The present invention relates to a novel series of polymers which have been prepared by blending hydrophobic biocompatible, biodegradable polymers or copolymers, such as poly, and a biocompatible, amphipathic copolymer having a water absorption ratio of about 2 or less. The sleeve includes a guiding element capable of cooperating directly or indirectly with said outer projection, so as to limit rotation of said sleeve. The second embodiment includes a housing having a sealable lid compartment for baby wipes and a separate lid compartment for rash cream that is provided with a pump mechanism for allowing the user to pump the rash cream from the reservoir without the need for opening the lid. Responsive to detecting a condition or violation, the embodiment selectively determines whether any change to the users or permissions of a specified role is needed. In an example embodiment, the method includes first raising a base having media thereon, ceasing the raising the base upon detecting the media, detecting an absence of the media, and second raising the base upon the detecting the absence of the media.
