Abstract:
A system for monitoring a subsea structure is presented. The system includes a sensor disposed on or about one or more tubular components of the subsea structure, where the one or more tubular components of the subsea structure include a riser, a flow-line, and a subsea umbilical. Moreover, the system includes a controller operatively coupled to the one or more tubular components of the subsea structure and configured to detect an anomaly in the one or more tubular components of the subsea structure. A method for monitoring the subsea structure is also presented.
Abstract:
The present disclosure relates to methods for manufacturing porous mesh plates for use in ultrasonic mesh nebulizers, and the porous mesh plates manufactured by those methods. Cone-shaped dimples are first drilled in a substrate (e.g. a plate), but do not penetrate the bottom of the substrate. Next, the substrate (e.g. a plate) is subject to an electrochemical process to remove a layer of material from the surface of the substrate. Enough material is removed to allow the dimples to penetrate the substrate, thereby creating holes in the substrate. The size of the holes can be controlled by the conditions of the electrochemical process.
Abstract:
A nebulizer assembly configured for removable attachment to an ultrasonic actuator includes a base plate portion, a porous mesh member, and a cover member. The base plate portion includes an opening extending therethrough, and is substantially rigid such that ultrasonic vibrations from the ultrasonic actuator may be transmitted through the base plate portion to the porous mesh member to vibrate the porous mesh member. The porous mesh member is configured for passage therethrough of a nebulized fluid, and is disposed in the opening of the base plate portion proximate a fluid emission side of the nebulizer assembly. The cover member is disposed on a second side of the nebulizer assembly opposite the fluid emission side. The cover member covers the opening and defines a cavity between the cover member and the porous mesh member. The cavity is configured to retain a fluid to be nebulized.

Abstract:
A system includes a device and a contactless inductive force sensing system. The device includes a first band having a first magnetically encoded region with a first magnetic polarity spaced apart from a second magnetically encoded region having a second magnetic polarity. The device further includes a second band having a third magnetically encoded region with the second magnetic polarity spaced apart from a fourth magnetically encoded region having the first magnetic polarity. The contactless inductive force sensing system is used for measuring one or more mechanical force components of the device and generating a mechanical force component signal.

Abstract:
A system and method for controlling a microfluidic handling device is presented. One embodiment of the system includes a microfluidic synthesis cassette. Further, the system includes a synthesizer unit to receive the microfluidic synthesis cassette and execute one or more synthesis runs on the received microfluidic synthesis cassette to generate one or more radioactive doses. Also, the system includes an electronic dose tracker coupled to the microfluidic synthesis cassette to indicate a level of dose activity processed in the microfluidic synthesis cassette.
