Abstract: A medical dressing is provided. The dressing has a central portion and a border portion, and comprises a backing layer, an adhesive body contact layer and a pad arranged in the central portion between the backing layer and the adhesive body contact layer. The pad is symmetric about a longitudinal center line and the dressing comprises a lobed portion on each side of the center line. The central portion of the dressing has a tensile strength in the longitudinal (y) direction of at least 60 N, preferably at least 70 N at an elongation of 25%, as measured by the test method ASTM D 882-12. The medical dressing may be used for pressure ulcer prevention, such as at the sacrum region of a human body.

Abstract: A robotic tank system may be used for performing functions related to a structure such as a tank or a hull structure, either which may be used for storage or ballast, comprises a robotic system comprising a base, a crane connected to the base, an end effector operatively connected to the crane, a control unit operatively in communication with the crane and the end effector, and a power unit operatively in communication with the crane, the end effector, and the control unit; a console operatively in communication with the control unit and with the power unit; and a tool selectively attached to the end effector, the tool operatively in communication with the control unit, the console, and the power unit.
