A print head maintenance device is used in a printing device. Assigning an instance of a CPD to a design element can indicate, for example, whether the element can be switched on and off, or whether the element can operate over a range of voltages. The support member is configured to be placed adjacent a vaginal apex of a patient. As a result, the properly oriented caps can be conveyed to a capping machine configured to apply each cap to a cap-receiving portion of a container. In various examples, base station power control in a mobile network may be implemented in the form of systems, methods andor algorithms.
