Abstract: A bidirectional thermally actuated component includes a heating element and wax material provided in an enclosed housing wherein the heating element is activated to melt the wax which expands to cause movement of the housing or an element mounted therein. When the heating element is deactivated, the was hardens and constricts to allow for movement in the opposite direction based on application of a force in the opposite direction, which may be provided by a biasing spring or a second actuator. An adjustable medical device may include the thermally actuated component to control adjustment of the device.

Abstract: Filesystem driver software can receive a file access request indicating that an application process is requesting to access a target file in a filesystem, Network filter driver software can receive a connection establishment request indicating that the application process running on the processing apparatus is requesting to establish a connection over a network with a target endpoint. According to the present disclosure, one or both of: a) the filesystem driver software is configured to grant or deny the file access request in dependence on state information from the network filter driver software, and/or b) the network filter driver software is configured to grant or deny the connection establishment request in dependence on state information from the filesystem driver software.

Abstract: Provided herein are radiopharmaceutical compositions and uses thereof. The radiopharmaceutical compositions can comprise one or more stabilizing agents, an aqueous vehicle, and a conjugate that comprises a targeting ligand and a radionuclide bound to a metal chelator. The targeting ligand can be a small molecule compound or a peptide such as a monocyclic peptide. The targeting ligand can be configured to bind with a tumor target. The stabilizing agent can comprise a radiolysis stabilizer, a free metal chelator, and/or a pH stabilizer. Further provided herein are methods of preparing the radiopharmaceutical compositions and methods of treating cancer by administering the described radiopharmaceutical compositions.

Abstract: An anchor assembly for connecting a curtain airbag to a side structure of a vehicle includes an elongated track configured to be connected to the side structure of the vehicle behind a vehicle trim piece that covers the side structure and forms a surface visible from within a passenger compartment of the vehicle. An anchor is configured to move along the track. The track includes sidewalls that define an interior channel that extends along the length of the track, and a slot that extends along the length of the track. The anchor includes a shank and a roller that is connected to the shank and rotatable relative to the shank. The roller and a portion of the shank to which the roller is connected are positioned in the channel and are movable along the channel when the anchor moves along the track. A portion of the shank extends through the slot, is positioned on an exterior of the track, and is configured to be connected to the curtain airbag.

Abstract: A spinal adjustment system including at least one thermally actuated pump element.

Abstract: A system for stimulating a sympathetic chain includes an electrode assembly that is configured to attach to a bone in proximity to a targeted portion of the sympathetic chain. The electrode assembly includes a cathode and an anode. The system also includes a power supply connected to the electrode assembly and configured to deliver power to the electrode assembly. The electrode assembly generates an electrical field between the cathode and the anode when power is delivered to the electrode assembly. The electrical field reaches the targeted portion of the sympathetic chain to provide electrical stimulation to the targeted portion of the sympathetic chain.

Abstract: A pump mechanism for dispensing a sealant is described. The pump mechanism can include a housing comprising a cavity; a tubing track arranged in the cavity, the tubing track having a curved surface inward from the housing; a tubing arranged in proximity to the curved surface of the tubing track; a rotor assembly arranged inward from the curved surface and the tubing, the rotor assembly comprising a rotor and a first roller in contact with the tubing, the first roller compressing the tubing to reduce fluidic communication between a first end and a second end of the tubing; a motor in operable communication with the rotor assembly; and a computing device configured to control a rotational speed of the rotor based on a velocity of a tool center point (TCP) of the robot.

Abstract: Aspects of the disclosure are directed towards generating a trajectory for use by a robot to perform an operation on a target object. A method includes a robot instructed to traverse a surface of the target object from the starting position and obtain sensor input from a sensor system of the robot using a first trajectory specified by a CAD file for the target object. Sensor input that includes a first height to the target object, a width of the seam, and a depth of the seam may be received. A second trajectory may be generated for traversing the surface of the target object and that modifies the first trajectory based on the sensor input. The robot may be instructed to move to the starting position and traverse the surface of the target object using the second trajectory and apply a sealant to the seam.

Abstract: A method of using a catheter assembly for inserting in a fluid filled space in a body includes providing a main body having a first end portion and a second end portion. The first end portion is positioned within the fluid filled space. The second end portion is adjusted to extend outwardly from the fluid filled space when the first end portion is positioned within the fluid filled space. A catheter tip is connected to the second end portion of the main body. The catheter tip includes a housing having a cavity defined therein and a rotating element positioned within the fluid filled space. The rotating element is rotated within the cavity of the housing to impart movement of the first end portion of the main body within the fluid filled space.

Abstract: Among the various aspects of the present disclosure is the provision of devices, systems, and methods for tracking the positions and orientations of at least one bone screw implanted within a surgical site. The disclosed device includes an extension that includes an extension base configured to couple to the bone screw, a marker arm coupled at one end to the extension base in a hinged arrangement, and an optical marker attached to a free end of the marker arm opposite the hinged attachment. The optical marker includes a pair of lenticular arrays in a coplanar arrangement in which the major axes of the lenticular arrays are mutually perpendicular. Each lenticular array is configured to display different hues at different viewing angles. The disclosed method includes transforming a single image of a surgical site containing at least one bone screw and extension into the global positions of each bone screw based on the pixel positions and hues corresponding to the lenticular arrays of each optical marker.
