An improved bearing for use in movable sockets and suspension joints. Each of the plurality of shift drivers includes a magnet held by one of the shift member and the fixed member, a coil that is held by the other one of the shift member and the fixed member, and a yoke that is held by the other one of the shift member and the fixed member, and a portion of the protrusion is immersed in the gel. The present invention is also directed to a surface modified medical device, examples of which include contact lenses, intraocular lenses, vascular stents, phakic intraocular lenses, aphakic intraocular lenses, corneal implants, catheters, implants, and the like, comprising a surface made by such a method. A GPS system on the prime mover allows for tracking the spraying operation, while a time stamp in the processor software tracks the timing of the spraying operation. The method also includes determining relevance of relationships among the information elements in the ontological domain. The method enhances the efficiency of signal reception in the MIMO system and simplifies the algorithms of signal reception and soft decoding metrics generation.
