamical travel threat assessment and control are provided. In some examples, a system may receive a request to schedule travel. The request may include one or more aspects. Based on the aspects, threat data may be requested. The threat data may be requested from a plurality of data sources including internal data sources and external data sources. Machine learning may be used to evaluate the threat data to generate or identify one or more potential threats associated with the requested travel. Based on the generated one or more potential threats, one or more actions may be identified. The actions may include completion criteria used to determine whether an action has been completed. The actions may be transmitted to one or more devices for execution. After executing the actions, action response data may be received and compared to the completion criteria to determine whether the requested travel should be authorized or denied.

Abstract: A ball, and in particular a baseball or softball, including one or more sensors such as accelerometers and/or inertial measurement units, and systems and methods using the same to improve a pitcher's pitching performance are described herein. In some embodiments, the ball may include one or more inertial measurement units and/or accelerometers capable of monitoring motion of the ball while it is thrown. Once a ball is thrown, in response to the inertial measurement unit(s) and/or accelerometer(s), one or more indicators may be caused to perform an action. For example, one or more user interfaces may be used to display graphs for illustrating a trajectory of a ball after it has been thrown. Various statistics, such as velocity, a change in vertical displacement, a change in horizontal displacement, and a spin rate may also be indicated on the user interface.
