An embodiment of this invention is an apparatus for floor installation, repair, cleaning or ground proximity work. One such component is a movable member, such as a miniature precision reciprocating displacement pump head, which is driven by an actuator that comprises a shape memory alloy material. The solar cell unit includes a lower fixing case embedded in the body of the boundary stone and an upper fixing case separably assembled to the lower fixing case. The phase detection block compares phases of the input clock and the feedback clock and generates phase information, and quantizes a phase difference between the input clock and the feedback clock and generates phase codes. A beam portion of the narrowed emission from the laser is directed through the wavelength calibration module and a beam portion is directed through the detection and control unit when the laser beam is scanned through the optical transition line of each of the species within the module. The implant can be transferred to the tissue defect, with contours of the mold matching corresponding contours of the defect.
