Abstract: Devices and methods for reducing vibrations. Methods include inserting a device for reducing vibrations within a pressure-control device, where the pressure-control device includes at least one movable element. The device for reducing vibrations includes a first body comprising a first material inserted adjacent to the at least one movable element and a second body comprising a second material, positioned radially opposite the first body. In one or more embodiments, the method also includes moving the at least one movable element of the pressure-control device and absorbing a portion of vibrations, introduced by moving the at least one movable element, using the device for reducing vibrations.

Abstract: A disclosed choke valve insert includes a cage, bonnet, valve stem, and seal assembly. The cage has an orifice configured to receive a flow of fluid. The bonnet is disposed superior to the cage and has a stem bore and cavity. The seal assembly is disposed within the cavity and around the stem bore. The seal assembly includes a seal housing, inner seal, and outer seal. The seal housing has an inner slot and outer slot. The inner seal is disposed within the inner slot and configured to prevent a portion of the flow of fluid from leaking superiorly past the inner seal. The outer seal is disposed within the outer slot and configured to allow the portion of the flow of fluid to return to the stem bore inferior to the inner seal when the inner seal fails.

Abstract: An articulating interbody fusion device may include a body including a plurality of interconnected pores, and a recess portion having a first border portion and a second border portion spaced apart from the first border portion. The articulating interbody fusion device may further include an articulating connector configured to be positioned within the recess portion. One of the body and the articulating connector may include an aperture, the other of the body and the articulating connector may include a post positioned within the aperture, the articulating connector may be rotatable relative to the body, and the articulating connector may be irremovable from the body.

Abstract: A suction head for an extraction cleaner including a base forming a suction chamber and a suction outlet in fluid communication with the suction chamber; and a piezoelectric element coupled to the base, the piezoelectric element comprising a first surface open to the suction chamber, a second surface facing an external environment away from the suction chamber, a thickness between the first surface and the second surface, and a through-via through the thickness open at both the first surface and the second surface. An extraction cleaner including the suction head.

Abstract: A soil enhancement system and method is configured to eradicate undesirable plant-life while providing enhancing nutrients to the soil. The method includes applying non-toxic acid-based solution to one or more invasive plants in a soil. The method also includes dehydrating, by the non-toxic acid-based solution, the one or more invasive plants by disturbing a water-retaining capacity of a number of cells of the one or more invasive plants. The method further includes generating one or more beneficial nutrients; and delivering the one or more beneficial nutrients to the soil.

Abstract: A method for spinal surgery may include receiving a planned rod contour and using a flexible surgical sensor to generate a three-dimensional path, wherein the three-dimensional path may represent a spinal contour of a patient. The method may further include bending a spinal rod according to one of: the planned rod contour, the spinal contour of a patient, and a modified contour derived from the planned rod contour and/or the spinal contour of the patient.

Abstract: A suction head for an extraction cleaner including a base forming a suction chamber and a suction outlet in fluid communication with the suction chamber; and a piezoelectric element coupled to the base, the piezoelectric element comprising a first surface open to the suction chamber, a second surface facing an external environment away from the suction chamber, a thickness between the first surface and the second surface, and a through-via through the thickness open at both the first surface and the second surface. An extraction cleaner including the suction head.

Abstract: A data storage system can connect a data storage controller to a host and a data storage device. A first reference state corresponding to a first zone of the data storage device can be incremented in response to a first version of data being assigned to the first zone by the data storage controller. A second version of the data may be written to a second zone of the data storage device prior to populating a recently freed list with the first zone having an incorrect reference state. The first zone can be allocated by the data storage controller for new data without altering the incorrect reference state that is subsequently written to the first zone as directed by the data storage controller.

Abstract: An ozone treatment system which is usable in enclosed or confined spaces for the inactivation of pathogens such as bacteria and viruses in these spaces.

Abstract: An example biological tissue graft includes a body formed from a flexible biological tissue, the body having a first end and a second end opposite the first end. The biological tissue graft also includes an aperture positioned in the second end of the body that is sized to receive the first end of the body therethrough.

Abstract: A primary lens element fabricated of laser protective glass has proximal and distal faces, a central extent and a peripheral extent. A secondary lens element fabricated of lead oxide has proximal and distal faces, a central extent and a peripheral extent. The secondary lens is operatively coupled to the primary lens forming a lens laminate ground to form a composite lens with a prescription. The composite lens has a central extent of an enlarged thickness and a peripheral extent of a reduced thickness.
