Devices, systems, and method for treating urinary incontinence generally rely on energy delivered to a patient’s own pelvic support tissue to selectively contract or shrink at least a portion of that pelvic support tissue so as to reposition the bladder. Each of the polishing elements is secured so as to restrict lateral movement thereof with respect to others of the polishing elements, but remains moveable in an axis normal to a polishing surface of the polishing elements. Global addressing may also be implemented by reading data from or writing data to the same register file address for each processing element. The control unit determines whether the collision of the piston occurs on the basis of an output signal from the collision detection unit, and resets maximum amplitude data of the piston of the linear compressor when the collision occurs. The geometry data can designate a plurality of subsections of the surface. Also, a resistor connects a gate of the first transistor to a gate of a second transistor.
