Abstract: A robotic arm has a base with a top surface and an aperture therein. A shaft extends up through the aperture, and there is a gap between the shaft and an inner edge of the aperture. A splash guard may extend over said gap, and an indentation in said top surface may at least partially surround the gap. A seal, including a bearing and a barrier, is located in the gap. The bearing allows the inner and outer surfaces to rotate relative to each other. The barrier includes a plurality of annular outward-pointing flanges attached to an inner surface interleaved with a plurality of annular inward-pointing flanges attached to an outer surface. The flanges may be angled and have an upturned lip located at an inner edge of each flange. The seal may include a magnet attached to a flange.

Abstract: A rotary seal is located in a gap between an inner surface and an outer surface. A radial bearing allows the inner and outer surfaces to rotate relative to each other. A radial barrier includes a plurality of annular outward-pointing flanges attached to the inner surface interleaved with a plurality of annular inward-pointing flanges attached to the outer surface. The flanges may be angled and have an upturned lip located at an inner edge of each flange. The radial seal may include a magnet. A robotic arm has a first housing with a top surface and an aperture therein. A shaft extends up through the aperture, and there is a gap between the shaft and an inner edge of the aperture. A splash guard may extend over said gap, and an indentation in said top surface may at least partially surround the gap.

Abstract: A glove for padding a human hand. The inventive device includes a glove member having open truncated finger tubes and a thumb tube extending therefrom. Pneumatic chambers are coupled to a palm web of the glove and can be individually inflated to a desired pressure to selectively pad the glove.
