Abstract: A tubing component, and methods of forming, for a particulate material delivery assembly including a particulate delivery device to deliver a mixed particulate solution to a patient. The tubing component includes a material including a material density, and a determined thickness sufficient to shield a delivery line connector of a particulate delivery device from at least 90% of a radiation dose. The delivery line connector is configured to receive the mixed particulate solution from the particulate delivery device of the particulate material delivery assembly, and the determined thickness of the tubing component is calculated based on the material density to achieve shielding of the delivery line connector by the material of at least 90% of the radiation dose. The tubing component includes an integral wall of the delivery line connector, an outer sleeve configured to be removably disposed about the delivery line connector, or combinations thereof.

Abstract: Systems and methods for managing devices, such as computing devices, are disclosed. In an aspect, one method comprises determining one or more available communication networks, determining a first position in association with the one or more available communication networks, if a change is detected in the one or more available communication networks, or if the first position is not of sufficient quality, determining a second position, and if no change in the one or more available communication networks is detected, and the first position is of sufficient quality, retrieving the first position.
