A battery charging assembly for a vehicle includes a vehicle battery and a charging module electrically connected to the vehicle battery and configured to supply electrical energy to the battery. A heatsink has a backside that faces the non-light-receiving side of the solar cell. The resulting cell nitride layer has a uniform thickness over the insulation layer and the lower electrode, thus eliminating punch-through and corner leakage problems. A modulator combines the amplified voice signal and the high frequency oscillation signal into a modulated signal. In addition, positioning components, arthroplasty jig blanks, and methods for making arthroplasty jig blanks are disclosed. When a read timing signal is output from timing signal selection section 124, image data reading section 127 reads the image data from storage section 126 according to the timing indicated by the read timing signal and outputs the image data to drive section 128.
