Abstract: A sound attenuation panel that includes an incident wall and a frame unit connected to the incident wall. The incident wall defines an aperture therethrough. The frame unit includes multiple spoke members spaced apart from one another and radially extending from one or more central hub openings of the frame unit. The one or more central hub openings align with the aperture of the incident wall. The frame unit defines channels between adjacent pairs of the spoke members. The channels fluidly connect to the one or more central hub openings. The frame unit is configured to receive sound waves into the central hub opening through the aperture of the incident wall to dissipate the sound waves through the channels between the spoke members.

Abstract: Systems and methods for monitoring the health of an adhesive interface include the formation of an adhesive bond using an adhesive system incorporating molecular-scale magnetic markers covalently attached to polymer components, acquisition of images representing the distribution of magnetic markers within the adhesive bond at a first time and at a later time, and comparison of the images to detect displacement of the magnetic markers between the first time and the later time. The covalent link between the magnetic markers and the adhesive polymer components locks the magnetic markers in place as long as the adhesive bond remains healthy, so displacement of the magnetic markers between the first time and the later time indicates the presence of a bond defect. The images may be acquired using magnetic particle imaging and compared using digital image correlation. Chemical compositions for the magnetic markers are disclosed.

Abstract: The present disclosure provides coupling systems for use in industrial systems to removably couple one or more components to the industrial system. The coupling systems discussed herein employ a flexible sleeve in addition to one or more components. The flexible sleeve can have a component disposed therein. When pressure is applied to the flexible sleeve, the flexible sleeve constricts around the component, securing the component in the coupling system and thus to the industrial system. Once the component is secured, the industrial system executes one or more processes on the component. The coupling systems discussed herein can accommodate components of varying internal and external geometries as well as internal and/or external coatings and surface finishes.

Abstract: A sensing instrument includes a first electrode, a second electrode that surrounds the first electrode, and a sensing module configured to sense a capacitance of a material by applying a voltage between the first electrode and the second electrode while the first electrode and the second electrode are adjacent to the material. A method of operating a sensing instrument includes applying a voltage between a first electrode and a second electrode while the first electrode and the second electrode are positioned adjacent to a material. The second electrode surrounds the first electrode. The method further includes sensing a capacitance of the material based on a response of the material to the voltage.

Abstract: The present disclosure provides a cleaning system, including a first sub-chamber, a second sub-chamber adjacent to the first sub-chamber, and a third sub-chamber adjacent to the second sub-chamber. A first divider is positioned between the first and the second sub-chambers. A second divider is positioned between the second and the third sub-chambers. A vacuum system is coupled to the third sub-chamber to generate a vacuum pressure in the third sub-chamber that is less than a pressure of the first sub-chamber to create a pressure differential to induce a pressurized flow of a first cleaning media from the first sub-chamber to the third sub-chamber through an internal passage of a component positioned in the second sub-chamber. A filtering system is coupled to the first sub-chamber and the third sub-chamber to remove and filter the first cleaning media from the third sub-chamber and return the first cleaning media to the first sub-chamber.
